Abstract: An injection molding apparatus includes a first mold, a first mold module, and a cover plate. The first mold includes a first receiving groove. The first mold module is disposed in the first receiving groove. The first mold module includes an upper surface, a lower surface, an injection groove formed on the lower surface, a central channel formed on the upper surface, and cooling channels formed on the upper surface. The central channel and the first ends of the cooling channels are above the injection groove. The cover plate covers the upper surface, the central channel, and the cooling channels. The injection groove, the central channel, and the cooling channels are separated from each other, and the cooling channels are arranged radially on the upper surface and surround the central channel.

Abstract: An injection molding apparatus includes a first mold module, a second mold module, and an ejection mechanism. The second mold module is disposed on the first mold module. An injection chamber and a product chamber are formed between the first mold module and the second mold module. The ejection mechanism includes a main ejection assembly; a main ejection rod mounted to the main ejection assembly and passes through the first mold module; the central ejection assembly disposed in the main ejection assembly; and a central ejection rod mounted to the central ejection assembly and passes through the first mold module. After plastic in the injection chamber and the product chamber are cooled, a plastic product and an injection part connected to the plastic product are formed. Next, the central ejection assembly is lifted to separate the injection part from the plastic product by the central ejection rod.

Abstract: The easy-to-use tea bag is tubular and pliable, easily fits into a standard small mouth bottle and has two ends, a tubular body, two closures and an inner cavity. The tubular body is formed between the ends. The closures are formed respectively at the ends, and each closure has a strength part. The inner cavity is formed between the two ends and holds tealeaves or other material for steeping. The easy-to-use tea bag being tubular and pliable makes inserting and removing the easy-to-use tea bag into and from a bottle easy.

Abstract: A pair of glasses include a rim having two opposite sides each formed with a receiving hole having a periphery formed with an urging face directed outward in an oblique manner, and a protective module selectively mounted on the rim and including a protective frame mounted on an inner side of the rim and having two opposite sides each formed with a snapping portion forced into the receiving hole of the rim and urged on the urging face of the receiving hole of the rim, so that the protective frame is secured on the rim. Thus, the protective module is combined with the rim rigidly and stably so that the glasses can provide a protective function to the user.

Abstract: An apparatus and a method for trapping a toxic gas contained in an exhaust gas from a process chamber are disclosed. In the apparatus, two toxic gas traps are provided which are connected in series with a toxic gas sensor provided thereinbetween and in fluid communication with the two traps. When toxic gas is detected by the toxic gas sensor, i.e., an indication that the first toxic gas trap is fully consumed, the second toxic gas trap is used to replace the first toxic gas trap, while a new toxic gas trap is installed as the second toxic gas trap. The present invention novel apparatus and method enables the full use or utilization of a toxic gas trap and results in significant cost savings. Furthermore, the present invention novel apparatus and method improves the yield of a fabrication process by reducing the machine down time since the service frequency for the chamber is reduced.
