Title: Image forming device
Inventor: KASHIWAKURA KUNIAKI
IPC: G03G21/10
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a cleaning unit where residue toner can be eliminated well by preventing the turning up of a cleaning blade and the generation of abnormal oscillation. SOLUTION: In this device, since density of planting of bristles is made low near edges of a cleaning brush 74, toner eliminating ability of the cleaning brush 74 is deteriorated in these parts. Since the residue toner on a photoreceptor drum 1 is not eliminated in excess by the cleaning brush 74 in the both edge parts due to the deterioration of the toner eliminating ability, an appropriate quantity of the toner is fed to the cleaning blade 73. The generation of turning up or the abnormal oscillation can be prevented since toner functioning as a solid lubricator exists between the cleaning blade 73 and the photoreceptor drum.

Abstract: PURPOSE:To measure the hardness of a steel material without receiving the restriction for the size and shape of a test piece by photographing continuously a heated steel material by using a film and determining the cooling rate of the steel material from the change in the density of the film with respect to time. CONSTITUTION:Devices A, B, C and a test specimen D are used. A Jominy end quench test is performed. The test specimen D is continuously photographed upon starting of hardening. The density of the photographed film is measured by changing the distance from the hardening end with respect to the test specimen D of each frame and the density ratio is measured after development of the film. The density ratio is converted to a temp. The average cooling rate at certain distance from the hardening end is calculated. The distance from the hardening end is changed and the average cooling rate is measured in the same way as mentioned above. The relation between the average cooling rate of 800-750 deg.C and the hardness is determined from the continuous anisothermal transformation curve of the carbon steel contg. carbon approximately equal to the carbon content of the specimen D. The relation between the distance from the hardening end of the specimen D and the quench hardness is determined from the above-mentioned relation.
