Metal-ceramic interfaces of enhanced strength are produced by positioning bodies of ceramic oxides and transition element metals or alloys containing such in abutting relationship, and heating in air at a temperature ranging from 500.degree. C. to just below the melting point of the metal of the metal body to join said bodies and then subsequently heat treating said joined bodies in a reducing atmosphere at a temperature in the range of 300.degree. C. to 1200.degree. C. to form intermetallic com...

A system and method for interactive design of user manipulable graphic elements. A computer has display and stored tasks wherein the appearance of graphic elements and methods for their manipulation are defined. Each graphic element is defined by at least one figure specification, one mask specification and one map specification. An interactive display editor program defines specifications of said graphic elements. An interactive program editor program defines programming data and methods associ...

Method for fracturing the interface between dental structures that have been secured together. The device comprises an ultrasonic tool for providing bi-directional movement of a preferred amplitude and frequency. The tool is applied against one of the dental structures at an acute angle with respect to a plane in which the interface between the dental structures lies.

An encoder interface for interfacing an encoder having a first part defining a first axis to a structure having a second part defining a second axis substantially parallel to the first axis includes a portion for translating the first part with respect to the second part in a direction transverse to the first axis and a portion for rigidly rotationally stabilizing the first part with respect to the second part against a rotation of the first part about the first axis induced by a translation of ...

The present invention is generally directed to improved methods, structures and systems for interfacing microfluidic devices with ancillary systems that are used in conjunction with such devices. These systems typically include control and monitoring systems for controlling the performance of the processes carried out within the device, e.g., controlling internal fluid transport and direction, monitoring and controlling environmental conditions and monitoring results of the processes performed, ...

A system for generating a set of graphical images based upon application of different graphical transfer functions to data of physical structures in a scene. The application of the different graphical transfer functions define graphical images of a single scene having different characteristics. A user can then review the images to select a desirable image, without having to define or know the graphical transfer function which generates the image. The system of the present invention generates a d...

A monolithic component for protection against over-currents liable to occur on a line in series with which is connected a detection resistor, comprises a first cathode-gate thyristor associated with an avalanche diode and a second anode-gate thyristor of the gate triggering type or forward breakover type, its breakover voltage being substantially equal to the avalanche voltage of the avalanche diode.

Provided are a method, system, and article of manufacture for assigning addresses for adaptor interfaces. An initial configuration assigning multiple local interfaces to one initial local address is maintained. For each local interface, a remote address of a remote interface on at least one remote device to which the local interface connects is received. The initial local address is used to identify the local interfaces assigned to the initial local address in response to receiving a same remote...

A process and apparatus for detecting changes in interface level between distinct materials within a container independent of any chemical or physical changes taking place within either or both of the distinct materials. Sensors are introduced into each of the materials and an additional sensor is placed across the interface, the output from each of the three sensors is transmitted to an adaptive detector device which combines these outputs by means of a control equation to give an emanating sig...

A method of making a facet coating for a semiconductor light emitting device, such as a semiconductor laser or the like, comprising the steps of depositing a thin layer of a reactive material on the cleaved facet to getter oxygen and other reactive contaminants therefrom, and controlling the thickness of the deposition to be sufficiently thick to react with an optimum amount of said contaminants but sufficiently thin in order that the reactive material is sufficiently consumed in the gettering p...
