Abstract: PURPOSE:To accurately reproduce a color under an arbitrary light source by using the color value obtained from the spectral distribution of illumination for observation and the color value corresponding to a prescribed light source to convert the color to the device value of a color output device. CONSTITUTION:A spectro photometric-colorimetric instrument 7 sends a spectral distribution signal 8 of the illuminating light source for observation to a color value calculating computer 1. The computer 1 calculates a color value signal 2 corresponding to the illuminating light source for observation and sends it to a color conversion means 4. The computer 1 sends a color value signal 3, which is preliminarily registered and corresponds to a prescribed light source like a D light source, to the color conversion means 4. This means 4 consists of a feed forward neutral network with the learning function and used color value signals 2 and 3 to correct a device value signal 6 of RGB or the like and sends it to a color output device 5. Thus, the color output device 5 reproduces the picture whose color under the illuminating light source for observation looks to be equal to that under the prescribed light source.

Title: Bias controlling device
Inventor: YOSHIMIZU MAKOTO
IPC: G11B5/03
Filed: 1984-11-14
Abstract: PURPOSE:To prevent destruction of a voltage control amplifier or while of a bias controlling device in the bias controlling device in which output of the voltage control amplifier is applied superposing on recording signals to a recording head by connecting a limiter to the voltage control amplifier. CONSTITUTION:In a normal state, current that flows in the recording head 1 is detected by a low-pass filter 4, and the quantity of effective bias is detected by a peak detector 5. The quantity of effective bias is compared with voltage of a reference voltage source 9 by a comparator 6, and output of the comparator 6 controls gain of the voltage control amplifier 10 to keep the quantity of effective bias constant. Output of the voltage control amplifier 10 is superposed on signal current applied from a signal input terminal 13 by an adder 14 and applied to the recording head 1. In the case where gain control of the voltage control amplifier 10 becomes impossible due to, for instance, the grounding of the inputting section of the peak detector 5, the generation of excessive output of the voltage control amplifier 10 is prevented by the limiter 17.

Title: Control method for generation of sculptured surface
Inventor: MAKINO HIROSHI
IPC: G05B19/4097
Filed: 1989-09-18
Abstract: PURPOSE:To attain the real time control of a device by replacing a clothoid curve with an expression of a differential form so as to obtain the coordinates of the clothoid curve at an extremely high speed when a sculptured surface curve is generated. CONSTITUTION:A clothoid curve having the length S covering a point P0 through a point Pn is divided into (n) pieces of segments having the length DELTAS. These segments DELTAS have the same length. Then the circular arcs P0P1, P1P2... are approximated by a straight line P0P1P1P2... and combined with the angles phi2 of each dividing point. Thus the clothoid curve is replaced with an expression of a differential form. In terms of the control method for generation of sculptured a surface, the calculation of the initial value includes the calculations of the cos and sin functions in a calculation process. Other functions, however, are calculated with the addition and the multiplication only. Thus the coordinates of the clothoid curve are obtained at an extremely high speed when the sculptured surface is generated with use of the clothoid curve. Then the real time control of the device is attained.
