Abstract: PROBLEM TO BE SOLVED: To provide an internal circuit with thinner film by heating metal material powder, which is dispersed to a dispersion medium for generating a conductive paste, made into sheet for generating a ceramic green sheet, and laminated/press-contacted for baking. SOLUTION: A metal material powder is heated in open atmosphere, the water content in the metal material powder is evaporated for dehydration, impurities and foreign substances are burned up, oxide film is formed on the surface of the metal material powder, and the metal material powder is mixed with a binder of a dispersion medium to generate a conductive paste. Then, a ceramics green sheet is formed of a slurry, a specified via hole 2a is formed, a conductive paste is screen-printed on one surface with a specified pattern, thus an internal circuit 3 of specified thickness is formed. They are laminated/ press-bonded in plural numbers to get a sheet laminating body, and an external circuit 4 is screen-printed on a bottom surface with the conductive paste, which is eventually sintered in a reducing atmosphere.  Since an oxide film is formed at sintering, no crack etc., occurs at the internal circuit even with a thinner film thickness of the conductive paste.

Abstract: PURPOSE:To improve the active matrix substrate used for an active matrix type liquid crystal display device. CONSTITUTION:In the active matrix substrate 1 in which a picture element part 2 containing a thin film transistor as a switch and peripheral circuit parts 31, 32 constituted by containing the thin film transistor are formed on the substrate 1, the thin film transistor of the picture element part 2 consists of an offset structure or an LDD structure, and the thin film transistor of the peripheral circuit parts 31, 32 consists of a structure in which end parts of source and drain areas 6S, 6D and an end part of a gate electrode are matched or superposed to each other. Since the thin film transistor of the picture element part 2 consists of the offset structure or the LDD structure, a turn-off current can be reduced, and on the other hand, since the thin film transistor of the peripheral circuit parts 31, 32 consists of a regular structure (structure in which the gate electrode 8 and the source and the drain areas 6S, 6D are matched or superposed to each other), a fall of the turn-on current can be prevented.

Title: Electrostatic charging device
Inventor: MIYAGAWA SEIICHI
IPC: G03G15/02
Filed: 1989-12-29
Abstract: PURPOSE:To restrain an ozone generating quantity and to prevent unevenness in electro static charging on a surface to be electrostatically charged by disposing a resistance functioning as a discharge electrode and having a part opposite to a body to be electrostatically charged where a voltage is impressed on an electrostatic charging blade. CONSTITUTION:A photosensitive body 1 rotates clockwise and passes through the leading edge part of a blade substrate 11 which abuts on the surface of the photosensi tive body 1. At this time, the voltage which is obtained by superposing an AC on a DC by a current 13 is impressed between a lead electrode 14 and the conductive base substance 2 of the photosensitive body 1 functioning as the counter-electrode of the lead electrode 14. Since the voltage is impressed on the resistance 15 which is disposed on the electrostatic charging blade part while functioning as the discharge electrode in such a way, corona discharging occurs between the resistance 15 and the photosensitive body 1, and the surface of the photosensitive body 1 is uniformly electrostatically charged to a prescribed polarity. Thus, there is no possibility of the occurrence of the unevenness in electrostatic charging in a stripe state on the surface of the photosensitive body, so that the ozone generating quantity and the deterioration of the photosensitive body can be restrained.
