20140208787 | REFRIGERATION APPARATUS - An air conditioning system includes a refrigerant circuit including a compressor, an indoor heat exchanger, a first expansion valve, a gas-liquid separator, a second expansion valve, and an outdoor heat exchanger which are sequentially connected together to perform a two-stage expansion refrigeration cycle. The refrigerant circuit further includes: a gas injection pipe through which intermediate-pressure gas refrigerant in the gas-liquid separator flows into an intermediate port of the compressor, and a liquid-gas heat exchanger configured to exchange heat between low-pressure gas refrigerant obtained by evaporating refrigerant in the outdoor heat exchanger and travelling toward the compressor and intermediate-pressure liquid refrigerant travelling from the gas-liquid separator toward the second expansion valve. | 07-31-2014 |
20150090803 | AIR CONDITIONING SYSTEM - An air conditioning system includes a heat pump having a refrigerant radiator, a gas furnace unit having a heating section to heat passing air, a blower generating air flow through the radiator and the heating section, and a controller controlling operation of the heat pump unit, the gas furnace unit, and the blower. The controller has a first operating mode in which the gas furnace unit operates alone as a heat source unit, a second operating mode in which the heat pump unit operates alone as a heat source unit, and a third operating mode in which the gas furnace unit and the heat pump unit operate at the same time as a heat source unit. The controller is configured to select the operating modes based on a parameter relating to outside air temperature that is the temperature of outside air. | 04-02-2015 |
20150219342 | AIR CONDITIONING SYSTEM - An air conditioning system includes a heat pump unit including a radiator usable with a refrigerant, a gas furnace unit including a heating section arranged to heat passing air, a blower arranged to generate an air flow that passes through the radiator and the heating section, a first temperature sensor provided in a room, and a controller configured to control each action of the heat pump unit, the gas furnace unit, and the blower. The temperature sensor detects an indoor temperature in the room. The controller causes the gas furnace unit to operate as a heat source unit when a difference value obtained by subtracting the indoor temperature from a set temperature is equal to or greater than a first threshold at startup, and causes the heat pump unit to operate as a heat source unit when the difference value is less than the first threshold at startup. | 08-06-2015 |
20150219343 | AIR CONDITIONING SYSTEM - An air conditioning system includes a heat pump unit including a radiator usable with a refrigerant, a gas furnace unit including a heating section arranged to heat passing air, a blower arranged to generate an air flow that passes through the radiator and the heating section, and a controller configured to control each action of the heat pump unit, the gas furnace unit, and the blower. The controller operates either the heat pump unit or the gas furnace unit as a heat source unit, generates a capacity command used to variably adjust operating capacity of the heat source unit, and executes switch control in order to switch the heat source unit from either one of the heat pump unit or the gas furnace unit to the other when an operating capacity level designated in the capacity command is within a predetermined numerical range for a predetermined time. | 08-06-2015 |
20150276280 | REFRIGERATING APPARATUS - In an air conditioner which is a refrigerating apparatus, a superheat degree controller is provided, which is configured to control, in an evaporation mode of an outdoor heat exchanger, the opening degree of an expansion valve such that the superheat degree of refrigerant whose flows are joined together after passing through a main heat exchange part and an auxiliary heat exchange part reaches a predetermined superheat degree. Moreover, in the air conditioner, a flow volume adjustment valve configured to adjust, in the evaporation mode of the outdoor heat exchanger, a flow ratio of refrigerant in the heat exchange parts and a flow ratio controller configured to control the flow volume adjustment valve such that refrigerant temperatures after passage through the heat exchange parts are substantially equal to each other are provided. | 10-01-2015 |

20110230826 | MICROJET DRUG DELIVERY SYSTEM - The present invention relates to a novel type of a needle-free drug delivery system in which strong energy such as a laser beam is focused inside liquid contained in a sealed pressure chamber to cause bubble growth and the volume expansion in the sealed pressure chamber due to the bubble growth so as to elongate an elastic membrane, so that an instantaneous pressure is applied to a drug solution contained in a drug microchamber adjacent to the elastic membrane to allow the drug solution to be injected in the form of a liquid microjet, thereby enabling the drug solution to rapidly and accurately penetrate into the bodily tissues of the patient. | 09-22-2011 |
20140033822 | ULTRASONIC TRANSDUCER, AND ULTRASONIC WAVE GENERATING APPARATUS AND ULTRASONIC SYSTEM INCLUDING THE SAME - An ultrasonic transducer, and an ultrasonic wave generating apparatus and an ultrasonic system including the same. The ultrasonic transducer includes a light-absorbing layer configured to absorb light incident on the light-absorbing layer and to generate heat based on the absorbed light; and a thermoelastic layer which is disposed on the light-absorbing layer and which is configured to thermally expand based on the heat to generate ultrasonic waves. | 02-06-2014 |
20150265770 | MICROJET DRUG DELIVERY SYSTEM USING ERBIUM YAG LASER - A microjet drug delivery system includes a pressure chamber which has a predetermined storing space and of which a closed inner portion is hermetically filled with water, a drug chamber which is disposed adjacent to the pressure chamber and is configured to store a drug solution in a predetermined storing space and where a micro nozzle ejecting the drug solution as a microjet to an outside is formed at one side thereof, an elastic membrane which is disposed between the pressure chamber and the micro drug chamber, and a laser unit which irradiates the pressure driving liquid stored in the pressure chamber with laser to generate bubble in the pressure driving liquid. The laser unit irradiates a laser beam having an oscillation wavelength range of 2.8 μm to 3.0 μm, and in particular, an Er:YAG laser having a wavelength of 2.94 μs (2940 nm) is used. | 09-24-2015 |
