IPC: H03L1/02
Filed: 2002-08-05
Abstract: <P>PROBLEM TO BE SOLVED: To eliminate a temperature change of an oscillation frequency, to make consumption current in an oscillation circuit to be low and to prevent a frequency adjusting circuit from being easily affected by fluctuation of power voltage of the oscillation frequency.  <P>SOLUTION: An adjusting means of the oscillation frequency has adjustment of the oscillation circuit itself 10 and adjustment by a frequency dividing circuit 12. A frequency adjusting circuit 16 is used for adjusting oscillation frequency dispersion by the oscillation circuit 10 and dispersion of a quartz vibrator (piezoelectric vibrator) itself 11, and a frequency adjusting circuit 17 is used for correcting the oscillation frequency. Thus, an output frequency of the oscillation circuit 11 can be adjusted. Timing signals 1 and 2 are outputted from a control circuit 14 to an A/D converter 22 and a temperature sensor 23. Consequently, they are operated by prescribed time and the frequency is adjusted. Thus, wasteful power can be avoided.  <P>COPYRIGHT: (C)2004,JPO

Title: Gravure platemaking method
Inventor: SHIGETA TATSUO
IPC: B41C1/04
Filed: 2002-08-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide a gravure platemakimg method, in which a gravure plate produced by adding screen ruling to an FM (frequency modulation) screen is easily, quickly and favorably obtained without developing pin hole.  <P>SOLUTION: A negative mask is formed by coating by jetting ink having resistance to etching liquid from an inkjet nozzle through the scanning action of the inkjet nozzle. After the formation of the negative mask, cells are formed by etching. The negative mask is formed by coating on the basis of the digital information obtained through an improved FM screening. In the improved FM screening, the reference dots are set to have a size, under which the ink is favorably transferred from a cell, and closed up in response to shading gradient so as to perform the dot transformation of the image in a highlight part and in a halftone part. As for the dot transformation of the image in a shadowy part, the dot transformation is performed by gradually narrowing the width of the non-image part of a dot smaller than the reference dot in response to its shading gradation so as to remain the screen ruling in order to bear a doctor blade.  <P>COPYRIGHT: (C)2004,JPO
