Title: Method for cutting flat glass and apparatus therefor
Inventor: TOMITA SATORU
IPC: C03B33/033
Filed: 1988-12-02
Abstract: PURPOSE:To enable cutting of a narrow glass plate by flawing one surface of the glass plate, pushing and moving the glass plate using a desired cutting position of the other surface of the flawed glass as an axial line. CONSTITUTION:One surface (1b) of a glass plate 1 engaged with a nipping groove 3 is located at a position facing to an edge (3a) of the groove 3. The position of the glass facing to the edge (3a) is a desired cutting position (2a). A supporting member 5 is then brought into contact with one surface (1a) of the bisected glass plate 1 to push and move the other piece (1B) of the glass plate 1 nipped with the groove 3 in the direction of an arrow (a). Thereby, the desired cutting position (2a) of the glass plate 1 is brought into contact with the edge (3a). If the glass plate 1 is subsequently pushed and moved, tensile stress is applied to the one glass surface (1a) using the desired cutting position (2a) in contact with the edge (3a) as an axial line. When the tensile stress attains the limit, the glass plate 1 is bisected into pieces (1A) and (1Ba) from a line (L) connecting the flaw 2 to the desired cutting position (2a) as a cutting line.

Abstract: PURPOSE:To prevent the breakdown of a moisture sensitive film in coating a resin, by wetting a moisture sensitive element with an organic solvent before applying resin liquid on the moisture sensitive element. CONSTITUTION:Before application of resin liquid, a gas component which is adsorbed in ceramic particles in a moisture sensitive film is removed. In order to remove the gas component, the film is wetted with an organic agent. It is desirable to use a solvent which is used for diluting resin liquid. Namely, the moisture sensitive element is immersed into the suitable solvent for appropriate time before coating. The solvent can be sufficiently applied on the surface of the element by a suitable method such as spraying. Thereafter, the coat of resin is given as quickly as possible. The coating is performed by a method such as immersion and spraying. Thereafter, the resin is dried for a specified time. Thus the coating is finished. In this element, having the moisture sensitive film, which is coated in this way, the film is not broken during treating and high water resistance and an excellent moisture sensitive characteristic are provided. Therefore, the breakdown of the moisture sensitive film can be prevented.

Title: Fuel assembly
Inventor: ISHII KAZUYA
IPC: G21C3/328
Filed: 1991-11-21
Abstract: PURPOSE:To make uniformary output distribution of a fuel assembly by reducing the average ratio of the fissionable Pu nuclear source in all the Pu isotope of the first from the outer side of the fuel assembly, to the other fuels. CONSTITUTION:A fuel assembly 1 is composed of four fuel rods 3 in which a Pu fuel having the ratio of the fissionable Pu nuclear source of 60% is loaded, and 56 fuel rods 4 in which a Pu fuel having the ratio of 70% is loaded, for example. Both the fuel rods 3 and 4 have the same enrichment of fissionable Pu, and made by enriching the natural U. By using the fuel rods 3 at the corners where the output is likely to be the highest, the neutron absorption there is increased, and the output can be reduced. As a result, the output peaking in the fuel assembly is reduced about 0.02, and the output distribution can be improved. And since the fissionable Pu enrichment at the central part is not increased, the fuel economy is not lost. Compared with a fuel assembly composed of only the fuel rods 4, the conversion ratio is increased, thereby the neutron infinite multiplication constant at the initial phase of combustion can be reduced.

IPC: G02B1/10
Filed: 1987-12-03
Abstract: PURPOSE:To form a uniform coating film on the vapor deposition surface of optical parts by circularly moving the optical parts while a coating liquid is held stuck thereto and rotating the optical parts themselves. CONSTITUTION:A revolving shaft 11 is rotated when a motor 12 is driven while the coating liquid such as ethyl silicate is held stuck to plastic lenses 16.

Abstract: PROBLEM TO BE SOLVED: To lessen curving which occurs at the time of sintering, by forming a ferrule blank molding into a cylindrical shape having an insertion hole for optical fiber and projectingly arranging an engaging part for hanging at its one end. SOLUTION: The ferrule blank molding 21 is formed by integrally molding a main body part 22 having the substantially cylindrical shape and the engaging part 23 projectingly arranged at its one end. The engaging part 23 is formed to a disk shape having the outside diameter larger than the outside diameter of the main body part 22 and is formed with a recessed part 24 at its end face. The insertion hole 25 for the optical fiber is opened along the longitudinal direction in the central part of the ferrule blank molding 21. The opening on the engaging part 23 side of the insertion hole 25 is formed as a tapered part 26 of the diameter gradually increasing to a tapered shape to facilitate the insertion of the optical fiber. The ferrule blank molding 21 is sintered to a sintered compact in the state of hanging the same by using the engaging part 23.  Since the ferrule blank molding is sintered by hanging the same, the bending at the time of sintering may be lessened. The engaging part 23 is thereafter removed and the sintered compact is subjected to required polishing to obtain the ferrule.
