    摘要: A battery-charging system is provided that does not require removal of batteries from an impact screwdriver (1) for recharging. The battery-charging system includes the impact screwdriver and a charger (20). The impact screwdriver (1) has a nose (3a) to which a tool bit is attached. The impact screwdriver additionally includes a grip handle (4) containing a battery unit (5) whose terminals (10) for recharging are exposed in a surface of a protrusion (7) of the grip handle. The charger (20) includes a charger circuit encased in an enclosure having a base (21) covered with a housing (22). The housing of the charger is provided with a first receiving recess (29) which can receive the nose (3a) of the screwdriver and a second receiving recess (30) which can receive the protrusion (7) of the screwdriver. The system additionally includes a pair of charge terminals of the charger circuit that resiliently projects into the second receiving recess (30). The charger circuit terminals are brought into electrical contact with the corresponding terminals in the protrusion of the impact screwdriver when the screwdriver is set on the charger. While the battery unit is charged, the entire impact screwdriver (1), not the battery unit alone, is set on the charger (20) with the nose placed in the first receiving recess and the protrusion in the second receiving recess.

    摘要: An impact tool includes: a spindle disposed in a housing; an anvil disposed in front of the spindle and rotatably supported by the housing through a metal bearing, a rear surface of the anvil having a bearing hole in which a front end of the spindle is received; an impact mechanism configured to transmit a rotation of the spindle to the anvil; an outer groove formed on an outer periphery of the anvil and opposed to the metal bearing; and a connecting opening radially extending in the anvil and connecting the bearing hole and the outer groove to provide a communication therebetween. The outer groove is formed to have a depth in the range of 3-10% of an outer diameter of the anvil, and the connecting opening opens at a rear end of the outer groove in an axial direction of the anvil.

    摘要: A nucleic acid and a protein increasing expression levels under salt stress provide a nucleic acid with a nucleic acid sequence of SEQ. ID. NO. 1 in Sequence Listing, a variant nucleic acid thereof, a protein with an amino acid sequence of SEQ. ID. NO. 2 in Sequence Listing, and a variant protein thereof. Each of the nucleic acids and the proteins increases an expression level under salt stress. The nucleic acid and the protein are capable of providing a novel protein with a function to impart salt stress tolerance to a plant, and providing a novel gene encoding the novel protein.
