Title: Color developing method of electrophotography
Inventor: FUJII MASANORI
IPC: G03G9/08
Filed: 1984-07-30
Abstract: PURPOSE:To obtain color copies where the edge effect, brush marks, etc. do not occur with a high development sensitivity, by using a two-component developer consisting of a ferrite carrier whose volume resistivity is within a specific range and a positive toner including pigments for color in a binding medium for fixing. CONSTITUTION:A two-component electrophotographic developer 23 is used which consists of the ferrite carrier 1X10<7>-5X10<9>OMEGAcm volume resistivity and the positive toner (electric chargeable toner) including pigments for color in the binding medium for fixing consisting of a polystyrene resin, an acrylic resin, or the like, and the rotation direction of an arrow 15 of a photosensitive drum 1 and that of an arrow 17 of a sleeve 18 are opposite to each other, and a magnetic brush 25 and a photosensitive layer of the drum 1 are moved in the same direction in a developing area 26 to perform development. The volume resistivity of the carrier is specified to suppress the degradation of the development sensitivity and the occurrence of the edge effect when the brush 25 and the photosensitive layer are rubbed in the same direction by each other, and the occurrence of toner drawing, brush marks, etc. is reduced, and vivid color pictures superior in reproducibility of narrow lines are obtained.

Title: Semi-coaxial resonator control oscillator
Inventor: FURUYA NOBUO
IPC: H03B5/18
Filed: 1985-07-17
Abstract: PURPOSE:To attain simple and proper adjustment of an oscillating frequency by providing a microwave clap oscillator oscillated in itself and a semi-coaxial resonator adjusting the oscillating frequency. CONSTITUTION:When no resonance rod 25 exists, a microwave clap oscillator is oscillated in a frequency omegap. When the microwave clap oscillator and the resonance rod 25 are coupled properly, the oscillation frequency is, e.g. omegap1. When a fixed member 26 is used to adjust the resonance rod 25 to a high frequency than the frequency omegap1 to be omegap2, then the oscillating condition is not satisfied. Further, the fixed member 26 is used to adjust the resonance rod 25 to a frequency lower than the frequency omegap to be omegap3, the oscillating condition is not satisfied and the oscillating frequency is omegap. Since the oscillating skips between the frequencies omegap3 and omegap1 to be the frequency omegap, the range is inadequate as the setting range. According to the experiment, the frequency omegap1 is desired to be a frequency higher than the frequency omegap by 7-8%, and the band of the frequencies omegap1 and omegap2 is realized as 5-6%, and the oscillating frequency is varied by adjusting the fixed member 26.

Filed: 1991-06-28
Abstract: PURPOSE:To improve the reliability of character recognition by painting out close spaces, spaces opened to one side, and right upper and left lower spaces opened to two sides included in each character by the deformation processing and eliminating an influence of the noise or the like from the value of its oblique projection to precisely segment the character. CONSTITUTION:First deformation processing where a square area consists of four picture elements 1, 2, 3, and 4 and is successively scanned from the right to the left and from the top to the bottom to turn on the left lower picture element 1 in the case of turning-on of all other picture elements 2, 3, and 4 and second deformation processing where the square area is successively scanned from the left to the right and from the bottom to the top to turn on the right upper picture element 3 in the case of turning-on of all other picture elements 1, 2, and 4 are executed. The value of oblique projection related to the character is so sufficiently high that it is not affected by noise or the like when oblique projection of the deformation processing picture is taken, and as the result, a rather large value is so set that the noise or the like can be eliminated, and obtained isolated parts are allowed to precisely correspond to a character segmentation area.

Title: Measuring apparatus for distance between cars
Inventor: HOSOKAWA YASUHIKO
IPC: G01S13/93
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To obtain a measuring apparatus by which the distance between cars is estimated when the distance between cars becomes temporarily indefinite and which can prevent the lack of a measured result by installing an estimation means by which the distance between a preceding car and an own car is estimated on the basis of a plurality of measured distances. SOLUTION: A distance measuring part 1 measures a distance up to a preceding car by using a plurality of beams which make use of a laser or the like, it outputs a distance signal which indicates the distance between cars, and a road-curvature estimation part 2 estimates a road curvature on the basis of a car velocity and a yaw rate. A detection-beam selection part 3 selects a beam used to detect the preceding car out of the plurality of beams at the distance detection part 1 according to the estimated road curvature. A close-distance-signal estimation part 4 (an estimation means) estimates the distance between cars when the distance signal from the beam used to detect the preceding car becomes indefinite.  That is to say, when a plurality of distances measured continuously in a time-series manner are at a prescribed distance or lower just before the measured distance becomes indefinite, the distance between the preceding car and an own car is estimated on the basis of the plurality of measured distances.
