  • Waterproof type photographing apparatus and package for lens-fitted photo film unit
    Patent number: 6483991
    Abstract: A tablet shaped catalyst is disposed on an upper portion inside a waterproof housing. The catalyst, which is comprised of palladium, accelerates a chemical reaction for combining hydrogen gas and oxygen gas. The catalyst begins accelerating the chemical reaction just after contacting with hydrogen gas. By disposing said catalyst on an upper position inside the waterproof housing, hydrogen gas, lighter than the air, is effectively removed. This chemical reaction causes to generate water, so it is preferable to provide a water absorbent by the catalyst.
