The core material contains 0.5-1.6% of Mn, 0.10-0.50% of Cu, 0.05-0.50% of Mg, and 0.06-0.30% of Ti, and, as impurities, 0.5% or less of Fe, 0.5% or less of Si, and 0.1% or less of Zn, with the remainder being Al and unavoidable impurities; the intermediate layer material contains 0.2-1.5% of Mg and at least one of 0.5-4% of Zn, 0.005-0.2% of In, and 0.01-0.2% of Sn, and, as impurities, 0.3% or less of Si, 0.3% or less of Fe, 0.05% or less of Cu, 0.05% or less of Mn, and 0.3% or less of Ti, with the remainder being Al and unavoidable impurities. The thickness of the intermediate layer material is 50 &mgr;m or more and no more than the thickness of the core material. The outer filler material and the inner filler material are Al—Si—Mg alloys, the outer filler material, preferably including at least one of 0.005-0.2% of In and 0.01-0.2% of Sn.

    摘要: An embroidery machine having a plurality of beds and corresponding heads. In each of the heads, a plurality of needle bars supporting needles and thread take up levers are provided. Each bed contains a rotary hook drive motor provided independent of a sewing machine motor which drives a spindle extending through the heads. The rotary hook drive motor is driven in synchronization with the spindle for performing embroidery stitching, but is driven independently of the spindle at a specific rotation angle range thereof based on number of stitching. In each bed, a conventional needle thread holding mechanism is dispensed with. By controlling rotation of the rotary hook drive motor, a residual end part of the needle thread has a sufficient length capable of avoiding disengagement of the residual end part from an eyelet of the needle at a thread cutting operation.

    摘要: A laminated non-woven fabric comprising a laminated material of an intermediate layer of a melt-blown non-woven fabric obtained by melt-blowing an olefin-type resin, an inner and outer layers of a spun-bonded non-woven fabric which chiefly consists of polyester-type fibers and in which the fibers are bonded together locally and at a coarse density, wherein the fibers constituting the inner and outer layers are inserted in the melt-blown non-woven fabric and are intermingled with fibers in the melt-blown non-woven fabric or in the spun-bonded non-woven fabrics of the opposite sides, so that the layers are coupled together as a unitary structure, and a process for producing the same. In the laminated non-woven fabric, the melt-blown non-woven fabric and the spun-bonded non-woven fabrics are fastened and stuck together free of defects to exhibit softness, porosity, water resisting property and like properties possessed by the melt-blown non-woven fabric as well as strength, hand, touch and like properties possessed by the spun-bonded non-woven fabric to their maximum degrees.

    摘要: A fluorescent tube is prevented from being wrongly attached and broken when being attached, and luminance nonuniformity of backlight due to luminance difference generated in a tube axis direction of the fluorescent tube is reduced. A backlight device 2 is provided with a plurality of fluorescent tubes 21 having electrodes 211 at both ends; a bundling member 213 for bundling wirings 212 pulled out from the electrode 211 on one side of two or more of the fluorescent tubes 21; and a conducting means 31 for achieving conduction between the electrodes of the two fluorescent tubes among the fluorescent tubes 21 by being connected with the bundling member 213. The conducting means 31 permits a current to be carried between the electrodes of the two fluorescent tubes 21, which are bundled by the one bundling member 213, and the conducting means are arranged on inverter circuit substrate 28, respectively, not to be adjacent to each other.
