Publication number: 20240095559Abstract: A steady range determination device (100) determines a steady range of a multilevel signal in operation data containing the multilevel signal. A conversion unit (122) converts the multilevel signal into at least one binary signal with using a threshold value. A prediction unit (123) inputs the binary signal converted by the conversion unit (122) to a prediction model (133) and calculates a converted binary signal prediction value. A range determination unit (126) calculates, based on the converted binary signal prediction value and the threshold value, a probability that a signal value of the multilevel signal contained in the operation data exists in a range determined based on the threshold value. The range determination unit (126) determines the steady range of the multilevel signal contained in the operation data, on a basis of the probability.Type: ApplicationFiled: November 30, 2023Publication date: March 21, 2024Applicant: Mitsubishi Electric CorporationInventors: Masaaki AOKI, Masahiko SHIBATA

Publication number: 20220342407Abstract: An irregularity detection apparatus (100) converts a multi-valued-signal value of each of one or more multi-valued-signals at each time point into a binary-signal-value group. The irregularity detection apparatus calculates a forecast-signal-value group at a subject time point by computing a forecast model with use of, as input, a past-signal-value group which is a collection of a binary-signal value of each of one or more binary signals at each past time point and the binary-signal-value group of each of the one or more multi-valued signals at each past time point. The irregularity detection apparatus compares with the forecast-signal-value group, a collection of the binary-signal value of each of the one or more binary signals at the subject time point and the binary-signal-value group of each of the one or more multi-valued signals at the subject time point, and determines a state of a subject system (220) at the subject time point.Type: ApplicationFiled: July 8, 2022Publication date: October 27, 2022Applicant: Mitsubishi Electric CorporationInventors: Masaaki AOKI, Masahiko SHIBATA

Patent number: 9828991Abstract: A variable displacement vane pump includes a notch portion which is a flow path provided to extend from an initiating end of a discharge port towards a terminating end side of a suction port. The notch portion is formed so that a sectional area of the flow path is smaller than a sectional area of the discharge port at the initiating end thereof and that a length of the flow path in a circumferential direction is 1.5 pitches or larger. The terminating end of the suction port is a point where the vane in the suction area last overlaps the suction port. The initiating end of the discharge port is a point where the vane departed from the suction area first overlaps the discharge port.
