  • Patent number: 7961596
    Abstract: In a ring redundant communication path control method, each of transfer apparatuses periodically transmits an inspection frame for inspecting a communication path, detects a failure of the communication path when the inspection frame is not received for a fixed time, transmits a non-arrival notification frame for notifying that the inspection frame has not arrived yet, and detects a failure of the communication path when the non-arrival notification frame is received.

  • Publication number: 20100050992
    Abstract: In a variable stroke internal combustion engine, by determining the relationships of a connecting point (D) between a first link (4) and second link (5) and a connecting point (B) between the second link (5) and a control link (12) with respect to a center (A) of a crankpin (9) to be such that ?D<?B holds over an entire rotational angle of the crankshaft, where ?D is the distance between D and A and ?B is the distance between B and A, an adequate durability of the engine can be ensured without increasing the weight thereof.

  • Patent number: 7321594
    Abstract: An output port circuit is provided for a router apparatus which routes and transmits a received packet. Each flow is constituted by continuous packets and belongs to a bandwidth-guaranteed class or a best-effort class. A controller controls storage and reading of a packet into and from a storage unit. Upon allocating a basic volume that is a criterion of a memory size stored in the storage unit to each flow to which the packet to be transmitted belongs, the controller manages the basic volume of each flow of the packet belonging to the bandwidth-guaranteed class by individually allocating the basic volume by the memory size required by each flow, and manages the basic volume of each flow of the packets belonging to the best-effort class by collectively allocating the memory size obtained by subtracting a sum of respective basic volumes allocated to the bandwidth-guaranteed class from an entire memory size.

  • Patent number: 6899650
    Abstract: A hydraulic automatic tensioner for adjusting the tension of a bell includes a first member with a piston formed integrally, a second member combined with the first member and axially movable relative to the first member, a cylinder formed integrally with the second member, together defining a fluid-reservoir chamber for hydraulic fluid, axially slidably receiving the piston, and a spring pushing the members apart. The piston and cylinder form a pressure chamber filled with hydraulic fluid. The second member has a leak passage through which fluid flows from the pressure chamber into the fluid-reservoir chamber. A control valve is placed in the leak passage, inhibiting flow of fluid from the pressure chamber into the fluid-reservoir chamber. A control device moves the control valve to close the leak passage when activated and makes it ineffective when deactivated so that the pressure chamber communicates with the fluid-reservoir chamber via the leak passage.

  • Patent number: 6845832
    Abstract: The present invention is made to operate auxiliary machine while an engine is stopped, to start an engine and to charge a battery by providing a single motor and a simple construction and by providing a simple control operation. An engine system comprises an engine, a motor, and auxiliary machine, and further comprises a planetary mechanism having three elements comprising a sun gear, a carrier and a ring gear, to which any one of an output shaft of the engine, an output shaft of the motor and a drive shaft of the auxiliary machine are respectively connected, a uniting connection device capable of uniting two or more elements of the planetary mechanism, and a rotation direction restriction device which restricts a rotation direction of the drive shaft of the auxiliary machine to one direction.

  • Publication number: 20030171179
    Abstract: A hydraulic automatic tensioner for adjusting the tension of an endless belt in a power transmitting mechanism for transmitting power to engine accessories of an internal combustion engine through the belt comprises: a fixed first member (11), a piston (PS) formed integrally with the first member (11), a movable second member (12) coaxially combined with the first member (11) so as to be axially movable relative to the first member (11), a cylinder (CY) formed integrally with the second member (12), defining a fluid-reservoir chamber (R) for storing a hydraulic fluid together with the first member (11), and provided with a leak passage (20), axially slidably receiving the piston (PS), a spring (S) pushing the first and the second member (11, 12) away from each other. The piston (PS) and the cylinder (CY) form a pressure chamber (P) filled with the hydraulic fluid.
