The upper includes a foot conforming support member, an inflatable exoskeleton and an overlay which inhibits outward bulging of the exoskeleton. The sole includes a rigid carrier element, a forefoot unit and a heel unit. The forefoot unit includes a plurality of components which are arranged to work with the biomechanics of the foot. The athletic shoe is structurally minimalistic and functionally efficient.

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.

A molding apparatus of a glass material according to the present invention is characterized by containing means for holding a glass material and a molding die in contact with each other, means for heating the glass material and the molding die, and means for applying a voltage across the glass material and the molding die, in which press-molding is performed by electrostatic attraction acting between a surface of the glass material and a surface of the molding die. Further, a molded product of a glass material according to the present invention is characterized by including an alkali metal as a component, in which a concentration of the alkali metal is lowered in vicinity of a surface to be molded as compared with that of a glass base material.

An article of footwear includes a frame having a plurality of elongate members formed of a first polymer. A plurality of links is formed of a second polymer, with a portion of each link co-molded about a portion of at least one elongate member, and at least one link movable with respect to a corresponding elongate member.

The present invention is to reduce the package cost and secure the high reliability in an optical module having an optical device and an optical fiber. In the case where the optical module is constituted by use of a pre-molded plastic package, a molding resin is flown parallely with the optical axis direction of the optical fiber on which the plastic package is formed by injection molding. Further, in the case where the plastic package is formed by the comprehensive molding, the flowing direction of resin is parallel with the optical axis direction of the optical fiber to be installed. In the case where a resin case is used, the package exhibits the high rigidity and low thermal expansion properties in connection with the flowing direction of resin, thus reducing the external stress and thermal stress applied to the optical fiber. Accordingly, the high reliability is secured. In the case of the comprehensive molding, the molding pressure applied to the optical fiber is reduced. Therefore, the high reliability is secured.

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.

An electric one-bag golf cart that carries a single caddie bag for a player on a golf course is provided. The cart body, including a chassis part, a neck part and a steering device part, is formed as an integral hollow piece using the rotational molding method. The wheel system provided under the chassis consists of one front wheel and two rear wheels, with the front wheel being mounted pivotally on a suspension as a free wheel, while the rear wheels are driving wheels using a differential gear device driven by a motor. At the center of the handlebars, which are made of circular rods, a dial-type speed controller is located, and a brake lever is provided under the steering device, together with a lock mechanism.

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.
