  • Patent number: 8051569
    Abstract: New and useful method of building a boiler frame significantly reduces the use of high load-lifting height crane and improves the operation efficiency despite bad weather. Multiple levels of steel supporting posts, which are established beforehand, are linked together with their top portion by beams and the 9th floor unit is fixed to the posts at an intermediate floor position temporarily. Suspension rods, which are suspended from lifting jacks, are then connected to the 8th floor unit and jacked up, while floor units made for lower than the 8th floor are connected on the ground to form a multi-floor unit. After connecting the multi-floor unit to the 9th floor unit the temporary fixation is released, the multi-floor unit is lifted up, and each floor unit is permanently fixed to the designated floor position repeatedly and respectively.

  • Patent number: 8034217
    Abstract: A liquid condensation system heats a liquid raw material under a decompressed circumstance and evaporates a volatile component from a liquid surface to condense the liquid raw material. Therefore, the liquid condensation system includes: liquid condensers, each of which condenses the liquid raw material; a vacuum pump that is in communication with the liquid condensers; and a warm water circulation system as a heating source that heats the liquid raw material in the liquid condensers. The volatile component evaporated in the liquid condensers is led to the outside of the liquid condensers through vapor lines. The condensed liquid that is not evaporated in the liquid condensers is led to the outside of the liquid condensers through condensed-liquid lines. Condensed-liquid-line adjusting valves are interposed on the condensed-liquid lines, and heaters are attached to the condensed-liquid lines. A control unit controls the heaters and the condensed-liquid-line adjusting valves.

  • Patent number: 8010999
    Abstract: According to a cable installation support and management system of the present invention, each worker downloads the operation information which supports operations on cables authorized for use onto the portable terminal carried by the worker, the operation information being associated in advance with cable identification information and provided by the server. Then, the worker reads the cable identification information about a cable from the cabling data card attached to the end of the cable using the reading device of the portable terminal. Based on the cable identification information, the worker acquires operation information about the appropriate cable from the downloaded operation information and displays the acquired operation information on the display device of the portable terminal. This allows the worker to perform necessary operations by referring to the operation information displayed on the display device.

  • Patent number: 7992724
    Abstract: To reuse support plate and to fix a membrane sheet by the same method both in a new product manufacturing and in regeneration. In a flat membrane element including a deposit fixed portion formed by lapping a membrane sheet performing solid-liquid separation onto a support plate supporting the membrane sheet and by emitting a laser to a circumferential edge of the membrane sheet to deposit fix the member sheet onto the support plate, and making an inside of the membrane sheet surrounded by the deposit fixed portion be a solid-liquid separating area; an embrocation having laser absorption property is applied on the surface of the membrane sheet of the deposit fixed portion. At the time of regeneration, such a portion of the membrane sheet that corresponds to the solid-liquid separating area is cut off and, after that, a new membrane sheet is lapped on the embrocation and the new membrane sheet and the embrocation are deposit fixed by a laser.

  • Publication number: 20110190158
    Abstract: According to an aspect of the present invention, a pair of oligonucleotide strands are anchored onto the surface of a substrate by immobilizing one of the ends thereof onto the substrate. Each of the immobilized oligonucleotide strands is bound to a target nucleic acid sequence (single-stranded) having complementary sequences thereto to form a cross-linked structure on the substrate, thereby forming a finely reticulated space. Ligands are captured by this reticulated space through physical adsorption and caused to color with active substances reactive to the ligands. As a result of this, the present invention is capable of highly sensitively detecting even an exceedingly small concentration of a particular target nucleic acid sequence to be detected, at low cost and for a short time.
