Abstract: An automatic leveling type maintenance platform for a high-temperature gas cooled reactor is provided. A floating plate is automatically leveled by using a leveling liquid. During leveling, only a water driving assembly needs to be controlled to drive a housing to be close to an inner bottom surface of a liquid storage container. A sliding block assembly and a lifting guide mechanism are controlled to be locked and fixed after the floating plate is leveled. The floating plate can allow for automatic and rapid leveling and locking operation. Thus, complex and time-consuming fine adjustment control does not need to be performed. Also, when the platform is used in a spherical top cap of a pressure vessel of the reactor for a maintenance operation, then support legs of a support assembly do not need to have telescopic motion.

Abstract: An automatic leveling type maintenance platform for a high-temperature gas cooled reactor is provided. A floating plate is automatically leveled by using a leveling liquid, and during leveling, only a water driving assembly needs to be controlled to drive a housing to be close to an inner bottom surface of a liquid storage groove, and a sliding block assembly and a lifting guide mechanism are controlled to be locked and fixed after the floating plate is leveled. In this way, complex and time-consuming fine adjustment control does not need to be performed, and the floating plate can implement automatic and rapid leveling and locking operation, so that a leveling effect is better. When the maintenance platform is used in a spherical top cap of a pressure vessel of the high-temperature gas cooled reactor for maintenance operation, support legs of a support assembly do not need to perform telescopic motion.

Abstract: A system for generating predictions associated with interdependence detection between a plurality of data objects, each data object of the plurality of data objects corresponding to an entity name, the system processing, using a natural language processing engine, text strings to extract entity names associated with each of the text string; processing, using a machine learning engine, the text strings to extract estimated economic relationships identified between at least two different entity names. The estimated economic relationships are aggregated for each pair of entity names to establish of potential interdependence between the pair of entity names. An output data structure is generated based at least on the aggregated estimated economic relationships.

Abstract: Provided is an apparatus containing, as a cathode catalyst, a metal oxide/carbon catalyst composition. The metal oxide/carbon catalyst composition includes 40 to 95 wt % porous Mn—Co spinel oxide nanoparticles of the formula MnxCo3-xO4. The nanoparticles have an octahedral morphology, an average particle size of 5-100 nm, and average pore sizes of 1-5 nm (where x is the atomic fraction of manganese and 3-x is the atomic fraction of cobalt). The metal oxide nanoparticles are supported on a carbon substrate that contains at least 96 atomic % carbon.

A first current limiting circuit (6) provides protection against a short circuit or other extraneous load conditions, while a second current limiting circuit, using a trace on a PCB as a sensing element, is programmable on the basis of a time constant and a current level.

Abstract: A field emission cathode and a method for manufacturing the same are disclosed. In the present invention, the carbon nanotube is coated with an amorphous coating material so that the above-mentioned field emission cathode resists oxidization in a high electrical field and the structure thereof can be protected. Additionally, the field emission cathode can exhibit field emission performance in a low electrical field, and generate stable current as the electrical field increases so that the efficiency and stability of the field emission current can be enhanced.

Abstract: A method of fabricating an ESD protection circuit without salicide formation is described. First, isolation regions and gate structures are formed on a semiconductor substrate, then device regions and ESD circuit regions are then defined. Next, a first dielectric layer is deposited the over entire semiconductor substrate, and heavily doped source/drain regions are formed in ESD protection circuit region. Next, a second dielectric layer and the first dielectric layer of NMOS areas are etched to form spacers on the sidewalls of the gate structures. Then, N.sup.+ /P.sup.+ ion implantation are performed to form heavily doped source/drain regions of NMOS and PMOS, respectively. Finally, salicide process is performed to form silicide over the exposed surface of the gate, source/drain regions in the NMOS and PMOS active device regions.
