Abstract: PROBLEM TO BE SOLVED: To make it possible to move a stage in a prescribed direction and to position a substrate to be treated by converting the moving action of a moving member by driving of a drive shaft to the moving action of the stage according to the inclination of a tapered part. SOLUTION: When a ball screw shaft 25 is rotated by the drive of a drive motor 23, a ball screw nut 27 moves on a shaft according to the rotating direction and rotating quantity thereof and a housing 28 integral therewith is guided by a rectilinearly moving guide and is moved in an X direction. At this time, the tapered part 30a of an intermediate member 30 has a prescribed inclination with respect to the axial direction X of the ball screw shaft 25 and the moving direction of the housing 28 is limited to the axial direction X of the ball screw shaft 25 by the rectilinearly moving guide. The moving action of the housing 28 in the X direction is, therefore, converted to the moving action of the Y state 15 according to the inclination of the tapered part 30a. The Y stage 15 may be moved in a Y direction by the drive of the drive motor 23.

Abstract: PURPOSE: To provide an ultrasonic output circuit which drives a piezoelectric vibrator by the half-wave voltage of an AC power supply. CONSTITUTION: The half-wave voltage that is supplied from an AC power supply 1 and rectified by a half-wave rectifier 2 is applied to a piezoelectric vibrator 4 via a resistor 3. At the same time, the half-wave voltage is supplied to a control circuit 43 and an ultrasonic oscillation circuit 37 via a resistor 9 as the DC voltage of a power circuit 20 that is smoothed by the smoothing capacitors 15 and 19. Then a gate transistor TR 22 is turned off for a period equal to the pulse width that is decided by the resistance 21 of the circuit 43 and the differential multiplier of a capacitor 41. Then the circuit 37 oscillates to actuate an output circuit 14. The ultrasonic wave is generated by the vibrator 4 only when the circuit 37 operates.  In such a constitution of an ultrasonic output circuit, the ultrasonic wave can be oscillated and outputted from the vibrator 4 when the opening phase and time of the TR 22 of the circuit 37 are controlled. Thus the circuit 20 needs neither output transformer nor smoothing capacitor, and the device size is also redued.

IPC: H04N5/10
Filed: 1990-06-08
Abstract: PURPOSE:To prevent malfunction of a vertical synchronizing signal separation circuit by providing a 1st integration circuit integrating a composite synchronizing signal and outputting an integration signal and a comparator setting a threshold level cutting a signal whose pulse width is less than that of a horizontal synchronizing signal and receiving the integration signal. CONSTITUTION:A comparator means 38 set with a threshold level cutting off a signal whose width is that of a horizontal synchronizing signal is provided to a pre-stage of a vertical synchronizing signal separator circuit 12. Thus, at the input of a horizontal synchronizing signal, a signal inputted to a composite synchronizing signal input terminal 24 is integrated by an integration circuit 36 and since a reference voltage of the comparator 38 is set to a V1, the comparator 38 gives a high level output. That is, the signal component whose pulse width is less than that of the horizontal synchronizing signal is cut off by the comparator means 38 and the result is fed to the vertical synchronizing signal separator circuit 12. Thus, even when a vertical synchronizing signal with a narrow width is inputted, no malfunction is caused.
