Title: Process for separating hydrogen fluoride from its mixtures with 1,1,1-trifluoro-2-chloroethane
IPC: C07C17/38
Filed: 1992-04-09
Abstract: Separation of hydrogen fluoride (HF) from its mixtures with 1,1,1-trifluoro-2-chloroethane (F133a). By settling the mixture of HF and F133a at a temperature below 0 DEG C, there is obtained a lower organic phase which is poor in HF and an upper phase which is rich in HF. The latter can be directly recycled to the fluorination reactor or subjected to a distillation to separate the HF/F133a azeotrope at the head, which is sent back to the settler, and to recover practically pure HF at the base. By distillation of the lower phase, the HF/F133a azeotrope is separated at the head, which is sent back to the settler, and F133a is recovered at the base.

Title: Method of making contact for semiconductor device.
Inventor: ROEHL SIEGFRIED DR
IPC: H01L23/532
Filed: 1993-08-04
Abstract: A method of forming a capped and borderless contact of polysilicon on a body of a semiconductor material includes depositing a layer of undoped polysilicon on the surface of the body and forming an opening therethrough to the surface of the body. The side walls of the opening are then coated with a layer of silicon nitride and the opening is then filled with doped polysilicon which forms the contact. The doped and undoped polysilicon are heated in an oxidizing atmosphere to grow a layer of silicon dioxide thereon having a thicker portion over the doped polysilicon then over the undoped polysilicon. The silicon dioxide layer is etched to remove the thinner portion leaving the thicker portion over the doped polysilicon as a capping layer. The undoped polysilicon is then etched away and a layer of a dielectric material is deposited on the body and surrounding the doped polysilicon contact. <IMAGE>

Abstract: A vehicle state estimating apparatus
includes a slip-angle determining unit (40) which
determines a slip angle of a wheel of a vehicle. A
friction-coefficient determining unit (42) determines a
friction coefficient between a tire of the wheel and a
road. A tire characteristics unit (44) generates a
lateral force of the wheel from the slip angle and the
friction coefficient based on predetermined tire
characteristics. A vehicle-state estimating unit (46)
determines an estimated quantity of a state of motion of
the vehicle based on the lateral force output by the tire
characteristics unit. A vehicle-state observing unit (48)
detects an observed quantity for the estimated quantity
determined by the vehicle-state estimating unit. A
friction-coefficient correcting unit (50) corrects the
friction coefficient determined by the friction-coefficient
determining unit, based on a difference
between the observed quantity and the estimated quantity,
so that the lateral force from the tire characteristics
unit is corrected by the corrected friction coefficient.

Abstract: A multipole multiposition microwave switch system
 101  with a common redundancy is directed to a new and
innovative RF switch that enables the integration of a
plurality of high-power RF transmission line switches
into one mechanical assembly while giving the system an
ability to provide a redundant operation for each of the
high-power RF transmission line switches. The invention
combines the connectibility of, more particularly, three
or more single-pole-double-throw [SPDT] switches and one
single-pole-multiple-throw [SPMT] switch to form a single
unit of multiple-pole-(multiple plus one)-throw
[(N)P(N+1)T] multipole multiposition microwave switch
system  101  with a common redundancy. The multipole
multiposition microwave switch system  101  achieves the
great number of redundancy by having each of the
switching mechanisms, along with its input and output RF
connectors, parallelly, radially, and commonly connected
to the redundant RF connector  123 . Because each set of
the input and output connectors are commonly and
parallelly connected to the redundant connector  123 , the
number of switches, along with their input and output RF
connectors, which can be integrated with the redundant RF
connector  123  are not numerically or physically limited.
Therefore, this invention allows the packaging of any
variety of multiple-pole-(multiple plus one)-throw 
[(N)P(N+1)T] multipole multiposition microwave switch
system  101  with a common redundancy; such as 3P4T, 4P5T,
5P6T, 6P7T, 7T8P, and others with more switches.

Abstract: A method of preparing a surface for and forming a thin film
on a silicon substrate is disclosed. One
embodiment of his method comprises forming an oxidized silicon
layer (which may be a native oxide) on at least one region of
the substrate, and thermally annealing the substrate in a vacuum
while supplying a silicon-containing flux to the oxide surface,
thus removing the oxidized silicon layer. Preferably, the thin
film is formed immediately after removal of the oxidized silicon
layer. The silicon-containing flux is preferably insufficient
to deposit a silicon-containing layer on top of the oxidized
silicon layer, and yet sufficient to substantially inhibit an
SiO-forming reaction between the silicon substrate and the
oxidized silicon layer. The method of the invention allows for
growth or deposition of films which have exceptionally smooth
interfaces (less than 0.1 nm rms roughness) with the underlying
silicon substrate at temperatures less than 800°C, and is
ideally suited for deposition of ultrathin films having
thicknesses less than about 5 nm.
