In an injection mold, a compression pin is placed at a cavity surface by the pressing force of a biasing member, and is moved rearward by the pressure of filled resin so as to form a compression boss. After the completion of filling, the compression boss is compressed by the compression pin.

The invention relates to a magnetic bearing stator component and a preparation method thereof. The stator component comprises a stator iron core (2), coils (3) and two stator iron core frameworks (1), wherein the two stator iron core frameworks (1) are respectively buckled to two axial end parts of the stator iron core (2), wherein one buckled end of one stator iron core framework (1) is provided with a hollow part (18), and the buckled end of the other stator iron core framework (1) is provided with a projection part (19); the hollow part (18) and the projection part (19) are buckled with each other; each coil (3) winds the corresponding tooth (22) of the stator iron core (2). The stator component is easy to assemble; after installation, the two stator iron core frameworks can be fit completely, the assembling is firm, and the insulation reliability can be ensured; moreover, the completely same structure can be adopted for the two stator iron core frameworks, the part universality is relatively high, and parts can be changed mutually in the assembling process; meanwhile, the mold opening expense also can be reduced, and the standardization can be realized easily.

A casing of an electronic key transmitting and receiving apparatus is formed to seal entire bodies of circuit parts, a mounting face of a printed board, on which the circuit parts are mounted, and parts of terminals while the other parts of the terminals are exposed. A rear face of the printed board opposite from the mounting face provides a part of an outer surface of the casing. When the printed board is provided in the casing through an insert molding process, the printed board is held in a cavity of a molding die such that the rear face of the printed board closely contacts an inner face of the cavity. Accordingly, deformation of the printed board due to pressure caused when the resin is poured or when the resin hardens is inhibited.

A bobbin module of transformer is provided. The bobbin module includes two bobbins. Each of the bobbins comprises a body, an indentation and a hooker. The body has a lateral surface on which the indentation and the hooker are disposed. The hooker and the indentation of the bobbin are respectively engaged with the hooker and the indentation of the other bobbin so that the two bobbins are combined together.

A locking handle for fixing a motherboard of a framework includes a locking part, a shell, an elastic part, and a fixing part. The locking part has an extending portion. The extending portion is projecting from the other side of the main portion. The extending portion has a stopping portion. The shell has an accommodating space inside. The shell is assembled with the extending portion slidingly. A hook and A hole are formed at a side of the shell. The hole is through the accommodating space. A grip is integrally formed at an end of the shell. The elastic part is disposed in the accommodating space. The elastic part is compressed between the fixing part and the stopping portion. The operation is easier. Moreover, the cost of manufacturing is saved.

A water stopper for sink that is used in a water stopper base includes a water stopper body, a fixed rod, a plug and a pulling head. The plug is a rubber block having a through opening in the central portion thereof, and a trough is upwardly formed from the bottom surface of the plug. With the trough, the plug is able to sustain pressure from every side due to its resilient reformation. A circular protrusion is formed at an enlarged periphery of the plug, so that the lower portion of circular protrusion forms a guiding section, the rear end of which is tapered toward the trough to form a curved bottom edge.
