Publication number: 20060152127Abstract: A display filter is provided that can realize price reduction without lowering electromagnetic wave shielding ability and near infrared rays shielding ability. A conductive mesh is used for shielding electromagnetic waves. A multilayered film and a coloring layer are used for shielding near infrared rays. The multilayered film reflects near infrared rays selectively and the coloring layer absorbs near infrared rays selectively. The use of the multilayered film significantly reduces near infrared rays absorption ability that is required for the coloring layer compared to the case where no multilayered film is used.Type: ApplicationFiled: September 29, 2005Publication date: July 13, 2006Applicant: FUJITSU HITACHI PLASMA DISPLAY LIMITEDInventors: Yoshimi Kawanami, Takatoshi Hirota, Nobuyuki Hori

Patent number: 6835119Abstract: A method for lapping which eliminates lapping damage includes a high-speed lapping operation at a high torque which is continuously performed after performing intermittently a low-speed lapping operation under low torque on a workpiece. Therefore, the excessive load during a first lapping stage due to the projection on the surface of the workpiece is greatly decreased. A continuous lapping is performed after the projection becomes smooth to some extent, and thus the lapping damage is prevented.Type: GrantFiled: February 27, 2004Date of Patent: December 28, 2004Assignee: Murata Manufacturing Co., Ltd.Inventor: Nobuyuki Hori

Patent number: 6775040Abstract: A scanning sync-signal detecting circuit for a laser scanner is provided. The circuit prevents misdetections of a horizontal sync signal caused by stray beams and enables a precise detection of the sync signal, independent of the beam power. The scanner comprises a laser detector and a sync-detecting circuit.
