Abstract: An air hammer for a boring machine includes a main body, a first bushing member, a second bushing member installed at an end on the opposite side of the main body, a bit unit installed at an end of the second bushing member, a piston hammer, a pneumatic discharge part formed at the top end of the second bushing member, and a pneumatic pressure distribution part formed on the piston hammer.

Abstract: The branching apparatus according to the present invention includes two power supply terminals mounted on a saddle in the opposite direction of a branch connection part branched from a cylindrical body, so that they are not overlapped with the branch connection part when an electric socket is connected to the power supply terminal, and hence, it provides easiness in work. Moreover, because the branch connection part is slantly mounted directly above the main pipe, a trace wire inserted into the branch connection part and the main pipe is not bent, and hence, the trace wire can trace exact length and position.

Abstract: An air hammer for a boring machine is provided, including: a main body including a hollow portion; a socket coupled to a side of the main body; a first bushing member including a sealing part coupled to the main body and a piston guide part extending from the sealing part in parallel with a lengthwise central axis of the main body and defining an air supply passage and discharge holes in an outer surface thereof to communicate with the air supply passage; a second bushing member installed at an end on the opposite side of the main body; a bit unit installed at an end of the second bushing member; a piston hammer, top and bottom ends of which are supported by the guide part and the second bushing member so as to be moved up and down, the piston hammer having a guide hole formed therethrough in the lengthwise direction and partitioning a main body compartment between the first and second bushing members into first and second chambers; a pneumatic discharge part formed at the top end of the second bushing member

Abstract: A call processing method and a mobile terminal are provided. The mobile terminal includes a Radio Frequency (RF) receiver including a first input terminal connected to a first incoming signal line and a second input terminal connected to a second incoming signal line, a first RF switch arranged on the first incoming signal line for switching the first incoming line between the first input terminal and an inter-switch line, a second RF switch arranged on the second incoming signal line for switching the second input terminal between the second incoming signal line and the inter-switch line, and a controller for controlling, in a data call session, the first RF switch and the second RF switch to establish a connection of the first incoming signal line and the second incoming signal line during a first period and during a second period.

Abstract: Voice dialing is performed through an ear-microphone in a mobile terminal with an ear-microphone, having a voice dialing function. The mobile terminal enters a voice dial mode, upon receipt of key data generated by user's pressing a specific key positioned on the ear-microphone, and outputs an outgoing message for performing voice dialing. After outputting the outgoing message, the mobile terminal sequentially demodulates voice data for voice dial phone numbers and outputs the demodulated voice data. The mobile terminal dials a voice dial phone number selected by the user during the output of the voice data.
