Title: Car body structure
Inventor: OOTOMO AKIHIRO
IPC: B62D25/08
Filed: 1993-08-06
Abstract: PURPOSE:To provide a car body structure that is able to check any bending deformation in the case where load has acted on a body panel joined together, yet better than ever before. CONSTITUTION:In the case where an impact load has acted by a car frontal crash, a tensile stress acts on two rising parts 3b and 3c of a patch 3, whereby the load is effectively shouldered. In addition, since a bulge 11b bulged beneath is formed as far as the specified length in a lower flange 11a, a compressive stress acts on this bulge 11b. Likewise, as this bulge 11b is not a plate form, when the compressive stress has acted, it is hard to be buckled so that this compressive stress is thus effectively bearable.

Abstract: PURPOSE:To increase the adhesive strength between two layers and to improve durability greatly by providing an adhesive layer on an elastic layer, mixing heat-conductive inorganic fillers with the elastic layer, and making the elastic layer higher in heat conductivity than the resin material of the adhesive layer. CONSTITUTION:A fixing roller 1 and a pressure roller 10 are of similar constitution, adhesive layers 5 and 15 are provided on elastic layers 4 and 14, and resin layers 6 and 16 are baked thereupon. Then the elastic layers 4 and 14 are formed of silicone rubber, and aluminum oxide, etc., is mixed inside as the heat-conductive fillers and deposited on the surface to make the heat conductivity of the elastic layers higher than the adhesives. Consequently, a sudden inflow of heat into the elastic layers 4 and 14 is reduced at the time of the baking to preclude heat deterioration, and the surface energy of the inorganic filler is large, so the adhesive strength between the adhesive layers and elastic layers becomes large, thereby improving the durability of the rolls greatly.
