Granted: 1992-06-02
Abstract: ABSTRACT OF THE DISCLOSURE        A lapping device for surface enhancement of bulk material including a treatment chamber which is closed gas-tight and is charged with an inert gas, at least one vibratory conveyor being arranged in the treatment chamber and means for creating motion between a lapping abrasive liquid and the goods on the conveyor to form a surface enhancement for the goods.  The arrangement for creating motion can be either abrasive nozzles for creating a jet of abrasive material directed onto the goods, the movement of the vibratory conveyor through a bath of the lapping abrasive or a combination of both.  The lapping device is particularly useful for pretreatment of bulk goods which are to be electro-plated.

Title: Angioplasty dilating guide wire
Inventor: WILLARD LLOYD K
IPC: A61M29/00
Filed: 1987-08-07
Granted: 1991-05-14
Abstract: ABSTRACT OF THE DISCLOSURE      A dilating guide wire for use in percutaneous transluminal angioplasty has a very small outside diameter which permits it to be used advantageously with a percutaneous transluminal coro-nary angioplasty (PTCA) catheter for treatment of very tight stenoses in the coronary arteries that cannot be treated by con-ventional PTCA catheters alone. The dilating guide wire is small enough to pass through the through lumen of the PTCA catheter and extend beyond the distal tip thereof for predi-lating the stenosis to open it sufficiently for subsequent crossing and dilation by the PTCA catheter.  According to a pre-ferred form of the invention, the dilating guide wire has a hollow core communicating to a small opening to the balloon area at the distal end, and venting to the atmosphere at the proximal end of the dilating guide wire, to serve as a vent for air displaced from the balloon as it is inflated with inflation fluid.  The small dimensions of the vent path in the core result in self-sealing of the vent with respect to the inflation fluid, due to the surface tension and capillary action of the inflation fluid attempting to move into the vent as teh balloon is pressurized.  According to another feature, a control handle is provided for selectively imparting an axial force to the balloon of the dilating guide wire to cause axial stretching thereof, thereby reducing its profile and facilitating withdrawal of the balloon area of the dilating guide wire back into the through lumen of the PTCA catheter.  Methods of treating stenoses using the dilating guide wire and a PTCA catheter are also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE A novel  apparatus  is provided herein for  sensing either motion or the presence of an object, or both, within a  detection  region.   That apparatus  includes  a  first emitting means for generating and emitting a first beam of energy towards the detection region and also towards a sensing region.  A second emitting means is provided for generating  and  emitting  a  second  beam  of  energy complementary to the first beam of energy.  Sensing means at a sensing region receive and sum the energies of the first and second beams of energy to produce a corresponding sensing signal having a constant signal portion and a time varying  signal  portion.    Filter means  coupled to  the sensing means block the constant signal portion of the sum and pass the time varying signal portion.  Detection means convert the time varying signal portion to a proportional detection signal indicative of either the motion or the object.  Modulating means are responsive to the detection signal for modulating one of the beams of energy to null the time varying signal portion.

Title: Error correction method using reed-solomon code
Inventor: OZAKI SHINYA
IPC: H03M13/27
Filed: 1988-02-02
Granted: 1992-02-11
Abstract: ABSTRACT OF THE DISCLOSURE           In an error correction method using Reed-Solomon code when the error correction is performed by using the result of the multiplication of a syndrome and an error location, another syndrome is added to thereby form a new syndrome.  By repetitively executing this procedure, the error vector is obtained by a small number or arithmetic operations relative to a known procedure, thereby performing error correction by the so-called erasure correction technique.  Then, by calculating another error vector using the first calculated error vector, the number of arithmetic operation times can be even further reduced.
