Title: Processing system for picture of segmented character from document
Inventor: HONMA KOICHI
IPC: G06K9/34
Filed: 1986-08-01
Abstract: PURPOSE:To speedily extract a minimum rectangle circumscribing a character by detecting a section in one line, where black picture elements are continued, obtaining the OR between the current and next lines at every section and attaining the upper and lower ends of the frame of a segmented character. CONSTITUTION:Figure (a) shows two characters are composed of three linked black picture element patterns. Since the rectangles circumscribing the two linked picture elements overlaps with each other, the characters are segmented by one circumscribing rectangle. Figure (b) shows that the section of continuous black picture elements increases because two lines are ORed. However the section of continuous black picture elements disappears at a point where no black picture element lies on the next line. Figure (c) decides whether the position where the section of continuous black picture elements disappers exists or not, that is, whether black picture elements lie in a next line section from the lower end point in the circumscribing rectangle toward an upper direction. If not, a line number is outputted as the upper end point in the circumscribing rectangle. If a lower end in another circumscribing rectangle appears in the section, both sections are unified to attain one section. Thus the numbers of the top and bottom lines in the rectangle where each character is segmented can be detected, and the positions of right and left widths can be detected from the end point of a black element decision section when the upper end is detected.

Abstract: PROBLEM TO BE SOLVED: To suppress vibrations to a rear side at the time of sound generation and to improve discharge sound quality by allowing a duct, which has an opening on the rear of a loudspeaker unit having a diaphragm that generates sound with vibrations and which is tubularly formed, to satisfy a specific relationship among air mass in the duct, acceleration for the air to move, diaphragm mass and the acceleration. SOLUTION: A duct 4 is tubularly arranged on a loudspeaker unit 1 with its center on the same line as the center of diaphragm 18. Here, the duct 4 is formed so that the relationship: mDαD=AM0 d0 is satisfied where mass of the diaphragm 18 is m0 , the acceleration at the time of vibration is α0 , air mass in the duct 4 is mD and air acceleration at the time of vibrations is αD. In such cases, the duct 4 can absorb discharge vibration waves of a vibration system 10 by making the force of vibration waves from a speaker unit 3 equal to the air discharge force of the duct 4 to the outside, where A is assumed to be one. However, the vibration waves from the unit 3 is suppressed with A in a range of 0.5 to 1.5, considering the errors of the unit 3 and the duct 4.
