Abstract: An image forming apparatus includes a first rotatable member, a second rotatable member, an air nozzle, and a pipe. The pipe includes a portion provided in a range overlapping with the first rotatable member and making one reciprocation or more in a case that when a direction crossing a feeding direction of a recording material fed in a nip is a widthwise direction of the first rotatable member, the pipe is viewed in a direction perpendicular to the widthwise direction.

Abstract: In one embodiment, a thermal energy storage power plant includes a thermal accumulator to accumulate thermal energy and heat a thermal medium with the thermal energy, and a steam generator to generate steam using the thermal medium. The plant further includes a first path to convey the thermal medium from the accumulator to the generator, and a second path to convey the thermal medium from the generator to the accumulator. The plant further includes an auxiliary module provided on the first path, and a bypass path to convey the thermal medium flowing through the second path to the auxiliary module by bypassing the accumulator, wherein the auxiliary module is supplied with a first thermal medium from the accumulator via the first path, supplied with a second thermal medium from the second path via the bypass path, and supplies a third thermal medium to the generator via the first path.

Abstract: In one embodiment, a heat storage power generation system includes a heater to heat first fluid, and a heat storage to be heated by the first fluid, and heat second fluid with heat stored in the heat storage. The system further includes a generator to generate electric power by using the second fluid, and one or more first path switchers provided on a first path through which the first fluid is circulated between the heater and heat storage. The system further includes one or more second path switchers provided on a second path through which the second fluid is circulated between the heat storage and generator, one or more third path switchers provided on a third path through which at least one of the first and second fluids is circulated between the heater and generator, and a switching controller to control the first, second and third path switchers.

Abstract: In one embodiment, a heat storage power generation system includes a heater to heat first fluid, and a heat storage to be heated by the first fluid, and heat second fluid with heat stored in the heat storage. The system further includes a generator to generate electric power by using the second fluid, a heating controller to control heating of the first fluid by the heater, and a power generation controller to control power generation performed by the generator. The heating controller controls the heating of the first fluid, based on two or more limit values among a first limit value related to an amount of energy consumption by the heater, a second limit value related to temperature of the first fluid, a third limit value related to internal temperature of the heat storage, and a fourth limit value related to a change rate of the internal temperature.

Abstract: In one embodiment, a plant control apparatus controls a power plant. The apparatus includes a gas turbine, an exhaust heat recovery boiler to generate main steam, a first steam turbine driven by first steam, and a first valve to supply the first steam to the first steam turbine. The plant further includes a reheater to generate reheat steam, a second steam turbine driven by second steam, and second and third valves to supply the second steam to the second steam turbine. The apparatus includes an acquisition module to acquire a setting value of total output of the first and second steam turbines, and a control module to adjust the total output to the setting value by controlling opening degrees of the first, second and third valves. The control module controls the second and third valves to different opening degrees when adjusting the total output to the setting value.

Abstract: An epoxy-modified vinyl copolymer (A) includes 0.1 to 95 parts by mass of an epoxy group-containing vinyl monomer and 5 to 99.9 parts by mass of one or more vinyl monomers selected from aromatic vinyl monomers, vinyl cyanide monomers and additional vinyl monomers copolymerizable with these monomers, the copolymer having a weight average molecular weight Mw of 50,000 to 300,000 and an epoxy equivalent of 150 to 143,000 g/eq. A thermoplastic resin composition includes the epoxy-modified vinyl copolymer (A) and a thermoplastic resin (C) such as a thermoplastic polyester resin (B). A shaped article includes the thermoplastic resin.
