    摘要: A portion (14a, 14b) of a chip remover (14) is defined to be vibratory to give an NC machine tool (MT 1) a vibration transferable onto a surface (FS) of a work (13) under a finishing by the NC machine tool (MT1), a decision is made whether the NC machine tool (MT1) enters the finishing, and vibration of the vibratory portion (14a, 14b) is controlled, as the decision is true. A chip removal method and an NC machine tool equipped with a spiral chip remover (113) as a chip remover have various chip removal rules for determining permission/prohibition of the operation of the spiral chip remover (113). This spiral chip remover (113) operates based on commands described in a machining program. When a command in the machining program is executed, the permission/prohibition of the operation of the spiral chip remover (113) is controlled according to the chip removal rules.

    摘要: A position control apparatus and method has been devised which provides for an improved means of suppressing tracking error from a variable position reference occurring when a control object positioned via a transmission mechanism with mechanical transmission error resumes movement from a state stopped at a target position. A selection between two alternative tracking error compensating means within the control apparatus is made based on whether the detected position of the control object changes in a period after the control object stops and before the variable position reference is input again to a control deviation generating unit.

    摘要: The Si waveguide 305 includes a first conductivity-type Si layer 301 and an intrinsic Si layer 302, and a second conductivity-type light-absorption layer 303 is partially formed on an area thereof. During operation, a reverse bias is applied between the first conductivity-type Si layer 301 and the light-absorption layer 303. Since the light-absorption layer 303 has a conductivity type, it is not depleted when a voltage is applied, but the intrinsic Si layer 302 forming the Si waveguide 305 is depleted. Therefore, it is possible to reduce a CR time constant. Furthermore, since the intrinsic Si layer 302 can be formed on the first conductivity-type Si layer 301 in a continuous manner, it is possible to reduce lattice defects. As a result, it is possible to suppress the dark current generated in the light-receiving element.
