Abstract: PURPOSE:To enable the easy and sure press welding of metallic materials having large difference in hardness and ductility in a press welding method for two metallic materials by heating the fayed surfaces of the metallic materials to soften prior to the press welding. CONSTITUTION:In the case of press welding, for example. ''Toughpitch Copper '' 10 having high hardness and Al 11 having low hardness, the material 10 is subjected to a pretreatment of making the hardness thereof approximate to the hardness of the material 11 by heating said material locally or wholly in a heating furnace 12 or the like. Thereafter, the materials 10, 11 are clamped in jigs 2 and are thereby restrained. The jigs 2 are adjusted to provide a suitable projecting length to the materials 10, 11, which length is used as a margin 3 for press welding. The materils 10, 11 are then pressurized with hydraulic mechanisms or the like so as to be applied with plastic deformation, whereby the flow metal is extruded toward the outside circumferences of the materials 10, 11 and the joint of fayed surfaces 4 is obtained. Since the difference in the hardness between the materials 10 and 11 is decreased, the plastic deformation is effected smoothly, the flow metal is flowed easily toward the outside circumferences and the press welding is accomplished easily and surely.

IPC: B60T8/52
Filed: 1993-02-12
Abstract: PURPOSE:To smoothen variation of brake pressure by providing a damper means to resist movement of working oil accompanying expansion/contraction of an oil chamber. CONSTITUTION:A regulator 12 is provided with a cylinder 26 and a torque detecting rod 28 slidably projecting from the cylinder 26. An oil chamber 33 is defined by a feedback piston 8 inside the cylinder 26, and the oil chamber 33 is communicated to a hydraulic circuit 6 through an orifice 34. Because the orifice 34 gives resistance to flow of working oil between the oil chamber 33 and the working oil passage 6, it functions as a damper to resist sudden expansion or contraction of the oil chamber 33. As a result of this, motion of the feedback piston 8 is smoothened, generation of resonance phenomenon is prevented, and hence pressure of the working oil passage 6 is smoothly changed according to variation of brake torque.

Title: Etching system
Inventor: TOYODA MASATO
IPC: C23F4/00
Filed: 1992-02-12
Abstract: PURPOSE:To uniform the plasma distribution on the surface of a wafer and suppress the production of plasma on the inner wall of a reaction chamber by enlarging the diameter of a microwave introduction window than that of the semiconductor wafer and enlarging the diameter of the reaction chamber than that of the microwave introduction window. CONSTITUTION:In case the density distribution of a semiconductor wafer 7 is uniform within the range of the diameter of a microwave introduction window 12, and the diameter of the wafer 7 is smaller than that of the microwave introduction window 12, ECR plasma provides the surface of the wafer 7 with a highly uniform etching result. Microwaves introduced into a reaction chamber 13 through the microwave introduction window 12, is weak out of the range of the diameter of the window. If the diameter of a reaction chamber 13 is larger than that of the microwave introduction window 12, therefore, the production of plasma is suppressed in proximity to the inner wall of the reaction chamber 13. This uniforms the distribution of plasma on the surface of wafers to offer a uniform etching effect. It also suppresses the production of plasma on the inner wall of a reaction chamber to prevent the harmful influence of reaction products.
