Abstract: The present invention is directed to rapid positioning assistance for a mechanical section of a transcranial magnetic stimulation system. This transcranial magnetic stimulation system comprises a coil section 11 that is in contact with or in the vicinity of the head of the subject, and a mechanical section 30 that supports the coil section 11. The mechanical section 30 includes a plurality of adjustment mechanisms that adjust position of a plurality of movable members, and determines position and attitude of the coil section 11 by adjustment using the plurality of adjustment mechanisms. Receiving means receives desired change for at least one of position and attitude of the coil section 11. Guidance means provides guidance of an adjustment procedure for at least one of the plurality of adjustment mechanisms so as to realize adjustment corresponding to the desired change that has been received.

Abstract: Provided is an oxygen concentration device which, as an oxygen concentration device having a reduced difference in flow rates of gas which flows through a pressure equalization valve of a pressure equalization path during a purge step and a pressure equalization step, is provided at at least one end side of the pressure equalization valve with a pressure control member having a difference in pressure loss due to the direction of gas flow so that pressure loss of the gas which flows through the pressure equalization path in one direction becomes nearly equal to that of the gas which flows therethrough in the opposite direction.
