摘要： An optical information apparatus of the present invention includes: an optical pick-up head including: a light source; a diffraction unit; a condensing unit; a beam splitter; a photodetector; and a tracking error signal generator. An optical recording medium has tracks arranged substantially at a constant pitch. An average of a pitch is tp. When a main beam is placed on the track, a first sub-beam and a second sub-beam are placed between the tracks. The tracking error signal generator performs a differential arithmetic operation with respect to signals output from a light-receiving portion receiving the main beam to generate a first push-pull signal, performs a differential arithmetic operation with respect to signals output from the light-receiving portions receiving the first sub-beam and the second sub-beam to generate a second push-pull signal, and performs a differential arithmetic operation with respect to the first push-pull signal and the second push-pull signal to generate a tracking error signal, in a case where an amplitude of the first push-pull signal obtained at the pitch tp is fluctuated when the light beam is scanned in a direction orthogonal to the tracks of the optical recording medium.

摘要： A plural color component film laminate part and method for insert-molding a plural color film laminate part comprises preforming a film laminate and subsequently insert-molding a plastic substrate against the preformed film laminate. An improvement in traditional insert molding techniques is provided by use of a specific mold cavity structure which facilitates positioning of the film laminate transition line(s) between colors within longitudinally extending groove(s) in the part show face. According to one embodiment, the film laminate is preformed with a re-entrant edge portion which is positioned within the mold cavity such that the edge of the plastic substrate will be substantially covered. The insert molding step involves positioning the preformed film laminate in a specially configured mold cavity, closing the mold and injecting molten resin into the mold' cavity against the film laminate.

摘要： An object of the present invention is to acquire optimum recording characteristics of an optical recoding medium having multiple data layers, with respect to each of the multiple data layers without increasing learning time required for learning a relation between aberration amount and optimum recording compensation with respect to each of the multiple data layers. The present invention includes a wavefront converter which is driven in such a manner as to reduce the aberration amount detected by an aberration detector. An output controller holds learned data as to the relation between the driving amount of the wavefront converter and the output of a light source, and controls the output of the light source based on the driving amount of the wavefront converter and the learned data.

摘要： A weight 4 which is held by a weight holder 3 in a balancer has a pressing face 4b′ which is pressed against a guide face 12a provided along the circumferential direction of rotation of the weight holder 3 by centrifugal force generated by rotation of a rotary body. When the rotary body rotates, the weight 4 which is pressed against the guide face 12a via the pressing face 4b′ changes its position relative to the rotary body in the circumferential direction of rotation, whereby the weight 4 is disposed in a position in which it suppresses whirling motion of the rotary body. The guide face 12a and pressing face 4b′ are inclined relative to the axial direction of rotation so as to tend to outward side in the diametrical direction of rotation as tending to one side in the axial direction of rotation. The weight 4 is pressed against a receiving portion 7a′ by component of the centrifugal force, in which the component acts along the guide face 12a and pressing face 4b′.

摘要： Method for insert molding film covered plastic parts are disclosed that facilitate wrapping of the paint film around edges of the part. A mold cavity (210) is provided wherein the requisite edge extremities (212, 214) of the cavity (210) are provided in an offset or spaced relation to the mold parting line plane (216). Location of the mold extremities at this position helps to secure the paint film in the mold cavity (210) and prevents pinching of the film that would otherwise occur along the mold parting line (216).
