Patent number: 10931160Abstract: An actuator is provided that is smaller in size and has a simpler structure, as compared with a conventional one. The actuator is composed of a driving mechanism that includes an electric motor, and a housing that houses the driving mechanism. The housing includes an air hole that communicates the inside of the housing with the outside thereof, a filter that covers the air hole, and a motor box that surrounds the electric motor. At least one of members of the motor box acts as a scattering prevention wall that prevents lubricant from scattering to the electric motor. The air hole is formed in a member of the motor box other than said at least one of members of the motor box.Type: GrantFiled: March 16, 2018Date of Patent: February 23, 2021Assignee: MURAKAMI CORPORATIONInventors: Hiroya Miwa, Akira Fukai, Fumitaka Kitagawa

Patent number: 10665992Abstract: An actuator capable of enhancing versatility is provided. The actuator prevents a charging connector from coming off a power receiving connector, and includes: a hollow housing; and a driving mechanism that is housed in the housing. The driving mechanism includes: an electric motor; a cam member that is driven by the electric motor; and a lock pin that interlocks with the cam member and moves from an initial position to a restricting position where the charging connector is prevented from coming off. A rotation axis of the cam member is arranged substantially perpendicular to a reference plane defined by a line segment running in the direction of plugging the charging connector and a line segment extending from the housing toward the power receiving connector.Type: GrantFiled: March 15, 2018Date of Patent: May 26, 2020Assignee: MURAKAMI CORPORATIONInventors: Hiroya Miwa, Akira Fukai, Fumitaka Kitagawa

Patent number: 10461471Abstract: Provided is a structure for installing an actuator capable of preventing mischief to a connector. The structure for installing the actuator has an installing surface provided on a power receiving connector, and the actuator. The actuator includes a lower housing to be installed over the installing surface, and an upper housing to be attached to the first housing, and the connector for connecting the lower housing and the upper housing. The installing surface has a step surface for hiding a tip of the connector.Type: GrantFiled: March 16, 2018Date of Patent: October 29, 2019Assignee: MURAKAMI CORPORATIONInventors: Hiroya Miwa, Akira Fukai, Fumitaka Kitagawa

Publication number: 20190263322Abstract: A monitor inner minor for a vehicle includes a liquid-crystal shutter and a display device disposed behind the liquid-crystal shutter. The liquid-crystal shutter is switched between a mirror state and a transmissive state by electrical driving. An entire front shape of the monitor inner mirror for a vehicle is a horizontally-long shape. A power supply section that supplies a drive voltage to the liquid-crystal shutter is disposed at one short side of left and right short sides of the liquid-crystal shutter. Liquid-crystal encapsulation section is disposed on the other short side of the left and right short sides of the liquid-crystal shutter. The liquid-crystal encapsulation section is formed by sealing an injection port used for injecting liquid crystal to the liquid-crystal shutter with a seal material.Type: ApplicationFiled: September 6, 2017Publication date: August 29, 2019Applicant: MURAKAMI CORPORATIONInventors: Daiki HAYASHI, Akira FUKAI, Fumitaka KITAGAWA

Patent number: 8215781Abstract: In a mirror for an automobile, the adoption of resin mirror body to a mirror plate can decrease the weight of the mirror body, and the mirror plate is fixed onto a mirror holder through the welding. Therefore, this eliminates the usage of both-sided adhesive tape or adhesive agent, makes assembly processes less complicated, and thus the reduction in production cost is achieved. Furthermore, since the mirror plate can be fixed onto the mirror holder firmly and strongly even when the mirror plate is not pressed strongly to the mirror holder, excessive load on the mirror holder or the mirror plate becomes avoided. In addition, at the time of the production stage, some dimensional variation in the edge part of the mirror holder or the peripheral edge of the mirror plate becomes easily acceptable.Type: GrantFiled: November 17, 2009Date of Patent: July 10, 2012Assignee: Murakami CorporationInventors: Fumitaka Kitagawa, Akira Fukai
