摘要:
A method of manufacturing a paint composite for magnetic films wherein a mixture consisting of a magnetic powder, a polymer such as polyvinylbutyral, and a solvent is ground under a shear stress of 10-400 kg/cm.sup.2, and the ground mixture has a solvent, an epoxy resin and a phenol resin added thereto and is further ground. When a magnetic disk is produced using a paint which has been obtained by executing the first grinding under a shear stress of 10-400 kg/cm.sup.2 with a kneader or the like, it is endowed with excellent electric characteristics and surface flatness.

摘要:
A process for the preparation of a magnetic recording medium comprising;applying a magnetic coating material composed of dispersing a ferromagnetic fine powder in a high molecular binder onto the surfaces of a nonmagnetic support member to form a coating thereon;arraying one or more sets of magnet pairs on the sides of front and back surfaces of said support member, each of said magnet pairs being deviated by a predetermined distance in the moving direction of said support member such that said magnet pairs will not face to each other; andapplying a magnetic field in such a manner that the magnetic field applied to said coating by the magnet pairs arrayed on the side of the front surface of said support member is greater than the magnetic field applied to said coating by the magnet pairs arrayed on the side of the back surface of said support member, thereby satisfying the requirements ofDo.ltoreq.a,b wherein Do represents a distance between the surface of said support member and said magnet pairs, a an average distance between the magnets constituting said magnet pairs arrayed on the side of the front surface of said support member, and b an average distance between the magnets constituting said magnet pairs arrayed on the side of the back surface of said support member.

Disclosed is a recording member which comprises a substrate and a recording layer containing at least selenium and at least one element selected from the group consisting of tellurium and bismuth, wherein the selenium content is higher in the vicinity of the surface of the recording layer and/or in the vicinity of the interface between the recording layer and the substrate than the average selenium content in other portions. By virtue of the presence of this high selenium content portion, the oxidation resistance and water resistance are improved, and a recording member having stable characteristics can be obtained.
摘要:
A buffer circuit ID provided for connecting an atom level device (for example, an Atom Relay Transistor circuit), formed by arranging atoms in a predetermined pattern, to a device such as a semiconductor device and a quantum device. The buffer circuit can be formed as a voltage or current amplification circuit. The voltage amplification circuit may be a single electron transistor circuit, and the current amplification circuit may be an avalanche amplification device circuit. The Atom Relay Transistor circuit and the device such as a semiconductor device and a quantum device are formed substantially on the same flat insulating member, and connected by a fine connection structure made of a conductive body such as metal.

摘要:
A recording medium in which a substrate, an inorganic material layer adapted to absorb light and generate heat, a first organic material layer made of an organic matter containing metal, and a second organic material layer adapted to be deformed or removed by heat are successively stacked. A metal salt of an organic acid, or organic metal compound etc. are employed for the first organic material layer. Owing to the presence of this layer, the recording medium exhibits a stability against changes in the ambient temperature.
