    摘要: A motor drive circuit in which a first bipolar transistor is disposed between a ground terminal and one terminal of a motor, and a second bipolar transistor is disposed between the ground terminal and another terminal of the motor. Each of the transistors has a reverse breakdown voltage between an emitter and a collector which is greater than a voltage of a power source and has a reverse-direction h.sub.fe which is greater than or equal to a predetermined value. A resistor and a capacitor are disposed in parallel between respective bases of the first and second bipolar transistors and a ground terminal. Potential drawbacks can be prevented even when voltage of reverse polarity is supplied.

    摘要: An accelerometer sensor is disclosed, utilizing a casing having a center axis, and a pressure sensitive element located at the bottom portion of the casing. A gel based medium is accommodated in the casing. Given that "x" denotes a positional deviation of the pressure sensitive element with respect to the center axis of the casing and that "h" denotes a height of the medium in the casing, the positional deviation (x) and the height (h) are set such that the value 2 x/h falls within a predetermined range and serves as a function of the anisotropic sensitivity ratio of the sensor.

    摘要: A buckle device in which it can be detected whether or not a tongue plate inserted into a case is locked, and in which reliability of such detection is high. In the buckle device, a magnetic plate is provided at a leg portion which moves together with the tongue plate which is inserted into an interior of the case. Changes in orientation of a magnetic field of a magnet of a sensing section, which orientation varies due to the magnetic plate approaching and moving away from the magnet, are detected at an MRE sensor.

    摘要: A magnetic sensor that is inexpensive and suppresses changes in offset voltage caused by wear. The magnetic sensor includes magnetoresistance elements having electrical resistances that change in accordance with magnetism changes. The magnetic sensor detects magnetism based on changes in the electrical resistances. The magnetoresistance elements are covered by a protective film. Part of the protective film is etched and eliminated to form a recess.

    摘要: A rotation detector includes a rotor having a shaft. Projections are located at predetermined intervals on the periphery of the rotor and extend in an axial direction. Magnets are located between the projections and the shaft. The flux of each magnet is detected by a corresponding magnetism detection element. Each magnetism detection element has magnetic resistors. Movement of the projections changes the direction of flux of the magnets. Each resistor is switched between a first state, in which its magnetic resistance is great, and a second state, in which its magnetic resistance is small, in accordance with the change of the flux direction. The resistors are divided into two groups. The groups are substantially symmetrical relative to a centerline of the groups such that, when the direction of the flux changes, the resistors in one group are in the opposite state from the resistors in the other group. The centerline of changes in the direction of the flux matches the centerline of the resistor groups.
