Title: Photo multiple distributor
Inventor: SAITOU MASAMITSU
IPC: G02B27/10
Filed: 1978-06-30
Abstract: PURPOSE: To distribute the light in a single optical fiber into each optical fiber and to increase the degree of light bonding, by increasing the light bonding between optical fibers bundled without inserting optical parts such as mixer rods between input and output optical fibers.  
     CONSTITUTION: A plurality of optical fibers 12 are heated, twisted, and boundled into a thin strand to form a light bonding part 13. Photo input 14 propagated through one optical fiber is bonded with each optical fiber at the light bonding part 13 and distributed to be propagated as photo outputs 15 to 18. Thus, by bundling into a small diameter while heating and twisting an optical fiber bundle, the bundling of optical fibers becomes excellent and each core may be adjacent to each other. Also, by applying twists, the light intensity distribution becomes wider. In addition, since the flexibility is increased by bundling into a small diameter, even if a long light bonding part 13 is formed, it can be wound around a cylinder 27 so that the size can be reduced. Thus, a long light bonding degree may be obtained, and the light bonding degree between optical fibers may be enhanced.

Abstract: PURPOSE:To improve the flatness of a window member made of Be, by using alloy whose thermal expansion coefficient is in the range of 7-13X10<-6>/ deg.C as frame member. CONSTITUTION:A window member 2 is constituted of Be. A frame member 3 is constituted of alloy whose thermal expansion coefficient is in the range of 7-13X10<-6>/ deg.C. For example, said alloy is composed of 36wt.% of Ni and residue of Fe or 40-55wt.% of Ni and residue of Fe. A bonding material layer 4 is interposed between the widow member 2 and the frame member 3. Soft metal whose melting point is not so high, like Ag, In-Ag, Cu, Al, Ni and Au is used in the bonding material layer 4. Thereby excessive compression stress and excessive tensile stress are not applied to the window member 3 at the time of cooling after the bonding of the window member 3 and the frame member 2, so that winkles and waves are not generated. Hence the flatness of the window member 3 made of Be can be improved.
