Patent JP-H10319228-A (JP)
Title: Color filter, manufacturing method thereof and manufacturing device thereof
Inventor: ISHIMARU NAOHIKO
IPC: G02F1/1335
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To perform difficult color adjustment simply and stably and to improve uniformity of coloring while making the best use of mass productivity of an ink-jet mode and utility of ink by changing a driving condition to each ink-jet nozzle so that absorbance difference is within a predetermined value, and discharging the ink. SOLUTION: Ink discharge (1) is performed and an absorbance D1 of a first monochromatic picture element is measured (2). Following that, an absorbance D2 of a second monochromatic picture element discharging another ink is measured (3). The difference between the two absorbances ΔD=|D1 -D2 | is obtained (4). It is judged whether the difference ΔD between the two absorbances is within a predetermined value (5), and if ΔD is within the value, the processing goes back to the ink discharge (1), and if not, the ink-jet driving condition is changed (6), and then, the processing returns to the ink discharge (1). To be specific, the change in the ink-jet driving condition in this case is to change a voltage and pulse width for driving an ink-jet head and adjust an ink discharge volume for each nozzle.

Title: Magneto-optical recording device
Inventor: WATANABE SATORU
IPC: G11B11/10
Filed: 1988-05-30
Abstract: PURPOSE:To correctly form a recording pattern even when position dislocation is generated in a driving current by comparing the driving current of a magnetic head and the phase of a clock signal and correcting the phase of the driving current of the magnetic head on the basis of a compared result. CONSTITUTION:The driving current to be generated on the basis of the arbitrary clock signal is impressed to a magnetic head 6 and an alternative current magnetic field is generated. Then, this magnetic field is impressed to a magneto- optical head 4 and a position, to which the magnetic field is impressed, is radiated with a pulse-shaped laser light which is emitted on the basis of the clock signal. In such a case, a driving current IDV and the phase of a clock signal SCK are compared in a magnetic head driving circuit 21. Since the phase of the driving current IDV is corrected on the basis of the compared current, phase relation can be kept constant between an alternative current magnetic field HWI of the magnetic head 6 and a pulse-shaped laser light LPW. Accordingly, even when the position dislocation is generated in the driving current IDV by the change of an external temperature environment, etc., the recording pattern can be correctly formed on the magneto-optical disk 4.
