The molding stock material consisting of such metal powder is heated for 15-60min at 800-1,200 deg.C in a vacuum or gaseous hydrogen atmosphere and is thereby sintered. The electron beam is then projected on the surface of the sintered part in a vacuum to seal the fine pores on the surface of the sintered part; thereafter, the sintered part is subjected to the hot isostatic treatment. The high-density high-alloy sintered parts are thus produced by the simple state at a low cost.

The total extending length of the wire 6 after the specified time is determined and the apparent descending speed A is determined by taking the measurement time into consideration. The determination of the actual descending speed B is executed by first seating the weight 7 on the raw material layer 4, then immediately pulling up the weight 7 and again setting the weight 7 on the raw material layer 4 after the specified time. The descending amt. is determined from the difference in the length of the wire 6 and the actually descending speed B is determined by taking the measurement time into consideration. The avalanche condition of the raw material layer 4 is detected from the A and B determined in such a manner.

Filed: 1990-03-29
Abstract: PURPOSE:To reduce the cost and weight by providing a recessed part on the side of a fixed shaft and a projection part on the side of a motor housing so that they engage each other. CONSTITUTION:The recessed part 17a which is coaxial with the external diameter of a bearing surface is formed in the fixed shaft 17 at the lower end part, the motor housing 21 is bottomed, and the cylindrical projection part 21a is projected integrally in the center of the bottom part.

The coefficient of linear expansion of the motor housing side is made larger than that of the fixed shaft side and when the temperature rises during the rotation of the polygon scanner, the projection part of the motor housing expands relatively more than the recessed part of the fixed shaft to fix the fixed shaft strongly to the motor housing. Consequently, a pedestal can be eliminated and the cost and weight are reducible.

Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To discharge pressure release gas outside smoothly, by forming a pressure release duct, putting the horizontal length and the vertical height of an incline and the bore in vertical direction in specified relation. SOLUTION: In a passage made inside a pressure release duct 4, the outer wall face in the middle bent at a right angle is made at an incline 4a which crosses, at a right angle, a vertical passing a ductcore, and besides has a specified angle to the horizontal. Then, the horizontal length L and the vertical height H of the incline 4a have dimensions four-tenths as large as the vertical inside diameter D of the straight part on the side of a gas charge container 1 of a pressure release duct 4. That is, it is made in the relation of L, H>=0.4D. In the pressure release duct 4 in such form, a pressure release gas flow, which flows reversely, being reflected on the inwall of the pressure release duct 4, does not exist, and the pressure release gas flow becomes smooth. Therefore, the cost rise can be suppressed without raising the strength of the gas charge container 1 more than necessary.
