Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
128 words
In a vehicle having an electric device sensitive to an electric noise wave and having an electric air cleaner for cleaning air in a passenger compartment, said cleaner being positioned close to the electrically sensitive device and comprising an electrostatic precipitator for removing fine dust particles suspended in the air, said precipitator including electrically insulated first and second groups of electrodes between which a high electric potential is applied: said cleaner further comprising an ultraviolet lamp for sterilizing the air: a cover member constructed of an electrically insulating material and having an opening, said cover member being arranged to cover said lamp with the opening facing away from said electrically sensitive device; and an electrically grounded, vacuum evaporated metal film lined to the inner surface of said cover.
Claim 2
Dependent Claim
128 words
