  • Publication number: 20240085252
    Abstract: [Problem] To Provide a fabric-like sensor in which an output signal can be improved when in use and damage or fracture of a sensor element hardly occurs, and a fabric-like sensor device using it. Solution In a fabric-like sensor S having a fabric base material 1 and a line-shaped sensor element 2, at least one line-shaped cavity portion 11 is provided inside the fabric base material 1, and at least a part of the cavity portion 11 is composed of a raw fabric at least a part of the cavity portion has no elasticity in a line direction of the cavity portion 11, and further the line-shaped sensor element 2 is arranged in a state of not being substantially constrained or fixed in at least one of cavity portions in a fabric 1.

  • Publication number: 20240068884
    Abstract: A thermosensitive part sensing temperature; a temperature sensor for measurement provided in the unit and measuring temperature by contacting the unit with a body to be measured; a temperature detecting part detecting, from when the unit contacts the body, the time when the sensor senses a difference from an initial temperature of the sensor, and a measured temperature of the sensor at that time, and detecting, from when the difference is sensed, a time after a certain length of time and a measured temperature of the sensor at that time; an estimating part estimating, from the time when the difference is sensed and a time after a certain length of time, the time when the thermosensitive part contacts the body, and the measured temperature at that time; and a heat conduction analyzing part estimating the measured temperature based on output information from the temperature detecting part and the estimating part.

  • Patent number: 6168216
    Abstract: The present vehicle door latch device comprises a latch unit for keeping a door in a closed state, and a powered closing unit for supplying the power for fully closing the door, to the latch unit. A motor of the closing unit is connected to a wire lever of the latch unit through a power wire, and an opening lever of the latch unit is connected to a canceling lever of the closing unit through a safety wire. The latch unit has a one-motion door opening mechanism. An inner lever connected to an inside opening handle is engageable with the opening lever. A switch which detects the rotational position of a latch of the latch unit is arranged in such a position as not to be overlapped onto the wire lever.

  • Patent number: 5921612
    Abstract: An initially opening device for a vehicle sliding door comprises an output member rotated by a motor, a winch lever rotated from a stand-by position to an initial-open position, a connecting lever for connecting the output member to the winch lever, a press member provided in the sliding door and connected to the winch lever, a ratchet lever connected to a latch unit provided at rear portion of the door for engaging a striker fixed to a vehicle body, and a contact surface formed in the ratchet lever and brought into contact with the winch lever for rotating the ratchet lever when the winch lever is rotated toward the initial-open position. The press member is brought into contact with the vehicle body to move the rear portion of the sliding door in an initial opening direction when the winch lever is displaced from the stand-by position to the initial-open position.

  • Patent number: 5913563
    Abstract: A powered sliding device for a sliding door comprises a wire drum rotated by a motor, a wire cable connecting the wire drum and the sliding door, a clutch mechanism provided between the wire drum and the motor. The clutch mechanism has a first coupling state for opening the door, a second coupling state for closing the door, and an uncoupling state. The wire drum has a cylindrical shape having a substantially closed end and an opposite open end, and an inner space formed inside thereof. The clutch mechanism is substantially provided within the inner space. The clutch mechanism is displaced into the first coupling state when the motor rotates in a given direction and displaced into the second coupling state when the motor rotates in a direction opposite to the given direction.

  • Patent number: 5867940
    Abstract: A powered sliding device for sliding a vehicle door comprises a base plate, a wire drum rotatably mounted on the base plate by a drum shaft and rotated by a motor, a wire cable for pulling the door in an opening direction or in a closing direction when the wire drum rotates, a tension shaft slidably mounted on the base plate in a given direction and having a tension roller, a movable member slidably mounted on the base plate in a direction perpendicular to the given direction, and a coupling member having one end rotatably connected to the tension shaft and the other end rotatably connected to the movable member. The given direction coincides with a radial direction of the drum shaft. Each side of a contact portion of the wire cable relatively to the tension roller extends straight toward the wire drum.
