Title: Power supply for electric dust collector
Inventor: MITSUSAKA TOSHIAKI
IPC: B03C3/68
Filed: 1987-05-23
Abstract: PURPOSE:To avoid a condition in which wire is thinned by arc heat or cut at a place of discharge wire spark generation which forms a discharge electrode by providing a control means to control a direct current bias voltage and an output of high voltage pulse separately. CONSTITUTION:An alternating current voltage from an AC power supply 4 is subjected to phase control and boosted. This voltage is applied between a discharge electrode 30 and a dust collection electrode 32, and at the same time, it is charged into a capacitor 14. This charged voltage is discharged in pulse form through synchronization of the voltage to the voltage cycle of the AC power supply 4 by the turning ON of a switching element 22. At that time, a high voltage pulse generated is overlapped with a DC bias voltage and applied between the electrodes 30, 32. As a result, no electric power is supplied between the electrodes 30, 32 from the power supply 4, if a spark generates at the time of application of a high voltage pulse between the electrodes 30, 32, neither any arc heat generates. For this reason, the thinning and cutting of discharge wire in the discharge electrode 30 due to arc heat does not occur.

Title: Color recording method
Inventor: NOAMI TSUNEO
IPC: G03G15/01
Filed: 1987-05-26
Abstract: PURPOSE:To stabilize the recording density, and to execute color recording of high speed and a high picture quality, by making the polarity of a toner uniform and electrifying it to a high potential in a second and a third electrification processings. CONSTITUTION:When an electrification processing of the same potential and the same polarity as a first electrification processing is executed, a positive ion is radiated to the whole surface of a photosensitive body 1 and a toner image, the polarity of the toner image is inverted to a positive polarity, and electrified to a prescribed potential. Subsequently, the third electrification processing of the opposite polarity to the first electrification processing is executed. That is, a negative ion is radiated to the photosensitive body and the toner image. As a result, the potential of the photosensitive body drops a little, and the polarity of the toner image is inverted to a negative polarity again. In such a way, the polarity of a toner is made uniform, and re-electrification is executed by a sufficiently high potential, thereafter, in a second exposing part 20, a second electrostatic latent image corresponding to a red part R is formed. It is developed by using, for instance, a red toner of positive electrification by a second developing device 6. In such a way, the picture quality is stabilized, and even if an image forming optical system is used for the second exposing part, recording having a sufficiently high picture quantity can be realized.

Title: Method and system for removing crosstalk in thin film transistor matrix address type liquid crystal display
Inventor: DONARUDO AARU KIYATSUSURUBERII
IPC: G02F1/133
Filed: 1988-05-27
Abstract: PURPOSE: To remove crosstalk clue to parasitic capacity by impressing a required voltage level from a data signal to a data line for a 1st period in the period of a scanning line energization signal, impressing a correction voltage level for a 2nd period so as to supply almost fixed RMS voltage during the 1st and 2nd periods. CONSTITUTION: A crosstalk correction method indicated in the period T1 +T2 is applied to binary display. Namely when a scanning line (n) is in an active state (the first half of the period T1 ), '1' is written in pixel electrodes. Since the scanning line (n) is not in the active state in the latter half of the period T1 , writing in the pixel electrodes is not executed. In the case of writing a binary value '0' in the same pixel cells in the period T1 , a reverse state is generated. Thus fixed RMS voltage is supplied to a data line (m) during the period T1 . Consequently crosstalk can be removed.
