Abstract: PROBLEM TO BE SOLVED: To put noncontact communication to practical use within a legally authorized weak wadio wave range. SOLUTION: The noncontact communication system comprises a first noncontact transmitter/receiver for reading/writing data, and a second noncontact transmitter/receiver having a function for storing/reading that data wherein communication between the first noncontact transmitter/receiver and the second noncontact transmitter/receiver is effected by transmitting an electric signal representative of that data through electromagnetic coupling of an antenna resonance circuit provided in each transmitter/receiver. The first noncontact transmitter/receiver comprises a signal source of a carrier signal for carrying the data signal and the second noncontact transmitter/receiver comprises a signal source of carrier signal.

Abstract: PROBLEM TO BE SOLVED: To reproduce a signal on electromagnetic conversion with different required band characteristics satisfactorily (by improving C/N) by using the same head and a rotary transformer, and to prevent costs from being increased and constitution from being made large-scaled. SOLUTION: At the time of reproducing a digital signal or an analog signal from a magnetic tape by using the same head rotary system 3, an additional capacitance Cs included in a resonance capacitor Ct is controlled by a mode control signal mc corresponding to which of the analog signal and the digital signal should be reproduced so that head resonance frequencies decided from an equivalent inductance Lt of the head rotary system 3 and the resonance capacitor Ct can be varied. Also, when any distortion is developed in signal amplitude and a phase due to the variation of the head resonance frequencies, a feedback gain Ka of feedback dumping is varied or switched from the mode control signal mc so that optimization can be attained.

Abstract: PURPOSE:To properly set a recording current with a simple configuration by properly setting the recording current characteristics for the recording frequency in a recording amplifier for each type of recording tape. CONSTITUTION:A video tape discrimination circuit 17 judges the potential of a signal supplied from a video tape type detection switch 16, discriminates the type of a fitted tape cassette, and then outputs a discrimination signal of '1' or '0' according to the discrimination type. A characteristic voltage setting circuit 18 sets a predetermined voltage according to the discrimination signal and a frequency characteristic voltage generation circuit 19 generates the control voltage of a recording amplifier according to the set voltage and then supplies it to a terminal 2c. The control voltage of the terminal 2c causes the frequency characteristics of the recording current output from a recording amplifier 3 in a recording/reproduction amplifier 2 to be controlled.

Abstract: PURPOSE:To excellently prevent an inversion phenomenon due to a lower side- band emphasis effect and separation loss. CONSTITUTION:A luminance FM signal YFM is supplied to an adder 12 comprizing an inversion prevention circuit 11 and the output signal of the adder 12 is supplied to a filter 13. The filter 13 has the amplitude characteristics of a+bsin omegatauD/2 and generates a delay of tauD. The tauD is set so as to satisfy a formula of f=1/2tauD, assuming that 'f' is a frequency to be compensated for inversion prevention. The output signal of the filter 13 is supplied to the adder 12 via a limiter 14 and the series circuit of an attenuator 15 to subtract it from the luminance FM signal. When the luminance FM signal level is large, the inversion phenomenon due to the lower side-band emphasis effect can be prevented by equalizing the amplitude in a linear phase. When the luminance FM signal level is small, a boost operation of the frequency 'f' to be compensated for inversion prevention is conducted and thus, the inversion phenomenon due to the large separation loss instantly generated can be prevented.

Abstract: PURPOSE:To realize the video camera able to obtain an image pickup signal by multiple exposure for each field. CONSTITUTION:A shutter pulse SHP is fed twice intermittently to an image pickup element for a first half of each field period for each prescribed period. The sensor gate pulse SGP is supplied twice for the half period accordingly. A signal charge stored in a sensor of the image pickup element 1 is synthesized sequentially on a vertical shift register. A transfer pulse is fed to the image pickup element 1 for the latter half of each field period, the synthesis charge is transferred at a speed twice the usual speed and the image pickup signal by one field by multiple exposure is outputted. The image pickup signal is written in a memory 10 and transferred to a buffer memory 11 and the signal is read at a speed a half of the write speed from the buffer memory 11 and the image pickup signal is restored to the usual time axis. the video signal of the usual time axis due to multiple exposure is obtained for each field at an output terminal 8.

Abstract: PURPOSE:To attain a video tape recorder of four-head system at a low price by connecting two of the four video heads in series, and using a three-channel rotary transformer. CONSTITUTION:During the time of recording, a swiching switch 3 is switched by a switching pulse P3 that inverts its level between a high and a low levels at every one-field period(1F), and a changeover switch 4 is fixed in a changeover switch 3-side, and the recording is executed by selectively switching the video heads 1A and 1B at every 1F. During the time of standard-speed reproducing, the heads 1A and 1B are selectively switched similarly. During the time of double-speed reproducing, the switch 3 is switched by the pulse P3, and at the same time, switch 4 is switched by a switching pulse P4 whose period is half that of the pulse P3, and the heads 1A, 1B, 2A, and 2B are sequentially and selectively switched at every 1/2F. During the time of sextuple-speed repro ducing, a pulse P4 whose period is 1/6 of that of the pulse P3 is supplied to the switch 4.

Abstract: PURPOSE:To compensate the frequency characteristics of a comb line filter and to separate a luminance signal with generally flat characteristics, by feeding back an output of an attenuator to the attenuator through a filter circuit. CONSTITUTION:A color video signal (a) from an input terminal 1 is inputted to a 1H delay line 4 and an adder 5. A signal (b) delayed by 1H in the delay line 4 is added to the adder 5 and a luminance signal (c) separated by a comb line filter 3 is supplied to a synthesizing device 7. An output of said device 7 is sent to an output terminal 2 to output as a luminance signal (d'). The luminance signal (d') is inputted to a filter circuit 8 with the same frequency characteristics as the pass frequency characteristics of the delay line 4 and the output of the filter circuit 8 is fed back to the synthesizing device 7. Thus, the frequency characteristics of the comb line filter 3 in the delay line 4 is compensated, outputting the luminance signal with generally flat characteristics.

Abstract: PROBLEM TO BE SOLVED: To realize a wideband characteristic with a shape of a high degree of freedom.
SOLUTION: Radiation plates 1a and 1b are adjacently arranged with a symmetrical line L as a boundary so as to have a gap 21 having a prescribed gap length. The gap 21 is formed so as to be gradually widened toward an opened end (cut opening) with a power feeding part 3 as a basic point. The power feeding part 3 is provided at a prescribed position near an opened end (cut opening at the lower end of the radiation plates 1a and 1b) in the slot longitudinal direction of the gap 21 and receives power from an unillustrated coaxial feeding cable. When the full length in the slot longitudinal direction is defined as s, the distance f from the opened end of the gap 21 to the power feeding part 3 is made to be s/3±10%. This invention is applicable to a wideband antenna device.
