In recent years, electronic control of automatic transmissions, which provides an effective means of satisfying increasingly strict fuel efficiency requirements and improving drivability and shift quality, is applied to an increasing number of automobile models, and increasingly larger sections of automatic transmissions are electronically controlled. A new automatic transmission control theory which ensures high robustness and sufficient control performance has been developed through application of the H/sub /spl infin// control theory in order to make HONdA automatic transmissions more marketable. This paper reports that their control performance was favorable. This was verified by tests with actual vehicles, and the main processes to which it was applied.< >

NAVAL ENGINEErS JOUrNAL 1994年第1期106卷 123-136页

作者： MEYEr, Jr The Author:is manager of hydrofoil technology in the Hydrofoil Group of the Systems Department of the David Taylor Research Center. He holds bachelors and masters degrees in aeronautical engineering from Rensselaer Polytechnic Institute and has done additional graduate work at the Massachusetts Institute of Technology in the same field. Since joining the David Taylor Naval Ship R&D Center in 1971 he has been associated with advanced naval vehicles. Meyer has authored a number of DTRC reports AIAA and ASNE papers on the subject of hydrofoils and hybrid marine vehicles he holds several patents in this technical area. Prior to his current employment at DTRC Meyer held several research and development long-range planning and engineering management positions with Boeing-Vertol Trans-Sonics Inc. Air Force Cambridge Research Center and the Aero-Elastic Laboratory at MIT. Meyer has served on the AIAA Marine Systems and Technologies Committee the High Speed Vehicle Committee of the American Towing Tank Conference and now as president of the International Hydrofoil Society. He is a member of the American Society of Naval Engineers American Institute of Aeronautics and Astronautics and the Society of Sigma Xi.

The purpose of this paper is to provide a review of hybrid hydrofoil vehicle technology and feasibility designs, both military and commercial, that have been explored during the last several decades. A hybrid hydrofoil consists of a conventional monohull form with the addition of a long, slender, single strut and lower body added to its keel. The lower body buoyant lift is augmented by the dynamic lift from a fully-submerged foil system. Foil dynamic lift comes into play at speeds of about 12 to 15 knots and above, at which time the upper hull is lifted from the water surface leaving only the small waterplane of the single strut at the interface. The foil automatic control system maintains predetermined flying height and provides a stable platform in waves. The foil surfaces are sufficiently powerful to counter roll, pitch and heave motions that would be imparted to a conventional monohull in waves. Propulsion of a hybrid hydrofoil is provided by one or more prime movers in the upper hull, either driving through a mechanical Z-drive, or an electric transmission system, to one or more propellers on the stern of the lower hull. An alternate arrangement is to place the entire propulsion system in the lower hull, thereby eliminating a Z-drive requirement. The hybrid hydrofoil designs to be described will include USCG patrol craft, U.S. Navy long-range missile patrol craft, multi-mission deployable vehicle, multi-mission support vehicle, and small combatant, along with several commercial versions of the hybrid hydrofoil concept.

Loss of life and property losses totaling tens of billions of dollars have piping engineers scrambling to specify ''fire-safe'' components in fire-prone locations: on board ships, and in power plants, refineries, and other perilous applications. Fire-safe valves, the first line of defense in containing a fire, were introduced some 25 years ago, with fire-safe actuators following soon afterwards. Little attention has been given, however, to designing and selecting the other piping components such as flanges, gaskets, bolting, and fittings to ensure their integrity in a fire. Just like in an electric circuit where, if a single component in series fails, the flow of electricity stops;likewise, the failure of a single piping component could result in a fire of catastrophic proportions. This paper discusses the availability of critical fire-safe components for Navy shipboard piping systems and provides some simple solutions which, if implemented, could prevent such a disaster. discussion is provided on how a fire starts and how it reaches catastrophic proportions, the definitions of survivability and fire-safe components, materials of construction, component design, fire-safe valves and actuators, gaskets, pipe flanges, flange bolting, pipe fittings and unions, brazing and welding, insulation, composite piping materials, and other related subjects. details are also provided on 78 fires that have occurred on Navy surface ships in the last ten years and their causes.

damping Characteristics of TiNi shape Memory Alloys

Metallurgical Transactions A 1993年第10期24卷 2189-2194页

作者： Lin, H. C. Wu, S. K. Yeh, M. T. Department of Materials Science Feng-Chia University Taichung Republic of China Institute of Materials Science and Engineering National Taiwan University Taipei Republic of China Materials R&D Center Chung-Shan Institute of Science and Technology Lung-Tan Republic of China

The damping characteristics of TiNi SMAs have been systematically studied by using techniques of resonant-bar and low-frequency inverted torsion pendulum. Experimental results show that both the martensite phase (M) and r phase (r) have high damping due to the movement of twin boundaries. Because the B2 parent phase (B2) has smaller damping, it is suggested that this may come from the dynamic ordering process of lattice defects. In the transformation re-gions of B2 ↔ M, B2 ↔ r, and r ↔ M, there are maxima of the damping capacity which are attributed to two contributions. One arises from the plastic strain and twin-interface move-ment during the thermal transformation, which obeys a linear variation of peak heightsQ−1 max vst att ≥ 1 °C/min. The other originates from the stress-induced transformation formed by the applied external stress which dominates atT < 1 °C/min. The elastic modulusE of martensite and the r phase is lower than that of the B2 phase, and a modulus minimum appears in the transformation region.

