Abstract: A molding process for manufacturing a molded article includes the steps of placing a flexible hollow member in a mold cavity, inserting a supporting member in the hollow member, introducing a molding raw material into the mold cavity around the hollow member to form a molded part that encloses a portion of the hollow member, removing the molded part together with the hollow member and the supporting member from the mold cavity, and withdrawing the hollow member and the supporting member from the molded part to form a channel in the molded part.

Abstract: A pen includes a vertical pen barrel, a mounting seat mounted fixedly on a top end of the pen barrel, and a molded metal unitary unit. The unit includes a pen top disposed swingably on the seat, and a pen clip extending integrally and downwardly from the pen top. The clip has a clamping end, which is movable relative to the pen barrel between a clamping position, where the clamping end presses against the pen barrel, and a releasing position, where the clamping end is spaced apart from the pen barrel. A biasing unit biases the clip to the clamping position.

Abstract: A molding process for manufacturing a molded article includes the steps of placing a flexible tube in a mold cavity, introducing a molding raw material into the mold cavity around the tube to form a molded part that encloses a portion of the tube, removing the molded part together with the tube from the mold cavity, and withdrawing the tube from the molded part to form a channel in the molded part.

Abstract: A method for making a mottled and patterned pen barrel is disclosed, wherein a tube is preformed to have two ends and an intermediate portion, At least one mold cavity is provided in a mold for forming the pen barrel. A pair of positioning members are sleeved respectively around two ends of the tube, and the positioning members are positioned in the mold cavity so as to center the tube in the mold cavity and so as to create, in the mold cavity, a molding space surrounding an entire peripheral surface of the intermediate portion. A liquid coating composition is poured into the molding space to form a cover integral with the entire peripheral surface of the intermediate portion. Finally, the covered tube is removed from the mold cavity and the positioning members are removed from the covered tube.

Abstract: A method for making tubular members, each of which is coated with a decorative layer that has a randomly distributed chip pattern, includes the steps of: (A) preparing tube products, each of which having two ends and an intermediate portion between the two ends; (B) preparing a mold having a plurality of mold cavities; (C) sleeving detachably a pair of positioning members around the two ends of each of the tube products for enclosing and centering the two ends, and placing each of the tube products and the positioning members associated therewith in a respective one of the mold cavities; (D) forming a covering around the intermediate portion of each of the tube products by filling each of the mold cavities with a coating composition containing chips; (E) removing each of the covered tube products and the positioning members associated therewith from the mold, and detaching the positioning members from each of the covered tube products; and (F) machining and polishing the covered tube products, and cutting off

Abstract: A modular panel assembly includes more than one first modular unit having a plate member with a rear face, which has first and second connecting corner pieces longitudinally and oppositely disposed near the side faces. The first connecting corner piece of each of the first modular units is engageable with the second connecting corner piece of another first modular unit. The first modular unit further has a plurality of substantially T-shaped protrusions projecting from a front face of the plate member and forming a plurality of substantially T-shaped grooves between them. Each of the T-shaped protrusions has a pair of oppositely extending flange ends. Each of the T-shaped grooves has a restricted opening between two flange ends. The T-shaped protrusions of each first modular unit can engage with the T-shaped grooves of another first modular unit.

Abstract: A multifunctional sounding and lighting device includes: a housing unit with an upper case and a lower case which are detachably combined to facilitate the operations of the device; a printed circuit board having sound and light circuits disposed therein fixed on the lower case; a buzzer provided in the upper case and electrically connected to the sound circuit for being activated to produce sound thereat; a plurality of light-emitting elements fixed on the PC board and electrically connected to the light circuit for being energized to emit light thereat; a power supply unit provided in the lower case; a pressure switch coupled between the circuits of the PC board and the power supply unit; an actuating member installed in the housing unit for being operated to turn the pressure switch on and off; and a pair of pressure springs disposed between the upper case and the lower case; whereby, when pressure is applied to either side of the housing unit, the actuating member will turn on the pressure switch to perfo

Abstract: A combined display board and clip which comprises a first clamping member, a second clamping member, a mechanism for connecting the first and second clamping members in a pivotal position, a spring for urging the first clamping member to a clamping position with respect to the second clamping member, wherein at least one of the first and second clamping members includes a base plate having opposite edges, a cover plate having opposite edges, and an edge-piece having a groove for releaseably receiving and clamping together the edges of the cover plate and the base plate.
