  • Patent number: 7507682
    Abstract: In manufacturing a ceramic multi-layer wiring substrate which is formed by stacking a plurality of ceramic layers and which includes an internal wiring, a ceramic paste is printed using a screen printing process on a part of a ceramic green sheet to be a ceramic layer having the internal wiring formed thereon which part does not include the internal wiring, to form between the ceramic layers a ceramic filling layer including a same ceramic component as that in the ceramic layers which ceramic filling layer is not formed on the internal wiring. The ceramic paste includes a ceramic component, an acrylic resin, and a cellulose resin, and loss factor tan ? of the paste represented by (loss modulus)/(storage modulus) in a dry condition after printing is equal to or greater than loss factor tan ? of a conductor paste layer to be the internal wiring in a dry condition.

  • Publication number: 20080233416
    Abstract: A paste composition comprises inorganic particles; and a binder containing a copolymer made by copolymerizing a mixture. The mixture comprises a first (meth)acrylic ester whose homopolymer has a first glass transition temperature Tg[h]; and a second (meth)acrylic ester whose homopolymer has a second glass transition temperature Tg[l] lower than the first glass transition temperature Tg[h]. The total molar fraction of the first and second (meth) acrylic esters in the mixture is 80 mol % or more. The first and the second glass transition temperatures Tg[h] and Tg[L] satisfy the relationships Tg[h]?100° C. and Tg[h]?Tg[l]?50° C.

  • Patent number: 7371299
    Abstract: A set of resin sheets includes a plurality of resin sheets. Each resin sheet is disposed in a site to be a surface recess or inner void in a ceramic green sheet to be laminated, and a plurality of such ceramic green sheets each with the resin sheet disposed therein are laminated and fired, whereupon the resin sheets are removed by thermal decomposition during the firing. In the set of resin sheets, the relation of Ta<Tb?Tc is satisfied wherein Ta (° C.) indicates an 80% weight reduction temperature of an uppermost resin sheet, Tb (° C.) indicates an 80% weight reduction temperature of a lowermost resin sheet, and Tc (° C.) indicates a 20% weight reduction temperature of a resin binder which is contained in the ceramic green sheets in which the green sheets are disposed.

  • Patent number: 6716159
    Abstract: A cover tube, which is formed to be opened only at its upper surface and closed at its remaining portions, is disposed so as to be attachable and detachable beneath a hanger for suspending and holding an endoscope or an endoscope treatment member and so as to surround the tip end portion of the endoscope or the endoscope treatment member in a state of being suspended from and held by the hanger.

  • Patent number: 6627122
    Abstract: A powdery flame retardant which is obtained by mixing a flame retardant which is liquid or a viscous solid at ordinary temperature with an inorganic fibrous substance to adhere or adsorb the retardant to the fibrous substance, and which comprises 5 to 70 wt. % the flame retardant and 95 to 30 wt. % the fibrous substance. The powdery flame retardant can be easily handled because it is a powder, and is obtained by a simple and industrially advantageous method. It produces a remarkable effect that the performance of the liquid or viscous flame retardant is not impaired.

  • Patent number: 6521689
    Abstract: An object of this invention is to impart excellent flame retardancy to an aromatic polyamide resin without use of a halogen compound which is responsible for generation of gases harmful to the human body and without decreasing preferred properties (e.g. mechanical properties, and molding processability) inherently possessed by aromatic polyamide resins, the flame-retardant aromatic polyamide resin composition of this invention comprising (a) 100 parts by weight of an aromatic polyamide resin, (b) 0.1 to 100 parts by weight of a crosslinked phosphazene compound which is a compound crosslinked with a crosslinking group, such as phenylene groups, the crosslinking group being interposed between the two oxygen atoms left after the elimination of phenyl groups from the phosphazene compound, no free hydroxyl group being present in the molecule, the amount of all phenyl groups in the crosslinked compound being 50 to 99.
