  • TRACTOR
    Publication number: 20240155962
    Abstract: A tractor includes a hydraulic lifting and lowering driver to lift and lower a three-point linkage, a load detector to swing according to a traction load of an implement, and a mechanical linkage to transmit a swing amount of the load detector to the lifting and lowering driver. The mechanical linkage includes a first linkage on one side in a right-left direction of a vehicle body frame and interlockingly linked with the load detector, a second linkage on the other side in the right-left direction of the vehicle body frame and interlockingly linked with the lifting and lowering driver, and an operation cable interlockingly linking the first linkage and the second linkage.

  • Method of manufacturing barium titanate and electronic component of barium titanate
    Patent number: 9796631
    Abstract: A method of manufacturing barium titanate powder by dispersing, in a solvent such as ethanol, barium titanate. Then, the barium titanate is separated from the slurry by evaporating the solvent while pressurizing the slurry in a pressure container. Then, the separated barium titanate is subjected to a heat treatment, thereby producing the barium titanate powder.

  • Method of producing barium titanate
    Patent number: 9745204
    Abstract: A method of producing barium titanate that includes making a slurry by dispersing barium titanate powder in a solvent such as ethanol. Then, in a high-pressure vessel, substituting supercritical fluid including carbon dioxide gas, for example, for the solvent in the slurry. Then, separating the barium titanate powder from the supercritical fluid by gasifying the supercritical fluid. Then, performing a heat treatment on the separated barium titanate powders to produce the barium titanate.
