摘要:
A reduction reoxidation ceramic semiconductor having a central ceramic portion with a dielectric layer formed thereon by oxidation. The ohmic electrode is formed from a material (e.g. an aluminum-glass frit) that prevents formation of the dielectric layer under the ohmic electrode during reoxidation. The non-ohmic electrode is formed on the dielectric layer.

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.

A conductive paste is provided, which has good conductivity and good adhesiveness to substrates and has good long-lasting stability of these properties, and which, when applied to a through-hole of a multi-layered substrate, ensures improved reliability of bonding to the end faces of conductive layers in the through-hole. Therefore, the paste does not require through-hole plating. The conductive paste comprises (A) 100 parts by weight of a resin component that contains an acrylate resin and an epoxy resin, (B) from 200 to 1800 parts by weight of a metal powder of at least two metals that contain at least one low-melting-point metal having a melting point of not higher than 180° C. and at least one high-melting-point metal having a melting point of not lower than 800° C., (C) from 0.5 to 40 parts by weight of a curing agent that contains from 0.3 to 35 parts by weight of a phenol-type curing agent, and (D) from 0.3 to 80 parts by weight of a flux.
摘要:
A digital audio tape recorder and a method for operating the same, especially in a music program jump selecting mode. In one embodiment, the state of an erasure-preventing tab is detected, and TOC (Table-Of-Contents) information is transferred from the tape to a TOC information memory only when the erasure-preventing tab is set to an indicate an unrecordable state. In accordance with another embodiment, when the music program number of the music selection presently being reproduced is known and the program number is aligned, a target music program number is calculated and displayed.
