Filed: 1982-12-27
Abstract: PURPOSE:To attain a small-size and light weight further reduce cost, of a device by combining one polarizer with a magnetooptic element which provides polarization on a slanting surface arranged at the complementary angle of a Brewster angle to an optical axis. CONSTITUTION:Light L12 reflected by an end surface of an optical fiber 5 passes through the polarizer 1 in the opposite direction as shown by B to enter the transmission surface 13 of the magnetooptic element 10. The light is influenced therein by an external magnetic field H and its plane of polarization rotates counterclockwise in regard to its optical axis; and the light propagates while reflected repeatedly by a reflecting film 14. Linear polarized light reaching the slanting surface 12 while the plane of polarization rotates by 45 deg. has the plane of polarization rotated by 90 deg. as compared with light in the forward direction shown by A and is reflected by the slanting surface 12 which provides polarization, so almost no light returns to a semiconductor laser 4. This constitution reduces the size, weight and cost of the optical isolator.

Filed: 1993-09-14
Abstract: PURPOSE:To detect the rotational position and the rotational speed of a motor witch high accuracy without installing a sensor used to detect the rotational position and the rotational speed of the motor in a motor driving gear. CONSTITUTION:On the basis of a voltage which is applied to a motor 1 and of a motor current which flows through the motor 1, the rotational speed of the motor is estimated, the estimated value of the rotational speed of the motor is integrated, and the estimated value of the rotational position of the motor is found. Then, a position which is computed on the basis of the output value of a motor rotation sensor 9 is interpolated by the estimated value of the rotational position of the motor. Thereby, even when the motor rotation sensor 9 with a low resolution of one pulse/revolution is used, the rotational position and the rotational speed of the motor can be detected with high accuracy. In addition, since the motor rotation sensor whose resolution is low is sufficient, the cost of the driving gear can be reduced.

Abstract: PURPOSE:To shorten a calling subscriber's waiting time and to reduce the load on a receiving subscriber and an automatic private branch exchange. CONSTITUTION:The number of delayed calls, an average waiting time of terminating calls and a time-patterned blocking time are inputted from a computer terminal 4 and registered in an external computer 3. The termination waiting state information of main line trunks 30 to 32 is informed from a CPU 22 to the computer 3. When automatic terminating call distributing receiving boards 1, 2 are turned to idle states and answer the trunks 30 to 32, the information also is informed to the computer 3 and the termination waiting time is stored. The computer 3 detects the number of waiting terminating calls and the average waiting time, compares the average waiting time with a set blocking time, and when the average waiting time is equal or more to the set value or coincides with a prescribed time for a time pattern, outputs a command for blocking the trunks 30 to 32 to the CPU 22. The CPU 22 catches one of the trunks 30 to 32 to set up a terminating call to a calling state. When the average waiting time is less than the set blocking time, the computer 3 commands the CPU 22 to restore the trunks 30 to 32.

Filed: 1992-08-28
Abstract: PURPOSE:To efficiently select a neural network and to execute learning by selecting the optimum value of the number of elements in an intermediate layer based on calculation output in preliminary learning and an error obtained from teacher data. CONSTITUTION:The number H of the elements in the intermediate layer 12 are set to be arbitrary numbers m (m>=1), (m+1), (m+2)...(m+n) and the number H of the elements in the intermediate layer is changed. A result obtained by learning the respective numbers by the prescribed number of times (N1) and by calculating the respective errors Er is shown. When the number of learning times (N1) is sufficiently large, calculation output comparatively rapidly approaches teacher data and the error Er is considerably reduced as shown in a curve line '1' in the neural network using an appropriate number as the number H of the elements in the intermediate layer 12. In the case of the neural network where a selected number is unsuitable for the number H of the elements in the intermediate layer 12, calculation output does not easily approach teacher data and the error Er is small in a reduction rate as shown in a curve 2 or a curve 3.
