Product design is an important process in industry whereas it has been usually performed based on aesthetics and static strength rather than on dynamical features of the product in use, or more specifically, in grasping. In this paper, dynamical analysis of grasping is to be discussed. Because it is difficult to deal with an actual hand dynamically interacting with an object, a hand model in dynamical simulation environment is used for the analysis. The hand model moves corresponding to a hand wearing a data glove. In the simulation, contact force vectors are calculated for each contact point between the hand model and the object to be grasped. © 2010 SICE.

AlNiLa metallization technology is introduced for AMLCD as gate electrodes. Ni can effectively prevent Al diffusing into Si-based layer while La can obviously increase uniformity during AlNiLa deposition than that of conventional Al-Nd alloy. According to the electrical measurement results, the compatibility of AlNiLa in TFT has been verified. © 2010 SID.

A Compton camera is an imaging system for three-dimensional (3D) distribution of gamma emitting sources based on Compton scattering interaction. The measurement error on energies and positions directly leads to uncertainties on the formation of cones and degrades the spatial resolution of the reconstructed images. Mostly the limited energy resolution, Doppler broadening and position segmentation of detectors cause angular and positional uncertainties on measurements. Since the conical surfaces are delocalized by angular and positional uncertainties into image space, degradation of spatial resolution may be severe depending on the distance (or depth) from the Compton camera. In order to enhance the deteriorated spatial resolution due to angular and positional uncertainties, this study investigates 3D Gaussian point spread function (PSF) incorporable into listmode ordered subset expectation maximization (LMOSEM) as a part of system matrix. Especially the depth-dependent PSF is applied as resolution recovery (RR) technique by image-space convolution operation. We investigated two different RR approaches: one (denoted by LMOSEM-RR-F) is when the convolution is performed in forward projection step only, and the other (denoted by LMOSEM-RR-FB) is when it is performed in both forward and backward projection steps. Using Monte Carlo data for 7 point sources at different depth from the Compton camera, the fitted axial and radial FWHM functions were obtained as FWHM axial (i)=0.2442i+1.054 and FWHM radial (i)=0.2369i-1.005, respectively. The simulation results showed that both RR approaches with depth dependent PSF gave an improvement on spatial resolution comparing to LMOSEM without RR techniques. Although LMOSEM-RR-F provided better resolution than LMOSEM-RR-FB, LMOSEM-RR-FB could still be useful for low counting statistics in measurement.

The paper developed a block-wise approach for ICA algorithms which can improve the computational efficiency of ICA without the degradation of performance for the separation of biomedical signals. Source signals including electrocardiogram (ECG), electromyogram (EMG) and 60-Hz sinusoid are linearly mixed for experimental tests. The mean-square errors (MSE) between the original sources and the separated signals are calculated for the evaluation of separation performance. These results demonstrated that the proposed block-wise approach can achieve the desired separation performance of signals in a more efficient way.

This research presents a systemic method to the innovative design of M14 rifle trigger mechanism based on TRIZ. We used the System Functional Analysis to define the functions for the components of trigger mechanism, the Strategy Edition to evaluate the value of the components for selection and deletion of the lower value components to simplify the trigger mechanism. The technical parameters, the invention principle, and the contradictory matrix of TRIZ were applied to solve the contradictory problem generated during the innovative design process. Finally, we created the 3D modeling of parts and simulation of the new trigger mechanism to prove its feasibility. After we applied this systematic method to the M14 rifle trigger mechanism, not only fewer components has made, but the trigger mechanism newly designed can do all the functions of original design;it can be also replace the original trigger mechanism to install into M14 rifles.

Recently, the development of a versatile robot hand aiming at the application to an artificial arm or a humanoid robot is in demand. In this paper, omni-directional bending mechanism which is called "double-screw- drive mechanism" was applied to a robot hand. The robot hands with two fingers and three fingers were built. For the robot hand with three fingers, each fingertip was controlled so as to track the elliptical orbit and experiment was carried out. The DSD robot hand succeeded in rotating the cap of the PET bottle and removing the cap from the bottle. © 2009 SICE.

With steady increase in energy consumption, the vulnerability of the fossil fuel supply, and environmental concerns, the U.S. department of Energy (DOE) has initiated the Next Generation nuclear Power Plants (NGNP), also known as Very High Temperature Reactor (VHTR). The VHTR is planned to be operational by 2021 with possible demonstration of a hydrogen generating plant. Various engineering design studies on both the reactor plant and energy conversion system are underway. For this and related Generation IV plants, it is the goal to not only meet safety criteria but to also be efficient, economically competitive, and environmentally friendly (proliferation resistant). Traditionally, heat exchanger (HX) design is based on two main approaches: Log-Mean Temperature Difference (LMTD) and effectiveness-NTU (Ε-NTU). These methods yield the dimension of the HX under anticipate condition and vice-versa. However, one is not assured that the dimension calculated give the best performing HX when economics are also considered. Here, we develop and show a specific optimization algorithm (exercise) using LMTD and simple (optimal) design theory to establish a reference case for the Printed Circuit Heat Exchanger (PCHE). Computational Fluid Dynamics (CFD) was further used as a design tool to investigate the optimal design of PCHE thermohydraulic flow. The CFD results were validated against the Blasius correlation before being subjected to optimal design analyses. Benchmark results for the pipe flow indicated that the predictive ability of SST k-ω is superior to the other (standard and RNG k-Ε and RSM) turbulence models. The difference between CFD and the empirical expression is less than 10%.

Mass optimization studies of potential upper and lower axial shields for the Affordable Fission Surface Power System are described in detail and a complete shield is developed to meet the radiation dose requirements of 10 14 n/cm2 fast (E>1 MeV) neutron fluence and 2 Mrad gamma dose at the Stirling power converters and 5 rem/yr at a lunar outpost located 1 km from the center of the reactor. The upper and lower axial shield sections are developed separately, and then combined with the previously developed radial sections to produce a complete shield. Complete lithium hydride, borated water and boron carbide shields are developed. Lithium hydride yields the lightest complete shield at 6215 kg, followed by the borated water shield at 6663 kg, and the boron carbide shield at 8315 kg.
