Abstract: The massage machine includes a chair main body that includes: a seat part on which a person to be treated is seated, a backrest part, which is provided at a back part of the seat part, and on which the person to be treated leans, and a footrest which is provided at a front part of the seat part and supports leg parts of the person to be treated; guide rails and which are provided at the chair main body; and a first massage part and a second massage part which are configured to respectively move in the height direction along the guide rails. The first massage part moves at least from a position corresponding to the backrest part to a position corresponding to the seat part, and the second massage part moves at least from a position corresponding to the footrest to the position corresponding to the seat part.

Abstract: A method of brazing a metal work is disclosed, in which the work is heated to at least the softening temperature of resin and coated with a suspension constituted of a mixture of a flux and a binder, after which the work is brazed by being heated and dried. As a result, the binder (resin) attached to the surface of the work is softened and increases in stickiness. Even if foreign matter becomes attached to the work surface, therefore, the binder causes the flux to be firmly attached to (coupled with) the work surface together with the foreign matter. Thus, the flux can be securely coated (attached) on the work surface. The temperature of the work is not lower than the evaporation temperature of water. Even if oil becomes attached to the work surface, therefore, the water in the suspension is evaporated before it can be repelled by the oil, thus making it possible to prevent the flux from being repelled along with the water. In this way, the flux can be securely coated (attached) on the work surface.
