  • Publication number: 20200133025
    Abstract: Eyewear having: a frame; an optical module held by the frame and changing optical properties by electric control; a sensing unit that obtains information pertaining to a usage environment; and a control unit that, on the basis of the information obtained by the sensing unit, changes the optical properties of the optical module. The control unit switches between a mode in which optical properties of can be changed and a mode in which optical properties cannot be changed, on the basis of the information obtained by the sensing unit, and changes the optical properties of the optical module when in the mode in which optical properties can be changed. As a result, eyewear is provided that can switch between modes that change or do not change optical properties, in accordance with the usage environment.

  • Patent number: 4933654
    Abstract: A polarized electromagnetic relay having a pair of first and second pole members which are magnetized to opposite polarity by a permanent magnet coupled thereto and which define therebetween a magnetic gap into which the other end of the armature extends. The first pole member and the armature are magnetically coupled to the base so as to cause a magnet flux of the permanent magnet to circulate through the second pole member, the armature, the base, and the first pole member for attracting the armature to the second pole member. Upon energization of the coil, a resulting coil flux circulates through the armature, the base, and the first pole member in opposing direction to the magnet flux for attracting the armature to the first pole member. A cover and base of magnetic material is included to fit over the base and be magnetically coupled thereto.

  • Patent number: 4568207
    Abstract: An improved magnetic actuator mechanism suitable for dot printing mechanisms for use in a wire matrix dot printer. The present magnetic actuator mechanism comprises an armature movable between a reset position and an actuated position, a permanent magnet for attracting the armature toward the reset position, and an electromagnet which, when energized, generates in the armature a magnetic flux opposite to and larger than the magnetic flux generated therein by the permanent magnet. The armature is thus moved to the actuated position by the turn of the magnetization direction in the armature when the electromagnet is energized.
