摘要： An optical head that detects a tilt in an optical disk. The optical head includes a condensing means, a light receiving means, a tracking error signal detection means, and an optical tilt detecting means. The light receiving means includes at least first and second light receiving areas, the first light receiving area being a rectangle having long sides that extend in a direction perpendicular to information tracks on the optical disk. The tracking error signal detection means detect error signals corresponding to light signals received in the first and second light receiving areas. The optical disk tilt detection means compare the tracking error signals to detect a radial tilt in the optical disk. In an alternative embodiment, the long sides of first light receiving area extend in a direction parallel to the information tracks, and the optical disk tilt detecting means detect a tangential tilt in the optical disk.

摘要： An optical disc apparatus includes a withdrawal means for moving an objective lens (32) to a position distant from an optical disc (1) during an inactive duration of intermittent recording or reproducing operation. A means for regulating or fixing the objective lens (32) at the position distant from the optical disc (1) is further provided. Thus, even in a noncontrolled state during the inactive duration, it is possible to prevent collision of the objective lens (32) with the optical disc (1). As a result, both power saving and safety of the apparatus can be attained.

摘要： Nickel powder includes, on the basis of the total number of particles, not less than 10% of particles whose particle size is not less than 1.2 times the average particle size, as determined by the SEM observation; and not less than 10% of particles whose particle size is not more than 0.8 times the average particle size, as determined by the SEM observation. The nickel powder can be prepared by, for instance, precipitating nickel particles from an aqueous solution containing a nickel salt and a hydrazine reducing agent, without forming any hydroxide of nickel as an intermediate. A conductive paste containing the nickel powder can be applied onto an internal or external electrode for electronic parts.

摘要： A work cutting apparatus in which clearance adjustment is simultaneously possible for the two sides of the L-shape of the blade by a single adjustment operation and in which the elevation system of the movable blade has a simple arrangement. The work cutting apparatus is provided with a fixed blade of which the plan shape is approximately L-shaped, and a movable blade that moves vertically and comprises an approximate l-shape in alignment with the fixed blade. The movable blade is mounted on the tip of a ram that pivots vertically via a pivot support shaft arranged on the lower frame. The pivot support shaft is an eccentric shaft and, by adjusting the rotation of the angle of the shaft, the oscillation center of the ram is changed and the clearance adjustment of the blades is possible. The axial direction of the pivot support shaft is angled with respect to both sides forming the L-shape of the fixed blade and by adjusting only the rotation angle of the pivot support shaft, clearance adjustment of both sides forming the L-shape of the blades may be simultaneously performed.
