Patent JP-H02217648-A (JP)
Title: Manufacture of flywheel
Inventor: OMI RYUJI
IPC: F16F15/30
Filed: 1989-02-17
Abstract: PURPOSE:To prevent rupture of a flywheel by providing a corner roundness for the bottom peripheral edge of a counter-bored recess, in which the end of a crank shaft is fitted, and subjecting the corner roundness to surface hardening treatment. CONSTITUTION:In a flywheel 1, corner roundness 1e is provided throughout the circumference of the bottom periphery 1c, which forms boundary between a counter-bored recess 1a and a rising part 1b. This corner roundness 1e is subjected to surface hardening treatment, for ex. shot-peening or high frequency quenching. The end 2a of a crank shaft is fitted in this recess 1a. This accomplishes high strength without generating concentrated load at the corner roundness, and thereby rupture of flywheel likely to be initiated at the bottom periphery will be avoided.

Abstract: PURPOSE:To stabilize an element characteristic, and improve reliability by lengthening the service life or the like by forming an (n<+>) layer coming into contact with a vacuum and a (p<+>) layer under it, and impressing inverse bias. CONSTITUTION:A (p<+>) layer 5 is formed on a (p) type Si board 6 by diffusion, and next, an (n<+>) layer 4 is formed by ion implantation or the like. In this stage, an electrode 7 is attached over the whole wafer reverse surface of the board 6, and a fine mesh-like electrode 3 is installed on a layer 4 surface. An element cut out of a wafer is put in a vacuum, and inverse bias is impressed through high resistance, a material by applying a phosphor film 10 onto glass 8 having a transparent conductive film 9 is arranged as an anode, and prescribed electric potential is impressed on the conductive film 9. In this case, when a valence electron in a (p<+>) area is implanted in an (n<+>) area by a tunnel effect by impressing inverse bias voltage on (p<+>)-(n<+>) junction, an energy loss in an (n<+>) semiconductor of a hot electron is reduced, and energy to emit an electron in an effective vacuum is reduced, and it can be easily emitted in a vacuum from a semiconductor surface.

Abstract: PURPOSE:To prevent the fluctuation of a negative polarity voltage, by detecting the fluctuation of an output voltage and controlling a positive polarity voltage with negative feedback, in a circuit outputting a negative polarity power supply through the rectification of an output of an oscillation circuit applied with the positive polarity power supply. CONSTITUTION:An output of an oscillation circuit 30 consisting of logical ICs 6-8 and feedback circuits 1-5 and to a terminal 20 of which a positive polarity voltage is supplied is rectified at a rectification circuit 31 and a negative pollarity voltage is outputted t a terminal 31. The output of the circuit 31 is connected to a positive polarity power supply 19 via a series connection of resistors 16 and 17, and the connecting point of the resistors 16 and 17 is connected to the base of a transistor (TR) 18. The collector of the TR18 is connected to the power supply 19 and the emitter is connected to the terminal 20. If an output voltage at a terminal 31 changes to positive direction, the base of the TR18 also charges to the positive direction, the voltage at the power supply terminal 20 of the circuit 30 changes to the positive direction, a voltage at the terminal 31 changes to negtive polarity and the fluctuation in the negative polarity voltage can be suppressed. Similarly, the fluctuation in the negative polarity voltage output can be suppressed in case of opposite change.

Title: Paper sheet separating device
Inventor: YOSHIDA KAZUJI
IPC: B65H3/48
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of overlap feed and remove jammed paper sheets easily even with the generation of a jam by providing a plurality of resistance means for making resistance act upon paper sheets, in a paper sheet conveying direction. SOLUTION: A separating roller 4 is fitted being pressed to a chamber 3 by a spring means so as to be movable corresponding to the thickness of a delivered letter. A plurality of separating rollers are provided in a conveying direction. Accordingly, at the time of separatively delivering other paper sheets different in thickness, even though the paper sheet collides with one separating roller 4 to oscillate this separating roller 4, the other separating roller 4 in a different position in the conveying direction does not oscillate, so that resistance can act upon the delivered paper sheet. With a plurality of separating rollers thus arranged in the paper sheet conveying direction, resistance can positively act upon the paper sheets so as to be able to reduce overlap feed at the time of delivery.
