  • Patent number: 11865794
    Abstract: The present invention provides a prepreg that has high impact resistance despite being an all-carbon-fiber FRP (CFRP), the prepreg moreover enabling a molding time to be set to five minutes or less and making it possible to reduce molding costs. This prepreg is obtained by impregnating carbon fiber with a matrix resin comprising a mixture of a thermoplastic resin, a thermosetting resin, and a curing agent, wherein: the thermoplastic resin is a phenoxy resin; the thermosetting resin is a urethane acrylate resin; the thermoplastic resin and the thermosetting resin are compounded in a mass ratio of 15:85-35:65 (thermoplastic resin/thermosetting resin); and the curing agent causes cross-linking to occur due to a radical polymerization reaction, and is formed so as to include first and second peroxides having mutually different initiation temperatures, initiation of the second peroxide starting at a temperature at which termination of the first peroxide occurs.

  • Patent number: 11791174
    Abstract: A semiconductor manufacturing apparatus includes a chuck stage, a scrubber nozzle, a scrubber nozzle scan mechanism, a stage rotation mechanism, and a holding stage including a holding fluid nozzle and a top plate, the top plate having one main surface facing an opposite surface of a wafer, and the holding fluid nozzle being disposed adjacent to a center rather than a periphery portion of the top plate. A holding fluid discharged from the holding fluid nozzle is caused to flow through an area between the opposite surface of the wafer and the one main surface of the top plate to produce holding force, and the holding force causes the opposite surface to hold pressure applied to a processing surface of the wafer by a scrubbing fluid discharged from the scrubber nozzle.

  • Patent number: 11772041
    Abstract: A composite amine absorbent according to the present invention is an absorbent for absorbing CO2 or H2S, or both of CO2 and H2S in a gas. The absorbent is obtained by dissolving (1) a linear monoamine, (2) a diamine, and (3) propylene glycol alkyl ether, for example, represented by the following chemical formula (I) in water. In the composite amine absorbent, the components complexly interact, and the synergistic effect thereof provides good absorbability of CO2 or H2S, or both of CO2 and H2S and good releasability of CO2 or H2S absorbed during regeneration of the absorbent. Furthermore, the amount of water vapor in a reboiler 26 used during regeneration of the absorbent in a CO2 recovery unit 12 can be reduced.
