Title: Method and device for computing wheel speed
Inventor: SAKUMA MASARU
IPC: G01P3/489
Filed: 1989-11-02
Abstract: PURPOSE:To quickly compute appropriate temporary wheel speed even in deceleration by assuming time difference between sampling time this time and the latest pulse detecting time before that time as an edge interval, and using computed temporary wheel speed. CONSTITUTION:A sensor pulse supplied corresponding to the increment/ decrement of wheel speed is sampled at a constant cycle, and it is judged whether or not the edge of the sensor pulse is detected between sampling last time and that this time. When no edge of the sensor pulse is detected, the time difference between the this sampling time and the latest pulse detecting time before that time is assumed as the edge interval, and the temporary wheel speed is computed from the edge interval. The computed temporary wheel speed is compared with the wheel speed measured at preceding sampling, and when it is judged that the wheel speed is decelerated, the temporary wheel speed is designated as the wheel speed in this sampling time. When it is judged that the wheel speed is accelerated, the wheel speed in the preceding sampling is designated as the wheel speed for this sampling.

Inventor: OKU GOJI
IPC: H01J27/26
Filed: 1986-12-01
Abstract: PURPOSE:To aim at improvement in heating efficiency, by installing a current- energizing heater close to the outside of a crucible. CONSTITUTION:At the outside of a crucible 1, there is provided with a current- energizing heater 2 being made up of baking conductive compound paste, in a coil form. This current-energizing heater 2 is reached to the extent of the inside of the center aperture 1a installed in a lower central part of the crucible 1.

Title: Overcurrent protection circuit
Inventor: MARUO MASAYA
IPC: H02H3/087
Filed: 1991-08-10
Abstract: PURPOSE:To make it possible to give temperature compensation without changing the rated current value for circuit retaining even though the temperature used is changed by reducing the base current of a junction transistor with the increase in the temperature. CONSTITUTION:The minimum breaking current of an overcurrent breaking circuit comprising N-type FETs 2 and 3 and P-type FET 4 connected between the collector and base of a junction transistor 1 becomes a slightly large current value at room temperature and a large current at low temperature relative to the current value at high temperature. Because of this, the current amplification factor of the junction transistor 1 is large at high temperature and small at low temperature; but the minimum breaking current value of the base current flowing to the base from the collector to the base through the overcurrent breaking circuit is small at high temperature and large at low temperature; and thus the minimum breaking current value of the current flowing from the collector to the emitter can be made almost constant even though the temperature used is changed.
