摘要： A sliding device 1 is constituted of a swash plate 3 including a first sliding surface 3A and a semispherical shoe 4 sliding with the swash plate 3. The swash plate 3 is constituted of a base material 3B of high strength brass containing Mn and Si, and very small granular Mn—Si compounds 6 are exposed on an inside of the base material 3B and on the first sliding surface 3A (surface of the base material 3B). The above described swash plate 3 increases in exposure amount of the Mn—Si compounds 6 exposed on the first sliding surface 3A by applying etching to the base material 3B after cutting the base material 3B. The sliding device 1 is favorable in seizure resistance and has a low manufacturing cost as compared with conventional sliding devices.

摘要： Multiple embodiments of ferromagnetic shape memory alloy (FSMA) based torque actuators are described. These torque actuators include a magnetic trigger and an FSMA member, which when actuated by the magnetic trigger, produces a torque for rotating a member. Examples of magnetic triggers include hybrid magnetic triggers having at least one electromagnet and at least one permanent magnet. The FSMA member can be configured as a coil (or plate) spring and can be fabricated of a true FSMA alloy (i.e., an alloy that exhibits both ferromagnetic and shape memory properties) or of an FSMA composite that includes a ferromagnetic portion and an SMA portion. Several embodiments include a central orifice in which the FSMA member and an axial rod configured to rotate when actuated are disposed; the magnetic trigger system is disposed about the periphery of the orifice.

摘要： A membrane actuator includes a magnetically actuatable membrane and a magnetic trigger. The membrane includes a shape memory alloy (SMA), and the magnetic trigger is configured to induce a martensitic transformation in the SMA, to produce a larger force than would be achievable with non-SMA-based materials. Such a membrane actuator can be beneficially incorporated into a wide variety of devices, including fluid pumps, shock absorbing systems, and synthetic jet producing devices for use in an aircraft. The membrane/diaphragm can be formed from a ferromagnetic SMA, or a ferromagnetic material can be coupled with an SMA such that the SMA and the ferromagnetic material move together. A hybrid magnetic trigger, including a permanent magnet and an electromagnet, is preferably used for the magnetic trigger, as hybrid magnetic triggers are easy to control, and produce larger magnetic gradients than permanent magnets or electromagnets alone.

摘要： A crankshaft and an mounting hole have two main circular arc parts on the same circle; and two connecting parts for connecting the adjacent main circular arc parts, and have a cross-sectional shape in which the connecting parts facing each other are substantially parallel. The connecting parts of the mounting hole are formed in the shape of a large circular arc which projects inward. The torque of the crankshaft is transmitted to the mounting hole in a state where the connecting parts of the crankshaft and the connecting parts of the mounting hole which are formed in the shape of a large circular arc come into line contact with each other; therefore, the value of any local stress generated in the mounting hole can be reduced.
