摘要:
It is an object of the present invention to provide an inorganic filler, which effectively suppresses elution of A-site metals such as Ba, Ca, Sr, and Mg from a perovskite-type composite oxide and which can be particularly preferably used as an inorganic filler for a composite dielectric body. The inorganic filler of the present invention is characterized in that it comprises a perovskite-type composite oxide that has been coated by hydrolyzing a titanate coupling agent in a solvent. The pH of the inorganic filler is preferably 8.5 or less when it is dispersed in water, and the aforementioned solvent is preferably water.

A liquid crystal display device which can prevent the generation of bubbles on an adhesive surface between a liquid crystal display panel and a face plate which protects the liquid crystal display panel is provided. In mounting the face plate on an upper polarizer of the liquid crystal display panel by way of an adhesive material, a picture frame is formed on a periphery of the face plate for enhancing design property. Although the picture frame is formed by printing black ink, a quantity of Si present in the black ink is set to not more than 0.7% and not less than 0.01% thus preventing the generation of bubbles attributed to defective adhesion between the face plate and the adhesive material.

An analog semiconductor integrated circuit has an analog circuit, a PMOS and a bias adjustment circuit. The gate of the PMOS is the output section of an open drain system, and is connected to an internal node on the output side of the analog circuit. The bias adjustment circuit is connected to the internal node, and allows adjustment of the bias current in accordance with the fuse disconnection number. The relationship between the voltage when a fixed current flows to an input terminal and the fuse disconnection number that allows the optimum bias current to flow to the output section of the analog LSI is checked by using a plurality of sample analog LSIs having different threshold voltages. The voltage is measured by causing a fixed current to flow to the input terminal of a non-sample analog LSI, and the fuse disconnection number corresponding with this voltage is obtained. Thus, the fuses in the bias adjustment circuit are disconnected.
