Title: Recording and reproducing device
Inventor: TAKAHASHI TOSHIHIKO
IPC: G11B15/467
Filed: 1985-05-30
Abstract: PURPOSE:To shorten the period when no contact is secured between a rotary head and a magnetic tape and to increase the quantity of information read out during a unit time, by accelerating and decelerating the drum revolution for the period when the rotary head has no contact with the magnetic tape in a high-speed search mode. CONSTITUTION:In a high-speed mode the maximum voltage is applied to a motor 9 for a period between t1 and t2 when the rotary heads 10 (10A, 10B) have no contact with a magnetic tape 11. Thus the motor 9 is accelerated. While the motor 9 is decelerated with the minimum voltage applied to the motor 9 for a period between t2 and t3. The drum revolving angle is set at 90 deg. for a period between t1 and t3 after the pulses supplied from a frequency generator set at the drum of the revolving side. While the angular revolutional frequency is kept at omega1(t1)=omega2(t3)=omega0 by a drum servo circuit. In such a way, the time t1 needed for 90 deg. revolutions of a fixed speed is reduced down to t3-t1=tx. As a result, the section T1 where the head 10 has a contact with the tape 11 is increased in a rewind mode with a no-contact section T2 reduced respectively. In such a way, the quantity of the read-out information per unit time is increased.

Title: Transformer
Inventor: YOSHIDA TETSUO
IPC: H01F30/00
Filed: 1979-09-14
Abstract: PURPOSE:To obtain the compact AC-DC combined transformer with a high efficiency by initially switching the polarity at a frequency higher than that of the input voltage so as to effect the secondary conversion with the high frequency transformer and the returning it to the original position at such a higher frequency. CONSTITUTION:AC (or DC) voltage from input terminals 21 and 22 is fed to the first polarity switching means (for example, MOS-FET251-258) and is excited with an output of a square wave osillator 30 which outputs a frequency higher than that of the input voltage and after switched in the polarity, it is fed to a high frequency transformer 27 to effect the secondary conversion at the turn ratio of n2/n1. The output is fed to the second polarity switching means (for example, MOS- FET261-268), rectified synchronizing with the high frequency of an oscillator 30 and outputted to output terminals 23 and 24 after transformed. Such higher frequency by the switching technique can reduce the amount of iron and copper to be used for transformers thereby assuring a compact and light transformer with a high efficiency.

Filed: 1990-05-09
Abstract: PURPOSE:To reduce the quantity of scavenging air blowing through a cylinder by providing an air in-take hole, which communicates a scavenging chamber in the top section of a liner and an opening and closing valve on the outer periphery of the scavenging hole. CONSTITUTION:In a 2 cycle uni-flow type internal combustion engine, an air in-take hole 51 communicating to a scavenging chamber 10 is provided to the portion upper than the scavenging hole 14 of a liner 20. In addition, an opening and closing control valve 52 is provided on the outer periphery of the air in-take hole 51.

Filed: 1988-05-12
Abstract: PURPOSE:To decrease contact heat resistance at the time when it is attached to a cooling plate by providing a metallic plate which has thermal expansion coefficient almost the same as that of an insulating substrate on the other face of a heat radiation plate. CONSTITUTION:A metallic plate 7 having thermal expansion coefficient almost the same as that of an insulating substrate 3, for example, 42 alloy (Fe 58%, Ni 42%) is attached to the reverse of a heat radiation plate 1. In the case that the insulating substrate 3 is alumina ceramics, that thermal expansion coefficiency is 6.7X10<-6>1/ deg.C and that of 42 alloy is 4.2X10<-6>1/ deg.C, therefore when it is cooled after the insulating substrate 3 is soldered to the heat radiation plate 1, the heat radiation plate 1 slightly bends convexly toward the metallic plate 7 side, but by fastening and fixing both sides of the heat radiation plate 1 with screws, the bending of the heat radiation plate 1 is rectified such that it becomes parallel with the surface of the cooling plate. Accordingly, contact heat resistance resulting from space generated between the cooling plate and the heat radiation plate can be neglected.

Abstract: PURPOSE:To perform accurate positioning and facilitate teaching operation, by reducing manual operating force. CONSTITUTION:To cause a robot to perform teaching, a jig is removed and a four-way shift valve 12 and a teaching lever 13 are attached together to a jig holding plate 11.

Title: Muting circuit operated by voltage fluctuation
Inventor: INOUE SHIYOUJI
IPC: H03G3/34
Filed: 1982-07-09
Abstract: PURPOSE:To attain the muting of a low frequency circuit with the power supply turned off or prevent the malfunction of a logic circuit in high speed, by bringing the muting circuit to a ground potential with the operation of a transistor (TR), when a fluctuation of the power supply voltage is detected. CONSTITUTION:If the power supply voltage of the titled circuit fluctuates or the on/off of a power supply switch is repeated, a diode 4 senses the voltage fluctuation. The potential of a diode 5, in this case, is made constant because the voltage before fluctuation is charged in a capacitor 6. Thus, when the base potential of a TR2 is lower than the emitter potential, the TR2 turns on, a discharge current flows from the capacitor 6, then a TR3 turns on, the circuit connected to the collector of the TR3 is grounded for applying the muting.
