Title: Beam deflection method and apparatus for  sector scan ultrasound imaging systems
Inventor: HAYAKAWA YOSHIHIRO
IPC: G01N29/26
Filed: 1979-11-13
Granted: 1982-08-24
Abstract: ABSTRACT OF THE DISCLOSURE    Beam deflection delay time data of (L x M) data bits are stored in a read-only memory from which each datum is retrieved successively when the ultrasound beam is deflected to a given angle and repeatedly accumu-lated in a digital adder through a latching circuit connected between the output and input of the adder, where L is the number of discrete steps of deflection angle and M is a binary number representing the total delay time of piezoelectric transducers.  The successively latched data is distributed to respective programmable counters for presetting the count values thereof to store therein respective delay time data.  High frequency count pulses are supplied -to the counters after the latter has been preset for delivery of carry outputs to the associated piezoelectric transducers.  seam convergence delay time data is also stored in a second memory from which each datum is retrieved for each transducer element and accumulated so that a tapered configuration of binary differential numbers is created and added to -the beam deflection delay time data for converging the ultrasound beam.

Abstract: Abstract of the Disclosure A parallel encoded priority apparatus, and method of operation for use in data processing systems having a number of units. Each of the units within the priority configuration includes a parallel encoded priority circuit. Each of the parallelpriority circuits are interconnected by a common encoded parallel priority bus. The encoded parallel priority bus carries parallel priority signals indicating the priority level of any unit requesting access. If a unit requesting access has a lower priority than indicated on the parallel priority bus, that requesting unit is inhibited from obtaining access. If a requesting unit has higher priority than the signals on the parallel priority bus, that unit in turn causes the priority bus to be switched to the higher priority level. After the signals on the priority bus are switched to a higher priority level, any requests of a lower priority unit will not be honored.

Abstract: METHOD FOR FORMING GLASS CONTAINERS          ABSTRACT OF THE DISCLOSURE         Method for forming glass containers by the blow and blow process in which a parison mold having a plurality of cavities is centrally positioned relative to a pair of blow molds having a plurality of cavities.  The parisons are formed with their necks down in the parison mold from a charge of glass delivered to each cavity. Vacuum is applied to the neck area of the mold to form the finish portion of the container.          A neck pin is pulled and air under pressure is fed to the interior of the area from which the neck pin is drawn to expand the glass within the parison mold at a continuous rate until the glass within the parison mold comes in contact with a baffle which closes the upper end of the parison mold.  The parison mold is then opened and the parisons are transferred alternately from the parison mold to the blow molds where they are expanded into final shape.  During the transfer of the parisons from the parison mold to the blow mold, air under pressure is maintained within the hollow interior of the pari-son.  The parison transfer is carried out by the neck molds with parison counterblow pressure delivering means as well as puff or low pressure means for either puffing the parison during its invert movement from the parison mold to the up-right position at the blow mold or to help sustain the parison against collapse during invert.  The ability to apply puffing air to the parison during transfer is a significant step in the forming process.

Abstract: ABSTRACT              The damper system for controlling the flow of a gaseous fluid in a duct member is disclosed in which the combination of parallel and opposed flow characteristics is utilized to produce a composite rate of flow which varies substantially linearly with the angle of rotation of the damper blades over the full opening range. A plurality of damper blades pivotally mounted in substantially louvered fashion is utilized in one embodiment in which alternate pairs of blades are rotated in opposite directions to produce alternate parallel and Opposed passage flow characteristics.  In addition to being linear, the alternate parallel and opposed flow characteristics of the adjacent blade systems of the damper provide an additive advantage in mixing flow from different streams each being provided with one of the dampers.  This can be produced by combining the alternate swirling and sheet flow of the damper openings in a manner which produces intermeshing of the flow and com-plete mixing of the two streams.  In another embodiment, the combination of parallel and opposed damper flow is produced by the use of fixed blade insert members disposed between pairs of damper blades which are operated in conventional parallel fashion.
