Abstract: An automatic system for processing and testing gears has a processing machine, a testing machine, and a robotic arm. The processing machine has a controller and a gear exchanging platform. The testing machine is connected to the processing machine via wired or wireless signals, and has a calculator and a testing platform. The calculator is connected to the controller via the wired or wireless signals, and the testing platform is electrically connected to the calculator. The robotic arm connects the processing machine and the testing machine, and has at least one claw that is able to move gears from the gear exchanging platform to the testing platform.

Abstract: An optical energy driven information display device comprises an information-display unit, an optical-to-electrical energy converter, and an electricity-control unit. Wherein the information-display unit includes a memory unit, a display unit, a display-control unit, and an information transmission control unit. The information transmission control unit transmits information to the memory unit, and the display control unit. The display-control unit electrically connects the display unit and the memory unit for displaying information in the display unit. The optical-to-electrical energy converter transforms light energy into electricity, and transmits the electric energy to the electricity-control unit, providing power to the information-display unit for displaying information.

Abstract: A foldable collection box includes a foldable outer box and a drawer-style storage box for facilitating folding and collecting and having a smallest size, thereby having a convenience in using. The outer box and the drawer-style storage box are made by sewing a soft material, and delectable supporting boards and fixed supporting boards are sewed inside the outer box and the drawer-style storage box, respectively. In addition, movable supporting boards are located inside the boxes to enhance strength of the entire box structure, and an opening is located at a proper position at a rear wall of the outer box for avoiding a generation of vacuum inside the outer box, thereby facilitating drawing out and emplacing in the drawer-style storage box.

Abstract: A folding frame structure, wherein a folding structure includes two movable binded members and a fixing clasp member. Two ends of the two movable binded members are respectively affixed to edges of a fixed supporting board and a movable supporting board, and two fastening members are respectively affixed to movable ends of two of the movable supporting boards. After joining together the two fastening members by a mutually embedding method, a fastening catch then securely clasps together the two fastening members. The present invention not only increases convenience when assembling the case, moreover, it effectively reduces the dimensions of the case after folding to facilitate storing away.

Abstract: A case with a collapsible frame. The collapsible frame has four straight walls and four connectors. Any two continuous straight walls are connected to each other by means of a connector. Each connector has a link assembly and a buckle assembly which consists of a female buckle and a male buckle. A straight wall is linked to the link assembly which is further linked to the male buckle which is engaged with the female buckle which is linked to another straight wall. The link assembly has several links. Any two continuous links have a first relative position so that they are allowed to pivot relative to each other and a second position so that they are kept from pivoting with respect to each other. The frame is collapsible when the links are in the first relative position and the female buckle is disengaged from the male buckle. The case occupies small space when the frame is folded. A frame is formed when the links are in the second relative position and the female buckle is engaged with the male buckle.
