摘要:
The present invention provides a deposited multi-layer device with high reliability, which allows to reduce a weight, a production cost, and to avoid a peeling of a film, a crack and a curl of a substrate. The present invention relates to a deposited multi-layer device formed on a plastic substrate which is coated with a film of a buffer layer being made of an inorganic material on at least one surface of said substrate, wherein a total stress of the buffer layer is not greater than +700 Pa.m and not smaller than -700 Pa.m.
摘要:
An intensity of light reflected on a phase-changing type of information recording medium is changed since unrecorded and recorded portions of the recording medium have different phase states so that reflectivities of the unrecorded and recorded portions are different from each other. Such an intensity change takes place in a very short time immediately after a recording pulse is irradiated onto the phase-changing type of information recording medium. In a recording and simultaneous verifying method of the phase-changing type of information recording medium, the change in intensity of light reflected on the phase-changing type of information recording medium is detected by using this light reflected simultaneously with a recording pulse irradiated onto the phase-changing type of information recording medium. It is confirmed if the information is correctly recorded by detecting the reflected light. Thus, this information can be recorded to the information recording medium and can be simultaneously verified.
摘要:
A deposited multi-layer device of an electronic element and a plastic substrate on which an inorganic substance thin film layer is simultaneously formed on both surfaces of the substrate wherein each of the electronic element, plastic substrate and inorganic thin film have internal and thermal stress not equal to zero. The device is free from peeling, deformation or curl of the substrate and degradation due to impurities such as acid, alkali and water.
