  • Patent number: 10316808
    Abstract: To reduce collision noise created by the operation of an electromagnetic suction valve provided on a high pressure fuel supply pump, the mass of a member which collides by magnetic attractive force is reduced. The noise generated when a core and an anchor collide with each other by magnetic attractive force depends on the magnitude of the kinetic energy of a moving element. The kinetic energy to be consumed in the collision is only the kinetic energy of the anchor. The kinetic energy of a rod, being absorbed by a spring, does not contribute to the noise; thus, the energy when the anchor and the core collide with each other can be reduced, whereby the noise to be created can be reduced.

  • Patent number: 7310812
    Abstract: A system allows a user to select a service on a device and request a service executing function of a server to carry out the service. An authentication function authenticates the user and searches the functions of devices required in the requested service within the authority given to the user. The function acquires and registers the right to use in a device-configuration managing function through a right-to-use managing function. An adaptor delivering function delivers specifications for setting connections between functions required for execution of the service and a group encryption key generated by a key-generating function to devices. Device coordinating functions set device-embedded functions based on the received specifications. The functions conduct cipher communication with other devices using the key and carry out the service.

  • Patent number: 7228561
    Abstract: In distributed system for operating devices in association with one another, a device responsible for determining whether or not an access is permitted, and criteria for determination are hidden from accessing device or user, and flexible access control is provided among devices without need for previously defining accessible devices or user's identifiers. Communication process opens data communications which are interactions between devices to permit indefinite number of other devices to monitor data. A behavior monitoring process acquires interaction within particular device or between other devices in system for storage in behavior log table. Access control process matches the behavior log table with access control policy to determine whether or not device should be associated with target device from which process request is received, or with a target device to which a process program of the particular device attempts to access.
