Abstract: In a system for automatically manufacturing a pipe spool, when information on a pipe spool is input to a control unit, manufacturing of a spool pipe by cutting an original pipe, processing of a spool pipe, processing of a connection member, manufacturing of a straight pipe spool by welding a spool pipe to a connection member, and manufacturing a three-dimensional spool by welding a straight pipe spool to the other straight pipe spool or a connection member may be automatically performed by a sensor, an automatic device or a robot included in each process and the control unit connected to each of the devices.

Abstract: A self-contained portable solar power supply system is specifically designed to convert solar energy into electrical energy, and charge a rechargeable storage battery to energize edge-lit lighted panels as back-lighting devices in the dusk to illuminate advertising graphics and messages installed on waste receptacles disposed on the city street curbs. The stored electrical energy is discharged by a dual control of a 24-hour timer unit and a photo light sensor control unit on a daily basis. To conserve the electrical energy consumption, the photo light sensor control unit is super-imposed as a second control over the time schedule of the 24-hour timer unit to ensure that the electrical energy will be discharged only when the photo light sensor control unit detects the light conditions in the immediate area diminish below a predetermined minimum light level setting. The photo light sensor control unit alleviates the need to reset the 24-hour timer unit as the local sunset time changes year-round.

Abstract: An edge-lit lighted panel for bulletin boards comprising a generally planar rectangular panel of light-transmitting material having a top surface and bottom surface surrounded by four edge surfaces, and at least one linear light source imbedded in and sealed along at least one edge surface. The linear light source includes a longitudinal semi-circular reflector to direct the light from the linear light source toward the adjacent edge surface to increase the amount of light entering the edge surface of the planar rectangular light-transmitting panel. The linear light source and the longitudinal semi-circular reflector are installed inside an edge trim housing that is configured to be attached to the edge surface of the planar rectangular light-transmitting panel.

Abstract: The present invention discloses an alignment apparatus, including: a table; a plurality of guide pins positioned on a peripheral protion of the table; a determined area defined by the guide pins in the table; a plurality of lift pins positioned in the table and moving from the table to the height of over the guide pins; a plurality of proximity pins located on the table to hold the substrate when the lift pins are descended; a cylinder positioned under the table aid driving a plurality of movable arms in a transverse direction; and a plurality of alignment pins extended from the movable arms in a longitudinal direction.
