Abstract: The present invention addresses the problem of providing, by a method in which an expensive manufacturing apparatus is not required, an implant material having osteoconductivity superior to that of an implant material containing an aromatic polyether ketone. The present invention pertains to: said method including immersing an aromatic polyether ketone in a strong base solution in the absence of a calcium ion, and immersing an aromatic polyether ketone, which is obtained by the immersing, in a liquid containing a phosphorus-containing compound; and an implant material obtained by said method.

Abstract: A high-frequency module includes a diplexer, first and second high-frequency switches, a SAW duplexer, first and second LC filters functioning as first and second filters, and an SAW filter functioning as a third filter, the module defines a unit that integrates front-end sections of first to third communication systems, a digital cellular system (1.8 GHz band), a personal communication service (1.9 GHz band) and a global system for mobile communications (900 MHz band).

Abstract: A mobile communication device, preferably in the form of a dual-band cellular phone, includes two communications systems supporting different frequency bands, such as DCS in the 1.8 GHz band and GSM in the 900 MHz band. The mobile communication device includes an antenna, a high-frequency composite unit, DCS and GSM transmitters, and DCS and GSM receivers. The high-frequency composite unit contains a diplexer, DCS and GSM high-frequency switches, DCS and GSM high-frequency filters or notch filters, and a directional coupler.

Abstract: A low-pass filter is defined by a laminate containing an inductor electrode, a plurality of capacitor electrodes, and at least two ground electrodes. The laminate is defined by a plurality of laminated dielectric layers. The low-pass filter includes a grounded capacitor defined by a capacitor electrode and the at least two ground electrodes, the capacitor being located between the ground electrodes, and an ungrounded capacitor including a capacitor electrode which is not located between the ground electrodes.
