  • Publication number: 20160141100
    Abstract: There are provided a rare-earth permanent magnet and a manufacturing method thereof capable of preventing deterioration of magnet properties. In the method, magnet material is milled into magnet powder. Next, a mixture is prepared by mixing the magnet powder and a binder made of long-chain hydrocarbon and/or of a polymer or a copolymer consisting of monomers having no oxygen atoms. Next, the mixture is formed into a sheet-like shape so as to obtain a green sheet. After that, the green sheet is held for a predetermined length of time at binder decomposition temperature in a non-oxidizing atmosphere so as to remove the binder by causing depolymerization reaction or the like to the binder, which turns into monomer. The green sheet from which the binder has been removed is sintered by raising temperature up to sintering temperature. Thereby a permanent magnet 1 is obtained.

  • Patent number: 9075234
    Abstract: A plurality of movable units is arranged in a matrix. First and second electrodes are used in common in the movable units arranged in a column. A plurality of third electrodes, which commonly connects tabular members of the movable units arranged in a row, is formed for each row. The drive circuit selects, in order and one by one, the third electrodes. Subsequently, the drive circuit swings the tabular member by applying a bias voltage to the selected third electrode and applying an approach voltage or a separating voltage to a plurality of the first electrodes and second electrodes. During a predetermined period of maintaining a swinging posture, the voltage applied to the third electrodes is maintained as the bias voltage. The tabular member is returned to a non-swinging state by changing the voltage applied to the third electrodes to a reset voltage after the lapse of the predetermined period.
