摘要： PROBLEM TO BE SOLVED: To suitably and smoothly sense an abnormal combustion using a flame detector without depending upon change of a combustion amount of a combustor by lengthening a delay time for inhibiting sensing of an abnormal combustion state for a predetermined time longer in the case of reducing a combustion amount of the combustor when decreasing degree of combustion amount of the combustor is larger. SOLUTION: A delay time for inhibiting sensing of an abnormal combustion state of a burner by an abnormal combustion sensing means 40 for sensing the abnormal state of the burner is set. During the set delay time, sensing of the abnormal state by the means 40 is inhibited. The means 40 compares a level of a combustion state sensing signal with a reference value response to the combining state of the burner, and senses the state that the level is lowered to a reference level or lower as the abnormal state of the burner. And, a delay time setting means 41 fundamentally sets the delay time longer when decreasing degree of the combustion amount is larger in the case of reducing the combustion amount of the burner. Contrarily, when the degree of the combustion amount is smaller, the time is set shorter.

摘要： PROBLEM TO BE SOLVED: To realize an error type reporting technique using but a single display lamp, easy for the user to comprehend the report and to describe the error orally. SOLUTION: A display lamp is lighted in the 1st display mode when there is an error upon turning-on of an operation start switch, and the mode is switched over to the 2nd display mode after the passage of a specified time length, and the time length is selected according to the error type. This makes it easy for the user to identify the error type and to describe the error. Upon the turning-on of the operation start switch, it is determined whether there is an error or not. Operation is started when there is no error but, if any in presence, operation is not started and the error is displayed. This provides a home appliance easy for the user to understand.

摘要： PROBLEM TO BE SOLVED: To provide a communication unit in which useless power consumption can be avoided during communication. SOLUTION: The communication unit 200 comprises a communication control means 230, and a decision means 240. The communication control means 230 controls power supply to a first communication means 210, and transmission of a first pulse signal to a main communication unit 100. Depending on presence/ absence of a reply from the main communication unit 100 to the pulse signal for the first communication means 210, the decision means 240 makes a decision through which one of a pulse signal (first signal) or a level signal (second signal) communication with the main communication unit 100 is possible. Based on the decision results, the communication control means 230 supplies power to anyone of the first communication means 210 or the second communication means 220, thus bringing about a state communicable through only one of the pulse signal or the level signal.

摘要： PROBLEM TO BE SOLVED: To provide a motor controller which can suppress the deterioration of an efficiency for supplying a power to a synchronous motor and the vibration of the synchronous motor and control a revolution of the motor, at a low cost. SOLUTION: During a half period from a zero-cross point (t0 ) to a next zero-cross point (t1 ) of an output voltage (a) of an AC power supply, the AC power supply is made to be electrically continuous with a motor to apply a voltage to a motor. After an interval of one period (t1 -t3 ) of the output voltage of the AC power supply during a half period from the zero-cross point (t3 ) to a next zero-cross point (t4 ), the AC power supply is made to be electrically continuous with the motor again to apply a voltage to the motor. After an interval of one period (t4 -t6 ) of the output voltage of the AC power supply, the AC power supply is made to be electrically continuous with the motor again. By repeating this procedure, an AC voltage (b) having a frequency (1/T1 ) one third of the frequency (1/T0 ) of the output voltage of the AC power supply is applied to the motor. With such a constitution, the motor can be turned with a revolution synchronizing with a frequency one third of the frequency of the output voltage of the AC power supply.

摘要： PURPOSE:To provide a burning condition determining device, in which the off-set regulation of an operational amplifying circuit can be simplified and the output of electric signal of the operational amplifying circuit never goes out of the range of input voltage of an input port for a microcomputer. CONSTITUTION:Under storing mode, DC voltage of a predetermined level is impressed under a condition that a thermocouple 1 is not connected while a microcomputer 5 operates a correcting value by (predetermined voltage- recognizing value) and stores it into an E PROM 4. Under ordinary operation mode, the microcomputer 5 reads the correcting value out of the E PROM 4 to convert it into a correcting value and sends an output 50 for off-set coping with said correcting value out of a D-A output port 52 to impress it on both ends of a resistor 26 through another resistor 53 and effect off-set.
