Title: Cleaning device for fixing roller
Inventor: HARADA SHINICHI
IPC: G03G15/20
Filed: 1987-05-22
Abstract: PURPOSE:To enable cleaning operation matching with the actual dirt of a fixing roller by moving a cleaning member according to an arrival signal of the number of times of copying operation and an or a jam frequency at a fixation part which reaches a prescribed value earlier. CONSTITUTION:It is indeterminate that either of the number of times of copying operation and the number of times of jam occurrence reaches a predetermined value earlier, but the cleaning member 32 is moved according to the output of the number of times which reaches the value ealier. Namely, a new part of the cleaning member 32 strikes on a fixation roller 24, which rotates to come into slide contact with the cleaning member 32, thereby sweeping dirt on the fixation roller 24. Thus, if the fixation roller 24 becomes dirty by more than a prescribed level, it is cleaned without fail, so no offset transfer paper is generated and invariably excellent image quality is obtained.

Title: Pin-diode driver circuit
Inventor: SHIMODA HIROMI
IPC: H03H7/25
Filed: 1984-06-20
Abstract: PURPOSE:To improve the precision of control over the quantity of attenuation by controlling and driving a pin-diode as an attenuating element in current mode and also suppressing and controlling a control current in current mode. CONSTITUTION:A control voltage Vi from a terminal 109 is converted into the control current through the impedance element Rc (consisting of resistances R11 and R12 and a Zener diode X5). The pin-diode is controlled and driven in current mode with this control current to control the bias voltage of the pin-diode X4 of a variable attenuating circuit. Therefore, the attenuation quantity control characteristic to the control voltage Vi is nearly linear in the range where the control voltage Vi is 0-Vb (specific value) and changes into a characteristic which increases in variation rate to Vi about the voltage Vb as a boundary point. Consequently, the precision of control over the quantity of attenuation is improved.

Title: Information writing and reading method and device
Inventor: MARINUSU YOHANESU BERUNARUDASU
IPC: G06F3/06
Filed: 1981-08-14
Abstract: A description is given of a method and an associated device for the writing and reading of information into and from a record carrier body. The record carrier body is preferably made of a radiation-sensitive medium and comprises a servo track. The information is written in consecutively arranged sectors and is read directly after writing for the purpose of verification. A vector address VA(n) is added to the amount of information to be written in a sector. A vector address of this kind indicates a previously inscribed sector of the record carrier body, said previously inscribed sector having the property that the information has been correctly written therein. The added vector address enables the transfer of only the correctly written information to a user when the written information is read. The use of so-called <<interleaving>> during the inscribing of information in the record carrier body protects the information written against an error burst.

IPC: E02F9/22
Filed: 1986-06-03
Abstract: PURPOSE:To enable soil to be excavated and discharged quickly, by providing a hydraulic circuit for connecting a rotary motor to a change-over valve for swing, with a speed-regulating valve for enabling the opening to be freely set. CONSTITUTION:When the set pressure of a pilot pressure-reducing valve 12 is set to be 0, then the pressure of the pilot duct line 11 of a pilot hydraulic circuit comes to approx. 0. A speed-regulating valve 9 is put at a position 9a for full admission by the pressure of a spring 10, and the inflow of pressure oil fed from a first hydraulic pump 1 to a rotary motor 8 is not limited. In case that a boom is quickly taken to a high position, when the set pressure of the pressure-reducing valve 12 is heightened, then pilot pressure is worked on the regulating valve 9 through the duct line 11, and the opening is narrowed down, and the inflow of the pressure oil to the motor 8 is suppressed. Accordingly, the limited pressure oil is conducted to the increased speed circuit of the boom by the limited component, and the rising speed of the boom is increased.

