Abstract: An optical disc drive apparatus includes a reference base. A turntable provided on the reference base operates for receiving an optical disc thereon. An optical pickup head supported by a guide shaft is movable along the guide shaft in a radial direction of the optical disc on the turntable. A movable base supports the guide shaft, and is movably connected to the reference base. The movable base is inclined relative to the reference base at an adjustable inclination angle. A mechanism operates for moving the movable base relative to the reference base and adjusting the inclination angle to correct a tilt of an optical axis of the optical pickup head with respect to an information recording surface of the optical disc on the turntable. A plurality of guide members fixed to the reference base have respective guide surfaces. Guide rollers connected to the guide shaft are in contact with the guide surfaces of the guide members respectively.

Abstract: A centering apparatus and method is provided which automatically measuring the radius or radius deviation of a large cylindrical bore, and shorten the time required for centering. The inspection apparatus is supported on a rise and fall base which is horizontally supported on a top portion of the large cylindrical bore in such a manner that it is allowed to vertically move in parallel with a fine wire which is hung perpendicularly from the center of the top portion. The inspection apparatus having a non-contact type two-dimensional position sensor for detecting the relative position of the fine wire to the cent-er of the inspection apparatus. The inspection apparatus is positioned at an arbitrary height.

Abstract: A wire chain connector for an anchor line has a swivel coupled to a rope socket via a link, and a ball adapter mounted on the outer periphery of the link. A wire rope groove is formed in the inner surface of a peripheral groove in a sheave to allow a wire rope to pass along it. A chain pocket is formed in the central portion of the peripheral groove in the sheave to allow a chain to pass along it. A connector groove is formed in the outer surface of the peripheral groove in the sheave to allow the anchor line to pass along it. The body of the swivel and the ball adapter are so sized that they can be seated in the connector groove.
