Patent EP-0341980-A3 (EP)
IPC: H02M7/06
Filed: 1989-05-09
Abstract: Voltage regulation of a DC electrical power 
source having a generator (10) with an exciter field coil 
for producing an AC output voltage which is rectified to 
produce a DC output voltage, is accomplished by producing 
voltage signals proportional to the AC output voltage of 
the generator and the current in the generator exciter 
field winding, and combining these signals to produce a 
control signal. An additional voltage signal proportional 
to the DC output voltage of the power source is compared 
to a DC reference voltage signal to produce a trim error 
voltage signal. The trim error voltage signal is combined 
with an AC reference signal to produce an additional 
control signal. These control signals are compared and 
the result of that comparison is used to control the 
current in the generator exciter field winding.

IPC: G02B27/28
Filed: 1989-05-12
Abstract: Apparatus for isolating optical feedback in a laser 
interferometer having a laser light source (12) from 
which a linear polarised outgoing laser beam (28) of 
certain polarisation orientation is derived. The 
interferometer also redirects the outgoing laser beam to 
form a return laser beam (29) directed to a receiver 
(13). The outgoing and the return laser beams are 
physically close and are substantially parallel. The 
linearly polarised outgoing laser beam is converted to 
circular polarisation. A portion of the circularly 
polarised return laser beam directed toward the laser 
light source is converted back to linear polarisation 
with polarisation orientation orthogonal to the 
polarisation orientation of the outgoing laser beam. A 
portion of the circularly polarised return laser beam 
directed toward the receiver converted back to linear 
polarisation with polarisation orientation being 
substantially the same as the polarisation orientation 
of the outgoing laser beam. The portion of the return 
laser beam with polarisation orientation orthogonal to 
the polarisation orientation of the outgoing laser beam 
is directed away from the laser light source, and the 
portion of the return laser beam with polarisation 
orientation of the outgoing laser beam is directed 
toward the receiver.

Anwendung nicht ausreichend bioverfügbar sind, wird die orale 
Lipidarzneiform aus der Kombination einer halbfesten, lipophilen 
Komponente mit einer festen, wasserlöslichen Komponente

als auch biochemische Aspekte der oralen Lipidarzneiform 
ergeben Verbesserungen für die Resorption oral nicht 
ausreichend bioverfügbarer Arzneistoffe.

Patent EP-0396307-A3 (EP)
IPC: C03C3/062
Filed: 1990-04-25
Abstract: This invention is directed to a process of producing 
semiconductor devices which involves deposition of protective glass 
layers by a particle beam technique from targets of phosphosilicate 
glass, as well as a process for production of such targets. The 
phosphosilicate glass containing 1-15 mole percent P₂O₅ is produced by 
a sol/gel technique which involves mixing of a fumed silica, with a 
surface area of 50-400 m²/g, preferably about 200 m²/g, with 
phosphoric acid and water to form a sol with 20-55 wt. % silica, 
allowing it to gel, drying at ambient conditions, dehydrating at about 
650°C in an atmosphere of an inert gas and chlorine and fluorine 
containing gases, heating up at a certain rate of from 100 to 180°C 
per hour to a peak sintering temperature below 1200°C and cooling so 
as to produce amorphous and transparent glass suitable for use as a 
target. The glass layers are highly advantageous as encapsulating 
layers, diffusion barrier layers, etc., especially for optical type 
and semiconductor devices. Production of the phosphosilicate glass by 
the sol/gel technique is highly advantageous over the conventional 
melting technique, being faster and much less expensive than the 
latter.

Title: A nozzle of a fluid dispensing device
Inventor: WEST DAVID B
IPC: B41J2/055
Filed: 1993-09-15
Abstract: A nozzle for an ink-jet printer is provided having a gradually converging inner diameter leading to an orifice less than 15 microns in diameter and having an outer nozzle diameter proximate the orifice at least as great as the outer diameter at other points along the nozzle. The nozzle is produced by heating a vitreous tube while rotating it, until a portion of the tube is sufficiently viscous to cause the inner diameter to converge at an angle between 5 and 25 degrees with respect to the axis of symmetry of the tube, and until the inner diameter is less than a selected orifice diameter. The gradual taper is achieved without drawing or pulling the tube and it facilitates achieving a desired orifice dimension during removal of a portion of the tube having an inner diameter less than the selected orifice diameter. The extremely small orifice size enables an ink-jet printer to deposit droplets of ink sufficiently small to make photographic-quality gray scale and color images. <IMAGE>
