An assembly for High-Pressure High-Temperature (HPHT) processing comprising a can, a cap, a meltable sealant and sealant barrier, and a superhard mixture comprising superhard particles. The superhard particles may be positioned adjacent a substrate of cemented metal carbide. The can and cap contain the superhard mixture with the sealant barrier positioned within the assembly so as to be intermediate the sealant and at least a portion of the mixture, thereby preventing the sealant from coming in contact with the mixture during processing. The assembly is placed within a vacuum chamber and heated to a temperature sufficient to cleanse the assembly and then melt the sealant providing a hermetic seal for the assembly in preparation for further HPHT processing.

The present invention provides a removable vena cava filter for capturing thrombi in a blood vessel. The filter comprises a plurality of primary struts having first ends attached together along a longitudinal axis.

A grilling device includes an oven section having an outer wall with opposing side portions and an encircling body portion extending therebetween. The body portion has an access opening and the grilling device includes a lid that selectively covers the access opening by means of a handle attached thereto. The grilling device also includes opposing hinge elements connected to opposite sides of the lid and to the side portions of the outer wall, as opposed to the encircling body portion. In particular, the hinge elements are connected to respective rear areas of the side portions. Accordingly, the path of opening the lid has a different shape or curvature and thereby positions the handle substantially lower than if the hinge elements were connected to the body portion adjacent to the access opening. The opposing side portions have a substantially oval shape and the hinge elements have an elongated configuration.

Techniques are provided for combining searching and browsing into a single interface. The topology and content of a document collection or web site is determined and user information need keywords are determined. Relevant documents are identified using search techniques and the relevant document paths determined. The relevant document paths are analyzed using information scent to generate information scent values for the relevant document paths. A display attribute of the associated connection or link is then synthesized based on the information scent, the keywords and the document. The process repeats for each new document or web page.

The invention discloses a road tunnel intercommunication type longitudinal ventilation mode. The road tunnel intercommunication type longitudinal ventilation mode is characterized in that: an underground fan room and a connection ventilation duct are arranged at an appropriate position between two adjacent tunnels; the underground fan rooms are used for installing ventilation fans; the connection ventilation ducts are used for connecting the air flow of two tunnels; the automobile tail gas, which is generated in sections from the underground fan rooms to outlets, of pure uphill tunnels or uphill-major tunnels (uphill tunnels for short) is diluted by using cleaner air in pure downhill tunnels or downhill-major tunnels (downhill tunnels for short); and the polluted air, which is generated in sections from inlets to the underground fan rooms, of the uphill tunnels is discharged through the outlets of the downhill tunnels. By adoption of the road tunnel intercommunication type longitudinal ventilation mode, ventilation equipment can be reduced, ventilation shafts, inclined shafts or electrostatic dust removal stations are eliminated, and ventilation power consumption in daily operation is low, so that civil engineering cost and operation cost are reduced.

The invention provides a structure of a heterogeneous gate tunneling transistor of an under-gate process and a forming method of the heterogeneous gate tunneling transistor. The heterogeneous gate tunneling transistor comprises a substrate, a channel region, a source region, a drain region and a gate stack, wherein the channel region is formed in the substrate; the source region and the drain region are arranged on the two sides of the channel region; the doping types of the source region and the drain region are reverse; the gate stack is formed on the channel region and comprises a gate dielectric layer, a first gate electrode, a second gate electrode, a first vacuum side wall and a second vacuum side wall; the first gate electrode and the second gate electrode are formed on the gate dielectric layer and have different work functions; and the first vacuum side wall and the second vacuum side wall are formed on the two sides of the first gate electrode and the second gate electrode. Since the vacuum side wall from the gate to the drain region is introduced, the control of the gate over the drain region is weakened, and the gate-drain capacitance is reduced; a certain distance which can be accurately controlled exists between the gate stack and the drain region of a device, so that a tunneling potential barrier path is increased, and a double-pole window is expanded; and the energy band distribution of the channel region is modulated by a work function structure of the transverse heterogeneous gate, so that the sub-threshold slope of a transistor is obviously reduced, the driving current is increased and the performance of the device is enhanced.

Proposed is an illumination device (1), comprising a semiconductor light source (10) for generating light, a primary optical system (20) for feeding the light to a secondary optical system (30), which is provided for radiating the light and for achieving a desired radiation pattern. The semiconductor light source may comprise LEDs and / or Laser- Diodes. The primary optical system comprises a light-guide with a mirrored end-face (24) and an out-coupling structure (25) for directing light into the secondary optical system. The mirrored end-face optically folds the light-guide, effectively extending the length over which the light is advantageously homogenized inside the light guide. Furthermore, optically folding the light-guide makes more economical use of the space inside the secondary optical system. This is especially advantageous when designing an LED based retrofit for existing form factors of halogen based illumination devices.
