  • Publication number: 20240077826
    Abstract: A chute is located between a transfer roller and a fuser in a direction crossing both a first direction along a drum axis direction and a second direction crossing the first direction. The chute causes a sheet having passed through a transfer nip to be directed toward a fixing nip. The chute is movable in the second direction between a first position and a second position shifted from the first position toward one side in the second direction. The chute located at the second position is farther away from an imaginary plane passing through the nips than the chute located at the first position. A reciprocating mechanism is located on an other side of the chute in the second direction. The reciprocating mechanism reciprocates by drive force from the drive source and presses the chute to move between the first position and the second position.

  • Patent number: 10526013
    Abstract: A parking assist apparatus includes: a distance obtaining portion that obtains a movement distance from a current position of a vehicle to a parking target position; a vehicle speed calculating portion that calculates a target vehicle speed with a lapse of time until the vehicle reaches the parking target position, based on the movement distance, and a vehicle speed and acceleration and deceleration which are set in advance; a position calculating portion that calculates a movement target position of the vehicle in accordance with the time until the vehicle reaches the parking target position, based on the target vehicle speed with the lapse of time; and a controller that controls a vehicle running state such that the vehicle is moved to the movement target position at the target vehicle speed.

  • Patent number: 10471991
    Abstract: A parking assistance device that performs parking assistance when parking a vehicle in a parking area, includes: a speed calculation unit that calculates a first target vehicle speed for each control cycle indicating a cycle for calculating a target vehicle speed set as a target of a vehicle speed of the vehicle based on a target distance for the vehicle to move to a target position and the control cycle, the target position being included in the parking area; and a control unit that controls the vehicle such that the vehicle speed becomes the calculated first target vehicle speed for each control cycle.

  • Publication number: 20130072767
    Abstract: For providing a living organism information detection system that is capable of extracting, with high precision and inexpensive structure, living organism information including a heartbeat signal, the living organism information system is configured to include a vibration detection unit acquiring simultaneously vibrations of multiple pieces of living organism information, an amplification unit having a first filter and a second filter with a longer time constant than the first filter, the first and second filters being inputted with vibrations of two pieces of living organism information, the amplification unit amplifying the acquired vibration signal so as to be in inverse proportion to the output signal of the first filter or the output signal of the second filter, whichever is smaller, and a discrimination unit discriminating between the two pieces of living organism information by comparing the amplitude of the amplified vibration signal and a threshold.
