Abstract: The present invention provides a radiant tube supporting apparatus for a radiant tube arranged as a radiant heat source in a heat treatment furnace. The radiant tube is inserted through a furnace wall on one side having a supporting member attached to a bend at the tip of the radiant tube. The supporting member projects to outside the furnace through the furnace wall on the other side, and a bearing member bearing the supporting member is provided outside the furnace.

Abstract: An ophthalmologic apparatus comprises a measuring instrument (1) for measuring a subject's eye and an ophthalmologic-data forming instrument (2) for forming ophthalmologic data which is obtained by adding kind data showing the kind of the measuring instrument (1) to measurement data measured by the measuring instrument (1). The ophthalmologic-data forming instrument (2) comprises a memory (2c) for storing the measurement data, a memory (2b) for storing the kind data, and a control unit (2a) for forming and outputting the ophthalmologic data from the data stored in the memories (2b, 2c).

Abstract: A corneal shape measuring apparatus includes a system 1 for concentrically projecting a plurality of ring images 6 onto a cornea C, a system 3 for receiving the ring images 6 projected onto the cornea C, and a multipoint detecting circuit 9 and a light emission controlling circuit 10 each for avoiding the overlap of adjacent ring images of the ring images 6 projected onto the cornea C.

Abstract: A method of dissolving zinc oxide in which, to perform continuous zinc-system electroplating of a steel sheet using an insoluble anode, particularly continuous zinc-nickel alloy electroplating, a dissolution bath is provided in a circuit for a sulfuric acid plating liquid, and zinc oxide is dissolved in the plating liquid in the dissolution bath. The amount of zinc oxide thrown in is controlled during dissolution of zinc oxide so that the pH of the plating liquid at an outlet of the dissolution bath does not exceed 2.3.

Abstract: An apparatus for continuously dissolving metal powder for use in plating includes a dissolving tank for dissolving metal powder for used in plating solution in a solvent, a filter for separating the solution containing undissolved residue into an undissolved residue and a filtrate, a recovery tank of the filtrate, and a plating solution storing tank for supplying recovered filtrate to a plating tank. The filter is a porous substance having a plurality of liquid passages in the axial direction thereof, and the filter is provided with a circuit for returning a liquid solution containing the undissolved residue passed through the passages to the dissolving tank and a pipeline for leading the filtrate to the recovery tank.A method of dissolving a nickel metal, which has a specific surface of 0.003 m.sup.2 /g or more, is dissolved with the use of the above-described apparatus.

Abstract: This invention provides an ophthalmological image processing system which can avoid data errors when processing images by appending data to identify a subject's left and right eyes, and other photographic condition data. The system comprises an ophthalmological camera for electronically obtaining an image of a subject's eyes, inputting means for inputting photographic condition data, and processing means for linking a fundus image obtained by the ophthalmological camera to the photographic condition data input by the inputting means.

Abstract: Green plant leaves (herbs) are blanched with an aqueous medium having a pH of 6.5 to 11 and heated at a temperature of 80.degree. to 102.degree. C. The reverse surfaces of the blanched herbs and/or the upper surfaces of dough sheet units are coated with an aqueous coating medium such as an aqueous solution of pullulan or gelatin, followed by attachment of the herbs to the dough sheet units. The dough sheet units-cum-herb(s) are baked to produce baked confectionery products with a bright green herb(s) free from the grassy smell and hardly liable to be discolored. The dough sheet units may be either of a single-layer structure or of a multi-layer structure including a vegetable-containing layer(s). According to the foregoing process, biscuits, pies, crackers, bread, etc. with a healthy touch can be produced.

Abstract: A fast breeder reactor has a nuclear reactor container filled with a liquid metal, a reactor core disposed within the nuclear reactor container, and a first supporting structural member which is mounted to the nuclear reactor container such as to support the reactor core. The fast breeder reactor is provided with a cylindrical structural member which surrounds the periphery of the reactor core such as to define an annular gap between the cylindrical structural member and the reactor core for allowing the liquid metal to exist therein, the cylindrical structural member being mounted to the nuclear reactor container by means of a second supporting structural member. The inertial resisting force produced when the liquid metal existing in the annular gap will flow out from the annular gap in response to the vibration of the reactor core acts such as to suppress the vibration of the reactor core, thereby allowing an improvement in the anti-vibration properties of the fast breeder reactor.
