Abstract: PROBLEM TO BE SOLVED: To provide an optical component capable of reducing a sliding resistance on a sliding surface without applying a lubricant and advantageous for stabilizing the operation. SOLUTION: The optical component 10 is a diaphragm which is incorporated into a photographing optical system such as a digital steel camera and digital video camera and is provided with a plurality of aperture blades 16 of changing aperture area. The sliding surfaces are both surfaces in the thickness direction of the aperture blade 16. The plurality of aperture blades 16 are formed of a thin plate-like synthetic resin which does not transmit light and are surface-modified according to a plasma ion implantation method. Accordingly, in the plurality of aperture blades 16, the surface hardness is enhanced, thereby, the friction coefficient of a sliding surface of each aperture blade 16 is lowered thereby reducing a sliding load. As a result, opening/closing operation is stabilized and is made high-speed. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To obtain an apparatus and a method in which a film having a desired film quality and a desired film thickness can be formed always stably, by a method wherein the intensity of a magnetic field generated on the surface of an object to-be-filmed is adjusted on the basis of a change in the crystal state of a detected film, the density of a plasma is controlled and the crystallization of a film to be deposited on the object to-be-filmed is promoted. SOLUTION: In a control part 11, the crystal state of SiO2 particles to be deposited on the surface of a glass substrate 4 is detected on the basis of scattered light in which an electron beam radiated from an electron beam source 27 is reflected on the surface of the glass substrate 4 so as to be fetched by a detector 28, and whether crystallization of a film progresses or not is judged. When a negative result is obtained, the control part 11 controls a variable cathode power supply 23 in order to promote crystallization of the film, and a reference voltage which is supplied to a coil 21 is raised by a prescribed level. Then, the control part 11 detects the crystal state of the SiO2 particles, and it continues the same treatment. As a result, a film which has a desired film quality and a desired film thickness can be formed always stably with a simple constitution.

Abstract: PROBLEM TO BE SOLVED: To obtain a stable plasma generating condition and to maintain a good product quality by providing the ultraviolet ray leaking preventing means which is provided on the prescribed surface of a plasma generating means and prevents the leaking of the ultraviolet rays to the external that are generated when plasma is generated by the plasma generating means. SOLUTION: A plasma beam emitting section 21 is provided on an 'O' ring 6 with an ultraviolet ray leaking preventive layer 22 which is made by alternatively laminating highly refractive layers 22A made of an electrically conductive high refraction material such as TiO2 and low refractive layers 22B made of an electrically conductive low refraction material such as SiO2 . Then, a protective layer 24 is laminated on the layer 22 through an insulating layer 23 to constitute of a display 20. On the display 20, the ultraviolet rays, which are generated when plasma 13 is generated by the section 21, are successively attenuated by the light interference in the layers 22A and 22B of the layer 22. Thus, the leaking of the rays to the external is prevented.
