Publication number: 20090185340Abstract: The invention provides a casing structure for an electronic apparatus that achieves a thin size and light weight. The casing structure is capable of accommodating a display module, and comprises a sidewall and a bottom surface in which a conductive resin region and a nonconductive resin region are butt joined in a curved line. The casing structure of the electronic apparatus does not become thick due to the butt joining even when the joint portions are in a projection area of the display module. Furthermore, on the display side of the casing structure, there is no need to have special frame members for securing strength in addition to the display casing. The display casing accommodates and protects the display module from an external pressing force and also has a design function that the outer surface of the casing resembles that of an outer surface of a conventional notebook PC.Type: ApplicationFiled: January 9, 2009Publication date: July 23, 2009Applicant: Lenovo (Singapore) Pte.Inventors: Gang Ji, Tetsuya Ohtani, Takayuki Morino, Akinori Uchino

Publication number: 20090179806Abstract: The invention broadly contemplates an electronic apparatus that provides improved antenna characteristics, while maintaining a thin size and light weight. The electronic apparatus of the present invention includes a display casing having a nonconductive resin region and a conductive resin region in a bottom surface thereof; a display module accommodated in the display casing; an antenna disposed in the nonconductive resin region; and a system casing accommodating a wireless module connected to the antenna. By disposing the antenna in the nonconductive resin region formed in the bottom surface of the display casing, it is possible to secure high radio wave sensitivity while preventing an antenna mounting portion from being exposed to the outside of the display casing. The casing structure of the electronic apparatus does not become thick because of butt joining even when the joint portions are in a projection area of an LCD module.Type: ApplicationFiled: January 9, 2009Publication date: July 16, 2009Applicant: Lenovo (Singapore) Pte.

Publication number: 20050240358Abstract: The object of the present invention is to provide a genome information display system that allows the user to quickly conduct operations such as movement of display content on the screen presenting information of a gene or the like of a genome. A server 10, on receipt of a request for map screen from a terminal 60, transmits, to the terminal 60, a mass of map screen data necessary for preparing a map screen. Therefore, for example, when the user conducts operations such as movement, expansion/contraction of the display extension of an enlarged map on a map screen, the terminal 60, instead of making a renewed access to the server 10 for data communication, quickly prepares an enlarged map presenting the display extension according to the operation, based on the mass of map screen data stored in the memory means of the terminal 60, and displays the enlarged map at a high speed matched with the user's operation.Type: ApplicationFiled: April 21, 2005Publication date: October 27, 2005Applicant: Nittetsu Hitachi Systems Engineering, Inc.Inventors: Jun Sasaki, Tetsuya Ohtani, Kazuhiko Akizuki, Makoto Akeo

Publication number: 20030179543Abstract: A deformable shock absorbing device for a computer apparatus or a precision apparatus is provided. An embodiment of the shock absorbing portion includes an outer disk, an inner substrate with a valve, and an elastic member therebetween, creating a cavity whose inflow or outflow is allowed by the valve. When the computer apparatus is moved away from a resting surface, the elastic membrane facilitates the inflation of the shock absorbing device with air or fluid and the device projects outwardly from the bottom surface of the computer. If the computer comes into sudden contact with the surface, the force of impact is absorbed by the shock absorbing device which deflates gradually. Thus, internal structures of the computer apparatus can be prevented from being damaged.Type: ApplicationFiled: March 25, 2002Publication date: September 25, 2003Applicant: International Business Machines CorporationInventors: Sri M.
