Patent number: 6783073Abstract: An image input system includes a solid state image pickup device and a preprocessor for performing correlated double sampling amplification on an output of the image pickup device and outputting a video signal. The preprocessor has a correlated double sampling amplifier for outputting signal information corresponding to a difference voltage between the black level in a feedthrough period of the image pickup device and a signal level in a charge signal output period; and an offset cancelling circuit for cancelling an offset voltage corresponding to the difference voltage in a state where the image pickup device is optically interrupted to the input terminal of the correlated double sampling amplifier. The correlated double sampling amplifier cancels out the offset voltage and the offset cancelling voltage as signal components of polarities opposite to each other, so that circuits following the correlated double sampling amplifier are not influenced by the offset voltage.Type: GrantFiled: July 23, 2002Date of Patent: August 31, 2004Assignees: Renesas Technology Corp., Hitachi Tohbu Semiconductor, Ltd.Inventors: Kouichi Yahagi, Masumi Kasahara, Hiroki Nakajima

Patent number: 6781107Abstract: In an imaging system having a semiconductor integrated circuit device, noise problems due to a large through-current in an output circuit resulting from the change-over of digital video data outputted from an AD conversion LSI are reduced by a technique involving encoding and code conversion. After AD conversion of an analog color video signal from an imaging element, a difference between codes of adjacent pixels is obtained in regard to the same color, and an output code of this difference is converted into a code with less change-over bits between the adjacent codes.Type: GrantFiled: February 25, 2002Date of Patent: August 24, 2004Assignees: Renesas Technology Corp., Hitachi ULSI Systems Co., Ltd., Hitachi Tohbu Semiconductor, Ltd.Inventors: Yasutoshi Aibara, Hiroki Nakajima, Eiki Imaizumi, Tatsuji Matsuura

Publication number: 20030209891Abstract: A structure of arranging an vehicle occupant protecting apparatus for an automotive vehicle, which can prevent a pillar garnish from scattering when an air bag installed in a front pillar portion is expanded, is provided. An air bag 16 is housed within a space formed by a front pillar main body 38 and a pillar garnish 40 in a front pillar portion 20. When the air bag 16 expands, the pillar garnish 40 is pressed by an expanding pressure of the air bag 16, so that an opening for expanding the air bag 16 is formed between the front pillar main body 38 and the pillar garnish 40, and the air bag 16 expands into a vehicle cabin through the opening. Since a non-expanding portion is formed at the air bag 16 and a hinge portion 46 is formed at the pillar garnish 40, the expanding pressure applied to the pillar garnish 40 when the air bag 16 expand is low, so that the pillar garnish 40 can be easily opened through the hinge portion 46.Type: ApplicationFiled: May 19, 2003Publication date: November 13, 2003Inventors: Yasushi Kubota, Masamichi Aono, Goro Takahashi, Takuya Ohtsuka, Minoru Shibata, Yutaka Nagai, Hiroyuki Tajima, Fumitake Kobayashi, Hiroki Nakajima, Chiharu Totani, Tadao Tanaka, Katsunori Noto

Patent number: 6530594Abstract: A jump-up stand is disposed below a folded air bag body and is also provided over a region from a position near a front side of a center pillar to the center pillar. The jump-up stand is formed from a plate material which is bent to have a substantially L-shaped cross sectional configuration and includes a wall portion extending toward an upper end of a center pillar garnish. Accordingly, when the air bag body expands, the air bag body expands toward the interior of a vehicle along the wall portion of the jump-up stand so as to prevent large load from acting on the upper end of the center pillar garnish.Type: GrantFiled: November 7, 2000Date of Patent: March 11, 2003Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hiroki Nakajima, Toshimitu Watanabe

Publication number: 20020179821Abstract: An AD-converted digital video data is encoded by a difference encoding method before it is outputted and such encoded digital video data is then outputted after it is converted to the gray code or to the predetermined code in which a fixed value is added. Thereby, the problems that power supply noise generated when the AD conversion circuit outputs a video data migrates into the CCD side via the power supply line (Vcc line and ground line) on the printed circuit board and that the power supply noise appears on the display image by migration into the input terminal side from the output circuit side via the power supply line and semiconductor substrate within the AD conversion LSI in the existing imaging system can be solved.Type: ApplicationFiled: February 25, 2002Publication date: December 5, 2002Applicant: Hitachi, Ltd.Inventors: Yasutoshi Aibara, Hiroki Nakajima, Eiki Imaizumi, Tatsuji Matsuura

Patent number: 6279941Abstract: Mounting portions of an air bag body are respectively nipped by positioning plates which are each fastened and fixed to a pillar inner panel by a weld nut and a bolt via the plates. Caulking portions are formed on the plates so that the mounting portions of the air bag device are in advance fixed between the plates. A convex portion is formed on the plate, and with the convex portion being engaged with a hole formed in the pillar inner panel, relative rotation of the plate and a vehicle body is prevented. As a result, rotation of the air bag body in a direction in which the mounting portions are fastened, which occurs during mounting of the air bag body to the vehicle body, can be prevented.Type: GrantFiled: August 27, 1998Date of Patent: August 28, 2001Assignees: Toyota-Jidosha Kabushiki Kaisha, Toyota Gosei Co., Ltd.Inventors: Hiroki Nakajima, Hiroshi Ishiyama, Toshinori Tanase, Yasuo Ochiai

Publication number: 20010000290Abstract: During a collision, an air bag causes deformation of a roof head lining as the air bag expands. A roof head lining deformation limiting structure restricts inward deformation of the roof head lining. Thus, the roof head lining is prevented from interfering with an interior equipment, e.g., a sun visor, thereby reducing breakage of the sun visor provided adjacent the roof head lining. The deformation limiting structure can take the form of an assist grip or a card holder. Also, the assist grip or the card holder can be mounted onto a member, e.g., a bracket, that plastically deforms upon being struck by the occupant's head during a collision, thereby absorbing a portion of the impact that would otherwise be transferred to the occupant.Type: ApplicationFiled: December 6, 2000Publication date: April 19, 2001Applicant: Toyota Jidosha Kabushiki KaishaInventors: Hiroki Nakajima, Toshimitu Watanabe
