Abstract: A system for detecting leakage of email addresses generates an alias email address that will be used by a user to register with a web service. The alias email address is an alias for a primary email address of the user, and is paired with the web service. The web service is included in a whitelist upon confirmation from the web service that the alias email address has been registered with the web service. Emails that are addressed to the alias email address and from the web service are forwarded to the primary email address. Emails that are addressed to the alias email address but is not from the web service are detected to be suspicious.

Abstract: A circular saw machine capable of suppressing a cutting-bending of a circular saw blade during cutting, and improving processing accuracy for a cutting surface of a workpiece, regardless of a size of a width of the workpiece. A circular saw machine has: a processing head capable of moving in a cutting direction and its opposite direction and having a circular saw blade capable of rotating; and a movable saw blade guide set provided to be movable in the cutting direction and the opposite direction on the processing head, for guiding to pinch a body part of the circular saw blade on a diameter direction inner side of a cutting region in the circular saw blade. The movable saw blade guide set is configured to move relatively with respect to the processing head in the opposite direction, in coordination with a movement in the cutting direction of said processing head.

Abstract: A removable mass storage device includes a controller and a memory storage area. A secured portion of the memory storage area may be a permanently write-protected portion. Programs provided by the operating system, e.g., application programming interface (API), for accessing the memory storage area cannot disable the write-protection of the permanently write-protected portion, preventing them from writing to the permanently write-protected portion. The controller does not enforce the write-protection against a security command of a secure library, allowing writing to the permanently write-protected portion using the security command. The security command may be issued by an API of the secure library. The secured portion of the memory storage area may also be a hidden portion that is not visible to the operating system, but is accessible by way of the secure library.

Abstract: A device for manufacturing a connecting rod comprises a fixed stage secured onto a base, a movable stage so installed as to be move close to and apart from the fixed stage, and a set of backup cylinders displacing the overall movable stage along the axial direction of the connecting rod. The set of backup cylinders are substantially simultaneously biased to displace a cap part together with the movable stage until the fractured surface of the cap part of the connecting rod abuts on the fractured surface of the rod part of the connecting rod held on the fixed stage. Consequently, the removal and release of chips produced on the mating fractured surfaces can be promoted.
