  • Patent number: 6916873
    Abstract: A liquid thermosetting resin composition comprises (A) an epoxy resin, (B) a curing catalyst, and (C) a filler and is characterized by exhibiting a viscosity at 25° C. of not more than 1,500 dPa.s, a gel time of not less than 300 seconds at a temperature at which the composition exhibits a melt viscosity of not more than 10 dPa.s, and a gel time at 130° C. of not more than 600 seconds. In the production of a printed wiring board by superposing an interlaminar resin insulating layer and a conductive circuit on the surface of the wiring board having a conductive circuit pattern including hole parts, a hole filling process is performed by filling the hole parts mentioned above with the composition mentioned above, effecting precure of the composition by heating, then polishing and removing parts of the precured composition protruding from a surface defining the hole parts, and further heating the precured composition till final curing.

  • Patent number: 6609745
    Abstract: A seat device of a vehicle including a substantially flat floor surface substantially extending across a full cabin space of the vehicle, front row seats, center row seats and a rear row seat disposed in a longitudinal direction of the vehicle on the floor surface, a seat storage pan extending rearward the rear row seat and downward a level of the floor surface, the front row seats being disposed with a space, the center row seats including a plurality of seats in which at least one of the seats is movable in a lateral direction of the vehicle. When the rear row seat is received in the seat storage pan, a substantially flat and continuous surface of a substantially same level as the floor surface is formed rearward the center row seats to a rear end of the cabin space with a substantially full width of the cabin space.

  • Patent number: 5325585
    Abstract: The front portion of a roof panel has left-hand and right-hand roof opening sections, each roof opening section being wide open without a roof side rail on its transversely outer side. A movable roof member is mounted on the roof opening sections so as to be movable longitudinally through a base frame fixed to the body of a vehicle, thereby opening the roof opening sections when the movable roof member is moved in its rear position and closing it when it is moved in its front position. The base frame contains a front section to be mounted to a front header of the body, a rear section to be mounted to a front edge portion of a rear roof panel section, a middle section for connecting middle portions of the front section and the rear section, and a guide section extending rearward from a transversely outer side portion of the rear section.
