Title: Transmission type diffraction element and optical pickup device
Inventor: HAYASHI KENICHI
IPC: G11B7/135
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To provide a transmission type diffraction element capable of preventing the generation of reflected diffracted light without forming an antireflection film on the surface of a cyclic grating. SOLUTION: The reflection coefficients of the surfaces 41 and 51 of a recessed part 4 and a projection part 5 for constituting a cyclic grating 3 of this transmission type diffraction element 1 are set to be almost equal. The depth (d) of the recessed part 4 is set to be the integral multiple of 1/2 of the wavelength of light L0 made incident from the side of a first surface 21. Thus, the phase difference of the light L4 reflected from the surface 41 of the recessed part 4 and the light L5 reflected from the surface 51 of the projection part 5 among the incident light L0 becomes the integral multiple of 2π and the reflected diffracted light is not generated. Therefore, the transmission type diffraction element capable of preventing the generation of the reflected diffracted light without forming the antireflection film on the surface of the cyclic grating 3 is realized.

Title: Single crystal growing method on insulating film
Inventor: KAWAMURA SEIICHIRO
IPC: H01L21/205
Filed: 1985-05-13
Abstract: PURPOSE:To obtain an SOI structure which can be readily manufactured in a mass production by laminating an insulating layer on a silicon substrate, epitaxially growing by a reduced pressure vapor phase reaction with mixture gas of dichlorosilane and hydrochloride, coating the entire surface with the epitaxially grown layer, thereby readily growing a lateral single crystal on the insulating film. CONSTITUTION:A silicon substrate 1 and an insulating film 2 laminated on the substrate are patterened. Then, with gas mixed with dichlorosilane SiH2Cl2 and HC used as reaction gas of epitaxial growth an epitaxial growth is performed. Then, the substrate is heated and reacted by a low pressure CVD method. A vertical epitaxial growth is performed by this reaction. Thus, growths are advanced on both sides of the insulating film to form an epitaxial growth layers coated with the films on the entire surface. Since the growth is mostly delayed on the center line of the film, the grown layer is thin to form a recess. The irregular surface is eliminated by a mechanical polishing method, or laser emitting and sweeping, thereby melting to flatten the surface by quick heating and quick cooling.

Title: Structure for mounting electric discharge lamp stabilizer
Inventor: HORIBE SHUICHIRO
IPC: H01F37/00
Filed: 1987-04-24
Abstract: PURPOSE:To enable an electric discharge lamp stabilizer to be mounted at a lower level and to prevent insects or the like from entering into the stabilizer from a gap defined between an apparatus body and elastic support pieces, by displacing the elastic support pieces, prior to mounting the stabilizer, in the direction opposite to the direction of deflection caused by a weight of the stabilizer so that the elastic support pieces rest at the level flush with the apparatus body after mounting the stabilizer. CONSTITUTION:Elastic support pieces 3, 3 are initially displaced in the direction opposite to the deflecting direction, namely they are displaced upwards by an amount of deflection which would be caused by a weight of an electric discharge lamp stabilizer 4 exerted thereto when the stabilizer 4 is mounted on a stabilizer mounting table 5. As a result, even if the elastic support pieces 3, 3 are deflected downwards by the weight of the electric discharge lamp stabilizer 4 when it is mounted on the stabilizer mounting table 5 of an apparatus body 1, the elastic support pieces 3, 3 rest at the level flush with the apparatus body 1. Accordingly, there is no need of mounting the stabilizer 4 at a higher level. Further, a gap defined between the apparatus body 1 and the elastic support pieces 3 is originated from a notch 2 only. Therefore, if the notch 2 is formed sufficiently narrow, it is possible to prevent insects from entering the stabilizer from the gap.

Title: Control device for shock absorber
Inventor: SHIRASU TAKASHI
IPC: B60G17/00
Filed: 1986-05-01
Abstract: PURPOSE:To improve driving comfortableness, by judging whether or not a detected ground clearance is above the predetermined value when the vertical movement of a car body is displaced in the neutral ground clearance direction, and increasing the damping force when the ground clearance is above the predetermined value in a control device for a damping force variable shock absorber. CONSTITUTION:Respective ground clearance are detected by a ground clearance sensor M1 so as to be input into a control means M3. ECU of the control means M3 judges whether or not a detected ground clearance M1 is above the predetermined value, at the specified timing when the vertical movement in a car body is displaced in the neutral ground clearance direction. When the detecting ground clearance is above the predetermined value, a command is output to a damping force change means M2 in such a way as further increasing the damping force. Therefore, the damping force of a shock absorber is changed by the damping force change means M2. With this arrangement, it is possible to speedily return the ground clearance at the neutral position within a half period of body vibration so as to improve driving comfortableness.
