Abstract: PURPOSE:To reproduce a projected picture having always correct color by flowing a current in response to the change in a high voltage current of a cathode ray tube to convergence coil to prevent the shift of static convergence due to the change in the brightness of the screen. CONSTITUTION:A resistor 17 for detecting high voltage current is connected to a cold end of a high voltage winding 14 of a high voltage generating transformer 11 and the voltage across the resistor is smoothed by a capacitor 18 and fed to a convergence amplifier 21 via resistors 19, 20.

Title: Apparatus and method for suppressing vertical magnetic filed for length-wise recording
Inventor: MAIKERU ERU MARARII
IPC: G11B5/02
Filed: 1989-06-19
Abstract: PURPOSE: To improve recording density by suppressing vertical magnetic field components with opposing components generated as an auxiliary through a magnetic field path and thereby minimizing the vertical components near the air gap of a head. CONSTITUTION: A recorder drive signal is supplied to a vertical magnetic field backing coil 42 other than to a right angle coil 40, generating a magnetic field that establishes the free end of a first and a second pole piece as the common magnetic pole of the secondary magnetic field indicated by the secondary magnetic line of force 48. In other words, the phase shifting of the recorder drive signal, opposing to the one by the right angle magnetic field indicated by the right angle magnetic line of force 46, establishes the polarity of the secondary magnetic field indicated in the free end of the second pole piece 36 by the secondary magnetic line of force 48.  The secondary magnetic field indicated by the secondary magnetic line of force 48 through its long magnetic path is provided with an essentially vertical component from the second pole piece 36, this vertical component opposing that of the right angle magnetic field indicated by the right angle magnetic line of force 46. Thus, the vertical magnetic field components can be reduced by adjusting the amplitude ratio of the recorder drive signal which is supplied to the right angle coil 40 and the vertical magnetic field backing coil 42.

Title: Precision guide stage device
Inventor: ITO KAZUHIRO
IPC: B23Q1/34
Filed: 1990-06-15
Abstract: PURPOSE:To enable high accuracy positioning of a precision stage by absorbing accuracy error which is caused by two dimensional drive means by a cross spring, and supporting the posture of the precision stage by an air pad and guide reference plane in a semiconductor manufacturing device. CONSTITUTION:This stage device has a base 35 which has guide reference plane, a precision stage 28 which is supported on the guide reference plane via an air pad 24, a two dimensional drive means which can move in the guide reference plane and the face of parallel base 11, and a cross spring 20 which makes the two dimensional drive means engage with the precision stage 28. Consequently, since the precision stage 28 is driven by the two dimensional drive means via the cross spring 20, it is driven by the two dimensional drive means with respect to the direction in two dimensional face, but the cross spring 20 absorbs error with respect to the direction other than the direction in two dimensional face. For this reason, the precision stage 28 can perform high accuracy movement along the guide reference plane.
