C. or less. The synthetic powder thus obtained is added to 100 parts by weight of ZnO material powder to produce ceramics. By using the ceramics for a zinc oxide varistor, a zinc oxide varistor for a low or high voltage can be produced in high yield, which can be sintered at a low temperature and is excellent in electric characteristics and reliability upon DC loading and surge. Aluminum is sprayed on both sides of a sintered body so that an aluminum layer is formed. Copper is sprayed on the aluminum layer so that an electrode is formed. A lead wire is bonded to the electrode. Then, portions of the molded bodies other than the lead wire are coated and insulated so that the zinc oxide varistor can be obtained.

摘要： By performing a debinder process before or at the time of firing, and by enhancing a programming rate in the temperature range of 650.degree..about.950.degree. C., the size of particles shows less distribution. Also, when the temperature comprising the particle growth range of 1025.degree..about.1200.degree. C. is maintained for many hours, a zinc oxide varistor having relatively large and uniformly formed particles can be provided. When a zinc oxide varistor compound is fired, a solid solution of zinc oxide spinel is fired at the programming rate of 175.degree. to 500.degree. C./hr in the temperature range comprising the primary phase of from 650.degree. to 950.degree. C., and at the programming rate of 30.degree. to 500.degree. C./hr in the range of from 1250.degree. to 1300.degree. C. Accordingly, a zinc oxide varistor having comparatively large and uniformed formed particles can be obtained. Sintered products obtained in this way show less distribution in operating voltage.

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： Here disclosed is an ink jet apparatus having an ink-circulating/dispersing function. The apparatus provides ink with dispersion as required, and circulates the ink through a tube to an ink-collecting tank. During this circulation, a required amount of the ink is fed to a printer head to form a predetermined pattern on a surface of a substrate. By virtue of the circulating/dispersing function, the apparatus can cope well with easy-to-aggregate ink having poor stability in terms of printing, thereby protecting a printer head or an ink-spouting section from clogging during ink jet printing. Such stabilized ink jet printing contributes to manufacturing highly reliable electronic components with an increased yield of products.
