Abstract: PURPOSE: To obtain stable driving performance in a light load region and acquire sufficient output in a high load region by setting the valve overlaps of cylinders at the working side in relatively small value as compared to cylinders at the stopoage side.  
     CONSTITUTION: A cam shaft 16 is formed in such a manner that a shape of the cams of cylinders A, B, C at the working side and a shape of the cams of cylinders D, E, F at the stoppage side differ. To be concrete, the shapes of each cam of the cam shaft 16 are made up to ensure that an exhaust valve lift characteristic X 1  of the cylinders A, B, C at the working side and the intake valve lift characteristic Y 1  are shown as the figure to an angle of a crank while an exhaust valve lift characteristic X 2  of the cylinders D, E, F at the stoppage side and the intake valve lift  characteristic Y 2  are shown as the figure. That is, the valve overlaps of the intake  and exhaust valves of the cylinders A, B, C at the working side are set in comparatively small value (or zero) capable of ensuring stable combustion in a light  load region while the valve overlaps of the cylinders D, E, F at the stoppage side  are set in comparatively large value capable of ensuring sufficient output in a high load region.

IPC: G03C7/44
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To stabilize photographic characteristics when photosensitive materials for photographing with emulsions having different silver halide compositions are mixedly processed by varying the concentration of a replenisher for development and the amount of the replenisher replenished per unit processing area. SOLUTION: A processing area of a high silver chloride photosensitive material 16 is calculated by an operating means 31 from the width of the photosensitive material 16 sensed with a sensor 26 and the amount of the photosensitive material 16 conveyed in a control means 32 and the processing area is cumulatively stored in a memory 28.

Title: Pnpn switch
Inventor: YOKOYAMA JUNICHI
IPC: H01L29/74
Filed: 1989-06-23
Abstract: PURPOSE:To easily allow both characteristics of a breakover voltage VBO and a breakover current IBO to fall within specifications by connecting a base region to a cathode electrode via the same conductivity type diffused resistance layer as that of the base region. CONSTITUTION:When a P-type base region 2 made of a N<-> type substrate is formed with a P-type base region 2, a P-type diffused resistance layer 9 is simultaneously formed. When a cathode 5 is applied by a negative voltage and an anode electrode 7 is applied by a positive electrode, a breakdown occurs at the corner of the layer 2. A potential difference is generated across the layer 9. Therefore, the potential of the layer 2 becomes higher than that of a cathode layer 1. When the potential difference becomes about 0.5V, an element is turned ON. A current necessary to generate a potential difference of 0.5V across the layer 9 is a breakover current IBO, and there is a relation of IBO=0.5V /R[A]. The value of the R can be easily set to 5kOMEGA or more, and the IBO can be easily suppressed to 100muA or less.

Title: Dynamic pressure bearing for vacuum
Inventor: YASUI KEIGO
IPC: F16C17/02
Filed: 1994-07-14
Abstract: PURPOSE:To provide a dynamic pressure bearing for a vacuum to prevent the occurrence of leakage of a lubricant through simple structure. CONSTITUTION:A gap between the bearing part 5 of a rotary member 2 and the bearing part 6 of a fixing member 1 is filled with a lubricant 7 for a vacuum. The surface layer of the bearing part 5 of the rotary member 2 is formed of an oxidizing zone 10 having wettability against a gallium alloy 7 lower than that of the bearing part 6 of the fixing member 1. The gallium alloy 7 on which the centrifugal force of the rotary member 2 is exerted is repelled by the edge part 12 of the bearing part 5 to suppress leakage of the gallium alloy 7 to the outside of the bearing part 5. Further, since the oxidizing zone 10 having low wettability is formed at the edge part 12 of the bearing part 5 of the rotary member 2, there is no need to form an extension part to a bearing part 5 unlike a conventional embodiment.

IPC: H01J9/44
Filed: 1989-06-23
Abstract: PURPOSE:To remove a needless electron generation source with good efficiency by impressing a magnetic field on a cathode-ray tube externally for making needless electrons to collide with a high-voltage electrode adjacent to the needless electron generation source. CONSTITUTION:Since field emission 33 emitted from a projection part 32 of a peripheral part of a hole 28 of a second grid 15 is deflected in the peripheral direction by a powerful magnetic field 34 to be impressed from outside to collide with an electrode part near a hole 29 of a third grid 14, the colliding point part is heated. At this time, the third grid 14 is melted to emit a large amount of metal gas. The emitted gas bombards field emission 33 accelerated to high speed to be separated into ions and electrons for being accelerated by a high electric field impressed between electrodes so as to make needless electrons 33 to again bombard the electrode for emitting more gas so that a process such as activation of BaO at the tip of a projection part 32 and high-voltage treatment may be repeated. Discharge is generated near the projection part 32 by repeating such a phenomen to consume big energy and to smooth the projection part.
