Title: Resistor measuring device
Inventor: HONDA HARUKICHI
IPC: G01R27/08
Filed: 1980-09-09
Abstract: PURPOSE:To obtain the true resistance value of a resistor to be measured irrespective of the value of cable resistances by subjecting the resistor to be measured to a constant current and constant voltage excitation and storing the respective output voltage then measuring the resistor through operation processing. CONSTITUTION:When switches S1, S2 are opened and a driver circuit 12 excites R by the constant electric current I=E/R, a voltmeter 3 indicates e2=RI+rI. Next, when the switches S1, S2 are closed and the driver 12 excites the R by the constant voltage value E, the voltmeter 3 indicates e3=[(R+r)/(R+2r)] E. If a cable resistance (r) is erased by using te values e2, e3, the value of R is determined as R=(e2/I)X[2-(E/e3)]. Hence, the e2, e3 are temporarily stored in two memories 9, after which the operations conforming the above-mentioned equation is carried out by an oprator 10 and the results are displayed by a display device 4, whereby the true resistance R is measured without being affected by a cable resistance (r).

Filed: 1990-05-15
Abstract: PURPOSE:To have the effect of noise removal and after lessing mounting steps, reduce mounting space as well by making up a piece of an electronic component through the combination of a ferrite material and a resistor into a single electronic component. CONSTITUTION:An electronic component 1 is composed of a cylindrical ferrite material 2, a resistor 3, and a pair of lead wires 4 and 5 acting as terminal parts. When an input signal passes both lead wires 4 and 5 through the resistor 3, noise having high frequency that is contained in the input signal is removed by a loss caused by the ferrite material 2 and then, noise having low frequency is suppressed by the resistor 3. Although the ferrite material 2 acts on a signal having low frequency as inductance holding a high Q factor and then, the reflection of a signal takes place because of the mismatch of impedance, the reflection is reduced by the resistor 3 and no waveform is distorted.

Title: Anti-skid control device
Inventor: MATSUDA TOSHIRO
IPC: B60T8/66
Filed: 1989-05-19
Abstract: PURPOSE:To prevent wrong action in anti-skid control by memorizing the wheel speed of driven wheels at the deceleration starting point, restricting the wheel speed of driving wheels, at the time of exceeding the storage speed, to the wheel speed storage value, and computing the false speed on the basis of the wheel speed selection value. CONSTITUTION:When wheel spin is not-generated to driving wheels in the non-braking running state, the wheel speed detection values between the driven and driving wheels detected by a first and a second wheel speed detecting means are approximately equal, and selection is performed by a wheel speed selecting circuit. On the basis of this, the false speed is generated at a false speed computing means, and anti-skid control is started at a damping pressure control means on the basis of the false speed and each wheel speed detection value. At this time, the wheel speed to be the reference at the time of the driven wheel starting deceleration is successively memorized by a memory, and when wheel spin is generated to the driving wheel or slip is generated to the driven wheel, the second wheel speed detection value is restricted by the wheel speed storage value, thus suppressing the climb of the false speed accompanied by the wheel speed detection value of the driving wheel. Wrong action in anti-skid control can be thus prevented.
