Title: Thermal resistance device
Inventor: MURASE YUICHI
IPC: F28F13/00
Filed: 1989-05-18
Abstract: PURPOSE:To simplify a heat resistance device by constituting the heat resistance device, which is used for performing a heat exchange between two objects provided to be detached from each other, so as to change thermal resistance by changing the volume occupied by a heat transfer material in a cylindrical member. CONSTITUTION:This heat resistance device 3, which is used for performing a heat exchange between objects 1, 2 provided separately from each other, is provided with an almost cylindrical member 4 formed by a material of low thermal conductivity and a means for changing the thermal conductivity. Each object 1, 2 is respectively connected in the vicinity of both ends of the cylindrical member 4, and the means for changing the thermal conductivity is constituted such that the volume, occupied by a heat transfer member 5 consisting of material of high thermal conductivity in the inside of the cylindrical member 4, can be freely changed in its axial direction. By the constitution such that heat resistance is changed by changing the volume occupied by the heat transfer material in the cylindrical member 4, the heat resistance device can be simplified.

Title: System for controlling hysteresis motor
Inventor: SASAKI KOUJI
IPC: H02P27/06
Filed: 1977-10-15
Abstract: PURPOSE: To permit a hysteresis motor to sufficiently respond to the load variations by controlling the power so that the frequency of the power becomes in difference from the revolving frequency preset value to thereby minimize the accelerating time of the motor.  
     CONSTITUTION: When a hysteresis motor is accelerated to become fIN<fM+fO, it becomes Vs=O. Then, a servo motor 11 moves in positive direction to thereby cause VIN to increase and fIN to become high. When the fIN increases and it becomes fIN>fM+fO, it becomes fM<O to thereby decelerate the speed of the servo motor 11 so as to decelerate it. Thus, the motor is accelerated while controlling the output frequency by a power frequency controller 8 to become fIN=fM+fO. The timing variations of fM becomes dfIN/dt=dfM/dt, because (GD 2 /4)dfM/dt=TM-TL where the system inertia moment is represented by GD 2 , motor torque by TM and load torque by TL, and th relationship fIN=fM+fO becomes consistent in acceleration in a manner to rapidly accelerate with light load and to slowly accelerate with heavy load

Filed: 1989-05-18
Abstract: PURPOSE:To automatically detect the breakage of dot pin by mounting a means successively selecting the respective dot pins of a printing head and a means printing a test printing pattern on printing paper. CONSTITUTION:A printing control part 11 receives printing data from a test printing pattern memory 24 to continuously output the first pin by a width (n) mm and subsequently feeds printing paper 14 by one dot diameter on the basis of the signal from a paper feed control circuit to continuously output the same by the width (n) mm. In the same way, when output is performed in the order of a3-a5, a black test printing pattern (a) having a length (n) mm and a width 1mm is outputted and the second and third pins are continuously printed by the width (n) mm to output test printing patterns (b), (c) but, when the third pin 3 is broken, the test printing pattern (c) becomes low in density. The printing paper 14 is successively fed during a time when the dot pins of a printing head 1 are continuously struck until the last pin and the test printing patterns are successively read by a reflection sensor 12 and a detection circuit part 13 judges that the test printing patterns (a), (b) are normal and the test printing pattern (c) is abnormal. Therefore, the breakage of the dot pin can be detected automatically.

Filed: 1995-04-25
Abstract: PURPOSE: To switch a fluid pressure drive unit by sensing the reduction of discharged fluid pressure at the end of movement of the fluid pressure drive unit in either direction of the reciprocation. CONSTITUTION: This invention relates to a method of reciprocating a piston 12 automatically in a cylinder 10 of a piston-cylinder unit, in which the piston 12 reciprocates alternately to the opposite sides of the cylinder 10 between the limits with a distance from each other with fluid pressure applied from a fluid pressure source 46, and at the same time, fluid pressure is let out from the side of the cylinder 10 in the moving direction of the piston 12. When the piston 12 reaches the limit of moving in one direction in the cylinder 10, the reduction of the discharged fluid pressure in the cylinder 10 is utilized for applying the fluid pressure to the side of the piston 12 which reverses the moving direction of the piston in the cylinder 10.

Then, a fast forwarding means 3 relatively moves the wheel spindle stock with respect to the work piece W by fast forwarding, and it is moved to the prescribed position based on the diameter dimension measured by the initial diameter measuring means 2. A discrimination means 4 discriminates from which grinding work is to be started among coarse grinding, precise grinding and micro grinding based on the diameter dimension measured by the initial diameter measuring means 2. A grinding feed means 5 drives the wheel spindle stock 13 based on the discrimination result of the discrimination means 4 and the repairing work of the work piece W is executed.  Thus, the repairing of the work piece W can easily be executed.

Filed: 1984-06-15
Abstract: PURPOSE:To ensure the operation of a switching Tr controlling the short-circuit/ opening of a capacitor by providing a delay characteristic to a delay drive source comprising a diode and a resistor. CONSTITUTION:Diodes 14, 15, 16 and resistors 17, 18, 19 constitute the delay drive source. Since the rising of an anode potential of the diode 24 is slow in comparison with that of the diode 15, when the potential of a power supply 20 starts rising, a transistor (Tr)12 is turned on by the anode potential of the diode 15, a mirror circuit 10 is actuated to turn on a Tr5 thereby discharging the electric charge of the capacitor 4. Thus, the anode potential of the diode 14 rises, a Tr13 is turned on, a mirror circuit 11 is actuated and then a Tr6 is turned on. As a result, the Tr5 is turned off, the capacitor 4 starts charging and an output of the inverter 2 goes to ''L'' when the potential reaches a prescribed potential.

Abstract: PURPOSE:To obtain a cylinder device which moves the position in the cylinder to an arbitrary position to make reciprocating motions by changing the residual magnetic field distribution of a cylindrical superconducting body having a strong pinning force by utilizing a non-contact floating phenomenon caused by the residual magnetic field of the superconducting body. CONSTITUTION:When electromagnets 3 and 4 are respectively provided at each end of a cylindrical superconducting body 1 and one electric magnet 3 is energized, the body 1 forms the peak of a residual magnetic field at the position of the electromagnet 3. A piston 2, the stroke length of which is decided by means of the distance between the electromagnets 3 and 4 and which is made of a permanent magnet or in which a permanent magnet is incorporated, moves to the peak position of the residual magnetic field. When an electric current which offsets the residual magnetic field is made to flow to the electromagnet 3 and, at the same time, the other electromagnet 4 is energized, the peak of the residual magnetic field is formed at the position of the electromagnet 4 and the piston 2 moves to the peak position. Therefore, a cylinder device which changes the stroke length of its piston and makes the piston perform smooth reciprocating motions by adjusting the values of the currents made to flow to the electromagnets and forming the peak of the magnetic field at arbitrary positions in such way can be obtained.
