Patent JP-H07297394-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: KAWAURA HISAO
IPC: H01L29/78
Filed: 1994-04-26
Abstract: PURPOSE:To make the output voltage be a bistable binary output by a construction wherein the junction between a drain region and an impurity containing region forms a tunnel diode. CONSTITUTION:This semiconductor device is equivalent to a circuit of MOSFET 107 and a diode 108 connected in series. In or on a drain 103 of the MOSFET 107, an N<+> layer 106 of a reverse conductivity type to the one of the drain 103 is provided. A junction between the N<+> layer 106 and the drain 103 is very shallow and has a steep profile and, therefore, the diode 108 is made a tunnel diode. An output voltage of the semiconductor device constructed in this way is determined as a voltage value at a point of intersection of the output characteristic of the MOSFET 107 and that of the tunnel diode 108. Since different voltages are outputted by changing an input voltage, the output voltage can be a bistable binary output. According to this constitution, an improvement in the speed of operation can also be attained.

Title: Gas concentration and refining device
Inventor: SATO SHIGEO
IPC: A61M16/00
Filed: 1994-04-26
Abstract: PURPOSE:To immediately display the required function at the time of reuse without any functional deterioration by keeping a section airtight between two valve means including an adsorption floor and a buffer tank in such state as charged with product gas having higher pressure than the atmospheric pressure during a period when an operation switch is turned off. CONSTITUTION:The valve V14 of a buffer tank 28, upon receipt of a stop instruction from an operation switch, immediately closes, but when a time phase is at an intermediate pressurizing process, the valve V14 enters a terminal regenerative time phase, after the end of the pressurizing process. Furthermore, when the time phase is at an intermediate vacuum regenerative phase, the valve V14 ends the terminal regenerative time phase. Also, after the end of the terminal regenerative time phase, a valve V13 between the buffer tank 28 and an adsorption floor 24 is opened, while valves V11 and V12 are closed. After a reverse charge time phase for filling the floor 24 and piping with product gas, a pump means 12 stops and each closing mechanism is closed. In this state, airtightness is maintained, but the volume of product gas in the buffer tank 28 is so made that the internal pressure of the buffer tank 28 and the floor 24 becomes higher than the atmospheric pressure, even when the product gas is returned into the floor 24.

Title: Air conditioner
Inventor: KATSUKI HIKARI
IPC: F24F11/02
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent the blowout of cold wind at the time of stoppage of a compressor by the working of a protective means at heating operation. SOLUTION: At heating operation, this air conditioner detects the temperature of a heat exchanger, and when the temperature of the heat exchanger goes up, this makes the wind a breeze (LL) at a temperature T1, and performs the blow based on the set quantity of wind after it reaches a temperature T2 (T1<T2). Moreover, in case that the temperature of the heat exchanger having gone up drops to a temperature T3 when a user seeks to operate a compressor, this makes it a breeze (LL), and further after it drops to a temperature T4(T3>T4), this stops the blow. Hereby, even if the temperature of the heat exchanger drops due to the stoppage of the compressor, this can prevent cold wind from being blown out.

Title: Low pressure cvd method
Inventor: ARIZONO MITSUO
IPC: H01L21/205
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To provide a low pressure CVD method in a conventional horizontal low pressure CVD apparatus for suppressing peeling off of a film formed on a dummy wafer caused by thermal stress from the wafer to thereby prevent drop of its yield. SOLUTION: A dummy wafer 9 has an average surface roughness Ra of 0.5 to 1.5 μm that is 3 times larger than that of a conventional dummy wafer. The roughness of the wafer makes a CVD film deposited on the dummy wafer 9 hard to peel off. As a result, the number of particles released from the dummy wafer 9 and deposited on a wafer 8 as a product can be remarkably reduced and thus a yield can be improved. The dummy wafer 9 having a CVD film of about 1 or 2 μm thick deposited thereon has been exchanged with a new one. Thus, the exchange life of the dummy wafer 9 can be prolonged to about 3 times.
