  • Patent number: 9726405
    Abstract: An ejector includes a first nozzle, a second nozzle, an atomization mechanism, and a mixer. A working fluid in a liquid phase is supplied to the first nozzle as a drive flow. A working fluid in a gas phase is sucked into the second nozzle. The atomization mechanism is disposed at an end of the first nozzle and atomizes the working fluid in a liquid phase while maintaining the liquid phase. The mixer generates a fluid mixture by mixing the atomized working fluid generated by the atomization mechanism and the working fluid in a gas phase sucked into the second nozzle. The atomization mechanism includes an ejection section that generates a jet of the working fluid in a liquid phase and a collision surface with which the jet from the ejection section collides. The collision surface is inclined with respect to a direction in which the jet flows.

  • Publication number: 20150114017
    Abstract: The disclosed refrigeration-cycle equipment comprises a main circuit and an evaporation-side circulation circuit. The main circuit includes i) a compressor that compresses refrigerant vapor, ii) a condensation mechanism that condenses the refrigerant vapor, and iii) an evaporative mechanism that stores refrigerant liquid and that evaporates the refrigerant liquid. The evaporation-side circulation circuit includes a heat exchanger for heat absorption and a decompression mechanism. The refrigerant returns to the evaporative mechanism after the refrigerant absorbing heat in the heat exchanger for heat absorption and the pressure of the refrigerant being reduced in the decompression mechanism. The refrigeration-cycle equipment further has an interaction mechanism that prevents droplets contained in the refrigerant having returned from the evaporation-side circulation circuit to the evaporative mechanism from being fed into the compressor.

  • Patent number: 9019294
    Abstract: A first table, which expresses a color reproducible characteristic of a first output device, is generated, and a second table, which expresses a color reproducible characteristic of a second output device, is generated. Color values of grid points of the first table are mapped to a color gamut of the second output device expressed by the second table. A third table, which expresses a relationship between color values of the first table after mapping processing and device values required to reproduce colors of the color values by the second output device, is generated. With reference to the third table, a profile, which expresses a relationship between color values of grid points arranged on a uniform color space, and device values required to reproduce colors of the color values by the second output device, is generated.

  • Patent number: 8421817
    Abstract: In order to obtain a highly accurate color processing condition, a user is allowed to easily adjust a weight for a patch image with poor reliability. Hence, a color processing apparatus inputs color data of a plurality of patches included in a color chart captured by an image sensing device. Patch images based on the color data are displayed on a monitor, and a user interface for inputting a user's instruction to adjust a weight value for each patch image is displayed on a monitor. A color processing condition of an image captured by the image sensing device is generated based on the weight value, the color data, and a target value of a color representation corresponding to each patch image.

  • Patent number: 7844109
    Abstract: In order to allow a user to arbitrarily set color processing parameters which determine the color reproduction characteristics of a digital camera according to user's preference, an image processing unit obtains color data by performing the same processing as that performed by the digital camera with respect to the sensed data of each color patch included in a color chart by using color processing parameters. A changing unit displays, on a display unit, a target data changing window which presents color data and the target data (the target color of color reproduction) of each color patch and allows the user to change the target data. A parameter editing unit edits color processing parameters so as to reduce the color difference between the changed target data and color data. A data input/output unit transmits the edited color processing parameters to the digital camera.
