Abstract: An actuator apparatus for a clutch that operates the clutch of a transmission according to operation of a motor, may include the motor including a stator and a rotator, wherein the rotator has a drive shaft and a rotator core receiving the drive shaft therein, a lead screw engaged to the drive shaft of the motor and movable in a length direction thereof according to the operation of the drive shaft in the motor, a rod disposed apart from the lead screw, a slider connecting the lead screw with the rod, and a guide rail disposed to contact with the slider and guiding a linear motion of the slider.

Abstract: A clutch actuator for a vehicle includes a lifting member having a first end connected to a power generator, a middle portion provided with a hinge point, and a second end formed with an inclined plane, the lifting member being linearly moved by receiving a power from the power generator; a guide member provided at one side of the second end of the lifting member to rotate the second end of the lifting member around the hinge point as the lifting member is linearly moved while the inclined planes are supported; and a lever provided at one side of the lifting member and having a first end thereof supported by a clutch housing and a second end rotating around the first end by being pressed by the lifting member according to the movement/rotation of the lifting member, to engage with or release a clutch.

Abstract: A clutch actuator unit is provided that includes a housing having a mounting space and a penetration aperture for receiving an operating rod. A slide pad and slider are disposed along an inner side surface of the mounting space, and are configured to move back and forth within the housing. An operating rod that is connected to the slider through the penetration aperture is moved back and forth, along with the slider and slide pad, through the aperture via a drive portion. A stopper is also integrally formed along the front surface of the slide pad to limit the movement of the slider accordingly. In doing so, the disclosed actuator is able to dynamically locate certain stroke positions and provide an improved shifting operation.

Abstract: The present invention relates to a directional coupler, in particular, to a capacitance compensation type directional coupler comprising a signal line for transmitting signals. A coupling line is formed apart from and parallel to the signal line, with its first end transmitting the extracted power and its second end terminated. At least one conductive line, electrically connected to the coupling line, is extended from the coupling line across the signal line, apart from and perpendicularly overlapping with the signal line. The present invention compensates capacitance between the signal line and the coupling line by forming capacitance in areas where the conductive line and the signal line overlapping each other perpendicularly.

Abstract: Disclosed herein are a directional coupler which is implemented with strip lines for signal coupling and inter-digital capacitors for phase compensation, and a dual-band transmitter using the same. The directional coupler includes a first transmission device, a first directional coupling device for coupling a part of a signal from the first transmission device, a first inter-digital capacitor connected between the first transmission device and the first directional coupling device, a second transmission device, a second directional coupling device for coupling a part of a signal from the second transmission device, and a second inter-digital capacitor connected between the second transmission device and the second directional coupling device.

Abstract: The invention provides a dual band transmitter available for a mobile communication terminal such as mobile phone, in which a first RF amplifier 111 amplifies the power of a high band signal BS1 at a first amplification factor that is determined according to a first bias voltage. A second RF amplifier 121 amplifies the power of a low band signal BS2 at a second amplification factor determined according to a second bias voltage. A first coupling capacitor C11 couples an output signal from the first RF amplifier 111. A second coupling capacitor C21 couples an output signal from the second RF amplifier 121. A filtering coupler 140 has a high pass filter FT1 for a first coupled signal from the first coupling capacitor C11 and a low pass filter FT2 for a second coupled signal from the second coupling capacitor C21.
