Patent number: 7806972Abstract: The object of the invention is to provide an oil ink set capable of obtaining images having high color reproduction capabilities and high color saturation in particular. The oil ink set of the invention comprises a firsts a second, and a third oil ink having a wavelength region in which the reflectivity of each oil ink on a recording medium changes from 80% to 5% in the wavelength range of 400 nm to 700 nm. In this wavelength region, the reflectivity of the first oil ink is continuously higher than that of the first oil ink, and in the wavelength in which the reflectivity of the second oil ink changes from 80% to 5%, the reflectivity of the third oil ink is continuously higher than that of the second oil ink. Moreover, the coloring materials in the first, the second and the third oil inks are all different.Type: GrantFiled: March 24, 2009Date of Patent: October 5, 2010Assignee: The Intec Inc.Inventors: Yukio Sugita, Mitsuyoshi Tamura, Fumie Yamazaki, Mitsuteru Yamada, Naoki Shiraishi

Patent number: 6141847Abstract: A ceramic substrate 1 made of magnetic substance on which an inductor 2 is formed is prepared. A ceramic substrate 3 made of dielectric substance on which a capacitor 4 is formed is also prepared. An intermediate layer 5 made of lass paste is printed on the inductor 2 and the capacitor 4. After debinding the substrates 1 and 3 independently, both the substrates are filed with the intermediate layer 5 therebetween so that both the substrates may be glued and integrated. As such, because the debinding process is provided before filing, less gas is generated in firing, and as a result, voids are restrained from occurring.Type: GrantFiled: December 23, 1997Date of Patent: November 7, 2000Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masayuki Mizuno, Masaaki Hayama, Kazuhiro Miura, Noboru Mori, Akira Hashimoto, Mitsuteru Yamada
