Title: Natural lighting device
Inventor: KODAIRA TAKASHI
IPC: G02B27/00
Filed: 1990-11-22
Abstract: PURPOSE:To effectively introduce incident light as diffracted light even in case when the incident angle is varied with time by arranging diffraction grating formed with a plurality of annular grating grooves on a natural lighting part. CONSTITUTION:Transmission type diffraction grating 13 having a plurality of annular grooves is arranged on a natural lighting part 12 for introducing light. The diffraction grating 13 formed with a plurality of annular grooves of concentric circles or ellipses on the transparent plate has a property to improve lighting efficiency as a whole, by dispersing the light not facing to the center but gathering much light facing to the center. Whichever direction the light source is, the diffracted light in the center direction is always available and as a whole much diffracted light is supplied to light introducing duct sides 17, 20. Hereby, even when the incident angle such as that of the solar ray is varied, effective lighting can be performed.

Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of the performance of an infrared ray detector by capturing the outgas and contaminant generated by a artificial satellite itself by a cold trap, and preventing the invasion of the contaminant from an external to the artificial satellite by the cold trap. SOLUTION: When a heating state of a baking heater is stopped, and an infrared ray detector 11 starts its operation again, the outgas is attached to the cooled infrared ray detector 11 with a lapse of time. On this occasion, the outgas which is generated in the overheating by the baking heater, and is not discharged to an external, is actively adsorbed by the cold trap 31 cooled by a radiational cooling plate 32. Further the contaminant counter-flowed from an exhaust port 34 can be also adsorbed by the cold trap 31. According the outgas and the contaminant adsorbed by the cold trap 31 are kept at a low temperature at all times, so that the scattering thereof can be prevented.

Abstract: PROBLEM TO BE SOLVED: To provide a color correction method of image data where a color of an image is changed without causing a sense of incongruity to the user and to provide a digital camera that executes the color correction method. SOLUTION: After converting color data of a planar chromaticity coordinate system obtained from image data are converted into color data of a chromaticity coordinate system approximated to a human perception characteristic, correction loci T, T' tying the converted color data and an object value in the coordinate system are calculated. Based on the correction loci, a color of the image data is changed. The color of the image data is changed based on the correction loci in the chromaticity coordinate system approximated to the human perception characteristic and then the user can sense a change in the color in a degree the same as a degree of the change.
