摘要： Improvement in a process for fabricating a superconducting junction by depositing successively a first oxide superconductor thin layer, a non-superconducting intermediate thin film layer and a second oxide superconductor thin film layer on a substrate in this order. In the ivention, the non-superconducting intermediate thin film layer is composed of MgO and the substrate is heated at a temperature between 200 and 400°C during the non-superconducting intermediate thin film layer is deposited.

摘要： 57 A magnetism sensor comprises a substrate, a SQUID including a washer of an oxide superconductor thin film formed on a principal surface of the substrate, a hole shaped a similar figure to the washer at the center of the washer, a slit formed between one side of the washer and the hole and a Josephson junction by which portions of the washer at the both sides of the slit are connected across the slit. The magnetism sensor further comprises a superconducting flux transformer of an oxide superconductor thin film including an input coil arranged on the SQUID but isolated from the SQUID and a pickup coil arranged on the principal surface of the substrate far from the SQUID, which are connected in parallel and a magnetism shield which excludes flux penetrating into the Josephson junction of the SQUID.

摘要： A silicon nitride ceramic sliding member which comprises Si 3 N 4 grains as a main component and is shaped or controlled in dimensions through hot plastic working wherein the Si 3 N 4 particles mainly comprises β-type columnar crystal grains. The ceramic sliding member is produced by the step (I) of preparing a preform made of silicon nitride ceramic sintered body comprising Si 3 N 4 grains as a main component wherein the average grain size (average grain size in minor axis in the case of β-type columnar crystal grains) of the Si 3 N 4 grains is at most 0.5 µm, and the hot plastic working step (II) of placing the preform in a mold and effecting hot plastic deformation of the preform for shaping or dimensional control thereof while simultaneously increasing the average aspect ratio of the β-type columnar crystal grains. The resultant sliding member has excellent sliding properties, a high mechanical strength and a high reliability at a low cost without resort to grinding or the like for shaping thereof.

摘要： A Josephson junction device comprising a single crystalline substrate including a principal surface having two horizontal planes and a smooth slope between the two horizontal planes, and an oxide superconductor thin film formed on the principal surface of the substrate. The oxide superconductor thin film includes a first and a second superconducting portions of a single crystalline oxide superconductor respectively positioned on the two horizontal planes of the substrate, a junction portion of a single crystalline oxide superconductor having a different crystal orientation from the two superconducting portions positioned on the slope of the substrate and two grain boundaries between each of the two superconducting portions and the junction portion. The grain boundaries constitutes one weak link of the Josephson junction.
