To provide products such as a magnetic recording medium utilizing a hard magnetic material.
A hard magnetic magnetic anti-magnetic recording medium is constituted so that a hard magnetic material is formed into foil to form a tape. A magnetic recording medium applied by hard magnetic powder is constituted so that the hard magnetic material is made minute powder by a hot water melt atomizing method or the like and the powder is applied on a tape. A chemical hard magnetic powder application magnetic recording medium is constituted so that a hard magnetic alloy constitution element is made powder individually and chemically and they are mixed appropriately and made the hard magnetic material as a whole and applied on a tape or a sheet. The magnetic recording medium uses a carbon group element mix strong hard magnetic material. A magnet electrode type true fuel cell uses a magnet cathode absorbing hydrogen and a magnet anode. absorbing oxygen. A light weight high efficiency electric motor is constituted so that one collector ring is increased and power is supplied to respective electrodes and electrodes of a stator are made multi-pole. A wind force rotation fliers has a twist angle of 45 degrees. A wind force efficient air plane is constituted so that propulsion objects such as a propeller or the like are divided to left and right of a body, wings, or the like, and arranged outward.
