Abstract:
A rudder assembly, including a steering engine; an axial hollow rudder stock; a rudder blade; a gas release unit; and a tiller. The steering engine is disposed in a vessel stern. The tiller is connected to the steering engine. The axial hollow rudder stock includes a through hole. The through hole is small and disposed along the axis of the axial hollow rudder stock. The gas release unit is disposed in the vessel stern, and includes a control cabinet. The control cabinet includes a reagent storage tank, a reagent conveying hose connected to the reagent storage tank, a compressed air bottle, a pressure hose connected to the compressed air bottle, and a console. The pressure hose and the reagent conveying hose pass through the through hole of the axial hollow rudder stock, and then communicate with the cavity of the rudder blade.
Abstract:
An unmanned surface vehicle (USV) including a main body; a slideway; and an automatic recovery unit. The slideway includes pulleys, slide rails, sleepers, end plates disposed at two sides of the sleepers, and baffle plates. The automatic recovery unit includes a buoy, a connection rod, a downhaul, an electromagnetic fixer, a winch, an upper cable, a storage box, and a recovery net. The slideway is fixed on the afterdeck of the main body and the tail end of the slideway sticks out the side boundary of the afterdeck. The baffle plates are disposed on the upper end of the end plates. The vertical height of the end plates is larger than the maximum vertical height of the pulleys and the slide rails. The baffle plates on the upper end of the end plates limit the displacement of the buoy in the vertical direction.
Abstract:
An underwater operation platform, including: a main body; two ducted propellers disposed at the tail end of the main body; a living building; pile legs; a tower crane; a submergence module; lifting devices; and a gantry crane. The main body includes a deck and a moonpool. The submergence module includes a support plate, a plurality of truss members, and a base plate. The living building disposed on the front end of the deck. The pile legs are disposed at the four corners of the main body, respectively. The deck includes two parallel pathways which are located at two sides of the moonpool, respectively, for supporting the gantry crane. The lifting devices are disposed on the deck and are close to four corners of the moonpool. The support plate and the base plate are integrated with the plurality of truss members.
Abstract:
A submarine survey platform, including: a gasbag; a gas tube; a floater; an upper longitudinal plate; a lower longitudinal plate; diaphragm plates including upper openings, lower openings, and trapezoid openings disposed between the upper openings and the lower openings; and diagonal braces. The upper longitudinal plate includes a flat plate and a flanged plate. The lower longitudinal plate is a rectangular plate. The upper longitudinal plate pass through the upper openings, and the lower longitudinal plate pass through the lower openings. The diagonal braces and longitudinal stiffeners are disposed between every two adjacent diaphragm plates. Two diaphragm plates at two ends of the flat plate are provided with a lifting lug. The diagonal braces are symmetrically disposed and include outward braces and inward braces which are crossed with each other. Cross points of the upper/lower longitudinal plate with the diaphragm plates are support points of the upper/lower longitudinal plate.
Abstract:
A marking machine for sections of vessels, including: a marking device and a gantry. The gantry includes rail wheels, horizontal beams, and upright columns. The horizontal beams include an upper beam, middle beams, and lower beams. The marking device is disposed on the upper beam of the gantry. The marking device includes a trolley and a marking arm. The trolley hangs on the upper beam. The marking arm includes a plumbing arm, a swing arm, a first universal joint, a second universal joint, a first Z-shaped steering knuckle, a second Z-shaped steering knuckle, a telescopic arm, and a penholder. The plumbing arm is fixedly connected to the lower part of the trolley. The first universal joint is disposed on the plumbing arm. The first Z-shaped steering knuckle is connected to the first universal joint.

Abstract:
The present invention relates to a method, apparatus and system for accessing remote files, wherein the method for accessing remote files comprising the following steps: obtaining download operation information for downloading a file in an operational system server; redirecting the download operation to a file server with safety space; saving a real copy of the downloaded file in the safety space and enumerating a corresponding virtual copy in the safety space. In the present invention, local file operations are redirected to the network file operations of network file storage system by redirecting the download operation on the file in the operational system server to the file server instead of being saved in the local user terminal to realize the “Not to local” effect for the key file. Even when it is power-off and then restarted, the data will not be saved in the local user terminal to achieve an effect close to “physical-like isolation”, which solves the safety problems of the offline key file much better.
Abstract:
A method of automatically reducing stacked vias while minimizing voltage drop in a power network of an integrated circuit (IC) is provided. In this method, any feasible (i.e. other than connectivity-necessary and uncongested stacked vias) stacked vias of the power network can be virtually removed. If a target voltage drop of the power network is exceeded, then a measurement of the severity of at least a maximum voltage drop on the IC can be updated. After this updating, a set of voltage drop improvement stacked vias can be virtually returned to the power network. The steps of determining whether the target voltage drop is exceeded, updating the severity of the voltage drop at one or more hot spots, and virtually returning the set of additional stacked vias can be repeated until the target voltage drop is not exceeded.
Abstract:
A tool that a user may employ to assemble the components of a circuit in a floor plan design. The tool provides a user interface that displays the placement of blocks in a floor plan design, and the routing of wires among the blocks. When the designer moves the placement of a target block, the user interface automatically moves any adjacent blocks that would impede the movement of the target block and any block that would impede a block moved in response to the movement of the target block. The user interface may also respond to movement of a target block by showing how various features of the circuit will change as a result of the move. Thus, the user interface may show that moving one block closer to another block will create undesired wiring congestion in the circuit. The user interface also may show when moving a block will result in wiring connections that are too long to maintain a desired voltage level. The tool may also automatically move the placement of related blocks as a group, so that various attributes, such as a minimum distance between adjacent blocks, are maintained.
