Title: Backup circuit for power unit of memory
Inventor: HIRATA KOJI
IPC: G06F1/00
Filed: 1987-12-28
Abstract: PURPOSE:To extend the backup time by providing a regulator and a diode between a backup power source and a memory and minimizing the backup voltage without reducing the capacity to suppress the discharge current. CONSTITUTION:When a power switch 12 is turned on, 6V voltage is generated from a power supply circuit 11 and is stabilized to about 5.3V by a three- terminal regulator 13 but the output is about 6V because of the existence of a diode 15 of about 0.7V forward voltage, and a cathode potential P1 of a diode 14 is 5.3V. The generated voltage of a battery 16 is stabilized to about 5V by a micro power regulator 17 and is outputted, and a cathode potential P2 of a Shottky diode 18 is about 4.6V. Consequently, about 5.3V of the potential P1 is supplied to a DRAM 1 because of P1>P2 and the storage operation is possible. When the switch 12 is turned off, P1<P2 is true and 4.6V of the potential P2 is supplied to a RAM 1, and the storage operation of the RAM 1 is held because this voltage is within the allowable range of the RAM 1.

When the cuff pressure P becomes equal to or higher than the initial pressure P1, the cuff pressure P is increased at low speed (Q3), and the cuff pressure P is increased at constant speed when blood pressure can be measured. Next, Korotkoff's sounds K are detected (Q4), and are continued until judgment is made (Q5) on whether or not identification of the blood pressure is finished. The cuff pressure P at a prescribed point of time is measured by a series of operations composed of Q3, 4 and 5, and the blood presure is measured when the pressure is increased.

Title: Control device for automatic transmission
Inventor: MURAKAWA RYUJI
IPC: F16H61/16
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To prevent shifting from being shifted up to fourth speed at the unexpected time causing occupants to be in a sense of incongruity in a device which allows a prohibition condition to fourth speed to be released after a constant period of time has elapsed since a specified condition was ready. SOLUTION: When an acceleration pedal is returned at the time of running on an uphill road, up-shifting to fourth speed is prohibited. This prohibition is released by returning the acceleration pedal when a vehicle is moved to a flat road from the up-hill road, and shifting to fourth speed is thereby permitted. When the acceleration pedal is returned after the vehicle has moved to the flat road, since shifting to fourth speed is usually expected, no body will be in a sense of incongruity even if the aforesaid shifting is actually actuated.
