  • Patent number: 8890055
    Abstract: A method of producing a solid-state imaging device includes the steps of forming on a substrate a photoelectric conversion portion that receives light on a light-receiving surface and that photoelectrically converts the received light to generate a signal charge, forming above the light-receiving surface an optical waveguide that guides light to the light-receiving surface, and forming above the optical waveguide a color filter which colors light and from which colored light is emitted to the optical waveguide, wherein, in forming the color filter, the color filter is formed from a photosensitive resin film containing a dye by performing an exposure process and then performing a development process on the film, and in forming the optical waveguide, a core portion of the optical waveguide is formed so that the core portion absorbs exposure light radiated onto the photosensitive resin film when the exposure process is performed.

  • Patent number: 8872134
    Abstract: Described is a self-indicating instant radiation dosimeter (1001) for monitoring high energy radiations, such as X-ray. The dosimeter contains a radiation sensitive, color changing, indicating composition (10), e.g., a diacetylene (R—C?C—C?C—R?, where R and R? are substituents groups) or a radiochromic dye, a polymeric binder (20) and optionally a shelf life extender (50) or an activator (40). The radiation sensitive composition (10) changes color instantly when exposed to high energy radiation. The dose is estimated by comparing the color with a color reference chart or more accurately with a spectrophotometer or an optical densitometer. The radiation sensitive composition (10) is protected from low energy radiation such as UV light, by a layer of low energy absorbing materials, such as UV absorbers.

  • Publication number: 20040063006
    Abstract: The present invention relates to an optical memory device and an operating process thereof. The optical memory device have a recording layer containing a photochromic compound and an electron-accepting compound which is a Lewis acid compound having a Lewis acid part and a long chain part having carbon atoms of C12 or more. One aspect of the operating process has a recording step which recording is performed on the optical memory device by irradiating visible light corresponding to the absorption band of the colored photochromic compound for recording using decolorizing, before and after recording, heating treatments are performed to control the decolorizing sensitivity of the photochromic compound, and an erasing step which ultraviolet light is irradiated to the area including the recorded portion in order to uniformly color the recording layer again.
