Title: Method and apparatus for colorimetric color expression and computer readable information-recording medium with colorimetric color expression program recorded
Inventor: IINO KOICHI
IPC: G01J3/52
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To dispense with a spectral characteristics measurement apparatus and simply, speedily and highly accurately display colorimetry values by obtaining a spectral characteristic of an illumination light from image data picked up from a standard plate, and converting the image data into colorimetry value image data. SOLUTION: A standard plate 1 set to a position to be measured in a space is picked up by an image pickup means 2 from a position of a measurement point in the space. Obtained image data is analyzed by an analysis means 3 on the basis of image characteristic data of the pickup means 2 and spectral reflectance data of surfaces of color chips of the standard plate 1. Spectral characteristic data of an illumination light of the position to be measured in the space is thus obtained. A conversion coefficient is calculated from the spectral characteristic and a spectral sensitivity characteristic of the image pickup means 2. Image data picked up by the image pickup means 2 is converted into colorimetry value image data with the use of the conversion coefficient.  The converted colorimetry value image data is further converted into image data for driving a display system, whereby the image is displayed. This display image is displayed by storing color information of the picked space colorimetrically, and therefore the image can be reproduced with the same color as a scene of the picked space.

Title: Tire with tube
Inventor: YAMAGIWA TOSHIO
IPC: B29C73/22
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To prevent a tube from being damaged when a sealant is filled, and to prevent an air valve of a tube from being clogged with the sealant. SOLUTION: Two tubes in which a sealant chamber 7 in which the sealant 8 is filled and an air chamber 3 in which air is filled are demarcated by partitioning the inside of a circumferential wall 4 of circular section by a bulkhead 5, are joined with each other on an outer surface of circumferential walls 4i of the air chamber, and fitted to the inner side of the tire 1. Even when the tube 2 is pierced by a nail, etc., the sealant 8 repairs the pierced part to prevent air leakage from the air chamber 3. Because no sealant capsule to be broken by the external force is used, the external force is unnecessarily applied to the tube 2 in filling the sealant 8, and the tube is prevented from being damaged. Because the air chamber 3 provided with an air valve 6 is isolated by a bulkhead 5 from the sealant chamber 7, the air valve 6 is not clogged with the sealant 8.
