  • Patent number: 9398709
    Abstract: A portable electronic apparatus has a water-resistant structure in which a cover covers a surface of an opening formed in a casing of the portable electronic apparatus. The portable electronic apparatus includes a mounting unit that has an outer peripheral surface to which frame-shaped packing that encompasses the opening is attached, and is formed on any one among the casing and the cover; and a groove that is formed on an outer peripheral surface of the mounting unit, and holds the frame-shaped packing therein enabling a surface of the frame-shaped packing to be brought into pressure contact with any one among the casing and the cover to which the mounting is not formed. The mounting unit has a side and a corner, and is of a shape that encompasses the opening, and the groove has a shape at the corner different from that along the side.

  • Patent number: 7904259
    Abstract: A waterproof testing device tests waterproof performance of a waterproof component. The testing device includes an input unit, a storing unit and a determining unit. The input unit inputs permeability of one or more test objects with waterproof components disposed thereon and an air flow rate that is a volume of gas passing through the test object per unit time for each test object. The storing unit stores, in a data pair, the permeability and the air flow rate of each test object input by the input unit. The determining unit determines a range of permeability in which no water leakage occurs in the waterproof component based on a range of air flow rate in which no water leakage occurs and the stored permeability and air flow rate.
