  • Publication number: 20160121448
    Abstract: A guiding apparatus for sharpening woodworking cutters contains: a holder and an accommodation assembly. The holder clamps a cutter and tilts relative to a grinding plane to form a grinding angle between the holder and the grinding plane. The holder includes a rolling sleeve and an outlet defined between two front ends of two sides thereof to extend a cutting tip of the cutter out of the outlet at an extending distance. The accommodation assembly is joined with the holder and includes a positioning plate. The positioning plate has a stopping extension formed on a rear end thereof to stop the cutting tip of the cutter and has a distance indicator arranged on a top surface thereof adjacent to the stopping extension and with respect to the grinding angle, such that the distance indicator indicates the extending distance at which the cutting tip extends out of the outlet.

  • Publication number: 20080123367
    Abstract: A light source unit for use in a backlight module includes a circuit substrate board and a plurality of chip assemblies arranged along a first direction of the circuit substrate board. Each of the chip assemblies includes a red LED chip, a blue LED chip, and a green LED chip. By employing a chip on board (COB) concept, and by providing LED chips of three primary colors directly on the circuit substrate board, chip spacing can be considerably reduced to effectively shorten the light mixing distance so as to permit miniaturization of the backlight module incorporating the light source unit.
