Abstract: A light-emitting device includes a substrate including a top surface, a first side surface and a second side surface, wherein the first side surface and the second side surface of the substrate are respectively connected to two opposite sides of the top surface of the substrate; a semiconductor stack formed on the top surface of the substrate, the semiconductor stack including a first semiconductor layer, a second semiconductor layer, and an active layer formed between the first semiconductor layer and the second semiconductor layer; a first electrode pad formed adjacent to a first edge of the light-emitting device; and a second electrode pad formed adjacent to a second edge of the light-emitting device, wherein in a top view of the light-emitting device, the first edge and the second edge are formed on different sides or opposite sides of the light-emitting device, the first semiconductor layer adjacent to the first edge includes a first sidewall directly connected to the first side surface of the substrate,

Abstract: A multi-socket computer adapter having a trapezoidal shell, a plug alternatively mounted in different orientations on the trapezoidal shell between two reversed directions by removal and reassembly for connection to a power output socket of a computer to receive power supply from the computer, and a plurality of sockets integral with the trapezoidal shell and connected in series to the lug for receiving computer peripheral apparatus, whereby when the computer is turned off peripheral apparatus joined to the adapter lose power.

Abstract: An improved electrical connector for computers adapted for connecting electric currents to cooling fans of CPUs or computer peripheral equipment. The electrical connector includes a front housing and a rear housing joined together integrally and a plurality of contacts each comprised of a front portion and a rear portion fitted respectively to the ends of a connection portion, the contact being placed inside the front and rear housings. The contacts are firmly held within the housing due to the configuration of the inner walls of the front and rear housings. The assembly process is simplified and costs reduced. The overall reduced size of the electrical connector occupies makes efficient use of the limited space of the computer.

Abstract: A multi-outlet electrical adapter having a plug unit at one side adapted for connecting to a power outlet socket of a computer mainframe, an electrical outlet adapted for receiving an electrical plug of an electrical cable of a computer peripheral equipment, and one receptacle unit disposed at a second side, the receptacle unit and the receptacle unit being so designed that a plurality of multi-outlet electrical adapters can be connected together by connecting the plug unit of one multi-outlet electrical adapter to the receptacle unit of another.
