Patent number: 8558683Abstract: A display apparatus for a vehicle includes: a display element; an image generation element for generating a vehicle image, an analog image and an indication image; and a display controller. The analog image includes an indication position and multiple indexes arranged on an upside and downside of the indication position. The indication image shows the current vehicle speed at the indication position. Each index shows a corresponding vehicle speed. Display dimensions of each index are inverse proportion to the corresponding vehicle speed, and a distance between the indication position and each index is proportion to a difference between the current vehicle speed and the corresponding vehicle speed. The display controller controls the display element to display the indication image at the indication position of the analog image.Type: GrantFiled: March 24, 2010Date of Patent: October 15, 2013Assignee: Denso CorporationInventors: Ryoichi Nishikawa, Yasuhisa Yamashita, Hiroki Matsui, Takaaki Muramatsu, Kenichirou Karikomi, Tomoyuki Miyagaki, Hitoshi Sugiyama

Patent number: 8466633Abstract: An illumination controlling device for a vehicle includes a controlling portion to change a luminance phase of a meter based on operation of an operating portion and to maintain a luminance phase of a lighting while the lighting is extinguished. The controlling portion changes the luminance phase of the meter based on the operation of the operating portion and changes the luminance phase of the lighting to correspond to the luminance phase of the meter if the operating portion is operated in a state that the luminance phase is different between the meter and the lighting while the lighting is illuminated.Type: GrantFiled: February 23, 2011Date of Patent: June 18, 2013Assignees: DENSO CORPORATION, Toyota Jidosha Kabushiki KaishaInventors: Masayuki Sugiura, Takaaki Muramatsu, Atsushi Nishiyama, Ryuji Suzuki, Shinji Suganuma

Patent number: 8160298Abstract: A display device includes a display panel and a control unit. The control unit is configured to control a display condition of the display panel by successively switching a plurality of frames, thereby to display a pointer image indicating a pointer and a path image indicating a path of motion of the pointer image. The path image of a first frame, which is any one of the plurality of frames, is provided continuously from a second location where the pointer image of a second frame, which is another one of the multiple frames and immediately before the first frame, is displayed to a first location where the pointer image of the first frame is displayed.Type: GrantFiled: October 20, 2008Date of Patent: April 17, 2012Assignees: Denso Corporation, Toyota Jidosha Kabushiki KaishaInventors: Tomohiro Okumura, Ryoichi Nishikawa, Takaaki Muramatsu, Shinji Suganuma

Patent number: 7997776Abstract: An indicating instrument for a vehicle has a display board and a light modulation member disposed to cover a surface of the display board. When a condition that an illumination intensity of the display board is lower than a threshold value has continued for a first time period, a light transmissivity of the light modulation member is controlled to a first level so that a driver can easily see the display board. When a condition that the illumination intensity of the display board is equal to or higher than the threshold value has continued for a second time period, the light transmissivity of the light modulation member is controlled to a second level that is lower than the first level to restrict entry of external light to the display board.Type: GrantFiled: March 9, 2006Date of Patent: August 16, 2011Assignee: Denso CorporationInventors: Takaaki Muramatsu, Toshiki Wada

Patent number: 7523798Abstract: The duct comprises the upper member and the lower member, which are formed separately and assembled integrally by being attached to one another. There is provided the seal member to interconnect the opening at the lower member and the intercooler, which is pressed against the upper face of the intercooler. The front side of the lower member is supported at the shroud panel, and the rear side of the upper panel is supported at the cowl panel. Thus, the rear attachment portion is detached earlier than the front attachment portion at the pedestrian's hit. Accordingly, the duct can be split surely and the engine hood can be allowed to be properly deformed without being prevented, so that the protection of the head of pedestrians can be attained properly.Type: GrantFiled: August 3, 2005Date of Patent: April 28, 2009Assignee: Mazda Motor CorporationInventors: Takaaki Muramatsu, Takashi Kadowaki, Noriaki Fujita

Patent number: 6986260Abstract: An electric fan system has a first electric blower 10, which utilizes a brushless motor, and a second electric blower, which utilizes a brushed motor, for distributing the cooling air to the radiator and the condenser. The system has an electronic engine control unit which activates only the first electric blower when it determines that the cooling water temperature is less than T2, and activates both the first and second electric blowers when it determines that the cooling water temperature is T2 or higher. The water temperature is based on a detection output from a cooling water temperature sensor. Thus, since the electric blower is not activated unless the cooling water temperature becomes T2 or higher, use of the brushed motor is limited and its life is increased.Type: GrantFiled: July 8, 2004Date of Patent: January 17, 2006Assignees: DENSO Corporation, Asmo Co., Ltd.Inventors: Shinichi Oda, Kuzuhiro Takeuchi, Tatsuhiro Matsuki, Takaaki Muramatsu

Patent number: 6966663Abstract: An automotive instrument includes a light transmission controller and a mode selecting switch. The controller controls light transmission of a light-controllable film according to a selected position of the mode selecting switch. The mode selecting switch has three positions: two manual mode positions and an automatic mode position. The manual mode positions are provided for adjusting the light transmission to a fixed level. The automatic mode position is provided for controlling the light transmission so that a dial plate maintains a predetermined level of visibility. The dial plate can be switched between different appearances. This switching can be performed during the vehicle is in operation based on the driver's preference.Type: GrantFiled: October 9, 2003Date of Patent: November 22, 2005Assignee: Denso CorporationInventors: Toshiki Wada, Takaaki Muramatsu, Katsuhiro Kumazawa
