Abstract: Provided is a communication network system capable of effectively utilizing a telephone number and a terminal identity assigned to a communication terminal. The communication terminal transmits to a network server a communication start request including a temporary telephone number and a mobile station identity which are previously permitted to use. The network server verifies the communication terminal based on the mobile station identity. At this point, the network server informs the communication terminal of the telephone number necessary for the communication terminal to continue communication. The communication terminal originates a call by using the telephone number and the mobile station identity.

Abstract: There is provided a mobile terminal device including a verification circuit verifying whether or not an attached external power supply meets a predefined condition, an internal power supply supplying power to the verification circuit, and a power management unit cutting power supply from the external power supply to a terminal body and supplying power from the internal power supply to the verification circuit during verification of the external power supply.

Abstract: A fluid feeding apparatus capable of excluding the outer environmental influences in feeding a fluid susceptible to contamination, decomposition or denaturation on contact with the outer environment. The includes comprises at least one liquid source container, a cleaning and/or diluting liquid container, a waste liquid collection container, an inert gas feed pipe A, an inert gas feed pipe B, an evacuation pipe connecting to a vacuum source, and a fluid feed pipe for introducing the fluid to a process. The source container has two pipes. The first pipe has valves arranged therein at positions nearer to and farther from the source container, respectively. The second pipe has two valves arranged therein at positions nearer to and farther from the container, respectively. The path between the valves 1 and 4 and the path between the valves 2 and 5 are connected via a connecting pipe C having a valve 3.

Abstract: A frequency adjusting circuit for use with a digital receiver is disclosed, the circuit comprising a means (mixers 3 and 4) for converting the frequency of a received digital signal into an intermediate frequency signal, a local oscillator (VCOs 7 and 8 and PLLs 9 and 10) for supplying a local oscillation signal to the frequency converting means, and a frequency adjusting means (20) for calculating a frequency deviation of the intermediate frequency signal (D1) for each sample, performing a predetermined calculation corresponding to the measured value, and controlling the oscillation frequency of the local oscillator corresponding to the obtained calculated value, wherein the frequency adjusting means compensates the calculated value corresponding to a receiving electric field intensity of the intermediate frequency signal.

Abstract: A receive condition in burst transmission varies in units of a burst or a plurality of symbol times. The present invention provides a soft decision signal outputting receiver which can simply produce correct reliability information even if the receive condition varies while employing a simple reliability information production method. A demodulator demodulates a burst signal to obtain a hard decision signal. A time-varying reliability information production circuit receives information of a demodulation process from the demodulator 11 and produces reliability information regarding the hard decision signal. The time-varying reliability information production circuit receives signal quality information which reflects a receive condition for each burst or each plurality of symbol times, and changes, based on the signal quality information, a production method for reliability information or elements such as threshold levels to be used in a production method for each burst or each plurality of symbol times.

Abstract: One frame of speech signal data and subframes of speech signal data divided from the frame of speech signal data are encoded by frame and subframe encoding processes while another frame is decoded by frame and subframe decoding processes. The frame and subframe encoding processes and the frame and subframe decoding processes are interleaved to reduce the DSP memory capacity needed for a speech codec.
