decoder which is selected instead of a decoder connected to a faulty memory cell; a link element inserted in series with the precharging transistor and connected between the power supply and the decoder output line; a signal generator which generates a non-selection signal for making the object decoder unselected only when a spare decoder is selected, the signal generator being provided in the spare decoder; and a transistor, having a gate to which the non-selection signal is input, with the drain and the source thereof being connected to the decoder output and ground, respectively, the transistor being provided in the decoder.
and to inhibit color shift. The invention includes electronic components encapsulated with poly(arylene sulfide) compositions containing zinc oxide.

A semiconductor device having a plurality of conductive leads extending therefrom is provided for reliably and repeatable positioning and holding a separate electronic device. The conductive leads are disposed apart to provide a predetermined space therebetween. Upstanding sidewall portions of desired dimensions are formed in the conductive leads at a predetermined distance from the central body portion of the semiconductor device. The separate electronic device is inserted in the space between opposite upstanding sidewall portions and is engaged and mechanically held thereby.
METHOD FOR LOCATING FAULTS IN A CARRIER SUBSCRIBER COMMUNICATION SYSTEM Tom Blackburn assigned to GTE Communication Systems Corporation Method and apparatus is disclosed for identifying faults in a subscriber carrier telephone system utilizing out-of-band pilot signals and comprising pluralities of cables and repeaters that are alternately connected in series between carrier equipment at a central office location and a subscriber station. Equipment at the office location transmits selected numbers of test pulses, having a test frequency that is between the transmitted and received channel and pilot frequencies, to the first cable. The pulses are detected at the first repeater and counted. A microprocessor is responsive to the test pulse count in the repeater for initiating associated tests on the cable and/or repeater, or for retransmitting test pulses on the next cable to the next repeater for causing it it perform designated tests. The results of the tests are sent to the office equipment in the form of reply pulses having a frequency that is below the lowest channel frequency.

4660127 FAlL-SAFE LEAD CONFIGURATION FOR POLAR SMD COMPONENTS Charles E Gunter assigned to North American Philips Corporation A fail-safe lead configuration for surface mountable chip-like polar electrical components wherein the lead of a first polarity is singulated and the lead of the second polarity is bifurcated, having the branches spaced a part such that a rotation of the device in its intended mounting location, thus reversing its polarity, or a displacement from its intended, position will result in an open circuit rather than a short circuit or other circuit failure.
