Abstract: Apparatus for automatically dispensing accurately a predetermined quantity of a liquid required to be stored at room temperature including a syringe pump, a liquid tank, and a pump displacement mechanism for moving the syringe pump between the liquid tank and a container. The piston of the syringe pump is displaced by a piston displacement mechanism. A weigher measures weights of the tank and liquid in the tank as well as a draining system for draining the liquid of the liquid tank. Liquid is supplied to the liquid tank from a supply system. A control device controls displacement of the syringe pump and the piston of the syringe pump, actuation of the supply system and the drainage system, and reads measurement output signals of the weigher.

Abstract: An optical character reading system in which a sheet upon which characters or symbols are printed is illuminated and the characters scanned with a two-dimensional photoelectric sensor. Output signals from the sensors are processed to read the characters through right and left frame detecting circuits. The right and left frame detecting circuits detect white/black patterns of frames formed on the sensor when the left and right sides of the characters extend beyond the ends of the ranges of the sensor. A circuit combines the white/black patterns detected by the right and left frame detecting circuits to provide a recognition of the characters being scanned.

Abstract: An optical character reading system in which each character pattern is electronically scanned several times while a manually held scanner is moved over the character pattern. The recognition results from each scan are subjected to a selection process and a final signal recognition result is generated in which noise and inaccurate recognition results have been substantially eliminated. Data from a character scanner is classified into several different data types from which partial characteristics are determined. Signals representing the partial characteristics operate a memory circuit which produces the final recognition signal.

Abstract: An optical character reading system first determines the height and width of the character to determine its authenticity and then examines the features of each line and/or column and classifies each line or column according to its pattern. The sequence in which the classification numbers occurs is indicative of the character detected. Correction of oblique scanning and direction determining features are also included.
