  • Patent number: 9065098
    Abstract: A safety valve is disposed to cover at least a portion of the center line of the lid plate between the pair of terminals for the positive electrode and the negative electrode. The distance from the center line of the lid plate to end portions of the components to be energized on the safety valve side is equal to or less than the distance from the center line of the lid plate to the outermost circumference of the safety valve. The shadow area obtained by projecting an opening portion of the safety valve in operation onto the plane of the lid plate does not overlap with the respective shadow areas obtained by projecting the electrically connected components, such as the external output terminals for the positive electrode and the negative electrode, onto the plane of the lid plate.

  • Publication number: 20130316201
    Abstract: There is proposed a secondary battery with a large capacity that excels in safety by causing a safety valve to reliably operate to immediately discharge gas produced in the battery in a limited battery space for the purpose of increasing the capacity and the energy density of the battery. The present invention provides a secondary battery with a high battery capacity of 100 Ah or more. A cleavage valve 10 is formed with an opening pressure of 0.2 to 1.5 MPa. In addition, the cleavage valve 10 is configured such that the region provided with the cleavage valve 10 (safety valve region) occupies an area of 0.025 to 0.066 cm2 per 1 Ah of the battery capacity.

  • Patent number: 8311716
    Abstract: A control apparatus for a shift range changeover device determines temporary abnormality, when a detection output of a rotation position of a motor continues to be abnormal for a first abnormality determination period. The control apparatus further determines persistent abnormality and performs predetermined failsafe processing, when the detection output further continues to be abnormal for a second abnormality period following the first abnormality period. If the temporary abnormality is determined within a feedback control permission period, motor feedback control is prohibited to control the shift range to the neutral range. If the temporary abnormality is determined after the feedback control permission period, the same control operation as before the temporary abnormality is performed.

  • Patent number: 8068965
    Abstract: A control apparatus for a shift-position changing mechanism that changes the shift positions of an automatic transmission mounted in a vehicle using a rotational force of an actuator based on a signal corresponding to the state of an operation member, including: a mechanism that generates a rotational force for moving the actuator toward a rotation stop positional-range corresponding to the shift position, based on a rotation stop position of the actuator; a detection unit that detects a rotation amount of the actuator; a control unit that controls the actuator based on the signal and the detected rotation amount; and a learning unit that learns the rotation stop positional-range corresponding to the shift position, based on an amount by which the actuator has been rotated since a control over the actuator executed by the control unit is stopped.

  • Patent number: 7360515
    Abstract: A variable valve mechanism performs a valve lift switching operation for an intake valve. ECU defines valve lift switching characteristics corresponding to the engine operating region and executes the valve lift switching operation based on the switching characteristics. ECU calculates a parameter fluctuation amount of an engine occurring in response to the valve lift switching operation, and corrects the valve lift switching characteristics when the calculated parameter fluctuation amount exceeds a predetermined judgment value.
