The method comprises the steps of : perforating one or more long holes(1) to the length of at least 6m, a cross section area of at least 0.05 m2, and a diameter of 250 - 1000 mm by using a truck(3a), a crane(3b) and a horizontal perforator(3c); perforating a hole(2), for laying an explosive, around a 1st minimum resistance line(W1); blasting the explosive stroke by stroke; perforating again the hole(2) around a 2nd minimum resistance line(W2) wider than the 1st resistance line(W1); blasting the explosive.

Title: Generating circuit for autogain signal of camcorder
Inventor: NOH JAE-KYUNG
IPC: H04N5/243
Filed: 1993-12-15
Granted: 1997-12-01
Abstract: The present invention relates to a circuit generating an automatic gain control signal of brightness and color difference signal. This circuit controls the automatic gain control voltage appropriately and reduces the amount of noise a low illuminance to prevent a screen from being rough. This invention includes a waiting control part setting an automatic gain control region; a buffer keeping a low frequency brightness signal as a signal constant at temperature, and controlling its output by the waiting control part; an integrating part converting the buffer's output into a DC voltage proportional to the low-frequency brightness signal; a comparing part (23) comparing the integrating part's DC voltage with a preset voltage; and a control part producing the automatic gain control voltage of the brightness signal and color signal in response to the comparing part (23)'s output voltage.

Title: Spread spectrum wireless telephone system
Inventor: VANDERPOOL JEFFREY S
IPC: H04J13/00
Filed: 1992-06-02
Granted: 2000-08-01
Abstract: A system for accessing a telephone system (101) in which a set of user stations (102) are matched with a set of base stations (104) for connection to a telephone network (103). Each user station comprises a spread-spectrum transmitter (109) or receiver (108) and is capable of dynamic connection to selected base stations (104). User stations may use CDMA, FDMA, TDMA or other multiple-access techniques to obtain one or more clear communication paths to base stations. Base stations are coupled to each other by means of a private exchange telephone system or other small business telephone system (such as PBX, Centrex, or key type system) so as to couple user stations in calls outside the telephone network. User stations may also be coupled directly or indirectly to the telephone network on their own or by another access path, such as narrowband or spread-spectrum cellular telephone circuits.
