Publication number: 20080145578Abstract: The present invention relates to a decoration technique for providing iridescent color effects or glittering luster effects to a resin casing by attaching a polarizing film in contact with a resin casing, and for finishing a cut-off edge portion of the polarizing film smooth. After forming the polarizing film on a mold having a prescribed shape, a thermoplastic resin is injected into the mold to produce a thermoplastic resin casing to which the polarizing film is firmly attached. When cutting off an excess portion of the polarizing film by using a cutting die, a heater built into the cutting die is energized, and the cut-off edge portion of the polarizing film is fused by the heating of the cutting die, thus fixing the edge portion to the thermoplastic resin.Type: ApplicationFiled: June 18, 2007Publication date: June 19, 2008Applicant: FUJITSU COMPONENT LIMITEDInventors: Takashi Yuba, Shinichiro Akieda, Takashi Arita

Patent number: 7242395Abstract: An input device and a driving device able to be made thin and secure sufficiently large vibration amplitude are provided. The input device comprises an input panel, a current conducting element for conducting a driving current, and a magnetic field application unit for applying a magnetic field on the current conducting element. Both of the current conducting element and the magnetic field application unit are arranged in the peripheral region of the input panel. The magnetic field applied by the magnetic field application unit is parallel to the input panel and intersects the current conducting element. When the input panel is touched, a driving current is fed into the current conducting element, and a force is imposed on the current conducting element and the magnetic field application unit, making them move. This movement further drives the input panel to vibrate. Consequently, input operations can be recognized by feeling the vibration of the input panel.Type: GrantFiled: October 3, 2003Date of Patent: July 10, 2007Assignee: Fujitsu Component LimitedInventors: Shigemi Kurashima, Nobuyoshi Shimizu, Akio Nakamura, Yuriko Nishiyama, Shinichiro Akieda, Takashi Arita

Publication number: 20060109254Abstract: A haptic panel apparatus is disclosed that enables an operator to sense movement of a touch panel through touch when an input is made. The touch panel is accommodated within a base member, and an electromagnetic drive mechanism is provided between the touch panel and the base member. When the operator operates the touch panel with his/her fingertip and an input is made, the electromagnetic drive mechanism is driven to induce the touch panel to recede.
