Abstract: A driving tool includes: a body provided with an outlet where a fastener is driven; an urging member attached to the body; and a plunger movable in a projecting direction toward the outlet by extension of the urging member. An urging force in the projecting direction acts on the body from the urging member when the urging member is extended.

Abstract: A sheet (10) for a mask has a first fiber layer (11) and a second fiber layer (12). The second fiber layer (12) has a higher trapping ratio for particles having a particle diameter exceeding 1 ?m and/or a smaller average fiber diameter than the first fiber layer (11). The basis weight of the second fiber layer (12) is from 1 to 20 g/m2. In a natural state, the second fiber layer (12) has a plurality of projections (13) projecting toward a surface of the second fiber layer (12) that is opposite to a surface of the second fiber layer (12) facing the first fiber layer (11) and depressions (14) that are each arranged between corresponding projections (13) of the plurality of projections (13). The depressions (14) have joined portions (15) where the second fiber layer (12) and the first fiber layer (11) are joined to each other.

Abstract: A striking tool includes: a driver which is provided to be slidable toward an ejecting port provided in a tip end of the striking tool so as to strike out a fastener from the ejecting port; a plunger to which the driver is coupled; a plunger urging member which is configured to urge the plunger toward the ejecting port: and a drive mechanism which is configured to move the plunger to accumulate urging force in the plunger urging member. A standby position of the plunger before striking out the fastener can be switched between a usual standby position and a standby position for maintenance closer to the ejecting port than the usual standby position.

Abstract: According to one implementation, a blast treatment device includes at least one nozzle that injects media toward a workpiece, a first tank that supplies the media to the at least one nozzle, a movement structure that moves the at least one nozzle and the first tank, and a second tank that supplies the media to the first tank. The second tank is not moved by the movement structure.

Abstract: According to one implementation, a blast treatment device includes an injection part and a circulating system. The injection part injects media toward a workpiece made with a composite material. The media each has a weight difference from a resinic particle dropping from the composite material. The weight difference is not less than a threshold or more than the threshold. The circulating system recovers the injected media and supplies the recovered media to the injection part. The circulating system has an impurity separation part that removes at least one of impurities and media, of which particle sizes have become small, each included in the recovered media.

Abstract: According to one implementation, a blast treatment method includes: setting a blast treatment condition for a composite material to make a degree of activation on the surface of the composite material within an appropriate range, based on reference information; and manufacturing a blast treated product by the blast treatment of the composite material under the blast treatment condition set to make the degree of the activation within the appropriate range. The reference information shows a relation between a strain amount of a test piece caused by blast treatment under a predetermined blast treatment condition and a degree of activation on a surface of a sample of a composite material by blast treatment, for activating the surface of the sample before painting or bonding, under the predetermined blast treatment condition.

Abstract: A blast processing device includes a first nozzle, a second nozzle, and a moving mechanism. The first nozzle blasts a blasting material toward a workpiece, using first compressed air. The second nozzle blasts second compressed air for adjusting a diffusion range of the blasting material. The moving mechanism moves the first nozzle and the second nozzle over the workpiece.

Abstract: An alkaline battery separator comprises a fused fiber layer, and a fine fiber layer adjacent to the fused fiber layer and comprising fine fibers and second fusible fibers, which are fused in the fine fiber layer, wherein part of the fine fibers are incorporated into the fused fiber layer, so that in determining a delamination strength between the fused fiber layer and the fine fiber layer, delamination occurs in the fine fiber layer and therefore the determination results in failure. A process for manufacturing the separator includes preparing a fused fiber sheet, preparing a slurry containing fine fibers and second fusible fibers, scooping up the slurry with the fused fiber sheet, to thereby incorporate part of the fine fibers into the fused fiber sheet, and fusing the second fusible fibers in the fused fiber sheet.
