    摘要： In relation to a blade cutting stone or concrete, a blade, preventing wearing of a core while preventing the core from wobbling, cuttable at a stable speed is provided. In a blade formed by providing slots on the outer peripheral edge of a circular core and fixing a superabrasive layer to a portion of the outer peripheral surface of the core located between the slots, the superabrasive layer consists of a first superabrasive layer having an extension formed by partially extending the superabrasive layer toward the inner periphery of the core and a second superabrasive layer. A reinforcing superabrasive layer extending from the outer periphery toward the inner periphery of the core is formed on the inner peripheral side of the second superabrasive layer while the reinforcing superabrasive layer is located closer to the outer periphery than a radial central portion of the core, and an outer peripheral end of the reinforcing superabrasive layer is located closer to the outer periphery than an inner peripheral end of the extension of the first superabrasive layer. The second superabrasive layer can also be provided with an extension having a relatively short radial length with respect to the extension of the first superabrasive layer.

    摘要： A blade comprises a disc-shaped substrate having a major surface and an outer peripheral edge portion encircling the major surface, and an abrasive grain layer mounted on the outer peripheral edge portion of the substrate. The substrate includes a first disc having a major surface, and a second disc having a major surface which is superposed on that of the first disc. The major surface of the second disc is separated from that of the first disc, thereby defining a clearance between the major surfaces of the first and second discs and correspondingly forming a convex surface region on the outside surface of the substrate. The peripheral portion of the convex surface region is provided with a contact portion where the major surfaces of the first and second discs are slidably in contact with each other. An adhesion inhibitor is applied to the major surfaces of the first and second discs before superposing these major surfaces with each other, and the outer peripheral edge portions of the superposed first and second discs are covered with a mixed powder of abrasive grains and metal powder. The mixed powder is then sintered, thereby forming the abrasive grain layer which is fixed to the outer peripheral edge portions. The first and second discs are then spot-welded together at a plurality of locations between the major surfaces of the first and second discs.

    摘要： Two motor fans are driven by two 4-pole direct current motors, respectively. Rotational speed of the two motors is controlled in three stages, namely low speed, intermediate speed and high speed. Specifically, at the time of low speed operation the two motors are connected in series with four poles, at the time of intermediate speed operation the two motors are connected in parallel with three poles, and at the time of high speed operation the two motors are connected in parallel with four poles.
