An apparatus for performing relative to an elongate information carrier initially located in a casing a predetermined function outside of the casing has a mechanism for moving a length of the elongate information carrier relative to the casing. A drive for the moving mechanism is provided and a device for transmitting driving power to the moving mechanism is connected between the drive and the moving mechanism. A control device is coupled to the transmitting device for controlling the moving mec...

An information retrieval system is provided with first and second detectors for detecting a frame and group marks located at one side of the recorded film band, a counter for counting the detecting marks and a recorded band feeding apparatus connected to the counter to receive a control signal therefrom. The counter counts down the predetermined value being set, and when the counter has counted the group marks in number equal to the number of the predetermined number of frames, the counter produ...

Identifying information is stored or recorded on a recording element and camouflaged by recording the identifying information on a recording element through an information transformation medium such as a lenticular plate and then camouflaging the recorded information by recording the information on the same recording element through the information transformation medium, disposed at a different position than that used in recording the identifying information thereby concealing the identifying in...

The information recording apparatus comprises an input device for continuously printing on a recording tape encoded character information and encoded left and right margin position designating information which is used to determine the width of a space on a recording paper in which the encoded character information is to be printed; and a printing device having means for designating the left and right margin positions of a printing device on the recording paper in accordance with the left and ri...

A time sharing information transmission circuit suitable for an integrated circuit employing insulated gate field effect transistors. The circuit comprises a time sharing circuit including the desired number of clocked inverters in accordance with input information being time shared, a restoring circuit including said desired number of clocked inverters in accordance with the time shared signals being restored, and a transmission line to transmit said time shared signal.

Method of evaluating information in the form of linecoded grouped information bits, and to a coding arrangement device for presenting information for evaluation by such method.

The device employs a pair of elongated, relatively superposed, roadway route information strips, each of which has longitudinally successive indicia of a roadway route thereon, the roadway of which in actuality undergoes a turn at an intermediate point in the space between spaced points thereon. The spaced points and the intermediate point of the roadway are represented by the indicia, however, as lying on a rectilinear course of travel lengthwise of the strip; and the distances between the resp...

An optical information retrieval apparatus which utilizes the correlation detection function of a hologram to check coincidence matching between an interrogation signal and information recorded in a hologram memory is provided with an acousto-optic deflector serving as an input means for the interrogation signal. Both the interrogation signal and the hologram memory information are represented in the form of an M-out-of-N code, and identification of coincidence matching therebetween is effected ...

For manfacturing a (video) long-playing record a plate is coated with a photoresist and rotated underneath a laser beam which is turned on and off in accordance with the information. In particular a glass mother provided with a pattern etched in an oxide is obtainable in this manner.

In an information transmission system a shift register controlled modulator matrix is employed for simultaneously performing a modulating and a filtering process to reduce unwanted modulation products and harmonics. By employing a shift register controlled modulator matrix with a shift register having an input combination device coupled to an information source and through weighting devices to elements of this shift register, the size of the modulator matrix is reduced.
