Abstract: -- A first backup of source data is performed. A second backup of the source data is determined to be performed at least in part by determining a plurality of objects that have changed since the first backup and determining a corresponding backup type for each of the plurality of objects that have changed since the first backup. Based on the determined corresponding backup types, a second backup of the source data is performed including by performing an incremental backup of a first portion of the plurality of objects that have changed since the first backup and a full backup of a second portion of the plurality of objects that have changed since the first backup.

Abstract: The present invention includes a mold set, a deformation generating element, and an engaging element. The mold set has a pipe storing channel, a deformation portion, and a positioning recess. The deformation generating element has a deformation generating portion and a pushing portion with an outer working thread. The engaging element has an axial positioning portion and a working channel with an inner working thread. Therefore, the deformation generating portion can move toward the deformation portion for pipe flare processing work and a view hole is provided for viewing. So, no threaded hole is required for the mold set. The view hole allows the user to inspect the pipe end's position being correct or not. The manufacturing for the engaging element is easy. The engaging element has a guiding function.

Abstract: A tube cutting device with a rapid separable handle comprises a tube cutter and a handle. The tube cutter comprises a C-shaped housing, a one-way rotation part, and a limit part. The handle comprises a grip part, a C-shaped guiding seat, a separation control part, and a control button. The C-shaped guiding seat is for unidirectional rotation of the C-shaped housing via the one-way rotation part. In a combination position, it engages with the limit part so that the tube cutter and the handle are mutually fixed. In a separation position, it is separated from the limit part so that the tube cutter and the handle are separable from each other for independently perform tube cutting.

In a separation position, it is separated from the limit part so that the tube cutter and the handle are separable from each other for independently perform tube cutting. Therefore, this invention has advantages of the handle being separable from or combinable with the tube cutter as needed, and quick, easy and convenient switch between different usage modes of the tube cutting device.

Abstract: A tube cutter having a relative movement generating portion including a relative movement generating portion, a tube cutting base and a tube cutting slider. A manual input portion of the relative movement generating portion is to be held by a user's hand. A cutting blade, two auxiliary rollers and a feeding spring are disposed between the tube cutting base and the tube cutting slider. After the user applying a holding force, the pushing plate will compress the spring in the tube cutting slider so that the cutting blade feeds in. In case the applying force is too large, the entire tube cutting base and the cutting slider will be locked via the stopping plate. Thereby avoiding an over-applying force destroying the pipe to be cut. The tube can be automatically feed in or feed in by a holding force of a hand.

And, it can feed in by holding force of hand.

Abstract: The inventions of the application relates to a method and device for detecting the oviposition of crustaceans, which comprises sealing off one of the two gonopores of a female crustacean, covering the other gonopore with a bag, and detecting eggs laid into the bag with a actor. By using this method and device, unfertilized eggs of crustaceans can be easily obtained, thus facilitating the culture and strain improvement of crustaceans.

Abstract: A rotatable tube cutter for cutting a tube-like work piece is disclosed. This rotatable tube cutter mainly comprises a fixing portion, a rotatable portion, a cutting blade assembly, and a feeding assembly. By rotating a feeding knob, the feeding amount can be easily controlled. So, this invention is easy to operate by one hand. It is able to work in a limited available space via repeating lift and press movements. It is possible to work in the traditional full circle rotation method. And, it has manual and automatic dual feeding modes.
