摘要:
A vacuum arc deposition device having electrode switching means comprising two or more electrodes consisting of vacuum arc vapor evaporation source materials and a substrate to which films are formed by means of vacuum arc vapor deposition, each of the electrodes and the substrate being contained in a vacuum chamber capable of introducing a reactive gas, wherein the electrodes are connected to arc discharging DC power supplies by way of polarity switching means so that each of the electrodes functions as a cathode and an anode alternately. Films, in particular, of insulative property can stably be vapor deposited on a substrate for a long period of time continuously.

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). The torque canceller (5) is equipped with a motor (30) for the spindle shaft, which imparts a torque for cancelling the impact of the rotational friction torque (My1) to the spindle shaft (20).

To effectively suppress a shift of a rotating axis of an upper chuck with respect to a rotating axis of a lower chuck due to a separating force. A tire testing device (1) includes: vertical frames (30a, 30b) which are supported by a lower frame (20); a beam (40) which bridges between the vertical frames (30a, 30b) and is movable in the vertical direction; an upper chuck (45) which is attached to the center of the beam (40), the center corresponding to the center of the beam in the longitudinal direction; and a lower chuck (25) which is attached to the lower frame. When viewed from the vertical direction, a rotating axis of an upper rotating member (47) is positioned at the center of a straight line formed by connecting supporting points where each of the vertical frames (30a, 30b) support the beam (40).
摘要:
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.
摘要:
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.
