Abstract: A mobile telephone battery cover locking mechanism includes at least one latching member and at least one spring loaded locking member adapted to securely engage the latching member at one end when the latching member is fully inserted in at least one spacing provided at that end. The latching member forces the spring loaded locking member to move against its spring bias when the latching member is being inserted in the spacing with the spring loaded locking member having moved under its spring bias when the latching member is fully inserted in the spacing. The spring loaded locking member may be moved against its spring bias to allow the fully inserted latching member to disengage from the spring loaded locking member.

Abstract: A mobile terminal is provided that includes a terminal body having a battery receiving part, a battery received on the battery receiving part, a battery cover mounted at a rear side of the terminal body, and a battery locking unit for fixing the battery to the terminal body. The battery locking unit may prevent release of the battery due to an external impact.

Abstract: Provided is a complex salt for anti-spotting detergents, the complex salt being formed by the reaction of a photo-bleaching component having a water-soluble anionic substituent and a cationic surfactant. The complex salt is water insoluble in a stationary state, such as hand washing or pre-soaking for machine washing, so it effectively suppress the spotting of the photo-bleaching component into the interwoven webs of fabric. In addition, the complex salt can uniformly and rapidly dissolve in an agitating state, such as when machine washing, to allow the photo-bleaching component to absorb into fabric for effective bleaching and enhanced detergency.
