| 20100039737 | MAGNETIZING INRUSH CURRENT SUPPRESSION DEVICE FOR TRANSFORMER AND CONTROL METHOD OF SAME - To provide a magnetizing inrush current suppression device for transformer and control method of same, which accurately calculates the residual magnetic flux when a transformer installed in a non-solidly earthed system, is interrupted by circuit breakers, and which enables suppression of the magnetizing inrush current occurring when three single-phase circuit breakers or single-phase circuit breakers are used for simultaneously supplying power to three phases of the transformer, without providing a circuit breaker with a resistor or other equipment to enlarge the circuit breaker. The device has steady-state magnetic flux calculation means for calculating the line-to-line steady-state magnetic flux of three-phase power supplies, residual magnetic flux calculation means for calculating the primary line-to-line residual magnetic flux of the transformer when the circuit breakers interrupt the transformer, phase detection means for detecting a phase at which the polarity and magnitude of the calculated steady-state magnetic flux and residual magnetic flux coincide for each line-to-line. Closing control means firstly causes only two-phase of the circuit breakers, which are connected with the line-to-line, to close at the detected phase, and then causes the remaining one-phase circuit breaker to close. | 02-18-2010 |

| 20090010430 | Streaming system for distributing encrypted compressed image data, and streaming method therefor - The present invention is directed to a streaming system for encrypting compression-encoded image data to distribute it via network of a predetermined transport protocol, and a streaming server used in this system transmits, to a client terminal, on the RTP packet basis, stream data encrypted so that encryption is performed every encryption block size from the leading portion of each GOP without encrypting the last data having less than encryption block size. In this instance, portions of prior and/or posterior stream data are stored into an extended area of RTP header so that size of stream data transmitted every RTP packet is integral multiple of encryption block size. Further, size information of added prior additional data and/or posterior additional data are also stored into the extended area. This streaming server suppresses increase in size by encryption to have ability to support both real time production and down-load reproduction without replacement of encryption. | 01-08-2009 |
| 20100023980 | Information Processing Apparatus, Terminal Apparatus, and Program - An information processing apparatus includes a content purchase history storage unit in which a content purchase history for each user is stored, a metadata storage unit in which metadata of a plurality of contents is stored, and a metadata retrieval unit to retrieve, upon reception of a metadata retrieval request that is sent from a terminal apparatus of the user via a network and includes information for identifying a user and a retrieval condition, metadata of a content that meets the retrieval condition from the metadata storage unit, judge whether the content retrieved has already been purchased based on the content purchase history of the user that is stored in the content purchase history storage unit, and send a retrieval result of the metadata of the content that includes a judgment result to the terminal apparatus via the network as a metadata retrieval response. | 01-28-2010 |

| 20110233045 | METHOD OF PURIFYING HYDROCHLORIC ACID - Provided is a method of purifying hydrochloric acid by removing an organic substance having a boiling point of −25° C. to 120° C. under atmospheric pressure from a first organic substance-containing hydrochloric acid that contains the organic substance and has a hydrogen chloride concentration higher than an azeotropic hydrogen chloride concentration under atmospheric pressure. The method includes the step of subjecting a second organic substance-containing hydrochloric acid to distillation using a distillation tower under atmospheric pressure, to distill out the organic substance from a top of the distillation tower. The second organic substance-containing hydrochloric acid is obtained by mixing the first organic substance-containing hydrochloric acid and water or dilute hydrochloric acid and has the hydrogen chloride concentration lower than the azeotropic hydrogen chloride concentration under atmospheric pressure. | 09-29-2011 |
| 20110236296 | METHOD OF PURIFYING HYDROCHLORIC ACID - Provided is a method of purifying hydrochloric acid by removing an organic substance having a boiling point of −25° C. to 120° C. under atmospheric pressure from an organic substance-containing hydrochloric acid that contains the organic substance and has a hydrogen chloride concentration higher than an azeotropic hydrogen chloride concentration under atmospheric pressure. The method includes the step of subjecting the organic substance-containing hydrochloric acid to distillation using a distillation tower at an operation pressure set such that an azeotropic hydrogen chloride concentration under the operation pressure is higher than the hydrogen chloride concentration of the organic substance-containing hydrochloric acid, to distill out the organic substance from the top of the distillation tower. | 09-29-2011 |

| 20120128518 | SCROLL COMPRESSOR - A scroll compressor includes a back pressure chamber oil-feeding path for feeding lubricating oil from a high-pressure region to a back pressure chamber, and a compression chamber oil-feeding path for feeding lubricating oil from the back pressure chamber to a compression chamber. One phase in which the back pressure chamber oil-feeding path is communicated from the high-pressure region to the back pressure chamber and another phase in which the compression chamber oil-feeding path is communicated from the back pressure chamber to the compression chamber are shifted from each other, so that the back pressure chamber oil-feeding path and the compression chamber oil-feeding path are never put into the communicating state simultaneously. Thus, after a halt of the compressor, under-communication oil-feeding of the lubricating oil from the high-pressure region via the back pressure chamber to the compression chamber can be prevented, so that the lubricating oil in the liquid storage section is kept from decreasing and moreover the lubricating oil is kept from being filled into the compression chamber, make it possible to achieve a stable restart-up. | 05-24-2012 |
