    摘要： Lens surfaces are transferred by press-molding a glass material (16) by an upper mold (1) and a lower mold (2). After the lens surfaces are transferred, the outer circumferential portions of the upper and lower molds (1, 2) are clamped and pressed sideways to correct a shift between the optical axes of the transfer molding surfaces of the upper and lower molds (1, 2) and an inclination of the optical axes.

    摘要： Non-magnetic ferrite composition used in the composite multilayer part of the invention is based on ferrite containing Fe.sub.2 O.sub.3 and CuO and/or ZnO and further contains 1 to 30% by weight of four oxide components of MgO, BaO, SiO.sub.2, and B.sub.2 O.sub.3 or five or six oxide components including the four oxide components plus at least one of SnO.sub.2 and CaO. Since the use of this non-magnetic ferrite minimizes the difference in coefficient of linear expansion between different materials used, the non-magnetic ferrite, when applied to composite multilayer parts such as shielded multilayer chip inductors, shielded multilayer transformers, and multilayer LC composite parts, prevents occurrence of cracks in the interior and avoids a lowering of circuit resistance due to precipitation of CuO, ZnO or the like at the interface between different materials. There result composite multilayer parts with improved characteristics.

    摘要： A multilayer ceramic chip capacitor includes alternately stacked dielectric layers and internal electrode layers. The dielectric layers contain barium titanate as a major component and magnesium oxide, manganese oxide, barium oxide and/or calcium oxide, silicon oxide and optionally, yttrium oxide as minor components in such a proportion that there are present 0.1-3 mol of MgO, 0.05-1.0 mol of MnO, 2-12 mol of BaO+CaO, 2-12 mol of SiO.sub.2 and up to 1 mol of Y.sub.2 O.sub.3 per 100 mol of BaTiO.sub.3. The capacitor satisfies the standard temperature dependence of capacitance and shows a minimized change of capacitance with time under an applied DC electric field and a long insulation resistance life. Where the dielectric layers contain 0.1-3 mol of MgO, 1-5 mol of Y.sub.2 O.sub.3, 2-12 mol of BaO+CaO, and 2-12 mol of SiO.sub.2 per 100 mol of BaTiO.sub.3, the capacitor shows improved DC bias performance.
