Title: Readout circuit for dynamic ram
Inventor: YAMAUCHI HIROYUKI
IPC: G11C11/34
Filed: 1987-12-29
Abstract: PURPOSE:To suppress the amount of fluctuation of pre-charge potential on a bit line generated at the time of division by coupling a second switching device being operated complementarily with a first switching device which divides or couples the bit line to the bit line. CONSTITUTION:The bit lines (9-11) are pre-charged at the same potential by turning ON the switching devices 3 and 4 first. Next, at the time of reading out the signal of a memory cell 7, the device 3 is turned OFF, and the bit line on a side from where no signal is issued is separated. Here, since the devices 3 and 4 are N-type MOSFET switching devices, a trailing signal which falls from a high level to a low level is inputted as a gate signal in an OFF state, and the potential of the bit line fluctuates to a negative side via a capacitor between a gate and a drain. Therefore, the signal in a direction to negate the fluctuation (leading signal rising from the low level to the high level) is inputted to the gate of the switching device 1 by a control circuit 2. Next, a read out micro signal is amplified by rising a word line by using FF circuits 14 and 5, and it is read out to an I/O line via a column switching device 12.

Title: Metallic thin film resistor for superconducting integrated circuit
Inventor: NUMATA HIDEAKI
IPC: C23F4/00
Filed: 1993-12-28
Abstract: PURPOSE:To provide an easy-to-handle alloy resistor for superconducting integrated circuit whose resistivity is high and variable in an Nb superconducting integrated circuit. CONSTITUTION:As a resistor in an Nb superconducting integrated circuit, a total ratio solid soluble alloy is used, which is constituted by adding at least one or more kinds of alloy elements of Mo, W, Ta, V, Nb which are different from a base metal in the base metal. A complete solid solution alloy by combination of five elements of Mo, W, Ta, V, Nb is free from generation of regular phase and compound and is a single phase in all the composition ranges; therefore, a high resistance value can be acquired in a wide composition range and the resistance value can be controlled by a composition rate. Since it shows little variation of resistance value with time caused by diffusion, etc., and completely solves in solid with Nb of a wiring layer, compound and different phases are not generated also in an interface between Nb of a wiring layer and an alloy resistor, thus resulting in small contact resistance and small change of contact resistance with time.

Title: Signal detection circuit
Inventor: MIYAZAKI HIROSHI
IPC: H03K17/13
Filed: 1989-12-26
Abstract: PURPOSE:To simplify the constitution by ORing an AC zero cross signal and an AC input voltage detection signal so as to synthesize both the signals. CONSTITUTION:An AC input voltage signal detection circuit 3 outputs an H level logic signal as an AC input voltage detection signal. Then an OR circuit 8 ORs an AC zero cross signal detected by an AC zero cross signal detection circuit 2 and an AC input voltage detection signal detected by the circuit 3 to synthesize them and the result is outputted as a synthesis signal. Normally the AC zero cross signal is sent as the synthesis signal and an H level AC input voltage detection signal is outputted when the AC input voltage detection signal is outputted. Then the synthesis signal controls a microcomputer 6 and a device 7 to be controlled. Thus, one circuit 5 is enough in the device controlled by the synthesis signal and one input pin of the microcomputer 6 is enough to simplify the constitution.

Title: Steering locker
Inventor: MASAKI MIKIO
IPC: E05B83/00
Filed: 1987-12-31
Abstract: PURPOSE:To raise the operability of a steering locker by a method in which when a key cylinder is turned to locking position, the rotation of the key cylinder is interrupted, and key is pushed at unlocking position to release the couplement between a coupler and a coupling portion in such a way as to enable it to turn. CONSTITUTION:A notch 30 is formed in the periphery of the flange 15 of a key cylinder 16, end a coupler 32 with a compressive spring 33 is attached. A circular arc-shaped cam 38 is formed on the inner surface of a cover 13, and the cam 38 is coupled with the coupler 32 at on-position. When the key is turned from on-position to locking position, the coupler 32 comes into contact with the stopper face 38a of the cam 38 at the unlocking position of the cylinder 16 to interrupt the rotation of the cylinder 16. When the cylinder 16 is pushed at the unlocking position, the couplement of the coupler 32 with the cam 38 is released and the cylinder 16 is allowed to turn to the locking position, The operability of the steering locker can thus be raised.
