Abstract: This invention provides information to lighten the manager's work load, and to make the staff member accomplish the work in a proper mode. This invention comprises the steps of: based on data received from a terminal of a staff member, registering data concerning the activity state of the staff member and data concerning the settlement state of the problem in the work that the staff member is doing, into the storage device; judging the suitability of the work that the staff member is doing by using a predetermined rule, which is stored in a rule storage, for at least the activity state and the settlement state of the problem, and the data registered in the storage device; and transmitting a manager terminal data representing the suitability of the work that the staff member is doing. Thus, it becomes possible for the manager to do an appropriate judgment without spending time in the information gathering and the analysis.

A frame memory is used for storing the display information corresponding to a display surface of the display unit. There is a window memory for storing the picture information of the window. A control circuit outputs address signal corresponding to the scanning position of the display unit to the frame memory and window memory when the movement or scrolling of the window is detected that the window is moving condition the frame memory and window memory to output the display information and stored in the address represented by the address signal and the picture information in the moving window.

Abstract: Deteriorated positive electrolyte containing Fe.sup.3 /Fe.sup.2+ ions for a redox flow battery is regenerated in a negative electrolyte chamber of an electrolyte regenerating apparatus. For this purpose, a formic acid solution is introduced into a positive electrolyte chamber of the electrolyte regenerating apparatus and a voltage is applied between a negative electrode of the negative electrolyte chamber and a positive electrode of the positive electrolyte chamber, whereby excessive Fe.sup.3+ ions in the deteriorated positive electrolyte are changed to Fe.sup.2+ ions for regeneration. The formic acid is changed into carbon dioxide which is not noxious. All gases generated by the regeneration are not noxious, whereby the regeneration can be carried out with safety.
