摘要： PURPOSE:To measure stature by one measuring person and to perform processing corresponding to statistics by providing a measurement pole with a preset band, a measurement band, one preset position reading photosensor, and two displacement reading optical sensors. CONSTITUTION:A cursor 14 is fitted through a motor-driven driving roller 16 to the measurement pole 13 stood on a foot plate 12. When the floating contact plate 20 of this cursor 14 abuts on the head of a person to be measured and moves against the energizing force of a spring 2, a limit switch 24 is turned on. Further, the cursor 14 is provided with the preset position reading optical sensor 30 corresponding to the preset belt 29 which has a reflection part 26 formed at a specific position on the foot plate 12 and two displacement reading optical sensors 34 and 35 which is formed of black painted parts 31 for reflecting no light and metallic ground parts 32 for reflecting light alternately and reads the quantity and direction of the displacement of the cursor 14 corresponding to the measurement belt 33. Stature data is measured with the outputs of those sensors and this data is read in a computer and also displayed.

摘要： PURPOSE:To readily and accurately regulate the torque/rotating speed characteristic of a motor by controlling the duty of a switching element inversely proportionally to the counterelectromotive force of the motor. CONSTITUTION:A triangular wave generator 8 generates a triangular wave having a frequency decided by R1 and C1, and an amplitude decided by R2-R4. An amplifier 10 outputs a reference voltage regulated by a variable resistor VR1. A comparator 9 compares the triangular wave with a reference voltage, and applies a pulse width control signal to an FET1. When the rotating speed of a motor M decreases to reduce a counterelectromotive force, a voltage between the drain and the source of the FET1 input to the amplifier 10 rises. Thus, a reference voltage rises, and the ON time of the FET1 increases.
