Title: Cam barrel, optical system drive assembly and optical apparatus
Inventor: OGAWA YUKIO
IPC: G02B7/04
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily manufacture a small-diameter cam barrel by combining plural curved surface members which have arcuate shapes in their sections in optical axis direction view and are formed with cam shafts to a cylindrical form, thereby constituting the cam barrel. SOLUTION: The curved surface members 1 are formed to the arcuate shapes in their sectional shapes in the optical axis direction view and cam grooves 2 and 3 (3a and 3b) are formed on their inside surfaces. These curved surface members 1 are so formed that the shape over the entire part inclusive of the cam grooves 2 and 3 (3a and 3b) is the same. The curved surface members 1 are combined and are formed to the cylindrical shape, by which an integral cam ring is constituted. When the cam ring is assembled, the three curved surface members 1 are combined to the cylindrical shape and are adhered while cam pins 6a to 6c and 7a to 7c of lens holding frames 6 and 7 are engaged with the cam grooves 2, 3.  Since the respective curved surface members l merely have the arcuate members, the cam ring formed with the cam grooves of an arbitrary type may be easily manufactured while the diameter is reduced.

Abstract: PURPOSE:To enhance the ionization rate of evaporating particles and to form a good film on a substrate having high adhesive strength by disposing an electrode between the vapor source and substrate in a bell-jar and impressing high- frequency electric power and low-frequency electric power to the electrode. CONSTITUTION:The inside of the bell-jar A is evacuated to a high vacuum state of about 10<-7> by an evacuating means 6 and thereafter an inert gas is supplied thereto from an inert gas supplying means 5 to about 10<-4>-10<-5>. A high-frequency power source 8 and a commercial frequency power source 9 are then operated to impress superposedly high-frequency electric power (about 13.56MHz) and commercial electric power (about 50-60Hz) to the electrode. An electron beam is at the same time applied from an electron gun 4 to the material for evaporation in a crucible 3 to evaporate said material. The evaporating particles are ionized in the electric discharge region around a coil 7 and are oscillated at a high speed by the high-frequency electric field. The ions are largely moved and oscillated by the commercial frequency electric field. The evaporating particles are thus accelerated in ionization and adhered to the substrate 1, thereby forming a good film thereon.
