摘要： Provided are: a carbon fiber bundle which has a large value of single-fiber fineness and excellent productivity and which, despite this, contains few interlaced single fibers therein and has excellent spreadability; and precursor fibers which are suitable for use in producing the carbon fiber bundle. The precursor fibers are a carbon-fiber-precursor acrylic fiber bundle which comprises a polyacrylonitrile copolymer comprising 95-99 mol % acrylonitrile units and 1-5 mol % hydroxyalkyl (meth)acrylate units and which has a single-fiber fineness of 1.5-5.0 dtex. In the acrylic fiber bundle, the cross-section of each single fiber which is perpendicular to the fiber axis has a shape that has a roundness of 0.9 or less. The roundness is a value determined using equation (1) where S and L are the cross-sectional area and the circumferential length, respectively, of a single fiber which are obtained by examining, with an SEM, the cross-section of the single fiber which is perpendicular to the fiber axis and analyzing the obtained image. Roundness=4pS/L2  (1)

In the metal plate for heat exchange of the present invention, a recess part 2 having a depth of 5 μm or more and 10% or less of a plate thickness of the metal plate is formed. A crevasse part 7 is formed at least at a bottom corner 6 of the recess part 2. The crevasse part 7 is formed by cutting away the bottom corner 6 of the recess part 2 in the thickness direction. An angle θ formed by one cut-away surface and the other cut-away surface is 90 degrees or less. In addition, the crevasse part 7 is formed by cutting away a crystal grain 9. The recess part 2 is formed on the surface of the metal plate 1 by pressing a working part 14 formed on a surface of a working roll 12 against the surface of the metal plate 1 being carried.

摘要： There is disclosed an acrylic fiber (a) consisting of an acrylonitrile polymer comprising an acrylonitrile unit in at least 80 wt % and less than 95 wt %, (b) having a monofilament dry strength of 2.5 to 4.0 cN/dtex, (c) having a monofilament dry elongation of 35 to 50%, and (d) forming a crack with a length of 20 &mgr;m or more in its tension rupture lateral surface along the filament axis direction when rupturing the monofilament in a tension test. The fiber has even orientation in its surface and inside; is significantly improved in dry strength, dry elongation and dyeability; and exhibits wool-like hand feeling. It is, therefore, quite suitable as a synthetic fiber for various applications such as a garment material, e.g., a sweater and a home furnishing material such as a pile.

An original plate material for a heat-exchanging plate is a flat plate material made of titanium on the surface of which convex parts and concave parts are formed, and the heat-exchanging plate is fabricated by press working the original plate material. The convex parts and the concave parts are formed in a manner such that the shape parameter defined by (Rz×L/P) is 12 μm or less, where Rz (μm) denotes the height of the convex parts, L (μm) denotes the width of the concave parts, and P (μm) denotes the pitch between neighboring convex parts.
