Abstract: The invention relates to a spud system for a dredging vessel with a longitudinal direction, which spud system comprises; a spud carrier for mounting a spud therein in a vertical stance and which spud carrier is mounted for limited rotation around a horizontal transverse axis and is moveable with respect to the dredging vessel in a longitudinal direction for advancing the dredging vessel, and a spud carrier drive system coupled with the dredging vessel and the spud carrier for driving the spud carrier with respect to the dredging vessel.

Abstract: A spud system for a dredging vessel with a longitudinal direction includes a spud carrier for mounting a spud therein in a vertical stance and which spud carrier is moveable with respect to the dredging vessel in a longitudinal direction for advancing the dredging vessel, a spud carrier drive system coupled with the dredging vessel and the spud carrier for driving the spud carrier with respect to the dredging vessel. The spud carrier drive system includes a hydraulic drive cylinder for controlling the position of the spud carrier. The spud system further comprises a hydraulic system comprising a parallel hydraulic cylinder in fluid parallel connection with the hydraulic drive cylinder and presstressing means coupled with a rod of the parallel hydraulic cylinder such that said rod is forced towards a central position.

Abstract: There is disclosed a device for flexibly adjusting the strobe pulse width corresponding to the heat-generating resistance grade of a thermal printer head through a DIP switch. The DIP switch generates a number of states of voltages corresponding to the grade number of the heat-generating resistance of the thermal printer head. The DIP switch keeps voltage suited for the heat-generating resistance grade of the thermal printer head to supply it to a CPU.

Abstract: Image recording is indirectly achieved on a recording sheet via an intermediate transferring medium. First, the circumferential surface of a rotatable transferring medium having heat-transferable ink contained therein is fused or softened in response to image information by means of a recording electrode which is disposed at the position opposite to the transferring medium while the intermediate transferring medium is interposed therebetween. After completion of the first transferring step the ink image which has been transferred onto the intermediate transferring medium is transported to the position where a second transferring step is achieved while the ink image is kept in the fused or softened state. The second transferring step is achieved in such a manner that the ink image is transferred onto the recording sheet under the effect of pressure which is imparted by a pressure roller. The intermediate transferring medium may be made of electric conductive material.
