Patent JP-S5610051-A (JP)
Title: Manufacture of armature
Inventor: HAMANO ISAO
IPC: H02K13/04
Filed: 1979-07-04
Abstract: PURPOSE:To prevent the exfoliation of the insulating film of an armature coil due to the sliding contact caused by the vibration at the time of ultrasonic welding, by providing an interphase space between the lead portion of the armature coil and the end portion thereof and forming the coil. CONSTITUTION:A coil 3 is formed so as to provide an interphase space 14 by arranging a separating member and the like between a lead portion 3a of an armature coil 3 and a coil end portion 3b. Under this state, the lead portion is arranged at the specified position on a segment 7 of a commutator 4, thereafter both portions are electrically and mechanically connected by using a ultrasonic welding device 8. In this case, the sliding contact caused by the relative vibration with respect to the coil-end portion due to the ultrasonic vibration of the coil lead at the time of welding is avoided by the presence of the interphase space. Therefore, the exfoliation of the insulating film of the armature coil can be prevented.

Title: Coated layer removing method
Inventor: ABE NAOTO
IPC: G03G5/08
Filed: 1980-06-25
Abstract: PURPOSE:To remove a coated layer without impairing a substrate, by causing cracks in an impenetrable substance layer coated on the surface of the substrate, introducing into the cracks a substance for expanding on volume expanding treatment, and excecuting this treatment. CONSTITUTION:Cracks are caused by heating, cooling, or the like method in an impenetrable coat layer formed on the surface of a substrate, for example, in the case of removing a photoconductive layer made of Se, an alloy of Se, or the like formed on a conductive substrate for the purpose of its renewal. Sufficient cracks can be produced by rapidly heating the coated layer to a temperature not affecting the substrate unfavorably, and then, rapidly cooling it. The coated layer is removed for example, by introducing water into the cracks and cooling it below the freezing point, or dipping it into a liquid having a boiling point higher than that of water and heated above that of water, or the like method, thus permitting the coated layer to be removed safely without damaging the substrate by applying expansion alternatively by introducing a solution of a compound producing a gas on chemical reaction and heating it to produce the gas (e.g. NaHCO3, NH4NO2, etc. are useable).

Abstract: PURPOSE:To reduce the generation of a torque shock despite of an engine load by a method wherein with the decrease in an engine load during the starting of coupling of a supercharger and release of the supercharger from coupling, an engine output correction amount responding to a change in a supercharger load is increased. CONSTITUTION:A control means 20 inputs signals from an intake air amount sensor 4, an engine rotation sensor 25, a throttle sensor 26, and a water temperature sensor 27.

During the starting of coupling of the supercharger 6 and release of the supercharger from coupling, correction of an engine output is executed in linkage with the motion of the supercharger. The correction amount is controlled based on control characteristics set so that with the decrease in an engine load during shifting of the electromagnetic clutch 14, the correction amount is increased. This constitution reduces the generation of a torque shock.

Title: Controller for motor
Inventor: IIJIMA ATSUSHI
IPC: H02P27/06
Filed: 1984-04-28
Abstract: PURPOSE:To prevent a motor from damaging and to safely and reliably operate the motor by confirming the control of a DC voltage of an inverter of power source side and suitably stopping the operation of a load side at the abnormal time. CONSTITUTION:When the voltage of a DC bus 6 is larger than the set value, a comparator 18 outputs a signal 18a of ''1''. Therefore, when the close command of an AC electromagnetic contactor 3 and the voltage control command value of an AC side inverter 2 are input and the voltage of a DC bus 6 increases larger than the set value, a logic calculator 20 outputs a control allowance signal 20a to an inverter 5, which becomes controllable state. Thus, if the DC voltage is not established, a load side operation can be suitably stopped.
