  • Patent number: 8202457
    Abstract: A tensile stress is applied to solidified resin. The tensile stress is so small that the solidified resin formed in the sprue by solidification of molding material does not break and is so large that the solidified resin formed in the sprue is separated from the inner surface of the sprue due to a reduction in the diameter of the cross sectional area thereof. For the application of such a tensile stress, the runner stripper plate holding the solidified resin is moved away from the nozzle and sprue bushing. This state is maintained for a predetermined time to separate the solidified resin from the inner surface of the sprue.
    Type: Grant

  • Patent number: 5212121
    Abstract: This invention is concerned with ceramic substrates for multilayer interconnection. This invention is also concerned with a raw batch for ceramic substrates which require a calcining temperature as low as 1,000.degree. C. or lower upon their production, are low in dielectric constant and have a coefficient of thermal expansion close to that of silicon and also with a process for the production of the substrates. This invention makes use of a raw batch which permits the use of a low resistance conductor such as Ag-Pd, Ag, Au or Cu and also the production of substrates by low-temperature calcination. The raw batch contains borosilicate silicate glass powder, and aluminum borate powder and at a weight ratio of 40-80 percent to 20-60 percent. The raw batch can additionally contain one or more specific oxides in particular proportions.
