Inventor: TANAKA KEIICHI
IPC: H02K41/03
Filed: 1999-01-14
Granted: 2000-09-11
Abstract: This invention utilizes the electromagnetic interaction in between the magnetic pole elements (45X1, 45X2, 45Y1, 45Y2) for producing a self reaction force for offset, and an electrical coil (63) as a stator, so as to offset the reaction force applied to the stator (60) from the driving of the movable rotor (51) without using a yoke piece, thereby making the magnetization direction towards the stator. A combination of the magnet which is intersected with the direction of produced magnetic flux is used to construct a magnetic pole element for the movable rotor to reduce the weight of the movable rotor. Therefore, even when the movable rotor is moved under high speed, it is still able to prevent the vibration of the stator, thereby enabling the loaded testing material (W) to be moved continuously under a high speed and to proceed a high precise positioning control.

Title: High voltage power supply circuit
Inventor: OTA HIROYUKI
IPC: H04N3/185
Filed: 1999-04-28
Granted: 2001-09-21
Abstract: A speed-up circuit 10 is connected to a detection line 6 for feeding back the high voltage detection value of a high voltage detection circuit 5 to a high voltage stabilizing circuit 1. When a power supply switch is turned on, since a PNP transistor 12 of the speed-up circuit 10 is turned on, a resistor 11 is connected to the detection line 6, so that the high voltage detection value is reduced forcedly. Accordingly, the high voltage stabilizing circuit 1 increases the peak value of a flyback pulse generated by a resonance-type power supply circuit 2 to output higher high voltage thereby to shorten the rising time of the high voltage output supplied to the anode of a CRT. After the lapse of the predetermined time from the turning-on of the power supply switch, since the terminal voltage of a capacitor 13 having been charged through a resistor 14 exceeds almost the voltage at a point A, the PNP transistor 12 is turned off, so that the resistor 11 is separated from the detection line. Accordingly, the responsibility of the flyback pulse is prevented from being degraded at the time of the abrupt change of the load of the CRT.

Title: Method and apparatus for processing video pictures, especially for false contour effect compensation
Inventor: CORREA CARLOS
IPC: G09G3/28
Filed: 1999-07-30
Granted: 2001-08-21
Abstract: With the new plasma display panel technology new kinds of artefacts can occur in video pictures. These artefacts are commonly described as ""dynamic false contour effect"", since they correspond to disturbances of gray levels and colors in the form of an apparition of colored edges in the picture when the observation point on the PDP screen moves. According to the invention, such an artefact is compensated by analyzing the pictures, and determining the pixels which need to be corrected. The digital sub-field code words of these pixels are replaced by corrected sub-field code words. Thereby, the correction sub-fields (C1, C2, C3) which are inserted in or omitted from the digital code word are selected under consideration of its position within the frame period for optimal results.
