Abstract: PURPOSE:To obtain the subject superconductive oxide film having few defects and capable of film formation at low temperatures by reacting an evaporation beam composed of superconductive oxideconstituting elements with oxygen in plasmatic condition, depositing it on a substrate and promoting bonding between the constituting elements and oxygen during film formation. CONSTITUTION:Y and B are respectively set to EB heat-evaporation sources 101 and 102 and Cu metal is set to a resistance heating-evaporation source 103. A vacuum chamber 117 is then evacuated to 3X10<-6>Torr and O2 gas is subsequently introduced 113 so as to control the degree of vacuum in a glass tube 111 to 1-8X10<-2>Torr. RF power is then applied to an RF coil 112 and O2-glow discharge plasma in the tube 111 is pinched. On the other hand, an MgO single crystal substrate 114 ia heated at 550-650 deg.C and electric power is applied to the evaporation sources 101-103 respectively, thus forming the objective superconductive oxide film having 2000-3000Angstrom  thickness, e.g. Y1Ba2Cu3 O7-x superconductive film (X-ray diffraction pattern of the above mentioned film is shown by figure) on the substrate 114, e.g. at 0.5-1.0Angstrom /sec film-forming rate.

Title: Suspension polymerization of vinyl chloride monomer
Inventor: AMANO TADASHI
IPC: C08F14/00
Filed: 1985-12-16
Abstract: PURPOSE:To obtain a vinyl chloride polymer having a high bulk density and a high rate of absorbing plasticizer, by suspension-polymerizing a vinyl chloride monomer so that the ratio of the degree of polymerization of the final product to that of the polymer in the middle course of polymerization may fall within a specified range. CONSTITUTION:In performing a polymerization reaction by feeding a polymerization vessel with an aqueous medium, a dispersant, a polymerization initiator and a vinyl chloride monomer, said reaction is controlled so that the difference in the average degree of polymerization between the obtained vinyl chloride polymer as the final product and the vinyl chloride polymer at a polymer conversion >=10% may fall within + or -10% of the average degree of polymerization of the final product. Indispensable requirements for practicing this process are to raise the polymerization temperature stepwise or continuously within a range of 10-80 deg.C and to control it so that the average degree of polymerization of the polymer at a polymer conversion >=10% may fall within 90-110% of the average degree of polymerization of the final product. Any change in the average degree of polymerization of the polymer at a polymer conversion <=10% exerts no particular influence upon the quality of the final product.

Title: Semiconductor integrated circuit
Inventor: SEKI TERUCHIKA
IPC: H03K3/037
Filed: 1988-11-09
Abstract: PURPOSE:To check that set/reset active is generated in a flip flop with set/reset by detecting a spike occurring at an external output terminal. CONSTITUTION:A set/reset active check circuit 2 reads the change of a signal to be inputted to the input of the flip flop(FF) 1 with set/reset and the signal to be inputted to its R-input by using FFs 19, 21, 20, 22. Then, when both the set and the reset in the FF 1 change in the same pattern, it makes NORs 24, 25 generate the spike to inform that the set/reset active is generated, and makes them output it to a buffer 27. Besides, a signal to inform the inhibited state of the simultaneous active of S and R of the FF1 is outputted by an AND 23, and is transmitted to EN of the buffer 27, and if the change of S and R of the FF 1 in the same pattern is not the inhibited state, it outputs a spike signal to mean that the S-R active is generated to an output terminal 3. On the other hand, if the change is the inhibited state, it outputs the signal Z (high impedance) to mean that the inhibited state is generated to the output terminal 3 by the operation of EN of the buffer 27. Thus, a fact that the set/reset active is generated in the FF 1 can be checked.

Title: Magnetic field direction sensor
Inventor: NAKAYAMA YASUHIKO
IPC: G01R33/02
Filed: 1987-11-10
Abstract: PURPOSE:To obtain the title magnetic field direction sensor of simple constitution which is improved in resolution in a magnetic field direction and detects the magnetic field direction with high sensitivity regardless of whether the magnetic field is an electrostatic magnetic field or varying magnetic field by arranging a magnetic sensor inside an extensible pipe made of a superconductor. CONSTITUTION:The magnetic sensor 4 is installed at the center part of the space 5 connecting opening parts 2 and 3 of the pipe 1 made of the superconductor. Here, a magnetic field 6 arriving from beside the pipe 1 is repelled outward from the pipe by Meissner effect. A magnetic field 7 entering the pipe 1 from one opening part 2, on the other hand, passes through the pipe 1 and the magnetic sensor detects that. Thus, the magnetic sensor 4 detects only the magnetic field passing through the space 5 in the pipe 1, so the spatial resolution is improved. Then the measurement direction is changed in order to accurately detect the magnetic field direction.
