Patent number: 11846400Abstract: A vehicle lamp includes: a first light source and a second light source having light emission colors different from each other; and a light guide body that receives and emits light from the first light source and the second light source. The light guide body includes an incident portion on which the light is incident, a reflecting portion that reflects the light incident from the incident portion, and an emitting portion that emits the light reflected by the reflecting portion. The reflecting portion includes a plurality of first light distribution control surfaces that reflects the light from the first light source toward a predetermined direction and a plurality of second light distribution control surfaces that reflects the light from the second light source toward the predetermined direction. The plurality of first and second light distribution control surfaces are alternately arranged.Type: GrantFiled: May 18, 2021Date of Patent: December 19, 2023Assignee: KOITO MANUFACTURING CO., LTD.Inventor: Kimiaki Yoshino

Patent number: 11022742Abstract: A light guide device includes a light guide plate that induces a light emission of a light source. The light guide plate includes an incident portion that is incident light emitted from a light source, a reflecting portion that reflects the light from the incident portion to an inside of the light guide plate, and an emitting portion that emits the light from the reflecting portion to an outside of the light guide plate. The emitting portion is provided in a thin elongated shape on a first portion of a circumferential surface of the light guide plate. The reflecting portion includes an expansion surface that expands the light from the incident portion to a circumferential direction of the light guide plate.Type: GrantFiled: December 7, 2018Date of Patent: June 1, 2021Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Katsuaki Ohtawa, Kimiaki Yoshino

Patent number: 4845021Abstract: An optical recording medium which comprises a substrate and a recording layer of at least two J-aggregates of dyes formed on the substrate is described. The dyes may be photochromic dyes or other types of dyes capable of forming the aggregates which have narrower absorption spectral ranges than original dyes. A plurality of information bits can be written in the recording layer by irradiation of one laser beam spot. The recording layer is formed by an LB film method or a method capable of fluidizing a dye solution in a direction horizontal to the substrate surface. A recording method using the medium is also described.Type: GrantFiled: January 14, 1988Date of Patent: July 4, 1989Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Jinsei Miyazaki, Eiji Ando, Kimiaki Yoshino, Kazuhisa Morimoto

Patent number: 4794068Abstract: An optical recording medium is prepared by the use of spiropyrane whose molecular structure contains an alkyl chain having at least 10 more carbon atoms, and by the use of an LB film method or a spin coating method. This recording medium is of a structure wherein when irradiated with the UV, the spiropyrane is photo-isomerized to photomerocyane and, thereafter, when subsequently heated at 35.degree. to 40.degree. C. for 15 minutes, a J-aggregate of the photomerocyane is formed in very stabilized form. When the recording medium is irradiated with light of wavelength of visible spectrum, the color is bleached with the information consequently recorded. The optical recording medium herein disclosed is rewritable and can retain the recorded information for 5,000 hours or more.Type: GrantFiled: August 31, 1987Date of Patent: December 27, 1988Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Jinsei Miyazaki, Eiji Ando, Kimiaki Yoshino, Kazuhisa Morimoto

Patent number: 4686169Abstract: An optical recording medium comprising a substrate and an information recording layer which consists of monolayer assemblies comprising a photochromic compound of which is based on cis-trans isomerization such as an amphipathic derivative of azobenzene, indigo or thioindigo having a long chain substituent, which monolayers are formed on the substrate by the Langmuir-Blodgett method and oriented in a two-dimensional plain. When the recording medium is irradiated by light, light absorption spectrum of the recording layer changes so that information is recorded. Since the photochromic compound is oriented in a monolayer, its photochromism lasts long.Type: GrantFiled: November 8, 1985Date of Patent: August 11, 1987Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kimiaki Yoshino, Eiji Ando, Jinsei Miyazaki, Kazuhisa Morimoto

Patent number: 4294902Abstract: The present invention is directed to a method and an apparatus for formation of images by particles on a photosensitive plate. Particles employed are translucent, whereby a charge holding the particles to the photosensitive plate may be efficiently removed from selected particles by image-wise light from an original document, etc., so ensuring production of well-defined images. For production of color images, there is employed a panchromatized plate and particles which are transparent to different types of light and have associated therewith dye material permitting production of clearly defined color images, it being made possible to obtain a color copy of an original document in a process requiring only one exposure stage and only one development stage.Type: GrantFiled: August 17, 1978Date of Patent: October 13, 1981Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yuji Takashima, Eisuke Ishida, Hisanori Nishiguchi, Kimiaki Yoshino
