摘要:
The present invention relates to a method of manufacturing a metal-impregnated body in which a porous body is immersed under sub-atmospheric pressure in a molten alloy for impregnation with said alloy or a porous body is immersed under elevated pressures produced by various gases, the pressure then being reduced to normal level, after which the porous body is introduced together with a molten alloy into a metal mold, in which said molten alloy is impregnated into said porous body. The porous body is then separated from said molten alloy.

The object of the present invention is to provide a production method for an aromatic polycarbonate, in which eye boogers at the time of extrusion molding are reduced, and a continuous operation for a long period of time is possible. The present invention relates to a method when an extrusion molding is produced using an extruder in which a tapered part 1 has a half apex angle of from 4 to 20° formed at the outlet part of a die hole 9, and outlet parts of plural die holes 9 are arranged in a staggered state at the resin discharge surface side of a die plate 10, the shear rate γ at the extruder outlet is from 100 to 500 sec−1, and the shear stress τ is from 50 to 200 kPa.

Lifetime required of mobile-use fuel cells is secured and prolonged, stabilized pump performance is maintained by preventing bearing seizure and abnormal wear. The shaft (101) of a pump mechanism section (100) and the shaft (201) of a motor section (200) are integrated, and the shafts (101, 201) are supported by two or more ball bearings disposed in the pump mechanism section (100), thereby making it possible to fill grease in the closed spaces of the ball bearings (300), and secure a sufficient lifetime basically with almost no possibility of the grease leaking out, even if it is used at a relatively high environmental temperature.

In a method of manufacturing a semiconductor device, a semiconductor substrate having device regions and an isolation region for separating the device region is provided. Then, a trench is formed in the isolation region of the semiconductor substrate. A nitride film is formed on the device regions of the semiconductor substrate. Next, an oxide film is formed within the trench and on the nitride film so that an upper surface of the oxide film within the trench is located more than about 500 Å below an upper surface of the nitride film. Finally, the oxide film is polished by CMP method so that a height of the upper surface of the oxide film within the trench portion is maintained at less than a height of the upper surface of the nitride film adjacent thereto.
摘要:
A method of producing a connecting rod with a bearing, in which both a process for producing a bearing separately from a connecting rod and a process for assembling the bearing to the connecting rod can be eliminated to reduce processes, labor, and costs to produce the connecting rod. A hollow cylindrical molding of a bearing metal material is inserted and fitted, as an inner member, inside an inner surface of a circular large end hole of a large end section of a connecting rod. A tapered surface of a rotary pressing tool is pressed, while rotating, to the hollow cylindrical molding to heat and soften the hollow cylindrical molding, causing the hollow cylindrical molding of the bearing metal material to plastically flow axially and radially outward, whereby a bearing metal layer is directly joined and formed on the inner surface of the large end hole.
