Title: Protector for electrophotographic sensitive body
Inventor: YAMAZAKI KOJI
IPC: G03G21/00
Filed: 1986-05-28
Abstract: PURPOSE:To prevent the flawing of a photosensitive layer by using a protector formed by installing a cushion material onto the inside peripheral face of a cylindrical resin film provided with creases for folding to a flat plate shape. CONSTITUTION:Resins such as PE, PP and PE terephthalate having good slipperiness are used as the material to form the cylindrical resin film 2-1. A fibrous material is preferable as the cushion material 2-2 as such material wipes off and adsorbs the toners, etc., sticking to the photosensitive layer. Materials formed of acryl and acetate into the fibrous state or cotton, etc., are more preferable. The discharge breakdown of the photosensitive occurring in the generation of static electricity at the time of the removal of the protector from the photosensitive body is prevented if such material 2-2 is subjected to an antistatic treatment. The flawing of the photosensitive layer surface of the photosensitive layer at the time of putting the photosensitive body into and out of the device is obviated by using the above-mentioned protector 2.

Patent JP-H07332575-A (JP)
Title: Pipeline vibration control device
Inventor: ASAKURA DAISUKE
IPC: F16F15/02
Filed: 1994-06-02
Abstract: PURPOSE:To enable the sufficient suppression of coupled vibration of a pipeline and in its turn prevent the soundness of the pipeline from being impaired by constraining the external wall of the pipeline by a cylindrical vibration damping member, and forming the axial length of the cylindrical vibration damping member to be longer than the wavelength of the axial mode of the coupled vibration. CONSTITUTION:The coupled vibration of the vibration mode of a pipeline wall and higher-order acoustic mode of a fluid in a pipeline has circumferential, radial and axial modes. Out of these modes, the circumferential and radial modes are suppresed by constraining the external wall of the pipeline 3 by a cylindrical vibration damping member 10. On the other hand, the wavelength of the axial mode has a characteristic uniquely determined by the diameter and length of the pipeline 3 and the acoustic velocity of the fluid. The axial mode can be therefore suppressed sufficiently if the axial length of the cylindrical vibration damping member 10 is formed longer than the wavelength of the axial mode of the coupled vibration.

Title: Controlling method for temperature of warm air room heater
Inventor: YAMAZAKI YASUSHI
IPC: F23N5/20
Filed: 1991-04-23
Abstract: PURPOSE:To made a temperature in a room uniform and to eliminate unpleasant feeling due to cold air by so controlling as to intermittently operate a fan at a low output until reburning occurs after a combustion is once stopped when a room temperature becomes higher by a predetermined temperature or higher than a set temperature. CONSTITUTION:When an operation switch 11 is closed and a room heating temperature is set by a temperature set and timer set button 13, a microcomputer 5 first starts an operation of a maximum heat generation. It monitors that a room temperature R becomes a high temperature switching temperature higher by a predetermined temperature (a) (e.g. 1 deg.C) than a set temperature S, and switches to an operation of a minimum heat generation when it becomes the temperature. If the temperature R further rises even after it is switched to the minimum heat generation, a combustion is stopped, and an operating state for once stopping rotation of a fan 1 and an operating state for rotating the fan at a minimum value are intermittently conducted. Thereafter, when the temperature R becomes lower by a predetermined temperature (b) than the temperature S, it is again switched to the operation of the maximum heat generation.

Title: Pulse train conversion circuit for rotary encoder
Inventor: FUMEI FUMEI
IPC: H02P29/00
Filed: 1991-04-24
Abstract: PURPOSE:To easily remove pulse noise by detecting the pulse noise to remove from a pulse train a pulse having timing that coincides with a pulse due to noise. CONSTITUTION:Pulses of phases A and B mixed with pulse noises are inputted into a D-flip flop F1 and F11. An output of the F1 is inverted to a L level from an H level while an output of the F11 is inverted to the H level from the L level and the pulses via F2 and F12 are supplied to NOR gates H3 and H4 and an NAND gate G15 of a noise detection circuit 7 via NAND gates G1 and G2 and G7 and G8. The gate G15 detects pulses attributed to noises alone to be outputted to NAND gates G13 and G14. On the other hand, NOR gates H1 and H2 output pulses containing the direction of a motor rotation and speed information and the pulses attributed to the noises. When the motor rotates normally, the gate G14 is kept at the L level to generate no pulse. The gate G13 cancels the pulses attributed to the noise coinciding therewith in timing thereby outputting a pulse train alone owing to the pulses of phases A and B.

Abstract: PURPOSE:To provide a push-button switch for the operation of a press, by which safety of a work is secured, and also, a degree of fatigue of a worker is reduced even in the case of the work extending over many hours, and moreover, cleaning of intruded foreign matter is facilitated, or an intrusion of foreign matter can be prevented. CONSTITUTION:The outside periphery of a push-button 5 is separated, and it is surrounded by a guard ring 7 having the upper face operating part being higher than the upper face in the upper limit position of this push-button 5, therefore, even if an object drops down from the upper part, the push-button 5 is not depressed. Also, in the front side part and/or the rear side part of the guard ring 5, an opening part 9 being a little larger than the palm is provided, therefore, a worker can operate the push-button moderately by putting a hand H in a position of the opening part 9 and depressing the push-button 5. Moreover, since the whole of a push-button switch 1 is covered with a rubber cover (flesible sealing member), an intrusion of foreign matter and refuse is prevented and a misoperation can be prevented.

Abstract: PURPOSE:To save energy of a ship by circulating hot water heated at a cooler to heat the equipment to be heated. CONSTITUTION:A fresh water fed by a pump 10 to a fresh water cooler 2 provided at the scavenging cooler 4 of a main engine 1 is heated by cooling the engine 1, and heats an equipment 5 to be heated when passing therethrough.
