  • Patent number: 9879921
    Abstract: A heat exchanger includes fins that are arranged in a direction orthogonal to a direction in which air flows and a heat transfer pipe that extends through the fins and that is bonded and fixed to the fins when the heat transfer pipe is radially expanded by a pipe-expanding method. Tall projections and short projections are provided on an inner surface of the heat transfer pipe. The tall projections are arranged in a circumferential direction and extend in an axial direction of the heat transfer pipe. The short projections are arranged between the tall projections and extend in the axial direction. Opposing side surfaces of the tall and short projections after the expansion of the heat transfer pipe are so inclined that when extensions are drawn from the side surfaces, the extensions cross each other in an inner region of the heat transfer pipe.

  • Patent number: 8657593
    Abstract: The present invention is aimed at providing a sintered magnet production system that can prevent the influences of a leaking magnetic field in an orienting process. A sintered magnet production system according to the present invention has a filling means 11 for filling an alloy powder into a filling/sintering container, a sintering means 13 for sintering the alloy powder, and an orienting means 12 with an air-core coil for producing a magnetic field for orienting the alloy powder in the filling/sintering container after the filling process and before the sintering process, the axis of the air-core coil being displaced from a straight line connecting the filling means 11 and the sintering means 13. The magnetic field leaking from the orienting means 12 is strongest on the extended line of the axis of the air-core coil and relatively weak in the direction perpendicular to the extended line.

  • Patent number: 8488344
    Abstract: In a conventional electrical power conversion apparatus, a control microprocessor performs a control for eliminating or curbing a beat phenomenon, so that a control delay occurs because computing time is required in the control microprocessor. Because of the control delay, it is not possible to obtain an effect of sufficiently reducing a current ripple and torque pulsation. In addition, in an electric train in which a frequency of an AC power source is changed over while the train is running, it is required for a method of detecting a ripple component by a band-pass filter that a plurality of band-pass filters are provided and then the changeover is performed depending on the power source frequency, resulting in difficulties to take countermeasures.

  • Patent number: 8395037
    Abstract: Fullerene inhibited the decrease in cell proliferation ability of chondrocytes which is observed when cultured chondrocytes are treated with a cartilage degenerating factor (IL-1? or H2O2). Fullerene inhibited production of cartilage matrix-degrading enzymes (matrix metalloprotease (MMP)-1, 3 and 13) which is induced in cultured chondrocytes by cartilage degenerating factors. Fullerene restored the decrease in cartilage matrix (proteoglycan) synthesizing ability which is observed in treating cultured chondrocytes with cartilage degenerating factors. In an analysis using an osteoarthritis rabbit model, the progress of cartilage degeneration was reduced by administering fullerene. Moreover, the dynamic friction coefficient was decreased by adding fullerene to synovial fluid.

  • Publication number: 20110070118
    Abstract: A mold which is inexpensive and easy to process and does not embrittle. Also provided is a process by which a sintered. NdFeB magnet can be produced using the mold without suffering bending or deformation. At least part (e.g., a bottom plate) of the mold is made of a carbon material. Carbon materials have lower friction with a sinter during sintering than metals. The mold hence enables a sintered NdFeB magnet to be produced without suffering the bending or deformation caused by friction due to sintering shrinkage. Carbon materials are inexpensive and easy to process. The mold does not embrittle even when repeatedly used. Such effects can be significantly produced when a carbon material is used as the bottom plate, on which the load of the sinter is imposed during sintering.
