20090143654BIOLOGICAL MEASUREMENT SYSTEM - This invention measures cerebral blood volume changes to evaluate, from properties of low-frequency components of such changes and heart rate changes calculated by analysis, a distribution of cerebral blood vessel hardness and its with-time change to thereby estimate and display diseased and dangerous portions based on the evaluation. Briefly, the above-noted object is attainable by a biological measurement system having a cerebral blood volume measurement unit which measures a regional cerebral blood volume of a body under test, an analyzer unit that analyzes a signal measured by the cerebral blood volume measurement unit, an extraction unit for extracting, based on an output of the analysis unit, information concerning a regional cerebral blood vessel state of the test body, and a display unit which displays a measurement result of the cerebral blood volume measurement unit, an analysis result of the analyzer unit or an extraction result of the extraction unit.06-04-2009
20090306059CYCLIC AMINE DERIVATIVE HAVING SUBSTITUTED ALKYL GROUP - A compound having the general formula (I), pharmacologically acceptable salts thereof or prodrugs thereof:12-10-2009
20100298120PHOTOCATALYST FILM, PROCESS FOR PRODUCING PHOTOCATALYST FILM, ARTICLE AND METHOD FOR HYDROPHILIZATION - A photocatalyst film of which at least one main surface contains photo-semiconductor particles; said main surface being a surface that becomes hydrophilic by irradiation with light, wherein the hydrophilization speed thereof when it is irradiated with light having a half-value width of 15 nm or less after kept in a dark place is less than 2 (l/deg/min/1011-25-2010
20110088421AIR CONDITIONING APPARATUS - A heat source-side refrigerant circuit A including a compressor 04-21-2011
201101121035-HYDROXYPYRIMIDINE-4-CARBOXAMIDE COMPOUND - The present invention provides compounds which promote erythropoietin production. Compounds represented by the following general formula (1) or pharmacologically acceptable salts thereof are provided:05-12-2011
20110113802AIR CONDITIONER - A multi-chamber air conditioner including a heat-source side refrigerant circuit in which a compressor, an outdoor heat exchanger, a first heat exchanger, a refrigerant flow-rate controller, and a second heat exchanger are connected in series, a first use-side refrigerant circuit in which the first heat exchanger and an indoor heat exchanger are connected in series, and a second use-side refrigerant circuit in which the second heat exchanger and the indoor heat exchanger are connected in series, and a heat-source side refrigerant circulating in the heat-source side refrigerant circuit and a use-side refrigerant circulating in the use-side refrigerant circuit are heat-exchanged in the first heat exchanger. The heat-source side refrigerant circulating in the heat-source side refrigerant circuit and the use-side refrigerant circulating in the use-side refrigerant circuit are heat-exchanged in the second heat exchanger.05-19-2011
20110192184AIR-CONDITIONING APPARATUS AND RELAY UNIT - To obtain an air-conditioner apparatus that can achieve energy-saving without making refrigerant circulate up to an indoor unit and whose construction work is easy. A refrigeration cycle is configured by connecting a compressor, a four-way valve, a heat source side heat exchanger, expansion valves, and intermediate heat exchangers by piping. A heat medium circulation circuit is configured by connecting intermediate heat exchangers, pumps, and use side heat exchangers by piping. The outdoor unit that is installed in a space such as outdoors of the building and accommodates the compressor, the four-way valve, and the heat source side heat exchanger, and the relay unit that is installed in a non-subject space which is different from an indoor space and is on a installation floor separated by two or more floors and accommodates the expansion valves, the pump, and intermediate heat exchangers are connected by two pipelines. The relay unit and an indoor unit that accommodates use side heat exchangers and is installed at a position where an indoor space can be air-conditioned are connected by two pipelines from outside of the wall which is a partition between inside and outside of the room.08-11-2011
20110197608AIR-CONDITIONING APPARATUS - A refrigeration cycle is configured by connecting a compressor that compresses the refrigerant, a four-way valve that switches the circulation path of the refrigerant, a heat source side heat exchanger that exchanges heat, expansion valves that adjust the pressure of the refrigerant, and two or more intermediate heat exchangers that exchange heat between the refrigerant and the heat medium to heat and cool the heat medium, by piping. A heat medium circulation circuit is configured by connecting two or more intermediate heat exchangers, pumps that pressurize the heat medium, two or more use side heat exchangers that exchange heat between the heat medium and the air in the indoor space, and flow path switching valves that switch paths of the heated heat medium or the cooled heat medium to the use side heat exchangers, by piping.08-18-2011
