Title: Semiconductor storage device
Inventor: NOZAKI SHIGEKI
IPC: G11C11/4074
Filed: 1981-12-07
Abstract: PURPOSE:To prevent a malfunction due to the fluctuation of the feed potential, by separating an earth potential supply wiring to a peripheral circuit of a memory cell from that to a counter electrode and then connecting both wirings to a common part of earth potential supply of a low level of imopedance. CONSTITUTION:A chip 20 of a random access chip memory contains a cell 21, a sense amplifier 22 and a peripheral circuit 23 such as a column decoder, etc. The feed wiring to these function circuits is formed with an operating voltage feed pat 24 as well as with an earth potential feed pat 25. A wiring 26 is connected to a counter electrode 28 of a capacitor 27 of the cell 21. In such a constitution, no effect of the operating state of the circuit 23 emreges to the wiring 26. Furthermore it is possible to form the wiring 26 so that the effect of the resistance of the wiring 26 can be neglected. As a result, the fluctuation of feed voltage is very small to the cell 21. Thus the malfunction is avoided for the amplifier 22, and the destruction can be avoided for the information stored in the cell 21.

Title: Protection device for locker cover made of synthetic resin
Inventor: YAJIMA JUNICHI
IPC: F02D17/04
Filed: 1991-08-08
Abstract: PURPOSE:To prevent lowering of sealing ability and to suppress the increase of a cost by providing a control circuit to stop the feed of fuel to an engine when an engine cooling water temperature is transferred from a cylinder head and increased to a high temp near the melt point of a locker cover. CONSTITUTION:After the starting of an engine, it is discriminated by means of a detecting signal from a water temperature sensor whether a present cooling water temperature exceeds 145 deg.C. The reason why 145 deg.C forms a reference value is such that temperature transferred to a locker cover from a cylinder head heated by means of a combustion heat is approximate 200 deg.C being the melt point of the locker cover. When it is discriminated that a water temperature exceeds 145 deg.C, injection of fuel is stopped and a fuel injection state is continued for a given time by means of a timer. Since operation of an engine is temporarily stopped and the cylinder head is cooled, overheating of the locker cover is prevented from occurring. When the feed of fuel is stopped, a signal by means of which the display lamp of an instrument panel is lighted ON is outputted. By keeping a cooling water temperature at 145 deg.C, a trouble owing to fuel cut is prevented from occurring to normal operation.
