摘要： Greatly improved heat and light resistance is imparted to polyvinylidene chloride resins by incorporating therein a specific chlorinated ethylene-vinyl ester copolymer to minimize the quantities in said resins of conventional additives, of which migration is undesirable from a viewpoint of food hygiene. The resulting polyvinylidene chloride resin compositions also have excellent gas barrier properties and high transparency.

摘要： An electromagnetic field strength reducing device includes a high-frequency wave eliminator that eliminates a high frequency component from an electrical signal input from a signal source. An electrical signal line is disposed between the high-frequency wave eliminator and the electrical member so as to convey the electrical signal with the high frequency component eliminated to an electrical member. The device also includes a resonant-frequency regulator connected between the electrical signal line and ground to cause the electrical signal line to be resonant at a frequency used for radio communication. The electromagnetic field strength reducing device may be employed in a portable electronic device with a HAC standard radio frequency communication compliance requirement, and use a corresponding method to eliminate the high frequency component.
