Title: Fuel supply system of engine
Inventor: OKAWA TAKESHI
IPC: F02M17/38
Filed: 1992-10-19
Abstract: PURPOSE:To prevent useless fuel supply during no-firing rotation, and to eliminate lack of initial power by providing a by-pass communicating an upper stream part of a carbureter with a lower stream part in an inlet air passage connected to an inlet air port of an engine, and by providing an opening and closing valve which opens during a running period, and closes during a stationary period. CONSTITUTION:A by-pass 18 is provided in an inlet air passage 7 of an engine 3 on both sides of a carbureter 9 so as to communicate an upper stream passage 7a to a lower stream passage 7b. An electromagnetic valve 19 is provided at the middle of the by-pass 18, and in addition, a chamber 20 is provided in the lower stream part of the electromagnetic valve 19, and further, an exit port 18a for the lower stream passage 7b is connected to the position just before an inlet port 10. This electromagnetic valve 19 is closed during a stationary period. So, the pressure in the lower stream passage 7b coincides with that in the upper stream passage 7a. Thus, even if the engine 3 rotates in a state of no-firing, fuel supply to a fuel chamber 11 is prevented. Lack of power at the start is prevented by the fuel remained in the lower stream passage 7b.

Title: Sense amplifier circuit for semiconductor memory
Inventor: TSUTSUI HIROAKI
IPC: G11C11/419
Filed: 1989-10-27
Abstract: PURPOSE:To decrease the propagation delay time of a sense amplifier circuit almost without increasing energy consumption by operating a second serial circuit only for a fixed period including a time point, when an input signal to a sense amplifier is switched, after an address input signal is changed. CONSTITUTION:A serial circuit composed of pMOS Q6 and Q2a and nMOS Q4a and Q7 is parallelly connected to a serial circuit composed of a pMOS Q2 and an nMOS Q4 for load drive. When any one of address input signals A1, A2,..., An is changed, the change is detected and a pulse generating circuit 3 generates a one-shot pulse with certain fixed pulse width. This pulse becomes a control signal CS to control the Q6 and Q7 after passing through a delay circuit 4, and the Q6 and Q7 are conducted only during a certain fixed period. Thus, since the effective gate size of the load driving transistor is enlarged when the Q6 and Q7 are conducted, the propagation delay time of the sense amplifier circuit can be shortened.

Title: Semiconductor device
Inventor: TAKADA TOSHIAKI
IPC: H01L21/768
Filed: 1989-10-26
Abstract: PURPOSE:To prevent the delay in switching speed and malfunction caused by miniaturization by using the upper surface and the side surface of a lower wiring layer as connecting surfaces, and electrically connecting the wiring layer to an upper wiring layer. CONSTITUTION:The part of a through hole 5 is made larger than the width of a lower wiring layer 2. The side surface of the lower wiring layer 2 is used as the same way as the surface. The lower wiring layer 2 is electrically connected to an upper wiring layer 6. In this constitution, even if miniaturization advances and the width of the wiring becomes narrow, the contact area between the lower wiring layer 2 and the upper wiring layer 6 is not reduced because the upper surface and the side surface of the lower wiring layer 2 are used as the contact surfaces. The resistance of the through hole 5 is hard to increase in this structure. Therefore, the delay in switching speed and malfunction are not caused in a semiconductor device. The decrease in yield rate due to deviation from standards is not present, and the miniaturization of the semiconductor device can be made to advance.

Abstract: PURPOSE:To manufacture a hydrogen storing alloy member having a long life and excellent powdering resistance by impregnating a compacted body of a hydrogen storing alloy powder comprising a porous body with Mg in a nonoxidative atomsphere under pressure, and then providing thermal diffusion treatment of Mg. CONSTITUTION:A hydrogen storing alloy powder such as a TiMn alloy, etc., is compacted (process 1) into a formed body. This alloy powder has preferably <=100mum average particle size and compacted under about 7ton/cm<2> pressure into 85% density ratio. The obtd. compacted body comprising a porous body is impregnated with Mg in a nonoxidative atomsphere such as Ar gas under about 2kg/cm<2> pressure (process 2). The amt. of Mg added is preferably about 2.5-10wt.% based on the amt. of the hydrogen storing alloy. Then the body is heated at 200-650 deg.C under pressure for thermal diffusion treatment of Mg (process 3). Thereby, Mg can be melt-compounded and diffused in the porous hydrogen storing alloy. This Mg absorbs expansion stress in the alloy and prevents cracks when hydrogen is stored. Thus, decrease in the hydrogen amt. stored in the alloy can be suppressed and the alloy can be prevented from powdering.
