The retaining member has two abutments with a pair of first grooves defined in the bottom surfaces thereof for the shafts riding therein. First ladderlike rims are formed along edges of the retaining member. The cover has two shoulders with a pair of second grooves defined in the top surfaces thereof. Second ladderlike rims are formed along edges of the cover. The first ladderlike rims engage with the second ladderlike rims to secure the cover on the retaining member, and the first grooves and the second grooves are aligned to define shaft holes for the shafts rotating therein.

Abstract: The present invention provides an accessorial ejecting mechanism mounted beneath a male mold section. The accessorial ejecting mechanism includes an accessorial plate, a rail, a slider, and a movable board. The accessorial plate secured to the male mold section has a recess in the top surface thereof. The rail is received in the recess and fixed to the accessorial plate. The slider, connecting a driving device, is slidable along the rail. The slider defines at least a guiding groove whose opposite ends are in different height. The movable board is also received in the recess. At least a guiding post is fixed to a side of the movable board and extends outwardly into the guiding groove. Sliding of the slider makes the movable board move up and down. Pin cores for forming pinholes of a molded article are fixed to the movable board so as to move up and down together with the movable board.

Abstract: A Mold assembly for forming a plastic article includes a fixed plate, a female mold, a male mold, a first sliding mechanism, a second sliding mechanism, a following block, a threaded pole, and a shaft. The male mold defines a slot. The first sliding mechanism includes a first slider received in the slot and a first inclined pin secured to the fixed plate. The second sliding mechanism includes a second slider received in the slot and a second inclined pin secured to the female mold. A molding cavity is formed in the second slider. The following block for withstanding the second slider is fixed to the female mold. The threaded pole is inserted into the molding cavity for forming an internal thread of the plastic article. An end of the shaft is connected to a driver and the other end is connected to the threaded pole to bring it rotation. While opening the mold assembly, firstly, the first inclined pin pushes the first slider sliding rearward to allow the threaded pole unscrewed.

Abstract: The present invention is a calculator that comprises a body, a couple device and a display unit. The body has several press groups placed on its one side and a display containing space placed on the other side which used for containing the display unit. The display unit comprises a main panel and an assistant panel. The main panel and the assistant panel are placed on two joint planes. The couple device joining the body and the display unit allows the display unit rotate around the couple device Users can make the display unit to stay on open status and closed status by pushing the display unit. The present calculator shows calculating information to users opposite each at the same time.

Abstract: A flashing joystick comprises a power supply which supplying power to the joystick; a key-press group used for users controlling in order to send control signal to game machine to manipulate a game role; a signal transfer device which sending and receiving signal between the joystick and the game machine; a microprocessor which receives control signal from the key-press group and sends it to the game machine by the a signal transfer device so as to manipulate the game scenario progress; at least one LED (Light-Emitting Diode) are joined with the joystick circuit so that emitting flashing light when the circuit electrified; and a joystick shell which is made of penetrating-light material for penetrating flashing light produced by the LED out of the joystick shell. The present invention will emit florid flashing light while the playing course, and the player will get better playing results.

Abstract: A method and apparatus for selectively heating a structure capable of absorbing heat radiations in the 0.5 to 2 micron range relative to an adjacent structure wherein a first structure capable of absorbing heat radiations in the 0.5 to 2 micron range is disposed adjacent a second structure much less capable of absorbing heat radiations in the 0.5 to 2 micron range. An unfocused heat source which provides a major portion of its heat energy in the range of from about 0.5&mgr; to about 2&mgr; relative to heat energy above 2&mgr; and below 0.5 micron directs heat concurrently to the first and second structures to heat the first structure to a temperature sufficiently high and much higher then the second structure to permit a predetermined function to be performed in conjunction with the first structure while maintaining the second structure below a predetermined temperature. The function is then performed. The heat source preferably comprises an unfocused tungsten halogen lamp.
