Title: Method for measuring surface scale of steel plate and method for measuring material quality
Inventor: TORAO AKIRA
IPC: G01N21/47
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To continuously measure on line not only a scale thickness, but a crystal particle size and a hardness of a stainless steel plate after annealing. SOLUTION: An infrared emission light from a surface of a steel plate 2 is detected in an anneal furnace 3. A quality of the steel plate is measured based on the emission light according to this steel quality-measuring method. A luminance temperature at a wavelength whereby an emissivity is approximately constant even when a scale thickness changes, and a luminance temperature at a wavelength whereby the emissivity changes to a change of the scale thickness are measured by a measuring device 1. A soaking temperature of the steel plate is calculated based on preliminarily obtained emissivity and luminance temperature at the former wavelength. The emissivity at the wavelength is calculated based on the soaking temperature and the latter luminance temperature, based on which the scale thickness is obtained.  A soaking period from a predetermined temperature of the steel plate to the soaking temperature is calculated based on the scale thickness and soaking temperature. A quality of the steel plate is measured based on the soaking period and the soaking temperature.

IPC: G03G15/01
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To minimize a total charge imparted to a toner layer and to reduce a mutual pollorion by making a lamp irradiate a photoreceptor and removing the charge of the photoreceptor before the next AC re-electrification of the photoreceptor, which is performed to expose a next color image, after developing the 1st toner layer. SOLUTION: Re-electrification is performed well when a photoreceptor is exposed first so that the charge of an image area is made to lower before the re-electrification. Then, a pre-electrification erasing lamp 18 is used to expose the image area. When the image area advances passing through the lamp 18, the lamp 18 irradiates the image area. The developed image area is discharged by the lamp 18 and the potential of the photoreceiving body is lowered to the potential obtained by adding all voltages to a residual voltage being about -25 V by a charge on a developed toner. After passing through the lamp 18, an AC scorotron 22 re-electrifies the image area to a charge level which is desirable to expose and develop a yellow image.
