摘要： A device for pressing a capstan against a pinch roller in a magnetic tape recorder/reproducer perpendicularly elevates a supporting shaft of the pinch roller parallel with the capstan by a lever which converts the movement of a plunger to an elevational movement. Simultaneously the supporting shaft of the pinch roller is moved horizontally into parallel contact with the capstan by pressing the supporting shaft or bearing of the supporting shaft by movement of the same lever.

摘要： An audio signal mixer capable of performing a long mix editing with simple manipulations. A second audio signal producing means is prevented from producing a second audio signal when an operating member is positioned at a first end, while a first audio signal producing means is prevented from producing a first audio signal when the operating member is positioned at a second end. As the operating member is moved away from the first end or the second end, the first and second audio signals are mixed. As the operating member is moved toward the second end, the level of the first audio signal is gradually decreased while the level of the second audio signal is gradually increased. Conversely, as the operating member is moved toward the first end, the level of the second audio signal is gradually decreased while the level of the first audio signal is gradually increased. Thus, only by manipulating the operating member, it is possible to control two audio signal producing means such as CD players to reproduce or stop as well as to control a cross-fade operation for audio signals reproduced therefrom.

摘要： In order to avoid unnecessary use of telephone circuits, a recorded answering message advises a calling party to transmit a voice signal within a short time period after hearing a beep tone if the party wishes to have his message recorded. If the party here hangs up his telephone handset or otherwise does not transmit the required signal, the automatic answering apparatus is immediately returned to its standby state to await the next call, thereby freeing the telephone circuit. If the required signal is transmitted by the calling party, an incoming message recording tape is placed in a recording state for a predetermined time period in order to record the party''s message.

摘要： A logic circuit which detects the fact that an incoming message recorder tape in a telephone answering apparatus is full and causes the tape drive to be disabled. The circuit also detects abnormal conditions, such as breaking of the tape or under-speed rotation of either the tape supply or take-up reels. The circuit performs these functions without requiring any special processing or modification of the tape.

摘要： An improvement in an electro-acoustic converter having a magnetic anisotropic circuit with air gap therein, the improvement including an air gap formed of a magnetic material laminated with an insulating layer having a comparatively higher magnetic resistance in the magnetic circuit, thereby increasing a magnetic resistance against a magnetic flux caused by a voice coil and acting so as to reduce eddy current losses, and thus eliminating the reproduction distortion caused by the magnetic non-linearity of the magnetic circuit.
