Abstract: A determining system includes an acquiring unit that acquires a color value of a target seal material, a storage unit that stores a color value of each of a plurality of candidate seal materials of different types, a color difference calculating unit that calculates a color difference between each of the candidate seal materials and the target seal material based on the color value of each of the candidate seal materials and the color value of the target seal material, a degree of coincidence calculating unit that calculates a degree of coincidence between each of the candidate seal materials and the target seal material based on the color difference between each of the candidate seal materials and the target seal material, and a determining unit that determines a type of the target seal material based on each of the degrees of coincidence calculated.

Abstract: Provided is a highly water repellent, air permeable, and liquid leakage resistant magnesium-air fuel cell that can quickly achieve a discharge reaction peak and can discharge a predetermined amount of current for a relatively long period of time. In a magnesium-air fuel cell, a cathode body includes: a first layer including a porous body formed by mixing a conductive carbon material and fluororesin; and a second layer including a porous body formed by mixing activated carbon and fluororesin, the second layer being joined to one surface of the first layer to be in contact with reaction liquid in the outer frame.

Abstract: In a vacuum gate valve, a seal member for sealing a gate opening part is bonded to an outer edge part of a planar seal plate that is disposed in such a manner that the planar seal plate is opposed to a valve seat surface of the gate opening part and comes into contact with the valve seat surface. The seal member includes a vacuum seal part that is located on a side farther from the gate opening part and maintains the sealability of the gate opening part when the gate opening part is closed, and also includes a radical seal part that is located on a side closer to the gate opening part and that prevents the seal member from being affected by a treatment gas in the gate opening part when the gate opening part is closed. The vacuum seal part is made of a rubber elastic body, and the radical seal part is configured by providing a radical resistant body that is provided with an excellent radical resistance on the rubber elastic body.
