Abstract: An inertial filter is placed in a fluid flow path and equipped with a particle classifying sheet having a plurality of particle classifying holes uniformly arranged. The particle classifying sheet has a sheet area larger than a fluid passage area at a site where the sheet is placed. A part of the sheet is provided in the form of a partition wall dividing the fluid flow path in two sections in a fluid passage direction to allow for classification of particles.

Abstract: The transfer apparatus includes a light source, a transmission type image display device in which a liquid crystal layer is held between two sets of substrates and polarizing plates and a photosensitive recording medium. The light source, the image display device and the photosensitive recording medium are arranged in series along a direction in which light from the light source advances and the image display device and the photosensitive recording medium are arranged in a non-contact state. A display image transmitted from the transmission type image display device is transferred to the photosensitive recording medium. A distance between the image display device and the photosensitive recording medium and a sum total of thicknesses of the substrate and the polarizing plate at least on a side of the photosensitive recording medium in the image display device are set in accordance with a definition of the display image.

Abstract: A magnetic tape cassette in which critical parts subject to wear are coated with a hard coating such as an ultraviolet-cured resin. Among other effects, the generation of rubbed-off powder is reduced, thereby reducing the amount of data drop-out. Also, the case of the cassette is protected from damage.
