Abstract: A second tank for accommodating a sample is disposed within a first tank. A heater for heating gas is provided inside the second tank. A heater controller controls the heater such that temperature of gas becomes a set temperature. A heat conducting member is disposed such that one end of the heat conducting member is positioned in the gas inside the first or second tank and the other end is positioned in the humidifying water contained in the humidifier. The heat conducting member is made of material having higher thermal conductivity than that of gas inside the first or second tank.

Abstract: A second tank for accommodating a sample is disposed within a first tank. A heater for heating gas is provided inside the second tank. A heater controller controls the heater such that temperature of gas becomes a set temperature. A guide portion which guides condensed dew such that the condensed dew can flow downward and reach the outer surface of the second tank is provided on the inner surface of the first tank.

Abstract: A portable device for welding a heat weldable tube has a main body case, a first electrode supported on an end part of the main body case, a movable member arranged opposite to the end part of the main body case, a second electrode arranged on the movable member substantially opposite to the first electrode, a manipulation member for displacing the movable member forwardly and rearwardly with respect to the end part of the main body case, a first elastic member returning the manipulation member to a predetermined position when the manipulation member has been opened, and a second elastic member providing elasticity in a direction of movement of the movable member when the movable member moves toward the end part of the main body case by the manipulation member.
