Title: Plasma display panel with limited dis- charge region
Inventor: SERUJIYU SARABUAN
IPC: H01J11/32
Filed: 1990-06-25
Abstract: PURPOSE: To simplify discharging so as to reduce the loss of a light output by disposing two most proximate protruded surfaces among the two pixels of the same pair such that one belongs to an address-maintaining electrode and the other belongs to a maintenance specialized electrode. CONSTITUTION: In the same pixels, protruded portions SB1 to SB3 and SC1 to SC3 belonging to address-maintaining electrodes Y1 and Y2 and maintenance specialized electrodes E1 and E2 are disposed by being shifted and the protruded surfaces form channels C in the pixels. The average length of the channels C almost corresponds to a total value obtained by adding a distance d1 between the two protruded surfaces of the same pixel to the sum of twice the width L2 of the protruded surface and a length L1. As a result, a necessary electrode difference between the two electrodes of maintenance electrode pairs P1 and P2 is reduced to improve an operation. Further, between the two adjacent pixels, most proximate protruded portions are obtained, one belonging to the maintenance electrodes Y1 and Y2 and the other belonging to the maintenance specialized electrodes E1 and E2.  Equal potential lines a, b and c produced among these electrodes are more concentrated between the protruded surfaces and thus the level of concentration is increased more than conventionally.

Title: Energy analyzer for voltage measurement
Inventor: ITO AKIO
IPC: G01R31/302
Filed: 1984-08-09
Abstract: PURPOSE:To reduce the influence of an electron beam incidence hole and to take a precise analysis by decelerating and diverging an electron beam which is led out by a high-potential lead-out grid by a plane decelerating grid. CONSTITUTION:An electron beam 1 is supplied from the electron beam incidence hole 2 to illuminate an LSI wiring sample 3, which emits the secondary electron. The secondary electron is led out by the plane lead-out grid 6 which is provided nearby the sample 3 and applied with a high voltage from a DC power source 5 and travels to an analytic grid 4 while accelerated to a high speed. The grid 6, however, is applied with the too high voltage, so the secondary electron is concentrated on the center and all secondary electrons leak from the incidence hole 2 without passing among grids 4. For the purpose, the decelerating grid 7 consisting of the plane decelerating grid 70 and a hemispherical decelerating grid 71 is provided on the grid 6. Consequently, secondary electrons which are led out by the grid 6 with a uniform decelerating electric field produced between the grids 6 and 70 and never leaks from the incidence hole 2 of the grid 4.

Title: Brightness control limiting circuit
Inventor: IKEDA MAKI
IPC: H04N9/64
Filed: 1987-07-03
Abstract: PURPOSE:To easily set a limiter by applying the limiter to a brightness control according to the same direct current bias as the direct current level of a color difference signal output at the time of a silent signal set by the bias circuit of a demodulating circuit. CONSTITUTION:The color difference signal output is inputted to the base of a transistor TrQ5 through a color difference signal output terminal 7 from the demodulating circuit 12, a luminance signal from a luminance signal processing circuit 2 is pedestal clamped and inputted to the base of a TrQ4. The base of a TrQ4 in which the direct current bias the same as the direct current level of the color difference signal output at the time of the silent signal applies the limiter to the brightness control through a bias terminal 8 is connected from the circuit 12. The pedestal level (base potential of TrQ4) of the luminance signal is changed according to the brightness control. However, since the direct current level of the color difference signal output terminal 7 an the bias terminal 8 is equal, the base potential of the TrQ4 is not raised above the base potential of the TrQ5. Accordingly, the pedestal level of the primary color signal of an output terminal 11 has the limiter applied substantially at OV and is not lowered therebelow.
