Title: Learning controller for time series information signal
Inventor: TAKAKUWA AKIO
IPC: G06N3/08
Filed: 1989-02-14
Abstract: PURPOSE:To spontaneously form one recognition pattern by feeding the output signals of plural neurons included in an intermediate layer back to the same neuron and leading out a signal showing the update value of the synapse connection by learning as the output signal of a negative feedback amplifier. CONSTITUTION:A self-feedback is formed to each of neurons 56i, 58i, 62j, 64j and 66k included in an intermediate layer of a neural network excluding the input and output layers. Then the negative feedback amplifiers 24 and 26 apply the allocation between the weight applied to the feedback of the past time series information signal and the weight applied to the present time series signal. Thus the learning and the storage are carried out. Thus the desired value equal to the value of a teacher information signal S27, for example is gradually obtained via the full time series information signals S21/S21a and S22/S22a. That is, one recognition pattern is spontaneously obtained.

Title: Supersonic signal detection of displacement detector
Inventor: KYOIZUMI KOZO
IPC: G01D5/48
Filed: 1985-02-23
Abstract: PURPOSE:To enable detection without an error of a supersonic signal even for a condition of pronounced disturbance, differentiating a supersonic signal detected in the specified position, and measuring propagation time of the supersonic wave at the crest of the supersonic wave generated by magnetostriction. CONSTITUTION:When input voltage of a differential circuit 9 is lower than that applied to the positive input, an output H is generated from a voltage comparator 12. Further, when an output voltage of a high-pass filter 7 is hither than that applied to the negative input, an output F is generated from a voltage comparator 18. As these outputs F, H of the comparators 8, 12 are applied to an AND element 13, a pulse signal I is issued only when signals F, H are placed in ON position simultaneously. By measurement of time from the start of an electric pulse to the rise-up time of the pulse signal I, the arrival time at the crest of the supersonic wave propagated through a magnetostriction line can accurately be determined.

Abstract: PROBLEM TO BE SOLVED: To suppress flapping at the reverse rotation and to obtain a sufficient cleaning effect by setting the height of a rib for pressing a cleaning sheet to the disk higher on the outer peripheral part side than on the inner peripheral part side. SOLUTION: The rib 11 is so formed that the height in its inner peripheral part side, defined as h1, and the height on its outer peripheral part side, fined as h2, attain h1<h2, i.e., the outer peripheral part side is higher. The outer peripheral part side of the disk is liable to flap at the time of high-speed rotation of the disk, but this flapping may be effectively suppressed by making the height on the outer peripheral part side of the rib 11 higher. A suitable number of grooves are formed mainly on the outer peripheral part side of the front surface of the rib 11. The shielding of the flow of the air generated accompanying the rotation of the disk may be prevented by the presence of these grooves. Namely, the air may be made to escape by the grooves and the stability at the time of the high-speed rotation of the disk may be maintained.
