Title: Immersion treatment apparatus for substrate
Inventor: MURAOKA YUSUKE
IPC: H01L21/306
Filed: 1994-06-28
Abstract: PURPOSE:To reduce the running costs of an immersion treatment apparatus by preventing a substrate treatment apparatus for the surface treatment of a semiconductor substrate or the like from becoming large-sized and by suppressing the consumption amount of a treatment liquid. CONSTITUTION:A liquid discharge passage 42 which is drawn out from an overflow-type substrate treatment tank 1 is branched, one part is connected to a drain 43 via a liquid discharge valve 47, and the other part is connected to a treatment-liquid storage container 6 via a treatment-liquid collection valve 44 as a treatment-liquid collection passage. Whenever, surface treatments with a plurality of kinds of treatment liquids are conducted, a treatment liquid which has overflowed from the substrate treatment tank 1 is collected in the storage container 6 via the treatment-liquid collection valve 44, and it is circulated again to the substrate treatment tank 1 so as to be reused.

Title: Fluid injection nozzle
Inventor: TANI TAISHIN
IPC: F02M61/18
Filed: 1996-06-07
Abstract: PURPOSE: To provide a fluid injection nozzle that increases the turbulence of fluid flow so as to expedite the atomization of an injected fluid. CONSTITUTION: When a needle that can come in contact with a part of the conical slant face 262 of a valve body 26 is spaced from the conical slant face 262, fuel flows into a space formed being partitioned by the tip part curved surface of the needle 25, the conical slant face 262 of the valve body 26 and the inlet face of an orifice plate 52. The main stream of this fuel flows along the spherical surface 64 so as to be drawn to an annular groove 65 without escaping directly from orifices 54, 56, and the fuel flow becomes unstable in the space. The direction is then controlled by the orifices 54, 56, and the fuel is injected from the orifices 54, 56. The injected fuel thereby becomes fuel spray expedited in atomization.

Title: Manufacture of pipe made of carbon-fiber-reinforced concrete
Inventor: KOGO YASUO
IPC: B28B21/48
Filed: 1988-06-14
Abstract: PURPOSE:To shorten possessory hours of a mandrel by making removal of a core of the mandrel easy, by a method wherein after initial stage curing of a carbon fiber impregnated with cement water paste by winding the carbon fiber round a hollow mandrel whose diameter is enlarged by interposing an insertion material into a slit part, the insertion material is removed. CONSTITUTION:After interposition of an insertion material 2 into a hollow mandrel 1, a carbon fiber 3 impregnated with cement water paste is laminated to the mandrel 1, which is coated with a coating film 4. After progress of an initial stage curing up to a state where a main laminate can be demolded, the insertion material 2 is removed, the diameter of the hollow mandrel 1 is contracted and a core of the laminate with a progress in cure is removed. With this construction, removal of the core of the mandrel can be performed easily without having fear of damaging a pipe at a stage where the initial curing is completed. Since repeating use of the mandrel is possible, the title method is economical. A hard polyvinyl chloride pipe, polypropylene pip, fiber- reinforced synthetic resin pipe are suitable especially as the hollow mandrel 1.

Title: Feeder for picture input device
Inventor: TAZAWA AKIRA
IPC: H04N1/04
Filed: 1994-06-28
Abstract: PURPOSE:To surely insert/eject also an original having different thickness by providing a feeder with an original pressing plate for inserting an original from an insertion side magazine into an image input device body, a pair of rollers for ejecting the original to the inside of an ejection side magazine and a driving source for driving the pressing plate and the rollers. CONSTITUTION:At the time of inserting operation, rubber rollers 85 are rotated around shafts 87 in a mutually separating direction by the frictional torque of a roller pulley 82 and a lever 86. Thereby the inserting operation is executed by the pressing plate 78 and the rollers 85 are not related to the inserting operation. At the time of ejecting operation, a carriage part in the image input, device is moved in a focus direction until its center almost matches with the center of the rollers 85. Since a film mount exists on the center of the carriage part, the possibility of shifting the position in the focus direction exists and the injected mount is abutted on a feeder block 51 and can not be ejected by the rollers 85 some times. Thereby the center of the rollers 85 is deviated from the carrying face of the block 51.

Abstract: PURPOSE:To miniaturize a device and to eliminate a defect in contacting which is caused by lubricating oil scattered from a driving part by arranging electric contacts in front of a driving part constituted on the inner side of a main body. CONSTITUTION:The respective contacts are all arranged in front of a process cartridge 1 and positioned on the opposite side from a driving input gear 13 fitted on the inner side of a photosensitive drum 6.
