Abstract: This external stimulus application system is structured so as to comprise: an external stimulus unit that applies an external stimulus to a target area of a user's body; a detection unit that detects changes in a detected area of the user's body during an action of the user; a control unit that causes the external stimulus unit to produce a stimulus if a detected value detected by the detection unit satisfies a prescribed condition; and a storage unit that stores the detected value.

Abstract: A gas turbine steam cooled system has a high temperature portion 8 outlet steam temperature maintained to a predetermined value without a cooling steam pressure becoming lower than the pressure in the gas turbine cylinder. Steam coming from an intermediate pressure superheater 10 of a waste heat recovery boiler 2 is led into the high temperature portion 8 of the gas turbine for cooling thereof. The temperature of the cooling steam at the outlet of the high temperature portion 8 is detected by a high temperature portion outlet steam temperature detector 15, and a signal thereof is sent a lower value selector 19 via a temperature controller 11. Pressure in the gas turbine cylinder is detected by a gas turbine cylinder pressure detector 17, and pressure of the cooling steam at the high temperature portion 8 outlet is detected by a high temperature portion outlet steam pressure detector 16. A differential signal thereof is sent to a pressure controller 18.
