The hard film has a crystal structure comprised of mixed phases of CrN and TiN, and contains oxygen in a solid solution state in the CrN and TiN crystals. The hard film comprises chromium of 40 to 75 percent by weight, titanium of 10 to 40 percent by weight, oxygen of 0.5 to 15 percent by weight, and the remainder of nitrogen. The crystal particle size is within 1 &mgr;m. The Vickers hardness of the hard film is in a range of 1300 to 2300. The crystals of CrN and TiN have a preferred orientation of (200) surface or preferred orientation of (111) surface parallel to a surface being covered, and has a columnar structure developing in a columnar shape from the base material toward the film surface. Carbon in a solid solution state may be contained instead of oxygen, and both oxygen and carbon may be contained in a solid solution state. An under film of CrN may be formed between the nitrided layer and the hard film.

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.

摘要： A composite material comprising a bulky substrate of a Y-series 123 metal oxide crystal, and at least one layer provided on a surface of the substrate and formed of a crystal of a Y-series 123 metal oxide. The substrate may be produced by immersing a seed material in a liquid phase which comprises components constituting the metal oxide. The liquid phase contains a solid phase located at a position different from the position at which the seed material contacts the liquid phase. The solid phase provides the liquid phase with solutes which constitute the Y-series 123 metal oxide so that the solutes are transported to the position at which the seed material and the liquid phase contact, thereby permitting the Y-series 123 metal oxide to grow on the seed material as primary crystals and to obtain the bulky substrate. The layer of a Y-series 123 metal oxide may be formed on the substrate by a sputtering method, a vacuum deposition method, a laser abrasion method, a CVD method or a liquid phase epitaxy method.

摘要： A mobile communication system contains a mobile switching center connected to a plurality of base stations constituting a radio service zone and a plurality of mobile stations. The mobile switching center monitors the usage of a traffic channel for each radio service zone and has a usage threshold value for each radio service zone, and informs those to the mobile station via the base station. The busy mobile station compares the traffic channel usage information and the usage threshold value information and the radio zone communicated. When the traffic channel usage is greater than the usage threshold value, the mobile station selects a hand-over radio zone destination based on the received signal strength and quality, and the traffic channel usage information and the usage threshold value information of the adjacent zone, and then transmits a hand-over request designating the hand-over radio zone destination to the mobile switching center.
