Abstract: PURPOSE:To manufacture a Josephson junction element without providing an insulating layer between superconductors by a method wherein two superconductive crystals are made to grow, and a grain boundary formed by bringing the superconductive crystals into contact with each other is used as a Josephson junction. CONSTITUTION:A pattern of pairs of nucleus forming planes 1 formed of Al2O3, TiO2, or the like is formed on a substrate 2. And, a non-nucleus forming plane 5 formed of Si, SiO2, or the like can be provided through a specified treating process performed onto the substrate, and the substrate 2 itself can be made a non-nucleus forming plane. Then, a superconductive crystal forming material is deposited through sputtering on the substrate 2 where the nucleus forming planes 1 have been formed to enable superconductive crystals 4 to grow. At this point, as the nucleus formation density of the nucleus forming plane 1 is larger than that of the non-nucleus forming plane 5, a stable single nucleus is selectively formed only on the plane 1, and a superconductive crystal grows making the single nucleus serve as a seed. With the advance of growth of a single crystal, the single crystal keeps growing in parallel with the substrate plane to the plane 5 making the single nucleus a starting point, and the crystals come in contact with each other at required position to form a grain boundary.

Filed: 1982-12-01
Abstract: PURPOSE:To form a variable power optical system having a compact and simple lens barrel structure by providing at least two lens groups, and varying the refractive powers of these two lens groups. CONSTITUTION:A variable power optical system is constituted of four lens groups, and an afocal system is constituted from the first lens group to the third lens group in order from an object side. The reflective powers of respective lens groups in a reference state are denoted as psi1, psi2, psi3 and psi4, respectively from the object side, and principal point intervals between each lens group are denoted as e1, e2 and e3, respectively. In this state, for instance, when the refractive power of the second lens group is varied to psis from psi2, if the refractive power psit of the third lens group is derived so that a focus surface of the variable power optical system becomes constant, psit=-A/(H-e2.A). Wherein H=1-e1.psi1 and A=psi1+H.psis, and accordingly, it is satisfactory that the refractive power psit of the third lens group is varied as said equation. According to this invention, the variable power optical system can be realized without moving the lens group on the optical axis.
