    摘要: A surface wave filter element includes a portion on which elastic surface waves propagate. This portion includes a piezoelectric material, an amorphous boron layer or plate and IDT electrodes for inputting and outputting signals. The piezoelectric material is a film made of ZnO, LiNbO.sub.3 or LiTaO.sub.3 formed by sputtering, ion beam deposition or chemical vapor deposition. The amorphous boron layer or boron plate may be formed on a substrate made of an inorganic material. The boron material is formed using electron beam deposition, ion beam deposition or chemical vapor deposition.

    摘要: A magnetic recording medium, comprising; a 2-layer film formed on a glass disk substrate as an under layer composed of an amorphous oxide or NaCl oxides like a NiO or CoO and the like, or any soft magnetic oxide of Mn-Zn ferrite, Ni-Zn ferrite and the like, or a combination of those 2 materials; a magnetic recording medium formed thereon composed of a Co ferrite perpendicular magnetic film of a columnar structure; and a structure formed thereon with a lubricant layer medium. This magnetic recording medium is used for a magnetic rigid disk apparatus. The substrate is made by press-molding the glass plate at a high temperature. The under layer film and Co ferrite film are composed of vapors of organic material compounds and oxygen as their raw materials, and made by a plasma assisted CVD method.

    摘要: The first object of the present invention is to provide a PDP with improved panel brightness which is achieved by improving the efficiency in conversion from discharge energy to visible rays. The second object of the present invention is to provide a PDP with improved panel life which is achieved by improving the protecting layer protecting the dielectrics glass layer. To achieve the first object, the present invention sets the amount of xenon in the discharge gas to the range of 10% by volume to less than 100% by volume, and sets the charging pressure for the discharge gas to the range of 500 to 760 Torr which is higher than conventional charging pressures. With such construction, the panel brightness increases. Also, to achieve the second object, the present invention has, on the surface of the dielectric glass layer, a protecting layer consisting of an alkaline earth oxide with (100)-face or (110)-face orientation. The protecting layer, which may be formed by using thermal Chemical Vapor Deposition (CVD) method, plasma enhanced CVD method, or a vapor deposition method with irradiation of ion or electron beam, will have a high sputtering resistance and effectively protect the dielectrics glass layer. Such a protecting layer contributes to the improvement of the panel life.

    摘要: Disclosed herein is a perpendicular magnetic film of spinel type iron oxide formed on a surface of a base substrate in the form of columnar grains which are densely arranged perpendicularly to the surface of the base substrate. A vapor of an organic iron compound or a mixed vapor consisting of the organic iron compound vapor and a vapor of an organic metal compound different from the organic iron compound is added with oxygen to obtain a mixed gas. The mixed gas is subjected to chemical vapor deposition on the substrate at low temperature, at reduced pressure in plasma, thereby to obtain the perpendicular magnetic film.
