Title: Exposing device
Inventor: IWAMATSU SEIICHI
IPC: H01L21/027
Filed: 1981-03-11
Abstract: PURPOSE:To prevent the temperature rise of the surface when exposing, and to obtain a minute pattern by forming an ejecting port contacting a gas controlled at a peripheral temperature or lower with the surface of a wafer. CONSTITUTION:The wafer 2 is placed on a base 1, and mounted under a chuck 3 for forming the flatness of the surface of the wafer. N2 cooled is ejected from the pipe 4 of the chuck 3, passed through the surface of the wafer and discharged from a pipe 5. Beams 6 passing an optical system are imaged onto the wafer 2. According to this constitution, the minute pattern of submicron can be worked particularly at desired accuracy because the temperature rise (approximately 2 deg.C) of the surface of the wafer through exposure can be prevented and undesired treatment due to a temperature change is obviated.

IPC: B65H26/00
Filed: 1990-02-16
Abstract: PURPOSE:To obtain the left quantity of paper with high precision from the output of the prescribed feed quantity of the paper for calculation and the detection output of the turning angle of the paper in roll form by constituting a display of left quantity of paper so that the revolution angle of the paper in roll form is detected by the prescribed feed quantity of the sent-out paper and calculation-displaying the left quantity of the paper. CONSTITUTION:A feed quantity measurement part 40 outputs a prescribed transfer quantity of paper, and the turning angle of the shaft of the paper in roll form for the prescribed transfer quantity is detected from the output of a shaft turn angle detection part 30. In other words, when the left quantity of the paper in roll form is much, the circumferential length is long, and the turn angle is small, and as the left quantity becomes less, the circumferential length reduces, and the turning angle increases. Therefore, the left quantity of the paper in roll form is calculated by a calculation part 50 from the output value of the shaft turn angle detecting part 30 and the feed quantity measurement part 40, and can be displayed by a display part 60.

Title: Fuel cell system and flow path freezing prevention method for fuel cell system
Inventor: TAKI MASAYOSHI
IPC: H01M8/06
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To prevent the plugging of a flow path caused by the freeze of condensed water by the drop of outside temperature, in the flow path of an exhaust gas from a fuel cell. SOLUTION: A fuel cell system 10 has a methanol adding path 66. The methanol adding path 66 is a flow path connecting a methanol tank 13 for storing methanol, which is a raw material for producing a fuel gas supplying to a fuel cell 20 and an oxidizing exhaust gas path 61, into which an oxidizing exhaust gas from the fuel cell 20 is introduced. By supplying methanol to the oxidizing exhaust gas path 61 through the methanol adding path 66, methanol is mixed to produced water which is condensed in the oxidizing exhaust gas path 61. Since the condensed water mixed with methanol drops in its melting point, even if the outside temperature drops during the operation of the fuel cell system 10, the condensed water does not freeze.

Title: Pressure gage having vibration proof function
Inventor: SUZUKI YASUHARU
IPC: G01L19/10
Filed: 1979-03-28
Abstract: PURPOSE: To make it possible to perform a highly reliable pressure measurement by which vibrations including earthquake, pulsating pressure and impact pressure are corrected by providing an  auxiliary sector transmitting only the displacement corresponding to a specific pressure by a vibration proof device at a pressure gage of a Bourdon tube type or the like to control the displacement  of a main sector.  
     CONSTITUTION: The displacement corresponding to the pressure from a Bourdon tube pressure  receiving part 1' is transmitted through a pressure receiving part B to a main sector 3, and further  to an auxiliary sector 13 by way of a vibration  proof device 15 formed by a cylinder filled at its  inner part with oil and a pressure receiving point E. The displacement due to a slow pressure  fluctuationis is not transmitted to the sector 13 because it is absorbed by the device 15 but only  rapid displacement is transmitted thereto. By the sector 13 a pinion of the sector 3, having the  radius of pitch circle m which is equal to (l 2 /l 1 )×L 1  rotates, and the rotation corresponding to  the rapid displacement of the sector 3 is offset. Thus, the highly reliable pressure measurement by  which vibrations including earthquake, pulsating pressure, and impact pressure are corrected is  performed. Here, l 1  and l 2  represent the distance between the auxiliary sector fulcrum and the  pinion, and that of the pressure receiving point and the pinion, and L 1 , the distance between the  main sector receiving part and the pinion flucrum.

IPC: E03C1/30
Filed: 1988-02-18
Abstract: PURPOSE:To provide a solid detergent for a domestic waste water pipe which is odorless and is excellent in detergency, handling properties, storage stability, etc., by molding components including a hypochlorite and an inorg. bromide as principal components into a powdery, granular or tablet form. CONSTITUTION:A solid detergent for a domestic waste water pipe is produced by blending together raw materials comprising a hypochlorite (e.g., calcium hypochlorite) and an inorg. bromide (e.g., sodium bromide) as principal components and molding the blend into a powdery, granular or tablet form. When this solid detergent is put into a domestic waste water pipe and an appropriate amt. of water is poured thereinto, the reaction as shown by the formula occurs, thereby forming sodium hypochlorite which is an active component for detergency. Thus, excellent detergency is exhibited. The detergency effect, storage stability, etc., can further be improved by adding an appropriate amt. of a solid alkaline agent (e.g., anhydrous sodium silicate) to the detergent.

Title: Automatic data bypass for removed/failed cdma channel unit
Inventor: UINSUTON DEBUIDEIAN
IPC: H04J13/10
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To remove an optional unit by allowing a channel unit to output a bypass output signal having accumulated coded data without losing coded data from other unit.

Filed: 1988-02-17
Abstract: PURPOSE:To eliminate the necessity of reversing and feeding a transfer sheet and to form images in its both sides rapidly without enlarging a device by fixing the image after transcribing them on both sides of the sheet. CONSTITUTION:A first image which is formed on a photosensitive body 5 is transcribed on a transfer belt 11 by a first transfer means 7 and a second image which is formed on the photosensitive body 5 is transcribed on the one side of the transfer sheet 20 by the first transfer means 7.

In this way, the images can be formed on both sides of the sheet 20 by transcribing the images on both sides of the sheet 20 and fixing them. Thus the images on both sides of one sheet can be formed rapidly and the device can be miniaturized by avoiding the necessity of reversing and feeding the transfer sheet 20 to put it.
