摘要： The invention relates to a magnetic recording and reproducing apparatus for eliminating the crosstalk component from an adjacent track and obtaining a high picture quality. Chrominance signals in the base band which are produced by a low frequency conversion chroma signal are supplied to comb-shaped filters which are used in the magnetic recording and reproducing apparatus. The chrominance signals in the base band are obtained by generating (25 to 36) carriers (ø₁, ø₂) synchronized with a burst signal of the low frequency conversion chroma signal including the jitter component upon reproduction and by multiplying (5, 6) the carriers (ø₁, ø₂) and the low frequency conversion chroma signal. A burst signal portion between the resultant chrominance signals in the base band is applied as a frequency control input signal to an oscillator as the carrier generating source (25 to 36), so that desired carriers (ø₁, ø₂) are derived. Thus, the frequency fluctuation is eliminated from the converted chrominance signal in the base band and the high picture quality can be realized.
摘要翻译：本发明涉及一种用于消除来自相邻轨道的串扰分量并获得高图像质量的磁记录和再现设备。由低频转换色度信号产生的基带中的色度信号被提供给在磁记录和再现设备中使用的梳形滤波器。基带中的色度信号是通过在再现时产生包括抖动分量的低频转换色度信号的突发信号同步产生（25至36）个载波（φ1，φ2）并将载波（5,6）乘以（ø1，ø2）和低频转换色度信号。将基带中所得到的色度信号之间的色同步信号部分作为频率控制输入信号加到作为载波发生源（25至36）的振荡器上，从而得到所需的载波（φ1，φ2）。因此，从基带中的转换后的色度信号中消除了频率波动，并且可以实现高图像质量。

摘要： An audio signal transmission system having a noise reduction circuit (6), which includes a transmission medium (101) such as a magnetic tape to be used to transmit a digital signal converted from an input audio signal and thereafter to output the audio signal reproduced from the digital signal, a digital signal transmitter having a pulse-code modulator and demodulator (MODEM) (9). The noise reduction circuit (6) includes a compressor (20) for compressing the dynamic range of the input audio signal according to the detection level obtained by detecting at least the high-frequency components thereof in order to supply the output from the compression to the digital signal transmitter and an expan- ,der (21) for expanding the dynamic range of the demod-I ulated signal from the transmitter according to the detection level of at least the high-frequency components thereof. The transmission system has a low-pass filter which limits the frequency band of the input signal to be supplied to the dynamic-range compressor (20) to at most half the sampling frequency of the MODEM (9) and thus permits the noise reduction circuit (6) to compress and expand signals supplied thereto in the same frequency band without causing any erroneous operation.

摘要： An imaging and recording apparatus for electrically recording an optical image of a subject as an image information signal which facilitates memory access from an external device and prevents image information from being changed. Upon manipulation of a recording trigger switch (5), an image outputted from a camera signal processing circuit (17) at that time is written into a semiconductor memory (12), then subjected to data compression in a data compression circuit (21), and stored in a semiconductor memory (13). It is now assumed that an external device not illustrated is connected to a connector (14) and this external device orders taking in the image of the semiconductor memory (13). If at this time the semiconductor memory (13) is writing an image, a state detection circuit (23) detects the fact and inhibits the external device from taking in the image. Furthermore, while the external device is taking in the image of the semiconductor memory (13), the state detection circuit (23) detects this fact. Even if the recording trigger switch (5) is manipulated, an AND gate (6) turns off in response to an output of the state detection circuit and inhibits image writing into the semiconductor memory (13).

摘要： A terminal 2 held by the user is provided with a radio transmitter and receiver 3. Electronic money information is transferred via the radio transmitter and receiver 3. By using a portable telephone, it is unnecessary to directly insert an IC card 1 into service supply equipment 17. In addition to the service supply equipment 17, a device 9 for storing electronic money information in a lump is provided. Since the electronic money information is transferred into the device 9 for storing the electronic money information in a lump, it is unnecessary to collect the electronic money information stored in terminals one by one.
