  • Magnetic display unit
    Patent number: 4750003
    Abstract: A magnetic display unit in which a magnetic panel encloses a colored liquid in which magnetic particles are dispersed. A recording head moves over the panel and has a plurality of electromagnets arranged with at least three electromagnets on each of parallel lines inclined to the direction of movement of the recording heads with all the electromagnets being arranged on equal pitch perpendicular to this movement direction. The electromagnets are selectively actuated as the recording head moves to write a dot pattern.

  • Aluminum nitride sintered body and process for producing the same
    Patent number: 4746637
    Abstract: Disclosed are an aluminum nitride sintered body comprising aluminum nitride, rare earth element-aluminum compounds and alkaline earth metal-aluminum compounds, and a process for producing an aluminum nitride sintered body, which comprises adding to aluminum nitride powder:(a) powder of at least one compound selected from the group consisting of rare earth element oxides, rare earth element fluorides and compounds capable of being converted into these oxides or fluorides by calcination, and(b) powder of at least one compound selected from the group consisting of alkaline earth metal oxides, alkali earth metal fluorides and compounds capable of being converted into these oxides or fluorides by calcination, in a total amount of 0.01 to 20 wt % as calculated on the weight of the oxides or the fluorides, and then molding and sintering the resultant mixture.
