The present invention provides a feed horn for use in an antenna assembly having a non-circular reflector. The feed horn is capable of transmitting and receiving circularly polarized signals. The feed horn includes a circular waveguide section for connection to a transmitter and receiver of the antenna assembly. A conical waveguide section is connected to an opposed end of the circular waveguide section for creating a smooth transition from the circular waveguide section to a non-circular corrug...

A steam turbine and steam turbine plant that can utilize a relatively higher reheated steam, such as about 1300 degrees Fahrenheit or higher, is provided. A steam turbine plant includes a steam generator generating high pressure steam and reheated steam, a high pressure turbine driven by the high pressure steam generated by the steam generator, and an intermediate pressure turbine driven by the reheated steam. A steam bleed line coupled with the high pressure turbine bleeds steam from the high p...

A photolithographic method of making an information storage device having different storage characteristics at a plurality of discrete memory locations thereon, comprises the steps of: (a) providing a substrate having a surface portion, said surface portion having a linking group coupled thereto or charge storage group coupled thereto, said linking group or charge storage group having a photocleavable protecting group thereon; (b) exposing at least one first discrete segment of said surface port...

An extension connector has a threaded end formed on a first end of the extension connector for connection with a threaded hole of a receptacle and a threaded hole adapted for connection with a threaded end of a ball linkage such that an angle adjustable cymbal stand is able to extend to any position for connection with a cymbal.

A computer-implemented method for analyzing problem statements. The method includes focusing the problem statement into an operation definition and then assigning a level indicator to the operation definition. The method further includes analyzing the problem statement based on the operational definition and the level indicator in a cost and time effective manner and without the need for an expert to customize an analysis schedule for each problem.

An electrical joint forming member is held between adjacent conductive members included in a semiconductor device fabricating apparatus to reduce electrical resistance between those conductive members. The electrical joint forming member includes an elastic member made of a titanium sheet (75 .mu.m thick, 2 mm wide) and having a surface covered with an aluminum layer (7 .mu.m thick), the aluminum layer being formed by joining an aluminum sheet to the surface of the titanium sheet by cold-roll bo...

A method for curing a layer of liquid coating applied to surfaces of a printed circuit board is disclosed. The method comprises exposing the layer of liquid coating to a curing agent; and manipulating the printed circuit board during the exposure so as to prevent the liquid coating from flowing from its applied location in response to gravitational forces. An apparatus for implementing the above method is also disclosed. The apparatus comprises a motorized assembly for rotating the printed circu...

A counterhoop formed by bonding a conventional flat shaped hoop with a resilient shell component comprised of a convex outer wall and a generally flat inner wall. The resilient begins as a liquid resin, which is poured into an annular mold. The metal counterhoop is inserted into the resin, and the cured resin is allowed to harden, forming a shell which is bonded to the counterhoop to create a unitary component. The inner and outer walls of the shell join at the top edge of the counterhoop, where...

A method for forecasting batch end conditions through their depiction as a multi-dimensional regions of uncertainty is disclosed. A visualization of the current condition of a continuous process and visualization of the simulated effect of user control moves are generated for a user. Volume visualization tools for viewing and querying intersecting solids in 3-dimensional space are utilized to perform the process visualization. Interactive tools for slicing multi-dimensional (>3) regions and d...

The differential pressure sensor is formed of a semiconductor substrate (1) which is thinned out in an inner region into a membrane (2) which may be impinged by pressure on both sides. Measurement resistances (3a to 3d) for detecting the differential pressure (P.sub.1 minus P.sub.2) are formed within the membrane (2), and compensation resistances (4) are formed on the carrier, which are connected to measurement resistances (3). The measurement resistances (3) are connected into a first measureme...
