摘要： A thermistor which includes a ceramic sintered body formed of a plurality of inner electrodes alternating with a corresponding plurality of ceramic layers, outer electrodes being connected to specific ones of the inner electrodes. Each ceramic layer a positive temperature coefficient of resistance. The inner electrode layers are obtained by injecting molten base metal having a low melting point such as lead, tin or lead-tin alloy into gap layers previously defined in the sintered body between the laminated ceramic layers from the outside under pressure and hardening the same.

摘要： A ceramic composition for use in production of non-linear resistors. This composition comprises strontium titanate (or a mixture containing strontium titanate as a major ingredient) and 0.1 to 1.0 mol % of Er.sub.2 O.sub.3, Ho.sub.2 O.sub.3 or mixtures thereof. In a preferred composition 0.02 to 0.2 mol % of at least one of MnO.sub.2, Co.sub.2 O.sub.3 or mixtures thereof are included. Non-linear resistors produced using the composition are comparable to those produced from conventional ceramic compositions in the threshold level voltage and non-linear factor but have greatly improved flexural strength.

摘要： A surface mounting type antenna system 10 is formed by spirally winding a conductor 14 made of copper or copper alloy, with a power supply member 12 provided at one end of the conductor 14, the other end thereof being a free end 13, on the edge faces of a rectangular parallelepiped as a dielectric substrate 11 by printing, deposition, pasting or plating. The dielectric substrate 11 is prepared by stacking a plurality of layers of ceramics, resin or a combination of ceramics and resin. On the underside 111 of the dielectric substrate 11 lies a power supply terminal 15 to which the power supply member 12 of the conductor 14 is connected. The power supply terminal 15 is simultaneously used as a fixing terminal for securing the surface mounting type antenna system 10 to, for example, a mounting board. Moreover, the conductor 14 squarely intersecting the axis C of the conductor winding is rectangular in transverse cross section having a width of w and a length of l.
