  • Patent number: 11413227
    Abstract: The invention provides a cosmetic having strong resistance to contact with water, clothing, fingers, and abrasion with little decline (post-contact) in the cosmetic effects such as UV blocking protection as well as excellent feel on use. The cosmetic contains: (A) plate-shaped powder, (B) 6-40% by mass UV absorber, and (C) cationic surfactant.

  • Publication number: 20220159791
    Abstract: This high-frequency hardening apparatus is provided with: an induction heating coil which has a U-shaped part that sandwiches a turbine blade, a pair of linear parts, and a connection part connecting the U-shaped part and the linear parts; a temperature detection unit which detects, in a non-contact manner, temperature around the induction heating coil; a moving mechanism which relatively moves the turbine blade and the induction heating coil in the direction of blade height; an electrical current supply unit which supplies a high-frequency electrical current to the induction heating coil; and a control device which has an electrical current control unit that, on the basis of a detection value provided by the temperature detection unit, controls the magnitude of the high-frequency electrical current supplied from the electrical current supply unit such that the detection value will not exceed a predetermined temperature.

  • Patent number: 11187103
    Abstract: A steam turbine power generation facility and an operation method of such facility not only overcome the thermal elongation difference between a revolving body and a stationary body of a turbine so as to shorten start-up time but also suppress the efficiency of such facility from deterioration. The steam turbine power generation facility includes a boiler to generate steam; a high-pressure turbine into which the steam generated by the boiler flows; an intermediate-pressure turbine into which steam worked at the high-pressure turbine flows; and a low-pressure turbine into which steam worked at the intermediate-pressure turbine flows, in which the high-pressure turbine and the intermediate-pressure turbine are respectively provided with a heating section which is formed by communicating through the high-pressure turbine and the intermediate-pressure turbine, and further includes a pipe to make the steam worked at the high-pressure turbine flow into the heating section.
