Title: Plasma address liquid crystal display panel and its channel subassembly
Inventor: KEVIN J IRUSHISHIN
IPC: H01J17/48
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To ameliorate crosstalks and to improve the contrast ratio of display by forming plural island-shaped members of a transparent conductive material on one surface of a cover sheet covering a first channel. SOLUTION: Respective element panels 28 have the discrete island-shaped members 40 of the transparent and electrically conductive material on the rear surface of the cover sheet 6. These plural island-shaped members 40 line up as rows and since the members are conductive, there are no fluctuations in the charge density on the regions of the island-shaped members. Then, if plasma is formed within the channel 20j by using the display panel, the charge density on the upper side of the rear surface of the cover sheet 6 is uniform within the panel elements 28i ,j , and the electric fields in volume elements 10i ,j are uniform as well. The charge density on the upper side of the rear surface of the cover sheet 6 is uniformly maintained within the panel elements 28i ,j after the annihilation of the plasma.  The value of the charge density remains unchanged until the plasma is generated within the channel 20, in the next frame of video signals.

IPC: G11B11/10
Filed: 1985-11-20
Abstract: PURPOSE:To reduce the size of the titled device by arranging a coil so as to surround a permanent magnet to be an external magnetic field forming means and rotating the permanent magnet by 180 deg. in a required direction by repulsion force due to a magnetic field generated by current supply into the coil and a magnetic field formed by the permanent magnet. CONSTITUTION:When a magnetic chip 12 is arranged on any one of the 1st-4th quadrants, magnetic state around the permanent magnet 3 is changed from balanced state around the X axis, so that the magnet 3 is inclined from the X axis as shown in a dotted line. Since the magnetic state around the magnet 3 is unbalanced from the center axis 9, the magnet 3 always tries to rotate as shown in the dotted line in the no current supply state into the coil, and thereby, when there is no magnetic chip 12, i.e. when the magnetic state is balanced, the magnet 3 is prevented from a trouble such that the magnet 3 is positioned on a dead point and interrupted from being inverted inspite of current supply into the coil to invert the magnet 3 and precise inverting operation can be attained.
