Abstract: Conductor track structures arranged on a nonconductive support material, especially fine conductor track structures, composed of a heavy-metal base and a metallization layer applied to the base, and a method for producing the conductor track structures. The heavy-metal base contains heavy metal nuclei which are formed by breaking down a nonconductive heavy metal complex by using UV radiation produced by an excimer laser. The heavy metal complex is applied to the entire microporous surface of the support material and covers the surface of the support material in the area of the conductor track structures. Conductor track structures produced according to the invention are comparatively easier to produce than previously known conductor track structures and exhibit very good adhesion.

Abstract: In laminates prepared by laminating a base material and sandwich base material via a bonding layer, the adhesion strength between the sandwich base material and bonding layer is not less than 200 g/15 mm wide at 23 ° C. and the bonding layer is formed of a resin composition which comprises an ethylene/ &agr;-olefin copolymer resin, thus to provide useful laminates which are very excellent in adhesion properties to metal foil, deposited metal surfaces of metal-deposited films, and surfaces of other sandwich base materials and in tear properties such as unsealing properties, and have low smell and high strength as packaging films.
Abstract: A Ni plating layer 3, a Cu plating layer 11, a Zn—Ni alloy plating layer 4 and a chromate layer 5 are formed sequentially in that order on the outer surface of a steel base 2. The Cu plating layer 11 interposed between the Ni plating layer and the Zn—Ni plating layer seals up pinholes in the Ni plating layer and enhances the sacrificial corroding action of the Zn—Ni alloy plating layer.
Abstract: This invention can considerably improve the adhesion property of a film to a matrix surface of a silicon steel sheet by forming an interface layer such as nitride-oxide layer of one or more selected from Fe, Si, Al and B or an extremely thin base film formed by finely dispersing nitride-oxide of one or more selected from Fe, Si, Al and B in the same film components as a tension insulating film at an interface between the matrix surface and the tension insulating film, or further by immersing in an aqueous solution of a chloride mainly composed of SiCl4 to dissolve the matrix surface or conducting a smoothening treatment or a pickling treatment with an aqueous solution containing SiCl4 prior to the formation of the interface layer, and hence ultra-low core loss grain oriented silicon steel sheets having a core loss considerably superior to that of the conventional one and an excellent magnetostriction property can be obtained very cheaply and in a higher productivity.
Abstract: Boric acid is used as a surface-protection coating for protecting a desired surface area of a glass article from weathering, contamination by dirt, dust, moisture and others, and streaks and/or cracks due to collision and friction with other objects. The boric acid coating is readily washed out by water upon actual use of the glass article.
Abstract: A tip cap hole is loaded with a first composition comprising particles of a first alloy having a solidus temperature above the brazing temperature. The first composition is covered with a second composition comprising particles of a second alloy having a liquidus temperature below the brazing temperature. The second composition is heated to the brazing temperature to cause particles of the second alloy to melt to form a liquid of the second alloy which is carried into spaces between the particles of the first alloy by capillarity. The liquid of the second alloy is cooled to form a solid securely bonding the particles of the first alloy. By weight, the second alloy has no more than 1% B and from 3% to 11% Si. The first alloy has Cr and at least about 5% Al, at least about 0.5% Hf, no more than 0.5% Ti.
