摘要:
A power generation apparatus includes an expander and a power transmission shaft that extracts a rotational driving force generated by the expander to the exterior of a housing of the expander. The housing of the expander contains a driving unit of the expander within a space enclosed by a partition wall of the housing. The power transmission shaft includes a magnetic coupling, divided between the interior and exterior of the housing of the expander through the partition wall. The rotational driving force extracted via the magnetic coupling is used as auxiliary power that supplements the power of a driving source provided separately from the expander when driving a rotating machine using the power of the driving source. A clutch mechanism and a speed variator are provided in a power transmission path that transmits the rotational driving force extracted by the power transmission shaft to the driving source.
摘要:
The present invention provides a method for processing a substrate in which crystal defects occurring according to ion implantation can be prevented from being integrated to form defects such as dislocation or large vacancies in the manufacture of a SIMOX substrate by implanting oxygen atom to a Si base by ion implantation and reacting it with Si to form a buried oxide film. The annealing after ion implantation is performed under a gas atmosphere pressurized to, for example, about 100 MPa. In the pressurized state, a structure having a smaller volume is thermodynamically more stable, and a behavior as increases crystal distortion is arrested in the annealing. Thus, crystal defects can be laid in uniformly dispersed state, vacancies can be also extinguished, and a Si base of good quality suitable for manufacture of ULSI in which defects such as dislocation are reduced can be provided.

In a high temperature/high pressure vessel for treating a workpiece placed in the interior of the vessel at a high temperature and a high pressure wherein piano wire is wound under tension round an outer periphery of a cylindrical body to apply a compressive residual stress to the cylindrical body and axial openings of the cylindrical body are tightly closed with upper and lower lids so that the lids can be disengaged from the openings, the cylindrical body is constituted as a two-layer cylindrical body comprising an inner cylinder and an outer cylinder which is fitted on the inner cylinder through plural spacers arranged along an outer periphery surface of the inner cylinder, allowing cooling water flow paths to be formed each between adjacent such spacers so as to extend from one end side to an opposite end side of the tow-layer cylindrical body. In this high temperature/high pressure vessel, vessel packings can be cooled effectively, the piano wire is not wet with cooling water, and the internal space of the vessel can be utilized effectively.

摘要:
A cooling device for a high pressure vessel which is simple in construction and high in safety and has a high cooling faculty without the necessity of changing a design of the high pressure vessel. The cooling device has a cylindrical cooling medium jacket having a cooling medium passage formed therein. The cooling medium jacket is removably disposed in a high pressure chamber of the high pressure vessel between the high pressure vessel and an insulation mantle surrounding a heater in the high pressure chamber such that a gap may be left between the high pressure vessel and the cooling medium jacket. The cooling medium jacket has a passage hole formed therein for establishing communication between the gap and the high pressure chamber to allow pressure medium to be introduced into the gap. The cooling device further includes a pressure medium supply means provided in the gap for introducing therethrough pressure medium different from the pressure medium for the HIP process to support THE cooling medium jacket with a hydraulic pressure of the different pressure medium.

摘要:
A high-temperature high-pressure processing method for semiconductor wafers in which semiconductor wafers are charged into a pressure vessel to carry out processing under the gas atmosphere of high-temperature high-pressure, wherein the high-temperature high-pressure processing is carried out in the state that an anti-oxidizing body (an oxygen getter member) formed of a material having properties in which oxygen is apt to diffuse into interior is arranged within the pressure vessel whereby the anti-oxidizing body takes oxygen into the pressure vessel, thus preventing oxygen within the pressure vessel from being reduced to oxidize the surfaces of the semiconductor wafers in the high-temperature high-pressure processing.
