Abstract: According to one embodiment, there is provided a multielement composite oxide powder that includes an oxide particle including a composite oxide, the composite oxide containing: constituent metal elements containing two or more hexavalent metal elements and two or more pentavalent metal elements at a content of 80 atm % or more in total; and oxygen. The oxide particle has a major axis and a minor axis intersecting the major axis, and has a polygonal tunnel structure including one or more polygonal tunnels of five or more vertices in a major axis direction along the major axis.

Abstract: An electronic apparatus includes an outer housing; a battery storage compartment provided in the outer housing and having a height and a width and depth larger than the height; a cover for opening and closing an opening of the battery storage compartment; and a battery ejecting spring disposed in a deep portion of the battery storage compartment and for urging a battery being stored in the battery storage compartment along a direction of ejection of the battery from the opening. The battery ejecting spring includes a pivot shaft, an anchor shaft, and an urging shaft. The pivot shaft extends along the width direction. The anchor shaft stops the rotation of the one end portion of the pivot shaft. The urging shaft includes a tip end engaging with an end face of the battery, thereby to perform a pivotal movement about the pivot shaft working as a fulcrum.

Abstract: In the present invention, a reading r and an expression e entered by an input unit are stored as history data. When a subsequent reading is entered thereafter, an input reading R1 is keystroke converted to input-reading keystrokes K1. The history data is also read, and the reading r is set as history-data reading keystrokes K2 and the expression e is set as an expression E1. A comparison is made between the data string of the input-reading keystrokes K1 and the data string of the history-data reading keystrokes K2. If they are forward-matched, the expression E1 is adopted and output as a candidate.

Abstract: A method for fabricating superconducting wires wherein a billet of copper containing filaments of niobium or vanadium is rolled to form a strip which is wrapped about a tin-alloy core to form a composite. The alloy is a tin-copper alloy for niobium filaments and a gallium-copper alloy for vanadium filaments. The composite is then drawn down to a desired wire size and heat treated. During the heat treatment process, the tin in the bronze reacts with the niobium to form the superconductor niobium tin. In the case where vanadium is used, the gallium in the gallium bronze reacts with the vanadium to form the superconductor vanadium gallium. This new process eliminates the costly annealing steps, external tin plating and drilling of bronze ingots required in a number of prior art processes.

Abstract: An improved multiwire conductor of the type which is mechanically stabilized by a tin based solder filler. A solder filled conductor is heated to a temperature above its melting point for a period long enough to allow a substantial amount of copper to be dissolved from the wires comprising the conductor. The copper forms the brittle intermetallic compound Cu.sub.5 Sn.sub.6 with tin in the solder. After cooling the conductor is flexed causing a random cracking of the solder, and thereby increasing the interwire resistance of the conductor. The subject invention is particularly adapted for use with braided, ribbon-type solder filled superconductors.

Abstract: A superconducting wire comprising a superconducting filament and a beryllium strengthened bronze matrix in which the addition of beryllium to the matrix permits a low volume matrix to exhibit reduced elastic deformation after heat treating which increases the compression of the superconducting filament on cooling and thereby improves the strain characteristics of the wire.

Abstract: There is provided a class of mechanically pre-stressed structures, suitably bi-layer strips comprising a layer of group 5 transition metals in intimate contact with a layer of an intermetallic compound of said transition metals with certain group 3A, 4A or 5A metals or metalloids suitably gallium, indium, silicon, germanium, tin, arsenic or antimony. The changes of Young's modulus of these bi-layered combinations at temperatures in the region of but somewhat above absolute zero provides a useful means of sensing temperature changes. Such bi-metallic strips may be used as control strips in thermostats, in direct dial reading instruments, or the like.
