Abstract: The induction of thermal runaway is prevented with lower manufacturing costs. In a battery pack, a heat resistant wall is disposed between cylindrical rechargeable battery cells and arranged in parallel to one another, and the heat resistant wall and the battery cells are housed in an exterior case. The heat resistant wall has heat insulating recesses in surfaces each facing the surface of a corresponding one of the battery cells, the heat insulating recesses each forming an air layer having a length extending in the longitudinal direction of the battery cells and a width extending in the circumferential direction of the battery cells.

Abstract: According to one embodiment, a fan scrubber includes an inlet pipe to be connected to a post-stage side of a vacuum pump, in a state where a film preparation apparatus is arranged at a pre-stage before the vacuum pump, a process chamber connected to the inlet pipe, and containing a fan connected to a main shaft of a motor, a heater configured to heat the inlet pipe, and a controller configured to control turning on/off of the heater. The controller turns off the heater, when a signal received from the film preparation apparatus has been switched from a film preparation signal to a cleaning signal.
