    摘要: In a method of manufacturing a circuit board, a conductive paste is filled in a first hole formed on a first prepreg having both sides to which a first protective film is caused to stick so that a first circuit board is manufactured. A fiber piece housing paste obtained by mixing a fiber piece is recovered to obtain a recovery paste; filtration is carried out through a filter; a solvent or the like is added; and a viscosity, a composition ratio or the like is adjusted so that a reuse paste is fabricated. The reuse paste is filled in a second hole formed on a second prepreg having both sides to which a second protective film is caused to stick.

    摘要: A product and process of making such product in which a varistor is formed by diffusing lead borosilicate-type glass, into a surface of a fired or sintered zinc oxide substrate, i.e., "varistor element," during formation of an electrode on the surface of the substrate. Typically, an electrode paste or material, comprising a mixture or lead borosilicate-type glass frit and Ag powder, is applied to the substrate and provides the lead borosilicate-type glass for diffusing into the substrate. The improvement is that the lead borosilicate-type glass frit for the electrode paste or material comprises a mixture of PbO, B.sub.2 O.sub.3, SiO.sub.2 and at least one metal oxide selected from the group consisting of cobalt oxide, magnesium oxide, yttrium oxide, antimony oxide, manganese oxide, tellurium oxide, lanthanum oxide, cerium oxide, praseodium oxide, neodymium oxide, samarium oxide, europium oxide, gadolinium oxide, terbium oxide, dysprosium oxide, holmium oxide, erbium oxide, thulium oxide, ytterbium oxide and lutetium oxide.
