Title: Drive for brushless motor
Inventor: NAITOU NORIYOSHI
IPC: H02P6/18
Filed: 1989-09-01
Abstract: PURPOSE:To detect motor currents without the loss of voltage, and to limit currents by limiting motor currents flowing through a driving transistor when overcurrents are made to flow through a motor and a voltage signal exceeds the level of reference voltage. CONSTITUTION:A motor driving-coil voltage-drop detecting means 6 detects the voltage drops of motor driving-coils 1a, 1b, 1c by motor currents Im from the conduction signals Eu, Ev, Ew of each phase of a motor. A motor current- voltage conversion means 5 detects currents corresponding to motor currents Im as a voltage signal. The output terminal of a current limiting comparator 92 is connected to the common base of current limiting transistors 8a, 8b, 8c. When the load of the motor is increased and motor currents Lm are increased gradually, the output voltage Vout of the current limiting comparator 92 is at HIGH. The transistors 8a, 8b, 8c are turned ON at that time, the base currents of driving transistors 2a, 2b, 2c are made flow, and the title drive is operated so that motor currents Im are not made larger than a current limiting set value.

Patent JP-H04107327-A (JP)
Title: Torque limiter
Inventor: SHIMIZU KYOICHI
IPC: F16D43/21
Filed: 1990-08-29
Abstract: PURPOSE:To arbitrarily change set torque so as to supply stable torque at a low cost by providing a driven side connector which is surface-bonded via screw connection to a drive side connector so as to form a seat surface capable of setting specific torque. CONSTITUTION:A screw threaded in a connector 1 on a drive side and a connector 2 on a driven side is assumed to be a right-handed screw. The connector 1 on the drive side is screwed in, to be pressed against a seat surface A of the connector 2 on the driven side with specific set torque value, followed by being fastened. When rotating torque is transmitted from a drive shaft 3 to a driven shaft 4, the torque is transmitted by leftward rotation because the screw connection between the connector 1 on the drive side and the connector 2 on the driven side is threaded rightward. If the transmission torque is lower than the set torque value, the rotating torque can be transmitted from the drive shaft 3 to the driven shaft 4 by frictional force of the seat surface A. When torque larger than the set torque value is generated, an end surface of a male screw 1b of the connector 1 on the drive side is slidden on the seat surface A of the connector 2 on the driven side so that screw connection between the connector 1 on the drive side and the connector 2 on the driven side is loosened, thus preventing the transmission of the torque.

Abstract: PROBLEM TO BE SOLVED: To stabilize beam emission while restricting the generation of creeping discharge in an insulator by setting the natural resistance of the insulator for insulating plural electrodes for accelerating charged particles emitted from an emitter within a specified range. SOLUTION: An insulator 105 for insulating an electrode 102 for leading electron from an emitter 101 and an electron accelerating positive electrode 103 from each other is made of semiconductive material, and the natural resistance ρΩ is set from SV2/aL to SV/10 LI, where L is the length of the insulator 105 between the electrodes in the insulating directon, S is the cross sectional area of a vertical surface between the electrodes, V is an electrical potential difference between the electrodes, I is a current by the charged particle, and (a) is the upper limit of heating amount of the insulator.  Even in the case where the secondary electron 112 is emitted from the insulator 105 so as to form the positive charge 113, the electron is moved in the insulator 105 from the electrode 102 toward the positive electrode 103 so as to offset the electric field formed by the positive electric charge 113, and the electric field formed over the connection point 122 is maintained small so as to prevent the generation of the creeping discharge and to restrict the heat generation of the insulator to the allowable value or less.

Title: Device for discriminating failure
Inventor: TSUKAHARA KATSUMI
IPC: G06F11/00
Filed: 1990-08-30
Abstract: PURPOSE:To discriminate a storage element frequently generating ECC errors by providing this failure discriminating device with a means for storing the statistic frequency of ECC error detections, counting up the frequency and storing the counted value. CONSTITUTION:In an initial state, an initial value is set up in an error buffer 80 and a count register 60. A microinstruction(MI) stored in address '3' of a control storage 10 is read out and stored in a reading register 30. When an ECC checking circuit 50 detects an ECC error in the MI stored in the address '3', an adder 70 forms the statistic frequency value '1' of the ECC error detection and stores the value '1' in the address '3' of the buffer 80. The value '1' is applied and stored to/in the register 60. In this case, the address to be applied to the control storage 10 is the same as that to be applied to the buffer 80. Consequently, a failure position in the storage element is easily discriminated.

Title: Dry transformer
Inventor: FUKUDA NOBUO
IPC: H01F27/32
Filed: 1983-12-06
Abstract: PURPOSE:To obtain the titled device having a high creeping withstand voltage by reducing the creeping dimension by a method wherein the electric field of the part of adhesion of an insulator having a higher specific dielectric constant than air is relaxed by enveloping the peripheral surface of coil end on the high voltage side with an insulator having a high dielectric constant. CONSTITUTION:Windings of electric wires 9 coated 10 by insulation are laminated without spacers and then impregnated with H-type varnish. Rubbery substance is buried between an insulation barrier 21 and the coats 10, between winding end surfaces and an insulation washer 24, and between the barrier 21 and a high voltage collar 23, and an outer insulation layer 25 is produced by winding with an insulation tape, including the collar 23. This high voltage coil is supported at four points per coil phase with an insulator 22 in common to a low voltage coil 13, and the barrier 21 is coated in contact with the inner peripheral surface of the color 23. With this construction, even when the penetration of impulses causes ionization in the air gaps between the high and low voltage coils, the insulator such as the barrier adhered to the inner and outer peripheries of the high voltage coil blocks insulation breakdown, and the insulators at the upper and lower ends of the high voltage coil relax the voltage at the coil end, thus enabling a large reduction in the coil creeping length la; accordingly, coil supporting can be simplified, resulting in the improvement of the reliability.

Title: Heat sensing flow rate sensor
Inventor: YAMAKAWA TOMOYA
IPC: G01F1/692
Filed: 1992-08-28
Abstract: PURPOSE:To obtain a low cost heat sensing flow rate sensor with good response capability by providing a part of heating part of a flow velocity probe with a fluid space which is not diretly exposed to the fluid varying its velocity. CONSTITUTION:A heat sensing flow rate sensor is provided to a part of heating part of a flow velocity probe 3 with a fluid space which is not diretly exposed to the fluid varying its velocity. The heating part not diretly exposed to the fluid varying its velocity has no forced convection loss and quite a little heat is taken by the fluid compared with the part exposed to the fluid varying its velocity. Thus, the heating part not diretly exposed to the fluid varying its velocity is kept at higher temperature than that without a wind shield 12. Even when the fluid flow rate varies, the variation of heat flow from a support base material 5 plated with heat sensing resister 6 to a holder 10 is small. Therefore, the heat time constant for heat balance state in the probe 3 and the holder 10 is shortened. By this, in the case of sudden change in fluid flow, the time for reaching the balance state of temperature corresponding to the velocity is short enough and the response capability as a flow rate sensor becomes good.
