The device includes a single laser diode for emitting a laser beam having an output power level that is dependent on a driving current supplied to the laser diode. Two laser diode drivers are connected to the single laser diode and can be individually energized to drive the single laser diode to emit a laser beam that can have different output power levels. A selector is connected to the drivers for producing one of a plurality of selecting signals corresponding to the different output power levels, respectively, to select and energize one of the drivers.

摘要： The method disclosed here comprises the steps of (a) mixing metal powder, a resin, abrasive grains, and a solid reducing agent at the normal (room) temperature through the melting point of the reducing agent to form a mixture and (b) molding and baking the mixture at the melting point of the reducing agent through that of the metal powder. The solid reducing agent is a fatty acid, preferably stearic acid having a volume ratio of 5 to 20% with respect to the metal powder. With is, it is possible to make metal-resin bond grindstones that give such high-quality mirror surfaces that have conductivity fit for ELID grinding and are not liable to have chippings or scratches and also have an Rmax value of approximately 3 nm or less.

摘要： A column filter using bundles of long fibers is disclosed. The bundles of long fibers are fixed at their lower end portions but are free-standing at their upper end portions. The length of the fibers in the bundles may preferably be longer than 1,000 mm but shorter than 3,000 mm--especially longer than 2,000 mm but shorter than 3,000 mm. During operation, the bundles may be compressed to a height of 80-30%, generally 50-40% of their original height. A plurality of holders for the respective bundles of long fibers, each of said holders being formed of a cap and a tube communicating to each other, said cap defining orifices and said tube defining a slot through a side wall and opening at both upper and lower ends, may preferably be provided on a perforated plate arranged transversely in a lower interior part of the shell with the cap being located above the perforated plate and the tube being positioned below the perforated plate. The holders cover substantially all perforations of the perforated plate. The lower end portion of each of the bundles is fixed to a lower periphery of a side wall of the associated cap.
