摘要:
A method for fabricating ceramic electronic parts allows external electrodes to be baked onto the electronic parts without overlaying powder on the sagger. An adhesive material layer is provided on a surface of a sagger on which electronic parts are placed. The sagger is inserted into a firing oven with the electronic parts adhesively fixed onto the adhesive material layer, whereby the external electrodes of the electronic parts are baked. The adhesive layer burns away during the firing process. The method including such steps eliminates the need of overlaying powder onto the sagger, so that no powder sticks to the external electrodes after baking, so that the process of removing powder is no longer necessitated.

A highly reliable multi-layer ceramic electronic part in which is compact, in which cracks tend not to occur in the ceramic element even in cases where it is handled in bulk by a chip mounting device. A plurality of electrodes (internal electrodes) are disposed within a ceramic element whose length L.ltoreq.1.0 mm, height H.ltoreq.0.5 mm and width W.ltoreq.0.5 mm. The thickness t.sub.1 of a ceramic outer layer portion of the multi-layer ceramic electronic part, is 0.15 mm or less. The thickness of the ceramic outer layer portion t.sub.1 and the thickness t.sub.2 of the portion where the internal electrodes are disposed have the relationship 1/4 t.sub.2 .ltoreq.t.sub.1.ltoreq.1/3 t.sub.2.

A highly reliable ceramic electronic part that can be reliably attracted by a vacuum attraction type nozzle without inviting cracks or breaks. The ceramic electronic part comprises a ceramic body and external electrodes attached around the end surfaces of the ceramic body. The ceramic body has a length (L).ltoreq.1.0 mm, a height (H).ltoreq.0.5 mm, and a width.ltoreq.0.5 mm. The external electrodes have rounded portions extending from the end surfaces of the ceramic body to their adjacent outer surfaces of the ceramic body. The thickness t of these rounded portions is set so that t.ltoreq.10 .mu.m and t.ltoreq.H/30. The thickness t of these rounded portions may further be set so that t.ltoreq.W/30.

摘要:
A laminate is prepared in which adjacent internal electrodes are electrically insulated from each other at an end surface at which the internal electrodes are exposed, a space between the adjacent internal electrodes, which is measured in the thickness direction of insulating layers, is about 10 μm or less, and a withdrawn distance of the adjacent internal electrodes from the end surface is about 1 μm or less. In an electroplating step, electroplating deposits deposited on the ends of the adjacent internal electrodes are grown so as to be connected to each other.

A phosphor screen which has an optical fiber plate formed of a number of bundled single optical fibers, each of which fibers consists essentially of a cylindrical core and a clad surrounding the curved peripheral wall of the core and a phosphor layer formed on one surface of the optical fiber plate, characterized in that the cylindrical core on the other surface of the optical fiber plate is removed, to provide a depression of a depth of at least 1 .mu.m, thereby producing an image having high contrast.
摘要:
The monolithic ceramic electronic component includes a first external electrode 5, a second external electrode 6, and a ceramic sintered compact 4 including internal electrodes 2 and 3, the first and second external electrodes 5 and 6 being disposed on both end faces 4a and 4b of the ceramic sintered compact 4. The first and second external electrodes 5 and 6 have a multilayer structure in which sintered electrode layers 5a and 6a, intermediate electroplated layers 5b and 6b, and plated layers 5c and 6c are arranged in that order. Exposed surface regions 7a of insulating oxides 7 are exposed from the outer faces of the sintered electrode layers 5a and 6a, the oxides 7 being derived from a glass frit contained in the sintered electrode layers. Metals 8 are deposited on the exposed surface regions 7a and the intermediate electroplated layers 5b and 6b are then formed by electroplating.

The present invention provides an X-ray image detector (1) which can reduce the size of a whole apparatus associated with an X-ray imaging tube, reduce noise components of an output X-ray image even if an incident X-ray is very weak, and provide a distortion-free visible image or electric image. The X-ray image detector (1) comprises a vacuum container having an input fluorescent screen outputting fluorescent light, a photoelectric screen converting the fluorescent light which is output from the input fluorescent screen to a photoelectron, and an output fluorescent screen outputting a visible light image with the obtained electron, a plurality of image pick-up elements (3) arranged such that partially overlapped areas are outside an image taking area and taking the visible light image in a divided way, image processing circuits (4) so arranged as to correspond to the image pick-up elements and trimming a taken video signal, an output image processing circuit (6) obtaining a composed image and a display device (5) displaying it as one signal.

摘要:
A laminate is prepared in which adjacent internal electrodes are electrically insulated from each other at an end surface at which the internal electrodes are exposed, a space between the adjacent internal electrodes, which is measured in the thickness direction of insulating layers, is about 10 μm or less when a withdrawn distance of the adjacent internal electrodes from the end surface is about 1 μm or less, and is about 20 μm or less when a protruding length of the adjacent internal electrodes from the end surface is at least about 0.1 μm. In an electroplating step, electroplating deposits deposited on the ends of the adjacent internal electrodes are grown so as to be connected to each other.
