Abstract: Transistors with improved saturation drain current and methods for making such transistors are disclosed. The gate is formed in the shape of a longitudinal trench and a plurality of lateral trenches below the longitudinal trench. The resulting dual-recess structure increases the surface area of the gate, which permits additional charge carriers and increases the saturation drain current of the transistor. Such transistors can be useful in high voltage and medium voltage applications such as in display driver integrated circuits.

Abstract: An optical path folding element includes a main body, a light absorption film layer and a matte structure. The main body has optical surface including an incident surface, a reflective surface and an emitting surface. A light enters into the optical folding element through the incident surface. The reflective surface reflects the light so as to change a traveling direction thereof. The light exits the optical folding element through the emitting surface. The light absorbing film layer is configured to reduce reflectance and provided adjacent to at least part of the optical surface, and the light absorbing film layer is in physical contact with the main body. The matte structure is disposed adjacent to at least part of the optical surface. The matte structure provides an undulating profile on a surface of the optical path folding element, and the matte structure is formed in one-piece with the main body.

Abstract: A hand tool (100) includes a head section (102) including a top jaw (106) and a bottom jaw (108), a handle section (104) including a top handle (112) and a bottom handle (114), and a joint assembly coupling the head section (102) to the handle section (104). The top jaw (106) is coupled to the bottom handle (114) by a first transition portion, and the bottom jaw (108) is operably coupled to the top handle (112) by a second transition portion. The first and second transition portions are pivotally coupled to each other by a pivot pin (140). The first transition portion is disposed on a first side of a longitudinal centerline of the hand tool (100), and at least a majority of the second transition portion is disposed on a second side of the longitudinal centerline such that a width of the first transition portion is less than a width of the second transition portion.

Abstract: A welding equipment used to form two welding structures in two target locations of an electronic device is disclosed to include a laser generating device for generating a laser pulse beam, a radiation device scanning the two target locations, and an adjusting device equipped with a beam splitting system for receiving and processing the laser pulse beam. The beam splitting system separates the laser pulse beam into a reflected beam and a penetrating beam to control a radiation angle of the reflected beam and the penetrating beam, and project the reflected beam and the penetrating beam to the radiation device coaxially, so that the radiation device radiates the reflected beam and the penetrating beam coaxially to the two target locations to form the two welding structures. The radiation angle is related to relative positions of the two target locations.
