A multi-metal layer wiring TAB tape carrier capable of forming a fine pattern without affecting the thicknesses of conductive metal layers, and a process for fabricating the multi-metal layer wiring TAB tape carrier. This TAB tape carrier is constructed such that respective dielectric film layers are interposed between adjacent ones of plurality of conductive metal layers having a predetermined wiring pattern, such that the dielectric film layer is formed with interfacial connection holes, and such that a conductive via layer is formed in the interfacial connection holes to electrically connect adjacent conductive metal layers. The conductive via layer is formed by a vapor deposition method such as evaporation, ion plating or sputtering. Alternatively, a portion of the conductive metal layers and the conductive via layer are simultaneously formed. Especially according to the latter method of forming a portion of the conductive metal layers and the conductive via layer simultaneously, the conductive via layer need not be formed after the conductive metal layers so that the fabrication steps are simplified. Moreover, the thicknesses of the conductive metal layers are not adversely affected later, and the conductive metal layers and the conductive via layer can be positioned highly precisely to form a fine wiring pattern.
摘要:
An epoxy resin composition which comprises an epoxy resin derived from an ester of an alkadienealcohol; an epoxy resin prepared by reacting an epichlorohydrin and a bisphenol and an acid anhydride curing agent. The cured product has very high mechanical strength and cracking resistance and is useful as an electrical insulating material.

A weaving method for woven goods in which the warp yarns are disposed among reed dents of uniform spacing in a reed according to a sequence of numerical values having a 1/f fluctuation, thereby imparting a 1/f fluctuation to the arrangement of warp yarns.
摘要:
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.
摘要:
A weaving method and reed where the method is practiced with the reed having spacings between dents of 1/f fluctuations resulting in a woven fabric which has a warp density of 1/f fluctuations. The spacings are established by winding yarn having a 1/f fluctuation around the dent support bars with the dents positioned between the coils of wrapped yarn.
摘要:
An outer lead of a metal lead frame is connected to an inner lead of a flexible lead-patterned substrate via a Au-Sn alloy layer. The Au-Sn alloy layer contains Au of 10 to 40 weight %.An inner lead of a metal lead frame is connected to a patterned lead of a flexible lead-patterned substrate by a heating tool. The inner lead is coated on bottom and side surfaces of its tip portion. The bottom surface faces the patterned lead.

A home hair-setter whose body is a cylindrical heat-resistant elastic member and wherein the outer peripheral surface of the body of the hair-setter is used to curl hair; the hair-curling section of the body is enclosed in a cylindrical envelope; and the body of the hair-setter has at least one of its both ends left open.
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.
