Title: Character recognizing device
Inventor: YOSHINAGA TAKESHI
IPC: G06K9/32
Filed: 1987-10-14
Abstract: PURPOSE:To improve a recognition rate when a character string has a gradient by recognizing a character as a black picture element lump, calculating the quantity of the gradient to the character recognition reference of a straight line connected thereto, correcting the quantity of the gradient, thereafter recognizing the quantity. CONSTITUTION:A picture signal from a picture input device 1 is binarized in a processor 2 and stored in a memory 3. The black picture element lump corresponding to the respective characters is separated by a black picture element lump separating means 21 to calculate the center of gravity of the respective black picture element lumps. Then, the straight line approximating the aggregation of the center of gravity is obtained by the Hough transformation to calculate the quantity of the gradient of the straight line by a gradient calculating means 24 and correct the picture signal stored in the memory according to the quantity of the gradient. Thereby, a character recognizing part 4 segments the character from the picture signal where the quantity of the gradient is corrected to recognize the character. Accordingly, the gradient of the character string is automatically corrected to improve the recognition rate.

Title: Punching device
Inventor: MORI YASUTOKU
IPC: B26D7/18
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent punched scraps from being left in a punching edge and on a product side by forming a vent passage to communicate a suction port formed on a forward end face with the atmosphere side in an elastic and expandable member.

Title: Three-way valve
Inventor: TOMOSUGI HIROYUKI
IPC: F16K11/14
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To control a pressure at a low cost with high precision through a single valve drive part by a method wherein a valve drive member is formed in size lower than a minimum distance between first and second valves and drive by a valve drive means being different from the first and second valves. SOLUTION: The thickness D of a switching plate is decreased to a value lower than a minimum distance between two valve bodies when first and second valve bodies 8 and 9 are both brought into a closed state. Since in an initial state wherein energization to a linear solenoid 12 is stopped, the energization force of a return spring 13 is increased to a value higher than that of a spring 11, a second valve body 9 is brought into an opening state wherein it is separated away from the valve sealant 7L of a valve seat part 2a. The first valve body 8 is energized in the direction of the valve seat part 2a through the force of a spring 10 to maintain a closed state.  Thus, only a portion between a negative pressure port 5 and an output port 6 is brought into a communication state, and an atmospheric pressure outputted through the output port 6 is bled through the negative pressure port 5 and a pressure is reduced to generate and feed a negative pressure.
