Abstract: A microphone rubber apparatus mounted on an SMD microphone prepared on a printed circuit board to protect the SMD microphone from an external physical impact and the like in a portable communication device such as a portable terminal and a Personal Digital Assistant (PDA). The microphone rubber apparatus includes a microphone holder portion formed to engage with and wrap up a microphone, a connection portion protruding to one side of the microphone holder portion and delivering a transmission sound to the microphone through an inside thereof, and at least one shock absorbing portion deformably formed around the connection portion to ease an impact caused by an external force. Thus, the shock absorbing portion having a wrinkled shape can be deformed no matter in which direction an impact is applied to the portable communication device, thereby easing the impact and preventing the microphone rubber from being detached from the microphone due to the external impact or during a distribution test.

Abstract: A method for fabricating multi-component nanowires is disclosed, which can make multi-component nanowires used to realize a nanowire-based memory device by an electroplating process using a multi-component solution. The method for fabricating multi-component nanowires in accordance with the present invention includes the steps of: (a) preparing an anodized aluminum oxide nanotemplate having a plurality of pores; (b) forming an electrode layer on one surface of the anodized aluminum oxide nanotemplate; (c) injecting the anodized aluminum oxide nanotemplate in a predetermined multi-component solution and then growing multi-component nanowires through the pores of the anodized aluminum oxide nanotemplate by an electroplating process in which the anodized aluminum oxide nanotemplate is used as a cathode; and (d) removing the anodized aluminum oxide nanotemplate.

Abstract: Disclosed are an Fe—Au barcode type nanowire and a method of manufacturing the same. The nanowire has a magnetic-optical multifunction and is suitable for adjusting magnetic intensity thereof. The Fe—Au nanowire has a multilayered structure, in which an iron layer and a gold layer are alternately and repeatedly formed, and is formed in a single plating bath through a pulse electro-deposition.

Abstract: Disclosed is a character service method using duplex communications through wire/wireless networks. According to the method, predetermined points are given to a user according to the user's purchase of an item or activity relating to the character. When the points have been accumulated up to a predetermined level at which the user is regarded as having an affinity for the character, a character call including the character's voice or dynamic image proper for the user's situation is transmitted to the user, so as to enhance the user's affinity for the character.
