Electrical Symbols — Delay Elements

"The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers. The US standard symbols are outlined by the American National Standards Institute and the American Welding Society and are noted as "ANSI/ AWS".
In engineering drawings, each weld is conventionally identified by an arrow which points to the joint to be welded. The arrow is annotated with letters, numbers and symbols which indicate the exact specification of the weld. In complex applications, such as those involving alloys other than mild steel, more information may be called for than can comfortably be indicated using the symbols alone. Annotations are used in these cases." [Symbols and conventions used in welding documentation. Wikipedia]
The example chart "Elements of welding symbol" is redesigned using the ConceptDraw PRO diagramming and vector drawing software from the Wikipedia file: Elements of a welding symbol.PNG.

The vector stencils library Map symbols contains 19 icons for labeling the maps using the ConceptDraw PRO diagramming and vector drawing software.
The vector stencils library Subway map contains 41 shapes for creating the subway (tube, metro) maps using the ConceptDraw PRO.
"The various features shown on a map are represented by conventional signs or symbols. For example, colors can be used to indicate a classification of roads. Those signs are usually explained in the margin of the map, or on a separately published characteristic sheet.
Some cartographers prefer to make the map cover practically the entire screen or sheet of paper, leaving no room "outside" the map for information about the map as a whole. These cartographers typically place such information in an otherwise "blank" region "inside" the map -- cartouche, map legend, title, compass rose, bar scale, etc. In particular, some maps contain smaller "sub-maps" in otherwise blank regions—often one at a much smaller scale showing the whole globe and where the whole map fits on that globe, and a few showing "regions of interest" at a larger scale in order to show details that wouldn't otherwise fit."

The vector stencils library "IDEF3 process schematic symbols" contains 12 shapes: unit of behavior (UOB), links, junctions, .
Use it to design your IDEF3 process schematic diagrams.
"Process schematics tend to be the most familiar and broadly used component of the IDEF3 method. These schematics provide a visualization mechanism for processcentered descriptions of a scenario. The graphical elements that comprise process schematics include Unit of Behavior (UOB) boxes, precedence links, junctions, referents, and notes. The building blocks here are:
- Unit of Behavior (UOB) boxes.
- Links: Links are the glue that connect UOB boxes to form representations of dynamic processes.
- Simple Precedence Links: Precedence links express temporal precedence relations between instances of one UOB and those of another.
- Activation Plots: Activation plots are used to represent activations.
- Dashed Links: Dashed links carry no predefined semantics.
- Link Numbers: All links have an elaboration and unique link numbers.
Activation Semantics for Nonbranching Process Schematics.
- Junctions: Junctions in IDEF3 provide a mechanism to specify the logic of process branching.
- UOB Decompositions: Elaborations capture and structure detailed knowledge about processes.
- UOB Reference Numbering Scheme: A UOB box number is assigned to each UOB box in an IDEF3 Process Description.
- Partial Descriptions: UOB boxes are joined together by links. Because of the description capture focus of IDEF3, it is possible to conceive of UOBs without links to other parts of an IDEF3 schematic.
- Referents: Referents enhance understanding, provide additional meaning, and simplify the construction (i.e., minimize clutter) of both process schematics and object schematics." [IDEF3. Wikipedia]
The shapes example "Design elements - IDEF3 process schematic symbols" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the solution "IDEF Business Process Diagrams" from the area "Business Processes" of ConceptDraw Solution Park.

The vector stencils library "Astronomical symbols" contains 58 astronomical symbols and astrological signs of Solar system planets, stars, Sun, Moon, Earth, constellations, Mercury, Venus, Mars, Saturn, Jupiter, Uranus, Neptune, comet, Zodiac signs.
"Astronomical symbols are symbols used to represent various celestial objects, theoretical constructs and observational events in astronomy. The earliest forms of these symbols appear in Greek papyri of late antiquity. The Byzantine codices in which the Greek papyri were preserved continued and extended the inventory of astronomical symbols. New symbols were further invented to represent many just-discovered planets and minor planets discovered in the 18th-20th centuries.
All these symbols were once commonly used by professional astronomers, amateur astronomers, and astrologers. While they are still commonly used in almanacs and astrological publications, their occurrence in published research and texts on astronomy is relatively infrequent, with some exceptions such as the Sun and Earth symbols appearing in astronomical constants, and certain zodiacal signs used to represent the solstices and equinoxes."

Use it to design your sales flowcharts, workflow diagrams and process charts by the ConceptDraw PRO diagramming and vector drawing software.
"A sales process is an approach to selling a product or service.
... a "sales process" is presented as consisting of eight steps. These are:
(1) Prospecting / initial contact,
(2) Preapproach - planning the sale,
(3) Identifying and cross questioning,
(4) Need assessment,
(5) Presentation,
(6) Meeting objections,
(7) Gaining commitment,
(8) Follow-up." [Sales process. Wikipedia]

The vector stencils library "Delay elements" contains 12 symbols of delay elements for drawing electrical schematics and electronic circuit diagrams.
"An analog delay line is a network of electrical components connected in series, where each individual element creates a time difference or phase change between its input signal and its output signal. It operates on analog signals whose amplitude varies continuously. An example is a bucket-brigade device. Other types of delay line include acoustic, magnetostrictive, and surface acoustic wave devices. A series of RC networks can be cascaded to form a delay. A long transmission line can also provide a delay element. The delay time of an analog delay line may be only a few nanoseconds or several milliseconds, limited by the practical size of the physical medium used to delay the signal and the propagation speed of impulses in the medium."
