Abstract: A metal grid within a trench isolation structure on the back side of an image sensor is coupled to a contact pad so that a voltage on the metal grid is continuously variable with a voltage on the contact pad. One or more conductive structures directly couple the metal grid to a contact pad. The conductive structures may bypass a front side of the image sensor. A bias voltage on the metal grid may be varied through the contact pad whereby a trade-off between reducing cross-talk and increasing quantum efficiency may be adjusted dynamically in accordance with the application of the image sensor, its environment of use, or its mode of operation.

Abstract: The rainmaking device includes a first pipe member, a connection member, and a second pipe member. The first pipe member is installed adjacent to a warm water source. The first pipe member has an intake facing the warm water source. A number of blowers configured around the intake. The connection member is connected between the first and second pipe members. The second pipe member has a cone shape whose aperture gradually decreases upward. Through the blowers, the first and second pipe members, wet air above the warm water source of 22-25 degrees is drawn up to a high altitude. Tiny ice crystals attract surrounding water vapor and become larger and heavier. They will then drop as rain when the buoyance can no longer support them. The latent heat released would power the convection of surrounding air so that a chain reaction may be triggered, and cumulonimbus would become rain and fall.

Abstract: A manufacturing method of a colored high-strength fiber has a preparation step, a dyeing step and a post-processing step. In the preparation step: a high-strength fiber substrate is surface-treated by solvent, and a surface of the high-strength fiber substrate is fractured, such that a surface-treated substrate is manufactured. In the dyeing step: the surface-treated substrate is plated, wherein multiple metal ions are combined with a surface of the surface-treated substrate, such that a dyed substrate is manufactured. In the post-processing step: the dyed substrate is surface-cleaned to remove remaining agents caused by the dyeing step, such that the colored high-strength fiber is manufactured.

Abstract: A ship hull structure includes a main hull and a movable rearbody having an engine and a propeller. The movable rearbody is located at a lower side of a stern of the main hull, connected with an aft of the main hull to form an integral unit by a hinge linking device allowing the rearbody to pivot up and down. By a block, a crane or a winch and through a chain or a hanging wire, a pivoting angle of the movable rearbody with respect to the main hull can be adjusted and controlled. A bottom of the hull can be provided with at least one, usually plural, air cushion recess, which is filled with pressurized air to reduce a viscous force between a bottom of the ship and water.

A bottom of the hull can be provided with at least one, usually plural, air cushion recess, which is filled with pressurized air to reduce a viscous force between a bottom of the ship and water. When a ship of this kind of structure is sailing, the rearbody can be lifted up by the block or the winch, allowing part of the propeller to be separated from a water surface to reduce resistance in the water that the engine can achieve a required rotational speed (RPM) in a short time.

Abstract: A method for making a wood-like plate by using a mold structure comprises the steps of pushing a wood texture layer into the mold opening of the slit to enclosing the material feeding mold seat; guiding foaming material into the feeding opening of the material feeding mold seat; and forwarding the wood texture layer to encloses the shaped foam plate tightly adhered on the wood texture layer. By the expanding force of the foaming material, the wood texture layer will resist against the inner surface of the slit in an inner section of the material receiving mold seat since the length of the material feeding mold seat is shorter than the material receiving mold seat. The material is foamed as a wood-like plate along the shaping channel and then enclosed by the wood texture layer as a wood like plate. A device for processing the method is also enclosed.

Abstract: A device for making a wood-like plate comprises a material receiving mold seat and a material feeding mold seat. A shaping channel is in an inner side of a material receiving mold seat. A material feeding mold seat is located in mold openings of the material receiving mold seat. A plurality of feeding openings is formed longitudinally along the material feeding mold seat for being filled with foaming material. A slit is formed as the material feeding mold seat being located in the material receiving mold seat. A wood texture layer enclosing material feeding mold seat. Heated foaming material is fed into the feeding openings of the material feeding mold seat and outputted from the feeding openings at another side so as to form a shape like the shaping channel. The wood texture layer moves forwards and then encloses the shaped foam plate so as to form a wood-like plate.

Abstract: This invention discloses a novel ship design especially suitable for ocean-going merchant vessels and oil tankers. A ship is rendered into two or more independent ship bodies, and these separate ship bodies are joined together by means of hinge; thus the name sectioned ship. In one embodiment of the invention a sectioned ship comprises a fore ship body and an aft ship body, and, by means of a hinge means located in the middle part, i.e., the adjoining surface of said two ship bodies, the two ship bodies are vertically pivotably joined to form a ship. In another embodiment of the invention, a sectioned ship comprises a fore ship body, an aft ship body, and at least one intermediate ship body, and by means of two hinge means located at the two ends of the intermediate ship body these ship bodies are vertically pivotably connected to form a single body.

Abstract: A cross-shaped float platform for use at sea watching and fishing, including 4 long trunk buoys having a plurality of columns connected to form in a cross-shaped float, a structural suspension frame mounted on the columns, decks suspendedly disposed on the lower part of the suspension frame at the middle part of the columns and stretching between the two sides (port and starboard) and along the longitudinal direction, a central connecting member pivotedly connected to each of the buoys, reinforcing elements provided at each connecting portion of the buoys, and a sun canopy mounted on the suspension frame for covering the deck. The cross-shaped fishing float platform can be separated out from the connecting member and folded up to form a dual composite float to facilitate its entry or leave from small harbors or ports.

Abstract: A hydrofoil craft according to the invention is provided on the bottom of the hull with at least one, usually several, air cushion recesses arranged along the middle of the bottom in a fore-and-aft direction. The air cushion recesses each forms a groove having the upwardly indented bottom, the upper wall front end, to be deeper and becoming shallower toward the rear end and resembling a triangle or sector in shape when viewed in a longitudinal section and generally to be a rectangle in shape when viewed in a plane. The angle from the shallowest end of the air cushion recess to the deepest end is within 1.degree. to 30.degree. and the two side walls on the sides of the bulwarks of the recess extend a little to the lower parts of the fore-and-aft end walls. The hydrofoils are mounted across the lower parts of the air cushion recesses and are close to the air cushion recesses.
