  • Publication number: 20050170822
    Abstract: When a radio communication is made between a predetermined base station and a communication terminal, the communication terminal is allowed to make a communication if a predetermined registration processing is made. If the above registration processing is not executed, then predetermined functions other than a communication function of the communication terminal are limited. Moreover, when a predetermined operation mode is set by an operation means, at least a transmission processing at a radio communication means is stopped and an execution of predetermined functions other than the radio communication processing is not restricted. Thus, when a communication terminal apparatus incorporates therein other functions than an audio reproducing function, operation of such function can be limited properly.

  • Patent number: 5654674
    Abstract: A controllable crystal oscillator of a receiver having a mixer producing an IF signal is controlled by a feedback loop that includes a phase detector. The IF signal is delayed by an odd multiple of .pi./2 and fed to one input of an exclusive-OR circuit, with the other input receiving the IF signal directly. The phase detection signal from the exclusive-OR circuit can be counted and converted to an analog voltage when the oscillator is a voltage controlled oscillator or it can be counted and used as a digital control signal when the oscillator is a data controlled oscillator.
