IPC: F01N3/025
Filed: 1984-03-19
Abstract: PURPOSE:To conduct recycling of a ceramic filter at an optimum condition without causing damage by regulating a high temperature generating burner by using both the temperature of high-temperature gas and differential pressure of the high-temperature between gas pressure measured before and after a ceramic filter. CONSTITUTION:A vessel 5 containing a filter carrier 4 which has caught soot is removed from an engine and placed on a table 17. Next, a burner 16 is ignited. Temperature of combustion gas is measured by means of both a temperature detector 15a and a thermometer 15 and kept at a predetermined value by a temperature regulating device. Combustion gas enters the vessel 5 and makes the soot sticking to the filter carrier 4 burn. Then the gas is discharged via an exhaust pipe 19. While the combustion gas passes through the filter carrier, differential pressure between differential pressure detector parts 14a and 14b is lowered to converge into a constant value soon. This shows that recycling process of the filter is over.

Abstract: PURPOSE:To raise the quality of printing by regulating the time of application of voltage to the same control electrodes in a recording head-driving system in which  voltage is selectively applied to plural recording and control electrodes. CONSTITUTION:Recording electrodes Mj (j is 1-2n) divided into blocks Bi (i is 1-n) are further divided into group MA and group MB by each block Bi. They are faced recording electrodes Sk [k is 1-(2n+1)], shown by Fig. A.

Thus, since voltage is applied twice continuously to each of the control electrodes Sk, as shown by Fig. B, but voltages generated in the low-resistance layer of recording body are smaller on the second application, shown by Fig. C, to counter the problem, the time of the first application of voltage to Sk is made shorter than that of the second application, as shown by Fig. D, so as to equalize voltages generated in the low-resistance layer for both cases, as shown by Fig. E.
