Title: Measuring method of static current consumption for semiconductor integrated circuit
Inventor: INAHATA SHINJIROU
IPC: G01R31/26
Filed: 1991-09-17
Abstract: PURPOSE:To enable detection of a leak current because of a defect of a transistor by lowering a power source voltage to a second power source voltage after the application of a first power source voltage of a CMOS type semiconductor integrated circuit under test. CONSTITUTION:A positive power source voltage is applied and after raised to the first level, the level of the positive power source voltage is lowered to the second level in the order of an input terminal of an integrated circuit and the positive power source. The first power source voltage to be applied first to the positive power source is taken high sufficiently. If so, the level of an internal node 10 after the positive power source voltage level is changed to the second level can be held higher than the level of the positive power source voltage and the voltage level of the node of a complete internal CMOS circuit. Thus, a potential difference between the gate and source of a P-type transistor 1 is held higher sufficiently than a threshold voltage thereof thereby enabling the cutting off of the P-type transistor 1 completely.

Title: Flame detection device
Inventor: NARITA KAZUMI
IPC: G01J5/14
Filed: 1990-10-04
Abstract: PURPOSE:To quicken the response to the gas shut-off by a constitution where a flame detection device consists of a thermocouple for detecting flame, a winding in which the output current of the thermocouple flows, saturable magnetic twin cores that have a winding to which high frequency signals are inputted, and a fail-safe window comparator for checking the level of the output signal that is generated against the output current of the thermocouple. CONSTITUTION:Window comparators R1 and R2 that are fail-safe are resistors with a resistance sufficiently lower than the input resistance of the window comparator. The fail-safe comparator 6 checks the level of the terminal voltage developed in a winding 3 in place of a winding 4 by a fail-safe window comparator 6. Further, when electric current I is developed in the thermocouple by flame, this current is detected by the window comparator 6, and a gas shut-off mechanism is released by the output signal of the window comparator, and it is possible to supply gas to the burner. When the flame is extinguished, the current I disappears and the window comparator detects a drop in the input level and shuts off the output. With this arrangement the gas can be shut off even with a little decrease in the current of the thermocouple with the flame extinguished, and, furthermore, it is possible to carry out high speed shut-off.
