  • Patent number: 4497004
    Abstract: A picture reproducing apparatus for a helical scanning video tape recorder including an impedance transformer; a video head connected to the input of the impedance transformer; a resonance circuit connected to the output of the impedance transformer; a pre-amplifier connected to the output of the resonance circuit; a feedback resistor connected between the junction of the pre-amplifier and resonance circuit and the output of the pre-amplifier; and an output terminal connected to the output of the pre-amplifier. The impedance transformer has the output impedance four times as high as the input impedance thereof.

  • Patent number: 4466026
    Abstract: A record/reproduce circuit for VTR comprising two normal reproducing heads with different azimuth angles, a special reproducing head with the same azimuth angle as that of the one normal reproducing head, a rotary transformer through which signals from these heads are supplied to a static circuit section, a change-over means for alternately switching a signal from the special reproducing head and a signal from the other normal reproducing head with a different azimuth angle from that of the special reproducing head, a feedback type preamplifier for amplifying the output of the change-over means, and another feedback-type preamplifier for amplifying a signal from the normal reproducing head with the same azimuth angle as that of the special reproducing head.

  • Patent number: 3932687
    Abstract: A fibrous article having a suede-like surface is composed of numerous staple fiber bundle units mutually entangled with one another in a three-dimensional configuration. Each staple fiber bundle unit comprises a plurality of flexible and relatively movable synthetic organic ultrafine fibers having a substantially round cross-sectional profile, substantially the same fiber length, and lying axially along the longitudinal axis of the staple fiber bundle unit. Elastic bonding material is disposed around and spaced axially along the ultrafine fiber bundle units joining together adjacent ones of the ultrafine fiber bundle units at locations where they intersect with one another to jointly hold the entangled ultrafine fiber bundle units in their three-dimensional configuration while permitting slight relative longitudinal movement between the individual ultrafine fibers within each ultrafine fiber bundle unit.
