Abstract: Provided is a hydraulic shovel as an electric work machine, the hydraulic shovel comprising: a charger that supplies electric power from an external power source to a battery to charge the battery; an electric motor that is driven with electric power supplied from the battery; a hydraulic system including a hydraulic pump driven by the electric motor and a hydraulic actuator to which pressure oil is supplied by the hydraulic pump; a control unit that manages a physical quantity indicating the operation status of the electric motor as first operation information, and manages a physical quantity indicating the operation status of the battery including charging and discharging as second operation information; and an output unit that outputs the first operation information and the second operation information.

Abstract: A substrate treatment method includes: performing a first heat treatment on a substrate on which a coating film of a metal-containing resist has been formed and subjected to an exposure treatment, to form the metal-containing resist into a precursor in an exposed region of the coating film; thereafter, performing a second heat treatment on the substrate to condense the metal-containing resist formed into the precursor in the exposed region of the coating film; and thereafter, performing a developing treatment on the substrate.

Abstract: A control device includes a power storage unit, a balance processing unit, and a control unit. The power storage unit includes a plurality of battery cells, and supplies power to a load. In a case where the load stops, the balance processing unit can execute balance processing of reducing variation in the voltage of each of the plurality of battery cells according to the degree of the variation in the voltage. The control unit generates, for display, a state image indicating the state of the variation according to the degree of the variation.

Abstract: This hydraulic shovel used as an electric work machine comprises: an electric motor, an inverter, a hydraulic actuator, a hydraulic pump, a direction switching valve, a pilot pump, a remote control valve, an electromagnetic valve, an accumulator, and a control unit. The accumulator is positioned in an oil path that branches from an oil path for pilot oil extending from the pilot pump to the electromagnetic valve, and accumulates the pilot pressure generated by the pilot pump. The control unit controls the inverter to stop the rotation of the electric motor after an interruption due to a depowered state of the electromagnetic valve.
