摘要： PURPOSE:To improve reliability of a solder connection by disposing a platelike spacer between an integrated circuit board and a printed board, obtaining the thickness of the solder by thermal expansion, thermal deformation, and obtaining an air gap between the circuit board and the spacer. CONSTITUTION:A platelike spacer 4 made of metal or synthetic resin is disposed between an integrated circuit board 1 made of ceramics placed with an integrated circuit and a printed board 2 made of glass epoxy resin, etc., and the terminal 1a of the board 1 is connected to the land 2a of the board 2 by solder 3 such as pastelike solder, etc. Thereafter, the board 2 is heated to melt the solder 3, thereby completing solder connection. In this case, the spacer 4 is so set as to obtain a predetermined solder thickness to obtain reliability of the solder connection. When the board 2 is heated to melt the solder 3, the spacer 4 is similarly heated, the board 1 is raised by thermal expansion or thermal expansion, the spacer is largely thermally shrinked by cooling or recovered, and hence an air gap 8 is generated between the board 1 and the spacer 4. As the spacer, a bimetal or a shape memory material may be used.

摘要： PURPOSE: To improve the efficiency of optical coupling between an optical fiber and light emitting and receiving elements by coupling the light emitting and receiving elements which are connected to an electric circuit with the optical fiber by a fiber plate and sealing them airtightly in one body.
CONSTITUTION: The electric circuit 1 is coupled electrically with the fiber plate 7 to which the light emitting and receiving elements 5 and 6 are fitted. The optical fiber 8 is coupled having its tip part brought into contact with the fiber plate 7. The electric circuit 1, light emitting and receiving elements 5 and 6, fiber plate 7, and optical fiber 8 are sealed airtightly by a case 10, a rubber cover 11, etc., to form an integrated connector. In this constitution, the distance between the light emitting element 5 and optical fiber 8 is short, so fiber light input increases. Therefore, the light emitting element 5 and optical fiber 8 are coupled together closely through only the fiber plate 7 where light can travels straight, so the efficiency of optical coupling is improved. Further, all the principal parts are sealed airtightly, so field assembly becomes possible.

摘要： PURPOSE:To reduce size and cost and facilitate assembly and to allow terminal equipment to diagnose itself by providing an optical waveguide body to a substrate provided between opposite optical paths and also providing a photodetecting element and a light emitting element on both surfaces, and moving up and down the substrate. CONSTITUTION:The waveguide body 16 is inserted into round holes of plural substrates 15 which are already wired and then fused and fixed; and the photodetecting element 8 is adhered in a rectangular hole 15b and the light emitting element 9 is adhered in the rectangular hole 15c in the other surface. A switch box 21 is fitted to the substrate 15 and a light signal is sent to the optical fiber 2 on the right side through the conductor 16, but a light signal emitted by the light emitting element 9 returns to the photodetecting element 8 through an optical restoring fiber circuit 28 in the test mode of the terminal equipment, which diagnoses itself. The substrate 15 is attracted upward through the operation of a magnet 26, the element 8 is irradiated with the light signal to input information to the terminal equipment, and unnecessary information is returned to the original loop circuit by the element 9. Therefore, connection parts are decreased and the small-sized, inexpensive constitution allows the terminal equipment to diagnose itself.

摘要： PURPOSE: To improve the fiber coupling efficiency by optical transmission line insertion by providing plural optical transmission lines whose incidence angle and projection angle are equal to each other, and arranging the optical lines in parallel to an optical axis.
CONSTITUTION: A spot light source 1 having light intensity P is provided and optical lines 3 and 4 incident on an optical path 2 at angles θ
1 and θ
2 propagate in the optical transmission line 2 in the thickness direction while reflected totally by the internal reflecting plate 9. Projection line from the optical transmission line 2 is split into light beams 5 and 5', and 6 and 6' having projection angles ±θ
1 and θ
2 , and they have equally divided light intensity. This optical system is equivalent to a system in which two spot light sources 7 and 8 having light intensity P/2 are positioned ±l
1 away from the projection surface of an optical path. Therefore, when outputs of the light sources are coupled with a fiber through the optical transmission line, the distance betwen the light source and the fiber is shortened equivalently and the fiber coupling efficiency is improved.

摘要： PURPOSE:To eliminate the need for the molding of the signal terminals of a light-emitting device and a photo-detector, and to decrease man-hours while reducing a mounting area and miniaturize an optical transmission module by cutting the signal terminals in short size and using a flexible printed wiring board for connecting the signal terminals and a substrate. CONSTITUTION:A transmission circuit 7 and a reception circuit 6 are mounted to a substrate 5, and the signal terminals of a light-emitting device and a photo- detector are connected to the substrate 5 by flexible printed wiring boards 1, 2. The flexible printed wiring boards 1, 2 can be prepared in conformity with the shapes of the signal terminals and the pattern of the substrate 5, the signal terminals of the light-emitting device and the photo-detector need not be molded, and the signal terminals can easily be connected. Since an optical transmission module has excellent flexibility, the stress of connecting sections generated by the difference of the thermal expansion coefficients of the light- emitting device and the photo-detector fixed to a case and the substrate 5 can be absorbed, and reliability is also improved. Since curvature can be reduced, a mounting area can also be diminished.
