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:
A thick film varistor comprising a thick film consisting essentially of 20 to 85 weight percent of tin oxide having an additive such as antimony oxide, and 15 to 80 weight percent of a glass frit such as a zinc barium borate glass. This thick film varistor is advantageous for its high n value (i.e. high voltage dependence of resistivity) and its low varistor voltage (i.e. voltage above which its resistivity abruptly decreases).

In the semiconductor memory device having a resistance memory element, a first transistor having a drain terminal connected to one end of the resistance memory element and a source terminal connected to a ground voltage, and a second transistor having source terminal connected to the resistance memory element, when a write voltage is applied to the resistance memory element via the second transistor to switch the resistance memory element from a low resistance state to a high resistance state, a voltage is controlled to be a value which is not less than a reset voltage and less than a set voltage by applying to a gate terminal of the second transistor a voltage which is not less than a total of the reset voltage and a threshold voltage of the second transistor and is less than a total of the set voltage and the threshold voltage.
摘要:
A plasma display device has a first plate and a second plate which face each other with a discharge space therebetween, and a sealing member which is provided between the first and second plates to seal the discharge space at edges of the first and second plates. A plurality of electrodes are formed on the inner major surface of the first or second plate. An electrode diffusion preventive layer is formed in each area where the plurality of electrodes cross over the sealing member, so as to avoid direct contact between the plurality of electrodes and the sealing member. As a result, problems such as breaking of the electrodes can be avoided. This construction is especially effective when the electrodes contain Ag.

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:
A PDP has first and second substrates which face each other with a space in between. A display electrode pair and a dielectric layer are formed on the first substrate, and a plurality of discharge cells are formed between the first and second substrates along the display electrode pair. In this construction, two or more depressions are provided in the dielectric layer in an area corresponding to each discharge cell. This improves luminous intensity and illumination efficiency. Also, to form the dielectric layer on the first substrate, first a transfer film is made by providing a dielectric precursor layer on a support film, then depressions are formed in the dielectric precursor layer of the transfer film, and lastly the dielectric precursor layer of the transfer film is transferred onto the first substrate. This decreases the number of manufacturing steps and increases the yield, thereby reducing manufacturing costs.
