Abstract: A manufacturing method for an electrode plate and an electrode plate are provided. The method includes deposition-layer forming to form a deposition layer in which active material particles and binder particles are deposited on a surface of a current collecting foil and heat pressing to form an electrode layer on the surface of the current collecting foil by heating and compressing a deposition-layer-formed current collecting foil having the deposition layer on the surface of the current collecting foil. The deposition layer includes a first deposition layer placed on a side of the current collecting foil and a second deposition layer constituting a surface of the deposition layer. The deposition-layer forming includes forming the deposition layer in which a content rate of the binder particles in the second deposition layer is lower than a content rate of the binder particles in the first deposition layer.

Abstract: When an engine is started in a state where a support member of a multi-coupler is attached to a mating support member, the pressure of hydraulic oil increases in a detection target pipeline part. A pressure detection unit detects the pressure of the hydraulic oil in the detection target pipeline part. A connection state determining unit determines whether a tank-side pipeline part and a motor-side pipeline part are connected to each other, based on the pressure. When the connection state determining unit determines that the tank-side pipeline part and the motor-side pipeline part are not connected to each other in a state where the engine is started, a pressure increase suppression unit carries out an operation for suppressing an increase in the pressure of a hydraulic motor.
