Title: Electrophotographic device
Inventor: SUZUKI MANABU
IPC: G03G15/02
Filed: 1987-04-07
Abstract: PURPOSE:To prevent unevenness from being generated on the surface of a photosensitive body, and to execute a uniform electrification by providing a first electrifying means for electrifying the photosensitive body, and a second electrifying means. CONSTITUTION:When a photosensitive drum 1 rotates in the direction as indicated with an arrow B, the drum surface part passes through a main electrifying part 2 by following up its rotation, by which it is electrified to a uniform potential. On the other hand, the surface part of the photosensitive drum 1 after a toner has been transferred advances to an auxiliary electrifying part 6 consisting of a comparatively miniature and inexpensive conductive brush, and electrified until the part which has become a low potential by an exposure, and the part which is not exposed but has become a high potential become a prescribed potential difference. Subsequently, by passing through a cleaning part 7, a residual toner which has not been transferred to a form 9 to be transferred by a transfer part 5 is cleaned, and said surface part is electrified to a uniform potential again by the main electrifying part 2. In such a way, the photosensitive body 1 can be electrified uniformly and the image formation of an object to be photographed is executed satisfactorily.

Title: Semiconductor device
Inventor: TAKANASHI MIKIO
IPC: H01L21/331
Filed: 1987-04-06
Abstract: PURPOSE:To prevent a noise characteristic of a transverse type bipolar transistor from being deteriorated, by disposing a gettering region, which is shallow and of high-concentration and of the same conductivity type as a base and contains many crystal defects, directly under a base regional surface. CONSTITUTION:This transverse type bipolar transistor is provided with the following parts: a region 3 where N type burial 2 is performed on a P type substrate 1 and next N type epitaxial growth is performed, an emitter region 4 and a collector region 5 which are formed by introduction of P type impurities, and an electrode drawing part 6 which is formed in a base region (an N type epitaxial region 3) by the introduction of N type impurities. Further, N type impurities are introduced to be of high-concentration, and resultingly a gettering region 7 which contains many crystal defects is disposed on the base region so that it is not in contact with the emitter region 4 and the collector 5. Since a region which is of high-concentration N type and contains many crystal defects is disposed directly under a surface of the base region in this invention, a gettering effect of heavy metal ions which serve as centers for generation/recombination of carriers is generated and so a noise characteristic can be improved.

IPC: H01L21/56
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To delivery much flow by high repeatability irrespective of the viscosity of material and increase the accuracy of fluid delivery irrespective of an entry of air into and a variation in viscosity or temperature of fluid. SOLUTION: A stepped plunger 44 extends inside a pump chamber in the axial direction, and the first section of the plunger 44 of such a size that is passes through the first directional seal 32 is positioned at the first directional seal 32. Also the plunger 44 is movable, and its first section is moved to an outlet so as to close an internal volume at a second seal 34. The second section of the plunger 44 is considerably smaller in lateral cross sectional dimensions than the inner diameter of the second seal 34, and promotes the removal of fluid from the internal volume in cooperation with a port during the initial changing into the pump chamber and preliminary operations for air bleeding. After the charging and air bleeding preliminary operations, the plunger 44 exhausts the fluid inside the pump through the nozzle by a positive volume forcing. This is performed at a large fluid flow and high repeatability irrespective of the viscosity of material and a variation in temperature or viscosity.
