Abstract: A colorful fastener tape for a slide fastener chain and a fastener stringer comprising such a fastener tape have an ornamental portion arranged along an inner longitudinal edge of the fastener tape and formed by multicolored yarns. A multicolored cord or a number of multicolored yarns are woven or knitted into the fastener tape 1 along the inner longitudinal edge to produce a thickened reinforced section, thus producing an ornamental portion such as of rainbow colored. Fastener elements of various types may be fitted to the reinforced section of the fastener tape of the a fastener stringer, thus the fastener stringer has a beautiful ornamental portion. When multicolored yarns are used for several warps or warp knitting yarns located adjacent to the reinforced section, a broadened ornamental portion can be produced to enhance the color effect of the fastener stringer that may be used for a dress to improve its color effect.

Abstract: In a magnetic tape drive for a single-reel type magnetic tape cartridge having a leader block coupled to a leading end of a magnetic tape wound therein, a hub for winding the tape pulled out of the cartridge is disposed at rear side of a magnetic head unit for writing data on and reading data from the tape, and has a radial slot formed therein for receiving the leader block of the tape threaded through the unit. The rotational direction of the hub is determined such that the leader block is subjected to an radially-inward force in the slot of the hub at the beginning of a rotational movement of the hub, whereby slippage of the leader block from the slot of the hub can be prevented.

Abstract: Disclosed herein is a magnetic tape unit having a magnetic head for reading and writing data from and onto a magnetic tape. The magnetic tape is traveled in contact with the magnetic head during a read/write operation of the magnetic head. During a rest period where the read/write operation of the magnetic head is not performed, a reciprocating motion of the magnetic tape by a small distance is performed with a predetermined period. A temperature in the vicinity of the magnetic head is detected by a temperature sensor. The predetermined period is changed according to the temperature detected by the temperature sensor. Accordingly, the adhesion of the magnetic tape to the magnetic head can be well prevented irrespective of the temperature inside the tape unit.

Abstract: An apparatus for controlling the phase of a video signal has a track information detector for extracting track pair number data allotted to every N tracks from a reproduced signal when a rotary head is locked in phase with a reference signal, an FG generator, an FG counter for counting pulses of a capstan motor frequency signal, and a microcomputer for producing shift quantity data representing a shift quantity by which the rotary head is to be shifted to a target phase lock position, based on a value indicated by the track pair number data and a value indicated by the count from the FG counter, and controlling a capstan motor based on the shift quantity data, and output signals from a speed detector and a phase detector. The apparatus is capable of preventing an asynchronous condition from occurring upon switching between internal and external signals in an A/B editing process or the like.

Abstract: The developing agent comprises a colorant and vinyl-based polymer synthetic resin to which polyolefin waxes having softening points different from each other are added. Due to this softening point difference, the solidification time period for the waxes after fixation is prolonged; therefore the developing agent attains good fixation and anti-offset properties without deteriorating the preservation property and the fluidity of the developing agent.
