摘要： A variable capacity rotary compressor capable of reducing collision noise of a vane with a roller. The variable capacity rotary compressor includes a vane controller controlling the operation of a vane in order to vary compression capacity. The vane controller includes a control valve that switches a fluid channel so as to selectively apply discharge pressure and intake pressure to the vane guide slot, a connection channel that connects the control valve with the vane guide slot, a high-pressure channel that connects the control valve with a discharge side of the compressor, and a low-pressure channel that connects the control valve with an intake side of the compressor, and a throttle section that reduces the fluid channel of at least one of the high-pressure channel and the connection channel in order to reduce an initial discharge pressure applied to the vane guide slot.

摘要： A power supply apparatus for LED is provided. The power supply apparatus for LED includes a transformer, a first output unit, and a second output unit. The transformer includes a primary winding, a secondary winding receiving a power induced from the primary winding, and a tertiary winding receiving the power induced from the primary winding. The first output unit is connected to the secondary winding of the transformer, and outputs a first power current to an LED in a first operating condition. The second output unit is connected to the tertiary winding of the transformer, and outputs a second power current to the LED in a second operating condition. When the LED is connected to the power supply apparatus for LED, the power supply apparatus allows a current equal to or less than a predetermined current to flow in the LED, thereby protecting the LED from an overcurrent.
