Abstract: A resin film has through holes formed to extend through the thickness of the resin film. The through holes are pillar-shaped. An average density of the through holes is 1×106 to 1×1012 holes/cm2. An average diameter of the through holes is 1 to 310 nm. A degree of variability of the diameter of the through holes is 30% or less, the degree of variability of the diameter of the through holes obtained by dividing a standard deviation of the diameter of the through holes by the average diameter of the through holes and multiplying the resulting value by 100.

Abstract: The present invention provides an air-permeable filter capable of maintaining excellent air permeation performance without being clogged even in an environment involving exposure to an oil, oil mist, or ink. The present invention relates to an air-permeable filter including a porous membrane having a surface coated with an oil-repellent agent, the filter being characterized in that a sliding angle of 20 ?l of hexadecane or pentadecane on the surface of the filter is 60° or less.

Abstract: A slicer is provided which slices a slicing subject with a uniform thickness and can be used in a sanitized manner. The slicer includes a resin-made frame which supports both ends of a slicing blade, a resin-made movable support plate attached to the frame so as to be able to ascend and descend, first reinforcing members buried in the frame, a second reinforcing member buried at one end of the movable support member in a width direction, and a third reinforcing member buried at the other end. The first reinforcing members, the second reinforcing member, and the third reinforcing member absorb bending stress acting on the slicer.

Abstract: A waterproof sound transmission structure of the present disclosure includes: a wall separating a first space from a second space where water can be present, the wall being provided with a sound transmission port for transmission of sound between the first and second spaces; and a waterproof sound-permeable membrane placed to cover the sound transmission port, the waterproof sound-permeable membrane being adapted to permit transmission of sound between the first and second spaces and being further adapted to prevent ingress of water from the second space into the first space through the sound transmission port. The first space is sealed when the second space is filled with water, the sealed first space having a volume of 300 mm3 or less. The waterproof sound transmission structure of the present disclosure has higher levels of both waterproofness and sound permeability than conventional waterproof sound transmission structures.

Abstract: An acoustic resistor for use in an audio device includes a resin film having air permeability in a thickness direction of the resin film, and the resin film is a non-porous film having through holes formed to extend straight through the resin film in the thickness direction. This acoustic resistor is used in an audio device including: a transducing part that performs conversion between sound and an electrical signal and that includes an acoustic element; a housing enclosing the transducing part and having at least one opening; and a passage for gas that is present inside the housing and communicates with the opening and in which the acoustic element is placed. The acoustic resistor is placed between the opening and the acoustic element in the passage. The variation in properties of the acoustic resistor of the present disclosure can be made smaller than that of conventional acoustic resistors.

Abstract: The polymer film of the present invention has through holes extending from one principal surface of the polymer film to the other principal surface of the polymer film. The through holes are straight holes having a central axis extending straight, and have a shape in which the area of a cross-section perpendicular to the direction of the central axis increases from the one principal surface of the polymer film toward the other principal surface. This polymer film has passages in its thickness direction, has an unconventional structure, and can be used in various applications, such as in a waterproof sound-permeable membrane, in a waterproof gas-permeable membrane, and in a suction sheet. The ratio a/b of the opening diameter a of the through holes at the one principal surface to the opening diameter b of the through holes at the other principal surface is 80% or is less than 80%.
