Title: Refrigerator
Inventor: NAEMURA YOSHIRO
IPC: F25D23/00
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To enhance the evaporation efficiency of defrost water by rotating a fan at an increased r.p.m. until an evaporation accelerating time elapses after ending defrost operation through a defrost heater. SOLUTION: A decision is made whether a defrost operation is ended (Sa1) and if it is ended, a fan is rotated at an increased r.p.m. and counting of the evaporating time rotating at the increased r.p.m., i.e., the integrated rotation time T of the fan, is started (Sa2). When the integrated rotation time T of the fan reaches a specified time T1 (e.g. 1 hour) (Sa3), r.p.m. of the fan is returned from the increased r.p.m. back to the normal r.p.m. (Sa4). When the r.p.m. of the fan increases, evaporation of defrost water stored in an evaporation pan is accelerated temporarily but it is decelerated when a specified r.p.m. is exceeded. It is because the water temperature decreases as the flow rate increases although evaporation is accelerated. The fan is rotated at a balanced point, normally at 2,000 r.p.m.

Abstract: PURPOSE:To form a penetration diffusion layer which is faultless and has a good pattern size, by a method wherein an aluminum predeposition layer is formed on a surface, an alloy containing surplus aluminum is removed, and punch-through  diffusion is performed together with dopant in the other p-n junction. CONSTITUTION:An aluminum 11 is deposited on the both surfaces of a silicon substrate 10 in the pattern of a penetration diffusion layer and heat-treated to form an aluminum predeposition layer (a silicon recrystalizing layer containing an aluminum diffusion layer and aluminum) 12 and an alloy layer 13 whose main body is aluminum. Next, the alloy layer 13 is removed using aqua regia by etching so that in punch-through diffusion, crosswise diffusion cannot develop  more than needed. In addition, to form the base layer and emitter layer, boron  predeposition layers 14, 15 are formed using a silicon oxide film 16 as a mask  and boron nitride. Then a penetration diffusion layer 17 is formed by punch- through diffusion of boron and aluminum simultaneously, thereafter an n type  emitter layer 20 is formed by selective diffusion of phosphor.

Filed: 1993-06-16
Abstract: PURPOSE:To restrain a sheet-type dry-etching equipment from fluctuating in etching characteristics in an early etching stage by a method wherein the etching equipment is set in etching conditions corresponding to the etching sequence of wafers. CONSTITUTION:A dry etching equipment is capable of etching a wafer under a condition A at the same etching rate as a condition B in an early etching stage. A first wafer is etched under a condition A lessened in power in an early etching stage wherein an etching rate is high, and a second wafer and subsequent wafers are etched under a condition B in a subsequent etching stage wherein an etching rate becomes stable. Or, a first, a second, and a third wafer are etched under conditions A, B, and C gradually lessened in power respectively so as to restrain wafers from varying in dimensions. By this setup, an etching rate uniformity can be improved from 16% to 7%, and a dimension uniformity can be improved from 9% to 4%.

Abstract: PURPOSE:To enhance pressure resistance and heat transfer performance of a heat transfer pipe, reduce draft resistance and facilitate working of the pipe by joining a passage member to a pipeline so that an opening part is closed by a peripheral wall of the pipeline. CONSTITUTION:A heat transfer pipe 4 comprises a small diameter pipe 41 and passage members 42 each of which has a longitudinally extending opening part at a part of a peripheral wall thereof, and are arranged in parallel so that the opening part of each of the passage members 42 is opposed to the peripheral wall of the adjacent passage member 42. A solder or brazing filler metal foil 6 is clamped between adjacent ones of the pipe 41 and the passage members 42. Soldering or brazing is conducted by pressing in the direction of an arrow C to bring the small diameter pipe 41, the foils 6 and the passage members 42 into close contact with each other, thereby obtaining the heat transfer pipe 4 comprising a plurality of split passages 4a, 4b, 4c and 4d. Each of the passages similar in shape to a small diameter pipe with a circular cross section, whereby pressure resistance performance is enhanced. The heat transfer pipe thus obtained is superior in heat transfer properties, and can be reduced in draft resistance, as compared with conventional heat transfer pipes.

Combustion air flowing into the cylinder 15 through air injection ports 14 in the lower part of a middle flame cylinder 13 goes up along the inside wall of the cylinder 15, and mixture of the air with the evaporated fuel is promoted because fins 18 projected to the inside are spirally provided on the wall of the cylinder 15 above the through-holes 17 for combustion exhaust gas which are provided on the side wall in the lower part of the cylinder 15, and flames are formed on the air injection ports 14 in the upper part of the flame cylinder 13. A structure is such that it is necessary for a mixed gas to take as time to reach the air injection ports 14 in the upper part of a flame cylinder 13 where flames are to be formed. Accordingly soot and CO will not be produced in the flames formed on the air injection ports 14, besides combustion noise can be reduced because combustion is stabilized.
