Title: Vacuum brazing method and vacuum brazing furnace for aluminum
Inventor: HAKOZAKI MASATOSHI
IPC: C22F1/04
Filed: 1986-06-04
Abstract: PURPOSE:To enhance the oxidation preventive reaction of brazed parts and to obtain a product having good brazing quality by covering Al materials to be treated with Mg reflection plates and heating the inside of a vacuum brazing furnace while preventing the splashing of Mg particles when the temp. in the furnace attains the temp. at which the Mg contained in a reducing agent begins to evaporate. CONSTITUTION:The inside 12 of the vacuum brazing furnace is evacuated to a vacuum. The inside 12 of the furnace is heated when the degree of vacuum around the Al materials W to be treated increases. The Mg reflection plates 26 are moved near to the materials W to cover the materials W when the temp. in the furnace increases and attains the temp. at which the above-mentioned Mg begins to evaporate. The inside 12 of the furnace is thereafter heated to the prescribed brazing temp. The splashing of the Mg is thus prevented by the reflection plates 26 in the brazing stage of the materials W and since the Mg is not splashed to the periphery, the contamination in the furnace 12 is prevented. Since the density of the Mg particles around the materials W increases, the oxidation preventive reaction in brazing is enhanced as compared to the conventional product.

IPC: G06K9/46
Filed: 1984-06-25
Abstract: PURPOSE:To increase the picture image processing speed by advancing the end point of an edge toward the maximum evaluation function value obtained about each peripheral point of the end point of a noticed edge. CONSTITUTION:A source selector 6 counts the number of end points and stores the count value to an internal register of an ALU5. Then an access is given to a frame memory 18 by address counters 16 and 17. Thus the first end point ¦E¦, acute angleE and the FLG data can be fetched by the ALU5. Each peripheral point of the end point has at least one edge point (flag=1). Thus this edge point is detected inside the ALU5 and deleted out of the extension candidate points. Then the evaluation function H is calculated between the remaining extension candidate point and a noticed end point. In order to shorten this calculation time, an operation acute angleEo-acute angleEi is performed by the 1st ROM table 11a and the address value of an angle calculation table is written to the 2nd ROM table 11b.
