IPC: C03C13/04
Filed: 1982-01-22
Abstract: PURPOSE:To obtain the titled multi-or single-mode preform, having stepwise refractive index distribution, extremely easily, by rotating a longitudinally separable mold, and pouring the molten fluoride glass for clad and the one for core successively into the cylindrical hollow part of the mold. CONSTITUTION:The outer frame 1 of the mold is composed of e.g. three pieces of longitudinally separable semimetallic or metallic members 2, 2' and 2'' which are tightly bound together by the ring 3 and closed with the bottom plate 4 at the bottom to form a hollow part 5. The mold 6 is heated at about 300 deg.C, fixed to the center axis of the rotating table 8 with chucks 7, 7' and rotated with the motor 10. The molten fluoride glass for clad is poured from a gold crucible into the hollow part 5. The mold is removed from the table, and the unsolidified glass at the central part of the hollow is poured out of the mold to leave a glass tube. The tube is fixed to the table, rotated, and without delay, a molten fluoride glass for core having high refractive index is poured into the cavity, and annealed for a long time. After annealing, the mold is cooled in the furnace to normal temperature, and the outer frame is removed from the mold to obtain the objective preform. As an alternative method, the mold is rotated at high speed to form the molten glass for clad in the form of tube by the centrifugal force, and the molten core glass is poured in the tube.

IPC: B22D11/06
Filed: 1986-01-17
Abstract: PURPOSE:To obtain a thin continuous strip stock having high magnetic characteristics with a single stage by providing a magnetic circuit near a melt ejection part and impressing a magnetic field in the radial direction of a roll. CONSTITUTION:A magnetic yoke 18 acts as an electromagnet and a magnetic field is formed in the radial direction of the roll 10 between the magnetic yoke 18 and the roll surface when a DC power source is connected to a coil 20. The melt 22 of a magnetic material is quickly cooled by the roll surface and solidifies past the Curie point when the melt 22 is injected from a melting crucible 16 onto the roll 10 surface. Since the magnetic circuit is provided to the position where the melt lowers nearly to the Curie point the melt 22 is cooled and is at the same time affected by the magnetic field by which the melt is oriented in the thickness direction and is cooled to solidify as it is. The thin continuous belt-like magnetic material 24 oriented in the thickness direction is thus obtd.

Filed: 1986-01-17
Abstract: PURPOSE:To prevent pink-eye effect and a failure in tone reproduction from occurring during flash photography by providing a filter which enters the optical path of a photographic lens during short-distance flash photography. CONSTITUTION:When an object distance is <=4m, an iron piece 11d is attracted by an electromagnet 13 and a lock claw 11b disengages from the projection part 5c of a polarizing filter 5, thereby unlocking the polarizing filter 5. A gear 6 is therefore rotated clockwise and a gear 4b is rotated counterclockwise, so the polarizing filter 4 enters the optical path of a flash device light emission part 2. Light emitted from the light emission part 2 of the flash device to an object is passed through the filter 4 and light which is reflected by the object and reaches a film surface is further transmitted through the polarizing filter 5. Consequently, neither pink-eye effect nor a failure in tone reproduction is caused even during short-distance flash photography.

Abstract: PURPOSE:To make it possible to sense the temperature on the surface of an object and the speed of its movement by applying magnetic flux to a magnetic band plate in its transversal direction and sensing the magnitude of magnetic flux that penetrates the plate. CONSTITUTION:Magnetic flux by a permanent magnet 9 in a pick up 80 is divided into the magnetic flux that flows into a metallic composite band 50 on a rotating body and the magnetic flux or that flows into an electro-magnetic conversion element 10 by means of a yoke 8. At the time the amount of the magnetic flux flowing into the metallic composite band 50 from the yoke 8 depends on whether the temperature of a temperature sensing magnetic band is under or over its Curie point, and further whether or not the yoke 8 is positioned opposite the punched hole 7 of the metallic composite band 50. By the way, the composite band 50 comprises the temperature sensing magnetic band 5 and a highly magnetic band 6 that has Curie point that is higher enough than the magnetic band, both being pasted together. With this arrangement it becomes possible to sense the speed of movement of the surface of a body and its surface temperature.

IPC: G01M11/02
Filed: 1987-01-17
Abstract: A method for evaluating the in vivo ability of a contact lens to become or remain wet includes the steps of supporting the subject's head to determine a fixed orientation of the lens, illuminating the lens with coherent light, imaging the pre-lens tear film in a manner to form an interference pattern, recording in a time sequence manner the image formed thereby, and determining the tear film thickness by correlating the interference bands of the recorded image. The classical contact angle is derived, and other measures, such as the time interval from blink until the onset of tear film breakup, or the time until the film evaporates, and the initial or average film thickness are derived. In addition, the nature and evolution of localized dry spots may be directly observed, clarifying the causes of tear film breakdown on worn contact lenses. The invention enables wetting characteristics to be evaluated as they are affected by lens material, lens aging and lens soiling, as well as the evaluation of solvents, additives and cleaners, for their effects on wetting characteristics.Apparatus for performing the method includes means for supporting the head so as to determine a fixed location of the contact lens (8), a coherent light source (9), and a camera (19) focused at the pre-lens film from a position to image light from the source specularly reflected from the front and rear surfaces of the tear film. A film motion analyzer (50) provides numerical coordinates of interference bands, and a microprocessor (60) analyses the coordinates to provide a quantitative measure of lens position or wetting characteristics.
