Title: Quasi-planar type josephson junction element
Inventor: KITA JUNICHI
IPC: H01L39/22
Filed: 1989-01-21
Abstract: PURPOSE:To obtain an excellent Josephson element by using oxide high temperature superconductor by a method wherein a superconducting thin film of almost uniform thickness is formed on the surface of a substrate, on which a step- difference is formed, so as to interpose the step-difference and to be positioned on both sides thereof, and both of the film surfaces are joined by a bridge of superconductor. CONSTITUTION:On the surface of an MgO substrate 1, a step-difference is formed. High temperature superconducting films 2, 3 made of YBCO are formed on the surface of the upper step side and the lower step side, respectively, so as to interpose the step part 1a. The surfaces of the thin films 2, 3 are joined by a bridge 4 made of YBCO. This manufacturing method is as follows. Resist is spread uniformly on a substrate; one side half thereof is eliminated by photolithography; Ar ion milling is performed by using the left resist as a mask, thereby manufacturing the substrate 1; a YBCO thin film is uniformly sputtered on the substrate; thereon negative resist is spread uniformly, and eliminated by exposure and development so as to leave the bridge 4 part; by using the remaining resist film as a mask, the YBCO thin film is etched, thereby obtaining the bridge 4 coming into contact with the thin films 2, 3.

Title: Direct beam stopper position adjuster for neutron diffraction apparatus
Inventor: MASUDA KENJI
IPC: G12B17/00
Filed: 1990-01-22
Abstract: PURPOSE:To shield a direct beam from a monochrometer surely by controlling the operation of a stopper driving means based on an output signal of a photo detecting means for receiving light from a light emitting means turning together with the monochrometer. CONSTITUTION:When a monochrometer 1 is step scanned in a direction A, light from an LED 24 moved in the same direction and a photodiode 25a among those 25a-25c is turned OFF to keep the photodiodes 25b and 25c ON. As a result, a motor 22 is driven to rotate positively with a control circuit 26 to move a truck 21 in a direction A' and when a direct beam stopper 17 moves again to a position at which a direct beam from the monochrometer 1 can be shielded, all of the photodiodes 25a-25c are turned ON again to stop the motor 22. Thus, even in the step scanning of the monochrometer 1, radiation of such neutron rays from the monochrometer 1 can be shielded surely.

Abstract: PURPOSE:To simplify a structure by calculating the moving position of a photographing optical system based on the viewing angle detected result and the object range-finded result of a finder optical system and moving a photographing optical system. CONSTITUTION:The focal distance of the photographing optical system is calculated in a main control circuit 30a based on a detecting viewing angle value. A distance for which first and second group lenses 1 and 2 are allowed to move with respect to an image forming plane is calculated based on the object distance detected value and this optical system moving quantity is stored in a memory.

Further, the shutter release button is completely stroke-pushed, the main control circuit 30a makes the motor 11 revolve through the motor driving circuit 30b so that the first and second lenses 1 and 2 are moved by only the calculated moving amount. Thus, the structure is simplified.
