|20150257277||METHOD FOR MANUFACTURING MULTILAYER SUBSTRATE, MULTILAYER INSULATION FILM, AND MULTILAYER SUBSTRATE - A manufacturing method of a multilayer substrate uses a multilayer insulation film which includes a first insulation layer and a second insulation layer laminated on one surface of the first insulation layer, the second insulation layer being configured such that, in partially removing the second insulation layer, only the second insulation layer is enabled to be selectively removed to form a groove having a depth equal to a thickness of the second insulation layer on an obtained insulation layer. The manufacturing method includes: laminating the multilayer insulation film on a surface of a circuit board; selectively and partially removing only the second insulation layer out of the first insulation layer and the second insulation layer to form the groove having a depth equal to the thickness of the second insulation layer on the obtained insulation layer; and forming metal wiring within the groove formed on the insulation layer.||09-10-2015|
|20150247777||LEAKAGE DETECTOR, LEAKAGE DETECTION METHOD, AND PIPE NETWORK MONITORING APPARATUS - Provided is a leakage detector which is capable of exhibiting high sensitivity to vibration-sounds caused by water leakage from a synthetic resin pipe and thus setting an installation span longer to thereby make it possible to more efficiently perform a water leakage inspection for a synthetic resin pipe. The leakage detector (||09-03-2015|
|20150240067||POLYVINYL ACETAL-BASED RESIN COMPOSITION - The present invention provides a polyvinyl acetal resin composition exerting excellent mechanical strength over a wide temperature range from low temperatures to high temperatures. The present invention provides a polyvinyl acetal resin composition containing a polyvinyl acetal resin and a resin having a crosslinked structure, the polyvinyl acetal resin composition having a structure in which the resin having a crosslinked structure is dispersed as a dispersed phase in the polyvinyl acetal resin as a continuous phase, the polyvinyl acetal resin composition having a maximum value of a loss tangent derived from the polyvinyl acetal resin at 40° C. or higher and a maximum value of a loss tangent derived from the resin having a crosslinked structure at 10° C. or lower in measurement of a dynamic viscoelasticity spectrum at a frequency of 10 Hz.||08-27-2015|
|20150240019||REACTANT OF SILICON RESIN POLYCONDENSATE PARTICLES AND POLYVINYL CHLORIDE, METHOD FOR MANUFACTURING SAID REACTANT, VINYL CHLORIDE RESIN COMPOSITION, AND METHOD FOR MANUFACTURING VINYL CHLORIDE RESIN COMPOSITION - Provided is a reaction product of silicone resin polycondensate particles and polyvinyl chloride wherein the reaction product can impart excellent impact resistance and chemical resistance. The reaction product of silicone resin polycondensate particles and polyvinyl chloride according to the present invention is obtained by causing reaction of a material containing silicone resin polycondensate particles and vinyl chloride monomer. The silicone resin polycondensate particles are obtained by causing reaction of a material mixture containing a first organosilicon compound having a structural unit represented by a formula (1) and serving as a siloxane, a second organosilicon compound represented by a formula (2), and a third organosilicon compound represented by a formula (3A) or formula (3B).||08-27-2015|
