  • Patent number: 5731925
    Abstract: An apparatus arranged to pull out a tape stowed in a cassette and to cause the tape to abut on a head so as to enable the head to record or reproduce information on or from the tape includes a rotary drum on which the head is mounted, a first chassis on which the rotary drum is disposed, and a second chassis arranged to be relatively movable with respect to the first chassis and to have first and second pull-out members arranged thereon to pull out the tape from the cassette. At the beginning of loading the tape, the tape is pulled out from the cassette by the first pull-out member. Then, after the tape is pulled out a predetermined amount by the first pull-out member, the tape is further pulled out by the second pull-out member.

  • Patent number: 5729200
    Abstract: A material used to form a biasing element for a magnetomechanical EAS marker has a coercivity that is lower than the coercivity of biasing elements used in conventional magnetomechanical markers. The marker formed with the low coercivity material can be deactivated by applying an AC magnetic field at a level that is lower than is required for deactivation of conventional markers. The marker with the low coercivity bias element can also be deactivated when at a greater distance from a deactivation device than was previously practical.

  • Patent number: 5721792
    Abstract: In accordance with the principles of the present invention, the above and other objects are realized in an apparatus and method for superimposing text information on a video background signal. The apparatus includes means to input the video background signal, a text generator for generating a text signal containing the text information to be superimposed on the video background signal and automatic contrast circuit means for selectively controlling the brightness of the text signal to maintain at least a predetermined minimum contrast between the brightness of the text signal and the brightness of the video background signal as the brightness of the video background signal varies. The automatic contrast means maintains at least a predetermined minimum contrast by adding a predetermined amount of brightness to a first text signal generated by the text generator above the brightness of the video background signal to provide a second text signal for superimposing on the video background signal.

  • Patent number: 5718278
    Abstract: A process for fabricating a hollow or partially hollow article, such as a jewelry ring, comprises producing a first mold having an inner cavity shaped in accordance with the external shape of the article to be produced. A second mold is produced for forming a wax core insert which is inserted in the first mold cavity for forming the hollow region of the article. The second mold has an inner cavity formed in the shape of, but slightly smaller than, the external shape of the article. The cavity of the second mold has holes which form spacer pins on the wax core insert. The wax core insert is then placed in the cavity of the first mold and is maintained in a precise, predetermined position by the spacer pins. During waxing of the article, a plastiwax is introduced into and fills the cavity of the first mold, completely surrounding the wax core insert. The plastiwax hardens and is removed from the first mold cavity with the wax core insert.

  • Patent number: 5719984
    Abstract: A recording apparatus for recording a video signal on a recording medium together with data signals relative to the video signal comprises a first signal processing channel in which the data signals are supplied to a monitor in a state of being superimposed on the video signal, a second signal processing channel in which the data signals are supplied to the monitor without being superimposed on the video signal and a selector which selectively renders the first signal processing channel or the second signal processing channel operative. Where a display of the recording video signal on the monitor is excessively covered and hidden by that of the data signal, the second signal processing channel is selected and operated to permit adequate visual confirmation on the monitor of the video signal to be recorded.
