Patent application numberDescriptionPublished
20090051434SIGNAL TRANSFER CIRCUIT AND CIRCUIT DEVICE USING SAME - A signal transfer circuit appropriate for use in realizing both high circuit stability and high current driving ability is disclosed. Signal transfer circuit A has current transfer circuit 02-26-2009
20090202859COMPOSITE COATED ZING-CONTAINING PLATED STEEL MATERIAL SUPERIOR IN CORROSION RESISTANCE, BLACKENING RESISTANCE, COATING ADHESION, AND ALKALI RESISTANCE - The present invention provides a composite coated zinc-containing plated steel material different from the plated steel materials treated by conventional chromate replacement technologies and superior in all of corrosion resistance, blackening resistance, coating adhesion, and alkali resistance. The composite coated zinc-containing plated steel material of the present invention is characterized by having a composite coating formed by coating and drying on the surface of a plated steel material a treatment solution containing a basic zirconium compound, vanadyl (VO08-13-2009
20100014983TURBINE BLADE - The present invention provides a turbine blade that is exposed to a high temperature atmosphere at relatively high temperatures and to a low temperature atmosphere at relatively low temperatures, including: a concave-curve-like pressure surface that is concaved along a flow direction of fluid; a convex-curve-like suction surface that is convexed along the flow direction of the fluid; and a concave and convex formation device which causes a concave and convex portion along the flow of the fluid to appear on the suction surface when the turbine blade is exposed to the low temperature atmosphere, and which turns the suction surface into a smooth surface along a convex curve surface of the suction surface when the turbine blade is exposed to the high temperature atmosphere. With this construction, it is possible to reduce a pressure loss of the turbine blade at high Reynolds numbers in the low temperature atmosphere without increasing a pressure loss of the turbine blade at low Reynolds numbers in the high temperature atmosphere.01-21-2010
20100172749WALL OF TURBO MACHINE AND TURBO MACHINE - The invention relates to wall of a turbo machine having a cascade of blades. The wall includes: a first platform facing a first passage between blades in the cascade of blades; and a second platform facing a second passage between adjacent cascade of blades on an upstream side and cascade of blades on a downstream side, and having a circumferential outline having a distribution of radial positions. According to the invention, loss due to disturbance of flow through the gap of axially adjacent walls can be reduced.07-08-2010
20100232798BIT IDENTIFICATION CIRCUIT - A bit identification circuit includes a multiphase clock generating unit that outputs multiphase clocks, a phase selecting unit that samples the input data signals using the multiphase clocks and selects a sampled result out of a plurality of sampled results, a correcting unit that thins a part of bits of the sampled result selected by the phase selecting unit based on the difference in bit rates, and a rate selecting unit that selects based on a selection signal for identifying the data signals and outputs one of an output of the correcting unit and an output of the phase selecting unit.09-16-2010
20110027325ORALLY-ADMINISTERED AGENT - An orally-administered agent according to the present invention comprises: a medicine-containing layer containing a medicine and having surfaces; collapse-controlling layers respectively provided on the surfaces of the medicine-containing layer; and gel-forming layers respectively provided on the collapse-controlling layers, wherein the gel-forming layers are swelled and gelatinized by absorbing water to form a gel. The collapse-controlling layers are constituted of a material containing a stomach-soluble material to be dissolved by being in contact with gastric juice. The orally-administered agent according to the present invention can be swallowed with ease and release the medicine in intended parts, in particular, the stomach of a living body.02-03-2011
20110027611ZINC-BASED PLATED STEEL SHEET EXCELLENT IN SURFACE ELECTRICAL CONDUCTIVITY HAVING PRIMARY RUST PREVENTIVE THIN FILM LAYER - A zinc or zinc alloy plated steel sheet expressing a performance provided with both corrosion resistance and surface conductivity is provided. The zinc or zinc alloy plated steel sheet of the present invention is a zinc or zinc alloy plated steel sheet having an arithmetic average roughness Ra of a zinc-plated layer surface defined by JIS B 0601, obtained by a stylus-type surface roughness meter defined by JIS B 0651, of 0.3 μm to 2.0 μm and a maximum peak height Rp of 4.0 μm to 20.0 μm, wherein the arithmetic average roughness Ra (peak) obtained by measuring a range of evaluation length of 20 μm of peak parts of 80% or more of the Rp by an electron beam 3D roughness analyzer is 70% or more of the arithmetic average roughness Ra (average) obtained by measuring a range of evaluation length of 20 μm of parts of a height of ±20% about an average line, obtained by a stylus-type surface roughness meter, by an electron beam 3D roughness analyzer.02-03-2011
20110182954ORALLY-ADMINISTERED AGENT - An orally-administered agent is provided. The orally-administered agent comprises an intestinal medicine-containing layer containing a medicine to be released in intestines and having surfaces; intestinal collapse-controlling layers provided directly or through an arbitrary layer on the surfaces of the intestinal medicine-containing layer, respectively, at least a part of the intestinal collapse-controlling layers being collapsed in the intestines, and each of the intestinal collapse-controlling layers having a surface opposite to the intestinal medicine-containing layer; and gel-forming layers provided directly or through an arbitrary layer on the sides of the surfaces of the intestinal collapse-controlling layers, respectively, wherein the gel-forming layers are swelled and gelatinized by absorbing water to form a gel. The intestinal collapse-controlling layers are constituted of a material containing an enteric material to be dissolved by being in contact with a body fluid in the intestines. The orally-administered agent according to the present invention can be swallowed with ease and can release a medicine at intended parts of a living body (in particular, within intestines).07-28-2011
