    摘要: An epitaxial growing apparatus comprises a base plate, a quartz bell jar mounted on the base plate, and a reaction chamber defined by the base plate and the quartz bell jar, in which an epitaxial thin film layer of a semiconductor substance is formed on the substrate mounted on a support member. A metal bell jar is disposed outside the quartz bell jar so as to surround the quartz bell jar and a plurality of engaging members are operatively connected to the metal bell jar for detachably engaging the metal bell jar with the quartz bell jar.

    摘要: A graphic input device for converting a character, a diagram or like pattern entered by hand to an electric signal. A pen for entering the pattern has a winding therein which is fixed in a predetermined position which is not close to the tip of the pen. This allows a minimum of error due to inclination of the pen to be introduced into a value which is indicated by a coordinate signal when the pattern is entered.
