摘要： PURPOSE:To keep a stable combustion state even during weak combustion and perform continuance of combustion without the occurrence of halfway combustion by a method wherein limitation is applied on a combustion width according to an altitude and combustion is performed within a range where a combustion state is not brought into instability. CONSTITUTION:When an altitude setting means 16 is not brought into setting of an altitude, combustion is continued as it is. When the altitude setting means 16 is brought into altitude setting, an ON time of an ON/OFF pulse signal applied on an electromagnetic pump 2 is set to a TON high value corrected by an altitude correction means 15. A heat generation amount corresponding to the number of revolution of a motor 3 measured by a number of revolutions detecting part 12 is imparted on the correction amount of the TON high value. It is then discriminated whether the objective number of revolutions of the motor 3 is lowest. When it is not lowest, combustion is continued and when it is a lowest rank 1, the target number of revolutions is increased to a rank 2. By re-correcting a combustion feed amount, and as a result, a combustion width is limited so that, in the objective number of revolutions, the rank 2 forms lowest combustion and combustion of the rank 1 is not executed.

摘要： PURPOSE:To essentially improve the safety of the apparatus, in an electromagnetic pump-controlling apparatus for a combustion machine burning a liquid fuel. CONSTITUTION:A conbustion-controlling part 11, a pulse-generating part 12 generating a pulse on the basis of output from the combustion- -controlling part 11, an electromagnetic pump-driving circuit 6 driving an electromagnetic pump 7 on the basis of the pulse from the pulse-generating part 12, and a source pulse-generating circuit 13 generating a source pulse synchronized with a commercial electric source, are provided, and the pulse-generating part 12 generates the pulse on the basis of a cycle of the source pulse outputted from the source pulse-generating circuit 13. In this way, even if the clock frequency of a microcomputer increases because of malfunction or the like, such a trouble that the amount of fuel supply increases does not occur, and thus a safe apparatus having no fear of danger such as a fire can be provided.

摘要： PURPOSE:To obtain a controller for a heater which has a convenient backup function, such as processing of clock-related information, with a high reliability. CONSTITUTION:A controller contains a program for controlling a heating machine, a controlling microcomputer 3 which works only when commercial source power 1 is impressed, and a program for the clock-related processing. The controller is equipped with a submicrocomputer 11 which, when the commercial source power 1 fails, works by a backup power such as the power from a battery 8, a resetting means which, when the commercial source 1 is impressed, resets the controlling microcomputer 3, a data-reading means by which, immediately after the resetting, the submicrocomputer 11 reads data, a data- writing means which, during operation, transfers data to the submicrocomputer 11 to make the data stored as desired.

摘要： PURPOSE:To obtain a needle controller of a vaporizing type combustion apparatus where tar deposited on a nozzle hole can be cleaned when necessary. CONSTITUTION:Switches 29, 30, 31 and 32 are built in a combustion apparatus to control a variety of functions. When at least specified two or more of those switches are operated simultaneously during non-combustion period, a solenoid 14 is energized according to a program of a microcomputer 21 and a needle is controlled corresponding to energizing of the solenoid 14 so as to open or close a nozzle hole. Therefore, tar deposited on the nozzle hole can be cleaned when necessary except for the combustion period without an increase in production cost.
