Title: Correcting method for error in measured speed of resolver
Inventor: SOMA SHINJI
IPC: G01P3/44
Filed: 1990-11-30
Abstract: PURPOSE:To make it possible to detect the accurate rotating speed all the time by rotating a resolver at an equal speed and obtaining a speed correcting coefficient before the resolver is actually used. CONSTITUTION:At first a resolver 50 is driven at an equal speed omega. The rotating speed omegan is sampled in response to each rotating position thetan. Then, the ratios between the obtained omega1,...omegan and omegamax and the preset equal speed omega are obtained. Correcting coefficients A(theta1),...A(thetan) and A(thetamax) corresponding to the positions theta1,...thetan and thetamax are obtained. Then, the resolver is actually driven. A CPU 70 measures the rotating position R(thetan) by signal processing. The rotating speed V(thetan) is obtained by computing the difference between the data at this position and the data at the previous position. The CPU 70 corrects the rotating speed V(thetan) by using the correcting coefficient A(thetan) for the rotating position R(thetan). The corrected value is made to be the true rotating speed Vc(thetan), and the speed is used for actual control. Thus the accurate rotating speed can be always detected.

IPC: G06F12/02
Filed: 1989-12-21
Abstract: PURPOSE:To eliminate a memory for generating an address by generating a read address of an equal speed call memory while being split into a high-order read counter and a low-order read counter. CONSTITUTION:A signal series conversion circuit consists of an equi-speed readout memory (RAM) 1 to write a signal string, a write counter 2 generating a write address at that time, a high-order read counter 3 and a low-order read counter 4 generating a read address to read a written signal string. The high- order read counter 3 inputs a read clock pulse and a read frame pulse and outputs counts 0-3 for each 4-bit to the equi-speed call memory 1 as a high-order read address and outputs one clock pulse to the low-orer read counter 4. Thus, the low-order read counter 4 advances the count for each 4-bit and outputs the result to the equi-speed call memory 1 as a high-order read address.

Title: Delection of raman effect with modulation of polarized wave
Inventor: BLONDEL JEAN-PIERRE
IPC: H04B10/532
Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To increase power in a link provided with no repeater by providing polarized scramble means for scrambling the deflection of an inputted light wave. SOLUTION: The polarized scramble means is provided for scrambling the deflection of the inputted light wave. For the example of a figure, the scramble means is composed of a polarized scramble for rotating the polarization of signal of 1555 nm with a high frequency. In the case of the figure, the signal inputted with the wavelength of 1555 nm is converted to the noise of about 1650 nm by a Raman effect. In the figure, it is recognized that the wavelength power of signal of about 1555 nm in respect to the same noise level of about 1650 nm is higher than power not to scramble the polarized wave for about 3dB in the case of this system. Thus, the power higher than ordinarily used power can be inputted to an optical fiber transmission system provided with no repeater.
