Title: Abnormal sheet material detector in sheet material processor
Inventor: OONISHI TETSUO
IPC: B65H7/12
Filed: 1980-02-23
Abstract: PURPOSE: To prevent a malfunction caused by a change in the feed rate of sheet material and in the drift of a circuit by using the detection value of the n-th sheet material as a reference value to be compared with that of the (n+1)-th sheet material.  
     CONSTITUTION: When the front edge of the second sheet material S 2  arrives between a radiation light emitting diode 42 and a photodiode 44, a storage circuit 56a sample-holds the detection value output e 02  of an amplification circuit 4 using the sample pulses from a timing circuit 52a. On the other hand, since the signals for the first sheet material are not entered into a timing circuit 58, a storage circuit 57a continues holding the stored detection value output e 01  of the first sheet material. Consequently, a comparator circuit 54a compares the output e 02 ' of the amplification circuit 4 with the output e 01  when the rear edge of the sheet material S 2  passes through the detectors 42 and 44. Subsequently, the output e 02  of the storage circuit 56a is transferred to the storage circuit 57a and is used as a reference value.

Title: Manufacture of thermoplastic resin composition
Inventor: URA TOMOKATSU
IPC: C08L67/00
Filed: 1998-02-03
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a thermoplastic resin composition by which it is easy to add fine silica particles treated to have hydrophobic properties to thermoplastic resin and obtain a resin composition whose particle dispersibility is excellent. SOLUTION: Fine silica particles with the surface treated to have hydrophobic properties are dispersed in a mixture of water and/or a polar organic compound whose boiling point is at most, the melt point of the thermoplastic resin and a dispersant, as a dispersion. And this dispersion is added to and kneaded with a thermoplastic resin using a vent double-screw kneading extrusion machine. Consequently, the fine silica particles contained in the thermoplastic resin composition thus obtained are uniformly dispersed without becoming flocculated. Therefore, when the composition is stretched into a film, it is possible to obtain a uniformly uneven surface free from coarse projections. In addition, this film shows outstanding easy-smoothness and and wear resistance.

Title: Large capacity disk file device
Inventor: YAMASHITA TORU
IPC: G11B17/26
Filed: 1989-02-02
Abstract: PURPOSE:To shorten the time required for control of vibrations of a mobile member and at the same time to reduce the vibrations at stop of the mobile member by securing such a constitution where the moving speed of the mobile member is slowed down before a position sensor detects the stop position of the mobile member and then the sensor detects the stop position of the mobile member at the decelerated speed to stop the drive of a stepping motor. CONSTITUTION:The moving speed of a mobile member is slowed down to one to several portions of the maximum self-start speed of a stepping motor 19 before the stop position of the mobile member is detected by a position sensor 53. Then several multiples of time decelerating speed is secured from the cycle of the natural vibration of a vibration system consisting of the mass of the mobile member, the elasticity of a belt 17, etc. Then the movement of the mobile member is controlled via a control part so that the sensor 53 detects the position of the mobile member. Thus the time required for control of vibrations of the mobile member can be shortened and at the same time the vibrations can be reduced at stop of the mobile member. Then the mobile member is surely positioned at a high speed.

IPC: G03G15/00
Filed: 1993-01-19
Abstract: PURPOSE:To allow heat generated from a heat source to be hardly transmitted to housed toner by providing ventilation fins generating an air flow for diffusing the heat retained around the outside circumferential part of a toner replenishment container. CONSTITUTION:The ventilation fins generating the air flow for diffusing the heat retained around the outside circumferential part of the toner replenishment container 1 are integrated in a gear part 1A being a driven part when the container 1 is driven to be rotated. When the container 1 is driven to be rotated by a driving device at the replenishing time of toner, the air flow is generated toward a fixing device 5 side from the toner replenishment unit 3 side of the container 1 by the actuation of the ventilation fins. That means, air enters a void 19 between the respective fins and flows around the outside circumferential part of the container 1 along the axial direction of the container 1. Thus, the heat retained around the container 1 is diffused and the heat is hardly transmitted to the toner housed in the container 1.
