Title: Auto convergence circuit
Inventor: ICHIGAYA HIROSHI
IPC: H04N17/04
Filed: 1988-10-21
Granted: 1992-10-20
Abstract: ABSTRACT OF THE DISCLOSURE    An electronic circuit automatically corrects the convergence of an electron beam of a color cathode ray tube.   Light reflected upon scanning by the electron beam of an index pattern disposed at a predetermined position on the shadow mask of the color cathode ray tube is detected by a photodetector.  A detected signal representative of the scanning position of the electron beam is obtained, and convergence error information is obtained based on the detected signal.  The correcting circuit  comprises an  integrator  for  integrating  the detected  signal  produced  during  a  plurality  of traverses of the index pattern by the electron beam. The convergence error information is based on the re-sult of the integration.  The effect of noise included in the detected signal is thereby reduced, and conver-gence correction with increased accuracy is obtained.

Granted: 1992-03-03
Abstract: SUBMERSIBLE ELECTRICAL CONNECTOR            ABSTRACT A submersible connector of the plug and receptacle type intended  for  use in environments characterized  in  having high  or variable pressures includes a fluid-filled  bladder into  which  open  a  plurality of  ports  for  receiving  a plurality of electrical probes.  The internal environment of the  bladder  protects electrical contacts  with  which  the probes  mate to form electrical circuits.  The integrity  of the bladder environment is maintained by use of an end  seal providing a radial constricting force on each of the  ports, which acts to form a pressure-tight seal on a probe inserted into  the  port to complete an electrical  connection.   The integrity of the internal bladder environment is  maintained when  the  probe  is withdrawn by means of  a  plurality  of socket assemblies, internal to the bladder, each  associated with  a respective one of the ports and including a  movable stopper   which  initially  protrude   through  the   socket assembly  into  the port.  The  constrictive  force  exerted through the port maintains a seal that protects the internal environment  of  the  bladder.  When  a  probe  is  inserted through  the port, the probe engages the stopper and  pushes it  out  of the port and back into the socket  assembly.   A return  mechanism  maintains a return force on  the  stopper acting against the probe, so that the stopper is moved  into the port simultaneously with the probe being withdrawn  from it.

Title: Apparatus and method for floating point normalization prediction
Inventor: ZURAWSKI JOHN H
IPC: G06F7/485
Filed: 1989-03-31
Granted: 1992-12-22
Abstract: ABSTRACT      The invention is directed to an apparatus and method for predicting the number of bits which must be taken into account to normalize the result of a floating point addition or subtraction.  The apparatus and method employ:  a low precision floating point adder/subtractor, a priority encoder that determines the position of the most significant non-zero bit to generate the normalization amount and preround logic which pre-shifts a rounding bit in the opposite direction of normalization.  The method and apparatus operate in parallel with a full precision floating point adder to eliminate the need for a full-precision floating point normalization calculation and rounding computation in most circumstances.  The normalization amount for successful low-precision floating-point addition/subtraction is calculated by the time the full-precision floating-point addition/subtraction stage occurs.  Moreover, the pre-round logic supplies a carry bit to the full-precision adder/subtractor thus saving the time associated with a full-precision rounding bit addition.  Thus, this low-precision floating-point addition/subtraction technique results in a significant enhancement of performance in floating-point addition/subtraction.

Abstract: One dimensional reproduction of stereophonic sound is described in which at least two microphones sense the sounds produced by at least one sound-generating point source.  The sounds sensed by the microphones are reproduced through at least two transducers spaced a distance apart.  The reproduced sounds comprise sets of incident travelling sound waves. Each set of incident travelling sound waves originates from a different transducer.  The sets of incident travelling sound waves are transformed into corresponding sets of waves which travel toward one another along a sympathetically vibratable sound-receiving surface which is located between the transducers and the listener.  The different sets of waves travelling along the sympathetically vibratable sound-receiving surface interfere with one another to produce separate and distinct standing waves in a direction perpendicular to the sympathetically vibratable sound-receiving surface. Each standing wave represents an individual sound-generating point source being produced at locations along the sympathetically vibratable sound-receiving surface relative to the transducers, corresponding to the location of each sound-generating point source relative to the microphones.

Abstract: The apparatus accepts dry stripped crude fiber such as straw or sugar cane wastes, coconut husks, or elephant grass, compacts them into a relatively dense sheet, and bonds a strong surfacing material such as a heavy paper to the faces and edges. The sheet, continuously flowing from the apparatus, is cut into standard lengths and the cut ends are capped with the same surfacing material. A precompactor near the end of an entrance chute into the apparatus uniformly predensifies the incoming fiber prior to its compaction by means of a ram. The ram is carried on roller bearings especially adapted to withstand the weight and other forces associated with the continuous movement of the ram. The compacted material is continuously propelled by the ram and enters a press, where heat and pressure produce a dimensionally stable sheet bonded together partially by natural resins released from the fibers by the heat, and partially by mechanical interlinking between fibers. In the following operation, the sheet is covered with the surfacing material, which is successively folded over and bonded to the edges of the sheet. The surfacing material, provided in discrete rolls, is continuously available from a feeder station, which facilitates the substitution of a fresh roll as the material is consumed. In the following sawing and end sealing operations, fully surfaced sheets of standard lengths are produced.

Abstract: In planetary gears for example the sun wheel may adjust itself freely within certain limits with respect to the planet wheels so that it seeks such a place for itself in which the load is divided evenly among the planet wheels. However a result of this arrangement is the tendency of the gearing to vibrate especially when the load on the gearing is small. The invention presents a planetary gear construction in which the shaft (7; 12) leading to the gearing or both the shafts leading to and away from (20; 21) the gearing are fastened to the gearing's frame (17) with bearings with the aid of an elastic part (10; 15; 22, 23). The said elastic part is a circular rubber bushing or such that is placed in connection with that bearing (19; 14; 24, 25) that is closest to the planetary gear and which represses the said tendency to vibrate but which at the same time allows the centralizing of the sun wheel or such. The invention can be applied to both planetary gears that are equipped with a ring wheel (3; 18) or to so-called incomplete planetary gears that do not have a ring wheel.

Abstract: Disclosed is a tubular casing of fiber-reinforced regenerated cellulose comprising a film web which is curved to form a tube. The edge regions of the film web, which run parallel to the longitudinal axis, abut or overlap slightly and are sealed by means of a film strip which covers both the edge regions. The film web and the film strip composed of the same material have, in the wet remoistened stage, a breaking strength of about 15 to 30 N/mm2 and an elongation at break of about 30 to 50% in the longitudinal direction of the web, and a breaking strength of about 15 to 35 N/mm2 and an elongation at break of about 30 to 50% in the transverse direction of the web. The breaking strength in the transverse direction of the web is equal to or greater than that in the longitudinal direction of the web. On its entire surface facing the film strip, the tubular casing has a substantially gas-impermeable and sealable layer, as has the film strip on the surface which comes into contact with the tubular casing. The film web is produced from viscose, and is prevented from shrinking during the process and is stretched in the transverse direction during drying. The tubular casing finds particular application as a sausage casing.
