Title: Printer
Inventor: SAITO HIDEO
IPC: B41J1/24
Filed: 1986-10-27
Abstract: PURPOSE:To enable easy replacement of a type wheel, by providing on a mount base for a type selection motor, a type wheel presser for pressing the type wheel positioned at a position suitable for printing, from the side opposite to a motor shaft of the type selection motor, in conjunction with an operation of a driving means for the mount base. CONSTITUTION:When a driving motor 9 is rotated clockwise, a type wheel 4 is vertically shifted together with a vertically movable member 22 through the functions of a pair of shift arms 12, 12' and a pair of engaging bodies 21, 21'. After the type wheel 4 is thus shifted, a motor mount base 13 is moved in the direction of a platen by a cam of a cam gear 11 through a support plates 16, 16' and a connecting rod 15. This movement is accompanied by the insertion of a motor shaft 23 into a shaft hole in the type wheel 4, and a wheel presser 18 having bee restrained by a pin 19 is made to be freely rotatable. The wheel presser 18 is energized by a leaf spring 20 to press a ball-shaped part 4' of the type wheel, thereby mounting the type wheel onto the motor shaft 23. Thus, it is possible to completely eliminate elastic resistances at the time of mounting and detaching the type wheel from the motor shaft.

Title: Overvoltage breakage prevention circuit for gto thyrister
Inventor: SAOTOME HIDEO
IPC: H03K17/73
Filed: 1985-11-14
Abstract: PURPOSE:To prevent breakage due to an excessive voltage by providing an overvoltage detection circuit, connecting a quick semiconductor switch to a snubber capacitor in parallel and turning on said switch with the aid of an output from the overvoltage detection circuit so as to discharge the charge of the snubber capacitor. CONSTITUTION:The overvoltage detection circuit 6 is provided which detects an overvoltage and acts on a gate drive circuit to output an on signal. The quick semiconductor switch is connected to the snubber capacitor 3 in parallel and turned on by the output from the overvoltage detection circuit so as to discharge. During the turn-on delay time of a GTO thyrister 1, its anode voltage maintains below its peak non-repetition voltage. Thus with the anode voltage of the GTO thyrister after its delay time set below said peak non-repetition voltage, the GTO thyrister can be securely protected from breakage due to an excessive voltage.

Title: Manufacture of quantum thin line structure
Inventor: KATSUYAMA TOSHIO
IPC: H01L29/812
Filed: 1986-10-29
Abstract: PURPOSE:To manufacture quantum thin line structure, by disposing layered materials as masks on a surface of a semiconductor thin film and implanting ions from above so as to disorder a prescribed region of the laminated semiconductor thin films of quantum well structure. CONSTITUTION:GaAs and AlGaAs layers are alternately laminated 5 thinly on a GaAs substrate 4 to form multi-quantum well structure. Next, when a graphite film 3 is melded thinly thereon and it is mounted on the thin films of quantum well structure so that its C axis runs parallel with the thin film 3, channeling can be formed when ions of Si or the like are implanted into the thin film. Successively, when ions of Si or the like are implanted vertically into the thin film, Si ion implanted layers are formed in striped shapes at narrow intervals on the thin films 2. Finally, when the thin films 2 are processed under a proper condition of heat treatment, only the striped region where Si is implanted is disordered because Si disorders the quantum well structure. Hence, a quantum thin line structure can be manufactured.

Title: Friction material and its manufacture
Inventor: KAWABATA MASATAKA
IPC: C08J5/14
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To provide a friction material which uses a paper-form base material and secures a large friction coefficient by heightening the strength and enhancing the followup performance after another member as the mating party. SOLUTION: The entangling density of fibers of the friction surface to make friction with the mating party is made smaller than the fixed surface contacted fast with a core piece. A napped fiber layer 10 softer than the fixed surface side 200 is formed on the friction surface 100, which therefore excels in the followup performance after the mating party to secure a wide contacting area therewith. Accordingly a large friction coefficient is ensured.

Abstract: PROBLEM TO BE SOLVED: To determine whether a flow path forming member and a valve body are acceptable from a flow rate value by making gas flow in an oil flow path while the valve body and the flow path forming member are in a predetermined positional relation and by measuring a gas flow rate. SOLUTION: While a spool valve 2 is housed inside a rod piston 4, the piston 4 is positioned at a predetermined position by a side masking member 22, a lower masking member 23, and an upper masking member 21 and also an oil flow path is shielded from outside. Then the valve 2 is held by an upper bar 25 and a lower bar 27 for fixing a spool from upward and downward to be positioned at an original position with respect to the piston 4. Then air of a constant pressure is supplied from a supply part of an air supply mechanism to the oil flow path of the piston 4. Thus air flowing from a lateral through hole 4y into a hollow 4k passes through between an outer peripheral face of the valve 2 and an inner peripheral face of the piston 4 to flow downward and is led from an exhaust path 23r of the member 23 to a measurement part. Then an air amount flowing in the oil flow path is measured.
