Title: Beam section changing optical system, optical pickup device and optical disk driver
Inventor: AKIYAMA HIROSHI
IPC: G11B7/135
Filed: 2001-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a beam shaping optical system which is hardly affected by a temperature change. SOLUTION: A collimating lens 403 is held in a cell 404 and is installed at the bottom of a housing 401 by aligning its optical axis to a light source 402. A glass material which is negative in a refractive index temperature change dn/dt is used for the glass material of the collimating lens 403, by which the component of the focal length of the collimating lens 403 changed by thermal expansion is canceled by the change in the refractive index and the quality of the collimating light not dependent upon the temperature change is obtained. The beam shaping optical system which is tolerant to the temperature change and is highly reliable can be thereby realized. When an LD is used for the light source 402, a light emission wavelength fluctuates by accompanying the temperature change and the change in the focal length of the collimating lens 403 is canceled by the refractive index change of the lens glass material by this wavelength fluctuation and the refractive index change of the collimating lens glass material by the temperature, by which the quality of the collimating light not dependent upon the temperature change can be obtained.

Title: Self-cleanable beam-condensing reflector and solar light collecting power generator
Inventor: YOSHIDA MITSUO
IPC: G02B5/10
Filed: 2001-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a beam-condensing reflector which is capable of preventing the degradation in the reflection luminance of the reflector by the random reflection by dew condensation and water drops and the deposition, etc., of contaminants by dust, etc., without carrying out maintenance over a long period. SOLUTION: A photocatalyst-containing layer is formed on the outside surface on the reflecting surface side of the reflector having beam condensability, as a result of which the photocatalyst of this layer is activated and is hydrophilized when irradiated with UV rays and short wavelengths visible rays. Even if not only the hydrophilic contaminants but the lipophilic contaminants adhere thereto, the water by rainfall, etc., intrudes between the hydrophilized surface and the contaminants to float the contaminants, thereby making the contaminants hardly adherable. Even if the contaminants adhere to the surface, the contaminants are easily flushed away by the rainfall, etc.  The photocatalyst is activated by the irradiation with the UV rays and short wavelength visible rays to manifest strong oxidation power and therefor the deposited contaminants are easily decomposed and are more easily flushed away by the rainfall, etc.
