Patent JP-S62274920-A (JP)
Title: Current controller
Inventor: TSUNASHIMA HIROSHI
IPC: H03K17/60
Filed: 1986-05-23
Abstract: PURPOSE:To drive a large current with a simple circuit constitution by providing an IC using an FET which outputs an output binary signal, a bipolar transistor structure part, and a current circuit part to be controlled and driving and controlling the operating current in the current circuit part to be controlled by a control input signal. CONSTITUTION:An IC 115 using the FET has a totem pole output form and outputs an output binary signal 113 which is in the high logical level or the low logical level in accordance with the binary of a control input signal 111. The output binary signal 113 is led to the base electrode of a PNP (or NPN) transistor structure part 117, and this part 117 is made non-conductive if the signal 113 is in the high logical level, and the part 117 is made conductive if the signal 113 is in the low logical level. A current flows to a current circuit 119 to be controlled when the transistor strucure part 117 is turned on. Consequently, the operating current in the current circuit part 119 to be controlled is driven and controlled by the control input signal 111 as the whole. Thus, a private IC is not used to simplify the circuit constitution.

Abstract: PURPOSE:To reduce friction at the time of pit wall-surface disintegration preventive excavation and the cost of equipment by forming the blade nose-section of a detachable agitating blade projected from a rod in blade length approximately brought into contact with the inwall of a pit and forming the agitating blade in a tabular shape parallel with the longitudinal direction of the rod. CONSTITUTION:Tabular agitating blades 5 in blade length, noses of which are positioned at sections slightly inner than the inwall surface of an excavating pit 3, are shaped. A plurality of the blades 5 are installed detachably at regular intervals to a boring rod 1, at a lower end of which an excavating blade 4 is formed, while tabular surfaces are shaped in parallel in the longitudinal direction of the rod 1. The detachable sections of the blades 5 are formed of lower projecting pieces 9 supporting the lower end faces of collar-shaped mounting plates set up to the base sections of the blades 5, guide groove pieces 10, to which the mounting plates are inserted, and upper flanges 18 for engaging the agitating blades. Accordingly, the pit can be excavated while the blade ends preventing the disintegration of the pit inwall, and contact surfaces are reduced, thus turning the blades in low friction, then curtailing the cost of equipment by exchanging the blades.

Title: Apparatus for controlling recirculation of exhaust gas in air-fuel ratio control device for internal combustion engine
Inventor: OOTSUKA KAZUO
IPC: F02M25/07
Filed: 1980-08-28
Abstract: PURPOSE: To lower the manufacture costs of an exhaust-gas recirculating system, by simplifying the construction of a control unit for the exhaust-gas recirculating system through employment of an arrangement in which sensors for detecting the absolute pressure and engine temperature are used also for detecting conditions of interrupting recirculation of exhaust gas during low-load operation of the engine or when the engine temperature is low.  
     CONSTITUTION: A valve 35 for controlling recirculation of exhaust gas is provided at a portion of an exhaust-gas recirculating passage 34 which communicates the exhaust system and intake system of an internal combustion engine 1 to each other. Here, arrangement is such that the valve 35 is opened and closed by negative pressure introduced into a vacuum chamber 35e of the valve 35 via a negative-pressure passage 36 and that the passage 36 is opened and closed by a solenoid valve 37. Recirculation of exhaust gas and air-fuel ratio are controlled by controlling a coil 37c of the solneoid valve 37 and a pulse motor 13 of an air-fuel ratio control valve 9 by an ECU20. Here, the ECU20 is designed to close the negative-pressure passage 36 by supplying current to the coil 37c and to close the valve 35 by introducing atmospheric pressure into the vacuum chamber 35e when both of the outputs of an absolute-pressure sensor 31 and a temperature sensor 33 become lower than respective set values.

Patent JP-S5645035-A (JP)
Title: Preparation of semiconductor-supporting electrode
Inventor: OONUKI HITOSHI
IPC: H01L21/52
Filed: 1979-09-19
Abstract: PURPOSE:To obtain a semiconductor-supporting electrode having small and uniform thermal expansion coefficient by alternately piling a composite material of Cu and spiral C fibers and Cu plates to form one body so that the disorder of the fibers in the lateral and longitudinal directions can be prevented. CONSTITUTION:When the C in a Cu-C fiber is made above 50vol%, a bundle of the fibers can have a fairly even Cu plated layer, and therefore the bundle can be coiled uniformly, so that the undulation of the C fibers is prevented. Moreover, hot- pressing several coiled Cu-C fibers sandwiching Cu plates permits the Cu plates to prevent the deformation of the fibers. Consequently, the contraction coefficient decreases, and also the longitudinal disorder of the fibers largely reduces. In addition, the electrical conductivity can be adjusted by increasing or decreasing the volume of the Cu. The constitution permits an electrode having a uniform thermal expansion coefficient to be formed at a large yield.

IPC: C08J7/00
Filed: 1983-06-29
Abstract: PURPOSE:To improve spectral transmission characteristic by treating a resin film with a bath contg. a pH adjuster in the stage of dyeing said film with a cyan acid dye. CONSTITUTION:A dyeing bath or rinsing bath contg. a pH adjuster consisting of a non-volatile org. base or non-volatile acid is used in a process for dipping a hardened resin film of a microcolor filter for a color image pickup device and coloring said film. The pH adjuster has >=150 deg.C b.p. and remains in the film even after drying. Said adjuster is exeamplified by amino alcohol, pyridine, diamine, etc. A cyan acid dye (phthalocyanine acid dye) involves coloring in an acidic dye but the environmental pH in the film is made acidic and the spectral transmission characteristic thereof decreases. Such decrease is prevented by using the bath contg. the pH adjuster.
