A gas sensor, disposed projecting from a wiring member serving as a mounting target and including a first wire and a second wire, the gas sensor detecting a gas that produces water in a case that the gas is combusted by being supplied with a voltage from the first wire and the second wire and measuring a resistance value using the first wire and the second wire, the gas sensor including a resistor holding a catalyst that facilitates combustion of the gas, a first electrode terminal connected between one end of the resistor and the first wire, and a second electrode terminal connected between another end of the resistor and the second wire, and the first electrode terminal and the second electrode terminal are fixed to each other and form a water vapor diffusion cavity.

Gas sensor

A roller-type automatic foil exchanger for supplying a foil beneath a window in a flange of a surface of a vacuum container of an electron beam irradiator includes a foil feed roller having foil wound thereon and a foil take-up reel for winding foil thereon. The foil is supported on a foil holder beneath the window and between the flange and the foil holder. A winding motor rotates the take-up reel to wind foil thereon and to unwind foil from the foil feed roller. A plurality of clamper members are provided to clamp the foil holder to the flange with the foil therebetween.

Automatic exchanger of an electron beam irradiator for window foil

An automatic hydraulic clamping mechanism for a window foil holder of an electron beam irradiator includes a foil holder suspended below a flange at the bottom of a vacuum container. A foil is mounted on the foil holder and hydraulic hanging cylinders are provided at each corner of the holder and are driven to raise the foil holder such that it remains parallel to the flange. Once the foil is raised to be in contact with the flange a plurality of hydraulic clamping cylinders are energized to clamp the foil holder in place.
