IPC: G01R33/06
Filed: 1987-10-09
Abstract: PURPOSE:To improve the detecting sensitivity of a sensor, by constituting a full bridge with four barber-pole elements. CONSTITUTION:Conductor layers 2 are formed on an insulating substrate 1. Each layer 2 is formed so that a strip pattern is oriented toward 135 deg. with 0 deg. as a reference. A plurality of layers 2 are aligned in the direction of 0 deg.. The layers are divided into groups 2a-2d. The thin film of ferromagnetic magnetoresistance element is evaporated thereon. The layers 2 in each group are connected in correspondence with the groups 2a-2d. Both ends are connected to wiring layers 3. Resistance layers 4, which are extending in the direction of 0 deg., are formed. At this time, barber pole elements are formed with the layers 2 and 4. The barber pole elements 100a-100d are electrically connected with the wiring layers 3. Thus a full bridge is formed. When a current is made to flow from an electrode 3a to an electrode 3b, a potential difference is yielded between electrodes 3c and 3d in correspondence with a magnetic field.

Title: Variable phase shifting circuit
Inventor: KAWAGUCHI TOSHIHARU
IPC: H03H11/20
Filed: 1985-11-14
Abstract: PURPOSE:To stabilize an output by providing the 2nd differential amplifier, a circuit which synthesizes the 1st-4th signals and obtains a phase variable output signal and a control means which controls together all current sources of the 1st-4th differential amplifiers in common in the same manner and changes the phase of a phase variable output signal. CONSTITUTION:In a variable phase shifting circuit adding vectors through the use of four-phase input signals with phase differences of 90 deg., a common phase shifting control signal controls the current sources S1-S4 of the differential amplifiers D1-D4 so that all four-phase input signals can be amplitude- controlled by the control signal. With Vc (control voltage) = Vr (reference voltage) given, all currents of a current source 22 are set so that they can flow in a transistor Q21. The current division ratio of the current of a current source 21 is changed by varying the control voltage Vc, which means that the variable current sources S1-S4 are simultaneously controlled. Thus a variable phase shifting circuit can be obtained which easily sets the variable range for shifting a phase to 180 deg. and can obtained a stable output without a critical change in the amplitude of said output corresponding to the control.

Title: Drive slip control system
Inventor: TANAKA RYUICHI
IPC: B60T8/58
Filed: 1993-10-13
Abstract: PURPOSE:To make drive slip control quicker by making a discriminating circuit detect a drive slip, and pressurizing working liquid when a pump sucks it, and removing a hindrance resulting from the resistance of a master cylinder in a flow of the working liquid. CONSTITUTION:When a large drive slip occurs in a driving wheel, a discriminating circuit 70 detects the above slip, and simultaneously changes over a cut-off poppet valve 63 to a valve opening position 63b and a pressure regulating valve 60 to a relief position 60b, and actuates a driving motor 28 to drive a pump 55. In addition, the discriminating circuit 70 carrys out control so as to supply a large initial current to a pressurizing device 36 for driving a motor 116 and then to supply a small current. Thus in the case where the pump 55 sucks a working liquid on the side of a master cylinder 3, it consequently sucks the working liquid pressurized by the function of the pressurizing device 36. Namely, since the large initial current is supplied to the pressurizing device 36 at the same time as the pump 55 begins to function, the working liquid is quickly pressurized to make drive slip control quicker.
