摘要:
The present invention relates to a bonded assembly characterized in that a board having a convexed portion on a jointing surface thereof and a board having, on a jointing surface thereof, a concaved portion or a through hole to be engaged with the convexed portion are jointed with adhesives. Also, the present invention relates to a bonded assembly characterized in that an adhesive is coated on the portion other than the convexed portion of the board so that the coating thickness is smaller than the height of the convexed portion, and then the board is jointed to another board having a concaved portion or a through hole, after making alignment of the boards. Further, the present invention relates to a rivet having means for fitting to and temporarily fixing to an inserting through hole, and a method of jointing boards which comprises a step for inserting, fitting and temporarily fixing the rivet having the means for temporarily fixing to the inserting through hole on the board. The present invention can provide a highly reliable bonded assembly, a method of jointing boards therefor and a rivet for facilitating jointing the boards, which assure easy and accurate alignment of the boards, secure an adhesive coating thickness required, prevent the adhesive from adhering to unnecessary portions and increase the strength as the bonded assembly.

Continuous fluorination of carbon is carried out by employing an apparatus for contact reaction of solid powder and reactive gas which comprises a horizontal reactor having a trough provided with weirs (e.g. height: 1 to 6 mm., interval: 5 to 30 cm.) and a vibrating means for vibrating the trough, and in which carbon particles supplied continuously are transported on the trough in a form of thin layer by the vibration of the trough while continuing the reaction by contacting efficiently the carbon particles with a fluorine gas. The contact reaction is efficiently conducted without accumulating the reaction heat to produce the fluorinated carbon in high yields, and the process is useful for the mass production. The apparatus is also useful for various contact reaction of a solid powder and a reactive gas.

A weaving method that imparts a 1/f fluctuation to the weave pattern. Adjacent and different numbered groups of different yarns, for example black yarn and white yarns, are alternately arranged in contiguous reed dents. The sequential number which is associated with each group manifests a series of numbers which effect the 1/f fluctuation. Following separation of the warp yarns into two sets by raising and lowering of healds to form a shed and passage of weft yarns therethrough, a woven fabric with a stripped 1/f fluctuation in the warp direction is created.

A weaving method that imparts a correlation of a 1/f fluctuation to the texture pattern of a woven fabric by passing warp yarns through a plural number of healds in a specific numerical sequence. The healds are then manipulated to separate the warp yarns into two sets to form a shed therebetween through which a weft yarn is inserted. For one texture pattern, warp yarns are threaded in groups in numbers corresponding to the values of a numerical sequence with a 1/f fluctuation through one set of healds. For another texture pattern, warp yarns are threaded in groups through another set of healds so as to alternate with the first groups, thereby weaving a plural number of texture patterns into the woven goods, with the overall texture design having a 1/f fluctuation.

A molding material having low moisture permeability for use in the stators of submersible motors. The molding material comprises approximately 20-30 parts by weight of an epoxy resin, approximately 1-3 parts by weight of a curing agent, approximately 0.5-1.5 parts by weight of zinc stearate, approximately 2-3 parts by weight of a mechanical reinforcing agent, approximately 7.5-56.5 parts by weight of quartz powder, and one or more substances selected from anhydrous gypsum and silica gel, with the total amount of said inorganic substance(s) being approximately 55-20 parts by weight, and with the total amount of quartz powder and said inorganic substance(s) being approximately 62.5-76.5 parts by weight. Because of its low moisture permeability, the insulating properties of the molding material can be maintained indefinitely.
