Filed: 1977-12-06
Abstract: PURPOSE: To adequately hold take-up quantity and feed quantity of tape by letting a servo loop perform servo action so as to make the contents of a counter zero thereby digitally controlling tape buffer quantity.  
     CONSTITUTION: A first digital tachometer 3 generates tacho pulses as a take-up motor 2 revolves. The pulses having been made to a suitable rate by a frequency divider 4 are made to FWD or RVS pulses according to the revolving directions of the motor 2 by a FWD-RVS pulse generating circuit 12, by which a counter 5 is counted up or down. The output of the counter 5 causes a feed motor 9 to revolve by way of a D/A converter 6, compensation circuit 7 and power amplifier 8. The pulses being generated by a second digital tachometer 10 coupled to the shaft of the motor 9 are made by the FWD or RVS pulses by a FWD-RVS pulse generating circuit 11 to add or subtract the contents of the counter 5 so that they become zero. The output of the counter 5 is supplied to the motor 9. Hence, the take-up quantity and feed quantity of the tape may be adequately maintained.

Filed: 1984-07-16
Abstract: PURPOSE:To improve the aperture efficiency by providing a discontinuous face to a waveguide path, adjusting the length from the discontinuous face of the conductive path to the aperture face so as to adjust the amplitude ratio of two basic and high-order propagation modes and the relation of phase. CONSTITUTION:The antenna consists of metallic plates 5, 5' provided with a slot waveguide 1 and discontinuous face 4. The width A' of the metallic plate 5' is selected as A'<1.5 wavelength and the guide 1 is made coincident with the center axis 6, then the mode existing between the metallic plates 5' is only the basic propagation mode. The basic propagation mode generates a high-order propagation mode from the face 4 and when the distance A of the metallic plates 5 is taken as <=2.5 wavelength, the mode propagated between the metallic plates 5 is the basic propagation mode and the 3rd-order propagation mode. Thus, in selecting the length L of the metallic plate 5 to a length where two modes are shifted by the phase by 180 deg., the two modes are overlapped in opposite phase at the aperture face and the aperture distribution close to uniform distribution is obtained.
