    摘要： When the control unit makes both the first and second inverter circuits operational, the control unit controls the first and second inverter circuits by duty control such that an average heating output from the first inverter circuit reaches a predetermined first target heating output, and an average heating output from the second inverter circuit reaches a predetermined second target heating output. When the control unit makes one of the first and second inverter circuits operational in an automatic heating mode for automatic heating control according to a predetermined heating output sequence, the control unit inhibits the first and second inverter circuits from being controlled by the duty control.

    摘要： When a flow rate is equal to or more than a reference flow rate, a reference voltage is changed to a level capable of measuring stably to thereby realize the improvement of measurement accuracy at the time of a large amount of flow rate. A flow rate determination means compares a flow rate calculated by a flow rate calculation means with the reference flow rate. When the calculated flow rate is larger than the reference flow rate, the reference voltage set by a reference voltage setting means is changed, whereby the zero cross point can be detected stably at the portion where the degree of the influence of the change in the amplitude of the received signal is small. Thus, it is possible to provide a flow rate measuring device capable of measuring a flow rate stably with high accuracy even when a fluid flow is disturbed due to a large amount of flow rate.

    摘要： An induction heating device includes: a rectifying circuit that rectifies an AC power supply; a smoothing capacitor that smooths the rectified output to obtain a DC power supply; a first and a second inverters each composed of a heating coil, a resonance capacitor, and a switching element, and connected to the smoothing capacitor in parallel; a first and a second oscillating circuits that supply drive signals to the switching elements; and a controller that controls drive of the first and second oscillating circuits. The controller alternately drives the first and second oscillating circuits, and controls a drive time ratio of the first and second oscillating circuits so that a power change amount generated every time the drive is switched between the first and second oscillating circuits is not more than a predetermined amount.
