    摘要: An apparatus for liquid phase epitaxial film growth includes a mother boat for supporting a substrate, a melt boat slidable on the mother boat for containing a melt and selectively bringing the substrate and the melt into contact, and a lid for opening and closing the melt boat. The mother boat is disposed in a quartz tube and push rods extend into the tube for sliding the lid to open and close the melt boat.

    摘要: A gas and humidity sensing element in a single integral structure made of a base plate of apatite ceramics, on which a particular metal oxide such as tin oxide, zinc oxide, or composite oxide of titanium and niobium is provided. The sensing element has a function of sensing gas and humidity with outstanding sensitivity to bad smell gas and alcoholic gas, in which the humidity is sensed and measured by variations in electrical resistance of the apatite ceramic base plate and the bad smell gas such as hydrogen sulfide, methyl mercaptan, etc. is sensed and measured by variations in electrical resistance of the metal oxide.
