摘要:
The present invention provides a chemical mechanical polishing composition for planarizing copper and a method for planarizing, or initiating the planarization of, copper using the composition. The chemical mechanical polishing composition includes an oxidizing agent and a copper (II) compound. The composition optionally includes one or more of the following compound types: a complexing agent; a corrosion inhibitor; an acid; and, an abrasive. In one embodiment, the oxidizing agent is hydrogen peroxide, ferric nitrate or an iodate. In another embodiment, the copper (II) compound is CuSO4. The chemical mechanical polishing method involves the step of polishing a copper layer using a composition that includes an oxidizing agent and a copper (II) compound. The composition is formed in a variety of ways. In one embodiment, it is formed by adding the copper (II) compound to a solution containing the oxidizing agent, and any included optional compound types, in deionized water. In another embodiment, it is formed by adding a solution containing the copper (II) compound in deionized water to a solution containing the oxidizing agent, and any included optional compound types, in deionized water.

A vertical connection apparatus for connecting a pipeline to a subsea structure comprises a guide funnel for controlling the position of the pipeline relative to the subsea structure; a moveable barrier and a attachment region for a drive mechanism; the moveable barrier is operable between an open position in which the pipeline can pass through the guide funnel and a closed position in which the barrier prevent the end of the pipeline passing through the end of the guide funnel. A tool with a drive mechanism can be attached between the pipeline and guide funnel to manipulate the pipeline into a connectable position. A clamp connector secures the connection between the pipeline and subsea structure conduit.

摘要:
Silicone composites subject to reticulation or reticulated, particularly for creating a coating or water-repellent and anti-adhesive film for flexible substrates such as paper or similar in the form of natural or synthetic polymer films. These compounds contain reticulating polyorganosiloxanes that have SiH units and unsaturated polyorganosiloxanes, preferably vinylated, suitable for reacting with the reticulating agent in an addition reaction and in the presence of platinum to form the reticulated anti-adhesive coating on the flexible substrate, plus at least one additive (D) to promote adhesion to it. A new liquid silicone compound can be applied without using a solvent, which is beneficial, that can be reticulated instantly to produce an anti-adhesive and/or water-repellent coating for the flexible substrate, giving very high quality reticulated silicone coatings, particularly in terms of sticking/adhering to the substrate, being harder to rub off and the anti-adhesion profile (sufficiently increase detaching force at high speed.
摘要:
An apparatus for connecting adjacent ends of first and second conduits including a frame assembly including a mounting point for mounting the end of the first conduit in a fixed position, a guide connected to the frame assembly and including first and second guide formations for receiving guide arms attached to the end of the second conduit and a moveable carrier mounted on the frame and including slots for engaging the guide arms. The carrier is moveable between a first position in which the slots align with the guide formations so that the guide arms can pass into the slots, and a second position in which the end of the second conduit is held against the end of the first conduit so as to allow a connection to be formed to secure the ends together.
摘要:
A method of determining a permittivity of a substance may include providing a probe having a planar end surface, providing a signal source and a signal receiver coupled to the probe, and physically contacting the substance with the planar end surface of the probe defining an interface. The method may further include measuring a reflection coefficient of the substance by at least transmitting a signal through the probe to the interface, receiving a reflected signal from the interface, and comparing the transmitted and reflected signals. The method may further include calculating the permittivity of the substance based upon the reflection coefficient.

A door closer comprises a piston cooperating with a rotating pinion. Upon rotation of the pinion in the door opening direction, the piston moves toward the second end of the housing forcing fluid from a second variable volume chamber through a passage to a first variable volume chamber and compressing a spring assembly for storing energy. The spring assembly urges the piston toward the first end of the housing for forcing fluid from the first variable volume chamber to the second variable volume chamber and rotating the pinion in the door closing direction. A controller controls the position of a valve in the passage based on the sensed angular position of a door and the position of the valve for determining the amount of hydraulic fluid flowing through the valve.

A self-adjusting door closer is disclosed. The door closer is self powered and includes a control unit to intelligently control a valve within the door closer to vary the operating characteristics of the door closer as needed. The controller includes a position sensor to determine a position of the door, and at least one input switch to enable user selection of at least one door closer parameter for an installed door closer. The control circuitry is operable to set the valve in response to the user selection of the door closer parameters, and the position of the door, in order to control force exerted by the door closer on the door. A generator can be provided to provide electricity to power the controller and store power to operate the controller.
