Title: Character separating system
Inventor: MATSUURA TOSHIO
IPC: G06K9/36
Filed: 1984-03-23
Abstract: PURPOSE:To attain separation/extraction of characters which are written with no writing conditions by tracking the outer circumference of a character within a picture of an input character string with fixed conditions and segmenting an area of a character including the character to eliminate noises other than the character. CONSTITUTION:A character string area within a picture is fetched to a buffer memory 2 of a rectangular area after a digital picture such as a logical circuit diagram, etc. is stored to a picture memory 1. Then the character string area is scanned vertically to detect a tracking start point for outer circumference of character. Thus the outer circumference of the character is tracked by a round based on said start point and in a fixed checking order. A character frame area is segmented according to the minimum and maximum points which are extracted from said tracking process and stored to a one-character buffer memory 5 and then to a one-character store part 7 after elimination of noises through a noise eliminating part 6. The stored frame area is used for recognition of characters and also supplied to a one-character erasing part 8, and an EOR operation is performed between the separated character and a corresponding character of the memory 2. Then a character string including no processed character is stored to the memory 2.

Title: Reproducing device of magnetic recorded picture
Inventor: AKASHI SUMIMASA
IPC: H04N5/7826
Filed: 1982-04-01
Abstract: PURPOSE:To improve the S/N of reproduced pictures, by providing erasing heads in positions just before plural recorded picture reproducing heads of the helical should be written over, on the track where information is recorded just before. CONSTITUTION:Erasing heads H'a and H'b are provided in positions preceding plural recorded picture reproducing heads Ha and Hb (only the head Ha is shown in figure), which are attached to a rotary drum of the helical scanning system, at angles which are small as much as possible. A length W4 of the gap of erasing heads is made shorter than a length W1 of the gap of recorded picture reproducing heads, and erasing heads are attached in positions slightly higher than those of lower ends of reproducing heads Ha and Hb. The erasing head H'a erases information in the part of the end of a track T'b, where information is recorded just before by the reproducing head Hb, namely, the part of a width W3 where information should be written over by the head Ha. Thus, information is not recorded in this part of the width W3 by the head Hb, and the S/N of the output signal for reproduction is improved.

Title: Detecting device for speed of ink particles in ink jet printer
Inventor: MATSUOKA TAKAO
IPC: G01P3/68
Filed: 1979-05-07
Abstract: PURPOSE: To easily detect the flight speed of ink particles by detecting the intervals of ink particles which have a predetermined generation period.  
     CONSTITUTION: An ink flow injected from a nozzle 4 is applied with a ultrasonic vibration, and rendered into ink particles in synchronism with the vibration frequency thereof. For this reason, the interval of the ink particles 6 becomes constant if the speed of ink particles is constant. In a slit plate 5 arranged in parallel to the flying direction of the ink particles 6, a plurality of slits 51 are provided at an interval equal to that when printing can be made in a stable state or at an interval integer multiple of the above described interval. By this organization, when the interval of the ink particles 6 is a distance of a stable state, the quantities of light from a light-emitting element 3 reaching the light receiving elements 1 and 2 are equal. Unless so, a difference is produced between the quantities of light, and therefore it can be easily detected that the flight speed of ink particles 6 varies from the speed at the stable state.

Abstract: PROBLEM TO BE SOLVED: To provide a flexible strain sensor which can constitute a fail-safe safety system in a simple structure. SOLUTION: A flexible strain sensor 1 is composed of a thin film-like conductor 2, a resin material 3, and lead wires 4a and 4b. The resin material 3 covers the conductor 2 in a pinching state and the lead wires 4a and 4b which are connected to the conductor 2 are exposed from both end sections of the material 3. The strain of the sensor 1 in the direction of elongation can be detected from the variation of the electric resistance value between the lead wires 4a and 4b. At the time of using the sensor 1, prescribed tension is applied to the sensor 1 in a non-displaced state and the strain of the sensor 1 is detected from the variation of the electric resistance value from this state.  Since the tension is preapplied to the sensor 1 in the above-mentioned way, the fault or abnormality of the sensor 1 itself resulting from disconnection, coming off, etc., can be detected from the variation of the electric resistance value.
