  • Patent number: 6938715
    Abstract: If a control device determines that a collision during a vehicle run has been detected on the basis of a combination of an output signal of a sensor and a vehicle speed signal, an inflator is actuated so as to inflate and deploy an air bag body disposed in an apron upper member. When inflated and deployed, the air bag body raises a longitudinal-direction central portion of a hood. At this time, the longitudinal-direction central portion of the hood bends with a depression serving as an origin of bending.

  • Publication number: 20050088874
    Abstract: A semiconductor memory encompasses a memory cell array having a spare memory cell array; a holding circuit having banks of fuses, configured to read and hold fuse information; a decision circuit configured to determine which address of memory cell is to be replaced with which spare memory cell based on the fuse information from the holding circuit; and a holding-controller configured to control reading and holding of the fuse information in the holding circuit by receiving a power supply completion signal and a refresh signal. The holding circuit rereads the fuse information when the reread signal is generated, after the holding circuit reads once the fuse information by receiving the power supplying completion signal.

  • Patent number: 6397688
    Abstract: A seating load detecting device in which a lower arm for supporting a seat cushion and a seat back is coupled with an upper rail by a front bracket and a rear bracket. A distortion gage is attached to the bracket. The bracket comprises a curved portion of a U-shape or V-shape. The lower arm and the upper rail are coupled to each other with the direction orthogonal to two opposing legs of the curved portion being vertical. The distortion gage has a total of four distortion detecting elements G11 to G22 distributed in a matrix distribution, two attached in the front and back directional plane of the legs and two attached in the width directional plane of the legs. Due to the Wheatstone bridge connection line of these elements, high gain of a seating load detection voltage e with respect to the amount in change of the vertical load Fv can be obtained.

  • Patent number: 6398258
    Abstract: An air bag apparatus for a passenger seat has reduced deploying speed and reduces the impact of the air bag on an occupant moving forward at the time of a crash of a vehicle. A gas generator is disposed in a case of the air bag apparatus, extending in a fore-to-aft direction relative to the vehicle. The gas generator case contains a cylindrical inflator extending in the fore-to-aft direction. An air bag is disposed in the apparatus case, folded in a predetermined manner. An inner bag for controlling gas flow is disposed in the air bag, folded in a predetermined manner. An auxiliary inner bag is sewed to an outside surface of a bag of the inner bag. When the inner bag is inflated and deployed, the bag of the inner bag presses a portion of the air bag against the windshield, and the auxiliary inner bag presses another portion of the air bag against the instrument panel.

  • Patent number: 6371513
    Abstract: A side airbag is housed together with an inflator containing a high pressure gas as a module in a door-side side portion of a seat. The side airbag is deployed into a space between the door and an occupant sitting in the seat, on the basis of an instruction signal from an airbag control device. An occupant sensor is disposed at a position that is located in an upper portion of a seatback of the seat and shifted from a center of the seatback with respect to directions of a width thereof toward a vehicle body center. By using the occupant sensor, it is determined whether an occupant is present at a seat of a vehicle, excluding a case where an occupant having a constitution smaller than a predetermined constitution is leaning against the side vehicle body portion. The airbag control device permits operation of the side airbag if presence of an occupant is detected by the occupant sensor. The control device prohibits operation of the side airbag if absence of an occupant is detected by the occupant sensor.

  • Patent number: 6367837
    Abstract: A seated-state detection sensor is disposed in a seat portion of a seat cushion of a passenger seat. The seated-state detection sensor is divided into three parts, that is, a first seated-state detection sensor, a second seated-state detection sensor and a third seated-state detection sensor, which are arranged in this order from the rear side of the vehicle. The first seated-state detection sensor and the second seated-state detection sensor are designed to determine whether or not there is a passenger seated. The second seated-state detection sensor and the third seated-state detection sensor are designed to detect forward displacement of the passenger.

  • Patent number: 6356200
    Abstract: A sensor attaching portion of an upper rail and a sensor attaching portion of a cushion frame are provided with a sensor attaching plate having a sensor disposed thereon. The upper rail and the seat cushion frame are connected with a bracket at a position facing the sensor attaching plate. When the passenger sits on the seat, the seat cushion frame moves down and a bent portion of the bracket is pressed and deformed downwards. At this time, the center in the vertical direction of the sensor attaching plate is bent outward in the lateral direction of the seat. The sensor serves to detect the generated deformation.

  • Patent number: 6186538
    Abstract: An air bag control system for passenger seat has a seated-state detection sensor provided in a seat, a proximity sensor that detects an object near an air bag apparatus, and an impact sensor that detects a deceleration at the time of an impact. If there is no detection made by the proximity sensor for a predetermined length of time after the seated-state detection sensor detects the seating of an occupant, a control device keeps the air bag apparatus in an operable state after elapse of the predetermined length of time. If there is no detection made by the proximity sensor for the predetermined length of time after the seated-state detection sensor makes detection, the control device ignores an on-state of the proximity sensor or a signal from the proximity sensor, and keeps the air bag apparatus in the operable state.

  • Patent number: 6031246
    Abstract: A simulation method capable of efficiently evaluating reliability of gate oxide films formed on the elements within short periods of time to evaluate characteristics of a semiconductor device made up of elements of any size and any number. In a semiconductor device having transistors formed thereon, a pattern for evaluating characteristics of a semiconductor device characterized in that gate area portions, gate bird's-beak portions and LOCOS bird's-beak portions, are factors affecting the insulation breakdown of the gate oxide film, are rendered to be variable, so that the shapes of these portions can be handled as independent parameters.
