New design for semi-automatic weapon for several tubes cartridges loading system for long guns, wherein an in-between connection steel part fixes the barrel to the receiver. Tampons, having a primary absorbent member which is constructed from an absorbent material compressed to a self-sustaining form and a mass of secondary absorbent material are disclosed. The method for reconstruction according to the invention comprises the following steps for each coding entity coded in INTER mode:determining for the coding entity at least one reference picture, andreconstructing the coding entity from the at least one reference picture with coding tools configured by coding parameters associated with the coding tools. The microwave generating element applies the microwave magnetic field having a width broader than the width of the recording magnetic field generated by the main magnetic pole of the magnetic head to the magnetic recording medium. The function may cause relatively higher percentages of the current progressive pool size to be payable to players when the current progressive pool amount is greater than a target progressive pool size and relatively lower percentages of the current progressive pool size to be payable to players when the current progressive pool size is less than or equal to a target progressive pool size.
