We have developed an image processing LSI "ISP-IV" for real-time imaging systems such as a security surveillance system, an advanced inspection system, and a traffic control system. The main characteristics of the ISP-IV are as follows: (1) the video interface, PCI controller, memory controller, and image processor are unified on one chip. (2) Basic image processing (Laplacian, smoothing, median filter, etc.) is processed in 73.5 MHz (512/spl times/512 pixels image with 8 bits/pixel is done in 3.6 ms). (3) Tracking/search processing is high speed due to the nine-parallel Gray Search Engine Units (GSEUs). (4) Color extraction of YUV color images is processed in real-time by functions supporting color transform. In this paper, we report the performance of the ISP-IV by evaluating several practical applications using the IP5000 Series equipped with the ISP-IV.

Information processing is fast developing in various sectors along with the spread of computer technology. The same goes for the commodity production and distribution industries where the bar-code system is increasingly utilized as one of the most useful tools for recognizing unique information related to each commodity. While handy type bar-code readers are normally used by retail shops where small amounts of diverse products are handled, a system to quickly and automatically read out bar-code data pasted on a continuous flow of products is required for use in production sites or distribution centers where large volumes of products are handled. Demands at site for the functionality and performance level of such systems are quite challenging. For instance, it is impossible to specify the location to paste a bar-code on a round container like a hat box. Cardboard cartons also come in variable sizes in very large quantities. In order to cope with such situations, the bar-code recognition devices have been developed using the most advanced image processing technology in both soft- and hardware. The notable features are as follows: 1) small bar-codes are read from a large sectional area using a multi-camera; 2) individual recognition is achieved without disturbing product flow by high speed parallel processing; 3) the camera is capable of reading objects (bar-codes) from a distance between one to two meters (to allow the facility more flexibility in design); 4) the mainstream bar-codes in the distribution industry such as Code 39 and ITF are supported; and 5) the high level of recognition efficiency and safety.

Self-aligned punch-through stopper (SPS) MOSFETs are made using high energy ion implantation;punch-through stopper (PTS) layers are formed after gate electrode delineation. The SPS structure features: 1) a retrograded PTS layer with a gradually increasing impurity profile;and 2) a relatively lower impurity concentration around the source and drain region. These characteristics of the PTS structure permit both junction capacitance reduction and adjustment of threshold voltage (V-th) (specifically, a reduced V-th and suppressed reverse short-channel effect) and improved current drivability, short-channel characteristics, and hot-carrier immunity. The proposed structure is also effective in reducing process steps because only one implantation is needed to adjust the profile.

Network node processors (NNPs), which can execute application programs and can cooperate with each other via high-speed LANs, have become essential components for distributed on-line systems. DCNP is a data communication management system for NNP. DCNP provides unified communication interfaces and high-performance and highly reliable communication services. We present an addressing technique which unifies program interfaces for node-to-terminal communications and inter-node communications. Socket interface extensions for improving performance and techniques for highly reliable inter-node multicast communications on multiple LANs are also presented. DCNP has been implemented in UNIX l kernel on fault-tolerant mini-computers, and is currently operating in actual on-line systems. © 1992 IEEE.

NATURAL CONVECTIVE HEAT-TRANSFER BETWEEN VERTICAL PARALLEL PLATES WITH SYMMETRICAL AND ASYMMETRIC HEATING

引用

KAGAKU KOGAKU RONBUNSHU 1987年第1期13卷 116-121页

作者： HANZAWA, T ISHIHARA, H SEKIGUCHI, K FUJII, T SUZUKI, Y KATO, K Dept. of Chem. Eng. Gunma Univ. Hitachi Condenser Co. Ltd. Kurashiki Kako Co. Ltd. Hitachi Process Computer Engineering Co. Ltd.

To analyze the heat transfer phenomenon in electronic circuit plates, natural convective heat transfer between two vertical parallel plates, with symmetric or asymmetric uniformly heated wall, was investigated experimentally in the range of high Grashof number (Gr=103-107). The local heat transfer coefficient was strongly affected by the axial distance of the plate in the case where distance and temperature difference between plates were small. Average Nusselt number was affected by Grashof number, distance and temperature difference between the plates. An empirical equation for average Nusselt number in the two vertical parallel plates was obtained.
