An apparatus for regenerating original signals comprising: means for introducing a first signal that is produced as an original signal passes through a system that cuts off predetermined frequencies; a first circuit means which produces a third signal obtained on an open loop responsive to said first signal and a second signal which is regenerated from a signal of a predetermined frequency that is cut off by said system; and a second circuit means which regenerates the original signal by converting said third signal into a binary signal.

An improved 8-8 mpping table system in digitally and magnetically recording video signals. Video signals coded into natural binary codes consisting of 8 bits are converted into different binary codes consisting of 8 bits constituted by patterns in which a continuous number of the 1's or the 0's does not exceed a predetermined number. In these codes, the continuous number of the 1's or the 0's is so limited that a maximum magnetization interval is reduced in magnetically recording the signals. Therefore, erroneous code is prevented from occurring in reproducing the signals.

Disclosed is an apparatus in which a picture signal is converted into digital signals and the digital signals are recorded into a recording medium, and which is suitable to perform dubbing of the digital signals reproduced from the recording medium. The apparatus employs the component method in which a luminance signal and chrominance signals constituting a picture signal are recorded separately from each other. According to the component method, the sampling frequency of the chrominance signal is set to be about 1/3-1/4 of that of the luminance signal, and therefore the recording/reproducing of a picture signal is carried out after the bit rate of the digital luminance signal is converted into a value equal to the bit rate of the digital chrominance signal. When digital dubbing is carried out between two apparatus each employing the component method, the taking-in and taking-out of signals to be dubbed are performed with respect to the digital luminance signals and digital chrominance signals having the same bit rate with each other.
摘要:
A digital recording and reproducing system wherein luminance signals digitized and converted into the low speed signals and chrominance signals digitized at the time of recording are distributed among a plural number of channels and the signals of the plural number of channels are recorded respectively on a recording medium. At the time of the reproduction, the signals of the plural number of the channels are reproduced respectively from the recording medium and combined to form the luminance signals and the chrominance signals respectively. The luminance signals in the combined signal are converted into a high speed signal and output terminals for outputting dubbing signals from the system for dubbing the signals are led. The output side of a low speed-to-high speed converter and a channel combination circuit.

A diagnosis device for diagnosing loosening of a stator core of a rotary electrical machine. The diagnosis device has: excitation means for vibrating the stator core in the radial direction; vibration detection means for detecting the vibration of the stator core in the radial direction; means for frequency-analyzing an output signal of the vibration detection means that detects vibration generated in the stator core when the stator core is vibrated by the excitation means so as to extract a measurement natural vibration mode of the stator core in a circular ring natural vibration mode; means for estimating a circular ring natural vibration mode of the stator core from shape data of the stator core; and means for determining a clamping state of the stator core by comparing the measurement natural vibration mode and a determination criterion obtained based on the estimated natural vibration mode.

An optical media converter system is divided into an outdoor installed optical media converter and an indoor installed unit, which are connected to each other through an electrical Ethernet cable. The indoor installed unit includes two electrical Ethernet terminations and a power source section for supplying an electrical power from indoor to outdoor. The outdoor installed optical media converter includes an optical-electric converter, optical Ethernet termination, electrical Ethernet termination, and a power source section for generating a power source by an electrical power supplied from the indoor. With the above configuration, there can be provided an optical media converter system in which the need to draw the fiber-optic cable into a home can be eliminated, cost involved in a wiring work can be reduced, and a circuit design thereof is advantageous in cost reduction.

A laser beam 21 outputted by a laser oscillator 3 is collected by a machining head 4, so that the surface of a roller 2 is irradiated with the laser beam. An encoder 5c outputs a signal in accordance with a rotational position of the roller 2. A control portion 24 controls the laser oscillator 3 to irradiate the roller 2 at the same spots on the surface with the laser beam 21 per rotation of the roller 2, the irradiation being repeated a plurality of times, thereby forming recesses in the surface of the roller.

In order to improve the rapidity with which an automatic equalizer can be pulled in when transmitting data at high baud rates, each of the modems of secondary stations are arranged to detect the divergence of the automatic equalizer included therein and induce the issuance of a tone signal which is supplied to the primary station and induces the latter to reissue a training signal. The automatic equalizers in the secondary stations pull in on the training signal which ceases to be issued when the tone signal is no longer generated.
