Abstract: A force sense imparting operation device that imparts a force sense in accordance with a load acting on an actuation device. The device includes an operation member, a displacement detector, a load detector, a force sense generator that imparts a force sense to an operator who operates the operation member, a current controller that performs an actual control and a preliminary control, the actual control increasing the force sense imparted by the force sense generator by increasing an excitation current in response to an increase in the load, the preliminary control supplying the excitation current to an excitation coil prior to the actual control, the excitation current supplied by the preliminary control being set to a preliminary current value lower than the excitation current supplied to the excitation coil under the actual control, and a current supplying portion that supplies the excitation current to the excitation coil.

Abstract: Provided is a rim width adjustment mechanism for the tire testing machine, capable of being reduced in the number of components and miniaturized. The rim width adjustment mechanism includes a lower spindle for rotatably supporting the tire about a vertical axis through the lower rim, a plunger disposed in a through hole of the lower spindle to be raisable and lowerable to the lower spindle and having an upper end connectable to the upper spindle, and a rim width adjustment cylinder for adjusting the rim width by changing the protrusion length of the plunger beyond the lower spindle. The lower spindle is coupled to a cylinder side wall of the rim-width adjustment cylinder, thereby allowing a downward load applied to the lower spindle to be supported by the cylinder sidewall.

Abstract: A hydraulic rotary machine configured to reduce sliding resistance of a reciprocating piston and to suppress a reduction in volumetric efficiency corresponding to an amount of leakage of hydraulic oil. A piston pump includes a rotor shaft, a cylinder block, a piston head, a piston rod, a retainer, a swash plate, and a tilt regulation mechanism. When the tilt regulation mechanism rocks the swash plate, the amount of discharge from the piston pump is variably changed. The retainer which rotates with both the piston head and the piston rod is supported by a retainer bush provided to the rotor shaft. The retainer sphere section of the retainer and the retainer bush sphere section of the retainer bush have spherical shapes having the same curvature. During the regulation of tilt, the retainer rocks while the retainer bush sphere section is in sliding contact with the retainer bush.

Abstract: A CAES generator includes a plurality of motors, a plurality of compressors, a pressure accumulator, an expander, a generator, an electric-motor inverter that changes a rotation speed of each of the motors, a feed command receiver that receives input power as a feed command value before feeding the input power, and a controller. The controller includes a compressor number calculation unit that calculates a maximum number of motors that are allowed to be driven at a rating based on the feed command value, and a compressor drive control unit that drives at the rating, the motors, the number of which is the maximum number calculated by the compressor number calculation unit.

Abstract: A metal base plate material includes trip-shaped first regions each having a plurality of first ridges arranged substantially parallel to each other and at substantially equal intervals such that an angle of intersection with a longitudinal direction is greater than or equal to 10° and less than or equal to 25°. Strip-shaped second regions each have a plurality of second ridges arranged substantially parallel to each other and at substantially equal intervals and angled to face the plurality of the first ridges in a crosswise direction. The first regions and second regions are separated by a gap regions therebetween, at substantially equal intervals. First ends on a downstream side of the plurality of the first ridges and second ends on a downstream side of the plurality of the second ridges are positioned differently from each other in the longitudinal directions.
