Abstract: A system (20) for controlling deceleration of a motor (22) during an abrupt power-off condition includes a processor (40), a motor control circuit (50), and a secondary power source (70). During normal power-on operation and based on currently prevailing operation parameters, processor (40) routinely generates a contingent motor-governing deceleration signal for potential use in governing motor (22) should the power-off condition occur. In response to the occurrence of a power-off condition, motor control circuit (50) controls motor (22) in accordance with the contingent motor-governing deceleration signal to achieve orderly deceleration. Secondary power supply circuit (70) provides power to motor control circuit (50) during the power-off condition.

Abstract: A method and apparatus is disclosed for eliminating the effect of unevenly wound magnetic tape media on the guidance of the media relative to a tape transport read/write head. A first guide is used to axially twist the tape or other media 90 degrees relative to the longitudinal axis of the media being unwound from a tape spool. Another guide is then used to twist the media into to an alignment which is co-planar with a surface of the tape transport read/write head. This procedure eliminates the effect of staggerwrap from the tape spool and allows the spooled media to be more precisely aligned with respect to a desired media path of travel.

Abstract: The communications monitor and logger preferably uses reel-to-reel tape recorders to continuously record communications over multiple channels such as multiple telephone lines. Each tape recorder uses a pair of capstans and pinch rollers to move the tape during recording and play-back. The pinch rollers are engaged with the capstans by means of a solenoid through a linkage and spring coupling. The spring is stretched by the solenoid only after the pinch roller makes contact with the capstan, thus reducing the force required from the solenoid. The spring is pre-loaded so as to improve the accuracy with which the force applied to the pinch roller is determined. The solenoid is used to apply force to the spring only when the solenoid plunger approaches its seat, so as to make the most efficient use of the solenoid and minimize its size and electrical power usage.

Abstract: A function, such as ejection of a cassette from a magnetic-tape-cassette apparatus, is performed by depressing two pushbuttons simultaneously, where each of said pushbuttons moves an associated button rod when depressed singly to perform an individual apparatus function, such as fast winding. A third rod such as an ejection rod is moved when the two buttons are depressed simultaneously, via a control member arranged on the third rod by a support. The control member is engaged by a respective guide surface to be displaced laterally when one of the buttons is depressed, and remains in a central position when both buttons are simultaneously depressed, to move the third rod in the direction of buttom movement. When only one button is depressed, during return movement of the button to the initial position a spring biases the control member to its central position, so that the entire mechanism occupies minimal space and is easily redesigned into a three button actuating mechanism.

Abstract: A mechanism for moving a magnetic read/write recording head across a tape storage medium. A linear actuator drives an output shaft which carries a cable connector. A flexible cable is connected with the cable connector at one end and at the other end with an elevator bracket which carries the recording head. The cable is bent through a 90.degree. bend between its ends along an arcuate guide surface. The elevator bracket moves up and down across the tape on guide pins. A spring maintains the cable under tension to translate horizontal extension and retraction of the actuator shaft into corresponding vertical movement of the tape head. The use of a cable reduces the application of moments to the head and avoids applying rotational forces.

Abstract: As tape moves through a closed loop, high-speed tape transporter (10) loops of the tape are accumulated and stored in a tape bin (64). The capacity of the tape bin (64) is increased by extracting air from and lowering the air pressure in the region of the bin (64) occupied by the loops of accumulated tape and inside the loops of tape sufficient to cause the accumulated tape to compress into tighter loops which occupy less space in the tape bin (64). Air extraction takes place through a vacuum port (95) which communicates with the interior of the tape bin (64) and which is connected to a vacuum supply (11A).

Abstract: First and second operating members can reciprocate in parallel to each other. When the first operating member moves one reel shaft rotates at high speed in the tape-winding direction. When the second operating member moves the other reel shaft rotates at high speed in the tape-winding direction. A tape-direction-changing piece can reciprocate in parallel to the first and second operating members, and can also rotate. When the first or second operating member moves, the tape-direction-changing piece rocks to allow the movement of the first or second operating member. When both the first and second operating members move at the same time, the tape-direction-changing piece moves together with the two operating members to press an operating force-transmitting member, prevented from rocking, thereby actuating a tape-feed-direction-changing mechanism.

Abstract: A movable element is attracted and displaced by an electromagnet against the resilience of a return spring to change a tape recorder from stoppage state into operation state. When the element is returned to its original position by the magnet, it moves so as to change the tape recorder from stoppage state into operation state. The return spring is so selected as to exert a force stonger than the attractive force, which acts on the movable element by the residual magnetism of the electromagnet, whereby the return of the element is achieved with certainty.In a case where a tape recorder is supplied with electric power from commercial power, when the supply of such power is cut off due to an accident, such as power failure, while the tape recorder is in use, a combination of a cam and a spring enables automatic restoration of the tape recorder to stoppage state.
