IPC: H04N5/335
Filed: 1982-12-14
Abstract: PURPOSE:To make a signal integration time of all picture element cells equal to each other by constituting the picture element cell by a photosensing and readout transistor(TR) and a TR resetting the optical charge stored in its gate region. CONSTITUTION:The sources of photosensing/readout SIT 21-1, 21-2... of the picture element cells 20-1,20-2... are connected to a source voltage Vs via a line 41 and the drain is connected to horizontal selecting lines 44-1, 44-2.... When the photosensing/readout SIT and the reset SIT of each picture element cell are both in non-selecting state, a part of a signal charge stored in the photosensing/ readout SIT passes through a channel region of the reset SIT and flows into a reset voltage Vg1 and no picture element cell is conductive in undesirable way. The picture element information is read out by giving a voltage to a vertical selecting line 42-1 and giving a pulse to a horizontal selecting switch 46-1 so as to select the SIT 21-1 of the picture element cell 20-1.

Title: Manufacture of ceramic capacitor
Inventor: HIGUCHI YUKIHIRO
IPC: H01G13/00
Filed: 1992-08-17
Abstract: PURPOSE:To achieve that a ceramic capacitor whose characteristic value is not irregular and whose characteristic is high is manufactured at high yield by preventing the lack of uniformity of a baking operation in a method wherein the ceramic capacitor is manufactured by using a dielectric ceramic composition containing a high-vapor-pressure oxide such as lead oxide or the like. CONSTITUTION:When a molded body 3, for ceramic capacitor use, which contains a high-vapor-pressure oxide is baked, its surface and its rear surface are covered with sheets 2A, 2B for baking use, it is burnt out in the air and, after that, it is burnt in a hermetically sealed porcelain container 4. Consequently, since the surface and the rear of the molded body 3 are covered with green sheets of a high-melting-point inorganic oxide in required minimum quantities, it is possible to prevent that the high-vapor-pressure oxide such as lead oxide or the like contained in the molded body 3 is scattered in its baking operation. As a result, an atmosphere at the inside of the ceramic container 4 becomes uniform, it is possible to prevent the lack of uniformity of the baking operation at the inside of the 'n container 4. As a result, the sintering density of the molded body becomes uniform, and an irregularity in the characteristic value of an obtained ceramic capacitor is eliminated.

Abstract: PURPOSE: To reduce the width of both a horizontal, fixed plate and a movable plate so as to enhance workability by forming both plates in such a manner that a pair of (right and left) movable plates are wider than a pair of (right and left) horizontal, fixed plates and by supporting the movable plates eccentrically with a central shaft member. CONSTITUTION: A pair of (right and left) horizontal, fixed plates 4, which are ascended/descended by the driving force of a lift cylinder 2, are fixed to the upper end part of a ram 3. The horizontal, fixed plate 4 is long, but its width is not so larger than the diameter of the ram 3. Two pairs of (right and left) movable plates (four pieces in total), which rotate horizontally and symmetrically, are supported at both end parts of the horizontal, fixed plates 4 via a central shaft member 6. These movable plates 5 are formed wider than the horizontal, fixed plates 4, respectively, and supported by the central shaft member 6 eccentrically. With this contrivance, the width of both horizontal, fixed plate 4 and movable plate 5 can be narrowed. Accordingly, the area, which is shaded by these members 4, 5, can be reduced, thereby enhancing the workability.
