    摘要: A furnace for manufacturing ceramics is disclosed. The furnace contains a cylindrical heat resistant container, a furnace body for heating the cylindrical heat resistant container, and driving means for driving the cylindrical heat resistant container. The cylindrical heat resistant container rotates about a central shaft. At the same time, a first end and alternately a second end of the cylindrical heat resistant container are raised and lowered periodically, thus creating a seesaw motion while any material contained in the cylindrical heat resistant container is fired by the furnace body.

    摘要: The present invention provides a semiconductor-type laminated ceramic capacitor with a grain boundary-insulated structure made of Sr.sub.(1-x) Ba.sub.x TiO.sub.3 as a main component, comprising the functions of a conventional capacitor which absorbs low voltage noises and high frequency noises, and a varistor when high voltage noises and electrostatic charges invade, wherein simultaneous sintering of the materials of ceramic capacitor together with the materials of inner electrodes was made possible in the manufacturing process. Besides a material to be made semiconductive is added to the main component of Sr.sub.(1-x) Ba.sub.x TiO.sub.3 with excess Ti, the materials of Mn-Si, which are converted to MnO.sub.2 and SiO.sub.2 in the sintering process, are also added to the main component. According to the manufacturing method of the present invention, calcination process of laminated raw sheets prevents troubles occurring in laminated ceramic capacitors with varistor function, comprising: breaks of electric connections in inner electrodes; de-lamination of ceramic sheet; cracks in ceramic sheet; decrease of sintering density; and non-uniformity in the texture of sintered body. It improves electric characteristics, i.e. capacitance, voltage non-linearity coefficient .alpha. and varistor voltage, and is reliable. The present invention provides two major advantages in the composition of materials and in the manufacturing process.
