Title: Snow forming machine
Inventor: TAKANO YOSHIKAZU
IPC: F25C5/14
Filed: 1988-02-09
Abstract: PURPOSE:To permit the forming of snow having a predetermined density and harden the surface of the formed snow, by a method wherein the periphery of a formed snow discharging straight tube is surrounded by a vessel and the vessel is provided with a heating fluid introducing means therein. CONSTITUTION:A snow forming tube 2 consists of a tapered tube 21 and a straight tube 22. The periphery of the straight tube 22 is surrounded by a vessel 221 and heating fluid is introduced into the vessel 221. Snow is thrown into a hopper 1 and is conveyed into the forming tube 2 by the rotation of a screw 3. The density of the snow, conveyed by the screw 3, is increased by the tapered tube 21 and a tapered section 31, thereafter, the snow is delivered to the straight tube 22. The snow, whose density is increased, is filled into the straight tube 22, thereafter, is pushed out of the straight tube 22 by the propelling force of the screw 3. The vessel 221 is attached to the straight tube 22 and fluid is heated by an electric heater 22 to melt the part of the snow, in contact with the inner surface of the straight tube 22, whereby moisture is permeated into the surface of the produced snow. The surface of the produced snow, discharged out of the straight tube 22 and formed so as to have a cylindrical configuration, is iced by atmosphere and the latent heat of itself whereby the density of the formed snow may be regulated so as to be the degree of 0.6-0.7 by the synergistic effect of the reduction of the diameter thereof and heating.

Title: Focus composite orientation disclike magnet and magnetic field orientation molding machine
Inventor: NAKATSUKA SATORU
IPC: H02K15/03
Filed: 1991-01-31
Abstract: PURPOSE:To eliminate futile magnetic flux of a disclike magnet, to increase a sensitivity of a signal generating magnet and to further reduce the number of manufacturing steps by integral molding by controlling orienting direction of magnetic powder in a magnet material. CONSTITUTION:Orienting direction of magnetic powder of a magnet material charged in a cavity is aligned with the direction of the line of magnetic force. That is, it is focused in the magnet to a central annular region of an operating surface side track, and the magnetic flux after magnetizing is contracted to a doughnut state. As a result, a torque generating disclike magnet 101 has almost no futile magnetic flux, and all magnetic fluxes are focused to a substantially operating surface to be effectively used, and hence a higher surface magnetic field is obtained. The magnetic flux of a signal generating ring magnet 102 of the outer periphery is effectively focused to the central region of the outer periphery, and hence its receiving sensitivity can be improved.
