摘要： The present invention relates to a hydrant system that is projected over the ground while being buried in the underground. The hydrant system comprises a sluice valve (20) connected to a water-guide tube (10) within a manhole M, the sluice valve having a first openings/shutting shaft (21) disposed therein; a female cylinder (30) having a drain valve (31) that is opened when the sluice valve (20) is locked and that is locked when the sluice valve(20) is opened, and a bracket (36) having a through-hole; a male cylinder(40) having a piston(45) for opening/shutting the bottom of the male cylinder(40) as a piston rod (44) is rotated in the forward or reverse direction; a rod(50) for limiting a projection range of the male cylinder(40) protruded against the female cylinder (30); a manhole cover (60) having a sub hole (62) through which the male cylinder (40) passes; a second opening/shutting shaft (61) for rotating the first opening/shutting shaft (21); and a universal joint (70), which connects the first opening/shutting (21) and the second opening/shutting shaft (51).

摘要： A fusible resistor and method of fabricating the same is provided. The fusible resistor has a very low resistance of 20 to 470 mΩ by depositing thin films as a fusible element made of a material with low resistivity such as copper having a temperature coefficient of over 2,000 ppm/° C. The fusible resistor comprises a resistor body, a fusible element layer formed to surround the resistor body, caps formed to surround ends of the fusible element layer, lead wires attached to the caps, and an insulating layer for insulating the fusible element layer and the caps from outside. The thus-fabricated fusible resistor performs all functions of a use without generating excessive heat.
