Title: Character segmenting system of ocr
Inventor: MAEDA MAMORU
IPC: G06K9/00
Filed: 1983-06-07
Abstract: PURPOSE:To segment the character lines with high accuracy by deciding the presence or absence of the continuity of the projection component in the horizontal direction by the size of the projection component of a notice line under processing and by a result of decision whether the notice line exists in the character line or not. CONSTITUTION:The size of the projection component of the horizontal direction obtained by a projection counter 57 of a projection component and continuity detection part 5 is compared with the prescribed threshold value. When the size of the projection component is smaller than the threshold value, the state is checked for a continuity FF55, i.e., the result of decision of a continuity decision circuit 54 of the detecting part 5 to decide whether the present line exists in a character line or not. Thus the extraction is performed for a character line where a part of a character pattern is never cut out. Thus each character pattern is segmented from an image memory part 6 where the picture signals of the character line are stored. The segmented image patterns are sent successively to a pattern recognition part.

Title: Multicolor direct plate making method
Inventor: KANEDA EIJI
IPC: G03F3/00
Filed: 1984-05-18
Abstract: PURPOSE:To obtain a multicolor print faithful to an original high in quality by exposing each yellow, magenta, cyan, and black plate to the light transmitted through each color separated transparent dot image obtained by color separating an original multicolor image of continuous tone, and exposing said black plate to each reflected line image.

Title: Pulverized coal burner with improved resistance to wear
Inventor: MASAI TADAHISA
IPC: F23D1/00
Filed: 1982-06-15
Abstract: PURPOSE:To improve resistance to wear and to enable the reuse of a device through partial replacement of the device in case wear occurs, by detachably attaching a protecting plate, made of a wear resisting material, to an inner wall surface of an elbow. CONSTITUTION:The gas containing pulverized coal rising through a pulverized coal feed pipe 14 is given a whirling force at an inlet of an elbow 8 by vanes 13 for mixing the pulverized coal and flows in the elbow where the flow passage of the gas varies its direction by about 90 deg.. In the case of said variation in the flow passage, the pulverized coal tends to be dispersed to the outside of the flow or a protecting plate 3 side by inertia. By said dispersing action, the pulverized coal (c) frictionally passes the protecting plate 3 side, but since the protecting plate itself is made of a wear resisting material, the life of the device, mainly the elbow, is lengthened. Additionally, when the protecting plate itself is worn out or damaged, the protecting plate is made replaceable. This permits the improvement of resistance to wear and tear, and besides, even if wear occurs, merely the partial replacement of the device enables the reuse of the device.

Title: Flash camera device
Inventor: IWATA HIROSHI
IPC: G03B7/16
Filed: 1981-06-29
Abstract: PURPOSE:To simplify operation by automatically moving the light generation part of an automatic flash device corresponding to the brightness of a subject after a shutter release button is half-pressed, and relating the operation of the flash device to said movement at the same time. CONSTITUTION:When a shutter button 3 is half-pressed to turn on a switch 4, a power source supplying circuit 5 operates to connect a power source 6 to a brightness detecting circuit 7 and a motor control circuit 8. When the brightness of a subject is less than a desired value, a motor 14 rotates to elevate a light emission part 15 up to the position indicated by a dotted line 18. Then, a switch 19 is short-circuited to power down the motor 14, and the light generation part 15 stays at the elevation position. This results in that the distance between optical axes of a main lens and the light generation part is increased.  At the same time, a switch 20 provided at the same position with the switch 19  is also short-circuited, so the power source is connected to a light generation  device 21 to turn on the light generation part 15, thereby starting the operation of the flash device.

Title: Three-dimensional radar echo generator
Inventor: SAITOU YUKIO
IPC: G09B9/00
Filed: 1981-06-30
Abstract: PURPOSE:To use effectively a three-dimensional radar echo generator for training, by outputting an echo pulse when the difference between the half of the  beam width and the absolute value resulting from the subtraction between the  azimuth of an objective material and the current azimuth of an antenna is reduced to a value determined preliminarily by the angle of elevation. CONSTITUTION:An azimuth thetaT of the echo to be generated is subtracted from a current azimuth thetaA of an antenna in a subtracting circuit SUB1; and only when 1/2=thetaB of the antenna beam width is larger than or equal to the absolute value of this subtraction result, the output is issued from a comparing circuit CMP. Values alpha0, alpha1...alphan which are outputted in accordance with an angle phiT of elevation at the view of the echo from the radar and determine the pulse position are subtracted from the 1/2 beam width thetaB in a subtracting circuit SUB2. The output of the circuit SUB2 is subtracted from the output of the circuit CMP in a subtracting circuit SUB3; and when the output is zero, it is detected by a detecting circuit ZDT1, and information 1 indicating ''echo presence'' is written in a memory MEM through an OR operating circuit OR. If a switch SW is switched to the R side to read out information 1, one echo pulse is generated from a pulse generating circuit ECH.
