Title: Process for forming molten salt corrosion-resistant surface of incinerator
Inventor: ONO SHOZO
IPC: F23G5/44
Filed: 2002-06-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide a safe, easy process for forming a high-temperature corrosion-resistant surface of an incinerator wherein a silicon dioxide coated film can sufficiently exert its effect by preventing decrease in workability of a material to be treated.  <P>SOLUTION: A silicide-diffused layer or a silicon dioxide-coated layer is formed on the surface of a metal for the incinerator by maintaining the metal material to be treated, which has a mixed slurry of silicon and silicon dioxide applied thereto or implanted therein, in an inert gas at a predetermined, elevated temperature. This method enables to prevent decrease in workability which occurs when silicon is used alone and form a modified layer having a fine surface with few irregularity. Here, the temperature is preferably controlled to 1,000-1,250°C. Since addition of sodium fluoride to the mixed powder activates silicide formation, the diffused layer having a thickness of ≥100 μm can be formed, even at a low temperature of ≤1,000°C. Use of a fine particle with a powder grain size of ≤1 μm increases area of contact with the metal and improves efficiency of surface treatment.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To prevent reduction in boosting efficiency to a fuel injection system by securing valve closing driving of a solenoid opening-closing valve in duty control even if source voltage drops when a rotational phase of an internal combustion engine is unclear in a high pressure fuel supply device of the internal combustion engine.  <P>SOLUTION: When the rotational phase of the internal combustion engine is unclear at starting time (YES in S100), the duty control is performed (S104), and current-carrying time is lengthened as battery voltage Vb becomes low in this duty control (S102). Thus, the solenoid opening-closing valve can be surely closed particularly in a pressurization stroke so that the purpose is attained. Since the current-carrying time in the duty control is shortened when the battery voltage Vb is high, an unnecessary increase in a load to an electric circuit can be prevented.  <P>COPYRIGHT: (C)2004,JPO
