Abstract: PURPOSE:To obtain an inspection plate generation device which can easily form the complicated pattern of a fixed board without the escape of air by permitting a fixed board mainbody and a base plate to sandwich a soft pattern forming plate and permitting a restriction member to restrict the size of a gap. CONSTITUTION:A device is constituted by providing the fixed board mainbody 306, the base plate 312, the pattern forming plate 310, the restriction member 364 and an adsorbing device 326 for a fixed board part. Since the pattern forming plate is formed by a soft member in such constitution, the pattern can be formed by punching work and work becomes facile. Thus, work is prevented from becoming troublesome even if the sizes of photosensitive materials increase. The pattern forming plate is sandwiched by the fixed board mainbody and the base plate, and the fixed board 301 of three layer structure is formed. Since the size of the gap between the fixed board and the base plate is restricted to the prescribed size in the restriction member 36 at that time, the soft pattern forming plate is maintained to a prescribed thickness and the pattern space of high air tightness can be obtained. Consequently, the complicated pattern of the fixed board is easily formed without the escape of air.

Abstract: PURPOSE:To prevent the density of a first image from being lowered by providing a preliminary electrostatic charge means which previously preliminarily electrostatically charges an image forming area on a latent image carrier so that triboelectrified charge on the surface of the latent image carrier is negated. CONSTITUTION:The preliminary electrifying means (an electrostatic charger 4 or a transfer charger 8 used also as electrostatic charge means) by which the image forming area on a photosensitive body 1 is previously preliminarily electrified so as to negate the triboelectrified change on the surface of the body 1 generated by allowing a cleaning member to rub on the surface of the body 1 when the first image is formed after the standby of a device is provided.

Title: Driving circuit for display device
Inventor: IEMOTO TAKAAKI
IPC: G02F1/133
Filed: 1991-06-10
Abstract: PURPOSE:To securely turn OFF a TFT in an OFF period and to suppress the deterioration of the display device by providing a means which superposes an AC signal in phase with another AC signal on a driving signal applied to a scanning electrode. CONSTITUTION:When the TFT connected to the scanning electrode is turned ON, a voltage pulse VDD is selected, but in its OFF period, a voltage pulse VEE is selected. In the OFF period, a scanning pulse is in phase with an opposite voltage and the amplitude of the scanning pulse is equal to that of the AC component + or -VC of the opposite voltage. In a gate-OFF period, variation in the potential of a drain electrode based upon the AC component + or -VC of the opposite voltage is canceled by the amplitude of the scanning pulse and the difference voltage between the drain electrode opposite voltage and the scanning pulse becomes invariably constant, so a voltage applied to the gate of the TFT is constant and its value is determined by the difference voltage. The value of this difference voltage is optionally set, so the best OFF voltage can be applied and the TFT can securely be turned OFF.

Filed: 1986-06-13
Abstract: PURPOSE:To increase a growth rate in the direct thermal nitriding of Si by conducting direct thermal nitriding after the thermal oxidation of an Si substrate and the etching removal of a thermal oxide film. CONSTITUTION:When an Si substrate 1 is thermally oxidized and a thermal oxide film 2 is grown, a layer 3 in which there is interstitial Si in high concentration can be formed near an Si surface. The layer 3 is left even by removing the thermal oxide film at a low temperature, and increases the rate of direct thermal nitriding of Si after the removal of the thermal oxide film. An Si direct thermal nitriding film 4 acquired in this manner is used as an insulating film or an anti-oxidizing film. Accordingly, the rate of direct thermal nitriding of Si can be increased by simple treatment, and the method is available as an insulating-film or anti-oxidizing-film forming method.
