  • Publication number: 20110000292
    Abstract: Provided is a tire testing machine capable of measuring a force generated in a tire with high precision. The tire testing machine includes a spindle shaft (20) for holding a tire (T), a housing (22) for rotatably supporting the spindle shaft (20) through a rolling bearing (25), a running device (10) having a surface rotated by rotational driving and imparting a rotational force to a tire contacting the surface, and a measurement device (4) which is provided in the housing (22) and measures a force and moment generated in the spindle shaft (20) when the tire (T) is running. Furthermore, the tire testing machine includes a torque canceller (5) for preventing the spindle shaft (20) from such an impact that rotational friction torque (My1) generated by rotational friction, which is received by the spindle shaft (20) in the housing when the spindle shaft (20) rotates, is imparted onto the shaft (20).

  • Publication number: 20090308156
    Abstract: A tire testing machine according to the present invention, which can measure both uniformity and dynamic balance of a tire T, comprises a spindle for driving the tire T to rotate about a vertical axis, a spindle housing which supports the spindle rotatably, and a rotating drum rotatable about an axis parallel to an axis of the spindle and movable toward and away from the tire T. The spindle housing is fixed to a base through a piezoelectric sensor so that it can bear a pressing force provided from the rotating drum. The piezoelectric sensor is disposed within a plane including the axis of the spindle and perpendicular to the pressing force. With this structure, dynamic balance of the tire can be measured accurately and easily.

  • Patent number: 7520938
    Abstract: An object is subjected to high-pressure processing by bringing at least a high-pressure fluid into contact with the object under pressure in a high-pressure processing chamber, and then the high-pressure processing chamber is depressurized while the temperature in the chamber is controlled to be maintained above a temperature achieved by an adiabatic expansion, the adiabatic expansion starting from the pressure and temperature at the end of the high-pressure processing step. To control in such a way, the temperature in the high-pressure processing chamber is controlled so as to suppress or recover a temperature descent caused by an adiabatic expansion during the depressurizing step. This solves a problem in which the temperature is decreased to the vapor-liquid phase coexistence region or a region in which a solid is deposited.

  • Patent number: 7513265
    Abstract: Disclosed is a high pressure processing method for subjecting a processing object to a high pressure processing using a high pressure fluid. In this method, the high pressure fluid is brought into collision with the surface of the processing object placed in a high pressure processing chamber, and then distributed along the surface of the processing object in an outward direction beyond the processing object.

  • Patent number: 7335596
    Abstract: Cu-based interconnections are fabricated in a semiconductor device by depositing a thin film of Cu or Cu alloy on a dielectric film by sputtering, the dielectric film having trenches and/or via holes at least one groove and being arranged on or above a substrate, and carrying out high temperature and high pressure treatment to thereby embed the Cu or Cu alloy into the trenches and/or via holes, in which the sputtering is carried out at a substrate temperature of ?20° C. to 0° C. using, as a sputtering gas, a gaseous mixture containing hydrogen gas and an inert gas in a ratio in percentage of 5:95 to 20:80.

  • Patent number: 6916735
    Abstract: A temporary support layer 2 is formed on a semiconductor substrate 1, and the temporary support layer 2 is provided with a hole 4 that reaches the semiconductor substrate 1. The hole 4 is filled in with a conductor material 5, and by pressurizing the conductor material 5, the conductor material 5 and the semiconductor substrate 1 are pressure-bonded. Thereby, an aerial wiring structure whose bonding strength is improved and that has excellent self-sustainability can be obtained.

  • Publication number: 20040226588
    Abstract: The corrosion resistance against hydrogen fluoride of a cleaning apparatus using a high-pressure fluid is markedly improved by making at least the surfaces of portions in contact with hydrogen fluoride out of a Fe-based alloy or Ni-based alloy containing a predetermined amount of Cr. Even when cleaning is carried out with the high-pressure fluid containing hydrogen fluoride by this cleaning apparatus, the apparatus has excellent durability and is free from the eluation of a metal which causes the deterioration of a micro-structure as an object to be cleaned.
