  • Patent number: 7264760
    Abstract: Tips of the lug portions of a board touch the bottom of the opening between projecting portions and step portions, when the upper mold and the lower mold are fit together with a battery and board inserted. Thus the board is retained in position in the molds certainly. After the molds are fit together, polyamide resin is injected into a molding space from a resin-material-injecting orifice provided in the upper mold.

  • Patent number: 4500921
    Abstract: A television system includes a transmitting station transmits a TV signal after adding a pilot carrier having a frequency within the video signal band to the video signal and includes a receiver which selectively takes out the pilot carrier by means of a bandpass filter and uses the pilot carrier as an AGC reference signal.

  • Patent number: 4463376
    Abstract: A television signal processing system characterized in that a level of at least a portion of a blanking interval of a coded television signal is shifted towards a white level and falling of the level shifting interval is shaped into a smooth waveform.

  • Patent number: 4398215
    Abstract: A video signal processing system in which a synchronizing signal component of a television video signal is inverted with reference to a pedestal level and expanded higher than a video component and horizontal synchronizing signals are reduced so that each of the horizontal synchronizing signals may correspond to plural lines.

  • Patent number: 4390899
    Abstract: A television signal processing system characterized by coding operation which comprises inverting synchronizing signal components of a television signal with reference to a pedestal thereof, expanding the synchronizing signal components to such an extent that they do not exceed a peak value of a video signal component and reducing horizontal synchronizing signals so as to leave one per several lines.

  • Patent number: 4369462
    Abstract: A coding system for use in a television system wherein at least a part of a television signal is inverted by an encoder at a broadcasting station, according to a code signal and the coded television signal is decoded by decoders of specific subscribers to be reproduced on TV sets. The coding system is comprised of a clock oscillation means, a mode generating means for generating signals indicating plural inversion modes, a counter for counting clock signals from the clock oscillation means, a setting means for outputting a predetermined signal based on addresses provided corresponding to the respective inversion modes of the mode generating means and determined by an output from the counter, and a means for inserting the code signal during a vertical blanking period of the television signal. When the output signal of the mode generating means and the output signal of the setting means are in a given relation, the count value of the counter is used as the code signal.

  • Patent number: 4363003
    Abstract: A PLL circuit which comprises a phase comparator, a voltage-controlled oscillator whose oscillation frequency is controlled by an output from the phase comparator, a flip-flop circuit adapted to be set by an input signal, and a counter circuit responsive to an output condition of the flip-flop circuit to count an output from the voltage-controlled oscillator. The flip-flop circuit is adapted to be reset by an output from the counter circuit, and the phase comparator is adapted to receive an output from the flip-flop circuit and the output from the voltage-controlled oscillator.

  • Patent number: 4308556
    Abstract: A video signal scrambling system for use with a pay television system in which video signals are scrambled so that only specified subscribers can receive the program. Inversion of the video signal level for scrambling is performed only when the average gradation of the video signals varies relatively largely so that flickering is eliminated from the reproduced picture.
