Abstract: A gas combustion type dryer is provided wherein a liquefied gas is ignited by electric discharge and combusted to forcibly blow out heated air by a fan, while eliminating adverse effects of remaining heat after the stop of fan operation and maintaining the gas pressure constant. A temperature controller is provided together with a combustor within a blowing barrel of a dryer main body, and a pressure regulator is provided together with a liquefied gas tank within a handle. The pressure regulator is coupled to the combustor with the temperature controller interposed therebetween.

Abstract: A thermal fumigator is disclosed which vaporizes a drug in order to fumigate a space. The drug is vaporized by heat generated when the vapors of a volatile fuel come in contact with a metal catalyst. The fumigator includes a fuel container, a metal catalyst and a compressed mat, impregnated with a drug, which are held at fixed distances from each other for maximum efficiency.

Abstract: A catalyst combustion curling device comprises a handle interiorly provided with a liquefied gas tank; a heating barrel mounted on the handle to serve as a curling iron member or a member for mounting the teeth of a comb; a combustion valve provided on the liquefied gas tank; a catalytic member for combusting a liquefied gas from the combustion valve within the heating barrel; and an ignition device for the liquefied gas and an operator on the side of the handle to open and close the combustion valve.
