    摘要： A method for manufacturing varistor by which a varistor having a high plating resistance and a high moisture resistance is manufactured by selectively forming a compact high-resistance layer having a uniform thickness on the surface of a varistor element. In the method, the varistor element (1) is first formed by alternately laminating ceramic sheets (1a) mainly of a zinc oxide and internal electrodes (2) upon one another, and then, Ag electrode paste which becomes external electrodes (3) is applied to both end faces of the element (1). Then, after the element (1) is sintered through heat treatment, the element (1) is buried in SiO2 or a mixture (5) containing SiO2 and the element (1) is heat-treated for 5-10 minutes at 600-950° C. in the air or in an oxygen atmosphere.

    摘要： The varistor element contains zinc-oxide as a main constituent and at least bismuth and antimony as accessory constituents. The content of bismuth in the form of Bi.sub.2 O.sub.3 is in a range from about 0.1 to 4.0 mol % and the content of antimony in the form of Sb.sub.2 O.sub.3 constitutes a mol-ratio of Sb.sub.2 O.sub.3 /Bi.sub.2 O.sub.3 less than or equal to about 1.0 mol %. These materials are mixed thoroughly and are pressed into a compact. After coating both sides of the compact with Ag or Ag--Pd paste, the compact and its electrodes are sintered simultaneously at a temperature of about 800.degree. C. to 960.degree. C.

    摘要： The invention is directed to a method of firing ceramics and a furnace for manufacturing ceramics. Ceramic forms are first fired in a cylindrical heat resistant container in a furnace core tube by using a lateral tubular furnace to increase their mechanical strength. Then, the container is rotated while the ceramic forms are fired further in a predetermined temperature region, which includes a maximum temperature. In this manner the ceramic forms are heated in a uniform state, both thermally and atmospherically, while receiving moderate impact by rotation, and defective appearance and fluctuations in the characteristics of the ceramics are suppressed. In particular, the container is rotated within a temperature region which is higher than the temperature used to start increasing the mechanical strength of the ceramic forms. Further, the ceramic forms can be packed into the container at a higher rate during the rotation portion of the process than during the first firing.

    摘要： A large number of liquid crystal display devices is formed on a single plane, each of the liquid crystal display devices being formed by arranging liquid crystal between transparent substrates which allow light from a light source to pass through. Display portions of the respective liquid crystal display devices are covered by a masking member (23) and a light guide which is formed of light guide devices, one or more of which being provided for each of said liquid crystal display devices, and junctions between the liquid crystal display devices are also covered by the light guide. With this structure, when the light guides are formed such that the junctions between the plurality of liquid crystal display devices are also covered, lattice-like non-display lines do not appear, thereby providing substantially visually uniform brightness throughout the entire screen of the large-sized liquid crystal display and improving the entire image.
