  • Patent number: 6712482
    Abstract: An illumination device 4 includes a light guide 6 which receives light from a light source 7 at a light-receiving face 6a and emits the light from a light-emitting face 6b. A face 6c opposite the light-receiving face 6a of the light guide 6 is formed as an inclined plane. The light which has reached the inclined plane 6c reflects at an angle off the inclined plane 6c. Therefore, the frequency in diffusion of the light increases. As a result, the luminance of the light emitted from the light-emitting face 6b is improved. The luminance of a planar light can be made uniform by varying the shapes of diffusion patterns 12 disposed on a diffusion sheet 9 according to the distance from the inclined plane 6c.

  • Patent number: 5429711
    Abstract: There is disclosed a wafer-manufacturing method in which a single crystal ingot is first sliced into a plurality of wafers, and both surfaces of each wafer are subjected to grinding or lapping operation. Then, the front and back surfaces of the wafer are subjected to etching. Thereafter, the back surface of the wafer is subjected to chemical mechanical polishing to half-polish the same, following which the wafer is placed on a polishing machine, with the half-polished back surface of the wafer being adhered to a carrier plate; and the front surface of the wafer is mirror-polished. In the foregoing, a polysilicon film for extrinsic gettering may be formed on the back surface of the etched wafer prior to the half-polishing.

  • Patent number: 5242642
    Abstract: A switch substrate for a switching device that includes an electrical contact brush, the substrate formed with alternating conductive and insulating portions on its surface and having a groove formed between the conductive and insulating portions to eliminate insulating abrasion powder from the surface of the contact brush. The top of the conducting portions is higher than the bottom of the groove but can be above or below the surface of the insulating portions. To form such a substrate, a conductive layer having projections is formed and is engaged with a mold so that the projections are compressed. After the substrate is removed from the mold, the compressed projections extend to their actual height.
