Patent JP-H06140623-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: ITO HIROYASU
IPC: H01L29/43
Filed: 1992-10-22
Abstract: PURPOSE:To realize a homogeneous oxide film by obtaining a polycrystalline silicon layer where halogen atoms having an atom radius which is larger than that of impurity is added to grain boundary of silicon in view of bonding with free bonds of silicon atoms in the grain boundary before impurity is added. CONSTITUTION:A lattice portion of a gate electrode portion 103 is formed of Si particles under the single crystal condition and lumps of such lattice portion gathers in large number without orientation to form p-Si. The grain boundaries 109 are defined by the boundary between Si particles. Here, the added halogen atoms bond with free bonds of Si on the grain boundaries and impurity atoms (phosphorus) precipitated in the grain boundaries are as much reduced. Thereby, a degree of activity is suppressed and an oxidation rate of grain boundaries can be delayed by reducing the number of uncoupling hands in the grain boundaries of the p-Si layer which is a cause of progressing the reactions. Accordingly, a more homogeneous oxide film can be formed, making easier the adjustment for formation of oxide film.

Title: Mold assembly of plastic filter and molding thereof
Inventor: KOTAKI DAIZO
IPC: B29C33/42
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To realize the roundabout influx of a molten resin flowing in the net grooves of a first cavity insert in the net grooves of a second cavity insert by a method wherein this mold assembly has a plurality of the inserts respectively having the net grooves arranged in the fashion that the net grooves of the inserts adjacent to each other are not directly connected with each other. SOLUTION: On a first cavity insert 4, rhombic net grooves are formed by intersecting grooves 5 leaning to the left and grooves 6 leaning to the right with each other. On a second cavity insert 3, rectangular net grooves are formed by intersecting longitudinal grooves 7 and lateral grooves 8 with each other. The inserts are so arranged relative to each other that the longitudinal grooves 7 and the lateral grooves 8 on the insert 3 do not directly connect with the net grooves of the grooves 5 leaning to the left and those of the grooves 6 leaning to the right. When a molten resin is poured into the center of the second insert 3, the molten resin flowing in the longitudinal grooves 7 and the lateral grooves 8 tend to flow in the grooves 5 leaning to the left and the grooves 6 leaning to the right of the first insert 4.  However, since the grooves of the first insert 4 and the grooves of the second insert 3 do not connect directly to each other, the influx in the grooves 5 leaning to the left and the grooves 6 leaning to the right is performed by roundabout routes through very minute gaps at the fitting part between the insert 3 and the insert 4.

Abstract: PURPOSE:To obtain a highly sensitive and highly accurate sensor excellent in impact resistance with a simple construction, by etching an Si plate on both sides thereof to form a mobile electrode playing a role of a weight at the tip of a cantilever beam and a glass plate having a solid electrode is bonded on both the sides of the Si plate. CONSTITUTION:An Si plate 1 with a diameter of 3-4 inch, and a thickness of 0.2mm is etched on both sides thereof to form a mobile electrode 3 playing a role of a weight at the tip of a cantilever 2 with a thickness of several ten m. The mobile electrode 3 is etched so as to be 2-3mum in the depth from the surface of the Si plate. Glass plates 6 and 7 having solid electrodes 4 and 5 on the surface thereof are bonded on both sides of the Si plate 1. A distance changes between the solid electrodes 4 and 5 and the mobile electrode 3 depending on a Y-wise acceleration thereby detecting acceleration as change in the capacity between the electrodes. The cantilever 2 is so thick as to be excellent in the impact resistance. A resonance point gives about 1kHz to achieve a high accuracy at 0-10Hz as measuring range without damping. A small gap between the electrodes assures a high sensitivity.

IPC: A01B63/10
Filed: 1987-12-08
Abstract: PURPOSE:To provide the above drive where an oil amount-regulating mechanism to change flow channel area is connected to a lift arm in a specified state and a valve to open or shut a channel arranged in parallel with the oil channel to be reduced in the area is opened or shut through a hydraulic pressure for raising the lift arm, thus decreasing the landing speed of the working machine. CONSTITUTION:A hydraulic pressure for raising is applied on an oil-charging or discharging channel to allow a valve 18 to be opened, and a hydraulic cylinder is fed with a large amount of hydraulic fluid to raise a lift arm in high speed. During the lift arm is made to descend to a prescribed position, said lift arm is lowered in high speed with an oil amount-regulating mechanism 15 extending the channel, and when said lift arm is lowered below the prescribed position, said mechanism 15 then reduces the channel area through the mechanical connection. At this time, the valve 18 is kept shut, therefore, the amount of the oil to be discharged from the hydraulic cylinder is decreased, thus the lift arm descends at low speed.
