IPC: G01J3/46
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To decide a hue difference coincident with a result of a visual decision to obtain a decision result having objective reproducibility by obtaining a hue difference of a color to be decided from a reference color by a specific formula. SOLUTION: A distance between both a comparison color (color to be decided) and a reference color in color spaces is accurately obtained from hue difference of three attributes, and the hue difference is obtained. That is, the hue difference ΔH between the color to be decided and the reference color is obtained by the formula, wherein H1 is a hue of the reference color, C1 is a saturation and H2 is the hue of the color to be decided by a method for displaying a color by three attributes of the hue, the saturation and a lightness, and the hue difference of the color to be decided from the reference color is decided. Thus, a distance between the color to be decided and the reference color in a color space can be accurately obtained. Accordingly, a result of a visual decision and a coinciding decision result can be obtained objectively as a decision result with reproducibility.

Title: Clutch construction for wheel train of timepiece
Inventor: IKEDA HITOSHI
IPC: G04B27/00
Filed: 1985-03-15
Abstract: PURPOSE:To reduce cost by coupling a gear communicating with a time display wheel train and pinion by a magnet, etc. and releasing the coupling by an operating member in the stage of hand setting. CONSTITUTION:The operating member 2 is cooperatively moved and is positioned by an angle part 2c when an external operating member 1 is pulled by one step. The gear 4a is pushed upward in the axial direction of a transmission wheel, by which the magnetical coupling of the wheel 4a and the magnet 10 is released. The pinion 1b formed to the top end of the member 1 is meshed with a minute wheel 5. When the member 1 is rotated further, the wheel 5 is rotated and an hour wheel 7 and a center wheel 6 are rotated. The rotation of the wheel 6 is transmitted to the pinion 4b and the magnet 10 but the gear 4a is not coupled to the magnet 10 and is therefore not rotated. A second wheel 8 is not rotated. The cost of production is thus reduced and the reliability is improved.
