In one embodiment, a PSM comprises a transparent substrate; a phase shift pattern disposed on the transparent substrate; and a passivation layer disposed to substantially cover exposed surfaces of at least a portion of the phase shift pattern.

Abstract: A method of manufacturing irregular shapes of solder wires comprising the steps of: (a) acquiring materials of solder wire; (b) placing the materials into wire manufacturing machines to form solder wires into specifically designed profiles; (c) transporting the resulted solder wires to forming equipment and tools to form solder wires into specific shapes. The invention also provides products made with above-mentioned methods of manufacturing irregular shapes of solder wires.

Abstract: A structure for improving the voltage difference of a connector includes a communication connector, an enclosure, and a conducting gasket. The communication connector is assembled with the enclosure. The conducting gasket is located and conducted at the connection area of the communication connector and the enclosure. Thereby, the conductivity of the communication connector and the enclosure is increased and the voltage difference is improved. Furthermore the connector does not require traditional manual welding for connection; thereby manufacturing time and cost are reduced.

Abstract: An improved mechanism for telecommunication connector including a grounding body, a rear end insulator, a center pin, and other components is provided. The grounding body is a hollow housing with a through hole along its centerline. A center pin is fixed on the center of rear insulator, and the rear insulator with the center pin is installed onto the rear end opening of the through hole of the grounding body. The installed center pin will be on the centerline of the through hole of the grounding body, and a segment of it is exposed outside the assembled connector for connecting with the circuit board or other transmission objects.

Abstract: A method of manufacturing uncommon forms of solder wire without grease or lubricant is provided. The uncommon forms of solder wire is manufactured first by getting a winding rod which can be installed on or removed off the winding machine rapidly, then, obtaining solder wire, and winding the solder wire around the winding rod. Subsequently, fixing the shape as needed and cut the wound solder wire with cutting jigs. Finally, making dotted-line punches for flux to flow out easily, if necessary, and further adjusting the shifted incision gap of each solder wire piece accordingly to the needed shape.

Abstract: A discontinuous capillary coating device. At least one capillary tube is filled with a coating material. At least one coating substrate receives a liquid coating film. At least one capillary tube holder holds the capillary tube, guiding movement of the capillary tube. At least one traversing mechanism drives the capillary tube holder or coating substrate to move.

Abstract: A method for packaging submount adhering LED comprises providing a first substrate which has an upper surface, a lower surface forming a plurality of heat-dissipating cavities and a plurality of die-attaching regions defined on the upper surface. Each of the heat-dissipating cavities corresponds to the die-attaching region and has a bottom surface, wherein there is a carrier base located between the bottom surface and the die-attaching region. Next, a heat conductor is formed in the heat-dissipating cavity and a plurality of LEDs are disposed on the die-attaching regions of the first substrate. Then, a second substrate is provided which has a first surface facing to the upper surface of the first substrate, a second surface opposite to the first surface and a plurality of reflective slots communicating with the first and second surfaces.

In one embodiment, a PSM comprises a transparent substrate; a phase shift pattern disposed on the transparent substrate; and a passivation layer disposed to substantially cover exposed surfaces of at least a portion of the phase shift pattern.

Abstract: A coupling device includes a coupling body, an expandable ring, a washer and a press guide tube. The coupling body includes a substantially cylindrical coupling head and a screw rod; wherein the coupling head consists essentially of an obliquity portion and a receiving portion, a longitudinal slot being provided within the coupling body and passing therethrough, the longitudinal slot communicating with the gas or liquid inside a to-be-detected device or object. The expandable ring and the washer are respectively fitted onto the receiving portion of the coupling body. The expandable ring is provided to enable the coupling body and a circular slot to be coupled tightly. The washer prevents the gas or liquid leakage from the contact surface between the coupling body and the circular slot.
