    摘要: A structural member is produced using starting powder consisting of composite particulates each containing AlN grain within its surface covered by an Al layer of a single crystal structure, and Al alloy particulates of a single crystal structure, and then by sintering the Al layers of the composite particulates with the Al alloy particulates. The Al layers and the Al alloy particulates of the single crystal structure have no dislocation fault, crystal grain boundary. etc., produced therein, and for this reason, they have a low chemical activity. Therefore, the Al layers and the like have a characteristic that they are extremely difficult to oxidize. This ensures that the Al layers and the Al alloy particulates can be reliably sintered to achieve the densification of the resulting structural member.

    摘要: A wire-and-pulley drive link mechanism such as a robot hand, comprising a base, a linkage connected to said base by a first joint and having a first link and a second link connected by a second joint like fingers. The base carries motors for individual links. A wire-and-pulley drive system is provided such that said linkage moves relative to said base and said first link moves relative to said second link moves when driven by said motors. The wire is made of amorphous material and a coil is wound on each of the wires to detect stress or tensile force by sensing a change of magnetic permeability generated when the wire is subject to external force. A control system having a joint servo is provided and determines a manipulated variable to be supplied to the motor based on at least the detected stress and a servo gain.

    摘要: In a method for operating a gas compressor which compresses gas whose supply conditions change and which is equipped with an intake-flow regulating mechanism, a limit pressure ratio that defines the operational upper limit of the pressure ratio relative to the intake flow rate of the gas compressor or the degree of opening of the intake-flow regulating mechanism to prevent surging in the gas compressor is corrected by multiplying a reference limit pressure ratio calculated from the design conditions of the gas compressor by a first correction factor calculated depending on a detected operating-state value of the gas compressor.

    摘要: A bistable minivalve includes a movable component, an actuator that is electrostatically, magnetically, or mechanically coupled to the movable component for controllably switching the movable component between open and closed states, and a casing providing structural support. The movable component has an actuation surface [300] movably positioned in the valve conduit and a bistable element attached to the actuation surface providing mechanical stability to the open and closed states of the movable component. The bistable element may be realized as a pair of elastic buckling beams [302, 304] attached at their midpoints to opposite sides of the actuation surface. Optionally, there may also be elastic support beams [306, 308] attached at their endpoints to the actuation surface and attached at their midpoints to the elastic buckling beams.
