Title: Gas safety device
Inventor: KONDO YUJI
IPC: F16C13/02
Filed: 1987-07-07
Abstract: PURPOSE:To operate a cutoff valve only at the time of danger and to take a proper measure, knowing how gas is used without operating the cutoff valve in the other cases by sending signals of gas use conditions to a control center to be input to a computer. CONSTITUTION:Signals of a gas checking meter N1, a reset switch N2 and a gas leakage sensor N3 are input to a gas safety device A to be sent to a computer of a control center through a telephone line L. When preset conditions are satisfied, the computer is adapted to operate according to the conditions. When the quantity of gas used exceeds the preset flow, a cutoff signal is generated to operate a cutoff valve N4, and when it exceeds the maximum change flow, instantaneously the cutoff valve N4 is not operated, but the state is informed. Accordingly, at the time of danger, the cutoff valve N4 is operated, and at the time of low risk, a proper measure can be taken without operating the cutoff valve.

Abstract: PURPOSE:To remarkably shorten a delivery term by a method wherein the threshold voltage is adjusted by an ion implantation after the formation of gate metallic patterns, and a mask programmable ROM (eye of ROM) is formed in the latter stage of the manufacture process. CONSTITUTION:A P type si substrate is isolated with a channel stopper and a field oxide film. and a doped poly Si gate 8 and an N layer 10 are formed on a gate oxide film 7 and covered with an SiO2 film 9.

Next, a resist mask 17 is applied, and an enhance type MOS is converted into a depletion type by a P ion implantation resulting in the formation of the eye 18 of the PROM14. The resist 17 is removed, and an Al wiring containing Si is provided and protected with an Si3N420. Since the threshold voltage is varied by an ion implantation through the poly Si gate pattern in this manner, a special area for the eye of the ROM is un- necessitated resulting in a high integration, and the writing into the eye of the ROM can be performed in the latter process. Therefore, the delivery term of a device can be extremely shortened.

The light transmitted through the second ring band and the third ring band form side lobes without convergence on the information recording surfaces. When such side lobes are made incident on the photodetector, the side lobes form the flares.  The removal of the flares is executed by the opening limiting means 24 arranged between a laser/detector integrated unit 2 and a beam splitter 13. In such a case, the opening limiting means 24 may be a stationary diaphragm and the opening shape may be circular.
