Title: Kerosene warm-air heater
Inventor: KAWABATA JUNICHI
IPC: F24H3/04
Filed: 1989-01-31
Abstract: PURPOSE:To purify the air in a room with ozone in the course of a heating operation while making it circulate therethrough, by a method wherein part of the air taken in a heater is subjected to sterilization and purification with ozone and returned into the room. CONSTITUTION:Part of air taken in a heater by an air intake fan 10 through a filter 11 in the course of a heating operation is made to branch into a supply channel 12 of air for purification from a supplier 6 of air for burning, and part of the branched air is turned to be ozone by an ozone generator 13 and mixed with the remaining air for purification in a mixing chamber 14. In the mixing chamber 14, sterilization and purification of air are executed by the chemical properties of the ozone. The air mixed with ozone, having been subjected to the sterilization and the purification, is sent further into the upper part of a combustion chamber 3 from the mixing chamber 14 through a leadout pipe 15 and the residual ozone is decomposed therein by a heat from the combustion chamber 3. The ozone being decomposed, the air subjected to the sterilization and the purification returns into a room from a warm-air outlet port 16. Since the ozone is not decomposed when a temperature in and near the combustion chamber 3 is low, the operation of the ozone generator 13 is kept in a stopped state for a proper time after the start of combustion through the intermediary of an operation control element 18.

Abstract: PURPOSE: To improve the operation performance of an internal combustion engine by securing a correct signal all the time by sampling a signal and by finding and outputting the mean value of a fixed number of sampled values among stored sampled values (a constant number of values).  
     CONSTITUTION: Signal S 1  of the sensor Karman-vortex flow meter of an internal combustion engine is waveform-shaped 1 to obtain pulse S 2  of a period in inverse proportion to how much air is sucked, and clock pulses S 3  from clock generator 3 are counted 2 to output signal S 4  in proportion to each period of signal S 2 . Next, shift register 4 is stored with count values as many as four periods of signal S 4  at  any time and every time a new count value is supplied, the contents of register 4 are updated; and signal S 5  from each stage of register 4 is inputted to averaging circuit 5, which sends mean value S 6  to a controller as a suched-air volume signal. Thus, the mean value of values covering four periods of signal S 2  can be obtained, so that even if an abnormal value due to a noise, etc., would mix, its error will lessen by averaging.
