  • Patent number: 8999572
    Abstract: Provided herein is a lead-acid battery for which the risk of breakage of a current collecting lug part of a plate while in use is eliminated by simple means. At least a positive plate group of the lead-acid battery includes: one or more plates each including a current collector having a current collecting portion formed by expanding or punching a lead alloy sheet manufactured by cold rolling, and one or more current collecting lug parts unitarily formed with the current collecting portion; and a strap formed by a cast-on strap casting method and coupled to the one or more current collecting lug parts. The current collecting lug part is formed with an elongated protrusion extending in a direction away from the current collecting portion. The elongated protrusion continuously extends in a direction toward the current collecting portion of the plate from inside the strap.

  • Publication number: 20150071155
    Abstract: According to the embodiments, a communication apparatus stores therein an operation mode indicating whether the communication apparatus is a publisher or a subscriber, and includes a message processing unit that generates a transmission message and analyzes a reception message and a nonvolatile memory. When the communication apparatus is subscriber, the communication apparatus sends a repair message to request a retransmission of a data chunk not successively received. When the communication apparatus is publisher, the communication apparatus selectively retransmits the data chunk based on the repair message.

  • Publication number: 20150046634
    Abstract: According to embodiments a memory system is connectable to a host which includes a host controller and a host memory including a first memory area and a second memory area. The memory system includes an interface unit, a non-volatile memory, and a controller unit. The interface unit receives a read command and a write command. The controller unit writes write-data to the non-volatile memory according to the write command. The controller unit determines whether read-data requested by the read command is in the first memory area. If the read-data is in the first memory area, the controller unit causes the host controller to copy the read-data from the first memory area to the second memory area. If the read-data is not in the first memory area, the controller unit reads the read-data from the non-volatile memory and causes the host controller to store the read-data in the second memory area.

  • Patent number: 8818690
    Abstract: An air-fuel ratio control apparatus for an internal combustion engine includes an air-fuel ratio sensor having an output characteristic which is nonlinear with respect to the air-fuel ratio of exhaust gas. An output deviation converter is configured to convert an output deviation to a first predetermined value if an output value of the air-fuel ratio sensor is on a richer side of a predetermined target value and to a second predetermined value if the output value is on a leaner side of the target value. A control input calculator is configured to calculate a control input to feedback-control the output value of the air-fuel ratio sensor such that the output deviation converted by the output deviation converter is to be zero. An air-fuel ratio controller is configured to control the air-fuel ratio of exhaust gas using the control input calculated by the control input calculator.

  • Patent number: 8725304
    Abstract: A plant controller includes a feedback controller configured to calculate a control input provided to a plant so that a control output of the plant matches a target value. The feedback controller includes a controller transfer function that is a transfer function of the feedback controller. The controller transfer function is expressed by a product of an inverse transfer function of a transfer function of a control target model obtained by modeling the plant and a disturbance sensitivity correlation function defined using a sensitivity function. The sensitivity function indicates sensitivity of a disturbance to be applied to the plant with respect to the control output. The sensitivity function is defined by using a response characteristic parameter that indicates a response characteristic of the plant.
