  • Patent number: 7307165
    Abstract: A process for easily and inexpensively producing an imidazo[1,2-b]pyridazin-3-ylsulfonamide derivative which has a substituent bonded to the 6-position carbon atom and is represented by the formula (II): (wherein R represents lower alkyl, lower cycloalkyl optionally substituted by lower alkyl, lower alkenyl, or lower alkynyl), the process comprising reacting an imidazo[1,2-b]pyridazine compound represented by the formula (I): (wherein X represents halogeno or lower alkyl optionally substituted by halogeno; Y represents hydrogen or SO2N?CH—NR1R2; and Z represents halogeno or OSO2R3) with an organometallic compound in the presence of a transition metal catalyst. The derivative is useful as an intermediate for herbicides.

  • Patent number: 6635826
    Abstract: A flat cable having parallel portions provided alternately with twisted pair portions in the longitudinal direction of the flat cable, wherein the parallel portions include a plurality of insulated core wires aligned parallel to each other and fused to each other. The twisted pair portions include twisted pairs each having two separately insulated core wires twisted together,wherein a plurality of the twisted pair portions in their surface, backside, and left and right side faces are surrounded and laminated by at least one pressure-sensitive adhesive tape, thermally fusible tape, pressure-sensitive adhesive shield tape, or thermally fusible shield tape.

  • Publication number: 20020144837
    Abstract: In a flat cable comprising parallel portions respectively provided alternately with twisted pair portions in the longitudinal direction of the flat cable, the parallel portion comprising a plurality of insulated core wires aligned parallel to each other and fused to each other, the twisted pair portion comprising twisted pairs each composed of two separately insulated core wires twisted together, the twisted pair portion in its surface, backside, and left and right side faces are surrounded and laminated by at least one pressure-sensitive adhesive tape, thermally fusible tape, pressure-sensitive adhesive shield tape, or thermally fusible shield tape. This construction can realize flat cables which, when bent, can prevent the separation or projection of the twisted pair at the twisted pair end and can maintain the appearance of the whole cable. Further, flat cables can be realized wherein the twisted pair portions can maintain stable transmission characteristics.

  • Patent number: 6412265
    Abstract: A plurality of perforations 6 has been defined on a plastic tape 5 to be laminated on insulated wire cores 2. Accordingly, intrusions of the plastic tape 5 in between each of pair-twisted sections 4 are elevated in laminating step of the plastic tape 5. As a result, collapses in the pair-twisted sections 4 decrease, and in addition, portions of a tape material corresponding to perforations 6 defined on the plastic tape 5 are replaced by air, so that dielectric constant between conductors of the insulated wire cores 2 decreases, whereby decrease in impedance can be reduced. Thus, a twisted flat cable I exhibiting flexibility and accompanying with no decrease in impedance in laminating step is provided.

  • Patent number: 4694633
    Abstract: A film wrapping machine for wrapping a film around a container comprising a rotary turntable assembly for transporting containers from one station to another. The machine includes a film supply unit for supplying each film onto a respective container carried by the turntable assembly, and a plurality of film retaining members one for each container carried by the turntable assembly. During the rotation of the turntable assembly, the film retaining meers are successively lifted to a raised position and are then rotated around the respective containers for turning the films therearound. Each film retaining member has suction openings defined therein in at least two rows, one row of the suction openings being adapted to suck one end of the respective film and the other row of the suction openings adapted to such a portion of the respective film adjacent the other end thereof. Rotation of the film retaining member results in the turning of the respective film around the associated container to form the film tube.

  • Patent number: 4379009
    Abstract: A method for sealing an object having a peripheral surface, surfaces substantially perpendicular to the peripheral surface and infinite enlongated bodies projecting from the surfaces perpendicular to the peripheral surface, which method comprises: wrapping the peripheral surface with a heat-shrinkable film in such a manner that both side edges of the film extend beyond the side edges of the peripheral surface; bonding longitudinal edges of the film to each other; and heating the heat-shrinkable film to permit the film to shrink to thereby seal the peripheral surface and a peripheral portion of the surfaces perpendicular to said peripheral surface, except said infinite elongated bodies.
