Title: Cleaning device
Inventor: ADACHI HIROYUKI
IPC: G03G21/10
Filed: 1982-08-20
Abstract: PURPOSE:To prevent a removed developer from entering around a blade end part into the cleaned image formation area of an image carrier, by the constitution which has a cleaning member abutting on the image carrier crossing its movement direction and a catching member abutting on the surface of the image carrier of a downstream side at the end of the cleaning member in the movement direction. CONSTITUTION:A developer removed by an elastic cleaning blade 11 is separated from the image carrier 1 by a removed toner guide sheet member 12 and guided into a housing 3. The catching member 14 abuts on he surface of the image carrier 14 on the movement-directional downstream side of the cleaning member end part to catch a removed developer overflowing over the end part of the blade 11. The catching member 14 is applied with enough pressure to clean off the overflowing developer. An alternate long and short dash line P indicates the boundary of the picture formation area on the image carrier 1, and the right-hand side shown by an arrow is the formation area. The catching member 14 has its end part positioned at up to the boundary P and never enters into the picture formation area. Consequently, the generation of partial wear by sliding friction with the catching member 14 in the picture formation area of the image carrier 1 is prevented.

Abstract: PURPOSE:To detect a corresponding area with a good accuracy by standardizing respective density values in the areas of plural pictures to be operated so as to correct the influence such as the unevenness in a density or a brightness and arithmetically operating correlation. CONSTITUTION:A specific setting area X is extracted from the one variable density picture A from plural variable density pictures A, B stored in picture memories 1a, 1b and the corresponding setting area Y is extracted from the other variable density picture B. Then, the standard deviation of the density value is calculated to the respective picture signals of the areas X, Y by standard deviation calculators 2a, 2b. Then, the density value is extracted for every picture element and it is divided by the standard deviation by dividers 3a, 3b to standardize.

Title: Coupling nail
Inventor: NAKADA TAKAHARU
IPC: F16B15/08
Filed: 1977-12-06
Abstract: PURPOSE: To ensure working effects, such as, the large holding force of sharpness, easy guide in a magazine portion material, no directional properties after nailing, sure separation at the centers of pitches, etc., and to use this nail for a rivetting machine.  
     CONSTITUTION: This coupling nail 1 is arranged by connecting a number of signle nails 2. Each signle nail 2 is each shaped from a head portion 3, a shank portion 4, a nail drum portion 5 and a nose portion 6. Since the head portion 3 is circular and has no directional properties, the consideration of the nailing direction of the single nail 2 is unnecessary. Connecting wings 8, 9 are each disposed to the shank portion 4 and the nail drum portion 5. The sectional areas of outer edge portions 11, 10 are each set to the minimum in the connecting wing ornaments 8, 9, and each single nail 2 is mutually connected at said outer edge portions 11, 10. Consequently, each outer edge portion 11, 10 corresponds to the centers of the pitches of the coupling nails 1, thus resulting in the separation of each single nail 2 at the centers of the pitches.
