Title: Heat detection circuit
Inventor: TSUTSUMI TAKESHI
IPC: G01K7/24
Filed: 1988-10-31
Abstract: PURPOSE:To arbitrarily set the temp. of a heating element by detecting the heat of the heating element by a heat-sensitive element and changing a voltage level on the basis of a change of the heating element and comparing said level with a preset level to output a detection signal. CONSTITUTION:The voltage of a point (a) determined by the resistor 2A and a positive temperature coefficient thermistor 2B of a level detection part rises with the temp. rise of a heating element 1 to be inputted to the + input terminal of a comparator 3C. The voltage of a point (b), determined by the Zener diode 3B of a comparing part, inputted to the - input terminal of the comparator 3C is always a constant value and the comparator 3C compares the voltages of the points (a), (b) to set an output terminal to an 'H' level. The detection signal of the 'H' level is outputted to a control part 4 which in turn controls the heat of the heating element 1 on the basis of the detection signal of the 'H' level.

Title: Heat exchanger
Inventor: IKETANI JITSUO
IPC: F28F17/00
Filed: 1992-10-12
Abstract: PURPOSE:To enable effective prevention of frosting by a method wherein the ratio between the width in the direction of draft of the part of a radiator fin provided with a heat exchanger pipe and the overall width in the direction of draft of the radiator fin is set in a specified range. CONSTITUTION:A plurality of heat exchanger pipes 1 are stacked in a plurality of layers in the same direction in a state of being parallel to the direction (a) of draft by a strip-plate-shaped radiator fin 5 being long in the direction of height. The ratio between the overall width W2 of this radiator fin 5 and the width of the part of the radiator fin 5 provided with the heat exchanger pipe 1 is set to be W2/W1=1.2 to 1.9. Since the windward-side end part 5a is continuous in the vertical direction according to this constitution, a drain condensing on the surface of the radiator fin 5 is discharged easily onto the lower side of the radiator fin 5 through this end part before frosting on this part. Therefore the frosting can be prevented effectively and the capacity of heat exchange can be maintained excellently.

Filed: 1989-10-20
Abstract: PURPOSE:To prevent a combustion failure or the generation of an abnormal noise due to inappropriate substantial air/fuel ratio by making a correction at the side where the flow rate of air for combustion is relatively increased with respect to the feed quantity of a gas fuel, on the ratio adjustment of an adjustment means during a period until the combustion operation of a burner is brought into a steady state from a point of time when the combustion operation is started. CONSTITUTION:A correction unit 4B allows an air/fuel ratio adjustment unit 4A to execute an adjustment of air/fuel ratio on the basis of correction correlation l', which is additionally set on the increasing side of the number of rotations of a fan, instead of reference correlation l, during a preset period of time [e.g. one minute or so] from the moment of starting the combustion operation of a burner 2 [i.e. a point of time when the burner 2 is ignited in response to a water flow rate detected by a water flow rate sensor 8]. By this method, a correction on a side where the flow rate 'v' of air for combustion with respect to the feed quantity 'g' of a gas fuel is increased more than that at the time of a normal air/fuel ratio adjustment based on the reference correlation l, is added to the air/fuel ratio adjustment at the air/fuel ratio adjustment unit 4A during the preset period of time.
