Abstract: An amplifying circuit includes a feedback resistor (RA), and amplifies a voltage that is proportional to a current detected by a current detection resistor (R1) with a gain depending on the feedback resistor (RA). A current control circuit (IC) controls the current flowing through a Peltier element in such a manner that the amplified voltage (VA) output by the amplifying circuit is kept constant. The feedback resistor (RA) includes a thermistor and a fixed resistor (R2) connected to the thermistor in series.

Abstract: Effective component generation device includes internal components, case, and air passage member. Air passage member is housed in case and surrounds discharger. Air blower of internal components generates air flow that outputs an effective component to the outside. Air passage member has upstream block and downstream block. Upstream block forms air supply passage on the upstream side. Downstream block forms air discharge passage on the downstream side. Air passage member includes air supply passage and air discharge passage in case, and forms air passage through which air flow passes. This provides effective component generation device capable of efficiently generating air flow that outputs an effective component to the outside of case.

Abstract: A fan control system according to the present disclosure includes a controller that selects a control mode from a plurality of control modes including a first mode and a second mode. The first mode is a control mode in which an electric signal is given to fan motor so that fan motor operates at the first rotation speed. The second mode is a control mode in which an electric signal is given to fan motor so that fan motor operates at a second rotation speed lower than the first rotation speed. The controller has a function of selecting the second mode in a period after the start of the fan motor and before the selection of the first mode.

Abstract: Effective component generation device includes internal component and case. Internal components include discharger that generates an effective component. Case is formed in a box shape having discharge port through which an effective component is discharged, and houses internal components. Case includes metal body including a bottom plate and peripheral walls surrounding at least discharger in internal component. Metal body has seamless portion at a corner portion between two surfaces of adjacent peripheral walls oriented in different directions. As a result, there is provided effective component generation device capable of suppressing electromagnetic noise radiated to the outside of case and reducing an influence of electromagnetic noise to the outside.
