Title: Controller for lockup clutch
Inventor: SUZUKI YUTAKA
IPC: F16H61/14
Filed: 1990-04-06
Abstract: PURPOSE:To prevent any delay of clamping for a lockup clutch or shock from occurring by compensating an operating signal to an electrical actuator so as to make the lockup clamping time accord with the desired value. CONSTITUTION:When the time till a lockup clutch is completely clamped since a clamping command means has started the output of an operating signal to command an electrical actuator for its clamp, is longer than the desired clamping time, compensation for the operating signal takes place so as to increase the clamping time. When actual clamping time is shorter than the desired clamping time the other way, compensation for the operating signal is carried out so as to decrease the clamping time. Consequently, the actual clamping time is accorded with the desired clamping time and thus it is stabilized. In this connection, the desired clamping time should be varied according to engine load.

Title: Magnetic field sensor
Inventor: YAMASHITA ICHIROU
IPC: G01R33/032
Filed: 1980-07-07
Abstract: PURPOSE:To detect direct current magnetic field components and further makes a sensor stable against temperature by making a magnetic thin film, a polarizing film and light detection mechanism in one unit and detecting a magnetic field by utilizing the holding force of the magnetic thin film and Faraday effect. CONSTITUTION:The whole magnetization of a magnetic thin film 2 is orientated in the negative direction of the Y axis by a magnetic field generating coil for initialization. At this time, if the magnetic field is applied to Y axis, magnetization is reversed in a part 9 where the coercive force Hc is less than the external magnetic field, and no reversing takes place in a part 10 where it is greater. Owing to the  fact, as the polarizing plane of measuring light 7 that is polarized by a plarizing  plate 1 is subjected to revolution in the reverse direction to each other in the part 9  and the part 10, in a light detecting film 5 combined with the polarizing plate 4 right under the part 9, a large light detecting output is obtained, and right under  the part 10, an attenuated output is obtained. Therefore, if the holding force of the  magnetic thin film has been found out as a function of the position in advance, the  external magnetic field can be detected form the position of a magnetic wall 11.  Thus also record and memory of the local Max. magnetic field are available, and a  magnetic field can be recognized with naked eye.

Title: Inductive load controller
Inventor: CHIERII MISHIERU ARAN SHIKAARU
IPC: H03K17/0412
Filed: 1989-04-14
Abstract: PURPOSE: To prevent an excess voltage from disturbing a circuit operation by preventing or prevention-releasing the continuity of a power transistor by the source of a transistor. CONSTITUTION: Immediately when a voltage between the gate of a transistor 2 and a +Vbat line is beyond a voltage Vz (instant t2), a diode 9 is conducted. In this case, currents are allowed to run through an equivalent resistance Rdson of the drain source circuit of a transistor N1. An inter-gate source voltage Vgson for resuming the continuity of a power transistor 2 is established in the transistor 2 (a part C of a curve). Then, currents are gradually reduced by restoration to this continuity. Thus, this circuit can be protected from a high negative voltage appearing in the middle of the raid discharge of energy stored in an induction load.

Title: Balancing circuit of load current
Inventor: YAMASHITA TAKASHI
IPC: H03K17/12
Filed: 1983-05-30
Abstract: PURPOSE:To eliminate the use of many balancing transformers or a transistor which has a margin of breakdown strength by adding a collector current negative feedback winding to a driving transformer to correct an unbalanced current. CONSTITUTION:For a driving transformer DT, a winding N2 is used for negative feedback and a winding N3 is used to give the positive feedback of the sum of collector currents of all transistors TRQ1-Qn to the base of each TR and then supply a base current after these TRs are turned on. In such constitution of driving circuits A1-An, the current flowing to the winding N3 is positively fed back to a base winding N1. However the collector current of each TR flowing to the winding N2 is negatively fed back to the N1. This current can balance the current in a saturated ON state of plural switching TRs connected in parallel to each other and also can balance the variance of turn-off characteristics. Thus the voltage waveform obtained in a turn-off state of each TR can be balanced even with the inductance load.
