Patent number: 10347068Abstract: A capacitance detection device includes a first electrode and a second electrode that at least partially face each other on opposite sides of a transfer path. An oscillator circuit forms an electric field between the first electrode and the second electrode. A detection circuit detects a change in capacitance between the first electrode and the second electrode. At least one of the oscillator circuit and the detection circuit is included in each of a first board and a second board. The first board is disposed such that a side surface of the first board faces the first electrode in an electric field direction, and the second board is disposed such that a side surface of the second board faces the second electrode in the electric field direction.Type: GrantFiled: September 25, 2017Date of Patent: July 9, 2019Assignee: Mitsubishi Electric CorporationInventors: Miki Kagano, Hiroshi Araki, Toshiaki Shoji, Hideki Matsui, Kazuya Makabe, Tomoyuki Miyata, Tomokazu Ogomi

Patent number: 9664533Abstract: A magnetic field generator disposed on one surface side of a sheet-shaped object-to-be-detected contains a magnetic component. The magnetic field generator includes a first magnetic pole part that forms a first magnetic pole, and a second magnetic pole part that forms a second magnetic pole with reverse polarity of the first magnetic pole. The magnetic field generator generates a cross magnetic field that crosses the object-to-be-detected. An MR element is disposed between the first magnetic pole part and the object-to-be-detected. The resistance value of the MR element changes according to a change in a component of the cross magnetic field in a conveying direction. The position of the MR element in the conveying direction is position shifted along the conveying direction from the center position of the first magnetic pole part in the conveying direction, and located between both ends of the first magnetic pole part in the conveying direction.Type: GrantFiled: February 5, 2014Date of Patent: May 30, 2017Assignee: Mitsubishi Electric CorporationInventors: Hiroyuki Asano, Toshiaki Shoji, Tomokazu Ogomi, Kenji Shimohata, Masaaki Okada, Miki Kagano, Masashi Hino, Hideki Matsui

Patent number: 9407217Abstract: When a switch is set to off, and a switch is set to on, the voltage of a SigOut terminal is stabilized with a reference voltage, and a bias voltage is applied to a capacitor. Changing the switch from on to off, with the bias voltage retained in the capacitor, a detection signal which is input via a SigIn terminal is amplified with the reference voltage as a reference, and an amplified signal is output from the SigOut terminal.Type: GrantFiled: June 12, 2012Date of Patent: August 2, 2016Assignee: Mitsubishi Electric CorporationInventors: Miki Kagano, Kazuya Makabe, Tomokazu Ogomi, Takahito Nakanishi, Tadashi Minobe, Takashi Ito

Patent number: 9244135Abstract: A magnetic sensor device includes a first magnet and a second magnet that are disposed on mutually opposing sides of a conveyance path, and one of poles of the first magnet faces an opposite pole of the second magnet. The first magnet and the second magnet generate a cross magnetic field whose strength in a spacing direction, which is orthogonal to a conveying direction, is within a predetermined range. An AMR element is located in a magnetic field in which the strength of the cross magnetic field in the spacing direction is within a predetermined range, and detects, as change in a resistance value, change in the cross magnetic field caused by an object to be detected. A multilayer board outputs the change in the resistance value detected by the AMR element to a processing circuit.Type: GrantFiled: May 11, 2012Date of Patent: January 26, 2016Assignee: Mitsubishi Electric CorporationInventors: Tomokazu Ogomi, Hiroyuki Asano, Toshiaki Shoji, Takeshi Musha, Jin Inoue, Masaaki Okada, Miki Kagano, Kazuya Makabe, Kenji Shimohata, Takeshi Kishimoto
