IPC: G01N9/28
Filed: 1991-11-06
Abstract: The invention relates to a process for degreasing and cleaning metal surfaces with tenside-containing aqueous cleaning liquids in baths and/or by spraying. In order to obtain an exact measurement of the bath load and cleaning reserve economically and quickly to allow more accurate subsequent metering of the cleaning agent, the invention proposes that, as a measure of the current reserve of cleaning liquid, a bubble tensiometer is used to measure a value correlated with the dynamic surface tension and operated with a sufficiently constant gas flow, the measurements are compared with a predetermined set value obtained for the cleaning agent used by calibration and, dependently upon the results of comparison, appropriate steps are taken to treat the cleaning liquid.

Title: Method for applying respective colour toner images on light responsive medium - enabling distance or gap between e.g. photosensitive drum and development roller of respective development to be selectively determined
Inventor: SIMAZAKI YUZURU
IPC: G03G15/09
Filed: 1992-09-25
Abstract: A specified voltage is applied between the light responsive drum (1) and the developer roller (2d) of at least one of several developing units. A range for this current flowing between the drum and the roller is determined, between a value which represents an initial contact position (P), in which merely the tips of the magnetic brush (4c) are in contact with the light responsive drum (1) and a predetermined value. The latter value represents a position, in which the magnetic brush (4c) is in complete contact with the drum (1), whilst the degree of contact of the magnetic brush with the drum is altered. A selection is then made of gap (G) between the drum and the developer roller, such that the current (Id) lies in the determined range. ADVANTAGE - Maintains uniform and improved quality of multi-colour image. Degree of contact between light responsive drum and magnetic brush is exactly determined and gap between drum and developer roller is selected according to determined degree of contact.
