摘要： A proximity detector includes a magnet having steel or iron pole piece plates mounted at front and rear pole ends of the magnet, and a silicon integrated circuit mounted to the outer surface of the front pole piece centered about at the magnet pole axis. The integrated circuit includes two essentially identical Hall elements having outputs connected series opposing, i.e. differentially rather than aiding, so that distortion of the magnet field ambient to the integrated circuit caused by a ferromagnetic article passing by results in a gradient field between the Hall elements producing a differential output signal. The dual Hall element integrated circuit leads to a low differential composite offset voltage while the front pole piece renders the magnetic flux density much more uniform further reducing this dual-Hall-element composite offset voltage.

摘要： A metal electroding powder for use in making monolithic ceramic capacitors comprises a silver-palladium alloy powder having a composition, by weight, of 90Ag/10Pd and having palladium oxide on the surface of the alloy particles. The powder is made by heating a silver-palladium alloy powder containing less than 90% by weight of silver, in air at about 500°C so as to oxidise a portion of the palladium to form palladium oxide at the surface of the alloy particles and to increase the silver content of the alloy until it has a composition, by weight, of 90Ag/10Pd.

摘要： Two wound-metallized-polypropylene capacitor sections (10, 26) of cylindrical dimensions are housed in an oval metal can (56). One capacitor section (26) forms a single capacitor of two metal film electrodes (12, 14). One metal film electrode (14) of the other capacitor section (10) is opened or interrupted in the winding. The uninterrupted other film electrode (12) of this other section is terminated at the bottom end (36) while the two interrupted inner and outer winding films (14a, 14b) are separately terminated at the top end (32, 34). The bottoms (30, 36) of both capacitor sections (10, 26) are connected together and to a feed-through terminal (50). Said outer film (14b) is connected via a conductive strap (38) to the top termination (28) of the one section (26) and to a second terminal (52), while the inner film (14a) is connected only to a third terminal (48). In this way, an optimally dense oval package provides two capacitors at the package terminals that may have a ratio of values ranging from 3 to 12, ideally suited for use in air conditioners.

摘要： A distributed parameter delay-line comprises two essentially identical distributed parameter delay line sections (10, 20) having series connected solenoidal coils (14, 24) and mutually parallel axes (11a, 21a). The winding directions of the two coils (14, 24) are such that there is a winding direction reversal in going from one section to the other. A low frequency uniform unidirectional magnetic field having a component parallel to the section axes will induce voltages in the two coils that are of opposite polarity and no net induced voltage will appear between the free ends of the series connected coils. The delay line sections may be disposed either side-by-side (figure 1) or coaxially (figure 3). In order to suppress high frequency magnetic field interference, a copper or aluminium shield (50) can be provided ; around the two sections (figure 5).

摘要： An integrated circuit field-to-electrical energy sensor is capable of being energized through two DC voltage supply terminals (18, 20). Each of a plurality of such sensors, when connected in parallel so as to be energized from a single DC supply voltage source, is capable of recognizing by means of an address code comparator (28) a unique pulse signal code superimposed on the DC supply voltage (VCC). Stimulated by that code which is unique only to that sensor, that sensor powers up a transducer (38), e.g. Hall element, and responds by drawing a particular current pattern from the common DC voltage source indicative of the presence (or absence) of a field, e.g. magnetic, that is ambient to that sensor. Electrically controlled energy to the transducer (38) provided only when the unique code is present is supplied by the switchable of two regulated voltage outputs from a dual voltage regulator (36) having a control input connected to the output of the address code comparator (28). The steady (unswitched) regulated output voltage supplies energy to the MOS logic including the address code comparator. The sensor quiescent current drawn from the DC voltage supply line is thereby caused to be very low value which becomes increasingly advantageous as more and more sensors are operated in parallel on the same DC supply line.
