摘要:
A high density magneto-optical recording medium utilizing a polycrystalline garnet two-layer film. The film thickness of an under layer of the garnet polycrystal on a glass substrate is made 100 nm or less, and a crystal grain diameter of a recording layer formed thereon is made 0.1 .mu.m or less. Furthermore, the under layer is demagnetized at room temperature. With this, a bit having a regular shape can be written, thus reducing medium noise by a large margin.
摘要:
A method of producing a polydiacetylene thin film comprises spreading on a water surface a diacetylene compound having one or more conjugated diacetylene groups, subjecting the diacetylene compound to incomplete polymerization by irradiation with ultraviolet rays to an extent incapable of causing complete polymerization, transferring the spread film to a substrate to form a monolayer or built-up film thereon, and irradiating the transferred film with ultraviolet rays or an electron beam to complete the polymerization thereof.
摘要:
A carbon oxide sensor having high sensitivity capable of reduction of influence of humidity is provided. A detection electrode and a counter electrode are provided on one side of an electrolyte, respectively. The detection electrode contains a metal oxide and a metal carbonate including plural components. The metal carbonate preferably contains a first component of alkali metal carbonate and a second component of at least one element selected from the group consisting of alkali earth metal carbonate, transition metal carbonate, zinc carbonate, cadmium carbonate, indium carbonate, lead carbonate and bismuth carbonate. Specifically, it is preferable to contain the first component including Li2CO3 and the second component including at least one element selected from the group consisting of BaCO3, CaCO3 and SrCO3.
