摘要： A programmable time code generator utilizes a synchronous parallel-to-serial data converter for conversion of time code in parallel form into serial form. The resulting longitudinal time code is suitable for recording on magnetic tape in synchronism with an information signal. The time code generator can be readily adapted for various video recording formats, such as NTSC, PAL, PAL-M, SECAM, etc., as well as for synchronous time code generation in other types of recording. In addition, the frequency of the generated longitudinal time code can be changed in a simple manner to be adapted for recording at various tape speeds which are different from the normal playback speed.

摘要： Disclosed is a position-measuring transformer formed from two relatively movable members. The transformer is particularly useful for selecting and defining track positions in a magnetic disc drive system which may be used as a memory in a digital computer. One stationary member of the transformer includes cofunction windings and end-detecting windings. Those windings magnetically coupled to a reference winding on another relatively movable member of the transformer. The reference winding, which is the continuous winding of the transformer, is formed from a plurality of equally spaced active conductors. The active conductors are interconnected such that alternate ones conduct in opposite directions so that each pair of adjacent active conductors define a reference cycle. The end-detecting windings consist of one or more pairs of active conductors where the active conductors in each pair have full-cycle spacing, that is, the separation between each active conductor in a pair equals one reference cycle. The full-cycle spacing of the end-detecting winding superposed over the half-cycle spacing of the enddetecting winding induces a substantially zero resultant signal in the end-detecting winding except when the end-detecting winding is positioned over the end conductor of the reference winding as may occur when the reference winding is moved. When over the end, a limit signal is generated as a result of the unequal coupling between the end-detecting winding active conductors and the end conductor of the reference winding. The limit signal thus generated typically defines the inner or outer limit of a read/write head. Cofunction windings are formed from four winding sections with equal numbers of active conductors per section. The cofunction windings are formed using an efficient winding pattern which minimizes the number of welded or soldered connections required.

摘要： A display device for a magnetic tape recording and/or reproducing apparatus, comprises a pulse generating circuit for generating a pulse signal having a frequency which is in accordance with a rotational speed of a capstan which drives a magnetic tape to travel in a state where the magnetic tape is pinched between the capstan and a pinch roller, a counter for counting the pulse signal from the pulse generating circuit, and an indicator for displaying a counted result in the counter. The counter counts the pulse signal from the pulse generating circuit so as to obtain a counted result which would result in a real-time display on the indicator. The indicator displays in real-time, a tape travel quantity of the magnetic tape which is driven to travel by the capstan.

摘要： Apparatus for indicating the farthest advance position of a bi-directionally movable medium is provided with a pulse generator mechanically coupled to the medium to generate pulses corresponding to incremental movements of the medium in either a first or second direction. The actual direction in which the medium moves is represented by respective first and second signals. A counter incrementally changes its count in response to each generated pulse when the medium moves in, for example, the second direction, and the counter reverses the direction in which it counts when the medium moves in the first direction following medium movement in the second direction so that the counter incrementally is restored to an initial count. Once the initial count of the counter is restored, an output farthest advance signal is produced indicating that the medium has reached its farthest advance position. In one embodiment, the apparatus is used to indicte the farthest advance of a movable web. When the web is reversed, the counter is decremented from an initial predetermined count. When the web subsequently is moved forward, the counter then is incremented. Once the web reaches the farthest advance position previously occupied prior to reverse movement thereof, the counter concurrently reaches its initial, predetermined count.

摘要： A control system is proposed which is of more special but not exclusive application to the dispatching of articles on a conveyor and where the conveyor can be carrying many objects at one time which are destined for discharge at different points. Dispatching of an object is accompanied by entry into a computer type store of a count representation and a representation which identifies the action to be performed when the count representation has been decremented to a significant value. Decrementing of the count representation is effected after predetermined elapsed intervals or events which in the case of the conveyor system correspond to set distances covered by the conveyor.

摘要： An endless magnetic tape playing time indicating apparatus for an endless magnetic tape player is provided with pointer means rectilinearly moved by rotatable force of a rotary drive capstan for driving the tape, and indicator means including scale means corresponding to the pointer means. Provided between the pointer means and the rotary capstan are a speed reducing device decelerating rotation of the capstan, drum means rotatably driven through the speed reducing device by the capstan, and a flexible stringy member taken up by the drum means with rotation of the capstan, the pointer means being rectilinearly moved when the flexible stringy member is wound on the drum means. The flexible stringy member is drawn from the drum means whenever the magnetic tape completes one cycle to thus return the pointer means to its starting position.

摘要： As described herein, a multiple frequency time code generator generates sequentially at least two series of time code signals for separately identifying the television information signals with which both series of time code signals are associated. The time code signals have different frequencies and are adapted to be recorded on a separate track of a video tape recorder and reproduced therefrom at tape speeds ranging from 1.5 inches per second (ips) to 450 ips. A reader separates the reproduced time code signals into different output channels.
