Inventor: KIN TOUGEN
IPC: H01L27/108
Filed: 1990-07-10
Abstract: PURPOSE: To prevent leak current between trenches by combining a layered capacitor structure and a trench capacitor structure alternately to fabricate a capacitor while adjusting the thickness of silicon and the depth of trench respectively. CONSTITUTION: Only a part for fabricating a trench capacitor is defined from a layer where an isolation oxide 7 is deposited on a defined gate 4 and a trench 2 is made. A thick silicon 10 is then deposited and a contact window 1 is opened at a part for fabricating a multilayer capacitor. Subsequently, only a capacitor region is defined on the thick silicon and a silicon 11 for storage node is deposited, subjected to doping and defined. Finally, a polysilicon 13 for the plate is deposited while being applied with a thin dielectric 12 for the capacitor. This structure can block leakage current between trenches.

Title: Output control device of heat wire sensor
Inventor: MATSUOKA HIROKI
IPC: G01F1/696
Filed: 1984-09-03
Abstract: PURPOSE:To control a fuel jet quantity with a high accuracy, to prevent a delay of a rise of a revolving speed of an engine, and to reduce an exhaust quantity of an exhaust gas by constituting a titled device so that an output of a heat wire sensor is smoothed appropriately even in case of a transient state of the engine. CONSTITUTION:A capacity of a suction system of a throttle valve 3, a surge tank 4, a suction port 5, etc. exists between a heat wire sensor 2 and a combustion chamber 9. Therefore, when the throttle valve 3 is changed quickly from full-closing to full-opening, an air quantity D absorbed into the combustion chamber 9 and an air quantity C detected at a position of the heat wire sensor 2 do not coincide with each other. On the other hand, the quantity of a fuel jetted into the combustion chamber 9 is determined in accordance with a virtual absorbed air quantity C, therefore, it is excessive with respect to the air quantity D absorbed into the combustion chamber actually. Therefore, in case of a state that a variation rate F of an opening of the throttle valve 3 has exceeded a prescribed value T, overrich or overlean is prevented by smoothing an output of the heat wire sensor 2, and at the transient time, an exhaust quantity of an exhaust gas is reduced and a revolving speed rises smoothly.

Title: Method for controlling electric power for double-solenoid electric impact tool
Inventor: SHIN-TEN CHEN
IPC: B25D11/06
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To obtain enough electric power by controlling the position of a hammer when the first solenoid is switched to the second solenoid for increasing the electric power of an impact tool. SOLUTION: When the left end of a hammer 10 is moved to the position between a point C and a point T, the point C is positioned to the left side of the point T so that the current does not flow a first solenoid L1, which does not apply power on the hammer 10, but the current flows through a second solenoid L2. Thereafter when the hammer 10 is moved to the position between the point T and the point C, the point C is moved to the right side of the point C so that the second solenoid is not energized as before and the power is not applied on the hammer 10. In the meantime, the current flowing through the first solenoid L1 is still present, but the right side of the hammer 10 exceeds the first solenoid L1. Therefore, the power, applied on the hammer 10 by the first solenoid L1, is greatly decreased, and the hammer 10 is moved to advance rearward.

Filed: 1989-07-14
Abstract: PURPOSE:To economically produce a curved enameled panel having a complicated rugged pattern by superposing a rubber sheet on the protrusion side of a metallic sheet, bending the sheet and then coating the sheet with an enamel layer. CONSTITUTION:A flat base material consisting of an enameled steel sheet is press-worked to obtain a metallic sheet 1 having a protrusion 2 on the surface 1a. A rubber sheet 4 having a thickness greater than the height (h) of the protrusion 2 is superposed on the surface of the sheet 1 on its protrusion side. An escape hole into which the protrusion 2 is to be inserted is bored in the rubber sheet 4, or the sheet can be closely attached to the surface of the metallic sheet 1 with a magnet layer, an adhesive, etc. The laminate of the metallic sheet 1 and rubber sheet 4 is passed through a bending roll 8 consisting of pinch rollers 5 and 6 and bent through a curved surface adjusting roller 7. The rubber sheet 4 is then removed, and the metallic sheet 1 is glazed and burnt to form an enamel layer. Consequently, a curved enameled panel having a variegated pattern and an excellent appearance is obtained practically irrespective of the shape and arrangement of the protrusion.
