Abstract:
A centrifugal fan includes: an impeller; an upper casing that is disposed above the impeller; a lower casing that is disposed below the impeller; an outlet port that is provided between the upper casing and the lower casing and from which an air suctioned by rotation of the impeller is discharged, wherein the upper casing is provided with a flange that protrudes in an outer radial direction of the impeller from an outer circumferential edge of the upper casing, and wherein the flange partially covers the outlet port when viewed from a direction perpendicular to a rotation axis of the impeller.
Abstract:
A control method for a vibration generator is provided. The vibration generator includes a fixed part around which a coil is wound, a movable part having a magnet, a bridge part movably supporting the movable part, and a power supply unit which applies an alternating current of a predetermined frequency to the coil. The power supply unit starts at the time of startup by the alternating current with a starting frequency which differs from a resonance frequency of the movable part, and the power supply unit changes the frequency of the applied alternating current to the resonance frequency of the movable part when the amount of vibration at the starting frequency reaches a predetermined ratio with respect to a saturation vibration amount of the resonance frequency.
Abstract:
A load driver includes: a rectifying unit configured to rectify an AC voltage from a power source to generate a first voltage; a first converter configured to convert the first voltage outputted from the rectifying unit into a second voltage; a second converter configured to drive a load with a constant current, based on the second voltage converted by the first converter; and a feedback unit configured to generate feedback information, based on information obtained from the second converter and indicating an output voltage when the second converter drives the load with the constant current, wherein the first converter converts the first voltage into the second voltage having a magnitude based on the feedback information obtained from the feedback unit.
Abstract:
