Patent number: 10947064Abstract: An object of the present invention is to provide a technique in which deposition of powder during pneumatic transport can be inhibited by a pipe body having a simple structure. The present invention is a pipe for transporting powder including a transport path which has a portion formed by a curved pipe and through which pneumatically transported powder passes, and a blowing path through which a gas is blown into the transport path from an opening formed on an inner circumferential surface of the curved pipe, in which the blowing path blows the gas in a direction in which the gas blown into the transport path from the opening forms a swirling flow along the inner circumferential surface of the curved pipe.Type: GrantFiled: February 2, 2018Date of Patent: March 16, 2021Assignee: MITSUBISHI CHEMICAL ENGINEERING CORPORATIONInventors: Nobuhiro Tanaka, Katsuhiro Murata, Tetsuji Imamura, Hironobu Takeda, Tomoyuki Osada

Patent number: 10564228Abstract: The magnetoresistive effect element unit includes an anisotropic magnetoresistive effect element and a conductive reset line that, as viewed in a direction orthogonal to both a magnetic sensing direction x? and an easy magnetization direction y? of the anisotropic magnetoresistive effect element, passes through a center of the anisotropic magnetoresistive effect element, extends in a direction inclined from the easy magnetization direction y? so as to form an angle of 45° or less with the easy magnetization direction y?, and is parallel to a plane including the magnetic sensing direction x? and the easy magnetization direction y?. As viewed in the direction orthogonal to both the magnetic sensing direction x? and the easy magnetization direction y?, the reset line has a width that covers an entirety of the anisotropic magnetoresistive effect element.Type: GrantFiled: January 15, 2018Date of Patent: February 18, 2020Assignee: Mitsubishi Electric CorporationInventors: Tomokazu Ogomi, Kenji Shimohata, Jin Inoue, Tetsuji Imamura, Yoshinori Yamaguchi, Takashi Daimon

Patent number: 9726490Abstract: Provided herein is a vibration-type angular velocity sensor capable of improving detection precision of angular velocities around the Z axis and preventing detection precision of angular velocities around the X and Y axes from deteriorating. A weight 3 is columnar or conic. The outline of an outer peripheral portion of a diaphragm 1 has such shape that a straight portion ST is formed at each of four corner portions of a square. Four vibration exciting electrodes 11 are respectively located in four regions partitioned by a first imaginary line L1 and a second imaginary line L2. Four angular velocity sensing electrodes 13 are respectively located in four regions partitioned by a first imaginary diagonal line CL1 and a second imaginary diagonal line Cl2.Type: GrantFiled: September 3, 2012Date of Patent: August 8, 2017Assignee: HOKURIKU ELECTRIC INDUSTRY CO., LTD.Inventors: Masahide Tamura, Osamu Kawasaki, Takayuki Nakano, Shouhei Niikawa, Hidekazu Yano, Tetsuji Imamura

Patent number: 9176084Abstract: Provided herein are a gas sensor element in which deformation of a sensitive portion due to stress may be reduced and a method of manufacturing the gas sensor element. A base insulating layer 9 including a heater wiring pattern 19 is formed on a front surface 3A of a support 3. The base insulating layer 9 includes a fixed portion 15 fixed to the front surface 3A of the support 3, and a nonfixed portion 17 located over an opening portion 5. A cavity portion 7 having the opening portion 5 is formed in the support 3. An electrode wiring pattern 27 and a sensitive film 31 are formed over a central portion 21 of the nonfixed portion 17 of the base insulating layer 9. The nonfixed portion 17 includes the central portion 21 and a plurality of connecting portions 23 connecting the central portion 21 and the fixed portion 15. Four connecting portions 23 each include a base portion 33 and an extended portion 35.Type: GrantFiled: October 1, 2010Date of Patent: November 3, 2015Assignee: HOKURIKU ELECTRIC INDUSTRY CO., LTD.Inventors: Tetsuji Imamura, Daisuke Kuwahara

Patent number: 8529799Abstract: Provided is a manufacturing method of a metal oxide semiconductor material for gas sensors by which an oxide precursor and noble metal colloid particles will not readily cohere in the manufacturing process. The manufacturing process implements a precursor solution synthesis step 1 of synthesizing an oxide precursor solution in which an oxide precursor is dispersed, a pH adjustment step 3 of adjusting the pH of the oxide precursor solution, a precursor-colloid dispersion preparation step 5 of preparing an oxide precursor-noble metal colloid dispersion in which the oxide precursor and the noble metal colloid are dispersed substantially uniformly, a purifying step 7 of purifying the oxide precursor-noble metal colloid dispersion to obtain a purified oxide precursor noble metal colloid dispersion, and a freeze-drying step 11 of freeze-drying an precipitate of the purified oxide precursor-noble metal colloid dispersion.Type: GrantFiled: August 28, 2009Date of Patent: September 10, 2013Assignee: Hokuriku Electric Industry Co., Ltd.Inventors: Tetsuji Imamura, Daisuke Kuwahara, Takayuki Nakano, Takahiro Ishibashi
