20100199716 | GAS-LIQUID SEPARATOR AND AIR CONDITIONER EQUIPPED WITH THE SAME - To improve the separation efficiency of a gas-liquid separator in the gas-liquid separator and an air conditioner, the gas-liquid separator having a vessel with an inlet pipe and an outlet pipe is arranged such that an exit end section of the inlet pipe is formed to be closed or to have a gap, an expanded end section having a width greater than the diameter of that portion of the inlet pipe which crosses a container of the gas-liquid separator is provided, and that a lateral hole is formed in a side face of the expanded end section. Refrigerant vapor and refrigerant liquid are efficiently separated from each other at the expanded end section, and this improves separation efficiency of the gas-liquid separator. | 08-12-2010 |
20100324337 | PROCESS FOR PRODUCING HIGH-PURITY CHLOROPHOSPHITE - There is provided a process capable of preventing the adhesion of a catalyst to an evaporator in a step of separating a chlorophosphite as a target substance from a reaction liquid by evaporation. The process includes a first step of allowing phosphorus trichloride and a phosphorous acid triester represented by (RO) | 12-23-2010 |
20100331126 | RACKET - A tennis racket includes a frame that includes a shaft and a looped frame portion, the shaft having a grip formed on one end side thereof, the frame portion being joined to the other end side of the shaft and forming a hitting face with a string being strung across and a plurality of insertion holes that provide communication between an inner peripheral side surface and an outer peripheral side surface of the frame portion and through which the string is inserted. Shock absorbing portions and hard portions are provided in an alternating fashion on at least a part of the outer peripheral side surface of the frame portion. Each shock absorbing portion is formed between insertion holes that are adjacent to each other. Each hard portion is formed between insertion holes that are adjacent to each other and is less elastically deformable than the shock absorbing portion. | 12-30-2010 |
20110283728 | SCALE DEPOSITION DEVICE AND WATER HEATER - Provided is a water heater, which allows efficient deposition of a scale component dissolved in water so as to reduce adhesion of the scale to a heat-transfer channel. The water heater includes: scale deposition means including a tank, an anode and a cathode provided in the tank so as to be opposed to each other, and a first power supply for applying a voltage between the anode and the cathode, the scale deposition means depositing a scale component dissolved in water retained in the tank; a heat-transfer channel provided at downstream of the scale deposition means, for guiding the water; and a heat source for heating the water by heat exchange in the heat-transfer channel, in which the scale deposition means includes oxygen-gas supplying/dissolving means for supplying an oxygen gas to a water feed pipe for feeding the water to the tank and dissolving the oxygen gas in the water. | 11-24-2011 |
20140016265 | HIGH-DENSITY SERVER AGGREGATING EXTERNAL WIRES FOR SERVER MODULES - A high-density server includes a plurality of server enclosures, each of which includes an enclosure frame with a pair of front decks and a rear opening, an enclosure element having a power supply unit, and a pair of server modules having module connectors. The enclosure element is positioned in the rear side of the enclosure frame. The module connector of the server module is detachably connected to the front connector of the power supply unit when the server module moves along the front deck in an insertable/removable manner inside the enclosure frame. A cooling fan is positioned in the front side of the server module relative to the rear opening of the enclosure frame. An external interface is attached to the rear end of the server module or installed in the enclosure element, thus preventing a mess in the front face of the server enclosure due to external wires. | 01-16-2014 |
20140144607 | WATER HEATER AND FLOW RATE CONTROL METHOD - A water heater in which by applying pulsation of a liquid to be heated which circulates between a tank and a heat exchanger, scale that has been deposited on the inner wall (heat-transfer surface) of a to-be-heated liquid flow channel in a heat exchanger is detached, and the number of times of circulation of the liquid to be heated which circulates between the tank and the heat exchanger is controlled to be three times or less. The number of times of circulation is determined, based on the entire volume of the to-be-heated liquid stored in the tank, a boiling time to be taken for the entire volume of the to-be-heated liquid in the tank to reach a predetermined temperature, and the flow rate of the to-be-heated liquid which passes through the to-be-heated liquid flow channel. | 05-29-2014 |
