Accordingly, the photographing step and the etching away step can be eliminated. Furthermore, the inside of the viahole 7 can take a taper shape thereby enabling the step coverage to be enhanced while avoiding the disconnection inside the viahole 7.

Title: Controller for arc length of arc welder
Inventor: MITSUSHIERU GEE DOROE
IPC: H05B7/144
Filed: 1984-04-04
Abstract: In accordance with the method, the arc supplying current is modulated if necessary for generating an acoustical signal. The acoustical signal generated by the arc is detected and its amplitude which, in practice, is a direct function of the actual length of the arc, is compared to a reference amplitude corresponding to the desired length of the electrical arc, in order to determine the algebraic value of their difference. This algebraic value is used for monitoring at least one element of the machine between which the arc forms, and moving this element proportionally to the so-determined algebraic value in order to increase or reduce the actual length of the arc and to bring this length back to the desired length.

Title: Image forming device and image forming method
Inventor: KANDA KIMIKATSU
IPC: H04N1/405
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To form an output image with high quality and high reproducibility with respect to an input image even in a low density area or a high density area. SOLUTION: An image forming device 10 is configured by interconnecting an original read section 18 and a write device 28 via a conversion section 28. The original read section 18 reads a density of a contract image for each pixel, quantizes the density into 256 gradations and outputs the result to the conversion section 58 as the input density. The conversion section 58 converts the input density into an output density such that the output density is linearly increased with respect to the input density and the output density is a 1st threshold value or over and a 2nd threshold value or below. Furthermore, a difference between the input density and the output density is distributed to vicinity pixels by an error diffusion method.  The write device 28 uses a pulse signal with a pulse width in response to the output density to drive a laser beam source, emits a laser beam to a photoreceptor drum 24 to form an electrostatic latent image. The electrostatic latent image is visualized by using toner, transferred onto recording paper, on which the contrast image is formed.
