Title: Method and device for adjusting toner density
Inventor: FUSHIDA AKIRA
IPC: G03G15/08
Filed: 1982-10-22
Abstract: PURPOSE:To adjust toner density automatically and accurately by rubbing a mesh screen against a magnetic brush and impressing a bias voltage between the screen and a magnetic brush support body. CONSTITUTION:The mesh screen 8 allows a magnetic carrier 12 forming the magnetic brush 3 and a toner particle 11 to contact each other and have mutual friction through an opening 9, and also performs scraper-like operation for scraping the toner particle 11 in the magnetic brush 3 by its shield part 10. Consequently, when the toner density in the magnetic brush 3 is low, the toner particle 11 is attracted electrostatically into the magnetic brush 3 through the mesh opening 9 and when high, the excessive toner particle is scraped out of the magnectic brush 3 to stay on the screen 8. When the toner for a positive electromagnetic latent image is employed, the impression of a negative bias voltage to the screen 8 generates resiliency for forcing the toner particle 11 to the carrier side 12 with reverse polarity to increase toner suction and impression of a positive bias, on the other hand, suppresses the toner suction.

IPC: H04N1/04
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To highly accurately judge the achromatic color image of original images without depending on a read variable power rate. SOLUTION: In the case of reading the original image by the respective line sensors of RGB provided with a prescribed interval in a sub scanning direction, a read speed in the sub scanning direction is controlled corresponding to a set variable power rate. At this time, since a space of an offset line number corresponding to the variable power rate is present between the respective line sensors, it is required to delay image data from the line sensor of a certain color component by the offset line number to the image data of the other line sensor. The offset line number does not always become an integer. A judgement area in (a) is used in the case that the decimal part of the offset line number is close to 0 and an achromatic color judgement area is enlarged as in (b) when the decimal part is closer to 0.5.

Title: Reinforcing method of optical fiber arc welding connection part
Inventor: KAKII TOSHIAKI
IPC: G02B6/24
Filed: 1982-10-22
Abstract: PURPOSE:To reduce transmission loss and to improve reliability for a long period by reinforcing an arc welding connection part while tensile force is loaded on both ends of an arc welding connected optical fiber core. CONSTITUTION:A core 1 is drawn previously by 200g tensile force 4 and while a bare fiber 2 is tensed without curvature, the arc welding connection part 5 is reinforced by a reinforcing method in which a heat shrinkable tube is used as a reinforcing member 3. Consequently, this method wherein the tensile force is loaded prevents the curvature of the bare fiber part 2 and suppress an increase in transmission loss due to the reinforcement to <=0.01dB while a method wherein the tensile force 4 is not loaded causes an about 0.06dB increase in transmission loss estimated to be caused by the curvature of the bare fiber 2. Further, the rate of the disconnection of the arc welding connection part 5 due to about 200g tensile force 4 is <=1% and the tension is loaded to eliminate trouble such as breaking.
