Patent JP-H06188749-A (JP)
Title: Adaptive viterbi detector
Inventor: KAHLMAN JOSEPHUS ARNOLDUS H
IPC: H04L25/30
Filed: 1993-06-30
Abstract: PURPOSE: To eliminate the need for fixing the amplitude of a detection signal at a specific level for the proper operation of a data receiver by setting the magnitute of a vertical coordinate interval in proportion to the estimate of amplitude of the detection signal. CONSTITUTION: Two remainders of signals m<+> , m<0> and m<-> are stored in the shift registers 20 and 22, respectively. The register 20 stores the survivor where the estimate ΛaK of a signal aK has logical value -1 at the nearest time point, and the register 22 stores the remainder where the estimate ΛaK of the signal aK has logical value 1 at the nearest time point. When the signal m<0> is active, the outputs of two OR gates 24 and 26 are also active. At the same time, the control inputs SH of both registers 20 and 22 are activated. Then the logical value of input signals of both registers 20 and 22 are shifted to another relative shift register. This means that those two remainders are expanded to the signals which are set at the nearest time point but equal to a single signal.

Inventor: MATSUOKA KOICHI
IPC: H02P27/08
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To stabilize a current control system, while minimizing the flux current even when the output voltage of an inverter approaches a maximum level by receiving the magnitude and the angle of a voltage vector and the sum of a torque angle correction value and a permanent magnet flux angle and delivering a polyphase PWM voltage command to an inverter. SOLUTION: A PWM voltage generating section 17 receives the magnitude and the angle of a voltage vector, outputted from a voltage vector magnitude limiting section 14, and the sum of a torque angle correction value and a permanent magnet flux angle and delivering a polyphase PWM voltage command to an inverter INV. When the magnitude of the voltage vector exceeds the maximum level of inverter output, the voltage vector is fixed, a weakening flux density is minimized and high speed torque control performance required for idling control can be ensured by torque angle control. Consequently, the current control system can be stabilized, while enhancing the efficiency.

Filed: 1981-10-14
Abstract: PURPOSE:To improve the corrosion resistance of an Fe-Al-Si alloy without deteriorating the superior magnetic characteristics by combinedly adding a Pt group element and Pb to the Fe-Al-Si alloy. CONSTITUTION:This alloy consists of, by weight, 3-16% Si, 2.5-17% Al, 0.001-4.0% of >=1 kind of Pt group element, 0.01-3.0% Pb and the balance chiefly Fe.

By this method the wear resistance and machinability can be also improved. By further adding an adequate amount of an element such as Ti or V as a secondary component, the corrosion resistance can be improved furthermore by the synergistic effect.

Abstract: PURPOSE:To easily produce a postcard with photograph in a processing laboratory or the like without a complicated adhesive applying process or a laminating device by a method wherein a rear surface of a postcard and a rear surface of developed phographic paper are thermally bonded to each other through a thermally active adhesive layer previously applied to the rear surface of the photographic paper by extrusion coating and specified in melt flow rate. CONSTITUTION:A thermally active adhesive layer in use is provided by extrusion coating using an adhesive having an MFR value of 0.7-100g/10min, pref. 1-80g/10min, in accordance with JIS-K7210. An adhesive having an MFR value not more than 0.7g/10min is hardly applied by extrusion coating because of its high viscosity. On the contrary, an adhesive having an MFR value not less than 100g/10min cannot be stably applied at a high speed by extrusion coating. Furthermore, it has high loadings of a low-molecular component, such as a wax, in composition, thus having possibility of bleeding on a surface of a postcard or a surface of photographic paper. In addition, a possibility of generating an interlaminar release at an adhesive layer between a postcard C and photographic paper A is raised at a summer high temperature (40-60 deg.C).
