U9-90-033 A process for forming a thin film on a surface of a semiconductor device. The process involves formation of a silicon dioxide film by plasma enhanced thermal oxidation, employing a mixture of ozone and oxygen which are generated separately from the reactor chamber in a volume ratio of about 1-10/1, preferably about 5-7/1, at a temperature generally below 440.degree.C, preferably about 35...

2092075 9207871 PCTABS00013 Described herein are oligopeptides useful to inhibit HIV replication in virally infected individuals. In a preferred embodiment of the invention, the oligopeptide is a D-arginine nonamer having N- and C-terminal protecting groups, which, at a 5 .mu.m concentration, exhibits greater than 95 % inhibition of HIV replication, in a standard assay.

DESCRIPTIVE Carbon-containing composite material part protected against oxidation and its production process. The process consists of forming a fibrous preform or blank of the part by superimposing layers of carbon-containing fibres (12), the fibres of each layer being parallel to one another and the fibres of the N outermost layers being oriented in the same plane in accordance with a first or a ...

A detachable waistband for a garment consisting of a first band which matingly engages a second band. Each band is formed of two parallel elongate strips of conjoined material. Each band has an exterior surface, a first end, a second end, and an interior surface accessible through a flap-like opening positioned intermediate the first end and the second end and extending for substantially the lengt...

A cathode-ray tube includes a face plate having a light transmittance of at most 50% and a reflectivity reduction film formed on the external surface of the face plate to reduce reflectivity of an external light. The reflectivity reduction film is a low refraction index layer formed by using a coating liquid obtained by dispersing and mixing magnesium fluoride superfine particles to a base coating...

A fabric light control window covering in which fabric vanes 10a are adhesively bonded between two sheer fabric sheets 72,96 such that relative movement between the sheer fabric sheets in a direction perpendicular to the longitudinal direction of the fabric vanes changes the angle of the fabric vanes and, thus, controls the amount of light admitted through the shade. The vanes are bonded to the sh...

A weight sensing apparatus particularly, but not exclusively, for weighing tracked vehicles, comprises a beam (20) supported on first and second support means (23,24), at least one strain gauge (25,26) being positioned between the support means (23,24) and being spaced from the support means and an applied load (L), by a distance equal to, or closer than, a distance d max., where d max. is the thi...

The semi-automatic bevelling-heading machine makes it possible to prepare the surfaces of the edges 10 of the metal sheets 3 to weld with repeatable precision and consists, essentially, of a base 2 supporting the sheet 3, means 4 which hold and stably block the sheet 3 on the support table 5 of the base 2 and a pair of cutting tools 6, 11 with axes of rotation inclined and driven by respective mot...

Employs an automatic system continuously controllable by a computer, which, by means of a separator 1, takes the cardboard from the stack and places it on an oscillating adjustment idler 3. The cardboard, with the front edge coated with glue from a device 11, passes into alignment device 14 with inclined rolls which introduces it to shaping. The cardboard traverses the pair of rollers with a squar...

In wooden window frames formed by casing strips 1 and wing strips 2, 2e, at least one side of the wing is made up of two strips 2a, 2c parallel with an insertion slot 2d for the glass pane 3. After insertion of the pane 3, the two strips 2a, 2c are united by the section in plastic or metal material 6, applied by means of screws 7, 8, fitted in turn with pressure screws 5 acting by means of the sec...
