  • Patent number: 7595362
    Abstract: Provided is curable resin composition which gives a cured article excellent in chemical resistance, dielectric properties, low water-absorption, heat resistance, flame retardance, and mechanical properties and which is usable in applications such as dielectric materials, insulating materials, heat-resistant materials, and structural materials. The curable resin composition includes a component (A) which is a polyphenylene ether oligomer having a number-average molecular weight of 700 to 4,000 and having a vinyl group at both end and a component (B) which is a solvent-soluble polyfunctional vinylaromatic copolymer which has structural units derived from monomers including a divinylaromatic compound (a) and an ethylvinylaromatic compound (b) and in which the content of repeating units derived from the divinylaromatic compound (a) is 20 mol % or higher, the ratio of the amount (wt. %) of the component (A) to that (wt. %) of the component (B) being (20 to 98):(2 to 80).

  • Publication number: 20020119440
    Abstract: The present invention provides cell lines expressing one or more recombinant peripheral nerve (PN) sodium channels, preferably a human PN sodium channel. The invention also provides methods for preparing said cell lines. The invention also pertains to the use of said cell lines for the identification of PN sodium channel agonists, antagonists or modulators and methods for the identification of said agonists, antagonists or modulators. The invention also provides pharmaceutical compositions comprising said agonists, antagonists or modulators. The invention also is concerned with the use of agonists, antagonists or modulators in the manufacture of a medicament for the treatment of chronic pain disorders.

  • Patent number: 6421932
    Abstract: While being transferred in substantially horizontal state along a predetermined path of transfer by a conveyer means, a substrate plate is dried by a jet of compressed air which is spurted out from a slit-like mouth of an air knife nozzle crosswise of the entire width of the substrate plate and at a predetermined angle of incidence with respect to a drying surface of the substrate plate to scrape off a liquid. The angle of incidence of jet air is made shallower as soon as the substrate on the conveyer means comes to a point of entry to an air blasting zone and is made deeper at latest when the substrate plate comes to a position immediately before a point of disengagement from the air blasting zone.
