Publication number: 20150005043Abstract: A housing 10 provided in a portable terminal device according to the present invention includes a plurality of stacked carbon fiber layers 21 to 24. Further, the direction of carbon fibers of the carbon fiber layer 21 disposed on the outermost side of the housing 10 among the plurality of carbon fiber layers 21 to 24 is conformed to the longitudinal direction d1 of the housing. The carbon composite material has such properties that the thermal conductivity is high and the strength is large along the direction of the carbon fibers. Therefore, with this configuration, heat can be preferentially diffused in the longitudinal direction d1 of the housing 10 and the strength in the longitudinal direction of the housing 10 can be improved.Type: ApplicationFiled: October 2, 2012Publication date: January 1, 2015Inventor: Mitsutaka Shiraishi

Patent number: 7483725Abstract: In recent years, a design where a microphone is not located in a position appropriately facing the oral cavity of an operator has been widely adopted from a viewpoint of convenience of miniaturization and mounting of a mobile telephone. When telephonic communication is made with such a mobile telephone, if a voice of the other party for telephonic communication is hard to hear, the operator necessarily tightly presses his/her face against a front surface of a chassis. Thus, the sensitivity and sound collecting property of the microphone are reduced. In the present invention, when a sound hole as a voice transmission path is formed in the vicinity of a manipulation section, slits are formed in the peripheries of the manipulation section and the sound hole.Type: GrantFiled: October 27, 2004Date of Patent: January 27, 2009Assignee: NEC CorporationInventor: Mitsutaka Shiraishi
