Title: Combustion control device
Inventor: HONDA GOJI
IPC: F23N5/20
Filed: 1998-09-07
Abstract: PROBLEM TO BE SOLVED: To enable a target temperature at a time when a user desires, eliminate a waiting time from a timer set time at a conventional combustion control device until the time when the target temperature is obtained, and correspond to a temperature change at the time of apparatus combustion starting time so as to improve the user's operability. SOLUTION: A user sets the time when a set temperature is wanted to be obtained. A temperature deviation calculating part 9 calculates the deviation between the set temperature set by the user and a temperature input obtained by a temperature detection part 12 only a set time of a combustion operation determining timer 8 earlier than the set value. A combustion starting timer 13 selects a preset value based on a necessary combustion time for increasing the temperature only by the deviation amount and calculates the time. The target temperature is more correctly obtained at the time when the user desires by commanding the starting of the combustion after the completion of the time calculation, that is, only the combustion time necessary to increase the temperature by the temperature deviation amount earlier than the time when the user wants the set temperature.

Abstract: PURPOSE:To reduce the space and cost to less than two times by a method wherein three sets or more of power source units are connected in parallel and when one set among them is troubled, the backup of the faulty unit is effected by the remaining power source units. CONSTITUTION:Three sets of power source units A1, A2, A3, for example, are connected in parallel and current is supplied to a load B by three sets of power source units A1, A2, A3. When one set of power source unit A1 is troubled, remaining two sets of power source units A2, A3 supply current to the load B to maintain the operation of the load B. The output current capacity of one set of the power source unit becomes 1/2 of a total load current. The total output current capacity of three sets of power source unite A1, A2, A3 becomes 1.5 times (1/2X3) of the total load current or less than two times of the same. The total output current capacity of power source units A1-AN becomes N/(N-1) generally whereby space saving as well as cost saving may be effected.

Abstract: PURPOSE:To control the temperature difference between an object body and ambient air to a fine value electrically by providing a thermoelectric element to a discharge pipe inserted into the object body and charging a fluidized bed in the gap between the discharge pipe and object body. CONSTITUTION:The air at the periphery of a honeycomb 3 is sucked at an extremely low flow rate through the rotation of a blower coupled with the base end of the discharge pipe 4 to pass through particle gaps of the fluidized bed 3 from a dispersing plate 6 and further flows in the discharge pipe 4 from a filter 7 at the upper end of the discharge pipe 4 as shown by an arrow, so that the air is discharged. When the air is sucked in the honeycomb 3 from the dispersing plate 6, particles in the fluid layer 8 are flowed. When the temperature of the honeycomb 3 is higher than target temperature, particles in the fluidized bed absorb heat from the honeycomb 3 with high heat conductivity and radiate the heat to the thermoelectric element 9 provided to the outer periphery of the discharge pipe 4 through fins 11. When the ambient air is discharged through the inside of the discharge pipe 4, a heat exchange is made again by the thermoelectric element 9 through inner peripheral fins 10, so that the discharge air is heated.
