Title: Separating element for polarized light and its production
Inventor: TAKEDA TADASHI
IPC: G11B7/1353
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive separating element for polarized light and an optical pickup and to provide a production method of the optical separating element for polarized light without using an optically isotropic substrate such as lithium niobate and titanium oxide. SOLUTION: The separating element 10 for polarized light 10 consists of an optical glass substrate 11 and a polydiacetylene oriented film 12a as a double refraction material layer 12. The polydiacetylene oriented film 12a is irradiated with UV rays in a specified pattern to form a periodical grating 12b comprising a part 121 where the hue is changed and a part 122 where the hue is not changed. Therefore, the refractive index periodically changes between high and low in the orienting direction of the polydiacetylene oriented film 12a, while the refractive index hardly changes in the direction perpendicular to that. Thereby, the polarized light in the orienting direction is diffracted while the polarized light perpendicular to that transmits. The obtd. separating element 10 for polarized light can be used as an optical device of an optical pickup.

Abstract: PURPOSE: To reduce a change of a detection level to an input with a declination and to improve the detection performance in a collision in the oblique direction by rotatably supporting a speed detector at the position that does not agree with its center of gravity.  
     CONSTITUTION: The speed detector 1 is installed in the internal space of the base 2 and is rotatably supported by the axis 6 through the bearing 5. When a car is slowed down less than a fixed level in the direction Y-Y, the movable inertia body 11 gives energy to the coil spring 13 while it moves due to acceleration in the direction Y-Y, and comes in contact with the contacts 121, 122 to close the switch.
