    摘要: A ceramic dielectric composition is provided which consists essentially of bismuth titanate with substituents, expressed by the formula:Bi.sub.4-x Me.sub.x Ti.sub.3-y R.sub.y O.sub.12where R is at least one divalent metal selected from strontium, barium and lead, Me is at least one pentavalent metal selected from tantalum, niobium and antimony, and both x and y are numbers falling within the range of 0.4 to 2.0 and the ratio of x/y is within the range of 0.9 to 1.1. This composition may contain specified metal oxide additives. The ceremic dielectric composition is sintered at a relatively low temperature, and exhibits a dielectric constant having a reduced dependence upon temperature variations over a wide use range, a reduced dielectric loss, enhanced resistivity and breakdown voltage.

    摘要: A ceramic dielectric compositon is provided which consists essentially of a sintered metal oxide mixture expressed by the formula:[(Ba.sub.1.sub.-u Me.sub.u)O].sub.x.[(Ta.sub.1.sub.-v Nb.sub.v).sub.2 O.sub.5 ].sub.y.[Bi.sub.2 O.sub.3 ].sub.zwhere Me is at least one divalent metal selected from lead and strontium, and x, y, z, u and v are numbers falling within the following ranges0.05 .ltoreq. x .ltoreq. 0.80,0.05 .ltoreq. y .ltoreq. 0.30,0.10 .ltoreq. z .ltoreq. 0.80,0 .ltoreq. u .ltoreq. 1.00,0 .ltoreq. v .ltoreq. 1.00 andx + y + z = 1.0.This composition may contain specified metal oxide additives. The ceramic dielectric composition is sintered at a relatively low temperature and exhibits a dielectric constant varying linearly depending upon temperature variations over a wide use range, a reduced dielectric loss, enhanced resistivity and breakdown voltage, and therefore, is particularly suitable for "temperature-compensating" capacitors of a compact type with large capacity.

    摘要: A lead wire for a sensor has a conductor unit including at least stainless steel wires and copper wires. By setting the cross-sectional percentage of the stainless steel wires in the conductor unit within the range of 30 to 70%, it is possible to obtain a lead wire having low electrical resistance, and high flexibility, tensile strength and elasticity. There are preferred values in hardness and heat treatment of the stainless steel wires. The copper wires are preferably coated with an antioxidant film. The lead wire may include hybrid wires stranded together and obtained by integrally molding or forming stainless steel and copper. It is preferable that the lead wire is coated with an insulating coating material such as a Teflon type resin.

    摘要: There is provided a low-cost satellite broadcast tuner capable of receiving and processing both a QPSK modulation signal and an FM signal while assuring simple connection of an LNB (low noise block) to the tuner. A single front-end section including an RF stage, a mixer, a local oscillator circuit, an IF stage, an AGC loop is used for both an FM detector and an I/Q quadrature detector, so that both the FM signal and the QPSK modulation signal are received and processed in the single front-end section. In the above case, power supplied to the FM detector for detecting the FM signal, and power supplied to a local oscillator circuit required for detecting the QPSK modulation signal is turned off when receiving the FM signal.

    摘要: A remote control system includes a first remote control unit having complete functional capabilities and a second remote control unit having simplified and abbreviated functional capabilities. An apparatus is controlled in a detailed manner by the first remote control unit. For example, the operational mode and timer settings are set by the first remote control unit. On the other hand, the second remote control unit is limited to activating and deactivating the apparatus and/or the timer of the apparatus.
