摘要:
An information recording material comprising a substrate and a metallic recording layer, the metallic recording layer comprising a Bi film containing at least one rare earth element. The information recording material exhibits a remarkably increased sensitivity while maintaining a high S/N ratio. Where the information recording material further comprises at least one stabilizing layer of a metal oxide and/or at least one mixture layer of a metallic compound and a metal, further improvements can be attained with respect to S/N ratio, storage stability and archivability.
摘要:
An information recording material comprising a substrate, a metallic recording layer composed mainly of Bi and a Cr layer interposed therebetween has been found to be extremely excellent in C/N ratio as well as in storage stability and archivability. The information recording material of this type can be advantageously employed for video image signal memory, still video recording, and the like.
摘要:
An information recording medium comprising a substrate and superimposed thereon a recording layer composed of Sb, Te and Ge has been found to be advantageously employed, because of its high thermal stability as well as high sensitivity and high S/N ratio, in a system of recording information by exposing an energy beam to a recording medium to cause the exposed areas to be different in optical extinction coefficient from the non-exposed areas.

While machining a workpiece with a tool of a machine tool according to a numerically controlled machining program, when the tool breaks, the workpiece is removed from the machine tool and a new workpiece is substituted. A new program for the new workpiece is selected and a new tool for machining the new workpiece is selected and substituted for the broken tool. Now the new workpiece is machined in accordance with a new program. The workpieces removed from the machine tool are collected, fragments of the broken tools are removed therefrom, and then machined again. A tool magazine containing a plurality of tools is provided. Broken tools are removed from the machine tool and returned to the tool magazine. When all tools in the tool magazine are judged to be broken, new tools of the same type are supplemented. When the tools are worn out similar steps are executed.

摘要:
A thermoelectric material having a high Seeback coefficient and a large power factor and excellent in shock resistance, thermal strain resistance, and formability, and a thermoelectric element are disclosed. The thermoelectric material and thermoelectric element is composed of a multilayered body made up of a laminar body of a semimetal, a metal, or a synthetic resin and a laminar body of a semimetal. The average thickness of the laminar bodies ranges from 0.3 nm to 1000 nm. Embodiments of the combination of the laminar bodies are Bi—Al, Bi-polyamide series resin, and Ag—Fe. Such a multilayered body is manufactured by forming an initial multilayered body composed of all the types of laminar bodies constituting the multilayered body and rolling or uniaxially pressing a stack of such initial multilayered bodies.

Thermoelectric materials with a high Seebeck coefficient and a large power factor are provided. The materials are impact resistant and resistant to heat-distortion. Such materials include a rare earth element, Bi, and Te and have a rhombohedral crystal structure. In some examples, the rare earth element is selected from the group consisting of Ce, Sm and Yb. Such materials can be formed as films with a thickness of from 0.01 to 500 μm on a resin substrate. Production methods may include laminating different types of layers of thickness of 20 nm or less and heat-treating the resultant composition-modulated composite. The material may be separated from a substrate for sintering.
