Title: Induction motor controller
Inventor: WATANABE HIDENORI
IPC: H02P27/06
Filed: 1987-05-20
Abstract: PURPOSE:To prevent generation of higher harmonics from an induction motor and contrive to lower noise by providing a power-factor control means so as to make the power factor of a converter input current variable to vary a DC output voltage of said converter. CONSTITUTION:A speed command value for an induction motor 8 is sent from a speed commander 38. The relation between said speed command value and a dead time is such that the dead time is long when the speed command value is sent at a low speed while said time shortens as the speed of said command value becomes higher. Therefore, if a zero point detected in a zero-phase detector 30 by a dead-time generator 37 is delayed by a dead time, the phase of a current command can be delayed by said dead time as compared with the phase of a supply voltage. Accordingly, it is possible to vary the output voltage of a converter 26 and to conduct a pulse amplitude modulation control.

Title: Electric blower
Inventor: KATO KENJI
IPC: H02K13/00
Filed: 1994-06-02
Abstract: PURPOSE:To achieve a smooth rectification operation without generating a step in an armature even in the case of high output, high input, and high-speed rotation by forming an insulating material for holding the armature from high- strength, highly heat-resistant fine ceramic. CONSTITUTION:In a commutator 22, a plurality of commutator pieces 23 are held by insulation and adhesion with a fine ceramic material consisting of such materials as alumina, zirconia, and silicon nitride being included among the commutator pieces. When conditions scatter due to temperature increase caused by thermal stress in the case of the fusing connection of a coil to the commutator pieces 23 and sparks during operation, centrifugal force, etc., a step tends to be generated easily among the commutator pieces 23. However since an insulating material for retaining the commutator piece 23 is made of high-strength, highly-heat-resistant fine ceramic material 24, the generation of step can be prevented, thus continuing a smooth commutation operation.

Title: Limit switch
Inventor: HORIKOSHI KAZUHIKO
IPC: H01H35/00
Filed: 1995-05-19
Abstract: PURPOSE: To prevent the occurrence of continuity trouble of a contact by making a limit switch contactless and besides, to enable the inspection of the limit switch for soundness. CONSTITUTION: For a limit switch 2, the light emitting diode 4D of the photosensor 4 emits light by the power source supplied from external terminals P and N. A shielding plate goes out and comes in, according to the action of an object, between the light emitting diode and a light receiving diode 4T. A main transistor T1 is turned on or turned off, according to the state of this shielding plate, and the on and off of the limit switch is changed over. By this circuit, a contactless limit switch can be obtained. Since the power source for controlling the main transistor and the power source of a circuit wherein the limit switch is used are used in common, the necessity for insulation between powers is dispensed with. Furthermore, the replacement with a conventional limit switch with a contact can be performed simply.

Title: Image forming device
Inventor: TANAKA HITOSHI
IPC: G03G21/00
Filed: 1984-06-13
Abstract: PURPOSE:To prevent the formation of a defective image due to dew condensation through simple constitution by providing a means which detects part of liminous flux passed through an optical system by a photodetecting element and decides whether dew condensation occurs in the optical system or not on the basis of the detection output. CONSTITUTION:A standard white plate 10 is irradiated by a lamp 2 and a photosensor 12 photodetects part of the luminous flux passed through the optical system consisting of reflecting mirrors 4-6, a lens 7, and a reflecting mirror 8. The output of this sensor 12 is compared with a reference signal by a comparing circuit 15, which generates an H output when the sensor output exceeds a specific level, so that an LED16 does not illuminate. If even one of optical systems is in a dew condensation state, on the other hand, the quantity of light detected by the sensor 12 drops below the specific value and the circuit 15 outputs an L-level signal, so that the LED16 illuminates. Consequently, the dew condensation of the mirrors 4-6, and 8 or lens 7 of the optical system is displayed and a signal is sent to a CPU, thereby inhibiting copying operation so that the copying operation does not start even when a copy key is turned on.
