摘要:
The present invention provides an oxide superconductor thick film which is formed on a substrate or a board and has a high Jc and Ic and a method for manufacturing the same. Predetermined amounts of materials containing elements of Bi, Pb, Sr, Ca and Cu are weighed, mixed and subjected to steps of calcining, milling, and drying, and thereafter an organic binder and an organic vehicle are added thereto to prepare a (Bi, Pb)2+aSr2Ca2Cu3Oz, superconductive paste, which is applied to the surface of a substrate or a board in a thickness of 260 &mgr;m or more and dried. Thereafter, the paste is first subjected to burning at temperatures of 835° C. to 840° C. for 100 hours, then pressurization, and further burning at temperatures of 835° C. to 840° C. for 100 hours, thereby preparing an oxide superconductor thick film having a film thickness of 130 &mgr;m or more having a high Jc and Ic.

An information recording and reproducing device includes an inorganic recording medium having at least one material selected from the group consisting of a phase change material, a shape changing material and a magnetic material. A conductive probe, which is proximate to or contacting a recording surface of the recording medium, is movable relative to the recording medium. Information is recorded by heating the recording medium in the area where the conductive probe is proximate or contacting to change a physical state therein. The area of the recording medium where the conductive probe is proximate or contacting is heated by applying voltage between the conductive probe and the recording medium.

A cantilever for an atomic force microscope, has a probe formed by a structure at least partially including a linear needle crystal. A method of manufacturing the cantilever comprises the steps of applying adhesive to a distal end portion of a cantilever body and placing on the adhesive, in a state where the cantilever body is held substantially horizontally, a structure having the shape of at least four needle crystals combined with one another so as to bond the structure to the distal end portion of the cantilever body.

A plasma display panel includes a front panel including a glass substrate, a display electrode formed thereon, a dielectric layer formed so as to cover the display electrode, and a protective layer formed on the dielectric layer; and a rear panel disposed facing the front panel so that discharge space is formed and including an address electrode formed in a direction intersecting the display electrode, and a barrier rib for partitioning the discharge space. The dielectric layer of the front panel contains bismuth oxide and calcium oxide without containing lead, and does not contain lead. The protective layer on the dielectric layer is formed by forming a base film on the second dielectric layer and attaching a plurality of crystal particles made of metal oxide to the base film so as to be distributed over an entire surface of the base film.

A plasma display panel (PDP) featuring the display performance of high definition display and a high brightness, and yet, a lower power consumption is disclosed. A front panel of this PDP includes display electrodes formed on a front glass substrate, a dielectric layer covering the display electrodes, and a protective layer formed on the dielectric layer. A rear panel of this PDP includes address electrodes formed along a direction intersecting with the display electrodes, and barrier ribs. The front panel and the rear panel confront each other to form a discharge space which is filled with discharge gas and is portioned by the barrier ribs. The protective layer is formed of a metal oxide made of MgO and CaO. X-ray diffraction analysis on the surface of the protective layer finds that the metal oxide has a peak between a diffraction angle where a peak of MgO occurs and a diffraction angle where a peak of CaO occurs along an identical orientation of the MgO peak.
