摘要： An optical pickup includes a lens holder holding an objective lens for converging a light beam on a signal recording layer of an optical disk; elastic support members supporting the lens holder such that the lens holder can freely move in three driving directions, i.e., a tracking direction, a focusing direction, and a tilting direction; a pair of coil units attached to two sides of the lens holder, the two sides being spaced in a tangential direction orthogonal to the focusing direction and tracking direction; and a pair of magnets arranged to face the corresponding coil units. Each coil unit includes a tracking coil, a focusing coil, and a tilting coil for driving the lens holder in the three driving directions. The focusing coil and the tilting coil are formed by winding a focusing conductor of the focusing coil and a tilting conductor of the tilting coil together in parallel.

摘要： A liquid crystal display device includes a liquid crystal display cell including lamination of a lower polarizer, a first glass substrate having a metal oxide glass film formed on the side of the lower polarizer, a liquid crystal layer, a second glass substrate having a metal oxide glass film formed on the side opposite the liquid crystal layer, and an upper polarizer; and a backlight unit including a light guide plate, a diffusion plate, and light sources. The metal oxide glass films are a transparent film made of an organic/inorganic hybrid material. The films are formed by coating a solution of a metal alkoxide composition on individual outer surfaces of the first glass substrate and the second glass substrate, both of which have been roughened by a polishing process, and by hydrolyzing and curing the metal alkoxide composition.

摘要： The present invention provides an objective-lens driving apparatus in which the phase delay is small in focusing-response characteristic and which excels in resonance characteristic in high-frequency bands. The objective-lens driving apparatus includes a movable unit that has a lens holder holding an objective lens, a fixed unit that is spaced apart from the movable unit in a tangential direction, elastic support members that support the movable unit, enabling the movable unit to move with respect to the fixed unit in the focusing direction and tracking direction and to incline in a tilt direction, a first magnet, and a second magnet that is magnetized in a direction opposite to a magnetization direction of the first magnet. The lens holder has tracking coils, focusing coils, a first tilt coil that is wound around an axis extending in the focusing direction and generates drive forces acting in the tilt direction, and a second tilt coil that is wound around in a direction opposite to the winding direction of the first tilt coil, and generates drive forces acting in the tilt direction.

摘要： An abrading machine and abrading method are provided which permit a workpiece to be abraded without damage even in the case of heavy stock removal. A work holding member for mechanical abrasion includes a first holding member with a hole for receiving a workpiece and which transmits external drive force to the workpiece, and a second holding member placed on the first holding member and also having a hole for receiving the workpiece. The second holding member is removed after a predetermined volume of stock is abraded away; the workpiece is then abraded to a target thickness while being held by the first holding member alone. Thicknesses t1 and t2 of the first and second holding members are given by T1>t1+t2 and (½)T2≦t1, where T1 and T2 represent the workpiece thickness before and after abrasion, respectively.
