Abstract: PURPOSE: To surely detect the speed and torque of a motor by computing the sum of the wiring resistance of the motor and the internal resistance of the motor before the operation of the motor. CONSTITUTION: In the case of starting a motor M, a coil B0 is excited by an external switch. Therefore, a current flows through a line resistance r1, a shunt (s), an auxiliary resistance R and the motor M. The resistance R is sufficiently large to prevent the start-up of a motor. The line resistance r1 and the internal resistance of the motor M are computed on the basis of a current value and a voltage in the resistance R. After the measurement is made, the coil (b) of a short-circuiting relay (r) is excited by a delay time circuit T to short-circuit the auxiliary resistance R. On the basis of the measurement, the torque of the motor M from the measurement of a current is computed.

Filed: 1989-01-17
Abstract: PURPOSE:To improve a fingerprint collating rate by arranging a projecting part having a prescribed height on the whole surface of a fingerprinting part at finer pitches than that of the image resolution of a picture detecting part. CONSTITUTION:On the whole surface of a fingerprinting part 10a of a transparent substrate 10 constituting a fingerprint image input device, unevenness obtained by arranging projecting parts 10b, which are lower than the height from the trough line of the finger-print peak line, at the finer pitches than that of the image resolution of an image sensor 4 is formed. Thus even when the pressure of a specimen to push a fingerprinting surface, namely the pressure of a finger, is weak, the finger easily makes contact with the tip part of the projecting part, since the projecting part thrust a fingerprint surface, especially a fluid layer such as the sweat and grease of the peak line part, the disconnection or omission of the peak line pattern can be linked, and the unclear part of the fingerprint pattern can be eliminated. On the other hand, the picture signal smaller than the image resolution of the image sensor is not sensed. Thus the fingerprint collating rate can be increased.
