  • Patent number: 9470602
    Abstract: A soft packaged sealed battery is contained in an airtight container. The airtight container is decompressed and images of the surface shape of the sealed battery in the airtight container before and after decompression are captured by a CCD camera or the like. Whether or not airtightness of the sealed battery is maintained is determined based on a change in the captured images, e.g. a change in the surface shape appearing as luminance differences of pixels. By this determination method, highly accurate airtightness determination is realized by eliminating the influence of invisible fine creases on a sealed battery surface.

  • Patent number: 9140312
    Abstract: A hydraulic control device configured with a source pressure generation section, a hydraulic servo for a clutch provided between an engine and a motor, a control solenoid valve that outputs a regulated source pressure to the hydraulic servo, and a switching section that switches a hydraulic passage, which extends between the source pressure generation section and the hydraulic servo to supply the engagement pressure, between a first and second state in which the hydraulic passage has a high conduit resistance compared to the first state at least until the clutch is engaged. The switching section switches the hydraulic passage into the second state during a failure in which the control solenoid valve is de-energized and the source pressure is directly supplied to the hydraulic servo as the engagement pressure, and switches the hydraulic passage into the first state during normal times when the failure does not occur.
