Heat sinks for semiconductor laser devices are manufactured by processing a surface of a panel into a mirror surface, forming a plurality of substantially parallel photomasks spaced at predetermined intervals on the mirror surface, etching the mirror surface through the photomasks to define grooves, the grooves and the mirror surface jointly providing edges therebetween, removing the photomasks from the panel, and thereafter, cutting the panel along the grooves into a plurality of heat sinks. Each of the heat sinks has a surface having a desired ultrahigh level of surface finish accuracy up its edge, and can be manufactured relatively inexpensively.

Heat sink and method of manufacturing heat sink

A sheet conveying/sorting system which sorts sheets being successively conveyed by a target number of sheets, that is, by a package units. The sheet conveying/sorting system includes a downstream conveyor, an upstream conveyor, sucking conveyor and controller. In the sheet conveying/sorting system, in accordance with a signal output from the control, the successively conveyed sheets are separated from each other and, after separation, the respective parts of the system are returned to their original positions. By repeating these steps sequentially and sucessively, the sheets can be sorted by the package units.
