Abstract: A coiled component (K1) having an insulating member (3) and a conductive member (5). The conductive member is provided in the insulating member (3) and has a plurality of turns which are gradually different, in diameter, from each other from one end towards the other end of the conductive member (5) such that at least the turns of the conductive member (5) are disposed in different planes, respectively. Also, a magnetic layer (8, 9) is provided on at least one of upper and lower faces of the insulating member (3).

Abstract: The present invention relates to ceramics and a method for making ceramics having very little dimensional change after sintering and high dimensional accuracies, so that the characteristics of inorganic functional material are fully maintained and utilized. The ceramics of the present invention comprise grains of inorganic functional material and grains of complex oxide. The pores existing between said grains of inorganic functional material are filled with said grains of complex oxide produced by a sintering reaction between an oxidized metal and an inorganic compound.

Abstract: The invention relates to a magnetic material and a method of manufacturing the same. An objective of the invention resides in providing a magnetic material whose dimensional change rate after sintering is low and whose magnetic property is not deteriorated. In order to achieve the objective, a magnetic material according to the invention comprises a great number of ferrite grains (1) which are formed by sintering ferrite raw powder, and shrinkage preventing grains (2) which are interposed among these plural ferrite grains (1) and which are sintered with the ferrite grains (1) in contact with the outer peripheries thereof and are also oxidized with oxygen so as to change into ferrite when they are sintered.

Abstract: A composite ferrite material is provided. The composite ferrite material obtained from a mixture of a magnetic ferrite powder with high crystallinity, prepared by firing at a prescribed temperature, and a glass powder, having a softening temperature lower than said firing temperature, by heat treatment of said mixture at a temperature which is higher than, or equal to said softening temperature of said glass powder and lower than, or equal to said firing temperature, to effect the binding of said magnetic ferrite powder by said glass material. The composite ferrite material has excellent magnetic characteristics and can be obtained in a form of the desired dimensions with high accuracy.

Abstract: 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.
