Disclosed are an electrode active material, having a composition of SnPx (0.9≦x≦0.98), an electrode comprising the same, and a lithium secondary battery comprising the electrode. Also disclosed is a method for preparing an electrode active material having a composition of SnPx (0.9≦x≦0.98), the method comprising the steps of: preparing a mixed solution of a Sn precursor, trioctyl phosphine (TOP) and trioctyl phosphine oxide (TOPO); and heating the solution. The application of the teardrop-shaped single-crystal SnP0-94 particles as an anode active material for lithium secondary batteries can provide an anode having very excellent cycling properties because the active material has a reversible capacity, which is about two times as large as that of a carbon anode, along with a very low irreversible capacity, and it is structurally very stable against Li ion intercalation/deintercalation in a charge/discharge process, indicating little or no change in the volume thereof.

A driving device of a light source for a display device is provided. The light source includes a plurality of lamps connected in parallel to each other and each lamp has a first terminal and a second terminal. The driving device also includes a lamp state sensing unit sensing driving voltages applied to the respective lamps, comparing the sensed driving voltages to a reference voltage, and outputting a lamp state sensing signal having an information informing an over-current state for at least one lamp; and an inverter turning the lamps on or off by applying an AC voltage to the lamps and controlling the AC voltage based on the lamp state sensing signal. The reference voltage is varied depending on the magnitude of the driving voltages applied to the respective lamps.

An apparatus for manufacturing a semiconductor device includes a rotatable spindle, a head detachably connected to the spindle, and a clamp for clamping outer circumferential surfaces of the spindle and the head to one another so that the head may be driven by the spindle. The clamp has an annular clamping frame sized to encircle the outer circumferential surfaces of the spindle and the head, a projection disposed on one end of the clamping frame, a lever pivotally connected to the other end of the clamping frame, and a fastener pivotally connected to the lever and configured to hook over the projection. Once the fastener is hooked over the projection, the lever is pivoted to force the ends of the annular clamping frame together and thereby produce a clamping force that secures the spindle and head to one another. The clamp can be manipulated easily and with a simple motion to clamp the head to the spindle. Also, the parts of the clamp generate little mechanical friction. Accordingly, the head can be quickly connected to and disconnected from the spindle, and such operations will not produce particles that could contaminate the semiconductor wafer.

The present invention relates to a compressor, wherein a rotary shaft 140 having a swash plate 144 coupled thereto is used to linearly reciprocate a piston 150 in a cylinder bore 134 formed in front and rear cylinder blocks 130 and 130′. The rotary shaft 140 has a flow channel 142 formed therein and inlets 142a formed to communicate with the flow channel 142. A hub 146 is formed in the swash plate 144, and a shaft hole 146a, through which the rotary shaft 140 passes, is formed in the center of the hub 146. Communication holes 146b are formed in the hub 146 to communicate with the inlets 142a of the flow channel 142. First races 148a are coupled to the hub 146. A rotary shaft hole 148d is formed in the first race 148a, which has a thickness greater in its outer peripheral portion than its inner peripheral portion. According to the present invention configured as above, the communication holes 146b are concavely formed in surfaces where inlets of the shaft hole 146a of the hub 146 are provided, so that the communication holes 146b can be formed together with the hub. Thus, there is an advantage in that the compressor can be easily manufactured. Also, the first race 148a has a thickness greater in its outer peripheral portion than its inner peripheral portion. Accordingly, there is an effect in that the strength of the first race 148a can be reinforced while keeping its damping effect, thereby improving durability of the swash plate type compressor.
