  • Device for minimizing earthquake shocks to a small building
    Patent number: 6085474
    Abstract: An inexpensive device for minimizing earthquake shocks to a small building. A foundation of the building is divided into an upper foundation and a lower foundation. Grains of sand are rollably disposed between the upper foundation and the lower foundation. The grains of sand support the weight of the building including the upper foundation. The building is not moved in a horizontal direction by a small force of wind, etc.

  • Gas cylinder
    Patent number: 5267852
    Abstract: A nonwoven fabric (31) having an annular shape in the horizontal cross-sectional view is put inside of a pressure-resistant wall (11) of a gas cylinder (2) adapted to contain liquefied petroleum gas (19). An outer surface (34) of the nonwoven fabric (31) is kept in contact with an upper portion of an inner surface (20) of the pressure-resistant wall (11). A lower section (33) of the nonwoven fabric (31) is adapted to suck up the liquefied petroleum gas (19) in its liquid phase portion (25) owing to capillary action, so that the sucked up liquefied gas can be brought into contact with the upper portion of the inner surface (20) of the pressure-resistant wall (11).

  • Linear stepping motor
    Patent number: 4714849
    Abstract: A linear stepping motor, including a pair of exciting iron cores having a plurality of field legs which form a plurality of denticles with a common pitch .tau.; wherein, when P is the number of poles and n is the number of phases of the linear stepping motor, the spacing of the field legs is (N+(m/n)). .tau. (where N is an integer, m is an integer, and m is an integer, and m<n); and the denticles on the pair of exciting iron cores are shifted in phase by no more than (L/P)..tau. (where L is an integer, L<P, and 2L.noteq.P).

  • Method for effecting hydrogen sorption and dissociation on an adsorbent metal
    Patent number: 4490348
    Abstract: A method and apparatus for effecting hydrogen sorption and dissociation on an adsorbent metal at an elevated temperature, wherein the method is carried out in an apparatus including a vessel for containing an adsorbent metal, the vessel including a hydrogen intake path and a hydrogen discharge path, a pair of electrodes located at opposite ends of the vessel such that the vessel is insulated to the electrodes, and a source of power for supplying electric current to the electrodes, so as to effect electric current between the electrodes through the adsorbent metal.
