摘要： PROBLEM TO BE SOLVED: To provide an echo canceler device capable of suppressing the occurrence of echoes by preventing a transient action even when a sneak path with an echo canceler connected thereto is interrupted. SOLUTION: This echo canceler device is provided with an echo canceler circuit for reducing the sneak-path amount to a four-line side transmission path of an echo signal by controlling a false echo signal so as to make an error signal obtained by reducing an input signal to be zero. The echo canceler device controls so that, when a silence detecting part 1 detects the interruption of the input signal, an output from the four-line transmission path is made to be in a silent output state, and an echo canceler 4 is made to hold an adaptive filter coefficient of an adaptive filter just before the interruption of the input signal, and when the interruption of the input signal is released, the silent output state of the four-line transmission line is released, and the adaptive filter of the echo canceler 4 performs control for releasing the holding of the adaptive filter coefficient.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for periodic signal detection by which a machine signal whose amplitude changes extremely periodically at a period similar to a burst-interval of voice like a ringing tone similar to 100% modulation is distinguished from voice by using the fact that the machine signal always has periodicity although autocorrelation property in the voice does not have a fixed period. SOLUTION: Burst continuity of an input signal is judged by power measurement of the input signal, in the case it is judged that the input signal has the burst continuity and an autocorrelation function has periodicity, when judging that the period of the input signal is the period of the specific target periodic signal, the input signal is judged as the periodic signal having the specific period.

摘要： PURPOSE:To make it possible to perform the optoelectronic transducing operation of a solid-state image sensing element without the effect of the voltage of an electron-beam generating means by providing a transparent conductor film between an optical fiber plate and the solid-state image sensing element. CONSTITUTION:An optical fiber plate 13 is brought into close contact with a fluorescent plane 12 on which an electron beam is projected. A solid-state image sensing element 26 is brought into close contact or close to the plate 13. A transparent conductor film 25 is provided between the output end surface of the plate 13 and the light receiving surface of the element 26. Said conductor film 25 blocks the non-uniform charging of the output end surface of the plate 13 and electrostatically shields the element 26 from an electron gun 7. Therefore, recording of data or transducing operation into electric signals can be achieved through the element 26 at low noises, and a starry sky phenomenon is reduced.

摘要： PROBLEM TO BE SOLVED: To form a color image having high quality by using nonmagnetic toner which does not incorporate magnetic powder while writing a magnetic latent image on a magnetic recording medium by a magnetic recording head. SOLUTION: The magnetic latent image is firstly formed only in an area corresponding to the achromatic part (non-image part) of the magnetic recording medium 1 by a magnetic head 2. Then, particles containing the magnetic powder 5 in a developing device for the particles containing the magnetic powder 3 are used for developing in the area where the magnetic latent image of the magnetic recording medium 1 is formed through a magnetic roller for developing the particles containing the magnetic powder 4. The nonmagnetic toner 7 in a nonmagnetic toner developing device 6 is used for developing in the area corresponding to the achromatic part and that corresponding to the chromatic area of the magnetic recording medium 1. The particles containing the magnetic powder 5 and the nonmagnetic toner 7 of the area corresponding to the achromatic part of the magnetic recording medium 1 are removed, and the nonmagnetic toner 7 of the area corresponding to the chromatic part is transferred to a transfer medium 10, so that the nonmagnetic toner 7 on the transfer medium 10 is fixed on the transfer medium 10.

摘要： PURPOSE: To make it possible to distinctly record high-quality image information with less fogging by setting the gap width near the edges in the axial direction of the stripes of a magnetic recording head narrower than a central gap width. CONSTITUTION: The width(s) of the stripe of the magnetic recording head corresponds to the recording width of a sub-scanning direction (y direction). The gap width of a magnetic core 1 is changed in a sub-scanning direction and the gap width(g') near the edges is set smaller than the gap width G' on the central side. As a result, magnetic fields are concentrated more toward the edge sides than the central side and, therefore, the magnetic fields of the recording surface are made larger on the edge sides than on the central sides. Then, the magnetic latent image having peaks at the parts of the edges is easily obtd. on a magnetic recording medium. Consequently, the sharp magnetic latent image even near the edges in the transverse direction of the stripe of the magnetic recording head is recorded.
