  • Patent number: 11411224
    Abstract: A highly reliable secondary battery is provided, in which a short circuit between a positive electrode plate and a negative electrode plate is prevented. The negative electrode plate includes a negative electrode core and a negative electrode active material layer formed on the negative electrode core. An electrode assembly includes a negative electrode core-stacked portion including stacked layers of the negative electrode core, and the negative electrode core-stacked portion is joined to a first surface of the negative electrode current collector to form a joined portion. The irregularity-formed portion is formed on a second surface of the negative electrode current collector that is opposite to the first surface and is located in a portion of the negative electrode current collector in which the joined portion is formed. A sheet member used as a cover member is disposed on the second surface so as to cover the irregularity-formed portion.

  • Publication number: 20200002914
    Abstract: A hydraulic excavator 1 includes a computer-aided construction controller 60 for performing machine control to operate a front work implement based on detected results from posture sensors 63, 65 and 67 and predetermined conditions. The computer-aided construction controller 60 has a calibration posture storing section 60a that stores at least one predetermined calibration posture of the front work implement for calibrating the posture sensors, and a calibration posture controlling section 60b that carries out the machine control to inactivate the hydraulic actuators if detection target values of the posture sensors in the calibration posture and the detected results from the posture sensors are equal to each other. The time required for calibration can thus be shortened by increasing the operability for adjusting a calibration posture.
