IPC: F24F1/00
Filed: 1979-03-30
Abstract: PURPOSE: To clarify room air by a method wherein an oxygen doner mainly consisting of peroxide(s) is added to water in a water tank of a heating type humidifier, the water is heated, and oxygen generated through decomposition of the peroxide(s) in the oxygen doner is entrained in steam for clarifying room air.  
     CONSTITUTION: At least one compound selected from the group consisting of urea peroxide, percarbonates, perborates, and hydrogen peroxide is added to water in a water tank of a heating type humidifier, and the water is heated. Oxygen generated during heating is fed into a room together withs steam, to clarily room air. By this, oxygen can be replenished to keep room air clean even when the humidifier is used in a room being shut off.

IPC: H01B7/28
Filed: 1993-02-25
Abstract: PURPOSE:To provide a cable having high water tree resistance. CONSTITUTION:This water tree resistant cable has an insulation composition made of one or both of 0.1 to 1.0 pts.wt. of a phenol age resistor and a phosphor age resistor added to 100 pts.wt. of base polymer mainly composed of polyethylene having extra low density between 0.89 and 0.91g/cm<3> laid as an insulator on a conductor.
