  • Patent number: 6719872
    Abstract: A hot melt composition containing, as essential ingredients, a specific high-molecular weight styrene block copolymer, a specific polyphenylene ether resin and a viscosity adjuster. The hot melt composition permits an easy assembling and sealing between a plurality of members. More particularly, it is possible for the hot melt composition to be melted and applied to one member in advance of the assembling work, such that the one member with the hot melt composition already applied thereto can be carried into a work site or a work line and simply joined to another member at those places. Further advantageously, the members joined or assembled via the hot melt composition can be disassembled without difficulty, which enables recycling of the used members.

  • Patent number: 6654515
    Abstract: A photoelectric back plane board is provided to facilitate the relative positioning of an optical data bus and light emitting/receiving devices, interconnection of a circuit board for optical communication and respective elements, and supplying power and inputting/outputting signals to/from the printed circuit board. In the photoelectric back plane board, the optical data bus is inserted into a recess within an optical data bus fixing board and a connector holding light emitting/receiving devices is positioningly fixed to the fixing board via through holes H formed in the fixing board so that relative positioning of the signal light incoming/outgoing areas and the light emitting/receiving devices can be easily achieved. By mounting the fixing board on a printed circuit board on which an electrical connector is provided, interconnection of a circuit board mounted on the optical connector and the printed circuit board is achieved by means of the electrical connector.

  • Patent number: 6621950
    Abstract: An optical data bus fixing board suitable for using an optical data bus as a signal transmission medium and an optical back plane board. A recess for inserting an optical data bus, which is made of a rectangular light transmissive resin substrate and comprises a step-wise side along the longitudinal direction and signal light incoming/outgoing areas formed by sloping the longitudinal end of each step at 45 degrees in relation to the substrate surface, is formed in the surface of a flat plate in order to easily and efficiently use the optical data bus as a signal transmission medium for interconnecting various signal processing circuits. The optical data bus is inserted and fixed within the recess by being pressed and biased from the back end by a first holding member including a reflective diffusion plate and from the side by a second holding member including a flat spring.
