Abstract: An object is to provide a battery module with higher energy density. A battery module includes a plurality of battery cells each including a layered body and an exterior body, in which a first periphery of each of any general battery cells arranged in a layered direction of the layered bodies includes a first bend that is coupled to a first bottom surface formed on a circumference of the exterior body and that bends toward one side in the layered direction, and a first extension extending from the first bend toward the one side in the layered direction, and the first extension includes a first region extending from the first bend to another end in the layered direction of the next battery cell, and a second region extending from the other end in the layered direction of the next battery cell toward the one side in the layered direction.

Abstract: A film forming apparatus (10) includes a mask body (34) configured to expose inner surfaces (14a) of cylinder bores (14), and mask an inner surface (16a) of a crankcase (16). The mask body (34) includes a main body portion (104), a sealing member (106) and a biasing member (108). The main body portion (104) is configured to stretch and contract, and includes a first tubular member (100) and a second tubular member (102) configured to have an insert structure at least part of which is slidable along an axial direction. The main body portion (104) can stretch and contact in a state where at least one end in the axial direction thereof contacts an inner surface of a cylinder block (12). The sealing member (106) is interposed between sliding surfaces of the first tubular member (100) and the second tubular member (102). The biasing member (108) is configured to resiliently bias the first tubular member (100) and the second tubular member (102) in a stretching direction of the main body portion (104).

Abstract: The present invention provides a method for cleaning a carbon coating film, which can clean the carbon coating film that is formed on each portion of a plasma CVD device, and provides the plasma CVD device. The plasma CVD device 1 includes: first and second sealing members 2a and 2b which are formed of insulators and seal both ends of a workpiece W or a dummy workpiece W?, respectively; an anode 3; decompression units 26 which decompress the inside of the workpiece W or the dummy workpiece W?; a source-gas supply unit 6 which supplies a source gas to the inside of the workpiece W; a power source 27; and an oxygen-gas supply unit 8 which supplies oxygen gas to the inside of the dummy workpiece W?.

Abstract: The film forming apparatus includes a mask member and a shield member. The mask member is made of a cylindrical insulation material that can expose inner surfaces of cylinder bores, and mask the inner surface of a crankcase. The shield member is made of a metal material disposed along an inner surface of the mask member.

Abstract: Provided is a preliminary treatment method for a workpiece capable of shortening a cycle time by preventing a nodule from being formed on a carbon film. The preliminary treatment method for the workpiece is performed before a carbon film is formed on a surface of a workpiece W. A bias voltage is applied to the workpiece W disposed in a treatment space S maintained at a predetermined vacuum degree while an oxygen gas is supplied to the treatment space S before a material gas is supplied to the treatment space S, oxygen plasma is generated along the surface of the workpiece W, and oxygen, hydrogen, or water stuck to the surface of the workpiece W is removed.

Abstract: Provided is a carbon-coated member of which the surface can be simply coated with a DLC coating film to achieve sufficient friction reduction. The carbon-coated member is formed by coating a DLC coating film on an internal sliding part of a cylindrical member. The DLC coating film has a hardness of 3.0 to 10.0 GPa, and a kurtosis Rku of 27.0 or less.
