Patent number: 6440501Abstract: An apparatus for curing silicone rubber is constructed so as to perform a heating process and a curing process in a very short time without degradation of characteristics in piezoelectric elements so as to improve productivity. A piezoelectric component having uncured silicone rubber coated on the external peripheral surface thereof is held in a jig having a property of reflecting far infrared rays. The uncured silicone rubber coated on the external peripheral surface of the piezoelectric component is irradiated with far infrared rays by a far infrared panel heater so as to cure the silicone rubber.Type: GrantFiled: December 28, 2000Date of Patent: August 27, 2002Assignee: Murata Manufacturing Co., Ltd.Inventor: Masanobu Sugimori

Publication number: 20020098364Abstract: A method for fabricating silicone elastomer stamps with hydrophilic surfaces is provided. The concept of polymer grafting is used to produce the stamps. The stamps thus produced have the great advantage that grafting of a thin hydrophilic polymer on a hydrophobic PDMS surface can render PDMS stamps permanently hydrophilic. With such stamps it becomes possible to print aqueous or highly polar inks reproducibly over days and weeks.Type: ApplicationFiled: September 14, 2001Publication date: July 25, 2002Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Andre Bernard, Emmanuel Delamarche, Christian Donzel, Jons Gunner Hilborn, Bruno Michel, Richard Stutz, Heiko Wolf

Patent number: 6423378Abstract: The invention concerns the use of cross-linkable silicone compositions for fast, economical and simple impregnation and/or varnishing of flat joints (e.g. cylinder head gaskets). More precisely it concerns the use of silicone compositions cross-linkable under UV radiation, by cationic process and in the presence of specific phoinitiators selected among onium borates or organometallic complexes, of which the borate counter-anions contain at least a boron bound to at least a substituted phenyl (Me, F). The silicone liquid precursor is a polydimethylsiloxane (PDMS) substituted by cross-linking functional groups, by cationic process (Gfp) under UV of the epoxy of vinyloxy type. These Gfp are present at the rate of 0.15 to 2.0 pr kg of PDMS. The invention also relates to the method for impregnating/varnishing flat joints (e.g. cylinder head gaskets) using the specific PDMS composition+photoinitiator of borate type as well as the treated joints and the composition themselves.Type: GrantFiled: August 30, 1999Date of Patent: July 23, 2002Assignee: Rhodia ChimieInventors: Marie-Christine Cotting, Gérard Joubert, Olivier Loubet

Patent number: 6406758Abstract: A method of applying a protective coating to a touch screen panel. A coating material which cures at an elevated temperature is applied to a touch screen panel on at least one surface thereof. The panel is then heated to a temperature which does not adversely affect the panel by irradiating the panel imparting energy to the coating material to more fully cure the coating material in a shorter time period without damaging the panel.Type: GrantFiled: July 25, 2000Date of Patent: June 18, 2002Assignee: 3M Innovative Properties CompanyInventors: Frank J. Bottari, Paul J. Richter, Chia-Yen Li
