A heater system for a pipe for controlling a temperature of a heater installed to surround a pipe and performing a heating or insulation function.

Heater system for pipe

A heater for a pipe, includes a heater body part having a longitudinal cutting line formed in the entire thickness section to form a pair of longitudinal cutting planes in the entire length section, a heating wire installed in the heater body part, and a restraint operating part installed at the heater body part and restraining the pair of longitudinal cutting planes not to be spaced apart from each other. Each of the longitudinal cutting planes includes: a longitudinal outer cutting area disposed in a thickness direction from an outer surface of the heater body part, a longitudinal intermediate cutting area extending from the longitudinal outer cutting area in a circumferential direction of the heater body part, and a longitudinal inner cutting area extending from the longitudinal intermediate cutting area to reach the inner surface of the heater body part in the thickness direction of the heater body part.

Disclosed herein is an identifier based communication system including: a common communication path; a center station having a center station communication module and a center station controller connected to the center station communication module and connected to the common communication path through the center station communication module; and a plurality of distribution stations each including a distribution station communication module connected to the common communication path, a distribution station controller connected to the distribution station communication module, and a distribution station memory connected to the distribution station controller and storing a determined identifier value of the distribution station, wherein the center station controller transmits an identifier setting mode command including a center transmission preliminary identifier value to the distribution stations following an identifier setting request input from the outside; each of the distribution stations includes a distribution station display displaying information on the identifier value and an identifier selection key operated to select the preliminary identifier value displayed on the distribution station display as the determined identifier value of the distribution station; and wherein in a state where either a next preliminary identifier value of the setting mode or the center transmission preliminary identifier value is displayed on a corresponding distribution station display of each distribution, when a corresponding identifier selection key of each distribution station is operated to be on, the distribution station controller stores the preliminary identifier value displayed on the corresponding distribution station display in a corresponding distribution station memory of the distribution station as a determined identifier value of the setting mode of the distribution station, the distribution station controller displays the corresponding determined identifier of the setting mode on the corresponding distribution station display in a form different from the preliminary identifier value of the setting mode, the distribution station controller stores the corresponding determined identifier of the setting mode in the corresponding distribution station memory, and then transmits to other distribution station, a next preliminary identifier value of the setting mode, which is a value increased by the number N (positive integer) from the corresponding determined identifier value of the setting mode, the distribution station controller displays the center transmission preliminary identifier value received from the center station on the corresponding distribution station display after receiving the identifier setting mode command from the center station and until the distribution station controller receives the next preliminary identifier value of the setting mode from the other distribution station, and the distribution station controller sequentially displays the next preliminary identifier value of the setting mode received from the other distribution station on the corresponding distribution station display before the corresponding determined identifier of the setting mode is stored in the corresponding distribution station memory. In this manner, the identifier (ID) based communication system in the disclosure allows the user to easily select the determined identifier value of the distribution station as needed, has a simple configuration of the common communication path, and allows the user to easily visually confirm the determined identifier value of each distribution station.

Identifier (ID) based communication system

A utility box which includes a concave-shaped box having a box opening on a top end of the box and a cover plate installed on the box to cover the box opening. The box has a box body, a box shoulder, and a box opening formed on the top end of the box. A pair of lower horizontal guide surfaces are disposed parallel to each other. The box shoulder has a shoulder body and a pair of upper horizontal guide surfaces. A cover plate is formed to have a cover plate wide width portion and is installed in such a manner that the cover plate wide width portion is supported on the lower horizontal guide surfaces. A cover plate opening/closing support controls the cover plate. The box body has improved inner space utilization and a region of its cover plate has a simple structure.

Utility box

Provided are a carrier head and a carrier head unit for sucking and securely supporting a substrate during a chemical mechanical polishing process. The carrier head using sucking force to fix a substrate includes a head main body that includes a receiving space in a central portion thereof, the receiving space being opened downward to receive the substrate, a housing part in an edge thereof to surround a side portion of the receiving space, a main passage passing through the head main body to communicate with the receiving space, and a plurality of connecting holes vertically passing through the housing part to communicate with the main passage, a retaining ring coupled to a bottom surface of the housing part of the head main body to close lower portions of the connecting holes, and a cover coupled to a top surface of the head main body to close upper portions of the connecting holes.
