Title: Electron beam welding device
Inventor: KANEUCHI HOHACHI
IPC: H01J37/304
Filed: 1980-08-11
Abstract: PURPOSE: To make the reduction in the size of the vacuum chamber and exhaust device of an electron beam welding device possible by maintaing the deflection speed of an electron beam constant in welding objects to be welded by deflecting the electron beam on their weld line.  
     CONSTITUTION: An electron beam 2 generated from an electron beam generator 1 is deflected with a deflection coil 3 and while it is being moved in the direction of 8 along the weld line 7 of objects 6 to be welded, said objects are welded. In this case, at the same instant when the deflection of the electron beam is started, the set signal of a deflection speed setter 20 is applied to an integrator 24, and the  output 27 thereof is applied to an inverse function generator 25, by which it is  converted to an outpt 28 (tan -1 KT) and is applied to a power amplifier 26 of 1  amplification factor. This outpt IDEP is applied as deflection electric current to the  deflection coil. Since the deflection speed is made constant and the movement of the  objects to be welded is made smaller in spite of increasing the deflection angle of  the electron beam, the vacuum chamber and the exhaust device ancillary to this are  made smaller in size.

Title: Word processor
Inventor: YOSHIKAWA MASATAKA
IPC: G06F17/21
Filed: 1986-05-14
Abstract: PURPOSE:To omit the labor of reinput of a character and easily change the character size by providing a character classification changing means if the size of the inputted character is changed after. CONSTITUTION:Character code data inputted by an input means is stored in a storage means 19. When a user wants to change the size of one character of this inputted sentence, one character in the storage means 19 is selected as the change object by a selecting means on a keyboard 3. When a classification change key on the keyboard 3 is operated, a CPU 11 responds to an execution command signal to read out character code data of the change object character stored in a work memory 14 and reads this data into a register of the work memory 14. The CPU 11 discriminates whether the character classification of the character code read into the register coincides with the current set character classification mode or not, and character code data selected as the change object is rewritten with the new designated character classification if they do not coincide with each other.

Title: Character recognizing device
Inventor: HIGUCHI KOICHI
IPC: G06K9/62
Filed: 1989-04-28
Abstract: PURPOSE:To reduce an undesirable influence caused by a position fluctuation of a character line by varying and setting a boundary of divided areas by following a position fluctuation of the character line. CONSTITUTION:A pattern projecting part 20 projects an original pattern in a circumscribed frame onto an arbitrary projected straight line on a plane containing this original pattern and finds a distribution of the number of black bits of the original pattern in the circumscribed frame. Also, a divided point determining part 22 determines a divided position on the projected straight line of a divided point so that the sum of the number of black bits in a section between adjacent divided points with regard to the original pattern in the circumscribed frame becomes roughly equal in each section. Subsequently, a feature extracting part 13 forms a boundary line of partial areas by a straight line for passing through each divided point and intersecting with the projected straight line and sets each boundary line so as to become parallel to each other. Accordingly, even if a position of a character line is fluctuated, a position of the partial area follows a movement of the position of the character line. In such a way, a fluctuation of a feature extracted with regard to the same character can be reduced.
