摘要:
In an audio sound recording/reproducing apparatus, instruction information related to a document is recorded in a recording region of a semiconductor memory together with the document. In the semiconductor memory, flags related to a document portion and an instruction portion, and the addresses of the document and the instruction portions are provided. At the time of reproduction, the instruction portion is reproduced prior to reproduction of the document portion. When the content of the semiconductor memory is stored in a built-in memory in the apparatus, the instruction portion is stored before the document portion is stored. Since the instruction portion is reproduced prior to the document portion at the time of reproduction, the user does not have to retrieve the instruction portion.
摘要:
An optical recording medium of a single plate type comprises a substrate, a recording layer overlying the substrate, a reflective layer overlying the recording layer, and a protective layer overlying the reflective layer, the recording layer being produced by coating a nonpolar solvent-soluble substituted phthalocyanine dye in a nonpolar solvent and the nonpolar solvent content of in the recording layer being 5% by weight or less.
摘要:
An insulative coat film comprising one or two or more kinds of oxides having a dielectric constant (k) of 2.5 or smaller and expressed by a general formula of ((CH3)nSiO2-n/2)x(SiO2)1-x (where n=1 to 3, x≦1) is used to form an interlayer insulation film. The insulative coat film applied by spin-coating is flat without reflecting underlying unevenness, and the heat-treated film has surface roughness of 1 nm or less in Ra and 20 nm or less in a P-V value. The interlayer insulation film containing the insulative coat film can have a wiring structure and an electrode formed only by etching without need of a CMP process.
