A composite legal type bicycle frame is disclosed which contains a front frame portion and a rear frame portion. The front frame portion contains a central main and a plurality of legs for connecting the central main with various components of the bicycle, and the rear frame portion contains a rear fork, which consists of a left rear branch and a right rear branch. The left and right rear branches are first cured and glued together at respective abutting surfaces thereof to form an integral rear fork before they are adjoined with the front frame portion, via prepregs and using a cocuring procedure. The left and right rear branches are formed to contain cross-shaped matching protrusion and recess, respectively, on the abutting surfaces thereof, so as to enhance the integrity of the integral rear fork. As a result, a great flexibility of design options can be obtained. For example, the rear fork can be connected to one of the legs but not to the central main. Also, the front frame portion can be designed such that one of the legs is connected indirectly to the central main via another leg, and not directly connected to the central main.

A method of molding a composite bicycle frame that includes the steps of curing a pair of seat stays and chain stays respectively and then connecting with the front triangle. Non-foaming dilatable materials are provided at suitable locations in the mold, such as the steering support cavity, the pedal support cavity, the seat stay butting cavity and the chain stay butting cavity. By heating the mold once, the seat stays and chain stays will secure with the front triangle and the front triangle can be cured at the same time to simplify the mold and the process.

An automatic paper feeder including an upper light source comprises of a paper tray for holding a plurality of scanning documents, a base frame for mounting on the scanning platform of a scanner, a channel for guiding the scanning document to move along a desired direction and path, an upper light source, a transmission unit for picking up and moving the scanning document, a control unit for controlling the transmission unit and the upper light source, and a cable for wiring the automatic paper feeder to the scanner. The paper feeder enables the scanner to perform paper-feeding type scanning at high scanning efficiency. Beside providing automatic single page feeding, the automatic paper feeder also able to perform transparency scanning through its upper light source. The scanner equips with this automatic paper feeder thus able to perform dual function of reflective type and transparency scanning.

A paper-loading mechanism for a document duplicating machine, which is driven by a reciprocating part in a document duplicating machine and performs periodical paper-loading control on a paper loader of the document duplicating machine, comprises an actuating unit, a transmitting unit, a paper-feeding pushrod, and a torsion spring. The actuating unit is utilized to provide reciprocating motion for the paper-loading mechanism for a document duplicating machine and is pushed by the reciprocating part along a line parallel and adjacent to one end of the trajectory of the reciprocating part. The transmitting unit is connected with the actuating unit and is used to transfer the reciprocating motion from the actuating unit to the feeding pushrod. The paper-feeding pushrod is located along one side of the paper loader of the document duplicating machine and is rotated along its own longitudinal central axis. The torsion spring is used to restore torsion energy and to drive smoothly the feeding pushrod, with one end thereof connected with the feeding pushrod and another connected with the transmitting unit.
摘要:
A method for making continuous fiber-reinforced plastic composites is disclosed. It involves the steps of (a) using an extruder to continuously extrude a first plastic resin through an extruder die to form a first plastic resin layer; (b) continuously pulling a plurality of prepreg strips along with the first plastic resin layer; and (c) combining the plurality of prepreg strips with the first plastic resin layer to form a sandwiched composite containing at least two prepreg layers separated by the first plastic resin. The prepreg strip contains reinforcing fibers impregnated with a second plastic resin. The fiber-reinforced and sandwich-structured plastic composites exhibit greatly improved flexural strength and flexural modulus approaching those of real wood, and can be drilled, nailed, chiseled, saw, etc, similar to natural wood.
