  • Publication number: 20090084774
    Abstract: A method for joining dissimilar materials by superposing, one over the other, a first material and a second material having a larger intrinsic resistance than that of the first material, heating the second material and pressing the first material and the second material against each other, which comprises conducting induction heating only from the side of the first material upon heating the second material to thereby heat the second material at the portions in contact with the first material.

  • Publication number: 20080135532
    Abstract: The forming of a heated spot (10) by using a laser beam irradiated to a brittle substrate along a predetermined scribing line (S) and the ejecting of a cooling medium, after interruption of irradiation of laser beam, to impinge on the spot to thereby form a cooled spot (20) constitute a unit operation to be repeated. The cooled spot overlapping the heated spot (10) that has a longitudinal center line (b) crossing the scribing line (S) at a right angle serves to restore thermal equilibrium in and around the spots while forming unit cracks (n) continued one from another to form a linear crack (E,U) perpendicular to the brittle substrate surface.

  • Patent number: 7191806
    Abstract: The opening of an oil container 11 for storing oil 12 is sealed airtight with a cover member 32. A one-sided-bag-shaped fluid dynamic pressure bearing 10 is seated on an O-ring 25 and fixed airtight onto the upper surface of a bearing seating 30. Inanexhaust position with the distal end portion of an injection tube 36 positioned away from an oil level, the inside of the oil container 11 is evacuated by a vacuum pump 22 through a suction/exhaust passage including a suction/exhaust through-hole 17, thus turning the inside of the one-sided-bag-shaped fluid dynamic pressure bearing (10) into a vacuum. In this state, a control device drives a moving device to raise the oil container 11 to an injection position and releases the suction/exhaust passage to the atmosphere. This causes the oil 12 to be injected into the one-sided-bag-shaped fluid dynamic pressure bearing 10 through an oil injection passage including the injection tube 36.

  • Patent number: 6628798
    Abstract: In a vibration actuator using a magnetic circuit device (14), a supporting arrangement (23) elastically supports the magnetic circuit device. A coil (17) is inserted into a magnetic gap (15) of the magnetic circuit device and is supported by a vibration plate (19). The vibration actuator has a first operation mode in which the magnetic circuit device mainly vibrates to transmit vibration through the vibration plate to the outside, a second vibration mode in which the coil mainly vibrates to produce a buzzer sound through the vibration plate, and a third vibration mode in which the magnetic circuit device and the coil mainly vibrate to produce a sound corresponding to a speech through the vibration plate.

  • Patent number: 6575633
    Abstract: In a hydraulic bearing motor, by means of dynamic pressure generating grooves provided on a thrust shaft with a larger diameter not only on the end face thereof but also on the shaft surface thereof, pressures generated in oil when rotating a shaft body are made to be applied not only in the axial direction but also in the radial direction with high magnitude. This can provide the hydraulic bearing motor as being capable of satisfying features of exhibiting small NRRO, and vibration and shock resistance even with a thinned hydraulic bearing motor.

  • Patent number: 6552456
    Abstract: A hydraulic dynamic pressure bearing motor has a rotational shaft mounted to undergo rotation about a rotational axis and having a shaft section and a flange section. A sleeve has a cavity for receiving the rotational shaft. A cover member is disposed over an open end of the sleeve cavity. A hydraulic dynamic pressure bearing includes minute radial and thrust clearances disposed between outer surface portions of the shaft and flange sections of the rotational shaft and inner surface portions of the sleeve and the cover member. A lubricating fluid is disposed in the minute radial and thrust clearances. The minute radial and thrust clearances are dimensioned so that during a non-rotational state of the rotational shaft, the flange section of the rotational shaft contacts preselected inner surface portions of the sleeve and the cover member while the shaft section of the rotational shaft does not contact any portion of the sleeve and an inner peripheral surface of the cover member.
