is an elastic member, fastened to a fastening flange 67 of the cylinder 51 for fastening the refrigerator 30. In addition, an "O" ring 71 which is an airtightening sealing member is disposed between the fastening flange 67 and the flange 68.
When the flange 68 is fixed to the fastening flange 67 by making use of the bolt 69, the flange 68 slides while maintaining the airtightness thanks to the "O" ring 71. The fastening force of the bolt 69 plastically deforms the indium wire 66 so that the thermal connection is established between the heat conductor 64 adjacent to the cylinder 51 for fastening the refrigerator 30 and the heat conductor 65 adjacent to the refrigerator 30.
Excessive fastening force of the bolt 69 and the displacements ofmisdemeanor for anyone else to engage in garbage hauling services. Teresa and Matt Plummer ("Plummer") operated a competing sanitation business and the City enforced the ordinance by citing and arresting Plummer's employee for collecting and hauling garbage. The ordinance was later repealed. Plummer sued the City, raising antitrust claims and a claim for tortious interference with their business.
