Publication number: 20070243409Abstract: To solve problems of a conventional process for producing a ceramic sheet by extrusion such that it is a production process with a prolonged lead time requiring material granulation and homogenization steps and if homogenization of a kneaded clay is insufficient, the dispersion of the density of a green sheet will occur and a ceramic sintered body after firing will have deformation or warpage, thereby to cause failures in circuit pattern printing and joining between a metal circuit board and a heatsink. A process for producing a ceramic sheet comprising use of an extrusion molding machine combining a twin screw extruder with powerful kneading performance and a single screw extruder with molding stability, so that a quality equivalent to or superior to that of the prior art can be obtained and that high production efficiency can be attained, and a ceramic substrate utilizing it, are obtained.Type: ApplicationFiled: March 17, 2005Publication date: October 18, 2007Applicant: Denki Kagaku Kogyo Kabushiki KaishaInventors: Ryou Terao, Makoto Fukuda, Nobuyuki Yoshino

Patent number: 6511156Abstract: A nozzle plate for an ink-jet head used in an ink-jet type recorder, comprising a flat plate member which defines an ink blow-out surface on one main surface thereof and has a plurality of ink blow-out nozzles penetrating at predetermined positions, wherein said ink blow-out surface and portions on the inner surfaces of said ink blow-out nozzles neighboring said ink blow-out surface, have, at least partly, an ink-repelling layer of a fluorine-contained resin-containing electrolytic or non-electrolytic composite plating. Upon forming a particular ink-repelling layer on the nozzle plate, it is possible to prevent the ink from staying adhered on the peripheries of the nozzles after the ink droplets are blown out from the nozzles, permitting the ink droplets to fly stably toward the recording medium.Type: GrantFiled: December 17, 1999Date of Patent: January 28, 2003Assignee: Citizen Watch Co., Ltd.Inventors: Ayako Kazama, Nobuyuki Yoshino, Yorinobu Yamada, Isao Mizuma

Patent number: 6425793Abstract: An impregnated cathode and a method of manufacturing the same are provided for suppressing emission of unwanted electrons and particles generated from an excess electron emitting substance so as to achieve a steady electron emission characteristic. The impregnated cathode is placed directly beneath an electron emission hole of a first grid. The impregnated cathode is made up of a first sintered porous element whose surface functions as an electron emitting region and a second sintered porous element whose surface is a peripheral region other than the electron emitting region. The porosity of the first sintered porous element is greater than that of the second sintered porous element. Not only the first sintered porous element having the electron emitting region but also the second sintered porous element corresponding to the region around the electron emitting region is impregnated with the electron emitting substance.Type: GrantFiled: September 28, 2000Date of Patent: July 30, 2002Assignees: Sony Corporation, Citizen Watch Co., Ltd., Cimeo Precision Co., Ltd.Inventors: Yoji Hasegawa, Shinji Ogawa, Daichi Imabayashi, Makoto Furukawa, Nobuyuki Yoshino, Junji Sato, Yoshirou Hirai, Naoto Ogasawara, Kuniyasu Kobayashi

Patent number: 5642632Abstract: In knitting parts (a jacquard guide needle, a guide, a needle, a tongue, a sinker, a separator, etc.), each having a portion which is brought into contact with a knitting yarn when fitted to a knitting machine to perform knitting, the surface of a portion of a metallic part base material (10) thereof is coated with a compound plating layer (12) made of a non-electrolytic nickel alloy plating layer including minute silicon particles dispersed therein, each of the silicon particles being coated with a hard carbon film. As a result, it is possible to improve the durability of the knitting parts similarly to those in which the surface of the part base material is coated with the hard carbon film and moreover remarkably reduce the processing cost.Type: GrantFiled: August 11, 1995Date of Patent: July 1, 1997Assignee: Citizen Watch Co., Ltd.Inventors: Takanori Nanya, Nobuyuki Yoshino
