Patent number: 9400198Abstract: In a flow sensor, an upstream heating element and a downstream heating element are disposed, respectively, upstream and downstream in a flow direction of a fluid so as to undergo mutual thermal interference. By controlling heating currents flown through the respective heating elements, an average temperature control portion maintains an average temperature of the two heating elements at a temperature predetermined degrees higher than a temperature of the fluid detected by a fluid temperature detection portion while a voltage ratio control portion performs control so that a temperature difference or a ratio of applied voltages between the two heating elements takes a predetermined value. A detection signal corresponding to a flow direction of the fluid is obtained from a state of the control on the heating currents and whether a flow direction of the fluid is forward or backward is determined.Type: GrantFiled: May 13, 2014Date of Patent: July 26, 2016Assignee: Mitsubishi Electric CorporationInventors: Kazuhiko Otsuka, Yuji Ariyoshi, Masahiro Kawai, Shinichiro Hidaka

Patent number: 9328686Abstract: A detection element portion is provided on an inner surface side of a plate as a wall surface portion defining a measurement passage in a flow measuring device. An intake-air temperature detection portion detecting a temperature of a fluid being measured is provided on one main surface of a substrate forming the detection element portion. A ventilation hole allowing a main passage in which the fluid being measured flows and the measurement passage to communicate is provided so as to penetrate through the plate. By achieving a state in which the substrate forming the detection element portion is installed so that an end thereof protrudes into the ventilation hole and a back surface of the end portion of the detection element portion where the intake-air temperature detection portion is formed is exposed toward the main passage, a response speed is enhanced.Type: GrantFiled: September 19, 2014Date of Patent: May 3, 2016Assignee: Mitsubishi Electric CorporationInventors: Masahiro Kawai, Naoki Morinaga, Kazuhiko Otsuka, Yuji Ariyoshi

Publication number: 20160097661Abstract: An environment sensor is mounted on a second surface of a circuit board that does not have a wire bonding pad, and is arranged in a measuring chamber that is disposed in a circuit board receiving portion. The measuring chamber has a communication port for communication with a main passage. According to this configuration, process addition attributable to integration between a flow rate measurement device and the environment sensor is not required. The environment sensor does not affect air flow in a bypass passage, and thus detection accuracy of a flow rate detection element that is arranged in the bypass passage does not decline.Type: ApplicationFiled: January 16, 2015Publication date: April 7, 2016Applicant: Mitsubishi Electric CorporationInventors: Shinichiro HIDAKA, Yuji ARIYOSHI, Masahiro KAWAI, Kazuhiko OTSUKA, Naoyuki KISHIKAWA, Naoki MORINAGA

Patent number: 9234817Abstract: Dust with various particle diameters entering a bypass passage, particularly, relatively large dust with a particle diameter of 100 to 200 ?m or so, is reliably caused to collide with a first step-shaped part, a second step-shaped part and a plate-like member to be sufficiently decelerated and reach a flow rate detecting device with low collision energy. This can prevent the flow rate detecting device from being damaged by collision of dust. Furthermore, the placement position of the plate-like member is optimized to suppress air turbulence at a flow rate detecting part, which achieves a good balance between flow rate detection accuracy and dust tolerance.Type: GrantFiled: February 14, 2014Date of Patent: January 12, 2016Assignee: Mitsubishi Electric CorporationInventors: Naoyuki Kishikawa, Yuji Ariyoshi, Masahiro Kawai, Hiroyuki Uramachi, Kazuto Akagi
