Abstract: PURPOSE:To obtain a lens holder which facilitates the fine adjustment of lens barrels, has good workability and decreases the man-hours for assembly by providing a gear in the outside circumferential part of the split lens barrels and a positioning means for positioning the gear relative to the split lens barrels. CONSTITUTION:The split lens barrels 20, 21 which have holding grooves for holding plural pieces of lenses 22-26 on the inside surface and are bisected, the gear 32 having a hole part which can be fitted to the outside circumferential part of the split lens barrels and the positioning means which positions the gear relative to the split lens barrels are provided to this lens holder. The lens holder has also an outside frame 39 which has even lines of external screw threads 41 provided in the outside circumferential part of the split lens barrel and even lines of internal screw threads 40 screwing to even lines of the external screw threads and holds the split lens barrel and an energizing means which energizes the split lens barrels in the optical axis direction toward the outside frame. The rotating angle of the gear and the moving quantity of the lens barrels are, therefore, directly proportional to each other if the gear 32 is driven. The optimum position of back focus can be thereby found and the accuracy of the adjustment is improved. Since the independent insertion of the lenses to the bisected lens barrel is possible at the time of inserting the lenses to the lens barrels, the assembly is facilitated and the man-hours for the assembly is decreased.

The alloy may contain 0.1W10% of one or more of Mn, Y, Cu, Zn, Al, C, rare earth metals, Ru, Rh, Pd, Os, Ir and Pt as additional component(s). Its complex magnetic property is obtained by solution-treating the alloy in an α+γ dual phase zone and utilizing the spinodal decomposition of each phase, a γ→α' transition mechanism and an age-precipitation-hardening mechanism so that mainly α contributes to a large coercive force while γ contriutes to a small coercive force. Thus, the magnetic alloy abound in mass-producibility is obtained at a low cost.

Abstract: PURPOSE:To achieve the good-reproductivity gas-phase growth of the thin film of good-quality metal or metallic compound by coating the inner wall of a tube reactor with an Si thin film in advance and laminating a film of metal or metallic compound on the surface. CONSTITUTION:A cleaned crystal tube reactor 1 and a boat 9 are put in a furnace and are heated at 550-700 deg.C, after which the reactor 1 is reduced the pressure and SiH4 is introduced to coat the inner wall of the reactor and the surface of the boat with Si21 of 0.5-2mum. The temperature inside the furnace is kept at 300-500 deg.C and the reactor 1 is reduced the pressure. Then WF6+H2 is introduced to coat the whole surface of the Si layer 21 over the inner wall of the reactor and the boat with a W film 2 of 0.1-1mum thick. In this constitution, the tightness of the contact of the metallic film or the metallic compound film with the crystal tube reactors is indirectly enhanced by the Si and the coated film over the inner wall of the reactor does not peel off even if substrates 8 are set on the boat 9 and the growth of W film over the substrate 8 is repeated. In addition, as the condition around the substrate does not change during the formation of the film, the predetermined thin film can be formed with a good reproductivity.
