Title: Light guide element
Inventor: WAYNE V SORIN
IPC: G02F1/21
Filed: 2000-06-13
Abstract: PROBLEM TO BE SOLVED: To obtain an optical switching element which operates a light signal independent from a polarizing state of the light signal without causing loss of light intrinsic to a polarization dependent waveguide by using a walk-off crystal to separate the incident light into a plurality of polarized light beams having polarization components perpendicular to each other. SOLUTION: An input light signal is separated by a walk-off crystal 310 into two polarized light beams 308, 309 having polarization components perpendicular to each other. The two polarized light beams 308, 309 enter a pair of switchable waveguides. The waveguide is equipped with a single liquid crystal layer 314. When the light outgoes from the switchable waveguides, the polarization of the light signal on an optical path is rotated by 90 deg. by a polarization rotator 317. Then the two polarized light beams 308, 309 are coupled again by a walk-off crystal 318. in this method, the optical paths where the two separated polarized light beams 308, 309 pass is identical. By this structure, the generation of phase difference between the light signals can be avoided.

Title: Disk device
Inventor: FUJITA MINORU
IPC: G11B17/028
Filed: 2000-06-14
Abstract: PROBLEM TO BE SOLVED: To surely eject and convey a disk such as a DVD or a CD removed from a table even when the disk is deformed. SOLUTION: A disk 504 inserted and conveyed by a disk conveying means is loaded on a table 508 by the lowering of a clamping means 675 by an elevating/lowering means 676. When the table is rotary-driven around its axis 507 by a rotary-driving source 506, the disk is played back by an optical pickup 511. After the playing back when the holder 678 of the clamping means is lifted by the elevating/lowering means, a pair of locking pieces 691 and 692 provided in the holder lifts the bottom part of the outer peripheral edge of a disk 509. Thus, the disk 509 is surely separated from the table 508. Therefore, the disk conveying means surely ejects and conveys the disk. The locking piece is inclined downward so as to approach the disk toward the inner side of a radial direction.  Thus, the locking piece is brought into point-contact with the bottom part of the outer peripheral edge of the disk, and the damage of the disk by the locking piece is prevented.
