Publication number: 20220339910Abstract: Provided is an interlayer film for laminated glass capable of suppressing the change in sound insulating property of laminated glass in a relatively high temperature region. An interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass having a one-layer structure or a two or more-layer structure, and when the interlayer film is sandwiched between two sheets of green glass having a thickness of 2 mm to obtain a laminated glass X with a size of 25 mm long x 300 mm wide, an absolute value of difference between a secondary resonance frequency of the laminated glass X before irradiation with xenon light and a secondary resonance frequency of the laminated glass X after irradiation with xenon light determined by a specific xenon light irradiation test is 70 Hz or less, a loss factor at 20° C. of the laminated glass X is 0.24 or more, and a solar transmittance of the laminated glass X is 50 or less.Type: ApplicationFiled: July 14, 2020Publication date: October 27, 2022Applicant: SEKISUI CHEMICAL CO., LTD.Inventors: Kinryou CHOU, Yuuma TAKEDA, Tatsuya IWAMOTO, Shougo YOSHIDA, Shingo OKAZAWA

Publication number: 20220250357Abstract: Provided is an interlayer film for laminated glass capable of enhancing the sound insulating property of laminated glass in a relatively low temperature region. An interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass having a one-layer structure or a two or more-layer structure, and when the interlayer film is sandwiched between two sheets of green glass having a thickness of 2 mm to obtain a laminated glass X with a size of 25 mm long×300 mm wide, an absolute value of difference between a secondary resonance frequency of the laminated glass X before irradiation with xenon light and a secondary resonance frequency of the laminated glass X after irradiation with xenon light determined by a specific xenon light irradiation test is 60 Hz or more, a loss factor at 20° C. of the laminated glass X is 0.25 or more, and a solar transmittance of the laminated glass X is 50% or less.Type: ApplicationFiled: July 14, 2020Publication date: August 11, 2022Applicant: SEKISUI CHEMICAL CO., LTD.Inventors: Shougo YOSHIDA, Tatsuya IWAMOTO, Yuuma TAKEDA, Shingo OKAZAWA, Kinryou CHOU

Patent number: 11008906Abstract: An oil supply device includes an oil pump and an oil control valve. The oil control valve is connected to a control oil chamber of the oil pump via a control oil passage that includes an oil descent passage and an oil rise passage. One end of the oil descent passage on the control oil chamber side is disposed at a position closer to a bottom of the vehicle than the other end on the oil control valve side. The oil rise passage is disposed at a position closer to the control oil chamber side than the oil descent passage. One end of the oil rise passage on the control oil chamber side is disposed at a position closer to a top of the vehicle than the other end on the oil control valve side.Type: GrantFiled: March 7, 2018Date of Patent: May 18, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shingo Okazawa, Michitaka Yamamoto

Patent number: 10738666Abstract: A control system for an oil supply mechanism includes an oil pump, a hydraulic pressure sensor, a drive shaft, a pump pulley, a toothed belt, and an output shaft. An electronic control unit included by the control system detects an abnormality of the toothed belt based on a comparison result between an actual value and a theoretical value that are frequencies of pressure pulsations of oil. The actual value is a value calculated based on time fluctuations of a hydraulic pressure detected by the hydraulic pressure sensor. The theoretical value is a value calculated based on a rotational speed of the output shaft and the number of teeth of an inner rotor.Type: GrantFiled: September 13, 2019Date of Patent: August 11, 2020Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Shingo Okazawa

Patent number: 10584803Abstract: A solenoid valve includes: a cylindrical spool that has an annular groove in an outer surface and moves along an axial direction under a driving force generated by a current being applied to a solenoid part; a cylindrical sleeve that has a through-hole capable of communicating with the annular groove and houses the spool; and an urging member that urges the spool by an urging force acting in a direction opposite from a direction in which the driving force is generated. When no current is applied to the solenoid part, a part of the through-hole communicates with the annular groove. When a current is applied to the solenoid part, an area of communication between the through-hole and the annular groove increases as the spool moves under the driving force acting against the urging force.Type: GrantFiled: June 1, 2017Date of Patent: March 10, 2020Assignees: AISIN SEIKI KABUSHIKI KAISHA, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Daisuke Toyama, Shinya Amano, Yoshikuni Sue, Hisashi Ono, Shingo Okazawa, Michitaka Yamamoto, Daisuke Okanishi, Noboru Takagi, Takayuki Hosogi
