Title: Autofocusing camera
Inventor: ISHIKAWA TADAAKI
IPC: G02B7/28
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a camera capable of AF control by automatically correcting the aberration characteristic intrinsic to each manual lens in the case of a back focus control system. SOLUTION: The mean value of the correction values of all the lenses which can be mounted is stored in a memory circuit 17. A microcomputer 8 calculates defocusing amount based on data from an AF optical system and sets a value obtained by adding the correction value in the memory circuit 17 to the calculated result as the defocusing amount after correction. In the case variation is inputted by a correction value changing means 9, the correction value is changed. Then, the correction value is shifted in accordance with the color temperature of photographing light by a color temperature measuring means 10. By controlling an AF control system so that the position of a film surface may be moved by the defocusing amount after the correction, the film surface is brought to an accurate focusing position where the aberration characteristic of the lens is corrected.

Title: Sheet material carrier device
Inventor: SASAI KEIZO
IPC: G03G15/00
Filed: 1990-03-15
Abstract: PURPOSE:To make uniform the carrying rate of a sheet material in a widthwise direction, and prevent the occurrence of the wrinkle and jam of the sheet material by setting a friction factor in such a way as to be smaller at ends than at a center for a feed member laid in a widthwise direction for carrying the sheet material with a frictional force. CONSTITUTION:Drive rollers 8a to 8e for carrying a sheet material 3 with a frictional force are so provided as to have a relationship of respective friction factors as mua < mub < muc < mud < mue. Pinch rollers 8a to 8e are so arranged as to oppose the aforesaid drive rollers 8a to 8e, thereby causing a pressing force to act on both ends of a shaft 9f. As a result, a shifting force is generated and the pressing contact forces of respective opposite rollers come to have a relationship of Pa > Pb > Pc > Pd > Pe. Consequently, the rollers have no approximately equal carrying force F for the sheet material 3 (= mu . F) between each position. According to the aforesaid construction, a carrying rate proportional to the carrying force becomes constant in the widthwise direction of the sheet material 3 and, therefore, both ends of the sheet material 3 do not tend to move toward the center, thereby enabling the effective prevention of wrinkling, waving and jamming.

Title: Piping penetration part for fuel cell pressure vessel
Inventor: MURATA NOBUTOSHI
IPC: H01M8/24
Filed: 1995-03-24
Abstract: PURPOSE: To suppress the temperature reduction in passing gas owing to heat radiation from a piping penetration part in a pressure vessel without depending on a heat source so as to accomplish the simplification of equipment and the reduction in operating costs. CONSTITUTION: When a double tube through part 20, in which a fuel gas pipe 13 is passed through, is used, in an oxidation gas pipe 15 provided with a pipe diameter 3-5 times as large as that of the gas pipe 13, a flow rate is greatly increased. Therefore, the temperature of oxidation gas inside the gag pipe 15 is not reduced in heating of fuel gas inside the gas pipe 13. On the other hand, the temperature of the fuel gas becomes the same temperature as the oxidation gas because of heating from the oxidation gas.  The oxidation gas is used as supply gas temperature to a layer built cell 11 following a cell reaction, and at last, discharged from an oxidation exhaust gas pipe 16 as oxidation exhaust gas, however, a part of the oxidation exhaust gas is recirculated so as to be used as oxidation gas, so that temperature regulation cas be carried out, and the oxidation gas and the fuel gas can be fed to the cell 11 at a planned temperature by increasing the supplying temperature by the temperature reduction amount.

Title: Plasma processor
Inventor: MAKINO AKITAKA
IPC: H01L21/3065
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To suppress the bonding of foreign matters onto a vacuum container especially onto the contact part with plasma, thereby decreasing the production of the foreign matters by providing a sustaining means for the plasma producer in the vacuum container at the temperature exceeding the heating temperature of a specimen. SOLUTION: A specimen 7 as a object to be treated with its treatment surface turned upward is mounted on a specimen base 6, so that a plasma producer is arranged above the specimen 7. Accordingly, foreign matters produced in the plasma producer fall down by gravity to be bonded onto the specimen 7. In such a constitution, the bonded items re-dissociated by plasma to be bonded onto the inner wall of a vacuum container 5 are produced in a plasma producer bordered on a grid 10, so that a heater 11 may be arranged on the plasma generator side of the vacuum container 5 to be heated sustained at the temperature exceeding the treatment temperature of the specimen 7 for avoiding the redissociation. Through these procedures, the bonded item amount onto the plasma producer of the vacuum container 5 can be reduced, thereby enabling the foreign matter production to be decreased.
