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.

The invention presents a manufacturing method of laminated substrate capable of realizing small size of portable electronic appliances. Prepreg 141 is a thermosetting resin which holds a plate form in first temperature range, has a thermal fluidity in second temperature range, and is cured in third temperature range, and integrating process (118) includes softening (120) of heating prepreg (141) to second temperature range, and softening the resin impregnated in prepreg (141), forced flowing (122) of compressing prepreg (141) before prepreg (141) comes to third temperature range, and forcing the resin to flow into space and gap formed among semiconductor (105), resistor (106), and substrate (101), and hardening (123) of heating prepreg (141) to third temperature range. As a result, without using intermediate material, space and gap formed among semiconductor (105), resistor (106), and substrate (101) can be securely filled with resin.

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.

A channel switching system includes two microvalves i.e. a first valve (stopper valve) and a second valve (water retaining valve). The first valve is openable and closable, and the second valve is operable to block fluid flow by a surface tension force. Changing the first valve from an open state to a close state enables to switch the system from a condition that the fluid flows through the channel where the first valve is mounted by blocking the flow at the second valve by the surface tension force to a condition that the fluid flows through the channel where the second valve is mounted by releasing the system from the condition that the flow is blocked at the second valve by the surface tension force.
