Abstract:
The present invention is directed to hexagonal ferrite particles coated with a dispersant and having an exceptionally uniform particle size distribution that makes them particularly useful in the manufacture of high density magnetic tape.
Abstract:
Electrophoretic particles for electrophoretic display having excellent dispersibility and dispersion stability with time for insulating media, and being protected against coagulation, settling and the like, a process for production of the electrophoretic particles having high versatility for pigments to be used in response to a full-color display, and an electrophoretic display device using the electrophoretic particles that has an excellent memory property and is highly reliable are provided. The electrophoretic particles are formed using as at least a part of structure a pigment with at least a part of the surface covered with polyhydroxyalkanoate.
Abstract:
To improve the liquid barrier properties of a carpet, a repellency compound, such as a fluorochemical, is applied to the backstitch side or underside of the primary backing layer of a carpet.
Abstract:
A method of preparing an anti-fouling coating, the method including the steps of soaking polymeric gel beads in the presence of a solution including a solvent and a biocide to swell the gel beads and absorb both the solvent and the biocide therein, evaporating the solvent, rinsing any biocide of the surface of the beads, and mixing the beads in a coating material.

Abstract:
A process for producing a donor sheet for a thin-film formation comprising: while transporting a sheet on which a light-to-heat conversion layer has already been formed, forming a transfer layer on the light-to-heat conversion layer and drying the transfer layer.
Abstract:
Surface-modified solids bearing groups of the formula ISiR12nullRnullNH2nullnull(I),are prepared by reacting a solid having OH groups on a surface thereof with a cyclic silazane of the general formula II 1 where R is a divalent optionally substituted hydrocarbon radical optionally containing heteroatom containing groups, and R1 is a hydrogen atom, or a monovalent optionally substituted hydrocarbon or hydrocarbonoxy group optionally containing heteroatom-containing groups. The surface-modified solids are preferably metal oxide particles. Such surface-modified particles are useful in numerous products.
Abstract:
A method for producing a laminate having resin layers and thin metal layers by repeating a process unit comprising a step of laminating a resin layer by applying a resin material, a step of depositing a patterning material on the resin layer and a step of laminating a thin metal layer, predetermined times on a turning support (511), wherein the patterning material is stuck on the surface of the resin layer in a noncontact way. A laminate comprising a large number of laminate units each comprising a resin layer and a thin metal layer divided at an electric insulation stripe part can be produced stably. The laminate is applicable to production of a high performance small capacitor at low cost.
Abstract:
A process of forming a thick film structure comprising depositing a layer of thick film on a supporting carrier and drying the thick film layer in a plurality of controlled stages, and an apparatus for executing the process.
Abstract:
Solder compositions, solder pastes and methods of manufacturing thereof having a solder material coated with a coating material by an immersion coating process or an electroless plating process. The solder composition and solder pastes are substantially lead-free and have melting temperatures approaching those of traditional tin-lead solders.
Abstract:
In a process for coating particles, in which the particles are circulated upwards through a first spraying and drying zone and downwards through a second drying and residence zone, the capacity is increased and agglomeration avoided by using a lower temperature of gas supplied to said second residence and drying zone than the temperature of the gas supplied to said first spraying and drying zone.