Title: Switching device
Inventor: TAKEMOTO TOYOKI
IPC: H01L39/22
Filed: 1987-05-25
Abstract: PURPOSE:To provide a switching device adapted for a memory cell which can be easily manufactured with a large capacity by forming a cooling semiconductor gate through an insulator on a superconductor on which electrodes are disposed at both ends, reducing the temperature of the face of the gate at a superconductor side to vary the temperature of the superconductor, thereby altering the conductivity of the superconductor. CONSTITUTION:When a word line 1 becomes a potential VDD, a potential difference of VDD is applied to a connecting material of both the ends of a semiconductor gate 4, and the lower surface of the gate 4 absorbs heat. Thus, the lower surface is cooled, and a high temperature superconductor 6 is cooled through an insulator film 5. When the temperature of the superconductor 6 falls from a T2 to a T1, its resistance is abruptly reduced from a very large resistance R to a resistance '0'. The temperature of the superconductor 6 drops from a critical temperature T0 to the temperature T1 lower than the T0 by this property, and the potentials of a bit line 2 and a capacity 3 are electrically conducted. Then, when the line 1 is set to a ground potential, the heat absorbing action of the lower surface of the gate 4 is stopped, the superconductor 6 becomes higher than the critical temperature, its resistance rises, and the line 2 and the capacity are insulated. This operation is repeated to operate as a storage element.

Title: Method and device for shaking out sand from aluminum casting prepared in sand core
Inventor: NAKAMURA KIYOSHI
IPC: B22D29/00
Filed: 1979-10-03
Abstract: PURPOSE: To perform sand shaking out effectively and perfectly by heating sand mold core aluminum castings to a high temperature then intermittently and repeatedly blowing high-pressure air.  
     CONSTITUTION: A heating burner 10 is burned and a hot air fan 11 is driven to feed hot wind into a heating-drying facility 1 as shown by the arrow B. After the chamber inside has attained a predetermined high temperature, sand mold core aluminum castings 4 are carried into respective facilities 1, 2, 3 by moving an intermittent feed type conveyor 5. Respective shutters 6, 7 are closed to shut off the atmospheric air, whereby the castings 4 are heated to a high temperature together with the core sand. Next, the catings 4 in a high temperature state are intermittently blown several times with the high-pressure air spouted from the nozzles 20 of a high-pressure air supply path 12, in the high-pressure air blowing facility 2. Thus, the sand which has been weakened of binding force by heating is perfectly removed. Next, the castings 4 are sent into the cooling facility 3 and the shutters 7, 8 are closed so that they are cooled by the air through an air cooling fan 13. The exhaust air is completely released into the atmosphere through a dust remover 15.

Inventor: SAKAGAMI TADASHI
IPC: F24H9/20
Filed: 1978-10-18
Abstract: PURPOSE: To provide an automatic temperature controlling apparatus, capable of keeping the hot water at a proper temperature, by employing an arrangement in which main body of a thermo-valve is positioned in a gas supply passage for supplying gas to the gas burner and a heat-sensitive portion of the thermo-valve is positioned at the outlet of a water heating pipe to be heated by the gas burner, so that the pipe heating rate is changed in response to the temperature change of hot water.  
     CONSTITUTION: Hot water from water heating pipe 20 flows through water collecting tank 24 and pipe 23 and issues to the outside from shower head 26 or hot-water supplying pipe 28. Here, heating portion 32 constituting a heat-sensitive portion A of thermo-valve 12 is heated or cooled by the hot water flowing in the tank 24, which causes resultantly expansion or contraction of bellows 32 which is formed integrally with the heating portion 32. Through expansion and contraction of bellows 32 and by the function of compression springs 39, 40 provided in valve portion B of thermo-valve 12 and gas pressure acted to valve body 38 in the valve portion B, the valve body 38 is moved toward and away from valve seat 37. As the result, clearance between the valve body 38 and valve seat 37 is changed and thus amount of gas supplied to a second main gas burner 5 is controlled, so that quantity of heat supplied to water heating pipe 20 is changed. Thus, temperature of hot water flowing to the downstream side of tank 24 can be kept constant.
