摘要： A process for producing a superconducting article having a layer of compound oxide of quasi-perovskite type oxide crystal structure by electrodeposition technique. The process is characterized by dispersing a material powder in a liquid containing a carrier, driving ionized material particles towards a substrate by applying a direct current between a substrate and a counter electrode, and then sintering a thin layer of powders deposited on the substrate to convert the deposited powders to a superconducting compound oxide.

摘要： A thin film of a preselected compound having a large area is continuously produced on a substrate by depositing elements constituting the preselected compound from a target member onto the surface of a substrate by sputtering, comprising the steps of:rotating a first target member having a flat surface disposed around an axis which crosses the surface and comprising elements of the preselected compound so that a first part of the surface of target member is positioned at a first sputtering position and another part of the first target member is positioned at a second sputtering position,at the first position, sputtering at least one second target comprising at least one element of the preselected compound which is easily sputtered from the first target member so as to supply the deficient element to the first target member, andat the second position, sputtering the elements from the first target member so as to deposit them on the surface of said substrate while continuously supplying the substrate so that a part of the substrate is positioned in the path of the sputtered elements,whereby the elementary composition of the first target member at the second position is adjusted to the preselected composition.

摘要： The invention relates to a diamond sintered compact wherein diamond crystal particles are uniformly oriented in a particular direction and the method for producing the same, and has for an object to provide a diamond sintered compact having a high thermal conductivity particularly suitable for heat sink for use in the field of electronics.According to the invention, graphite is used as carbonaceous raw material, diamond crystal particles having such elongated shape that the ratio of the length of the long axis to that of the short axis is more than 2 being synthesized in such state that the greater part of the crystal particles have their long axes uniformly oriented in a particular direction, the crystal particles being sintered in the direction of the long axes thereof so that transformation of the graphite into diamond and sintering thereof may be accomplished synchronously. The invention has for an object to obtain a diamond sintered compact suitable for the aforesaid use by degassing reaction system raw material plugged into an air permeable container by heating it in vacuum in order to intercept gaseous components causing a decrease of thermal conductivity at the time of synthesizing diamond from carbonaceous material and a catalytic metal and sintering thereof, subsequently the air permeable part of the said container being sealed by means of soldering material preliminarily placed in contact with the said container.

摘要： An improved sintered compact for use in a cutting tool is proposed which comprises 80 to 95 volume % of high pressure form boron nitride, a binder material which is a carbide, a nitride and/or a carbonitride of a IVb and Vb transition metal in the periodic table, and aluminum compounds. It may further include copper and/or iron group metal or metals. The sintered compact obtained has high hardness even though the sintering pressure and temperature are relatively low.
