Patent number: 9506794Abstract: A flow rate measuring device includes: a bypass passage; a flow rate detecting element; and a flow rate measuring circuit. The bypass passage includes: an inflow port; an outflow port; and a plurality of bent portions. The plurality of bent portions include first to third bent portions for forming U-shapes, and a fourth bent portion for bending the bypass passage bent at the third bent portion so as to be parallel to a mainstream flowing direction. The flow rate detecting element is arranged inside the bypass passage in a part after bending at the fourth bent portion. A route connecting the inflow port and the flow rate detecting element as a straight line is blocked by an inner wall surface of the bypass passage on an outer peripheral side, which is formed between the first bent portion and the second bent portion.Type: GrantFiled: April 27, 2015Date of Patent: November 29, 2016Assignee: Mitsubishi Electric CorporationInventors: Kazuto Akagi, Naoyuki Kishikawa, Hiroyuki Uramachi, Hiroshi Sakanoue, Masahiro Kawai, Yuji Ariyoshi

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

Patent number: 8220326Abstract: Although flow detection accuracy deterioration due to a subject fluid inflow into a gap between a sensor device and an engaging portion is prevented by an underflow inhibitor, the underflow inhibitor overflow to a sensor device surface results in the subject fluid turbulence, causing a flow element output fluctuation risk. One solution is a configuration comprising a sensor device made of a planar semiconductor material with a heating element and an intake air temperature detection element formed thereon, a support member containing an engaging portion the sensor device is engaged to, which is placed at a passage the subject fluid circulates and underflow inhibitor being filled into a void between the sensor device and the support member to prevent the subject fluid from flowing into the void, and a pooling portion being placed to prevent the under flow inhibitor from overflowing out of the void.Type: GrantFiled: December 18, 2009Date of Patent: July 17, 2012Assignee: Mitsubishi Electric CorporationInventors: Shinichiro Hidaka, Masahiro Kawai, Yuji Ariyoshi, Hiroyuki Uramachi
