Abstract: According to one embodiment, a permanent-magnet type electric rotating machine has a stator, a magnetizing coil, a rotor and a case. The stator has an armature coil configured to form a magnetic circuit for driving. The magnetizing coil is configured to form a magnetic circuit for magnetizing. The rotor has a constant magnetized magnet, a rotor core and a variable magnetized magnet. The rotor core holds the constant magnetized magnet. The constant magnetized magnet is arranged closer to the magnetic circuit for driving than the variable magnetized magnet. The variable magnetized magnet is arranged closer to the magnetic circuit for magnetizing than the constant magnetized magnet.

Abstract: An intake port (2) is formed in a casing (1), a plurality of discharge ports (3) are formed in a side face of the casing (1) different from this intake port (2), or are arranged continuously along the entire circumferential surface of the side face of the casing 1. A series of vanes (5) of a centrifugal type blower (4) for feeding air flowing in from the intake port 2 to the discharge ports (3) are arranged around the intake port (2) within the casing (1) and a photocatalyst carrier (6) that carries photocatalyst is arranged at the outer periphery of the series of vanes (5) of this centrifugal type blower (4).

Abstract: An odor component in an air is deodorized by an ozone generating member in an ozone an ozone generating area formed in a path through which the air flows, the generated ozone is decomposed by an ozone decomposing member in an ozone decomposing area, and a carbon monoxide, generated in, for example, through incomplete combustion, a CO adsorbing area in the path is adsorbed and carried by a CO adsorbing member. The ozone decomposing area and the CO adsorbing area are formed in a common oxidizing reaction area in which the carbon monoxide is oxidized by using active oxygen generated through the ozone decomposing step in the oxidizing reaction area.

Abstract: A gas purifying system for purifying an object gas includes a gas flow line through which the object gas to be purified flows from an object gas generation mechanism, a discharge reaction device provided on a way of the gas flow line, a filter member disposed in the discharge reaction device having a structure capable of trapping particular matter contained in the object gas during a time when the object gas passes through the filter member; and a discharge generation device operatively connected to the discharge reaction device for causing electric field inside the discharge reaction device and generating discharge plasma therein.
