    摘要: A silica glass filter comprises a porous support body composed of amorphous silica particles as a porous sintered body and having a purity of 99.9% or more and containing 150 ppm or less in total of impurities including alkali, alkali metal, heavy metal and/or elements of III B group, and a filtration layer formed on the support body. The filtration layer is composed of amorphous silica particles as a porous sintered body in a fine mode and has substantially the same purity as that of the support body.

    摘要: In a semiconductor sensor, the surfaces of first and second semiconductor substractes of a first conductivity type are made into flat surfaces by polishing the surfaces and are contacted each other so that the both substrates are bonded together. Source and claim regions are formed by diffusing an impurity of second conductivity type. The source and claim regions are separated through a through hole formed in the second substrate and are extended along the surface of the second substrate. An insulative layer is formed on the opposite surface of the second substrate and an inner surface of the through hole.

    摘要: A flat display device comprises a vacuum envelope constituted by a back base plate consisting of an elastic metal plate and a display panel and accommodating a thermionic cathode structure and a plurality of electrode structures for controlling the electron beams emitted from the thermionic cathode structure. The thermionic cathode structure is divided into a plurality of sections each including a plurality of coiled thermionic cathode heaters connected in parallel and arranged such that each corresponds to each of picture element regions provided on the back side of the display panel. Voltage supply terminals for supplying power to the parallel coiled heaters in each section are led out through the back base plate via insulating members.
