Patent number: 8596397Abstract: A supporting portion of an inverter bracket is made of cast, and the inverter bracket is attached onto the side member to locate a vehicle rear end portion of the attachment portion to be on the front side in the vehicle, by a prescribed distance from a vehicle front surface portion of the suspension tower. When a force F is exerted from the front side of the vehicle, the side member curves outward in the vehicle width direction between one part to which the suspension tower is coupled and another part to which the inverter bracket is attached. The inverter bracket and inverter are pushed obliquely outward in the vehicle width direction, so that the contact with the master cylinder can be suppressed.Type: GrantFiled: July 24, 2012Date of Patent: December 3, 2013Assignee: Suzuki Motor CorporationInventor: Tetsuo Sakamoto

Patent number: 6496651Abstract: An exposure control method and apparatus for a camera having a two-area divided brightness measurement system. A central light value is determined based on a central area brightness of a photographic scene, and a peripheral light value is determined based on a peripheral area brightness of the scene. After determining by comparison between the central and peripheral light values whether the scene is back-lighted or front-lighted, a correction coefficient specific to back-lighted scenes or that specific to front-lighted scenes is read from a memory. An exposure value suitable for a main subject is calculated according to the following equation: Es=log2{1−(1−&agr;)2LVb−LVa}−log2&agr;+LVa wherein Es represents the exposure value and &agr; represents the correction coefficient.Type: GrantFiled: March 29, 2002Date of Patent: December 17, 2002Assignee: Fuji Photo Film Co., Ltd.Inventors: Fumio Ishihara, Mutsumi Naruse, Takanori Kohno, Tetsuo Sakamoto, Kouichi Kobayashi, Teruyuki Tongu, Norifumi Nakagawa, Tomio Kurosu

Publication number: 20020021895Abstract: A camera has a movable lens barrel that is stowed in a camera body while the camera is inactive, and is protruded from the camera body to a near range focusing position or a far range focusing position by rotating a drive ring in one direction. The movable barrel returns to the stowed position by rotating the drive ring further in the same direction, because of a cam mechanism interconnecting the drive ring with the movable barrel. To rotate the drive ring, a rotational power of a motor in a first direction is transmitted to the drive ring through a clutch mechanism. The clutch mechanism is switched over according to the rotational direction of the motor and transmits a rotational power of the motor in a second direction to another mechanism. A controller controls driving the motor in response to signals entered through manually operated members, including a power switch, a shutter button and a zone selector, with reference to detection signals from a barrel position detector.Type: ApplicationFiled: December 19, 2000Publication date: February 21, 2002Applicant: Fuji Photo Film Co., Ltd.Inventors: Masaharu Kanai, Ko Aosaki, Hiroshi Soma, Mutsumi Naruse, Toshihiko Izaki, Yukitaka Takeshita, Masao Nakamori, Tetsuo Sakamoto
