Title: Thin cadmium sulfide film and its formation
Inventor: ISOZAKI YASUTO
IPC: C23C18/12
Filed: 1985-12-19
Abstract: PURPOSE:To form a thin cadmium sulfide film without using a vacuum vessel by forming the layer of a mixture of an org. cadmium compound having a cadmium-sulfur bond with a specified dopant on a substrate and by thermally decomposing the mixture in an oxidizing atmosphere. CONSTITUTION:An org. cadmium compound having at least one internal cadmium-sulfur bond, e.g. cadmium laurylmercaptide is mixed with an org. metallic compound having one or more metal-sulfur bonds, e.g. indium octylmercaptide as a dopant. The mixture is dissolved in a solvent and applied to the substrate of alumina or the like. After the solvent is volatilized by drying, the mixture is thermally decomposed in an oxidizing atmosphere, e.g. in the air to form a thin cadmium sulfide film. This film may be baked in an inert atmosphere as required. By this method, the thin film of a large area can easily be produced.

IPC: H03F3/34
Filed: 1994-11-21
Abstract: PURPOSE: To provide a variable amplifier for obtaining an amplification gain proportional to a control voltage. CONSTITUTION: A first differential amplifier circuit 12 differentially amplifies a variable control voltage Vc and outputs two currents and a logarithmic compression circuit 11 outputs two signals for which the two currents from the first differential amplifier circuit 12 are logarithmically compressed. A second differential amplifier circuit 13 differentially amplifies the two signals from the logarithmic compression circuit 11 corresponding to the current of a current source I2 and outputs the two signals and an error amplifier 15 respectively controls the current sources Ie and I2 so as to let the error of the signal to which offsetting is applied in an offset circuit 14 and the other signal from the second differential amplifier circuit 13 be '0'.  Thus, a setting current Ie inversely proportional to the control voltage Vc is supplied to an amplification system and the gain is set inversely proportionally to the setting current Ie in the amplification system. As a result, the gain proportional to the control voltage Vc is obtained in the amplification system.

CONSTITUTION:When an embroidering frame 31 is moved in the direction +Y, a slide plate 37 and lever 39 are moved in the direction +Y by a back and forth feed motor 32 to move a Y feed claw 42 to a position opposed to a Y feed ratchet 41. Thus, a X feed claw 52 is retracted from a X feed ratchet 51. When a change-over lever 68 is then moved right by a left and right feed motor 60, a lever 39 is pivoted right about a fulcrum 37b and only a claw 42a for forward rotation of the claw 42 engages a claw portion 41a of the ratchet 41. Here, the motor 32 is operated to move the lever 39 through the plate 37 in the direction +Y. Thus, the claw 42a is rotated and the rotation thereof is transmitted to a pinion 44e so that a movable bed 45 together with a rack 46 is moved in the direction +Y. As a result, an embroidering frame arm 31 is moved through pins 45a, 45b in the direction +Y.

IPC: F01L1/34
Filed: 1993-11-16
Abstract: PURPOSE:To provide a valve-timing adjusting device in which a hydraulic piston can be stably maintained in a desired position. CONSTITUTION:The position of a hydraulic piston 8 for changing the phase (spark-advance amount) between a camshaft side member and a crankshaft side member is determined by the oil quantity to be supplied to a spark-advance side oil-pressure chamber 14 or to a spark-delay side oil-pressure chamber 12. The oil supply quantity to both the oil-pressure chambers 14, 12 is regulated by a control valve 10. The chamber 26 facing to the large-diameter part 24a of the end part on one side of the spool 24 of the control valve 10 and the chamber 36 facing to the large-diameter part 24d of the end part on the other side thereof are communicated with each other through an axial hole 24f and a radial hole 24g. Accordingly, the oil leaked, for instance, from an opening 23d to the chamber 26 passes through the radial hole 24g and the axial hole 24f and flows into the chamber 36. Thus, the pressure inside the chamber 26 and that inside the chamber 36 are equalized, so that the position of the spool 24 can be accurately, linearly controlled, and the hydraulic piston 8 can be stably maintained in a desired position, and intake/exhaust valves can be opened or closed at a proper timing.
