Title: Receiver estimating maximum likelihood series
Inventor: ONO SHIGERU
IPC: H04L27/22
Filed: 1992-04-16
Abstract: PURPOSE:To improve the reception characteristic with less processing quantity. CONSTITUTION:The receiver is provided with a transversal matching filter 5, a transmission line estimate circuit 9 estimating an impulse response of a transmission line, and a state estimate circuit 6 estimating a transmission symbol series from an output of the matching filter 5 based on the estimated impulse response. Then the transmission line estimate circuit 9 sets a time interval to the estimated impulse response so that a largest sample points in the order of the amplitude from a sample point having the maximum amplitude corresponding to a tap number of the matching filter 5, sets a tap coefficient based on only the sample points in the time interval and estimates a transmission symbol series. The optimum impulse response of the transmission line whose length is NT is estimated by implementing the amplitude comparison of the signals without calculation of a square sum of the amplitude of the signals.

Abstract: PURPOSE:To make it possible to perform highly accurate measurement by inputting light rays in the required direction into the preform of optical fiber and cylindrical glass for rod lenses, picking up the image-output projecting light, linearly approximating the spot shape, determining an output angle, and measuring the distribution of refractions. CONSTITUTION:In a preform 1, the distribution of refractive indexes is changed in the radial direction on a stage. Incident light 41 is projected in the direction orthogonal to a central axis 2 of the preform 1. Images 30 - 32 of scattering projected light rays are formed on a projection plane Q. The images are picked up with a TV camera 10. The data of the image picked-up positions are binary-coded in an operating means 13. The data are linearly approximated by a least square method and the like, and a straight line 20 is determined. Coordinates Xc of an intersection (c) between an X axis on a plane P and the straight line 20 are determined with a position computing means 14. The plane P is orthogonal to the axis 2 including the incident light 41. An output angle phi is determined highly accurately based on the data of many positions. A stage is moved, and the output angle phi at each radial position of the preform 1 is obtained by the same way. The distribution of the refractive indexes can be measured highly accurately based on the highly accurate output angles by a refractive-index-distribution operating means 16.

IPC: G01C21/00
Filed: 1995-04-21
Abstract: PURPOSE: To properly correct a distance coefficient used for seeking a travel distance. CONSTITUTION: A microprocessor 214 seeks a vehicle travel distance in multiplying a distance coefficient to the count number made up of factoring a pulse number to be outputted by a car speed sensor 20 with a counter 216. In addition, a current position on a road is estimated from map data read out of a CD-read- only memory 205 via a driver 206, each of measured data of an angular velocity sensor 201, an azimuthal sensor 202 obtained via two analog-to-digital converters 209, 210, and a travel distance of the sought vehicle distance. In succession, the distance coefficient is dynamically corrected according to a difference between a travel state in case of having the estimated current position suited and another travel state shown by measured data of respective sensors.  When the estimated current position skips to a position being not continuous and it is bent as far as almost 90 degrees at an intersection or the like, however, the compensation so far applied to the distance coefficient is canceled, and this distance coefficient is corrected by the value having considered the degree of reliability in the correction applied in the past, anew.

Abstract: PURPOSE:To form a thin film in excellent film thickness controllability and crystallinity by a method wherein the thin film is grown through the intermediary of a thin film in even liquid state not to ball up on an insulating matter or a semiconductor substrate in the initial growing period. CONSTITUTION:A substrate is heated by an infrared ray lamp to form a GaAs film (LPE film). At this time, Ga in about several molecular layers evenly adheres to a GaAs substrate and then TEG, AsH3 gas about one molecular layer amount are alternately led to be grown through the intermediary of Ga (liquid) in the moleclular layer. The leading-in pressure of TEG may extend over broad range from several Torr to 10<->10Torr if only the led-in amount of one molecular layer can be controlled. The substrate temperature of Ga even in several layers can be 500 deg.C not to ball up. Furthermore, the leading-in pressure, leading-in time and the disposal time of AsH3 may be allowable if only the growth of about one molecular layer can be controlled since the LPE film is grown while observing the reflected light intensity.

Abstract: PURPOSE: To eliminate the luminance slope on the projection screen by giving the vertical and horizontal modulation to the luminance of the picture of the TV picture receiver in case the picture on the picture receiver is magnified on the screen.  
     CONSTITUTION: The double integration is given via integrating circuit 13 to the horizontal flyback pulse sent from horizontal deflecting circuit 11. And the parabola signal of the horizontal cycle is formed as the output signal to be compounded at compounding circuit 14 with the parabola signal of the vertical cycle produced in the same way as the horizontal cycle parabola signal. The compound signal is then supplied to luminance control circuit 8 to give the luminance modulation to the video signal. The luminance modulation is carried out in order to correct the luminance slope on projection screen 4. In other words, the modulation is applied to secure higher brightness at the periphery of circuit 8 to prevent screen 4 from becoming darker toward its circumference area. A sufficient correction is possible through the correction of only one of the horizontal and vertical directions according to the state of the luminance slope.

Filed: 1987-04-20
Abstract: PURPOSE:To prevent a plating film of Cu or the like from being separated from a ceramic substrate, by a method wherein a common electrode is formed on a ceramic substrate on which no glaze layer is formed and thereby, the glaze layer is subjected to cracking by adding a force to the glaze layer due to the difference in thermal expansion coefficient. CONSTITUTION:A glaze layer 2 is printed to be baked on an area other than that processed by Cu plating in the formation of a common electrode 5, and the common electrode 5 is formed on a ceramic substrate 1 via a conductive layer 4 and a resistor layer 3 by Cu plating. Then, since the conductive layer 4 formed on the glaze layer 2 is good in flatness, it can be easily worked and formed in a fine pattern. Thus by forming a plating film of Cu or the like as the common electrode on a part without glaze on the ceramic substrate, a thermal head of good reliability in which peeling off of a plating film of Cu or the like is not generated, can be formed.
