Abstract: A multilayer inductor component has a multilayer part having a plurality of magnetic layers laminated therein and a conductor part arranged within the multilayer part. The magnetic layers are formed from a ferrite material and an additive. The ferrite material contains Fe2O3, NiO, CuO, and ZnO. Fe2O3 is 30 to 45 mol %. NiO is 45 to 58 mol %. CuO is 6 to 10 mol %. ZnO is 0 to 3 mol %. The additive contains CoO. The content of CoO is 0.1 to 2.5 mass % with respect to the ferrite material as a whole. The multilayer inductor component has an impedance peak of 500 ? or greater at an operating frequency of 1 GHz or higher.

Abstract: A communication circuit is provided with: a transmission and reception unit that transmits and receives communication signals through a telephone line; a connection unit that connects the transmission and reception unit to the telephone line; a detection unit that detects a line voltage value supplied from the telephone line; and a determination unit that determines a type of the telephone line, based on the line voltage value detected by the detection unit.

Abstract: A communication apparatus is provided with: plural transmission units that respectively transmit communication signals through a telephone line; a detection unit that detects a value of a line voltage supplied from the telephone line to each of the plural transmission units; and a controller that controls transmission from each of the plural transmission units, according to a relation between a predetermined reference voltage value and the value of the line voltage of each of the plural transmission units detected by the detection unit.

Abstract: The ferrite paste according to the present invention contains a ferrite powder and an organic vehicle, and the organic vehicle contains an organic solvent and a binder made of a polyvinyl acetal resin and ethyl cellulose. The binder content in the ferrite paste is at least 3.0 weight parts and no more than 5.0 weight parts per 100 weight parts of the ferrite powder, and the polyvinyl acetal resin content is at least 0.5 weight part and no more than 2.0 weight parts per 100 of the weight parts ferrite powder. The ethyl cellulose content is the remainder of subtracting the polyvinyl acetal resin content from the binder content.

Abstract: A data processing apparatus, capable of guaranteeing display operations when a destination terminal is a portable terminal apparatus, while the display operations are adapted to display capability of this portable terminal apparatus. The data processing apparatus includes a storage which stores first data therein, a convert section for converting the first data into second data, and a transmit section which transmits the second data to the destination. A judgment is made whether a destination is a portable terminal apparatus. When the destination is judged to be portable terminal apparatus, the convert section converts the first data into the second data based upon display capability of a data display apparatus of the data display apparatus.
