摘要： An injection-compression molding apparatus includes a stationary mold provided with a nozzle for injecting molten resin, and a movable mold driven by a servo motor. In compressing the resin, high-speed position control of the movable mold is first performed, which is then switched to speed feedback control which enables delicate regulation of clamping pressure in accordance with pressure fluctuations in the resin.

摘要： An injection device includes a cylinder, a plunger and a driving device. The cylinder has a port for supplying molding material into the cylinder, and the molding material supplies into the cylinder is compressed by the plunger. The plunger has a groove extending circumferentially around an outer wall of a large-diameter portion of the plunger, and the clearance between the outer wall of the large-diameter portion of the plunger and the inner wall of the cylinder is determined by a specified equation.

摘要： A method of manufacturing the peripheral wall of a tank for an oil-immersed electric apparatus which comprises manufacturing a panel unit through the steps of:fabricating a panel by pressing a thin steel sheet to form an upward extending flange along both edges of the panel and provide a plurality of reinforcement depressions concaved toward the backside of the flat portion of said panel;folding the panel into two parts with the surface of the panel kept outside along the central line extending between both edges of the panel to fabricate a hollow fin;joining both sides of the folded fin by spot welding the reinforcement depressions; andwelding together the closely facing edges of both sides of the fin,and constructing the peripheral wall of the tank by joining together a plurality of panel units fabricated through the above-mentioned steps by welding the flanges of said panel units.
摘要翻译：一种油浸式电气设备用槽的周壁的制造方法，其特征在于，包括以下工序来制造面板单元：通过压制薄钢板来制造面板，以沿面板的两个边缘形成向上延伸的凸缘;以及提供朝向所述面板的平坦部分的背面凹陷的多个加强凹部; 将面板折叠成两部分，其中面板的表面沿着在面板的两个边缘之间延伸的中心线保持在外部，以制造中空的翅片; 通过点焊加固凹陷来连接折叠翅片的两侧; 并且通过将所述面板单元的凸缘焊接在一起，将通过上述步骤制造的多个面板单元接合在一起，从而将翅片的两侧的紧密相对的边缘焊接在一起，并且构成罐的周壁。
