摘要： In a medical device that measures a condition of a living body, a first recess is formed on the exterior (first and second surfaces) of its casing. An anti-slip member is attached to the inside of the first recess. Moreover, another recess (second recess) is provided inside the first recess. The second recess is formed such that an end of the second recess protrudes from the anti-slip member when the anti-slip member is attached to the inside of the first recess. In the case where a display screen that displays a measurement result is provided on the casing, it is preferable that the first and second surfaces are adjacent to a third surface on which the display screen is provided.

摘要： A substrate processing method which can reduce the number of particles to be left on each substrate is provided. In the substrate processing method, substrates W to be processed are dried, by using a fluid heated by a heating apparatus having one or more heating mechanisms. The substrate processing method comprises a first step of supplying a mixed fluid containing a gas and a processing liquid and heated by the heating apparatus, into a processing chamber in which the substrates to be processed are placed, and a second step of supplying the heated gas into the processing chamber. The output of at least one of the heating mechanisms is kept at a preset constant value for a period of time during which a predetermined time passes after the start of the first step. In the second step, the output of the heating mechanism is determined under a feed back control.
