IPC: H01L21/306
Filed: 1987-08-26
Abstract: PURPOSE:To forcibly absorb dusts in an etchant to a silicon wafer and to prevent the dusts from adhering to the wafer to be etched by mounting the dust absorbing silicon wafer oppositely to the wafer to be etched. CONSTITUTION:Etchant 2 is filled in a treating tank 1, a silicon wafer 4 in which the surface of silicon is completely exposed and a carrier 3 on which wafers 5 to be etched are alternately mounted are dipped in the etchant 2 to be etched. The wafer 4 performs a role of absorbing dusts. Further, if a thin silicon piece 6 is floated on the surface of the etchant 2, the dusts floated on the surface of the etchant are attracted by the piece 6 when the piece 6 is separated from the liquid surface and the carrier 3 is raised from the etchant 2. Accordingly, even when the wafer 4 passes the surface of the etchant 2, it can prevent the dusts from readhering thereon.

Title: Fuel cell
Inventor: ANDOU SUEO

Filed: 1983-11-15
Abstract: PURPOSE:To achieve sufficient oscillation-preventing effect and dielectric performance by winding an insulating material around an oscillation-preventing pin which is attached to the center of a clamping plate installed over the cell stack and inserting said pin in the hole of a supporting frame fixed to the top wall of the tank. CONSTITUTION:An upwardly protruding oscillation-preventing pin 34 is attached to the center of a clamping plate 33 installed over a cell stack 9. An insulating material 35 having a high compression resistance is wound around the pin 34. A supporting frame 37 having a hole 36 is fixed to the top wall of a tank 21 by means of bolts or similar members and the above pin 34 is inserted in the hole 36. Because of the above constitution, even when the height of the cell stack 9 varies due to heat cycles produced during the operation of a fuel cell, the pin 34 can vertically move in the hole 35 without causing any unnatural force. Besides, since the tank 21 supports the horizontal load of the contents of the fuel cell, oscillation can be effectively prevented. In addition, a sufficient dielectric strength can be produced between the cell stack 9 and the tank 21.

Abstract: PURPOSE:To form a film of uniform composition and thickness on a wafer by connecting one end of a funnel-like gas exhaust tube, which has a wall extended toward a wafer mount from the other end, to a gas introduction port and making a plurality of passage holes in the wall of the gas exhaust tube. CONSTITUTION:A gas exhaust port 21 completely covers a wafer mount 13. The wall of a funnel-like section is extended at an angle of about 30 deg. and five rows of about 5X5mm square passage holes 22 are made in the wall of the tube, each row consisting of 10-12 holes at appropriate distances between the rows. Mixed gas is introduced through the gas introduction port 15 with the temperature of a wafer 17 kept. In this time, the mixed gas flows downwards in the gas exhaust tube 16 along its wall. When the mixed gas reaches the funnel-like section, it spreads along the wall and a part of reactive gas flowing along the wall runs out through the passage holes 22. Thereby friction with the wall is decreased.

Abstract: PURPOSE:To prevent unstable revolution of engine and the engine stop by increasingly controlling fuel supply when a value with respect to a variation rate of engine speed is smaller than a minus specified value, and a detected air-fuel ratio is leaner than a specified air-fuel ratio. CONSTITUTION:In an engine provided with a throttle valve 3 on the way of an intake pipe 2 and provided with a fuel injection valve 6 at the upstream side, a fuel injection valve 6 is drivingly controlled by an ECU 5 which inputs respective signals of an intake pressure sensor 8, a throttle sensor 4, an water temperature sensor 9, and crank angle sensor 10 and an O2 sensor 15. In this case, in the ECU 5, a value with respect to the variation of engine speed is calculated. When the variation rate of the engine speed is smaller than the minus specified variation rate, an an air-fuel ratio detected by the O2 sensor 15 is lean, fuel injected from the fuel injection valve 6 is increased. consequently, sudden decrease of the engine speed or the engine stop are prevented without overriching the air-duel ratio.
