Abstract: A writing tool such as a ball pen or the like including an openable decorative article at a shaft end comprises a shaft member serving as a casing for the writing tool, a core vertically displaceably received in the shaft member, an actuation member connected to the core, a movable member adapted to move when the core is downwardly displaced at the time of practical use of the writing tool, and a support member for supporting the decorative article. The actuation member includes a fixing piece and an actuation piece protruded outside of the shaft member. When an user displaces the actuation piece in the downward direction with his finger for practical use of the writing tool, an assembly of the movable member and the support member is displaced in the same direction, whereby the decorative article is expanded via a flange integrated with the support member as if petals of a flower are opened. At this time, a butterfly-shaped accessory fixedly mounted on the central part of the support member appears.

Abstract: In this invention, two connecting devices are provided in a burner device to accommodate liquefied gas cylinders/fuel tanks having different mounting cap configurations. The invention also includes a piezoelectric ignition device as part of the burner device for igniting gas provided by the liquefied gas cylinder/fuel tank.

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: This invention relates a handy burner device comprising an ignition device as well as a combustion device, whereby fuel gas blown out of a nozzle can be automatically ignited by operation of the ignition device, and a valve device capable of suitably controlling a flow rate of liquefied gas fuel, whereby adjustment of combustion flame can be suitably effected according to the object of use, an intake quantity of air necessary for combustion can also be adjusted and in addition, thermal power of the burner can be controlled.
