A coded signal reproducing device for a video tape recorder wherein a PCM recorder is used for the audio signal and wherein sometime the VTR is set to variable speed reproducing mode for various purposes. The present invention utilizes a counter for counting a predetermined number of data in synchronization with a reference signal positioned between a vertical synchronizing signal and data in a coded signal having the format of a video signal reproduced at a different speed from the recording sp...

A display device has a display panel in which patterns are impressed in conformity to the layout of a master instrument. With this display device, a pattern indicating a prescribed condition of the master instrument which is to be detected and a pattern representing a countermeasure for the prescribed condition are impressed on the display panel. Patterns related to the conditions of the master instrument which can be coped with without cutting off a power switch are displayed in a first color a...

In the disclosed communication system the digital message bits (e.g., data bits) to be transmitted to a particular receiver are individually encoded in the digital address (of K bits) of that receiver. The receiver has a K(stage) correlation circuit which serves to correlate all incoming message information with its own digital address. In the case of a match, autocorrelation peaks appear at intervals determined by the digital message. A feature is to transmit each address sequence a number of t...

A transfer plug system for electrical or electronic controls or devices having coding parts which correspond to one another mechanically and are attached at a cable housing as well as in the area of a counter-plug element, the coding parts being brought into engagement with one another and held by means of a shared locking element, the locking element thus operating to fulfill a dual function of coding for preventing faulty plugging and of fastening and locking the plug housing at plates or in a...

The tools (wrenches) of this invention provide a one color instant identification of color coded tools. Preferably, the tools have a portion of their outer surface colored. Typically, the color impregnates the metal or plating during the manufacturing process. Another embodiment is a colored applique, band or sleeve on the outer surface of the tools. The key of this coloring is to identify the tool quickly by coloring a large area of the tool. This provides for quick identification of the tool e...

A test device which includes a housing having an immunochromatographic test strip therein is disclosed. The test strip is color-coded so that the presence or absence of a substance or substances in a fluid sample may be detected and identified. The strip also indicates the locations of the immunoreactions that will take place on the test strip by means of colored lines. Sample is applied onto the strip through a window and is spontaneously wicked up the test strip mobilizing a dye-microspherical...

A transmitter includes a repetition encoder generating repetition code sequence having a word length of r bits by carrying out a repetition coding with respect to 1 bit of a transmission unit which divides transmission information by a predetermined word length, where a rate of the repetition coding is set equal to a reciprocal of a predetermined integer r. A tree encoder generates a tree code sequence by carrying out a tree coding with respect to the other bits of the transmission unit, where a...

Tubing for use with intravenous delivery of fluids to a patient is provided. The tubing is preferably see-through and includes a tubing wall defining an exterior surface and an interior surface. The interior and exterior wall surfaces define a channel for transferring intravenous fluid. An indicator for visibly distinguishing one tube from another similar tube is provided. The visible indicator may be a protruding ridge or a depression that traverses a length of the exterior surface, wherein the...

A perpetual symbol coded means for calendaring, presenting--in one embodiment--a two dimensional matrix which graphically presents the basic information of the month, day and date for a given year. Correlation of the basic calendaring data is achieved by way of a matrix, whereby a column arrays monthly data, another columnar arrangement offers day information for consideration and a yearly designator appears as a legend or heading. A method of use, including a means for extrapolation of any desi...

A color coded indexing system to facilitate filing and retrieval of documents comprising two 10-position digital bars spaced longitudinally from each other on each opposed surface of an edge portion of each document and each successively displaying in its 10 positions the numerals 0-9, with those on the obverse surface closely adjacent the document edge and those on the reverse surface offset inwardly from the edge; and 10 sets of separable color coded single digit tabs with each set having a di...
