Abstract:
A telescope imaging system includes a first lens group for receiving a spot light and generating a first refracted beam, a second lens group for receiving the first refracted beam and generating a second refracted beam, a third lens group having a convex lens disposed at a side of the third lens group distant from the spot light for receiving the second refracted beam and generating a parallel beam by an effective focus formed by the first lens group, the second lens group and the third lens group, a first reflective mirror having an opening, receiving the parallel beam and generating a reflected beam, and a second reflective mirror adjacent to the third group lens and reflecting the reflected beam for allowing the reflected beam passing through the opening and focused as an image.
Abstract:
A machining method for a brittle material is provided. The machining method includes steps of heating the brittle material; providing a concentrated cold source; and spurting the concentrated cold source on a surface of the brittle material along a predetermined cutting path.
Abstract:
A backlight structure comprises a frame, a circuit board, and a connector. The frame has an opening. The circuit board is located below the frame and has a through hole, wherein the through hole aligns with the opening. The connector passes through the opening and the through hole, protrudes from a surface of the frame, and is electrically connected to the circuit board.

A photograph device is provided. The photograph device includes a body, a lens device mounted on the body, and an illuminating device mounted on the body and surrounding the lens device.
Abstract:
Locking structure for picture tube and front frame body. Multiple fixing posts are formed on inner side of the front frame body and multiple fixing plates project from outer periphery of the picture tube corresponding to the fixing posts which retain the fixing plates. The front frame body is formed with a central window. When the bottom faces of the respective fixing plates of the picture tube are correspondingly planely rested on the fixing posts of the front frame body, the end edge of the flange of the window of the front frame body is snugly sealedly attached to the periphery of the picture tube. When screws are respectively screwed to forcedly lock the fixing plates of the picture tube on the corresponding fixing posts of the front frame body, the fixing plates are slightly downward inlaid into the top ends of the fixing posts so as to prevent the picture tube from being displaced or slided.

Abstract:
A transfer printing machine for hockey sticks include a base, a transmission unit connected to the lower portion of the base and five stations located on the top of the base. The five stations are located along the transmission direction of the transmission unit. The first station prints patterns on a top surface of a straight handle of the hockey sticks which are moved by the transmission unit. The second station prints patterns on a left side and a right side of the straight handle. The third station and the fourth station print patterns on a first inclined surface and a second inclined surface of the straight handle respectively. The fifth station prints patterns on a bottom surface of the straight handle of the hockey sticks.
Abstract:
