Title: Gas detector
Inventor: IKEZAKI NOBUYA
IPC: G01N27/00
Filed: 1993-04-16
Abstract: PURPOSE:To test a gas detector by using gas with a density lower than an allowable level by adjusting the amplification degree of an electrical signal outputted from a gas sensor when the gas is sensed. CONSTITUTION:The test of the gas detector is performed by connecting the contact (b) of a change-over switch 2a by the operating signal of an alarm control panel 3, and adding the electrical signal outputted from the gas sensor 1 on the amplifier 2b of an amplification device 2. Also, the amplification degree of the amplifier 2b is set corresponding to the kind of the gas to be monitored, however, in such a case, the amplification degree of the amplifier 2b is set so as to be equal to a level where an alarm signal can be outputted from a detector 5 by the electrical signal outputted from the switch 2a even when the density of leaking gas sensed by the gas sensor 1 is lover than the allowable level where no alarm signal is outputted from a detector 4 in the normal monitoring state of the leaking gas. Therefore, the alarm signal is outputted even when the density of the leaking gas sensed by the sensor 1 is lower than the allowable level, and it is added on the alarm control panel 3.

IPC: H01L21/28
Filed: 1990-04-05
Abstract: PURPOSE:To prevent the surface of silicon substrates from being damaged and prevent an increase in contact resistance by forming contact holes after an insulating film is formed on the silicon substrate. CONSTITUTION:After an N-type area 2 is formed on the surface of a P-type silicon substrate, an interlayer insulation film 3 is formed on the surface of the silicon substrate. Next, a recess 3a which does not reach the surface of the silicon substrate 1 is formed by performing a reactive ion etching by using a photoresist 4 as a mask. Next, a contact hole 3b which reaches the surface of the silicon substrate 1 is formed by performing wet etching. Since the wet etching process has been performed when the surface of the silicon substrate 1 is exposed, no damaged layer is formed thereon by the etching. After a quite thin silicon oxide film 1a is formed on the surface of the silicon substrate 1, an aluminum alloy electrode film 5 containing silicon is accumulated and formed by sputtering.

Title: Production indication card
Inventor: OKUDA KENZOU
IPC: G06K7/015
Filed: 1984-05-04
Abstract: PURPOSE:To prevent the generation of wrong signals when a production indication card is carried obliquely by forming two reading position confirming holes with a distance X secured between them and ihibiting formation of an opening for information codes at the places near a circular are drawn with radius X centering on the position confirming hole. CONSTITUTION:Eight information code holes 2-1-2-8 and a parity check hole 4 are provided at the upper part of a production indication card 20. While reading position confirming holes 8-1 and 8-2 are formed with a distance X secured between them at the middle part of the card 20. Then the formation is inhibited for infirmatioi cord holes at places near circular arcs of radius X drawn centering on each reading position confirming hole. When the card 20 passes through the reading position, an optical sensor 8A is set opposite to the hole 8-1. Then optical sensors 8A-8C output the ON, OFF and ON signals, i.e., the read signals of information codes only when the sensor 8C is set opposite to the hole 8-2. When card 20 is carried obliquely, sensors 8B and 8C are never set opposite the hole 8-1 although the sensor 8A is set opposite to the hole 8-1. This avoids a case where a wrong information code is read.

Title: Infrared image sensor
Inventor: KIMATA MASAAKI
IPC: H01L27/146
Filed: 1981-06-08
Abstract: PURPOSE:To eliminate the variance of sensitivity at a photodeecting part, by applying the backward bias to a P-N junction formed between an impurity region and a semiconductor substrate and preventing the minor carrier caused at the peripheral part of the P-N junction from entering the photodetecting part. CONSTITUTION:An impurity region 5 having a conduction type opposite to a semiconductor substrate is formed on the 1st main surface between a photodetecting part 3 and a peripheral part 2, and the backward bias is applied to a P-N junction formed by the region 5 and the semiconductor substrate. First the semiconductor substrate is formed P type, and as a result the region 5 is N type. Therefore the positive voltage is applied to the region 5 to the semiconductor substrate. Then the electrons produced at a peripheral part 2 are almost absorbed while they pass under the region 5 and before they enter the part 3 since the region 5 has the lower potential than the semiconductor substrate to the electron. Thus the electrons produced at the part 2 never enter the part 3. At the same time, the apparent variance of sensitivity can be eliminated for the part 3.

Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: Not to have an influence on a driving circuit a controlling circuit and a static induction transistor(SIT) by connecting a fuse between a drain pattern and an external electrode pattern of the SIT. SOLUTION: A chip H of an SIT is brazed to a copper foil drain pattern G on a nitride aluminum substrate F. One side of a fuse J is brazed to a drain pattern part I of the SIT and another side is brazed to a drain pattern K for an external electrode. A copper electrode is brazed to the drain pattern K for the external electrode as an external electrode of the drain. In ease of the SIT being broken by some reason, inserting the fuse before the drain has no influence on a driving circuit, a controlling circuit junctioning to the said circuit and other SITs and maintenance and reliability of the device is improved, even if a big current flows in, because the fuse breaks and the current is shut down. Also mounting man-power and wiring man-power are reduced because the fuse is contained.
