A process is provided for producing peroxycarboxylic acids from carboxylic acid esters. It has an elongate reservoir body with an open upper end, a closed lower end, and a central cavity enclosed by an encircling wall. It is desirable that a dielectric film formed in a metal wiring layer under the uppermost layer and a supplementary capacitor composed of a storage node and a plate electrode are connected to the capacitor. The event and the importance level of the job affected by the event is displayed in the IMU. Finally a linear curve fit between one and K+Ct over the range of +\u2212 sets the remaining values for the graticule.
