A third cycle, in which the second medium is circulated and heat is exchanged with the first medium through the third heat exchanger, shares the indoor units with the second cycle. Flow path switching valves switch flow paths between the second cycle and third cycle. Before the first heat exchanger is defrosted, a halted indoor unit is filled with the second medium in the third cycle with its fan being halted. The third heat exchanger functions as an evaporator during a defrosting operation. | 02-23-2012 |
| 20120043054 | AIR-CONDITIONING APPARATUS - In a first cycle, a first heat exchanger, in which a first medium exchanges heat with the outside air, a second heat exchanger and a third heat exchanger, in which heat is exchanged between the first cycle and a second cycle and between the first cycle and a third cycle, respectively, are connected in series with a first reducing valve and a second reducing valve. In the second cycle and the third cycle that convey cooling energy and heating energy, the flow rates of a second medium in respective branches are adjusted by flow-rate-adjusting valves in accordance with the entrance and exit temperatures of indoor units, and the total flow rate is determined by controlling the rotation speed of a pump by a minimum resistance method. Therefore, even if there are a plurality of loads and the loads change significantly, a stable controlling operation is realized, enabling a highly efficient operation. | 02-23-2012 |

| 20120041756 | VOICE RECOGNITION DEVICE - Voice recognition is realized by a pattern matching with a voice pattern model, and when a large number of paraphrased words are required for one facility, such as a name of a hotel or a tourist facility, the pattern matching needs to be performed with the voice pattern models of all the paraphrased words, resulting in an enormous amount of calculation. Further, it is difficult to generate all the paraphrased words, and a large amount of labor is required. A voice recognition device includes: voice recognition means for applying the voice recognition to an input voice by using a language model and an acoustic model, and outputting a predetermined number of recognition results each including a set of a recognition score and a text representation; and N-best candidate rearrangement means for: comparing the recognition result to a morpheme dictionary held in a morpheme dictionary memory; checking whether a representation of the recognition result can be expressed by any one of combinations of the morphemes of the morpheme dictionaries; correcting the recognition score when the representation can be expressed; and rearranging an order according to the corrected recognition score so as to acquire recognition results. | 02-16-2012 |

| 20120039045 | POWER MODULE AND METHOD FOR DETECTING INSULATION DEGRADATION THEREOF - A method and device for detecting insulation degradation of a power module, which detects, in advance, degradation of an insulating sheet based on a current change immediately before breakdown of an insulation characteristic from a current value of a current flowing through the insulating sheet, thereby detecting a failure of a power module caused by the degradation of insulation. The device includes: a current detector sampling and detecting a current value of a current flowing through an insulating sheet of the power module at a predetermined time interval; a calculator determining, based on the current value, a state in which the insulation characteristic of the insulating sheet is so degraded that the breakdown is imminent, and outputting a degradation determination result of YES when it is determined that the insulating sheet is in the state immediately before the breakdown; a current storage storing a current value i(n−1) at a previous sampling time point; and an alarm generating an alarm in response to the degradation determination result of YES. The calculator outputs the degradation determination result of YES when a present current value in exceeds ten times the previous current value i(n−1). | 02-16-2012 |
