Publication number: 20240159591Abstract: An electromagnetic wave sensor includes: a first wire which extends in a first direction; a second wire which extends in a second direction different from the first direction; and an electromagnetic wave detector which is electrically connected to the first wire and is electrically connected to the second wire, wherein the second wire is provided so as to leave an interval with respect to the first wire in a third direction orthogonal to the first direction and the second direction, and the second wire is disposed to three-dimensionally intersect the first wire. At least one wire of the first wire and the second wire includes a wide portion, which is wider than an average value of a width of a portion excluding an overlapping portion of the at least one wire, in the overlapping portion in which the first wire and the second wire overlap each other.Type: ApplicationFiled: October 27, 2023Publication date: May 16, 2024Applicant: TDK CORPORATIONInventors: Maiko KOKUBO, Shinji HARA, Naoki OHTA, Susumu AOKI, Kazuya MAEKAWA, Tadao SENRIUCHI, Yusuke KIMOTO

Patent number: 9425147Abstract: A semiconductor device includes an interlayer insulating film; a wiring formed on the interlayer insulating film so as to protrude there from and made of a material having copper as a main component, the wiring having a thickness direction and having a cross sectional shape of an inverted trapezoid that becomes wider in width with distance away from the interlayer insulating film; and a passivation film formed so as to cover the wiring. The passivation film is made of a laminated film in which a first nitride film, an intermediate film, and a second nitride film are laminated in that order from the wiring side. The intermediate film is made of an insulating material differing from those of the first and second nitride films, and has a tapered portion having a cross sectional shape of a trapezoid that becomes narrower in width with distance away from the interlayer insulating film.Type: GrantFiled: April 1, 2011Date of Patent: August 23, 2016Assignee: ROHM CO., LTD.Inventors: Yuichi Nakao, Tadao Ohta

The passivation film is made of a laminated film in which a first nitride film, an intermediate film, and a second nitride film are laminated in that order from the wiring side. The intermediate film is made of an insulating material (for example, an oxide) differing from those of the first and second nitride films.Type: ApplicationFiled: April 1, 2011Publication date: January 3, 2013Inventors: Yuichi Nakao, Tadao Ohta

Patent number: 5685933Abstract: An FRP drive shaft wherein the shaft body and the flanges are formed in a body and a method of manufacturing the same are disclosed. The shaft body is formed by winding a resin impregnated fiber on a mandrel having pins on its circumferential surface while hooking the fiber on the pins. The fiber is then circumferentially wound to form a hoop-like reinforcing band near each end of the shaft body. After the pins and end parts of the mandrel are removed, each end portion of the shaft body is expanded by a pressing mold to form a flange. After hot setting, the remaining part of the mandrel is removed.Type: GrantFiled: August 23, 1996Date of Patent: November 11, 1997Assignee: Toyota Jidosha Kabushiki KaishaInventors: Tadao Ohta, Shigenori Tamaki, Motohiro Mizuno, Masahiko Morinaga, Yasuyuki Suzuki

Patent number: 5122418Abstract: A composite powder wherein an organic or inorganic core powder is substantially completely covered with one or more types of organic, inorganic, or metallic powders having an average particle size one-fifth or less of the average particle size of the above core powder by means of mixing and compression. The composite powder may be manufactured by mixing and compressing the above core powder and coating powder using a ball mill or other mixer charged with a ball shaped mixing medium of an average diameter of 5 mm or less. This composite powder may be used in, for example, skin treatment agent, makeup type cosmetics, sunburn preventing cosmetics, deodorants.Type: GrantFiled: October 4, 1990Date of Patent: June 16, 1992Assignee: Shiseido Company Ltd.Inventors: Toshihiko Nakane, Masumi Koishi, Hiroshi Fukui, Yutaka Okunuki, Yoshio Yahata, Shigenori Kumagai, Hiroyuki Yokoyama, Eiichiro Yagi, Minoru Fukuda, Tadao Ohta, Fujihiro Kanda, Kazuhisa Ohno, Toshihide Ebisawa, Tomiyuki Nanba, Susumu Takada, Masato Hatao, Masaru Suetsugu
