  • Patent number: 11885277
    Abstract: A method for controlling fuel injection to an engine may include calculating an amount of air passing through a throttle, which is actually controlled, from a calculated amount of air in an intake manifold, which is calculated from a pressure value detected by a pressure sensor installed in the intake manifold connecting the throttle and a cylinder to each other, and a calculated pressure change in the intake manifold. The method may further include predicting an actual amount of air to be sucked into the cylinder when mixed with fuel from the calculated amount of air in the intake manifold and the calculated amount of air passing through the throttle. The method may also include injecting an amount of fuel according to the predicted actual amount of air to be sucked into the cylinder.

  • Patent number: 10715666
    Abstract: While using a communication system in which groups of destinations on a network are managed, and any one of the groups can be specified as a destination, if a group needs to be changed, added, or deleted, updating the system on the network is required, which increases load of maintenance. To address such a problem, an operation input receiving unit of a terminal receives selection of a group including destination information that represents destination candidates of communication. A destination management unit of the terminal determines a destination among the destination candidates represented by the destination information included in the selected group. A sending and receiving unit of the terminal makes a request for starting communication with the determined destination, to a management system.

  • Patent number: 10581936
    Abstract: An information processing terminal includes: circuitry to receive from a management system via a network, a candidate identifier of each one of one or more candidate counterpart information processing terminals that are previously registered for the information processing terminal; and to determine, in response to acceptance of an identifier that has been input, whether the accepted identifier matches any one of the candidate identifiers being received. Based on a determination indicating that the accepted identifier matches any one of the candidate identifiers, the circuitry transmits to the management system first request information requesting to start communication with the candidate counterpart information processing terminal identified with the accepted identifier.

  • Patent number: 7377736
    Abstract: A cylinder which can precisely feed a piston rod 3 into three different positions. The cylinder includes a spring receiving member 14 which is placed coaxially with the piston rod in a piston room. Movement of the piston 4 is limited by one end of the piston room and a stopper 8 formed on the piston rod which prevents the piston from moving in the opposite direction. A first spring member 15 is disposed in the cylinder tube 2 to separate the spring receiving member from the piston. A hollow 9 is formed on the periphery of the piston rod at a further position from the piston than the stopper and a stop pin 11 in the cylinder tube 2 which is biased in the direction of the hollow by a second spring member 12 engages with the hollow. A load port utilizes the cylinder for a production system.
