Abstract: PURPOSE:To provide corrosion resistance which make it possible to melt highly corrosive metals at a high temperature by flame-spraying a corrosion resistant ceramic material to attach it to a required wall thickness for crucible round a body material which is formed in the shape of a crucible by weaving metal fibers or carbon fibers in the fashion of a net. CONSTITUTION:A metal fiber, for instance, a tungsten fiber 18 is woven in the fashion of net so as to form the shape of crucible as a whole to make a body material. To this body material a ceramic, for instance, zirconia, yttria, or alumina 19 is flame-sprayed to the thickness which is the thickness of crucible, constituting thereby a crucible. The ceramic material 19 is in direct contact with a molten metal 19 which is highly corrosive and the molten metal is not in direct contact with the body material. On the other hand the body material is excellent in strength and toughness and secures the shape of the whole crucible so that it plays the role of keeping the ceramic material 19 from crumbling into pieces. Because the body material is in the fashion of net, the ceramic material attaches well to this and held firmly to it, and the crucible as a whole is excellent in corrosion resistance and in toughness at high temperature.

Abstract: PURPOSE:To prevent a malfunction of an automatic focusing device by using plural BPFs by continuing the control until the output of the 1st BPF exceeds a prescribed level with discrimination outputs of other BPFs while the output of the 1st BPF is kept under the prescribed level. CONSTITUTION:When the peak output level of the 1st BPF7 is less than a prescribed level in a large out-of-focus state, the output of a level detecting circuit 14 is set at ''0''. Then analog switches 15 and 18 are turned on at the (b) side. Therefore the output of the second BPF13 is supplied to reference frequency component detecting circuit 8, and the component of the extracted reference frequency is compared with the reference signal of a reference frequency signal source 10 in terms of phase. This output of comparison is averaged by an LPF 16 and generates a DC offset of adverse characteristics. This DC offset is discriminated as a binary form by a binary discriminating circuit 17. Then a lens is shifted in the focusing direction via a motor driving circuit 11. When the lens moves close to the focusing point and the output of the BPF7 exceeds a prescribed level, the output of the circuit 14 is set at ''0''. Then the switches 15 and 18 are turned on at the (a) side. A closed loop is formed with use of the output of the BPF7.
