Patent number: 11454539Abstract: A vehicle lamp includes: a first light source configured to irradiate visible light; a second light source configured to emit infrared light; a rotating reflector configured to be rotated while reflecting the visible light and the infrared light, and scan the visible light and the infrared light along a horizontal direction on a virtual vertical screen; a light receiving unit configured to receive the infrared light emitted from the second light source and reflected by a target object; and a controller configured to control an irradiation area of the visible light based on the infrared light received by the receiving unit. When determined that there is an abnormality in at least one of the second light source or the light receiving unit, the controller is configured to control the irradiation area based on the surrounding information of the vehicle obtained from outside the vehicle lamp.Type: GrantFiled: April 7, 2020Date of Patent: September 27, 2022Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Fahin Syed Ahmed, Takao Muramatsu, Hitoshi Gotoh

Patent number: 8521466Abstract: A method for determination of interface particles used in a particle method is proposed. According to the present invention, the method for determination includes a density acquiring step of acquiring density in a predetermined range based on a determining-target particle, a first discriminating step of comparing the density with a predetermined threshold, a second discriminating step of determining a symmetry of an arrangement of the other particles within a predetermined range based on the determining-target particle, and a determining step of determining the determining-target particle as an interface particle in the case that the density determined by the first discriminating step is found to be smaller than the predetermined threshold and the arrangement of the other particles determined by the second discriminating step is found to be asymmetrical.Type: GrantFiled: September 8, 2009Date of Patent: August 27, 2013Assignee: Kyoto UniversityInventors: Hitoshi Gotoh, Abbas Khayyer

Patent number: 5266857Abstract: An output-terminal device for an a.c. generator for a vehicle has a connecting seat which is provided at a connecting portion formed in an output side heat sink in a rectifier device attached to the rear bracket of the generator. When an output-terminal bolt extends in the lateral direction, an output-terminal bolt, which has a flat portion at the rear end portion, a polygonal flange portion at an intermediate portion and a threaded portion for connecting a terminal of an external wire at the front end portion, is attached to the connecting seat at its flat portion so as to extend in the lateral direction of the rear bracket. When an output-terminal bolt extends in the rear direction, the output-terminal bolt, which has first and second threaded portions at its rear and front end portions, is fixed to the connecting seat by inserting the rear end portion of the bolt in an opening formed in the connecting seat.Type: GrantFiled: June 16, 1992Date of Patent: November 30, 1993Assignee: Mitsubishi Denki K.K.Inventor: Hitoshi Gotoh

Patent number: 5245241Abstract: A brush unit having a brush, a lead extending from the brush, a metal terminal plate connected to the lead, and a compression spring interposed between the brush and the metal terminal plate. The brush unit is assembled in advance of mounting the brush unit within a blush box. Thereafter, the brush unit is inserted into and held by the brush box through a solder connection between the metal terminal plate and an electrode portion projecting from the brush box. Accordingly, the brush can be easily assembled within the brush box.Type: GrantFiled: September 25, 1991Date of Patent: September 14, 1993Assignee: Mitsubishi Denki K.K.Inventor: Hitoshi Gotoh

Patent number: 5229675Abstract: An output-terminal device for an a.c. generator for a vehicle includes an output-terminal bolt which has a flat portion at its rear end, a polygonal flange portion at an intermediate portion and a threaded portion at its front end. The output-terminal bolt is connected at its flat portion to a connecting seat which is extended from an output side heat sink of a rectifier device attached to the rear bracket of the a.c. generator. An insulation cover is fitted to the rear bracket and supports an insulation terminal socket provided with a cylindrical portion at which bottom portion a polygonal opening is formed. The polygonal flange portion of the output-terminal bolt is fitted to the polygonal opening.Type: GrantFiled: June 16, 1992Date of Patent: July 20, 1993Assignee: Mitsubishi Denki K.K.Inventor: Hitoshi Gotoh
