Title: Character extracting device
Inventor: IRIE YOSHIHIRO
IPC: G06K9/20
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To extract only character information from a slip, etc., having a multicolored frame fast by previously setting a color recognition area and generating a background-ruled line color reference line from an RGB read output, and determining character information or ruled-line information according to the distance from the reference line. SOLUTION: This device is equipped with an image input part 1, a character extraction part 2 which includes a color information storage part 2S, a distance arithmetic part 2C that reads out a character area including a ruled line and calculates its distribution and the distance to a ruled-line color reference line, and a comparing means that compares a distance calculated by the distance arithmetic part 2C with a predetermined threshold value and takes out character information when the distance is larger, etc. In this constitution, the background- ruled line color reference line is previously generated and the value of the distance from the center of the distribution of the background color and ruled- line color in an RGB space is found from the original image including the ruled line. Only when the distance value is larger than the threshold value, the information is taken out and binarized into character information to be taken out.

Abstract: PURPOSE:To eliminate the deterioration of a diffraction grating due to meltback at the time of crystal growth and to contrive to obtain the diffraction grating of good quality by a method wherein a semiconductor laser is provided with a clad layer of a flat structure, wherein mixed crystal parts and superlattice structure parts are regularly repeated, and this clad layer is utilized as the diffraction grating. CONSTITUTION:GaAs-AlAs superlattice structure parts 2A and AlGaAs mixed crystal parts 2B, made by Si ion implantation in a GaAs-AlAs superlattice structure at a pitch of about 3000Angstrom  and by an annealing, are provided on an N-type GaAs substrate 1. By turning the GaAs-AlAs superlattice structure into a mixed crystal at a pitch of about 3000Angstrom , the periodic change of the refractive index can be obtained. For example, if the superlattice structure is turned into a mixed crystal and becomes an Al0.53Ga0.47As superlattice structure, the refractive index becomes smaller by 0.2. A clad layer having the periodic change of a refractive index at a pitch of 3000Angstrom  or thereabouts can be used as a tertiary diffraction grating to light to ooze out to a guide layer 3 from an active layer 4.

IPC: G06F9/46
Filed: 1994-10-18
Abstract: PURPOSE: To promptly activate an entire picture processor even when the number of job tasks is large by deciding a range capable of processing jobs based on the result of detection whether or not the job task is in a state capable of processing the job. CONSTITUTION: The respective job tasks transmit a message 'taskavailable' to a job task management task 15g at the point of time when the processing of a printing job becomes possible in the respective job tasks. After activating the respective job tasks, the job task management task 15g updates a task management table by the message transmitted by the respective job tasks corresponding to the state and decides the range capable of performing processings corresponding to the set state of the table. Thus, for instance, a LAN reception task 15b and a parallel reception task 15c can receive the printing job from a work station N being a host without waiting for the activation of a printing part management task 15f and a job analysis/expansion task 15e and activation time as the entire processor is shortened.

Abstract: PURPOSE:To improve machining precision at a corner part, by providing a control device which predicts a change in a machining amount at a corner part and corrects a change in a gap between the sides of electrodes occasioned by a change in a machining amount. CONSTITUTION:A control device 14 selects the gain of a new interpole servo for machining a preset corner part by means of a signal from a discriminator 12, indicating that a present position is under circular movement of a corner part, and a signal from a discriminator 13, indicating that present machining is finish machining. The control device switches the gain of the interpole servo, and restores the gain of the interpole servo to its original value upon completion of machining of the corner. Since, for example, in the case of machining of the in-corner, with the increase in a machining amount, a gap between the sides of electrodes is increased to cause overcut, to control device 14 prevents the occurrence of phenomenon, in that a machining speed is excessively decreased at the in-corner, by switching the gain of the interpole servo to a low value, resulting in correction of overcut by a machining integration effect.
