  • Patent number: 11370298
    Abstract: A work vehicle includes front and rear wheels, a transmission case and a power transmission device. The power transmission device is housed in the transmission case and is configured to transmit driving power from an engine to driving wheels. The power transmission device has a front wheel driving shaft and a four-wheel drive clutch. The front wheel driving shaft is arranged in a lower inside portion of the transmission case and is configured to transmit the driving power to the front wheels. The four-wheel drive clutch is arranged above the front wheel driving shaft, and is configured to switch between a two-wheel drive state in which the driving power is transmitted to the rear wheels, and a four-wheel drive state in which the driving power is transmitted to both the front wheels and the rear wheels via the front wheel driving shaft.

  • Patent number: 9944292
    Abstract: A working vehicle includes: a power transmission device which selects a four-wheel drive state and a two-wheel drive state; a hydraulic continuously variable transmission device which includes a trunnion arm displaceable to a forward movement position, a neutral position, and a backward movement position; a pedaling operation detection unit which detects a pedaling operation for a brake pedal; and a control unit which performs a process of moving the trunnion arm to the neutral position by controlling an actuator when the pedaling operation detection unit detects the pedaling operation and which sets the operation speed of the actuator to be slow in the four-wheel drive state during the process compared to the two-wheel drive state.

  • Patent number: 9522244
    Abstract: A brain cooling apparatus is provided that can circulate a fluid between a containing unit of a brain cooling device and the brain cooling apparatus while maintaining an appropriate pressure of the fluid in the containing unit, and a brain cooling device suitable thereto also is provided. A control device circulates a physiological saline solution between a storage tank and a cuff by driving a first pump in a direction in which the physiological saline solution flows toward the cuff, and driving a second pump in a direction in which the physiological saline solution flows toward the storage tank. In this state, the control device adjusts the rotation speed of at least the second pump, so that the pressure of the physiological saline solution in the cuff becomes a preset target pressure.

  • Patent number: 6812467
    Abstract: An apparatus for reading images of a photographic film disposed on an image reading optical path, with a light source (31a) for emitting visible light and infrared light into the image reading optical path to irradiate the photographic film, and a zoom lens unit (32a) for the visible light and infrared light irradiating the photographic film. A visible light sensor and an infrared light sensor are disposed separately for detecting a visible image based on the visible light from the zoom lens unit, and for detecting an infrared image based on the infrared light from the zoom lens unit, respectively. A focal position varying transparent element (FT) is provided for shifting a focal position of the zoom lens unit along an optical axis. The transparent element is movable to and from a position between the zoom lens unit and infrared light sensor to correct variations in the focal position occurring with variations in magnification of the zoom lens unit.

  • Patent number: 6275248
    Abstract: A vacuum fluorescent printer including a print head (60) having luminous blocks (32, 33, 34) each having a plurality of luminous elements arranged in a main scanning direction for irradiating a photosensitive material with light released from phosphorous objects to which electrons are applied based on a drive signal, thereby forming dots on the photosensitive material. A further luminous block (32b) is provided which is spaced from the luminous blocks (32a, 33, 34) in the sub-scanning direction and used for printing a particular color among the three colors (R, G, B). Each dot of the particular color is formed by light from a plurality of luminous blocks (32a, 32b). A printer controller (7c) is provided for generating a pulsed drive signal as the drive signal. The number of pulses in the drive signal is determined based on a density value of the image data, and the slower a moving speed is in the sub-scanning direction, to the larger pulse width the drive signal is set.
