摘要： PROBLEM TO BE SOLVED: To provide a non-open-cut construction method capable of laying feed pipes at a required position with space-saving and a short term construction. SOLUTION: In the non-open-cut construction method in which a feed pipe branched off from an underground main branch pipe to consumers is laid without open-cutting, a pit leading from the ground to the main branch pipe is dug and a detecting means detecting information about the position of the main branch pipe is placed in the pit. A propulsion means driving an excavation means which excavates a guide hole for insertion of the feed pipe is installed on the consumer side. The drive of the propulsion means is controlled based on the position information of the detecting means. The guide hole is formed by propelling the excavation means, and a flexible sleeve is moved to the pit while enlarging the diameter of the guide hole. After the excavation means is pulled out from the flexible sleeve, a resin feed pipe having a resin joint on the end is inserted into the flexible sleeve. The resin joint is connected to the main branch pipe and a piercing means is passed through the feed pipe to connect the main branch pipe and the feed pipe. After gas leakage at the junction is ascertained, the flexible sleeve is pulled out, and the pit and the place around the feed pipe is buried again. COPYRIGHT: (C)2003,JPO

摘要： PURPOSE:To carry out securely a count processing for every one by providing a groove-shaped feeder resiliently supporting and exciting a grooved lane for mounting and carrying a counting abject, and an inclined chute having a dropping gradient and counting the dropping object. CONSTITUTION:A counting object charged in a hopper 1 is supplied to a groove- shaped feeder 5 consisting of lanes 51-53 having V-shaped section provided with vibrators 54, 55 disposed at a lower section of the lane by way of a large volume feeding feeder 41, a large volume feeding and a fraction adjusting feeder 42 through a feeding feeder 2, a feeding conveyor 3. In the side sections of the respective lanes 51-53, suitable number of counting object arranging blocks 56 are-disposed and advancing counting objects are arranged in a row by a vibration of the lane. The counting object exceeding an end block 57 disposed at a final end moves to an inclined chute 6 and drops lanes 61-63 by a gravity. The speed at this time is substantially faster then that of a preceding stage so that the counting object is effectively separated and counted.
