Patent number: 12222018Abstract: This shock absorber includes a piston main body and a piston band. The piston main body has, at an outer peripheral portion thereof, a stepped portion including a large-diameter surface portion, a stepped surface portion and a small-diameter surface portion. The piston band has, at an outer peripheral portion thereof, a large diameter portion, a medium diameter portion formed so as to have a smaller diameter than the large diameter portion, and a small diameter portion formed between the large diameter portion and the medium diameter portion so as to have a smaller diameter than the medium diameter portion, in a state before being disposed in a cylinder. At one end on the side close to a tip portion of a piston rod, an inner peripheral surface is inclined toward the piston main body side from the large-diameter surface portion to a small-diameter surface portion of the stepped portion.Type: GrantFiled: September 25, 2020Date of Patent: February 11, 2025Assignee: HITACHI ASTEMO, LTD.Inventors: Kazuya Yamada, Kentaro Yamada, Reiji Nakagawa, Hiroyasu Sato, Sadatomo Matsumura, Wataru Takagi

Publication number: 20230369723Abstract: A busbar includes a first busbar part having a first connection part that is connected to a connection target object, and a first conductive part that is connected continuous to the first connection part. Further, the busbar includes a second busbar part having a second connection part that is connected to a connection target object different from the connection target object that is connected to the first connection part, and a second conductive part that is connected continuous to the second connection part and has a greater resistance value than that of the first conductive part. A current diverting part that diverts a current is formed in the first conductive part such that a shortest path of the current flowing through the first conductive part increases in length.Type: ApplicationFiled: May 3, 2023Publication date: November 16, 2023Applicant: Yazaki CorporationInventor: Hiroyasu TAKAGI

Patent number: 10614698Abstract: A misplacing prevention device capable of preventing leaving items inside and outside a predetermined area is provided. A microprocessor, when a user enters a vehicle interior, determines that the slave device having the ID stored in the memory is not in the vehicle interior based on a communication between a master device and a slave device, detects carrying-in leaving, and notifies the fact. The microprocessor, when the user enters an outside of the vehicle, also notifies a position of the slave device in the vehicle interior.Type: GrantFiled: April 13, 2018Date of Patent: April 7, 2020Assignee: YAZAKI CORPORATIONInventor: Hiroyasu Takagi

Publication number: 20180361992Abstract: The present invention is to provide a vehicle lighting system which can inform a predefined area outside a vehicle to a user. The microcomputer unlocks a door lock when the user approaches a drive area, and opens a sliding door. A lighting section illuminates the drive area of the ground and a movable area of the back door to inform the drive area and the movable area. The microcomputer causes the lighting section to illuminate the drive area and the movable area when detecting that there is a person around the stopped vehicle.Type: ApplicationFiled: April 23, 2018Publication date: December 20, 2018Applicant: Yazaki CorporationInventor: Hiroyasu TAKAGI
