    摘要: A gas nitrided layer is formed over the entire surface of a piston ring. A physical vapor deposition film of CrN is formed over the gas nitrided layer at the outer circumferential surface. The physical vapor deposition film has oxygen contained in a solid solution state in a crystal structure of CrN in a content of 0.5 to 20 percent by weight, pores dispersed at a rate of 1 to 15 percent within the film and a crystal structure of CrN with a preferred orientation (200) parallel to the surface being covered. The Vicker's hardness of the film is within a range of 1000 to 1800. The physical vapor deposition film of CrN can be formed beneath a wear resistant film covering the outer circumferential surface of the piston ring. The wear resistant film is for instance, a physical vapor deposition film of chromium nitride such as CrN or Cr.sub.2 N.

    摘要: There is provided a method for stably preparing rare earth (RE) 123 type oxide superconductors exhibiting outstanding superconductive properties in the atmosphere. In the method for preparing RE 123-type oxide superconductors by melting, cooling and solidifying a starting composition containing one or more than two kinds of RE such as Y, Sm, Nd, etc., and Ba, Cu and O as constituent elements to crystallize the RE 123-type oxide superconductors, the quantity of replacement between RE and Ba in "RE 123 crystals to be formed" is controlled by changing the initial constitution of the starting composition, for example, by changing the initial constitution to a more Ba-rich side than a composition on a 123-211 (or 422) tie line on a phase diagram to yield RE 123-type oxide superconductors in the atmosphere, which exhibits a critical temperature of 90 K or above and higher critical current density (Jc) in a magnetic field. A trace amount of Pt or CeO.sub.3 may be added to micronize the 211 (or 422) phase so as to further improve Jc.

    摘要: Passive radiators of the same effective vibration area and the same effective vibration mass disposed in mutual opposition, and driver units of the same effective vibration area and the same effective vibration mass disposed in mutual opposition, are mounted to a bandpass type enclosure. The vibration-reaction forces of the opposing passive radiators and opposing driver units on the enclosure are thereby mutually cancelled, and enclosure vibrations are thus greatly reduced. Powerful bass output can be achieved because the diameter of the passive radiators can be increased at will and the use of two passive radiators achieves an extremely large vibration area.

    摘要: A mobile communication system of a cellular type has in each cell a base station (12a-12c) for carrying out bidirectional communication between the base station and a mobile station (11). The base station announces a transmission power of the base station and up link reception power and up link signal quality as information to the mobile station. The mobile station judges whether nor not it is necessary to carry out a hand-over control in accordance with the information and a predetermined hand-over control information. The mobile station judges whether or not it is necessary to carry out said hand-over control in accordance with a down link received signal strength indicator, a down link received signal quality, and the predetermined hand-over control information. The mobile station may judge whether or not it is necessary for the base station to carry out a base transmission power control in accordance with the information and a base maximum transmission power. Furthermore the mobile station may judge whether or not it is necessary for the mobile station to carry out a mobile transmission power control in accordance with the information and a mobile maximum transmission power.

    摘要: In order to prepare a large yttrium or lanthanoid based oxide superconductor crystal of higher quality, a method and an apparatus which can stably control the shape of a pulled crystal and stably maintain growth of the crystal from a melt are provided. A crystal of an oxide having a structure of RBa.sub.2 Cu.sub.3 O.sub.7-X (R: yttrium or lanthanoid element, 0.ltoreq.X.ltoreq.1) is pulled from a raw material melt which is stored in a crucible by a rotary crystal pulling shaft. During such pulling, a position of the surface of the raw material melt is measured with time to obtain a lowering speed of the surface in a direction substantially parallel to the crystal pulling direction, for adjusting the lifting speed of the crystal pulling shaft by this lowering speed.
