摘要： PURPOSE:To reduce fluctuation of thickness of ceramic honeycomb and to reduce permeation resistance to waste gas by electrodepositing ceramic particles to a honeycomb structure comprising electroconductive sheet material and calcining the honeycomb structure to form a ceramic honeycomb. CONSTITUTION:A lead wire 2 is attached to a honeycomb structure 1 comprising an electroconductive sheet material, and the structure is dipped in a thermostat 4 filled with ceramic slurry 3. Ceramic particles are deposited to a specified thickness to the surface of the sheet material of the honeycomb structure 1 by the electrophoresis by impressing DC voltage from a DC source 6 to a counter electrode 5 between the lead wire 2 and 7. The honeycomb structure deposited electrically with ceramic particles is dried and calcined to obtain the ceramic honeycomb. The sheet material is eliminated during calcination and ceramic particles alone are sintered.

摘要： PURPOSE:To detect the condition of fuel correctly and permit to heat the fuel properly by a method wherein the heating of the fuel is effected based on a fuel temperature signal, outputted by a temperature sensor, and a pressure signal, outputted by a pressure sensor for detecting the clogging of a fuel filter. CONSTITUTION:A control circuit 26 inputs the fuel temperature signal 100, outputted by the temperature sensor 22, after starting the engine 10 by putting a key switch 32 ON under a low temperature and conducts a fuel heater 20 while the fuel is heated for a predetermined period of time under an idling revolution. Next, when the engine is brought into running condition, the control circuit 26 inputs the pressure signal 102, outputted by the pressure sesor 24 detecting the clogging of the fuel filter 18, controls the fuel heater 20 based on the pressure signal and the temperature signal 100 and prevents the fuel from becoming wax or the clogging of the fuel filter 18. Accordingly, in case the temperature of the fuel is higher than a predetermined temperature, the heating will never be effected as fas as the pressure of the fuel from the fuel filter does not become lower than a predetermined pressure and thus useless heating may be prevented.
