Title: Optical waveguide fiber and methods of forming an optical waveguide fiber and an optical waveguide preform
Inventor: BLANKANSHIP MICHAEL G
IPC: C03B37/018
Filed: 1982-03-30
Granted: 1989-03-14
Abstract: In the application of the single mode optical waveguide fibre such as gyroscopes and sensor, this fibre comprises a transparent core with a transparent cladding material of lower refractive index which includes on asymmetry that induces briefringence in the core.  The fibre preferably comprises an oblong cross section core which has a different thermal coefficient between an oblong inner cladding of a high purity glass layer and an outer circular cross section of cladding layer of stress cladding glass.  The fibre may be produced by flame hydrolysis where the core and inner cladding is collapsed to form an oblong preform which is then clad with a circular outer cladding alternatively.  The outer cladding may be a preformed glass tube.

Granted: 1989-10-27
Abstract: A chopper control system includes a chopper appts. in which a power source voltage is periodically chopped to be converted for driving a motor unit.  An integrated value of the chopper power during the conduction period of the chopper appts. is calculated. The chopper appts. is cut out when the integrated value reaches a predetermined value in order to turn on the chopper gate, a set pulse can be applied to the set input of a flip-flop.  The product of a voltage and a current are calculated at a multiplier.  The product obtained is intergrated at an integrator.  An instruction power is applied to the comparator so that, when it equals the product, the flip-flop is reset.

Title: Apparatus for imaging fluid flow
Inventor: WEARY PATRICS W
IPC: G01R33/567
Filed: 1986-06-14
Granted: 1989-05-31
Abstract: The living tissue is positioned in a substantially homogeneous magnetic field.  A region of the living tissue is determined such that the direction of arterial flow is substantially transverse to the plane of this region.  The propogation delay from the start of a cardiac cycle, marked by a contraction of the heart, to the occurrence of fast arterial flow in the region to be imaged is calculated.  A bolus of arterial flow within the region is before the fast flow reaches the artery within the region.  After a predetermined time period a second bolus of arterial flow is excited in the region such that the velocity of the flow throughout the time period remains substantially constant.

Title: Semiconductor deivce separation oxidation method
Inventor: JANG SONG-NAM
IPC: H01L21/76
Filed: 1990-11-20
Granted: 1993-08-18
Abstract: The method for forming a device-isolating oxide film  of  the semiconductor device comprises (a) coating a first oxide  film,  a polysilicon layer and a second oxide film on  the  single  crystal silicon substrate, (b) selectively etching the second  oxide  film and the polysilicon layer to form a window, (c) ion-implanting  an impurity through the window, and coating a nitride film and a BPSG film on the whole surface, (d) over-etching  the  BPSG  film,  and selectively removing the nitride film except the  device-isolating region, (e) removing the residual BPSG film, the second oxide film and the polysilicon layer, and (f) removing the nitride film.
