    摘要: An electret transducer is comprised of a motor and signal processing apparatus, that may include an amplifier and/or impedance matching means, disposed within a sealed conductive housing. The motor is fabricated in place within a housing and the signal processing means is mounted on the underside of the cover for the housing so that each may be independently tested prior to combining into a unitary structure. The motor is comprised of easily fabricated and assembled components that include means for spacing a backplate from the walls of the conductive housing and a spacer intermediate the backplate and the center of a diaphragm. The backplate and the diaphragm are provided with registering apertures. The amplifier is mounted to the cover to conductively connect to the housing and to provide rigid outwardly extending terminals for ready connection to further electrical circuits, as in a hearing aid. The component parts of the transducer are fabricated by half etching through the use of etching resist patterns that are placed in registering cooperative disposition on the surfaces of a flat sheet of material of which the components are comprised, to provide variations in thickness of predetermined portions of the finished components.

    摘要: To reduce fading in a diversity receiver, the signals received on two spaced-apart antennas are added together without phase shift while amplitude of the sum is above a certain threshold. When the signal falls below the threshold, the signal from a squelch detector causes the sum amplitude to be stored and then a 180.degree. time delay to be inserted between one of the antennas and the adding circuit, after which time, the new sum amplitude is compared with the stored signal amplitude. If the new signal has increased or remained the same, the 180.degree. phase shift remains in place but, if it has deteriorated, it is removed and the circuit reset.

    摘要: A magnetic tape player-changer for sequentially playing endless, multi-track magnetic tapes housed in cartridges. The player-changer includes a magazine housing a plurality of cartridges, and a track along which the magazine is moved to sequentially position cartridges in a playing position. The magazine is provided with a surface having a plurality of intersecting, curved grooves, and the player-changer is provided with a driven, revolvable cam which rides in the grooves. The cam and grooves are so oriented as to smoothly advance the magazine to position sequential cartridges in the playing position with little noise. The player-changer includes transducer stepping and step-counting means for advancing a transducer from one pair of tracks to another of a tape and for counting the steps so as to advance a new cartridge into the playing position when all of the tracks of the previous tape have been played. Means are also provided to reverse the travel of the magazine to its original position when all of the tape cartridges have been played. The principles of our invention are also applicable to rotary magazines for continuously, sequentially indexing magnetic tape cartridges to a playing position.

    摘要: A vertically symmetrical tape guide for use on a base of a tape deck of audio-visual equipment. A locating pin on one of three triangularly spaced support members of the tape guide locates and aligns the tape guide in a hole in the base of the tape deck. A screw affixes the tape guide to the base of the tape deck. A contoured arm supports two horizontally extending fingers vertically spaced apart by the width of the tape to provide a guide for the tape when traveling across a tape head mounted to the base of the tape deck. The vertically symmetrical tape guide is configured so that the tape guide can be reciprocally mounted on either side of and adjacent to the tape head.
