Title: Disc brake
Inventor: MIYAKE KATSUYA
IPC: F16D55/224
Filed: 1982-10-29
Abstract: PURPOSE:To reduce frequency of noise generation at the time of braking by inserting a compression spring made of shape memory alloy in a recession of a part near the outer periphery of a rotor on the internal side face of a caliper pawl and elastically pressing a part near the outer periphery of a pad towards a rotor only when the temperature is high. CONSTITUTION:A compression spring 6 made of shape memory alloy exhibits its configurations A and B under the normal temperature and the high temperature respectively. Such a compression spring 6 is used in a configuration inserted in a recession 7 formed on the upper internal side face of a caliper pawl 4a, and the internal side face of which is in contact with the back side of one pad 3. Since the compression spring 6 contained in the recession is short in its full length at the normal temperature, the pad 3 is not elastically pressed by said spring 6, however, when the temperature of the pad 3 is raised, the spring 6 is growing larger in its full length and elastically presses a part near the rotor outer periphery of the pad 3. This pressing force is larger on the outer peripheral side part of the rotor than the inner peripheral side part. Thus, generation of noise can be effectively prevented at a high temperature when the noise is easily generated during braking action.

Title: Method and device for removing scales
Inventor: AOYANAGI HIROHIDE
IPC: F23J3/00
Filed: 1986-08-12
Abstract: PURPOSE:To make it possible to easily remove scales from a burner by mounting burnable botanical solid particles such as husks, seeds and the like of plants, having a relative small repulsion coefficients, on a high speed airstream and ejecting them onto the surface of objects of cleaning. CONSTITUTION:The action of a scale remove 1 is taken in such a manner that n operating air changeover valve within a control box 24 is changed over by manipulating a remote control key 22, and air is fed to an ejection operating air valve 19 and a walnut supply valve 16. A high-pressure air flows to a branch tube 18a to operate an ejector 8, and the walnut supply valve 16 is opened. Then, husks 3 of walnut accommodated in a tank 4 are absorbed into the ejector 8, and ejected through the tip end of a nozzle 17. The ejected husks 3 are blown to the heat transfer surface and the wall surface to remove adhered scales. Since the husks 3 of walnut have a small repulsion coefficient, the repulsive force at the time of spraying the husks onto heat transfer surface etc. is small. Accordingly, the husks can satisfactorily make contact with the heat transfer surface and the like and adhered scales can be removed.

Title: Thermal head
Inventor: MORIGUCHI HARUHIKO
IPC: H04N1/032
Filed: 1984-09-12
Abstract: PURPOSE:To enable printing with high resolving power even if high speed printing is performed, by making the heat generated in a certain heat generating element hard to conduct to the adjacent other heat generating element. CONSTITUTION:The size R of each of heat generating elements 31 in a main scanning direction is reduced to the half or less of the arrangement pitch of the heat generating elements 31, that is, the center-to-center distance P between both electrodes 12, 13. When the heat generating density of this thermal head is 300 SPI, the distance P is about 84.7mum and the size Q in a sub-scanning direction is about 130mum. The width D between both electrodes 12, 13 is about 45mum and, therefore, the size R in the main scanning direction is about 39.7mum. Because of this, the interval between mutually adjacent heat generating elements 31 is same to the width D between both electrodes 12, 13 and about 45mum being a relatively large size and, as a result, the heat generated in a certain heat generating element 31 is hardly conducted to the adjacent other heat generating element 31 especially through a heat generating resistor 11. Therefore, for example, even if black image information is printed every one dot, the element 31 corresponding to white image information is not heated to a degree performing printing operation.

Abstract: PURPOSE:To enable prevention of coiling of copying paper and to prevent damage on the surface of thermal fixing roll by providing a layer of heat resisting elastic body having wavy sectional form on the surface of a cylindrical mandrel of a thermal fixing roll. CONSTITUTION:The thermal fixing roll 4 consists of a cylindrical mandrel 6 and a layer 7 of heat resisting elastic body having wavy sectional form made of, for instance, silicone rubber of about 30HS hardness and covering the surface of the mandrel 6. A pressure roll 5, similarly with the fixing roll 4, consists of a cylindrical mandrel 9 and a layer 10 of heat resisting elastic body that covers the surface of the mandrel 9. When the thermal fixing roll 4 comes into contact with the surface of the pressure roll 5, crest parts of the wavy heat resisting elastic layer 7 are squeezed by nip pressure, and the roll 4 and roll 5 are brought into uniform contact. When contact of rolls 4, 5 is released, crest parts of the wavy heat resisting elastic layer 7 restore original wavy form. Consequently, the tip of fixed copying paper 11 is pushed out in the direction to part from the roll 4. At the same time, a space is formed between the roll 4 and copying paper 11, and the copying paper 11 is stripped off successively from the roll 4. Damage of the roll 4 due to a stripping claw does not occur.

Abstract: PURPOSE:To make it possible to drive a mechanism with high accuracy through short time processing over wide temperature conditions by subjecting the waveform of output driving pulse from a driving circuit to modification control based on stored driving data for step motor in a motor control circuit. CONSTITUTION:Upon receiving a signal from an actuated control circuit 14, a range finder 15 measures the distance between a camera and an object. At the same time, a temperature detecting circuit 16 detects the ambient temperature of camera. Thus detected temperature T is then compared with a high reference temperature T1. If it is lower than T1, it is further compared with a low reference temperature T2. If it is lower than T1 and higher than T2, a control circuit 14 determines the number of driving pulses required for feeding and focusing a lens 11 based on the measured distance data. At the same time, a driving pulse having optimal waveform for that temperature is selected from a memory circuit 17.
