  • Publication number: 20100166290
    Abstract: A die defect inspecting system with a die defect inspecting function includes a wafer-positioning module, an image-capturing module, a die-sucking module, a die defect analyzing module, a die-classifying module and a control module. The image-capturing module is disposed beside one side of the wafer-positioning module in order to capture an image of each die. The die-sucking module is disposed above the wafer-positioning module and the image-capturing module in order to suck each die from the wafer-positioning module to a position above the image-capturing module for capturing a back image of a back surface of each die. The die defect analyzing module is electrically connected to the image-capturing module in order to judge whether the back image of the back surface of each die passes inspection standard.

  • Publication number: 20100149498
    Abstract: An image display apparatus includes a screen, a reflection mirror, an adaptive optics, and a projection unit. The reflection mirror has a reflective surface facing a light incident surface of the screen, and is separated from the light incident surface by a space. The boundary of the space is defined by the edges of the reflective surface and the light incident surface. The adaptive optics is disposed on the boundary of the space. The projection unit is disposed outside the space. The adaptive optics has a light exit side facing the reflective surface of the reflection mirror, and a light incident side facing the projection unit. A projecting light is generated from the projection unit, passes through the adaptive optics for adjusting the image size formed by the projecting light, and then is projected to the reflective surface of the reflection mirror for being reflected to the light incident surface.

  • Patent number: 7677758
    Abstract: An illumination system is provided, which provides a plurality of light beams to a light valve. The illumination system includes a plurality of light sources, a polynomial lens and an optical scanning element. The light sources are capable of emitting the light beams. The polynomial lens is disposed on light paths of the light beams and located between the light sources and the light valve. The polynomial lens shapes the light beams into a plurality of rectangular light beams. The optical scanning element is disposed on light paths of the rectangular light beams and located between the polynomial lens and the light valve. The optical scanning element is capable of moving for scanning the rectangular light beams on the light valve unidirectionally or back and forth along a direction, and the rectangular light beams partially overlap with each other on the light valve.

  • Publication number: 20090213474
    Abstract: An optical object distance simulation device for reducing total optical path includes: a lens, an achromatic lens set, a first image lens, and a second image lens. The achromatic lens set disposes beside one side of the lens, the first image lens disposes beside one side of the achromatic lens set, and the second image lens disposes beside one side of the first image lens. The achromatic lens set is composed of a first lens and a second lens. The first lens is a double-concave lens. The second lens is a double-convex lens. One concave face of the double-concave tightly contacts with one convex face of the double-convex lens. Therefore, the lens, the achromatic lens set, the first image lens, and the second image lens match with each other in order to simulate real object distance for reducing an object distance between a test camera lens and a corresponding chart.

  • Patent number: 7578730
    Abstract: The present invention discloses a grinding brush fixing device applying to a pneumatic tool for surface treatment. The spacing between the fixing arms and arc plates of the brush holder is reduced. Thereby, the press-fit face of the axially-extending fixing arm can press the brush collar onto the first press-fit edge and second press-fit edge, which are at two sides of the notches between two axially-extending arc plates. Further, a flexible gasket is radially placed in a space between the fixing arms and the arc plates. When the fixing disc is fastened to the brush holder, the flexible gasket and the brush collar are tightly compressed and firmly secured. Thus, force can be uniformly applied onto the brush collar and the bristles. The present invention can promote the stability of brush's rotation, generate straighter ground strips, prolong the durability of the grinding brush and grinding brush fixing device, and promote the grinding efficiency.

  • Publication number: 20090190124
    Abstract: A uniform light generating system for testing an image-sensing device includes a light-generating unit, a light-transmitting unit, a light-diffusing unit, and a lens unit. The light-generating unit has a substrate and a plurality of light-emitting elements electrically disposed on the substrate. The light-transmitting unit has one side communicated with the light-generating unit for receiving and uniformizing light beams projected from the light-emitting elements. The light-diffusing unit has one side disposed on the other side of the light-transmitting unit for receiving and diffusing the light beams that have passed through the light-transmitting unit. The lens unit is disposed on the other side of the light-diffusing unit for transmitting the light beams that have passed through the light-diffusing unit to the image-sensing device.

  • Publication number: 20090020003
    Abstract: An anchor structure of a rotation directing valve is used on a housing made from a composite material for pneumatic tools. A valve bushing in the housing is set under a cylinder. The rotation directing valve held by the valve bushing is to control a pneumatic motor in clockwise or counterclockwise rotation by moving it back and forth to alter the flow direction of compressed air. The anchor structure formed on the valve bushing anchors the rotation directing valve while the pneumatic motor rotates clockwise or counterclockwise.
