  • Patent number: 11448292
    Abstract: To provide a tensioner that can keep the oil pressure in an oil pressure chamber stable and consistently generate suitable reaction force and damping force to impact loads to reduce looseness in the chain and noise. A piston is set such as to partition an inner space of a plunger into an adjustment space on the front side and the oil pressure chamber on the rear side, a piston restricting member restricting the movement of the piston toward the adjustment space. An oil relief mechanism is configured to cause the piston to move forward when oil pressure in the oil pressure chamber rises so as to discharge oil inside the oil pressure chamber to the outside. The piston restricting member has an orifice function that can control the amount of discharged oil.

  • Patent number: 11403401
    Abstract: A method for checking an integrity of an object to be deployed to a cluster is provided. The method detects a resource creation request. The method, responsive to the request being an initial resource creation request for the object, verifies the integrity of the object based on properties in the request to create a release secret in the cluster for a positive integrity verification result for the object. The release secret represents a specific deployment configuration of the object on the cluster. The method, responsive to the request being other than the initial resource request, checks if the request corresponds to the specific deployment configuration of the object by checking against the release secret in the cluster. The method, responsive to the request corresponding to a deployment of the object and the release secret being present in the cluster, creates a resource requested by the request in the cluster.
