Filed: 1988-03-25
Abstract: PURPOSE: To minimize a false delay in a memory cell circuit by connecting across a bit line and a writing line to be selectively transmittable via MOS transistor when a gate is connected with a signal. CONSTITUTION: When a writing column line 40 and a reading column line 42 are addressed at the same time, a signal from AND gate 44 increases in the level.

Therefore, data are written in a memory cell 10 in this state. Here, since each line is connected with each other to be directly transmittable, it is not required to wait until the data are written in the memory cell from the bit lines 32 and 36 via TR24 and 28 and are returned to the bit lines via TR26 and 30, but the data supplied by the writing bit lines 32 and 36 are read out quickly.

Title: Device for detecting oscillation of power feeding system
Inventor: YAMAZAKI MIKIO
IPC: G05F1/10
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To intentionally generate an obvious oscillation state and to make informable that a power feeding system is set in an oscillation state even when the oscillation condition of the power feeding system is approximate to a critical state and an obvious oscillation state is not secured by connecting the constant power load to a power feeder line to start the oscillation at need. SOLUTION: A constant power load circuit 6 is connected to a power feeder line 8 to add the load in addition to two function circuits. A load state is secured by actuating a DC/DC converter 10 serving as the circuit 6 by a start switch 7 before a power feeding system oscillation detector 9 is removed from a power feeding system including the line 8 even when the power feeding system is approximate to a critical state of the oscillation condition and an obvious oscillation state is not secured. The power feeding system is forcibly oscillated in a state where the total value of the circuit 6 of the power feeding system exceeds the load P of an original constant power load device 1. Thus, an oscillation detecting/alarming circuit 5 can detect an oscillation state or an oscillation critical state.

Title: Traveling device of vehicle at constant speed
Inventor: SUZUKI KOUICHI
IPC: F02D29/02
Filed: 1982-05-04
Abstract: PURPOSE:To continue the constant speed running in a set car speed, by shifting down a gear of an automatic transmission, when an actual car speed is decreased less than the set car speed by a predetermined value or more and a signal outputted for the constant speed running at the set car speed is maximum. CONSTITUTION:A discriminating circuit 13 gives an output when a difference between the actual car speed VA and the set car speed VM is a predetermined value VB or more, and a discriminating circuit 14 gives an output when a difference between the actual car speed VA and the set car speed VM is a predetermined value VC or more. Since the relation of VB>VC is decided, the output is produced from the discriminating circuit 14 at the car speed drop. When an output signal IA of an actuator drive circuit 5 is inputted to the discrimination circuit 15 and the signal IA is equal to a maximum value VB possible for output as an output signal (that is, IA-IB=0), the output signal is given from the discrimination circuit 15. When the output signal is given from both of the discriminating circuits 14 and 15, the AND condition of an AND gate 16 is established and a kick-down switch 17 is turned on. As a result, a hydraulic changeover solenoid is energized and the shift-down is attained.