The absorption of plasma proteins is an important event at the blood-material interface, and strongly affects subsequent cellular interaction and thrombus formation. Although considerable efforts have been expended to elucidate the mechanism of protein adsorption and the role of absorbed protein layer at the blood-material interface, there has been little knowledge of how the initial adsorbed proteins are maintained or changed in a time-variant process in in vivo long-term implantation. In this study, we described detailed analyses concerning the characterization of adsorbed proteins on HEMA-styrene block copolymer surfaces (HEMA-st) and poly(ethylene oxide)(PEO) grafted Biomerâ® (B-PE04K) for in vivo long-term canine vascular graft implants as well as in vitro short-term experiments. Biomer vascular grafts (6 mm I.d., 7 cm in length) were fabricated by a dip coating and the luminal surface was modified with PEO grafting, HEMA-st coating, or Biomer coating (control). These surface modified grafts were recirculated for different time intervals (5, 15, 30, 60 and 120 min) using citrated canine whole blood. The grafts were then implanted in the abdominal aortas of dogs and evaluated for graft patency and protein adsorption. The adsorbed proteins (albumin, IgG and fibrinogen) were quantified using an in situ radioimmunoassay. Surface protein layer thickness was measured by transmission electron microscopy (TEM). Visualization of absorbed plasma proteins (albumin, IgG and fibrinogen) was performed with TEM using an immunoperoxidase double antibody technique. In in vitro recirculation systems, albumin and IgG showed similar Langmuir type pattern onto all test surfaces. On B-PEO4K surfaces, fibrinogen adsorption kinetics demonstrated 'Vroman effect'. The Biomer and B-PE04K grafts occluded within 1 month, while HEMA-st grafts were patent for over 3 months. Biomer and B-PE04K showed thick multilayers of adsorbed proteins, and the thickness increased with implantation periods

The rechargeable lithium/cobalt oxide electrochemistry is examined for its use in powering underwater vehicles. It has been successfullv developed in 30 amp hour capacity cells. A comparative studv with the silver oxide/zinc technology, most frequently used for this application, revealed lithium's superior performance. Lithium/cobalt oxide gave more charge-discharge cycles with 40-50% higher energy density. Lithium's advantage was especiallv marked at -2-degrees-C, where it cycled four times longer than silver cells. Projections indicate that, at the 600 amp hour cell size, the battery will have an energy density of 120 watt hours per pound resulting in a more durable and cost effective power source for naval vehicles than currentlv possible.

Preparation and characterization of polyurethane‐type macroazo initiators for block copolymerization

Macromolecular Chemistry and Physics 1993年第3期194卷

The use of dipropylene glycol in the polyaddition of 2,2′‐azobis(2‐cyanopropanol) (ACP) with hexamethylene diisocyanate results in soluble polyurethane‐type macroazo initiators (PUMAI) in high yields. By adjusting the amount of ACP used, the number‐average molecular weight of the polyurethane segments was adjusted in the range from 2000 to 6000 at an azo content in the PUMAI's of 0,18 to 0,5 mmol/g‐polymer (determined by UV). 13 C NMr spectroscopy of the PUMAI's showed that no significant decomposition of azo groups occurred during polyaddition. At 80°C the PUMAI's initiated effectively the radical solution polymerization of vinyl monomers. As supposed from extraction results and the polymerization mechanism, block copolymers are formed. The whole process seems to be adequate for industrial applications.

PHOTOVOLTAIC PrOPErTIES OF SINTErEd CdS/CdTE SOLAr-CELLS dOPEd WITH CU (JOUrNAL OF THE ELECTrOCHEM SOCIETY VOL 139, PG 3351, 1992)

All polycrystalline CdS/CdTe solar cells doped with Cu have been prepared by a screen printing and sintering method. Cell parameters of the sintered CdS/CdTe solar cells have been investigated in an attempt to find out the optimum doping conditions and concentrations of Cu by adding various amounts of CuCl2 either into CdTe layer or into back contact carbon layer. Cell parameters of the sintered CdS/CdTe solar cells which contained various amounts of CuCl2 in the CdTe layers before sintering stay at about the same values as the amount of CuCl2 increases up to 25 ppm, and then decreases sharply as the amount of CuCl2 further increases. The Cu added in the CdTe layer diffuses into the CdS layer during the sintering of the CdS-CdTe composite at 625-degrees-C to densify the CdTe layer and causes the decrease in the optical transmission of CdS resulting in the degradation of the cell performance. In case the Cu dopant was dispersed in the back carbon paint and was followed by annealing, all cell parameters are improved significantly compared with those fabricated by adding CuCl2 in the CdTe layer before sintering. A sintered CdS/CdTe solar cell which contained 2 5 ppm CuCl, in the carbon paste and was annealed at 350-degrees-C for 10 min shows the highest efficiency. The efficiency of this cell is 12.4% under solar irradiation with an intensity of 80.4 mW/cm2.
