Many lengths of bias-cut fabric can be pieced together into a long "tape", which is typically sold in metre or roll lengths by haberdashers. Bias tape varies in width from extremely narrow (1 ⁄ 4 in [0.6 cm] wide when flat) to extremely wide (as wide as 3 in [7.6 cm] or more). Bias tape is used in making piping, binding seams, finishing raw ...
A conventional tape recorder uses two heads. The main head is used for both playback and recording. A second head, placed before the main head in terms of the direction of tape movement, is used during recording to erase any previous signal. Additionally, the record head is used to introduce a tape bias signal that improves frequency response.
From the end user viewpoint, the IEC 60094 defined two principal properties of each tape type: Bias level for each type was set equal to the optimal bias of the relevant IEC reference tape, and sometimes changed when the IEC changed the reference tapes, though the BASF datasheet for the Y348M tape, approved as the IEC Type I reference in 1994 ...
Combinations of bias methods may be used on the same tube. Fixed bias: The DC grid potential is determined by connection of the grid to an appropriate impedance that will pass DC from an appropriate voltage source. [2] [4] Cathode bias (self-bias, automatic bias) - The voltage drop across a resistor in series with the cathode is utilized. The ...
The magnetic tape is marked and cut with a blade. Adhesive tape is applied to the back side of the magnetic tape which secures the edit. Tape editing is performed simply by cutting the tape at the required point and rejoining it to another section of tape using adhesive tape, or sometimes glue; it is called a splice. The adhesive tape used in ...
The endless loop tape cartridge was designed in 1952 by Bernard Cousino of Toledo, Ohio. [6] [7]Previously, music in the car had been restricted mostly to radios. Records, due to their methods of operation and size, were not practical for use in a car, although several companies tried to market automobile record players such as the Highway Hi-Fi and the Auto-Com flexidisc.
A bias tee is a three-port network used for setting the DC bias point of some electronic components without disturbing other components. The bias tee is a diplexer.The low-frequency port is used to set the bias; the high-frequency port passes the radio-frequency signals but blocks the biasing levels; the combined port connects to the device, which sees both the bias and RF.
Tape measures are often designed for specific uses or trades. Tapes may have different scales, be made of different materials, and be of different lengths depending on the intended use. Tape measures used in tailoring are called "sewing tape". Originally made from flexible cloth or plastic, fiberglass is now the preferred material due to its ...
