    摘要: An actuator suitable for use in a joint device for driving a robot arm or in a subject follow-up device in a video camera, etc. is designed to have a mobility of a freedom of two degrees or more and is adapted to drive a movable part directly using first piezoelectric motor elements each of which consists of piezoelectric elements (8a) having a non-ring-like configuration and an elastic body (9) and second piezoelectric motor elements (8b) each of which consists of at most one ring-like piezoelectric element and an elastic member. The actuator exhibits a simplified structure, is small and lightweight, provides a powerful driving power and has a wide range of mobility.

    摘要: A magnetic detector (Fig. 2 or 8) for detecting a magnetism present in the vicinity of or close to a magnetic wire (1, 1') circumferentially magnetized therein and an electromagnet (2) for generating an A.C. magnetic field on the basis of the magnitude of a Matteucci-effect voltage developed across the magnetic wire when the electromagnet approaches the magnetic wire. A coordinate input device (Fig. 1, 4 or 9) for detecting proximity between the electromagnet and an array of a plurality of such magnetic wires arranged in X and Y directions when the electromagnet approaches the array. A magnetic image sensor (Fig. 14) for detecting an intensity distribution of a static magnetic field to be detected and present along a longitudinal direction of the wire on the basis of a detection voltage of the wire when a plurality of such electromagnets arranged along the longitudinal direction of the wire are sequentially excited one after another.

    摘要: Disclosed is a control method and a control apparatus (7) for controlling a PWM inverter (2). The PWM inverter receives AC power and generates an AC output having a controlled frequency to be supplied to an AC motor (3). A circuit (8, 9) is provided for generating, on the basis of a given running command (ω*), a PWM signal controlling the inverter with a given sampling period, and a further circuit (10) controls the PWM signal generating circuit, whereby the AC motor generates an electromagnetic tone preselected so as to correspond to desired information when the AC motor is driven by output of the inverter controlled by the PWM signal. The above described desired information may be information representing the running state of the motor or selected music.
