Abstract: In a manufacturing process of a battery or a circuit board, or a printing process, there is a case where a long sheet material is conveyed from an unwinding unit to a winding unit. One object of the present disclosure is to provide a technique capable of preventing the long sheet material from being rubbed by a roller when the material is conveyed. The present disclosure relates to a conveyor adapted for a battery manufacturing process. The conveyor comprises a roller configured to convey a long sheet material, a shaft through the roller; a bearing installed between the roller and the shaft, and a driver configured to rotate the shaft in the same direction as a rotating direction of the roller conveying the long sheet material.

Abstract: A coating device includes a backup roll configured to transport a workpiece; a coating die configured to discharge a coating liquid onto the workpiece; a drive section capable configured to drive the backup roll; and a heat dissipation section configured to dissipate heat generated in the drive section.

Abstract: A display device comprises a display panel, a protective glass sheet disposed on the front face side of the display panel, a housing that holds the display panel, an exhaust fan that generates an air flow in the space between the display panel and the protective glass, an intake opening that draws air to be sent into the space in from the outside of the housing, an exhaust opening that exhausts air that has passed through the space to the outside of the housing, an ambient temperature sensor that senses the ambient temperature and the temperature of the intake opening, an exhaust-side temperature sensor that senses the temperature of the exhaust opening, and a controller that calculates the difference between the temperature sensed by the intake-side temperature sensor and the temperature sensed by the exhaust-side temperature sensor as a difference value, and determines the rotational speed of the exhaust fan on the basis of the ambient temperature and the difference value.
