Patent number: 7011920Abstract: A non-magnetic mono-component toner of the present invention is composed of a coloring powder at least containing a binder resin, coloring agent and wax and at least one kind of external additive having a mean particle diameter of 0.04 ?m or greater, wherein the relationship between the Vickers hardness of the above coloring powder and the mean particle diameter of the external additives satisfies the predetermined expression. Thereby, the present invention is effective in preventing the external additive particles from sinking into the toner surface as well as from falling off from the surface when the toner particles are stressed in the developing unit. As a result, it is possible to provide stable image quality free from degradation of toner charge performance and toner supply performance even for long-term use.Type: GrantFiled: November 12, 2003Date of Patent: March 14, 2006Assignee: Sharp Kabushiki KaishaInventors: Takafumi Nagai, Tadayuki Sawai, Toshihisa Ishida, Kouji Kida, Kazuya Korematsu, Toru Nishikawa, Yoshimi Kojima

Patent number: 5973406Abstract: An electronic device is solder bonded properly without using fluxes nor precise positioning with respect to a substrate. A bond pad with a size about twice the size of terminal pad of the electronic device is formed in a region on the substrate where the electronic device is to be mounted. After placing the electronic device of the substrate surface, the whole unit is heated in a nitrogen atmosphere to melt a bump formed on the terminal pad of the electronic device. The molten solder wets and spreads over the bond pads formed on the substrate, thereby establishing reflow soldering between the bond pads and the terminal pads. The position of the electronic device with respect to the substrate is spontaneously corrected due to a self-alignment function induced by wetting and spreading of the molten solder over the bond pad of the substrate.Type: GrantFiled: August 25, 1997Date of Patent: October 26, 1999Assignee: Hitachi, Ltd.Inventors: Masahide Harada, Toru Nishikawa, Ryohei Satoh, Osamu Yamada, Takayuki Uda, Mitsugu Shirai
