摘要： PURPOSE: To maintain the rotating speed of a motor constant by repeatedly stopping the supply of a drive voltage via a switching circuit in a short time, detecting the counterelectromotive force during the stoppage and feeding it back, thereby purely detecting only the counterelectromotive force.
CONSTITUTION: The output of a switching circuit which includes a pulse generator 41 is applied to a drive circuit 2, the supply of the drive voltage is repeatedly stopped in a short time, thereby driving a motor 1. The counterelectromotive force of the motor 1 is detected by a detector 5 during the stopping period of supplying the drive voltage, and fed back through a sample-holding circuit 52. The feedback signal is compared by the set value, thereby controlling the motor 1. Accordingly, since the counterelectromotive force when the motor current is not flowed is utilized, the influence of the resistance component is not presented, but only the counterelectromotive voltage can be purely detected, and the rotating speed can be stably controlled without error.

摘要： PURPOSE:To perform a stable rotating speed control by producing as a rotating speed signal the peak value of an absolute value signal of the signal which is obtained by differentiating the rotor position detection signal of a brushless motor, thereby accurately collecting the speed variation in the short range of a rotor. CONSTITUTION:A detection signal from a rotor position signal detector 3 is inputted as position signals phiP1, phiP2 through an amplifier 6 and a normal/reverse converter 7 to a gain controller 8 and a rotating speed signal generator 9. The signals phiP1, phiP2 are differentiated by an absolute value converting function of the generator 9, and superposed to become an absolute value signal, and its peak value is produced by a signal selector 9a to become a rotating speed signal. This signal is compared by an error amplifier 11 with the set signal from a rotating speed controller 10, the resistance values of resistor r1, r2 of a gain control circuit 8 are varied by the error signal, and controlled in gain, and a motor drive signal is outputted.

摘要： PURPOSE: To take an accurate and speedy diagnosis by converting the depth of a cecum into a signal output through a linear sliding type vaviable resistor.
CONSTITUTION: A probe 1 incorporates the linear sliding type variable resistor 11 applied with a constant voltage E and a voltage V having linear relation to the measured depth of the cecum is led out as the signal output. An arithmetic part 3 converts a digital signal from an A/D converter 2 into data for display, which is stored or outputted on a display part 6 by the operation of a foot switch 4 together with a tooth number. An output part 6 prints out the measurement result on a printer 7 or display it on a CRT display device 8. For this purpose, the tip of the probe 13 of a probe body 1 is inserted into the cecum until it abuts to the bottom part and a slider 15 is operated to bring the tip part of the probe 13 into contact with the edge of the gum. Thus, the resistance value corresponding to the length of the tip part of the probe 13 into the cecum, i.e. the depth of the cecum is obtained and lead out through a lead wire 19 as the signal output.

摘要： PURPOSE:To enable to maintain a motor at a constant rotating speed by detecting the rate of change of the set voltage for controlling the rotating speed of the motor, and maintaining by a sample-holding circuit the set voltage to the value immediately before the abrupt change when the rate of change abruptly varied. CONSTITUTION:The rate of change of the output of a set voltage generator 1 which controls the rotating speed of a motor 8 is detected by a detector 2, and when it exceeds the predetermined level to abruptly change, a signal is outputted through a pulse generator 3, and supplied to a sample-holding cricuit 5.
