20100214984 | METHOD FOR RANDOM ACCESS PROCESS IN MOBILE COMMUNICATION SYSTEM - The present invention relates to a method for a random access process in a mobile communication system. According to the exemplary embodiments, in the case where a mobile terminal requests a random access to a network, when the network is not able to promptly allocate a resource for the random access to the mobile terminal due to an insufficient resource, the mobile terminal is maintained in a standby state without repeatedly requesting the random access to the network. Accordingly, it is possible to reduce the uplink signal interference caused by the repeated random access request, reduce the possibility of communication contention between the mobile terminals for the access to the mobile communication system, and reduce the power consumption of the mobile terminal. | 08-26-2010 |

20080237407 | Structure for fixing reducer for sprinkler in side wall - Provided is a structure for fixing a reducer for a sprinkler in side wall construction, which includes a bracket, a reducer, and an adjusting bolt. The bracket includes a first transverse portion, a first longitudinal portion, a second transverse portion, and a second longitudinal portion. The first transverse portion includes an elongated hole formed in order to be fixed on a ceiling with at least one fixing member. The first longitudinal portion is bent perpendicularly with the first transverse portion at one end of the first transverse portion. The second transverse portion is formed in parallel with the first transverse portion on the bottom of the first longitudinal portion, in which a rail hole is formed in the plate surface thereof. The second longitudinal portion is formed in parallel with the first longitudinal portion at the end part of the second transverse portion, in which a screw tap is formed in the plate surface thereof and simultaneously a through-hole is formed in one side of the rail hole. The reducer includes a rail block and a plate. The rail block is formed into a linear type tubular body with one end of which a flexible tube is combined and with the other end of which the head of the sprinkler for side wall construction is combined. The rail block is arranged in parallel with the second transverse portion at the lower portion of the second transverse portion, and is protruded from the upper-center portion of the reducer, in which sliding grooves formed in the rail block are engaged with a rail hole formed at the second transverse portion to thereby allow the rail block to move in the form of a rail. The plate is arranged in parallel with the second longitudinal portion at the location spaced from the rail block, in which a through-hole is formed in the plate surface. The adjusting bolt is inserted into the through-hole of the plate and is screwed into a screw tap of the second longitudinal portion, to thus enable the reducer to reciprocate in the direction which is in parallel with the second transverse portion during forward and backward rotation. In this way, since the reducer is configured to easily adjust a distance from the side wall in the vertical direction as well as in the horizontal direction, a connection work between the reducer and the sprinkler head for the side wall construction connected to the reducer can be conveniently performed, and the intensity of the reducer fixing structure can be reinforced. | 10-02-2008 |
