Abstract: In a method for mutual transformation between the data of a light-source color on a color CRT monitor and the data of a non-luminous object color perceived as matching with the light-source color, the transformation can be performed by using any of the following two formulas: 
R C (λ) = [I C (λ)/I G (λ)]R G (λ); 
and      wherein: 
Both R C (λ), and X, Y and Z express the non-luminous object color data which are designated at a spectral reflectance factor and the CIE tristimulas values, respectively; and 
Both I C (λ), and R C , G C  and B C  express the light-source color data, which are designated at a spectral distribution and the RGB video drive signals, respectively. 
Unknown parameters R G (λ) and I G (λ) and k R , k G  and k B , which are used in the two formulas above, are determined by visual color matching under the Color Comparison Condition in which the light-source color on the color CRT monitor and the non-luminous object color are placed side by side so that they may be simultaneously observed. 
A color comparator system for use in the method is also provided.

Abstract: The subject of the present invention is hydraulic reels with a replaceable spool for a fishing line. The technical field of the invention is that of the manufacture of a hydraulic reel, and the principal application of the invention is for deep-sea fishing using a line dragged along by a boat. A hydraulic reel system (2) comprises a supply regulated by a pump (10), with a constant pressure which can be adjusted, which can be read on a manometer (4) and which has a variable output. The system drives a spool (1) of fishing line (7) by a coupling (5) which can be disengaged from an end plate (18) of the said spool. The other end plate (18) drives a pulley (19) by a coupling which is likewise disengageable and moveable (5'), permitting the complete disengagement of the spool (1) which can thus be removed and replaced quickly by a new one. A line guide (8) ensures the correct winding of the line (7) onto the spool. <IMAGE>

Abstract: A recirculating filter system is provided for a sealed magnetic disk drive by providing a cartridge housing that mounts a filter medium closely adjoining the disk stack and substantially concentric therewith. The frame (39) that mounts the filter medium (37) also serves as a baffle or diverter to deflect air impelled by rotation of the disks to the rear of the filter medium. The remaining sides of the housing contact the cover or enclosure to define a dead box behind the filter medium wherein the velocity head of the air flow is converted to a potential head. Air impelled along the surface of the medium, at the side confronting the disk stack, provides some aspiration. A plenum formed at the radial outward side of the filter medium enables effective use of the entire medium surface. The recirculating air filter cartridge is not only compact within a corner of the cover or enclosure, but also is easily manufactured as a result of the simple filter medium configuration.

Abstract: In a magnetically recording disk system according to the present invention, during rotation of the disk which generates a higher air pressure (n atm.) at the gap between the slider supporting a head thereon and the disk surface than the ambient air pressure so as to float the slider from the disk surface, a partial pressure of a vapor recalcitrantly released, by heat of the operation of the disk, from an organic material, such as silicone, constituting the recording disk system, is kept lower than 1/n of saturated vapor pressure of the released material. The head slider may be provided with a heater to heat the slider during the disk rotation warmer than the ambient air temperature, preferably by 3 to 15 °C higher at the air gap, so that the saturated vapor pressure can be higher at the air gap than without the heating. An enclosure containing the disk, the head/slider and other constituent members is preferably provided with ventilation holes, a first one on which is provided on a side radial to the disk, and a second one on a side axial to the disk, so that the released vapor is exhausted by radial air flow caused from the disk rotation. There is no head crash resulted from a deposition of vapor recalcitrantly released from silicone, on a slider surface facing the disk; accordingly, highly reliable magnetic disk system of enhanced recording density is achieved owing to decreased air gap.
