A dual clutch device includes a first piston applying a first clutch by a hydraulic pressure supplied into a first hydraulic pressure chamber and releasing the first clutch by a first spring, a second piston applying a second clutch by a hydraulic pressure supplied into a second hydraulic pressure chamber and releasing the second clutch by a second spring, a first supply line supplying a hydraulic pressure into the first hydraulic pressure chamber and a second hydraulic pressure canceling chamber, a second supply line supplying a hydraulic pressure into the second hydraulic pressure chamber and a first hydraulic pressure canceling chamber, a first valve allowing or cutting the supply of hydraulic pressure into the first hydraulic pressure chamber and the second hydraulic pressure canceling chamber, and a second valve allowing or cutting the supply of hydraulic pressure into the second hydraulic pressure chamber and the first hydraulic pressure canceling chamber.

Dual clutch device

A thermoacoustic heating device capable of effectively utilizing streaming, and including a prime mover in a first pipeline that forms a loop line, and a heating device in a second pipeline that forms another loop line. The first and second pipelines are connected to each other via a branch pipeline. A branch pipeline on the prime mover side and the second pipeline on the heating device side are positioned adjacent to each other, and a low-temperature side heat exchanger of the heating device is integrally formed with or held in contact with the branch pipeline on the prime mover side.

A free-piston type stirling engineincludes a power pistonwhich partitions the inside of a caseinto a work spaceand a bounce space, a displacer, a communication holeprovided in the power piston, a displacer rodextending from the displacerand passing through the communication hole, a first displacer supporting springelastically supporting the displacer rodat its proximal end, and a second displacer supporting springelastically supporting the displacer rodat its distal end. The power pistonand the displacerreciprocate along a central axis X of the casewith a phase difference therebetween by expansion and compression of a working gas in the work space, and bias forces of the first displacer supporting springand the second displacer supporting springrestrict tilting of the displacerand the displacer rodwith respect to the central axis X.

Free-piston type stirling engine

Planetary friction gear continuously variable transmission including an input shaft; a carrier; a planetary friction gear having a tapered roller at an inclined rotating shaft; an input-side support section, formed by notching a portion of an outer periphery of a carrier bottom section, rotatably supports an input side of the shaft; a sun roller provided on a same line as the shaft; a ring roller which is rotated by contacting a roller of the gear; an output shaft spaced from the ring roller; a loading section having a rolling body which presses the ring roller and the output shaft in an axial direction when a torque differential arises; and a transmission ring which contacts the tapered roller and allows the gear to spin.
