摘要: A frequency divider wherein the pulse input having been delayed by a predetermined time interval is impressed upon a plurality of cascade connected flip-flops, and the output from each of the flip-flops is fed to an AND gate to which is also fed the input which has not passed through the delay circuit to produce a resultant AND output to be fed back to each of the required flipflops, thereby increasing the upper limit of the frequency to be divided and practically eliminating the danger of a malfunction in the system.

摘要: An adaptive logic circuit which is a basic component circuit of a learning machine. A voltage divider comprising a variety of parallel resistances and a common resistance connected in series thereto gives weighting constants one of which is to be selected by applying outputs of respective stages of a shift register to the gates of MOS field effect transistors connected between the respective resistances and the common resistance. The MOS field effect transistor whose control terminal is supplied with an input signal becomes conductive thereby providing a threshold function. This circuit can be formed entirely of solid state elements, enabling the electronic setting of weights so that the learning processes can be performed at very high speed.

摘要: An Esaki diode and a high-conduction diode are connected in parallel across the base-collector junction of a transistor junction of a transistor to constitute a logic circuit. The input-output curve of this transistor shows a hysteresis characteristic and the transition of the output state can be done in a very short time with stable operation. Connection of a plurality of such logic circuits in a ring provides a frequency divider circuit operating at a high speed. Combination of a plurality of such logic circuits with delay elements constitutes an astable, monostable, bistable multivibrator or other highspeed logic circuit.

摘要: A learning device having a plurality of magnetic cores which serve as multistage level weight memory elements. In the device, the product of an input and a corresponding weight is delivered from the magnetic core in the form of a digital output, and the sum of digital outputs is compared with a threshold value in a decision circuit to derive an error signal so that the weight carried by each magnetic core can fully automatically be corrected until the actual output coincides with an expected output.

摘要: One of the greatest problems tending to occur in an attempt to effect speech recognition with a speech recognition apparatus is that individual difference is present in the speech frequency distribution. Obviously, the apparatus fails to recognize a speech correctly which can naturally be recognized by the human being, if there is such individual difference. This specification discloses an apparatus wherein individual difference is eliminated from the frequency to time pattern to normalize such pattern in an attempt to effect speech recognition, thereby making it possible to achieve accurate speech recognition.

摘要: An automatic tuner for television receivers in which the oscillation frequency of a first voltage controlled oscillator in a phase locked loop is brought to a predetermined frequency corresponding to given channel selection information, and the oscillation frequency of a second voltage controlled oscillator is swept until the beat frequency obtained from the first and second voltage controlled oscillators reaches a particular frequency. After the reaching of the practicular frequency, the second voltage controlled oscillator is locked to its oscillation frequency at the instant of reaching the particular frequency, and its output is used as a local oscillator signal.

摘要: A learning machine in which threshold values corresponding to the desired output conditions and having a dead zone therebetween are used during the learning process for the discrimination of the output from a memory storing a plurality of standard pattern information, and this discriminating faculty is utilized for the discrimination of input pattern information with respect to a single threshold value having no dead zone. Thus, the precision of discrimination can be remarkably improved due to the fact that the threshold values having a dead zone are used during the learning process, and the learning can be digitally and automatically carried out.
