摘要:
A radio communication device performs baseband processing by subjecting a received signal to an AD conversion at a predetermined sampling frequency and converting a digital signal resulting from the AD conversion into a baseband signal by frequency conversion. The device includes a frequency converting unit configured to convert the resulting digital signal into a complex baseband signal. The device further includes a waveform shaping unit configured to subject the baseband signal to waveform shaping, and a down-sampling unit configured to subject the baseband signal to sample discrete reduction.

A hot isostatic pressing device according to the present invention includes an inner casing, an outer casing, and a heating means which are provided inside a high-pressure container. The device further includes a first cooling means for forcedly circulating pressure medium gas in such a manner that pressure medium gas guided upwardly between the inner casing and the outer casing is guided to the outside of the outer casing through an upper part of the outer casing, cooled while being guided downwardly along an inner circumferential surface of the high-pressure container, and then returned to between the inner casing and the outer casing through a lower part of the outer casing; and a second cooling means for guiding pressure medium gas within a hot zone formed inside the inner casing to the outside of the hot zone, cooling the pressure medium gas guided to the outside by merging it with the pressure medium gas forcedly circulated by the first cooling means, and returning the cooled pressure medium gas into the hot zone. According to such a structure, a high cooling efficiency can be attained while maintaining the hot zone in a thermally uniform condition.

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.

An intake gasket to be inserted between a cylinder head and a manifold, comprising an intermediate rib member 1 with a three-layer structure formed from a thin metal plate 11 and rubber layers 12 and 12 provided on both sides of the thin metal plate, metal plates 2 and 2 disposed on both sides of the intermediate rib member 1, and elastic metal substrates 3 and 3 disposed on both sides of the metal plates 2 and 2, the intermediate rib member 1 comprising a first rib 15 formed around the periphery thereof and a second rib 14 formed around the periphery of a fluid passage hole, wherein a space is formed from the rib of the intermediate rib member 1 and the metal plates 2 and 2 disposed on both sides of the intermediate rib member 1. The intake gasket can shut out heat from the cylinder head so as to make transmission of heat to the manifold difficult.

When the hatch of a substrate washing chamber 5 is opened to receive a substrate, certain valves are closed, and a valve is opened, supply CO2 to purge the substrate washing chamber 5 to and exclude air. When the hatch is closed, another valve is opened to vent substrate washing chamber 5 so that the CO2 expels any gas and unwanted air from the substrate washing chamber 5 and the conduits. Thereafter, super critical CO2 is used to wash the substrate and clean the circulation line. The flow of supercritical CO2 is sent to the substrate washing chamber 5. After flowing through the circulation line, including a circulation channel 11, it passes through a bypass channel 12 to a decompressor 7. Any chemicals or organic substances left in the circulation line are continuously sent to a separation/recover bath 8 together with the flow.
