Granted: 1995-01-17
Abstract: An induction heating apparatus has a coil or coils which can be opened without using electrical contacts.  One continuous electric current passageway is formed by a first coil section, a second coil section, a first connecting conductor and a second connecting conductor.  By feeding electric power to this electric current passageway and passing an object through a space at the central portion of the coil sections, the object is induction heated.  A gap is provided between the first connecting conductor and the second connecting conductor, or the respective connecting conductors can be opened and closed relative to one another to vary the size of the space therebetween.  The object to be heated is carried into the space at the central portion of the coil and is carried out therefrom through the gap or the space between the conductors.

Title: Method for forming interconnect structures for integrated circuits
Inventor: JOLLY GURVINDER
IPC: H01L21/768
Filed: 1992-11-12
Granted: 1998-02-10
Abstract: A method is provided for forming interconnect structures for ULSI integrated circuits.  Preferably, a barrier layer of a conductive material which forms a seed layer for metal deposition is provided selectively on the sidewalls and bottom of interconnect trenches defined in a dielectric layer, and a conformal layer of metal is selectively deposited on the barrier layer within the interconnect trench.  Advantageously, the metal layer forming interconnect comprises a layer of copper which is deposited by chemical vapour deposition from an organo-metallic precursor at low temperature.  Etching back and planarization of the barrier layer and the metal layer is accomplished by chemical mechanical polishing.  Second and subsequent levels of metallization are provided by repeating the process steps, as required, to provide another dielectric layer defining interconnect trenches, selectively lining the trenches with a conformal barrier layer and then filling the trenches with selective deposition of a conformal conductive layer of metal, with planarization of the resulting conformal layers by chemical mechanical polishing.  Preferably, via holes forming contacts to underlying device structures are filled with copper or tungsten.

Abstract: The top storage tank end wall of a down-fired water heater has a first circumferentially spaced series of circular openings formed therethrough  and centered  about the  tank  axis,  and a  second circumferentially spaced series of circular openings centered about the tank axis and spaced radially outwardly of the first series of openings.      Vertically   disposed  within   the   tank   is   a circumferentially spaced series of hollow U-tube immersion heating members each having a first open upper end secured to one of the first series of openings, and a second open upper end secured to one of the second series of openings.   Shot-type fuel burners extend downwardly into the second open upper tube ends and are supplied with gaseous fuel via a manifold ring positioned atop the water heater.   Hot combustion gases from the burners are drawn through  the U-tubes  by  a  draft  inducer  fan having  an  inlet connected to the first open upper ends of the tubes.   In an alternate embodiment of the water heater, air-driven power fuel burners are connected to the first open upper tube ends and are supplied with driving air through a manifold structure connected to the outlet of a supply air blower.  Combustion gases forced out the second tube ends are collected in an exhaust manifold structure for venting to atmosphere.

Abstract: A multipurpose arena has a platform providing a performing, playing or exhibition area which can be raised or lowered to allow for different configurations of banked seating. The raising and lowering is achieved by displacement of air in or out of an air vessel formed beneath the platform, either by a hull floating in a well which can be emptied of water by air pressure or scuttled, or by a skirt depending from the platform and sealed to underlying structure. If a skirt is used, space can be reclaimed within a structure inside the skirt which provides a reaction surface for the air pressure. The skirt may be sealed to the underlying structure by a water seal in a trough, or by sealing the lower edge of a telescoping skirt to the structure.

Abstract: A valve housing has a chamber formed therewithin, and an inlet and an outlet for accommodating fluid flow through the chamber along a given flow path. The housing further confines a free ball therein, and hydraulic-fluid filed compartments with flexible walls.  Intermediate the inlet and outlet, the housing has a valve seat formed.  Fluid pressure in the chamber causes one compartment to collapse and the flexible wall of the other to expand.  The expanding wall, and capturing fluid flow, moves the ball to the seat to halt flow through the chamber, after an initial period of free flow.  The method comprises providing the chambered housing, disposing the ball in the chamber, communicating the inlet with a pump outlet, and confining the flexible-walled compartments in the chamber.

Abstract: Network Distributed Caches ("NDCs") (50) permit accessing a named dataset stored at an NDC server terminator site (22) in response to a request submitted to an NDC client terminator site (24) by a client workstation (42). In accessing the dataset, the NDCs (50) form an NDC data conduit (62) that provides an active virtual circuit ("AVC") from the NDC client site (24) through intermediate NDC sites (26B, 26A) to the NDC server site (22). Through the AVC provided by the conduit (62), the NDC sites (22, 26A and 26B) project an image of the requested portion of the named dataset into the NDC client site (24). The NDCs (50) maintain absolute consistency between the source dataset and its projections at all NDC client terminator sites (24, 204B and 206) at which client workstations access the dataset. Channels (116) in each NDC (50) accumulate profiling data from the re-quests to access the dataset for which they have been claimed. The NDCs (50) use the profile data stored in channels (116) to an-ticipate future requests.

Abstract: The invention provides an anti-skid controller capable of correctly executing ABS control by accurately estimating a road surface µ without using additional sensors .      Each wheel speed is detected, and acceleration of the vehicle body in a case where a wheel speed difference between front and rear wheels exceeds a specified value is determined. In this case, by using a change rate within a specified period of time with respect to a wheel speed of one in which wheel speed changing is small as the acceleration, a road surface µ corresponding to the acceleration is determined. Correc-tions regarding turning, bad road travelling, road surface changing, etc. can be carried out, by determining a lateral G based on a speed difference between left and right wheels.

Granted: 2010-11-09
Abstract: The common tree pathogen Chondrostereum purpureum is a known agent for effective biological control of so-called weed trees, e.g. red alder (Alnus rubra Bong). However, the commercial production and application of C. purpureum as a biological control has been hindered by the lack of durable and easily produced reproductive structures (spores) and the fragile nature of the fungus mycelium. In accordance with the present invention, a refrigeration storable preparation of the fungus C. purpureum includes a culture medium containing 90 - 95% by weight finely powdered inert material, approximately 3 - 10% by weight carbohydrates, approximately 0.1 - 0.3% by weight of a nitrogen source capable of providing approximately 0.01 - 0.03% by weight nitrogen; and trace amounts of a vitamin, preferably thiamine; sufficient water to establish and promote fungus growth while avoiding free moisture; and live mycelium of the fungus Chondrostereum purpureum. Such a preparation can be packaged and stored for up to one year. When mixed with a liquid carrier such as water, the product can be applied to weed trees.
