Publication number: 20230160429Abstract: An outer ring case includes an annular guide groove housing an end of each of a plurality of inner rollers. A groove width representing a radial length of the guide groove is greater than a diameter of each inner roller. A radius representing a distance from a bearing axis to an inner wall face of the guide groove that is radially outer is smaller than a distance from the bearing axis to an axial center of each of rollers plus a radius of each inner roller.Type: ApplicationFiled: April 20, 2020Publication date: May 25, 2023Applicant: Mitsubishi Electric CorporationInventors: Naomichi YANAGIDATE, Shinsaku MAEDA

Patent number: 10392310Abstract: The porous plate-shaped filler aggregate includes a plurality of the porous plate-shaped fillers. The porous plate-shaped fillers have a uniform plate shape with an aspect ratio of 3 or more, a minimum length of 0.1 to 50 ?m, a porosity of 20 to 99%, and the deviation of the maximum length among a plurality of the porous plate-shaped fillers, which is obtained by the following formula, is 10% or less. Deviation of the maximum length (%)=standard deviation of the maximum length/average value of the maximum length×100 (Here, ‘maximum length’ is the longest length when the porous plate-shaped fillers are held between a pair of parallel planes.Type: GrantFiled: August 8, 2016Date of Patent: August 27, 2019Assignee: NGK Insulators, Ltd.Inventors: Akinobu Oribe, Hiroharu Kobayashi, Takahiro Tomita, Shinsaku Maeda, Yasutaka Awakura

Publication number: 20180242877Abstract: A magnetic fluid detecting device (1) that detects magnetic fluid that has been injected into a living body has a detector (2) that detects magnetic fluid in the body when it is in contact with or adjacent to the body, an output device (3) that outputs the detection results in a prescribed output form, a controller (4) that controls the output device (3) based on the detected value inputted from the detector (2), and a power supply module (5) that supplies power to the detector (2), output device (3) and controller (4), using a battery B as the power source. The detector (2), output device (3), controller (4) and power supply module (5) are integrated to allow holding with one hand.Type: ApplicationFiled: November 12, 2015Publication date: August 30, 2018Inventors: Moriaki Kusakabe, Masaki Sekino, Tetsu Ookubo, Itsuro Saito, Shinsaku Maeda

Patent number: 9791349Abstract: An end play measurement apparatus is provided that measures end play of a tapered roller bearing of a gear unit. The gear unit supports a large-gear shaft, with which a gear is fitted, via the tapered roller bearing. The end play measurement apparatus includes a power generation unit, which is fixed to the large-gear shaft and generates power to move the gear unit backward and forward in the axial direction, a position change unit, which is interposed between the power generation unit and the gear unit and changes the axial position of the gear unit by using the power of the power generation unit, and a booster mechanism, which has a free end that receives the power of the power generation unit to boost the power.Type: GrantFiled: June 13, 2013Date of Patent: October 17, 2017Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Michinori Hashimoto, Shinsaku Maeda, Hideo Terasawa
