Title: Reaction air supply method of fuel cell
Inventor: TAJIMA HIROYUKI
IPC: H01M8/04
Filed: 1987-09-10
Abstract: PURPOSE:To heat the reaction air to high temperature near the operating temperature and to make the temperature distribution of a cell stack uniform by supplying reaction air to a fuel cell from a starting-use burner heat exchanger as exhaust heat air when a cell stack is cooled and as exhaust heat burning gas when the cell stack is heated, for example, for low output operation. CONSTITUTION:A reaction air supply passage 30 which connects an exhaust pipe 25 of a starting-use burner heat exchanger 16 to an oxidizing agent gas chamber 6 through a stop valve 25 is installed. An exhaust pipe 31 which is branched from the reaction air supply pipe 30 and exhausts excess reaction air to the outside through a stop valve 28 is installed. Air which removed the heat from the cooling water in a heat exchanger tube 18 is changed to high temperature exhaust heat air, and supplied through the stop valve 25 as the reaction air. Excess exhaust heat air is exhausted to the outside by controlling the opening of the stop valve 28. When the temperature of a cell stack 1 is decreased, exhaust heat burning gas from the heat exchanger 16 is supplied through the stop valve 27 as reaction air.

Title: Semiconductor device
Inventor: OMORI EIJI
IPC: H01L23/12
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To enable positional alignment which is more accurate, as compared with the positional alignment of a suction nozzle with a semiconductor device which uses a conventional mechanical method of indirect means, such as a guide and notch installed on a part except a semiconductor device. SOLUTION: This semiconductor device has a radiating plate, whose surface is flat, and a high infrared absorbing resin layer 5A which is black or the like in color is formed on the flat surface of the radiating plate. A target pattern, which has a resin part area of at least 40% of the radiating plate area and is detected by optical image recognition, is formed to the semiconductor device. The target pattern is formed directly to the semiconductor device, and position detection precision of optical image recognition is high, so that positional alignment accuracy of a suction nozzle with the semiconductor device can be improved.  By imparting asymmetry to the target pattern, the direction of the semiconductor device can be recognized, so that errors of the printing direction and mismatch in the directions of the socket of a tester and of the semiconductor device can be prevented, which adds convenience.

Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To provide a lead-acid battery manufacturing method which makes welding possible with a small amount of heat using a method for welding the ears of a plate array for the lead-acid battery to a rack, shortens cooling time, and enhances productivity. SOLUTION: Only a rack 6 that is in contact with the plate ears 5 of a plate array 1 consisting of pluralities of positive 2 and negative 3 plates and separators 4 is partially heated and melted. The rack 6 is thereby welded to the plate ears 5. The rack 6 is preferably made from a lead-tin alloy. The heating method is preferably a high-frequency induction heating method. The welding process is therefore made possible with a small amount of heat required for heating and in a short time, and cooling time after the welding can also be reduced appreciably. The temperatures of the ears 5 can be controlled individually and uniformly by adjustment of the shape, etc., of a heating element, and because of partial melting the rack 6 can be made thinner after welding than in conventional cases. Thinning of the rack 6 allows increase in the height of the plate array 1, with the result that a large capacity ratio can be achieved.
