Abstract: A bonded structure of an Al alloy pressed plate, in which another member is bonded onto the surface of the Al alloy pressed plate that has a lubricant layer by use of an epoxy resin based adhesive. The adhesive contains an epoxy resin, a dehydrated phosphate and a latent curing agent. The epoxy resin comprises a polyester type epoxy resin and at least one resin selected from the group consisting of a bisphenol epoxy resin, a rubber-modified bisphenol epoxy resin, and a urethane-modified epoxy resin.

Abstract: A vehicle body panel having a honeycomb sandwich structure in which a honeycomb core is sandwiched between a first and a second plate includes a subhoneycomb panel formed by adhering the first plate to one major surface of the honeycomb core beforehand. The subhoneycomb panel is pressed against the second plate which is constituted by a part of a structural panel of a vehicle body with the intermediary of an adhesive layer, the other major surface of the honeycomb core being adhered to the second plate. The connection of the subhoneycomb panel to the second plate is performed after the structural panel has been connected to a strength member of the vehicle body, e. g. after a washing stage. Such a vehicle body panel with a honeycomb sandwich structure is achievable without resorting to any substantial modification of an existing vehicle body assembly line.

Abstract: A bath additive composition comprises an aluminum salt and a carbonate and makes the pH of bath water 8 or higher but less than 9 when the bath additive composition is dissolved in the bath water. The bath additive composition does not damage bathtubs, bath water heating devices, or the skin of users, provides a refreshing feel to the skin after bathing, and has an excellent ability of suppressing perspiration.

Abstract: A resinforced cover member for automobile made of a synthetic resin comprising a lid body having a generally rectangular shape and a plurality of ribs extending generally perpendicularly from a bottom face of the lid body. The ribs include various types of ribs. A first set of at least two peripheral ribs extend along one longer side of the lid body while a second set of at least two peripheral ribs extend along the other longer side. A third pair and a fourth pair of peripheral ribs extend along the shorter sides of the lid body. A first set of angular ribs continuously extend to connect a generally central point of the one longer side of the lid body and the two end portions of the other longer side. A second set of angular ribs continuously extend to connect a generally central point of the other longer side and the two end portions of the one longer side. Additional angular ribs can be arranged parallel to the first and second set of angular ribs.
