A thermoplastic molding material contains between 10% and 35% by weight of an ethylene copolymer wax with hydrophilic groups, with a melting point between 75\xb0 C. The implantable medical device system includes a sensor that outputs a blood flow rate signal representing a rate of blood flow through a coronary sinus of a patient’s heart. A body-supporting harness assembly, located atop the inclined surface, is attached to the base and is movable between a first body supporting position away from the general horizontal surface and a second position toward the generally horizontal surface. The high-frequency switch has PIN diodes as switching devices, and performs switching between a global system for mobile communications transmission signal and a global system for mobile communications reception signal. This method makes it possible to fabricate a semiconductor crystal substrate in which the concentration of interstitial carbon atoms is satisfactorily reduced, thus resulting in excellent electrical properties when the substrate is applied to a semiconductor device. This low pressure combustion synthesis technique may be used for production of Co-based and other metal-based alloys, which cover the entire range of orthopaedic implants, including total hip and knee replacements, as well as hone screws, plates, and wires.
