Publication number: 20110008071Abstract: Provided is a full color image forming method wherein high color reproducibility especially on a blue system and a green system can be obtained and an excellent gradation property can be obtained in a full color image to be obtained. The full color image forming method for forming a full color image by using at least yellow toner, magenta toner, and two kinds of cyan toners (1, 2) is characterized in that a toner image formed by the cyan toner (1) alone has the value of the maximum color saturation (C*) of not less than 50 and the value of lightness (L*) in a color space represented by an L*a*b* colorimetric system of not less than 30 and not more than 52, and that a toner image formed by the cyan toner (2) alone has the value of the maximum color saturation (C*) of not less than 50 and the value of the lightness (L*) in the color space represented by the L*a*b* calorimetric system of not less than 58 and not more than 75.Type: ApplicationFiled: July 13, 2009Publication date: January 13, 2011Applicant: KONICA MINOLTA BUSINESS TECHNOLOGIES, INC.Inventors: Shiro Hirano, Naohiro Hirose, Kaori Soeda, Miyuki Murakami, Youhei Ohno

Patent number: 7847318Abstract: Mesh holes 35a and 59a of upper solid layers 35 and upper solid layers 59 are formed to overlie on one another, so that the insulating properties of interlayer resin insulating layers 50 are not lowered. Here, the diameter of each mesh hole is preferably 75 to 300 ?m. The reason is as follows. If the diameter of the mesh hole is less than 75 ?m, it is difficult to overlay the upper and lower mesh holes on one another. If the diameter exceeds 300 ?m, the insulating properties of the interlayer resin insulating layers deteriorate. In addition, the distance between the mesh holes is preferably 100 to 2000 ?m. The reason is as follows. If the distance is less than 100 ?m, the solid layer cannot function. If the distance exceeds 2000 ?m, the deterioration of the insulating properties of the interlayer resin insulating film occurs.Type: GrantFiled: March 17, 2009Date of Patent: December 7, 2010Assignee: IBIDEN Co., Ltd.Inventors: Naohiro Hirose, Honjin En

Patent number: 7832098Abstract: An opening is formed in resin 20 by a laser beam so that a via hole is formed. At this time, copper foil 22, the thickness of which is reduced (to 3 ?m) by performing etching to lower the thermal conductivity is used as a conformal mask. Therefore, an opening 20a can be formed in the resin 20 if the number of irradiation of pulse-shape laser beam is reduced. Therefore, occurrence of undercut of the resin 20 which forms an interlayer insulating resin layer can be prevented. Thus, the reliability of the connection of the via holes can be improved.Type: GrantFiled: April 7, 2008Date of Patent: November 16, 2010Assignee: IBIDEN Co., Ltd.Inventors: Naohiro Hirose, Kouta Noda, Hiroshi Segawa, Honjin En, Kiyotaka Tsukada, Naoto Ishida, Kouji Asano, Atsushi Shouda

Publication number: 20090173523Abstract: Mesh holes 35a and 59a of upper solid layers 35 and upper solid layers 59 are formed to overlie on one another, so that the insulating properties of interlayer resin insulating layers 50 are not lowered. Here, the diameter of each mesh hole is preferably 75 to 300 ?m. The reason is as follows. If the diameter of the mesh hole is less than 75 ?m, it is difficult to overlay the upper and lower mesh holes on one another. If the diameter exceeds 300 ?m, the insulating properties of the interlayer resin insulating layers deteriorate. In addition, the distance between the mesh holes is preferably 100 to 2000 ?m. The reason is as follows. If the distance is less than 100 ?m, the solid layer cannot function.
