Title: Turn ratio measuring method and its apparatus
Inventor: OZAKI EIJI
IPC: G01R29/20
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a turn ratio measuring method and its apparatus which can realize high measurement precision without generating errors, reduce the size and the weight of apparatus constitution and be automated. SOLUTION: Voltage variable power sources 11 and 12, and volt meters (voltage measuring means) 3 and 4 are connected with the primary side and the secondary side of a device 1 under test, respectively. Further an ammeter (current measuring means) 6 is connected with the secondary side. The voltages of the voltage variable power sources 11, 12 are controlled and the current flowing in the ammeter 6 is minimized. Since a current does not flow in the leakage impedance 7 in a circuit, an error voltage by the current is not generated. Thereby an accurate turn ratio V2/V1 is given by the transformation ratio obtained by voltages which are measured by the primary side voltmeter 3 and the secondary side volt meter 4.

Title: Color printing method and equipment for compensating abney effect
Inventor: BURIJITSUTO RUETSUTSU
IPC: B41J2/21
Filed: 1993-10-19
Abstract: PURPOSE: To compensate an Abney effect by warping the hue angle of a printer table. CONSTITUTION: Each transition color in the area between the edge section 60 of a printer color gamut and the edge section 61 of a printer table color gamut, which substantially matches with the edge section of a typical color monitor is selected against the transition colors of the colors on the edge section 60 at a fixed angle αfrom the transition colors. In this case, any kind of variation of luminance is permissible, because a luminance varying extent is not limited to an arbitrary threshold. For example, a point 64 on the edge section 60 is selected to a transition color 62, because the point 64 is at the angle αfrom the point 62. As a point 65, a pertinent point which is at the angle αact as a point 66 is selected on the edge section 60 with respect to each point in a transition area such as a point 65.  For a transition color exceeding the maximum saturation point 67, the angle α is taken downward. By warping (distorting) the hue of the colors on the outside of the color gamut, the color curve of an Abney effect can be compensated.
