Object-zone extraction section 12 receives image information through image input terminal 11 and extracts object zones from the received image information. The method comprises forming on the surface an exposed pattern of colloid particles, corresponding to the conductor pattern to be formed. When the applied pressure reaches the pressure setting of the relief valve, the valve opens to apply air sidewardly in bursts which create shock waves to dislodge built up material from the well screen and the surrounding filter pack and formation fractures. The movable contact piece which is formed by a rod-shape conductive spring member, and the movable contact portions at both ends of the movable contact piece are slidably disposed to the fixed contact portions. The housing is transversely flexible relative to the balance shaft to accommodate misalignment of the intermediate bearing relative to the front and rear end bearings. Also included are methods of treating lipdystrophy by decreasing GATA-2 or GATA-3 expression.
