Abstract: PURPOSE:To suppress the reduction in superconducting characteristic in a magnetic filed by putting a Tl(Pb)-Ba(Sr)-Ca-Cu-O oxide powder in a tube made of silver or gold, by rolling it, and by applying a zonal melting process to it. CONSTITUTION:A Tl(Pb)-Ba(Sr)-Ca-Cu-O oxide powder is mixed in a preset compositional ratio, is formed, and a molding body is tentatively baked in oxygen, and its powder is put into a tube made of silver or of hold that does not react with the molding body. The tube containing the oxide material is processed into a wire rod of circular cross section through the combination of die rolling and rolling, and a zonal melting process is applied thereto. In the zonal melting process, the wire rod 1 obtained by the aforementioned processes is supported in a quartz tube 2 by a hanging rod 3, and is turned and gradually lowered at the same time, heated and melted in an oxygen air current with an infrared lamp 5 as a heating source. A reflecting mirror 6 in the form of dual ellipse is put on a heating zone, so as to have the heat converged on the wire rod 1, and the zonal melting process is carried out from one end of the wire rod to the other end. Since the wire rod obtained by this method has an improved orientational feature, Jc can be increased.

Title: High speed welding method
Inventor: TERUNUMA TOSHIKATSU
IPC: B23K9/00
Filed: 1986-02-10
Abstract: PURPOSE:To eliminate the need to execute an adjustment and an attachment of a tab plate, and to easily execute a high speed welding, by executing the welding for a prescribed time by the welding start voltage, current and speed whose values are smaller than stationary welding voltage, current and speed at the time of start of welding. CONSTITUTION:An arc is started by impressing a hot voltage whose voltage is higher than a stationary welding voltage. As soon as the arc is started, the voltage is controlled to a welding start voltage whose voltage is lower than the stationary welding voltage, and also a welding start current is controlled to a smaller value than that of a stationary welding current. Also, a moving speed of a truck is increased slowly, and controlled so that a small welding start speed is obtained. After welding has been executed for a prescribed time by said welding start voltage and welding start current, and thereafter, the voltage and the current are raised gradually, and set to a stationary welding voltage and a stationary welding current. As for a welding speed, the rise start time is delayed from the voltage and the current, and the rise time for obtaining the stationary welding speed is shortened. In the welding terminal part, said voltage and current are dropped to a little smaller values than those of the stationary welding voltage and current.

Title: Ion plating apparatus
Inventor: KAIZUKA TAKANORI
IPC: C23C14/32
Filed: 1982-02-22
Abstract: PURPOSE:To provide an ion plating apparatus constituted so as to be capable of forming a thin film with a uniform thickness at high yield without rotating a substrate, by generating a rotary magnetic field on the substrate to which ion particles are deposited by using a permanent magnet. CONSTITUTION:Particles to be deposited are ionized while moved toward substrate 3 from an evaporation source 2 in a bell jar 1 and deposited on the substrate 3. To the external part of the bell jar 1, a permanent magnet 4 and a permanent magnet 6 rotated at a position offset from the center of the substrate 3 in opposed relation to said magnet 4 are provided so as to oppose the different poles thereof and a rotary magnetic field is generated to rotate ion beams. In this case, because magnetic flux density in the vicinity of the magnetic pole of the magnet 6 becomes high and ion streams are collected by and focussed to said magnet 6, the density of ion reaching the substrate 3 becomes high. By this mechanism, a film thickness is made uniform and the enhancement of film forming speed is attained.

Abstract: PURPOSE:To reduce the number of arithmetic steps of a high order polynomial by applying multiplication or division or addition at the same time, providing an auxiliary register to a high speed multiplication and division circuit and providing a selection circuit for an input from a data bus and an output of multiplication/division circuit to an input section of the adder circuit. CONSTITUTION:Registers (R) 1, 5, 6 store respectively input data. A conversion ROM 2 outputs a reciprocal of data of the R 1, an MPX 4 selects any of outputs of the R 1 and R 5 and of the ROM 2. A multiplication circuit 7 multiplies an output of the MPX 4 with an output of an R6 on a Galois field GF (2<m>). An MPX 8 selects either an input data or an output of the said operating device and a gate circuit 10 outputs the MPX 8 as it is or outputs 0. Further, an adder circuit 11 adds an output of the multiplication circuit 7 and an output of the circuit 10 on a Galois field GF (2<m>) and the result is used as the output of the said operating device. Thus, data S is stored in the R5, and gate control is applied at the same time to attain the operation obtaining S<k+1> from S<k> without inputting the data S. Further, the number of arithmetic steps is reduced by latching directly the result of operation to the R 9.

Protective covers 5 and 15 respectively prevent the film information group I and exposure information group II from being inadvertently set by accidental contact. The frame number of a film, photographic sensitivity, etc., are set in the information group I; they are displayed on the display device III when the cover 5 is shut. In the information group II, when the input key 12 is pressed after the cover 15 is opened, the display of the display device III sequentially varies. When a desired display is shown, pressing the key is stopped. The keys 13 and 14 are used for setting a desired value. Information with a high frequency of alteration requires operation by one operation member and information with a low frequency requires operation by two operation members. Therefore, this prevents inadvertent input and provides security.
