摘要： Stabilized carrier recovery is achieved even at the time of a low C/N ratio by measuring the phase of a signal and controlling VCO or NCO (Numerical Controlled Oscillator) using only a period having few constellation points. At this time, false lock phenomenon is avoided as follows. That is, relatively short SYNC modulated by an already-known pattern is entered into a modulation wave, VCO or NCO oscillation frequency is swept in a wide range and sweep is stopped at a frequency in which the SYNC can be received, thereby carrying out coarse control AFC. Further, a period having long to some extent, having few constellation points is provided in the modulation wave and then, a difference between the frequency of a received modulated signal and a local oscillation signal of VCO or NCO is obtained in this period. This frequency difference is analyzed according to the phase differential function method, self-correlation function method or count method, and the VCO or NCO is controlled based on this result of analysis.

摘要： In a superconductor mixer, a non-linear element is provided on a substrate. The non-linear element comprises at least one Josephson junction connected in series. An antenna pattern of superconductor, an intermediate frequency output pattern of superconductor, and a bias current pattern of superconductor are connected to the non-linear element. A signal high frequency wave (RF) and a local reference frequency wave (LO) are received by the antenna pattern and then absorbed in the non-linear element to obtain an intermediate frequency (IF) signal. Then, with applying a current to the series connected Josephson junction in the non-linear element from the bias current pattern, the intermediate frequency (IF) signal as a frequency signal of a difference between the signal high frequency wave (RF) and the local reference frequency wave (LO) is output to the intermediate frequency output pattern. At this time, by varying the current supplied from the bias current pattern, a phase of the output intermediate frequency (IF) signal is varied.

摘要： A method of selecting a radio base station (BS) in a mobile communication system adapting a plurality of voice coding methods is provided. This method reduces a probability of failure in allocating speech channel at the BS after having been selected. Each BS broadcasts the usage rate of the speech channel for each method through a control channel, in connection with speech channel groups which can be allocated. The MS selects a BS as a candidate to be connected, which is optimum in view of receiving state of the control channel and the usage rate of the speech channel, at the time of waiting state after having power put on or during hand-over operation.

摘要： In order to stably retain an oxide-based melt consisting essentially of yttrium or a lanthanoid element, barium, copper and oxygen at a prescribed temperature with no impurity contamination thereby preparing a large oxide crystal of high quality from the melt, an oxide melt consisting essentially of yttrium or a lanthanoid element, barium, copper and oxygen is stored in a first crucible, which in turn is held in a second crucible. The first crucible is made of a material which is an oxide of at least one element forming the melt having a melting point higher by at least 10.degree. C. than a melt retention temperature and causing no structural phase transition up to a temperature higher by 10.degree. C. than the aforementioned prescribed temperature, with solubility of not more than 5 atomic percent with respect to the melt in a temperature range from the room temperature to a temperature higher by 10.degree. C. than the melt retention temperature. The second crucible is made of a material substantially causing neither melting nor chemical reaction with respect to the oxide-based melt, which can retain the melt more stably than the first material. Even if the melt overflows the first crucible, this overflow is suppressed by the second crucible. It is possible to prepare a crystal of an oxide superconductor such as YBa.sub.2 Cu.sub.3 O.sub.7-x (0.ltoreq.X.ltoreq.1) by the pulling method from the melt which is stored in the first crucible.
