Title: Printed coil unit for small-sized actuator
Inventor: KOYAMA RYOHEI
IPC: H02K29/08
Filed: 1985-05-17
Abstract: PURPOSE:To equalize a magnetic field applied to a magnetic detector by burying all magnetic detectors in one of printed coils which forms a coil unit. CONSTITUTION:A plurality of spiral patterns 3 are formed on both sides of a printed coil support to form a printed coil. All magnetic detectors 8 are buried in one of printed coils which form a coil unit. Thus, since distances from a magnet to the detectors accurately coincide, a magnetic field applied to the detectors becomes constant. The coil buried with the detectors 8 is disposed nearest the magnet in the unit. Thus, since the magnetic field applied to the detectors is strengthened, the switching timing of a current can be accurately set to reduce an irregular torque.

Abstract: PURPOSE:To improve the operating efficiency by providing a function of calculating the center of a hole having a circular arc part from optional three points on the circular arcs. CONSTITUTION:A work 2 is moved so that a wire 5 contacts the circular arc part of a hole 9, and the position of the wire 5 when the wire 5 contacts the circular arc part of the hole 9 is determined to be stored in a arithmetic unit 8.

Filed: 1992-04-24
Abstract: PURPOSE:To miniaturize a drive circuit and speeds up switching by turning on/off push/pull drive of a drive circuit where a part to be driven is subjected to push/pull drive with a relatively large amount of current by an analog switch IC. CONSTITUTION:When an analog switch IC11 is switched to a contact A side, a second operational amplifier (OP) 4 for driving is used as a non-inverted equal-scale type amplifier and an output voltage V2 which is in phase with and has the same amplitude as an output voltage V1 of a first operational amplifier (OP) 2 for driving is output from the output terminal, thus eliminating voltage difference between the output terminals of the OPs 2 and 4 and preventing push-pull drive of a movable part 3. On the other hand, when the IC 11 is switched to the side of a contact B, 0P4 is used as an inverted equal- scale type amplifier and then the output voltage V2 which is out of phase and the same amplitude and the output voltage V1 of the OP 2 are output from the output terminal, thus feeding a drive current corresponding to the potential difference between the output voltages V1 and V2 to the drive coil of the movable part 3.

Filed: 1990-04-19
Abstract: PURPOSE:To allow production with stable card quality by providing plural endless grooves varying in transverse positions on the outer peripheral surfaces of 1st and 2nd heating and pressurizing roller pairs, providing the projections corresponding to these grooves and fitting the projections into the grooves of the roller pairs. CONSTITUTION:The 1st heating and pressurizing roller pair 62, the 2nd heating and pressurizing roller pair 63 disposed at an arbitrary spacing therefrom, and the guide members 61 provided in the inlets and outlets of the heating and pressurizing roller pairs 62, 63 are disposed. The plural grooves 62a, 63a varying in transverse positions are provided on the outer peripheral surfaces of the 1st and 2nd heating and pressurizing roller pairs 62, 63 and the projections 61a of the guide members 62 are fitted into these grooves, by which this device is constituted. The front end of a film 3 is, therefore, deformed by the influence of heat when the front end approaches the heating and pressurizing roller pair 62, but since the projections 61a of the guide members 61 are held fitted into the grooves 62a, the front end of the film 3 passes the spacing between the roller pair 62 while the front end is corrected. The same holds true of the 2nd heating and pressurizing roller pair 63. The product surfaces of the cards are cleanly laminated at all times in this way.

Filed: 1988-04-29
Abstract: PURPOSE:To reduce operating trouble caused by telephone calls by providing plural recording circuits to a telephone number sending circuit to hold the telephone number used for calling and to optionally set the reoutput and securing the application of said telephone number and reoutput after necessary time. CONSTITUTION:Number holding memory circuits M1-Mn are added to a telephone number sending circuit SND. When digit buttons 1-9 are designated after a reoutput button LIT, the telephone number held by the designated one of circuits M1-Mn is sent to a sending number control circuit CONT and displayed on a number display circuit DSY. At the same time, the dial pulse signal is sent to a subscriber telephone circuit from the circuit SND. The circuits M1-Mn can use repetitively the held tape as long as no writing action is carried out. Thus the number of touches is decreased and the handling is facilitated in a retransmission system for telephone numbers.
