  • Patent number: 7911515
    Abstract: Calculation is made about standard deviations of portions of high-frequency components GH, RH, and BH along respective predetermined directions. The portions of the high-frequency components GH, RH, and BH represent a prescribed number of pixels including an interpolation pixel located at a position corresponding to none of photosensor pixels in G, R, and B image sensors. The smallest one is detected among the calculated standard deviations. The predetermined direction relating to the detected smallest standard deviation is labeled as a highest-correlation direction in which the highest correlation occurs. Interpolation is implemented in response to portions of the high-frequency components GH, RH, and BH which correspond to the highest-correlation direction to generate a high-frequency interpolation-result signal RGBHI for the interpolation pixel and other pixels.

  • Patent number: 7785542
    Abstract: A hydrogen iodide manufacturing method which includes a step of producing aqueous solution of hydrogen iodide and sulfuric acid by causing iodine-containing aqueous solution and sulfur dioxide to react with each other in a pressurized condition. The pressurized condition may be of not lower than 0.1 MPa in gauge pressure. The method may further include: a separation step of adding iodine to the aqueous solution of hydrogen iodide and separating an upper phase containing sulfuric acid relatively to a large extent and a lower phase containing hydrogen iodide relatively to a large extent; and a step of producing hydrogen iodide by adding sulfur dioxide to the upper phase in a pressurized condition and extracting the produced hydrogen iodide to the lower phase.

  • Patent number: 7722346
    Abstract: A method of supplying lubrication oil to a two-stage screw compressor is disclosed in which a low-pressure stage screw compressor and a high-pressure stage screw compressor are integrally constructed. A compression space is formed by a male rotor and a female rotor, and operation gas is fed for compression to the compression space. The method prevents degradation of volumetric efficiency caused by return of lubrication oil, coming from a bearing and a shaft sealing device, to the low-pressure stage screw compressor, and as a result, refrigeration capacity is improved and the amount of the lubrication oil is reduced.

  • Publication number: 20080059666
    Abstract: A microcontroller has a RAM monitor function that facilitates debugging by enabling a debugging device to specify a location and access the specified location during program execution. Access takes place when the microcontroller's central processing unit or a peripheral module in the microcontroller satisfies a predetermined condition. The access can therefore be synchronized with the execution of a particular instruction, or the occurrence of an interrupt.

  • Publication number: 20070014790
    Abstract: To determine the biological role of ZHX1, found previously, which acts as a transcriptional repressor, the inventors conducted a search of ZHX1—interacting proteins using a yeast two-hybrid system. Molecular cloning and determination of the nucleotide sequence of the full-length cDNA encoding a novel protein revealed a novel protein with SEQ ID NO: 1. The protein (ZHX3), like ZHX1, contains two zinc-finger (Znf) motifs and five homeodomains (HDs) and has a transcriptional repressor activity.
