Title: Magneto-resistance effect type playback head
Inventor: KANE JIYUNICHI
IPC: G11B5/39
Filed: 1990-03-08
Abstract: PURPOSE:To control the magnetic domain of an MR element and to allow the control of Barkhausen noises by providing the closed magnetic path patterns of ferromagnetic thin films at both ends of the MR element. CONSTITUTION:A magneto-resistance effect type playback head 11 is formed via an insulator 13 on a substrate 12. Fine pieces 15, 15' of drawing-out conductors for passing sense currents are provided on both sides of the sense region PQRS in the rectangular part in the central part of the MR element (magneto-resistance effect type element) consisting of the ferromagnetic film of the magneto-resistance effect type playback head 11. The doughnut-shaped closed magnetic path patterns 16, 16' respectively consisting of the ferromagnetic films are formed at both ends of the MR element 14. The closed magnetic path patterns 16, 16' annihilate the magnetic domain of the MR element 14 in this way and, therefore, the generation of the Barkhausen noises is suppressed.

IPC: H03K4/06
Filed: 1982-04-01
Abstract: PURPOSE:To obtain a triangular wave with a 50% duty cycle by connecting a charged and discharged capacitor to the connection point of series-connected transistors (TR) and tuning on and off those TRs and TRs constituting a current mirror circuit alternately. CONSTITUTION:At a charging and discharging circuit part 2, Trs T5 and T8 are connected in series and a capacitor C0 is connected between the connection point A and grounding point. Further, series circuit of TRs T4 and T7 is provided in parallel to the TRs T5 and T8 to constitute the current mirror circuit. In power-on operation, the TRs T4, T7, and T8 turn off and the TR T5 turns on under the control of a charge/discharge switching part 4, differential circuit part 3, and biasing and controlling part 2 to flow a charging current I1 from a power source Vcc to the C0 through resistances R0 and RV. In this case, the base of the TR T5 is held at the emitter potential of the TR T3 determined by a control part 1, so the current I1 is constant. When the potential at a point A reaches the voltage division point B of resistances 18 and 19, the TR T5 turns off and the TRs T4 and T8 turn on under the control of the circuit part 3 and switching part 4 and the C0 is discharged to flow a current I3 equal to the current I1. When the potential at the point A drops to a specific value, the TR T8 turns off and the TR T5 turns on again to charge the C0.

IPC: G01P5/00
Filed: 1979-05-04
Abstract: PURPOSE:To reduce the influence of distribution of flow velocity and to simplify the constitution, by using a multi-beam oscillator. CONSTITUTION:A time-difference-to-voltage conversion circuit 38 generates a voltage corresponding to the time of transmission in the same direction as the flow of ultrasonic waves between a wave transmitter 12 and a wave receiver 13. Switches 34, 35 are then shifted to an ultrasonic wave transmitter 17 and an ultrasonic wave receiver 16 to produce a voltage corresponding to the time of transmission in the same direction as the flow of ultrasonic waves between the transmitter 17 and the receiver 16. The switches 34, 35 are thereafter shifted to an ultrasonic wave transmitter 19 and an ultrasonic receiver 18 to produce a voltage corresponding to the time of transmission of ultrasonic waves. The mean value of these voltage is determined. Oscillators 24, 25 take oscillation frequency levels corresponding to the mean value of the time of transmission in the same direction as a fluid of the three groups of the ultrasonic transmitters and receivers or the mean value of the time of transmission of ultrasonic waves in the opposite direction to the flow of the three groups. The difference between the oscillation frequency levels is detected by a frequency difference detection circuit 53, the detection output of which is proportional to the mean velocity of flow in a measured pipe passage.

Title: Carburetor
Inventor: NAKAMURA YOSHIAKI
IPC: F02M7/23
Filed: 1984-03-23
Abstract: PURPOSE:To permit to select the starting time of suction of main fuel properly and make a power valve unnecessary by a method wherein the intake ports of main air bleed of the carburetor are arranged respectively at positions near a large venturi, a little bit upstream and a little bit downstream of a throttle valve totally closed. CONSTITUTION:The main air bleed 11, communicated with a main nozzle 2, is communicated with the port 16p1 near the large venturi 10 through a path 16A in a small venturi assembly, the port 16p3 located a little bit upstream of the throttle valve 14 closed totally through the path 16B and the port 16p2 located a little bit downstream of the same valve 14 closed totally through the same path 16B. The average pressure of the holes 16p2, 16p3 effects on the main air bleed during totally closed condition of the throttle valve and the slightly opened condition of the same valve. Accordingly, the starting time of suction of main fuel upon the initial period of opening of the throttle valve can be set by the positions of respective holes. A pressure in the hole 16p1 becomes negative due to the high vaccum of the venturi 10 near the totally opened condition of the throttle valve and the main air bleed is reduced, therefore, fuel discharging amount is increased thereby unnecessitating the power valve.
