Filed: 1995-03-31
Abstract: PURPOSE: To realize low vibration and low noise by moving a mover in the direction of the X-axis or Y-axis to a target coordinate point when the speed in the direction of any one axis is lower than a reference speed and then moving the mover in the direction of the Y-axis or X-axis to the target coordinate point. CONSTITUTION: At first, speeds in the direction of the X-axis and Y-axis are determined (S1). It is then decided whether the speed in the direction of the X-axis is lower than a reference speed (S2) and the speed in the direction of the Y-axis is lower than a reference speed (S3). If it is lower than the reference speed, a mover is moved by an amount of the X component to a target coordinate point A and the coordinate point of the mover is referred to A1. Subsequently, the mover is moved by an amount of the Y component to the target coordinate point A from the coordinate point A1. When the speed in the direction of the X-axis or Y-axis is not lower than the reference speed, the mover is moved, as it is, to the target coordinate point A. With such method, vibration and noise can be suppressed.

Title: Inverter circuit for high frequency heating device
Inventor: KUSUKI SHIGERU
IPC: H05B6/66
Filed: 1988-03-30
Abstract: PURPOSE:To obtain an inverter circuit of low noise by employing a constitution of a switching element of an L-C resonance circuit with a transistor and a diode connected in series. CONSTITUTION:A dc power is smoothed by flowing through a noise suppressor coil 7 and a condenser 8. A resonance condenser 9 and a transformer 10 are connected to the smoothed power source to constitute a resonance circuit of an L-C. A switching element constituted with a diode 15 and a transistor 14 connected in normal direction in series is connected in parallel to the condenser 9. The control of a dc transistor 14 is performed with a PWM control circuit 16.
