A data storage disk having a latent illuminance discrimination marker for determining whether the data storage disk is suitable for use in a disk drive. A light source illuminates the marker and the marker emits illuminance, preferably as phosphorescence. A detector detects the emitted illuminance, ...
Disclosed as endothelin converting enzyme inhibitors are the compounds of the formula
A connection component for making connections to a microelectronic element is made by providing leads on a surface of a polymeric layer and etching the polymeric layer to partially detach the leads from the polymeric layer, leaving a portion of each lead releasably connected to the polymeric layer b ...
A differential amplifier circuit for amplifying an input signal and for providing an output signal representative of the input signal includes first and second amplifier circuits, and first and second coupling circuits. The first and second amplifier circuits each include first and second transistor ...
The radial suction opening extends essentially completely around the air stream sucked in through the axial suction opening. The suction opening arrangement is arranged by an air guidance ring (13) opening in funnel-fashion at least in sections to the suction side by the design of an annular suction ...
This invention is directed to a method for synthesizing a carbonyl based compound under neat conditions comprising refluxing a metal carbonyl compound with an excess of neutral ligand to produce a first mixture; evaporating any excess neutral ligand from the first mixture to produce a second mixture ...
The present invention relates to electrochromic ploymeric solid films, manufacturing electrochromic devices using such solid films and processes for making such solid films and devices. The electrochromic polymeric solid films of the present invention exhibit beneficial properties and characteristic ...
The present invention, in one form, is an imaging system for generating images of an entire heart. In one embodiment, projection data is collected for a field of view containing only the heart so that the total detector size is reduced. The smaller detector allows the use of a plurality of source-de ...
There is provided a process for the selective production of para-xylene which comprises reacting toluene with methanol in the presence of a catalyst comprising a porous crystalline material having a Diffusion Parameter for 2,2 dimethylbutane of about 0.1-15 sec
