Abstract: PURPOSE:To obtain an excellent lining resistant to hydrofluoric acid in a treating apparatus for a combustion exhaust gas of coal by laminating a compound layer contg. 5-50wt% gamma-Al2O3 particle on the surface of a base material consisting of the fiber reinforced plastic. CONSTITUTION:A compound layer 2 consisting of alpha-Al2O3 particle, 5-50wt% gamma-Al2O3 particle and the resin resistant to corrosion is laminated with a spray or the like on the surface of a base material 1 consisting of the fiber reinforced plastic of the resin resistant to corrosion such as unsaturated polyester resin. Still further, gamma-Al2O3 particles function as an absorbent of F2 and alpha-Al2O3 particles function as an excipien. An average particle size of the inorganic particle is 60-90mu and the thickness of the layer is suitably decided by means of the amount of F2 incorporated in the exhaust gas and a waste liquid. In an example wherein a lining having 0.25mm thickness was laminated and brought into contact with hydrofluoric acid of 10,000ppm fluorine concn. for 180 days, fluorine had not reached the base material.

Abstract: PURPOSE:To realize a highly sensitive position sensor without increasing the number of parts by making the incident light side of a galvano-mirror into a half mirror, and providing a lens means on the back side of it, and leading light converged by the lens means to a bi-sected detector. CONSTITUTION:This position sensor is for a tracking actuator which detects the turning angle of the galvano-mirror 2, and controls a voice coil motor for moving an optical head so that the turning angle of the galvano-mirror 2 comes to a neutral angle while it controls the rotational angle of the galvano-mirror 2 by a tracking error signal detected by a photodetector 3. The light transmitted through the half mirror 21 of the front side of the galvano-mirror 2 is converged by the lens means 22 at its back side, and forms a spot P1 on the bi-sected detector 3. The spot P1 moves in proportion to the turning angle of the galvano- mirror 2. By determining distance D between the detector 3 and the mirror 2 so that the fitting position of the detector 3 comes to the neighborhood of the converged point of the light, the detection of high sensitivity can be realized.
