Title: Timer control method
Inventor: AZUMA YOSHIKI
IPC: G04F10/00
Filed: 1995-06-29
Abstract: PURPOSE: To simplify a timer-monitoring program for a simple processing by subtracting the integral value of the count value of a table located in front of each table from an actual count value and registering it at the count value. CONSTITUTION: A timer count value as a count value which a table for timer in queue structure stores is so constituted as to become the actual timer value of the table when the timer count values are added in the order of check. Therefore, a value obtained by subtracting the integral value of the count values at a table located in front of the table is registered as the count value to be registered at each table. For example, a value 4b of a count value 15-45 obtained by subtracting a count value 15-45 of a table B from an actual count value 60 of a table C is registered as the count value of the table C. Therefore, when monitoring the timer, the count value of a top table is successively subtracted and a next table becomes the top table when the count value reaches 0, thus making simple a monitoring program.

Title: Logical gate circuit
Inventor: KIYOZUKA NOBORU
IPC: H03K19/088
Filed: 1982-10-27
Abstract: PURPOSE:To prevent a power supply line from the induction of noise and to prevent a logical circuit from the reduction of life by suppressing transient current completely at the time turning on power supply voltage. CONSTITUTION:When the power supply voltage VCC is less than the voltage VBEQ16 between the base and the emitter of a transistor (TR) 16, all TRs are disconnected and power supply current ICC does not flow. When the VCC rises and reaches the VBEQ16, base current is supplied to the TR 16 and the TR 16 is connected. Since the collector of a phase inversion TR is fixed on the voltage VCEQ16 between the collector and the emitter of the TR 16, a buffer circuit (consisting of TRS 11, 13) in the logical gate circuit is disconnected during the connection of the TR 16. When the VCC rises moreover up to the logical level of a logical gate circuit, and a buffer circuit is still continued to be disconnected even when TR 5, 9 are conducted. Consequently, transient current flowing through a resistor 12 and TRs 11, 13, 9 is not generated in the logical gate circuit as compared to an ordinary circuit.
