Title: Glass coating method and resulting article
Inventor: CALLIES GERALD A
IPC: C03C17/00
Filed: 1986-09-29
Granted: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE    A continuous, chemical vapor deposition method for producing a coated glass article is disclosed.  A glass substrate is advanced continuously, while hot, past first and second treating stations.  A non-oxidizing atmosphere is maintained in the vicinity of the first treating station, while an oxidizing atmosphere is maintained in the vicinity of the second station.  A non oxidizing gas which contains a silane, e.g., SiH4, is directed from the first treating station against a surface of the glass to form a silicon coating on that surface.  An oxidizing gas which includes a metal compound in the vapor phase is directed from the second station against the silicon-coated surface of the article.          The process is controlled so that the silane-containing gas forms a reflective silicon coating on the glass surface, the oxidizing gas which includes a metal compound forms a coating of an oxide of the metal, and oxidation before the article reaches the second treating station forms a silicon oxide layer on the silicon which is of sufficient thickness that the metal oxide layer is substantially free of pinholing.

Abstract: RACK ASSEMBLY FOR FORMING SPLINES IN THIN-WALL MEMBER                          ABSTRACT           An  apparatus   (10)   and  die  assembly (26,30)  for forming a splined power transmission member  from a  thin-walled  blank.   The apparatus (10) comprises a pair of die assemblies  (26,30), each including a supporting frame (28), first (42) and second (44) die bodies independently mounted on the  supporting  frame  (28)  in  end-to-end  coaxial relationship with each other, with rough (46) and finish (48) spline-forming surfaces formed on the first   (42)   and   second   (44)   die   bodies, respectively.   The pair of die assemblies (26,30) are supported with the spline-forming surfaces of the  respective  die  bodies  (42,44)  in  spaced, opposed, parallel relationship to each other.   A power drive mechanism sequentially moves the pair of  die  assemblies  (26,30)  in  opposed  directions from a neutral position in which the rough spline-forming surface (46) of the first die body (42) of one  of  the  pair  of  die  assemblies  (26)  is  in opposed relationship to the finish spline-forming surface  (48)  of the  second die body  (44)  of the other of  the pair of die  assemblies  (30).   The power  drive  means  effectuates  a  rough  spline-forming stroke in which the die assemblies (26,30) move from the neutral position first to a position in which the rough spline-forming surface  (46) of the first die body (42) of the one assembly (26) is in  opposed  parallel  relationship  to  the  rough spline-forming surface (46) of the first die body (42) of the other assembly (30) and then return the die  assemblies  (26,30)  to  the  neutral  position. Subsequently,  there  is  a  finish spline-forming stroke  in which  the  die  assemblies  (26,30)  are moved first from the neutral position to a position in which the finish spline-forming surface (48) of the second die body (44) of one of the assemblies (26)  is  in opposed  parallel  relationship to the finish spline-forming surface  (48)  of the second die body (44) of the other die assembly (30) and then returned to the neutral position.

Title: Optical character reader
Inventor: YAMAGUCHI MIKIO
IPC: G06V30/146
Filed: 1987-07-09
Granted: 1991-04-16
Abstract: OPTICAL CHARACTER READER    ABSTRACT OF THE DISCLOSURE     The invention provides an optical character reader (OCR) utilizing prioritized horizontal OR ranges for enhanced accuracy and ease of use.  A light source illuminates a price tag or the like on which characters have been imprinted generally along a horizontal direction of the sheet.  A lens system images the characters onto an image sensor having a field of vision covering a plurality of characters, the image sensor including a plurality of photo-electric conversion elements arranged in a matrix.  A binary coding circuit digitizes outputs of the photo-electric conversion elements, which define picture elements (pixels), of an image in the field of vision of the image sensor, into binary signals representing black and white picture elements.  A hand holdable scanner incorporates the light source, image sensor, lens system and binary coding circuit.  An identifying circuit identifies characters from binary-coded data.  The OCR utilizes at least two horizontal OR ranges in the field of vision of the image sensor.  When the horizontal OR range of higher priority detects a character line, the result of character line detection is output.  When none of the horizontal OR ranges detects a character line, it is determined that there is no character line. The character line detecting operation of each of the horizontal OR ranges is the same as that in the conventional OCR,  However, in the OCR according to the present invention, the horizontal OR ranges are spread horizontally.  Therefore, even in the case of a price tag which is long enough to have characters arranged along one of its sides, the character line or lines can be positively detected.  Since at least two horizontal OR ranges are provided in the field of vision of the image sensor, therefore the pattern of the background of the price tag and the characters on the price tag can be distinguished from each other.  This means that the OCR can be used for relatively small in size price tags.  The OCR conserves electric power when it is not actively "reading" data by suspending its character identifying operations when not needed.  Lines having no characters are identified and, in response, character identifying operations are stopped.

Abstract: Abstract There is disclosed a multi-processing arrangement in which processes running on one processor may utilize processes, called stub processes, running on other processors.  One problem that occurs with respect to such a system is that signals, which indicate the occurrence of external asynchronous events, must be processed in a specified order if the system is to work properly. Disclosed is a system for insuring the proper processing of such signals by requiring all such signals to be routed from a receiving process on an adjunct processor to the main user process on the originating processor.  Also disclosed is an arrangement for insuring that signals are not lost and that duplicate signals are not processed.

Abstract: ABSTRACT OF THE DISCLOSURE A method of press-molding defectiveness detection adapted for the detection of the press-bonding defectiveness of a terminal which is attached to the end of a covered wire so that a wire barrel and a insulation barrel of the terminal are press-bonded to a conductor portion at the end of the covered wire and a covered portion of the wire, respectively, by press-molding.  A profile of a press-bonding load acting on the terminal during terminal press-bonding operation is detected, and the press-bonding defectiveness of the terminal is determined by comparing the detected press-bonding load profile with a reference press-bonding load profile.  The press-bonding defectiveness of the terminal may be determined, as required, by comparing the integral value of the press-bonding load, calculated on the basis of the detected press-bonding load profile, with a predetermined reference value. Alternatively, the defectiveness may be determined by comparing a press-bonding load value at at least one point of time and the maximum press-bonding load value with predetermined reference values individually corresponding thereto.  Preferably, the press-bonding defectiveness of the terminal is determined by separately detecting profiles of press-bonding loads acting on the wire barrel and the insulation barrel, and comparing these profiles with reference press-bonding load profiles individually corresponding thereto.
