摘要:
Filters having a high accuracy, small pressure loss, and long filtration life compared with conventional filters are provided. The filters are composed of non-woven fibrous agglomerates and are constructed in such a way that at least two layers of a non-woven fibrous agglomerate of a pre-filtration layer and a precision filtration layer are disposed therein; the pre-filtration layer is constructed in such a way that the diameter of the fibers in the pre-filtration layer becomes gradually smaller toward the direction of filtration; and at least 10% by weight of the fibers in the precision filtration layer are fibers having a diameter smaller than that of the fibers having a smallest diameter in the pre-filtration layer.
摘要:
A mechanical key (17) is housed in a mechanical key storing part (15) offset to one side within a key body (1), a bulge (18a) of a key head (18) being housed in an extension part (16a) of an aperture (16), a bridging part (19) that forms a holder linking hole (20) being formed so as to protrude at just the center of the rear end surface of the key body (1) thereby establishing left-to-right symmetry and avoiding an unbalanced appearance. Because the key head (18) of the mechanical key (17) can be formed so that the lever length from the key center axis line is large, it is possible to lighten the key rotational force when the mechanical key is used.

摘要:
Disclosed is a laminated non-woven fabric of a multi-layer structure comprising a layer of a composite, spun bond non-woven fabric composed of long fibers containing a low melting point resin component and a high melting point resin component, and a layer of a non-woven fabric of melt-blow ultrafine mixed fibers comprising low melting point ultrafine fibers and high melting point ultrafine fibers both of the fibers have an average fiber diameter of 10 .mu.m or less, both of the layers are laminated, and fibers in each of the non-woven fabrics and both of the layers are heat-melt adhered with each other. The laminated non-woven fabric has a good hand feeling and a high peeling strength of adjacent layers, but has no rough feeling.
