摘要： A mold for compression molding a resin article, which mold consists of male and female molds, wherein, at the time of complete mold closing, the length L in a mold closing direction of a mated part formed between the outermost wall of said male mold and the innermost wall of said female mold satisfies the equation: (t1−t0+10)mm≧L≧(t1−t0)mm wherein t1 is a distance (mm) between the male and female molds when the resin melt first reaches the mating outermost edge of the male mold, and t0 is a distance (mm) in the mold closing direction between the same points on the male and female molds as those used for measuring t1 when the mold closing is complete, and the horizontal distance of a mating gap between the outermost wall surface of said male mold and the innermost wall surface of said female mold is from 0.02 to 0.1 mm, with which mold, squeeze-out of a resin melt during molding is prevented.

摘要： A liquid container includes a drop dispensing tip with a hollow stem which defines a liquid passageway and an interior partition wall in the passageway. The partition wall separates the liquid passageway into an upstream chamber and a downstream chamber. Flow communication between these two chambers is provided by a liquid passage in the partition wall. The liquid passage guides liquid against an impingement surface in the downstream chamber from which the liquid is dispensed dropwise.

摘要： A mold vent and method. The vent has expanding passages. A preferred vent comprises an insert that has a plurality of passages. One insert comprises a grate formed of a plurality of portions that interleave fingers forming vent passages therebetween that preferably are vent slots. Supports can be disposed between fingers. The grate preferably is discharge-machined from a blank cut from stock made material that preferably is non-porous and smooth. The grate can be mounted in a pocket in the mold cavity or carried by a movable pin. The grate can be used in a system that includes valving, a source of fluid, and, if needed, a source of vacuum to help facilitate venting by drawing atmosphere out of the cavity during molding. The grate can also be used to introduce fluid into the mold that can be foaming moldable material or a heat transfer medium.

摘要： The present invention provides an injection molding method for providing a molded product with excellent transcription and an excellent gloss level. In this method, immediately after a resin is filled in a cavity (1), a carbon dioxide gas is injected or the skin layer is moved back to form a space (13) between the resin and the die surface (1), so that growth of the skin layer is hold down, and at the same time the carbon dioxide is dissolved in the skin layer for lowering the glass transition point of skin layer. Then the skin layer is again closely cohered to a surface of the die by increasing the resin pressure and cooling the molded product for solidifying behind the holding pressure. With this method, products with excellent transcription and with an excellent surface gloss level can be obtained.

摘要： The cassette half molding method molds one of upper and lower halves of the magnetic tape cassette by injection molding with an injection mold in which a gas vent pin for smoothing a flow of molten resin to be introduced in the cavity for molding a transparent or semitransparent window portion provided in the upper half. The cassette half is molded by this molding method. The magnetic tape cassette has a friction sheet interposed either between a pair of take-up hubs and the upper half, or between the pair of take-up hubs and the lower half, or both, and the friction sheet is made of polyethylene-based resin and has a surface electric resistance value in the range of 1×107&OHgr; to 1×1010&OHgr;. The magnetic tape cassette has a rib for reducing a resistance when the roller of the detecting member passes through which is provided at a position corresponding to a recess and on a side of the front lid in the top surface of the body case.
