Abstract: A fuzzy inference device determines an inference operational quantity in accordance with inference rules each constituted by an antecedent and a consequent. An inference rule division determiner which receives data of input variables and output variables so as to determine the number of the inference rules. An antecedent neural element obtains a membership value corresponding to an antecedent of a specific inference rule from the divided data of the input variables and the output variables. A situational change processor adaptively determines an inference quantity of a consequent of each inference rule in the case of a change of an initial state or inference situations. An inference operational quantity determiner receives outputs from the antecedent neural element and the situational change processor and performs fuzzy inference in accordance with the inference rules so as to determine the inference operational quantity.

Abstract: An apparatus and method for automatically generating and adjusting fuzzy reasoning, i.e. logic, rules based on changes in the reasoning error. The apparatus includes a fuzzy reasoning section that performs fuzzy logic based on the fuzzy reasoning rules stored in the a rule memory. The parameters of the fuzzy reasoning rules are adjusted in a parameter tuning section based on the output of the fuzzy reasoning section and predetermined input and output data. A reasoning error calculation section calculates a reasoning error and a change in the reasoning error based on the results from the fuzzy reasoning section and the predetermined input and output data. The reasoning error calculation section also disables the parameter tuning section when the calculated reasoning error is less than a predetermined first threshold value.

Abstract: A fuzzy data processing device includes a data input portion for inputting data and first and second fuzzy regression model memories for storing first and second fuzzy regression models, respectively. In each fuzzy regression model, all coefficients are denoted as fuzzy values. A fitting degree calculator is provided to calculate a degree of fitting of the first fuzzy regression model to the second fuzzy regression model. A maximum detector detects the maximum of the calculated fitting degree. Thus, the estimated value (y*) is obtained at which the maximum degree of the fitting of fuzzy values Yx and Yz, i.e., the grade peak point of the overlapping portion, is observed.

Abstract: An inference conducted by use of fuzzy knowledge can be directly written in inference rules. It is possible to use ambiguous language expressions and freely describe flexible knowledge, although ambiguous, in a knowledge base. The user specifies execution priority orders or conviction degrees of inference rules such that even when an antecedent contains a confirmative or determinant action, a contention between rules is prevented. An intermediate results of a fuzzy inference is passed in a form of a real number or a fuzzy label to the next inference to achieve a fuzzy multi-stage inference. A multi-stage inference conducting a backtrack operation based on fuzzy knowledge is implemented to reflect a user's ambiguous knowledge.

Abstract: In a device for reproducing the information, especially the video signal optically, magnetically or otherwise recorded on the spiral or concentric track on a disk-shaped recording medium, a control system for controlling the radially inward or outward shift or jump of a reproduction transducer from one track to another for effecting, in addition to the normal reproduction, the special effect reproductions such as still picture, slow, fast and reverse motions. The control system comprising a shifting means for shifting or jumping the transducer in the radial directions substantially perpendicular to the tracks, a control means for maintaining the transducer to scan the desired track, and a detecting means for detecting whether or not the transducer has been shifted or jumped and brought to the desired track and generating the output signal in response to which the shifting means is disabled to decelerate and stop the shifting or jumping of the transducer.

Abstract: An optical reproducing device for reproducing still image signals recorded on circular tracks and moving image or audio signals recorded on spiral tracks on a disk. Concentric and spiral tracks may be intermingled on the same disk. The address signals for each concentric track or each coil of a spiral track are previously recorded. When the address signals are reproduced, they are processed so as to detect whether the readout address signals changes with time, thereby detecting whether the accessed track is concentric or spiral. An optical head drive system is controlled in a manner depending on whether the track is circular or spiral, so that an optical head can scan the desired concentric or spiral track.

Abstract: A tracking control system for a magnetic video recording and reproducing system, in which a signal is recorded on a magnetic tape as record tracks at an angle with respect to the longitudinal direction of the tape and is reproduced therefrom by rotary magnetic heads. At the time of start of playback, the relative phase of scanning tracks of the rotary heads and the afore-said record tracks is automatically varied at a predetermined cycle. During the period of this variation, a phase position at which a maximum value of the level of the reproduced signal from the rotary heads is detected, and the phase variation is stopped at the detected phase position so as to let the scanning tracks of the rotary heads coincide with the record tracks.

Abstract: A recorded signal reproducing system includes a signal generator circuit which produces a tracking control signal in response to an output from a detection circuit which detects that a difference between an output of a peak hold circuit which holds a maximum amplitude of an envelope of a reproduced signal from a rotary head for a relatively long period and an output of an envelope detection circuit exceeds a predetermined threshold. The tracking control signal is used to control the relative positional relationship between the rotary head and a magnetic tape for controlling tracking during the playback operation.
