  • Patent number: 8504928
    Abstract: A communication terminal displays images on a display device. The communication terminal: receives a material image and corresponding first identification information transmitted from a communication terminal via a network; receives a captured image and corresponding second identification information transmitted from a second communication terminal via the network, the captured image being captured by a camera; compares the first identification information with the second identification information; and displays, when the result of the comparing indicates that the first identification information and the second identification information are the same, the material image and the captured image on a display device in such a manner that at least a part of the captured image overlaps with at least a part of the material image or in such a manner that an outer edge of the part of the captured image abuts an outer edge of the material image.

  • Publication number: 20120042843
    Abstract: OBJECT To provide a hydraulic lash adjuster capable of retaining a large amount of hydraulic oil, in a reservoir communicated with a high-pressure chamber when the engine is stopped. MEANS FOR SOLVING THE PROBLEM A hydraulic lash adjuster including: a cylindrical body (24) having an upper open end, a closed bottom, and a second oil supply hole (27a) formed in the sidewall of the cylindrical body; and a plunger having a top end serving as a plunging end, a sidewall, a bottom end, a high pressure chamber (29) at the lower bottom, and a first oil supply hole (24b) formed in the sidewall, the plunger being slidable on the inner wall of the body. The plunger has a reservoir (28) that communicates with an external oil supply line (32) via the first oil supply hole (24b) and the second oil supply hole (27a). The lash adjuster is provided with a check valve (40a) for opening the oil supply hole (24b) by the oil pressure led from an external oil passage (32) to the oil supply hole (24b).

  • Patent number: 7954468
    Abstract: A mechanical adjuster that automatically increases or decreases or decreases valve clearance is provided that includes: a housing (12) having threaded portions (24, 26); a threaded member (14) thread-coupled with the threaded portion (24); a threaded member (16) connected to the threaded member (14) via mutual rotation prevention-couplings (32, 38) and thread-coupled with the threaded portion (26). When a load acting on the threaded member (14) is equal to or less than a valve closing load, valve clearance is decreased by an integrated rotation of the threaded members (14, 16). with a slip torque of the threaded member (14)>a self-locking torque of the threaded member (16). When a load acting on the threaded member (14) is close to or exceeds a valve opening load, valve clearance is increased by an integral rotation of the threaded members (14, 16) with the absolute value of a slip torque of the threaded member (14)>a self-locking torque of the threaded member (16).
