Title: System and method for detection and discrimination of plurality of signals
Inventor: MAIKERU II ROTSUKU
IPC: H04M1/50
Filed: 1993-06-24
Abstract: PURPOSE: To improve the talk-off performance of a telephone device like a voice store and forward device (VSF) by discriminating a signal consisting of two components having specific frequencies respectively and evaluating it at more than one quality level. CONSTITUTION: An analog input is sampled and supplied to a DTMF detection system. This signal is passed through a BPF 50 to minimize the effect of a finite transhybrid loss. Then in a receiver core 52 electric power of the input signal and a frequency component by a filter operation are measured. An output of the core 52 forms a sequential sampling set being an input to an evaluation algorithm 54. The algorithm 54 conducts prescribed tests of the respective sets, evaluates and transfers the sets, when being passed in all the tests, to a timing/ stability algorithm 56. The algorithm 56 determines the stability of the prescribed input over the set period, then transfers to an algorithm 58 and detects the beginning and the end of a DTMF signal to generate a single DTMF response.

Abstract: PURPOSE:To shorten the whole engine length by reducing the interval between the bores of two continuous cylinders which form a group and setting a suction port having a large amount of inhaled air onto the side where the bore interval is narrower, in each cylinder equipped with two suction ports. CONSTITUTION:As for four cylinders C1-C4 formed in a cylinder block in a 4- cylinder engine, the first and the second cylinders C1 and C2 and the third and the fourth cylinders C3 and C4 are respectively grouped, and the interval between the bores of the cylinders in each group is set narrower than that between the second and the third cylinders C2 and C3. In a cylinder head 3, the first and the second suction ports 6 and 7 and the first and the second exhaust ports 8 and 9 related to each combustion chamber 5 are formed. In this case, the first suction port 6 having a large amount of inhaled air in high-load and high-speed revolution is arranged on the narrower bore-interval side. Therefore, the cooling performance at the part having the narrower bore-interval is improved, and the whole engine length can be shortened.

Filed: 1989-06-16
Abstract: PURPOSE:To provide a sun sensor with accuracy and a processing time which are satisfactory over its entire measurement range by switching interpolation calculation and approximation calculation so that they can be processed by the processor mounted on an artificial satellite. CONSTITUTION:Deviations phi and theta in attitude angle are calculated by the linear approximation calculation when the output of a detection part and by the linear interpolation calculation when large by switching based upon threshold values. Namely, when the output of the detection part 3 exceeds neither of the threshold values 10 and 11, a switch 12 is switched to the output side of the result of an approximation calculation processing part 9, but when the deviations phiand theta in attitude angle from the sun are small, the detection part 3 is switched to approximate its outputs X and Y such as X=f(phi) and Y=g(theta). Further, the threshold values 10 and 11 are set outside the range the accuracy of the result of the interpolation calculation processing becomes inferior owing to a calculation error of a computer.

Filed: 1988-06-24
Abstract: PURPOSE:To enable correction of detection errors by arranging a pair of photocouplers in two sets at a different distance on a straight line orthogonal to a rotating shaft sandwiching a disc composing a detection signal generating section. CONSTITUTION:A motor 2 drives a detection signal generating section 1 directly to rotate having slits arranged at an equal interval concentrically perpendicular to a rotating shaft. With the rotation of the motor 2, light of light emitting elements 3 and 4 is interrupted with the slits to reach light receiving elements 5 and 6. Output pulse signals of the elements 5 and 6 are inputted into a microcomputer 10 after the cycle thereof is converted into a digital signal with counters 8 and 9. Based on data T1 and T2 of the counters 8 and 9, a rotational speed is determined by a computation without speed errors as caused by a deviation between the center of the signal generating section 1 and the center of a rotating shaft of the motor 2 to generate a current command for driving the motor 2. This command is inputted into a driver 11 to drive the motor 2.

Title: Quantitative analyzer for fraction pattern
Inventor: MAEDA OSAMI
IPC: G01N21/59
Filed: 1980-11-04
Abstract: PURPOSE:To eliminate the need for an operator to always watch and wait near an analyzer because there is no telling when a poor fraction occurs, by a method wherein a quantitative analysis of a large number of fraction patterns is continuously conducted. CONSTITUTION:A fraction confirming part 5 discriminates a fraction of a fraction factor computed at an operation part 2. If the fraction is proper, a recording part 6 prints and records each fraction factor and a concentration distribution chart on a recording paper, and if it is poor, a series of extinction degree data, indicating a concentration distribution of a fraction pattern, is stored in a data memory 4. A final discrimination part 7 discriminates the presence of a fraction pattern produced into a poor fraction. An extinction degree pattern produced into a poor fraction is transferred from a memory part 4 to a correction part 10, and an extinction degree distribution chart, produced into a poor fraction, and a quantitative analysis result are indicated in a monitor 9. An operator adds a fraction point to set a proper fraction point through the watching of the monitor 9. Based on the fraction point, the correction part 10 recomputes each fraction factor, and the result is printed and indicated in a recording part 6 together with an extinction degree distribution chart in which the fraction point is corrected.
