Abstract: A uniformity waveform for a tire (T) and a rotational phase of a load drum (4) are measured with a load drum (4) pressed against the tire (T). In a waveform of the frequency domain acquired by frequency conversion of the uniformity waveform, the amplitude and phase for a component of an integer multiple of the rotational frequency of the load drum (4) are found and stored as a correction parameter. A corrected tire (T) uniformity waveform is calculated by subtracting from the uniformity waveform a correction waveform calculated on the basis of the correction parameter, the correction waveform being the one in the rotational phase range of the load drum (4) during tire measurement.

Abstract: At least one of ground contact pressure, shear stress and amount of skidding is measured at a measurement point on a tread surface of a tire. A sensor is arranged on a road surface and the measurement point is made to contact the sensor while the tire rotates. An initial position of the tire is set, where the measurement point is at a previously-set reference position and the tire is at a running start position on the road surface. The tire is made to run from the initial position to obtain a rotation angle difference ? between a tire rotation angle until the rotation axis of the tire passes over the arrangement position of the sensor and a tire rotation angle until the measurement point contacts the road surface. The tire is set at the initial position and rotated by ? without changing the running start position of the tire.

Abstract: A mixing valve assembly 42 is communicated with a dedicated tank 51D, storing therein a compatibilizer D, via an inlet valve 43 and is also communicated with dedicated tanks 51A-51C via three injection valves, the tanks storing therein auxiliaries A-C respectively. A chemical formulation is prepared by selectively injecting any one(s) of four chemical agents into the mixing valve assembly 42 by way of on-off control of the inlet valve 43 and the injection valves and blending together the injected chemical agents. Then, the chemical formulation is pumped into SCF by a high-pressure pump 45 such that the SCF and the chemical formulation are mixed together to form a process fluid. Thus, the number of components of a high-pressure portion can be reduced to achieve a cost reduction of an apparatus. Furthermore, a pipe line for pumping the chemical agents is simplified.

Abstract: After subjected to a developing process, a rinsing process and a replacing process in this order in a developing unit 10A, 10B, a substrate W wet with an anti-drying solution is wet-transported to a supercritical drying unit 20 by a primary transport robot 30. The supercritical drying unit 20 performs a high-pressure drying process (supercritical drying process) in a dedicated manner. Accordingly, by virtue of the presence of the anti-drying solution, the substrate W is effectively prevented from becoming air-dry during the transportation of the substrate W.

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.
