Abstract: The heat insulation sheet is provided with a fixing layer that is arranged between a base material and a carbon sheet. The fixing layer is made of a pressure-sensitive adhesive. The base material has flexibility. The carbon sheet is made by rolling expanded graphite and has a thickness from twenty-five micrometers to one hundred micrometers. In the sheet material, activated carbon is arranged opposite to the fixing layer side of the heat insulation sheet, and a surface material is arranged on a surface of the activated carbon. The fixing layer can be constituted in such a manner that a hot-melt adhesive is arranged in a reticulate manner.

Abstract: A carbon formed body covers an outlet of a dryer. The carbon formed body is formed into a disc made from isotropic high-density graphite, and elongated holes are provided along a spiral line so as to penetrate through the disc. Hence, the opening areas of the carbon formed body can be extended while preventing reduction in the strength of the carbon formed body. Therefore, when the dryer that includes the carbon formed body attached to the outlet is in use, a smaller pressure loss is caused at the carbon formed body and the heat accumulation phenomenon is prevented. Furthermore, breakage of carbon formed bodies is inhibited at the time of manufacturing.

Abstract: A gum massaging tool includes a handle portion which accommodates electric or mechanical members and in which a selector switch is provided in an exposed manner; a fixed shaft portion that is fixed to the handle portion so as to extend from one end of the handle portion and is heated according to an operation of the selector switch; a gum contact portion that is rotatable around a distal end portion of the fixed shaft portion and that includes a carbon body which receives heat from the fixed shaft portion and transfers the heat to a gum contacting surface; and a supporting portion that is rotatably engaged with and supports the gum contact portion and is detachably attached to the handle portion.
