Patent JP-S5610052-A (JP)
Title: Commutator of dc motor
Inventor: FUKUOKA TOSHIAKI
IPC: H02K13/14
Filed: 1979-07-05
Abstract: PURPOSE:To effectively suppress the generation of sparking voltages by shifting the times of the contact and opening of two divided brush pieces and commutator bars, and connecting a series circuit of a resistor and a capacitor, to which a diode is connected in parallel, between the divided brush pieces. CONSTITUTION:At the time of commutation, since the outer divided brush pieces 21 and 31 are switched faster than the inner divided brush pieces 22 and 32 with respect to commutator bars 11-13, a surge voltage is generated from the brush pieces 21 and 31 to the brush pieces 22 and 32. With the brush pieces 21 and 22, for example, since the resistor R1 and capacitor C1 are connected between the brush piece 21 and the brush piece 22, the apparent resistivity becomes high and the surge voltage is absorbed by the capacitor C1. When the commutator rotates and the brush pieces 21 and 22 are shorted by the same commutator, the absorbed charge in the capacitor C1 is discharged through the diode D1. With the brush pieces 31 and 32 the same operation is carried out. In this method, the generation of sparking voltages can be effectively suppressed, and the burning of the brushes and the commutators, the generation of electric noises, and the like can be reduced.

Title: Lead frame for semiconductor
Inventor: SOEDA MASUMITSU
IPC: C25D7/12
Filed: 1988-04-07
Abstract: PURPOSE:To enhance a close adhesion property of an oxide film of copper or a copper alloy and to effectively prevent the oxide film from being stripped off by a method wherein a Cu-Ag alloy layer is coated on the surface of a copper or copper alloy-based lead frame and this alloy layer has a specific Ag content and a specific thickness. CONSTITUTION:The surface of a copper or copper alloy-based lead frame is coated with a Cu-Ag alloy layer. It is required that a thickness of the alloy layer is at least 0.1mum or higher. When the thickness is less than 0.1mum, a base metal element is diffused into the Cu-Ag alloy layer during a high-temperature heating process; a close adhesion property of an oxide film with reference to the lead frame is lowered. It is desirable that an Ag content in the alloy layer is 0.005wt.% or higher. A lower limit of the Ag content to obtain a practical effect is 0.005wt.%. By this setup, migration is not caused; it is possible to obtain the excellent close adhesion property of the oxide film of copper or a copper alloy.

Title: Stopping method of tape-like recording medium
Inventor: KOUZUKI SUSUMU
IPC: G11B15/18
Filed: 1984-04-27
Abstract: PURPOSE:To reduce the influence of inertia extremely and to stop a tape-like recording medium at a required stopping position by travelling the recording medium at a low speed in a prescribed direction at a time immediately before the stop of the recording medium. CONSTITUTION:When a head 5 arrives at a point G ( 52), the output of a detecting circuit 201 is turned from H to L, so that the device is turned to a stop mode to stop the travelling of the tape, but the tape is not actually stopped due to inertia until the head 5 reaches a point I. When the device is turned to the stop mode, a signal T'8 is turned to H and a pulse indicating the head of a blank is supplied to one input terminal of an AND gate 222 through a delay circuit 217 for a light period. Since the signal T'8 is in the H state again, a narrow pulse is outputted from the AND gate 222 as a signal T'2, the device is turned to a reverse P/B mode and the tape starts to travel at a low speed in the reverse direction. When the head 5 reaches the point G ( 54) again, the output of the circuit 201 is turned from L to H and thereby the device is turned to the stop mode again, but the tape is stopped at a position (O55) where the head 5 is close to the point G because the travelling speed of the tape is slow.
