摘要： PURPOSE:To reduce the flickering on a screen and to obtain a high-fidelity bright TV picture, by dividing a video input signal into two groups in every one- field scanning time, and storing the signals after the one group is delayed by one-field scanning time, and then, alternately reading out the signals. CONSTITUTION:Video input signals are stored in memories 17 and 18 in such a way that the connection of the signals is changed over by a switch 15 at every one-field scanning time and one group of the signals are stored in the memory 17 after they are delayed by one-field scanning time at a delay circuit 16, and the other group is stored in the memory 18. The contents of the memories 17 and 18 are read out at a speed which is double of an ordinary horizontal scanning speed, and outputted after they are combined at a mixer 19. By successively scanning the video input signals at a scanning speed which is double of an ordinary speed without making any jumping scanning, a high-fidelity TV picture in which flickering is reduced is obtained.

摘要： PURPOSE:To secure the optical transmission via the light emitting element featuring the narrow linear region and the simple structure by omitting the linear driving of the light emitting element covering up to the area of the synchronous signal. CONSTITUTION:The video signal sent from input terminal 21 is amplified at video amplification part 22 and then applied to synchronous signal clamping circuit 24 to clamp the synchronous signal up to the pedestal level. And the clamped video signal is applied to one terminal of light emitting element driving part 25, and light emitting element 26 is driven by the output of part 25. At the same time, the video signal delivered from part 22 is applied to synchronous signal isolator circuit 23, and the synchronous signal isolated by circuit 23 is applied to the other terminal of part 25. And the output of element 26 is controlled down to the level near the cut-off only for the synchronous signal section, and the video signal output is delivered to optical transmission medium 27 at the video signal section. This optical signal transmitted is applied to level slicer 30 via light receiving circuit 29 and then converted into the binary signal by the light reception level. After this, the synchronous signal is regenerated at synchronous signal regeneration part 31 and then compounded with the video signal passed through amplification part 32 at signal compounding part 33. Thus the original signal is restored.

摘要： PURPOSE:To make it possible to record only a musical sound by automatically cutting a commercial message in recording a FM broadcasting program by sending a pilot signal while superposing data on the number of a sound to be recorded in its beginning and data indicating the end of it in its end. CONSTITUTION:When data received from data receiver 25 indicate a number code, UART processor 45 sends memeory read command signal F to memory control circuit 42. Memory control circuit 42 sends address signal G to memory 43 to read the contents of memory 43. If the contents of memory 43 agree with the number code, recording start signal J is outputted to tape recorder 12 via interface circuit 27. However, when the received data is an end control code indicating the end of the sound, UART processing circuit 45 sends pause or stop command signal H to the recorder. In this way, the desired sound can be recorded automatically and easily.

摘要： PURPOSE:To prevent the error transmission between frames and to make easy for frame synchronism, by constituting one character among one frame consisting of a plurality of characters as pause period. CONSTITUTION:One character consists of the start bit ST, stop bit SP and information bits b1 to b3. Further, one frame is composed of the characters ch1 to ch5, for example, and the character ch5 is taken as pause period and the information code is made as the same level as the stop bit SP. Further, frames Fi, Fi+1... are delivered continuously. In receiving this, if there is any error in the reception of character, the processor of the receiver resets the data reception unit, and if no error, pattern collation is made. If in agreement, the reception of next character is made. If the character synchronism is shifted, the data reception unit is reset. On the other hand, if fetched while being out of synchronism, since high level is continued for the pause period ch5 of the end of frame, no out of synchronism continues.

摘要： PURPOSE:To ensure the reproduction of the high-contrast characters and pictures free from flickering on the TV screen by providing the synchronous generating means with which the fixed relation is secured for the frequencies of horizontal driving signal, the vertical driving signal and the color subcarrier signal each. CONSTITUTION:The synchronous signal generating part is provided to generate signals HD, VD and SC featuring the relations of fS = m fH/2 (m: odd number) and fV = fH/n (n:odd number), where fH, fV and fS are frequencies to horizontal driving signal HD, vertical driving signal VD and color subcarrier signal SC respectively. For instance, signal SC is generated through 1/2 divider 6 and via oscillator 5 generating the signal of 2fS, signal HD is produced through 1/455 divider 7, and signal VD is generated through 1/263 divider 8 each. In this way, the phase of signal SC is turned by 180 deg. for each of even and odd fields, and at the same time the phase between scans is turned by 180 deg. even within the same field. This relationship is shown in Fig. A and B. As a result, the coloring of the white charcters can be prevented, thus obtaining a high-contrast and flickering-free characters and pictures.
