Title: Nonwoven fabrics for printing
Inventor: UMEZU NORIO
IPC: D04H1/64
Filed: 1991-02-08
Granted: 1999-04-06
Abstract: A nonwoven fabric, particularly composed of long-stock synthetic resin yarns such as polyethylene and polypropylene is provided at one or both surfaces thereof with an inksetting layer formed by coating, drying and curing a resin composition containing some of acrylic resins, synthetic rubbers and polyester resins.  The ink-setting layer is excellent in the transfer property and fixing ability to an oil ink which is ordinarily used for offset printing, and prevents the nonwoven fabric from being swelled or transformed by a petroleum high-boiling-point solvent contained in the oil ink.  Preferably, a low-temperature cross-linking agent is incorporated with the resin composition of the ink-setting layer so as to complete cross-linking of the resin composition at a low temperature at which heat shrinkage or heat damage of the nonwoven fabric will not be caused, in a shortened period of time.  Moreover, when 10 to 40% by weight of non-calcined clay, 1 to 15% by weight of titanium dioxide and 1 to 10% by weight of calcium carbonate or calcined clay are incorporated as fillers in the resin composition of the ink-setting layer, the ink-setting layer has improved absorbability, drying ability and fixing ability to a printing ink.  A preferable construction of the nonwoven fabric has a first layer containing the low-temperature cross-linking agent and a second layer containing the specific filler ingredients.

Title: Character recognizing system
Inventor: KAMEYAMA HIROFUMI
IPC: G06V30/146
Filed: 1991-02-27
Granted: 1996-01-09
Abstract: According to this invention, a plurality of recognition candidates are obtained through continuing a segmentation to a numeral recognition realized by segments, an optimum one is selected from among the candidates by means of connection information, thereby preventing the continuous numerals from being recognized erroneously.  This invention is a method of correctly recognizing the handwritten characters, especially the numerals written in such as a checks, said method which comprises the steps of: performing a line drawing analys is of the character set to be recognized in order to extract a characteristics of the arrangement of blocks, proposing a hypothesis about the monetary unit type, and finally verifying the above hypothesis to display the result of the character recognition.  Further, this invention method can surely distinguish handwritten characters from a bar which is either printed for entry of characters or  handwritten, and eliminate the bar from the object of character recognition to extract the characters alone.  In detecting the bar, six formulas for under-bar, middle-bar, upper-bar, inclined bar, inclined under-bar and inclined upper-bar as relative to the characters are used to determine certainty factor of a bar, and the bar having the highest linearlity is extracted.

Filed: 1993-01-28
Granted: 1996-03-19
Abstract: A shifting mechanism for a multi-speed manual overdrive (OD) transmission.   A "flipper" reverses the action of the shift stick for the final stage shift fork to maintain progressive "H" or "HH" shift patterns yet engage a direct drive coupling as the next-to-last range and OD as the final engagement.  The mechanism employs a quadrangular frame slidably received on two adjacent shift rails in a shift rail array.  The frame has one side above the shift rail array notched to engage the shift stick end of an opposite side below the array.  the flipper is pivotally mounted below the array with one end engaging a notch in the frame and the other end engaging the final stage shift fork so as to minimize bending stresses on the fork end and reaction loads of the sliding frame on the shift rails.

Title: Packaging machine with thermal imprinter and method
Inventor: WEHRMANN RICK S
IPC: B41J15/06
Filed: 1993-03-24
Granted: 2000-08-01
Abstract: A thermal transfer printing apparatus for printing an elongate continuous web of items. The apparatus comprises a frame structure having an imprinter mounted thereon. A plurality of idlers supports the web of items and defines a path of travel for the web. A segment of the path of travel is adjacent the imprinter and its print head. A rockable arm is connected to the frame structure and contacts the web along a top surface of the web at two locations. A first of the locations is upstream of the print head and a second of the locations is downstream of the print head. The arm is connected to the frame structure about a pivot point and rocks about this pivot point during operation of the apparatus in a manner similar to a "teeter-totter." A stepper motor drives two drive rollers thereby advancing the web. When a selected item is in a proper printing position within the segment of the path of travel adjacent the imprinter, air cylinders actuate a nip and the print head against the drive rollers to maintain proper tension within the selected item. The rockable arm then rocks about its pivot point and the stepper motor drives the drive rollers to pull the selected item past the print head so that the item may be imprinted.

Abstract: An injection apparatus that is particularly suitable for accurate and precise injection of eggs of varying sizes and that may be presented to the injection apparatus in somewhat different orientations. The injection apparatus comprises a generally horizontally oriented tooling plate with an opening therethrough, an injector resting generally vertically in the opening in the tooling plate with a lower portion of the injector depending downwardly below the tooling plate and an upper portion of the injector resting at or above the tooling plate. Means are included for raising and lowering the tooling plate and the injector therewith so that when the plate is lowered and the lower portion of the resting injector strikes an egg to be injected, the resting injector stops while the tooling plate proceeds downwardly until the injector disengages from the tooling plate and is free to move in a translational direction independent of said tooling plate. When the tooling plate is raised it reengages the injector and carries it upwardly and away from the egg.
