    摘要： To read information from a target information recording surface reliably by canceling DC offsets in tracking-signal detection signals is provided. In effecting tracking servo by 3-beam method, auxiliary light receiving domains D3—1, D3—2, D8—1, D8—2 are provided. The auxiliary light receiving domain receives images formed by the light returned from a different information recording surface from the one targeted for reading. Sub beams of ± first-order diffracted light enter the light receiving domains D3, D8, D1, D10. With respect to the diffraction direction of the hologram, the auxiliary light receiving domains D3—1, D3—2 (D8 1, D8—2) are provided on both sides of the light receiving domain D3 (D8). Since signals are computed as: D8-(D8—1+D8—2); and D3-(D3—1+D3—2) with the internal connection, DC offsets can be canceled in RES signals (D1+D3, D8+D10) used in the DPP method.

    摘要： In this semiconductor laser device, a polarization hologram transmits an outgoing beam directed from a semiconductor laser chip to an optical disk as a forward beam without diffracting the beam, and diffracts a backward beam of the laser beam, which is a return beam of the forward beam that has been reflected by the optical disk, so that the backward beam is deflected from a direction directed toward the semiconductor laser chip part and further directed toward first, second photoreception parts. Therefore, optical loss on the forward way from the semiconductor laser chip to the optical disk can be reduced, and return light to the semiconductor laser chip can be suppressed, so that a high-power, high-sensitivity semiconductor laser device can be realized.

    摘要： A wire feeding device for use in a multi-wire saw wherein a single wire, one end of which is connected to a feed reel, the other is connected to a collecting reel, is spirally wound between at least two work rollers arranged in parallel, a fixed distance apart, so that turns of the spirally wound wire are separated at predetermined intervals, is constructed so that the feeding speed v of the wire in the process of cutting a workpiece is controlled in association with the variation of the contact length l.sub.X of the wire with the workpiece in the process of cutting the workpiece. Thus, it is possible to maintain the abraded amount of the wire at constant at all cutting sites in the workpiece to be cut, and furthermore, the waste removed at cutting can become the same throughout the entire part of each cutting plane, so that the thickness can be uniform within the surface of the sliced piece.
