摘要： PURPOSE:To obtain a sinusoidal frequency modulation signal of object frequency by using a rectangular wave oscillation circuit, a frequency division circuit and a shift circuit so as to generate a 1st rectangular wave signal of an object frequency and a 2nd rectangular wave signal retarded by 1/6 period and adding the 1st and 2nd rectangular wave signals so as to eliminate harmonic com ponents. CONSTITUTION:A 3rd harmonic components S13, S23 included in the 1st rectan gular wave signal S1 and the 2nd rectangular wave signal S2 whose phase is retarded by 1/6 period with respect to the phase of the 1st rectangular wave signal S1 are dinusoidal waves whose phase differs by 1/2 period. Thus, in adding the 1st and 2nd rectangular wave signals S1, S2, the 3rd harmonic components S13, S23 included in the 1st and 2nd rectangular wave signals S1, S2 are canceled together to cancel the harmonic components.

摘要： PURPOSE:To decrease the occurrence of white flaws and the occurrence of noise due to the dark current and obtain high picture quality by forming an electron blocking layer into a two-layer structure made of an As2Se3 layer and an Sb2S3 layer. CONSTITUTION:A photooonductive film 4 mainly made of amorphous silicon hydroxide and an electron blocking layer 5 formed into a two-layer structure made of an As2Se3 layer 6 and an Sb2S3 layer 7 are provided. The As2Se3 layer is excellent in an electron trapping function and properly traps an electron beam and prevents white flaws from occurring. The As2Se3 layer alone has an insufficient landing characteristic, and the Sb2S3 layer is provided to enrich the landing characteristic, thus the more excellent electron blocking layer is obtained. Thereby, the heat resistance is improved, the dark current exponentially increasing in relation to the temperature is controlled low, furthermore the electron strapping function of the electron blocking layer is reinforced, thus the occurrence of white flaws or noise is suppressed and the deterioration of the picture quality is suppressed.

摘要： PURPOSE:To reduce the cost. CONSTITUTION:A contact shoe 7 for receiving rotational force of a screw shaft is forded integrally with a head carriage 61. Consequently, since the contact shoe 70 is formed at the time of forming the head carriage 61, it is not necessary to fit the contact shoe 70 to the head carriage 61 at the time of assembling the head, and hence the number of fitting processes is reduced.

摘要： PURPOSE:To prevent the decreasing of a resolution even when a video signal is applied with multi-channel processing and a time base change is removed by separating the frequency component of a clock signal from the video signal in which a time base change is removed, limiting a level and decreasing it from the abovementioned video signal. CONSTITUTION:The device is equipped with a BPF 12 to separate the frequency component of a later-mentioned clock signal from a video signal OUT where a time base change is removed, a limiter 13 to limit the level of a separating output signal, and subtracting circuits 14 and 15 to subtract an output signal LIM from the limiter 13 from the above-mentioned video signal OUT1 by obtaining synchronization and send it as an output video signal OUT2. Using plural CCD elements multiphase processing is applied and the time base change is removed from an input video signal, a spurious signal component with the frequency of the clock signal supplied to the CCD elements as a center is included in the obtained video signal OUT1, and by the above-mentioned constitution, the output video signal OUT 2 can be obtained in which the spurious signal component is removed from the signal OUT 1.
