摘要:
A method for manufacturing a magnetic recording medium of the present invention includes a magnetic layer forming step in which a drying process is performed. The drying process includes: a pre-heating stage in which a magnetic coating film is heated until the surface temperature of the magnetic coating film stops rising and reaches a substantially constant temperature; a constant rate drying stage that is performed after the pre-heating stage in which the surface temperature of the magnetic coating film is held substantially constant; and a falling rate drying stage that is performed after the constant rate drying stage in which the surface temperature of the magnetic coating film is increased to be higher than the surface temperature during the constant rate drying stage to harden the magnetic coating film. The constant rate drying period in which the constant rate drying stage is performed is 0.2 seconds or more. The first solvent is made of one solvent or two or more solvents having different boiling points, and the difference (Tb−Ts) between the boiling point Tb of the solvent having the lowest boiling point among the solvents contained in the first solvent and the surface temperature Ts of the magnetic coating film during the constant rate drying period is 1 to 50° C.

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.

摘要:
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.

A method for the production of a sunroof includes a step for applying adhesive into an edge section and a molding groove along the edge section of glass disposed accurately on a lower mold. A foaming material is applied in the molding groove at a peripheral portion of the glass outside the applied adhesive. The adhesive and the foaming material applied on the glass are molded by connecting the lower mold to an upper mold with a frame, and then heated a step of heating in a state in which the molds are pressed in a vertical direction. The lower and upper molds are detached, and a sunroof is discharged as a finished product.
