Abstract: A dispersing and grinding device for dispersing or grinding particles in a particle-containing liquid with a shear force generated when the particle-containing liquid passes through a gap, the dispersing and grinding device including: a casing; a rotor, a stator, and an impeller; and drive means. The gap is defined between the stator and the rotor. When the rotor and the impeller are rotated by the drive means, the particle-containing liquid is allowed to flow into the casing through an inflow portion of the casing by a rotating force of the impeller, and passes through the gap to cause the particles in the particle-containing liquid to be dispersed or ground with a shear force generated when the particle-containing liquid passes through the gap.

Abstract: A dispersing device includes: a casing having a liquid inlet; a rotating body accommodated in the casing and pivotably attached to a rotating shaft from one end of the rotating body; a liquid channel having, on the other end of the rotating body, a passage through which the liquid from the liquid inlet passes, and, inside the rotating body, a segment extended radially around the rotating shaft toward an outer side perpendicular to the rotating shaft and from the other end of the rotating body toward the one end of the rotating body in a direction of the rotating shaft axis and in which a cross section shape perpendicular to the rotating shaft is annular; and one connecting hole in the rotating body connecting the liquid channel with the exterior of the rotating body downstream of the liquid channel.

Abstract: The media-circulation type pulverizer comprising: an agitating member disposed in a lower region of a pulverization chamber; an annular partition wall disposed to extend upwardly in the pulverization chamber; and a media guide member provided on a lower surface of the end plate of the agitating member, wherein the annular partition wall has a height set to be ? to ? of a height of the pulverization chamber, and the media guide member has a lower end which enters a space of the inner region of the pulverization chamber located inside the annular partition wall, and wherein a vertically-extending flow straightening blade is provided between said lower portion of the media guide member and an upper portion of the annular partition wall, and the media separation member is provided on the lower end of the lower portion of the media guide member.

Abstract: The media-circulation type pulverizer comprising: an agitating member disposed in a lower region of a pulverization chamber and having a rotary shaft substantially coaxial with a central axis of the pulverization chamber; an annular partition wall disposed to extend upwardly from a position surrounding an outer periphery of the agitating member or a position radially away from the outer periphery by a given distance, so as to radially divide an internal space of the pulverization chamber to form an inner region of a pulverization chamber and an annular outer region of a pulverization chamber; a media guide member provided on a central area of a lower surface of the end plate to extend downwardly and configured to turn a mixture of a raw material slurry and pulverizing media being moved upwardly through the outer region of the pulverization chamber by an action of the agitating member, to a downward flow so as to direct the mixture toward the inner region of the pulverization chamber; a media separation member

Abstract: The object of the present invention is to provide a medium agitation mill which is responsive to the standstill of the mill for preventing the pulverizing medium from invading the inside space of the longitudinal hollow space of the drive shaft of the impeller. In the medium agitation mill the medium separating impeller is arranged in the inside space of the agitating member, and the impeller has a plurality of vanes circumferentially arranged at intervals, and is driven by the hollow drive shaft, one end of which opens to the inside of the impeller to provide the raw material discharging port. The discharging port is provided with an on-off valve of a resilient material to open and close the discharging port.

Abstract: A facsimile interface device for a land-mobile telephone system includes a changeover circuit for connecting and disconnecting a facsimile device with a land-mobile telephone circuit, and a matching circuit for electrically matching the facsimile device to the telephone circuit. The interface device further includes a control circuit for determining based on the position of a mode select switch whether a signal received is for the telephone circuit or the facsimile device, and for controlling the changeover circuit accordingly.

Abstract: A method of synthesizing a musical sound in which a fundamental waveform signal is produced which has a zero crossing point within one cycle period thereof and the phase of the zero crossing point is modulated by a modulation signal to provide a musical tone with a complex waveshape.

Abstract: A sinusoidal waveform is approximated by alternately connecting downward opening parabolic curves and upwardly opening parabolic curves at their open ends. A variable input digital representation changing at a certain rate is subjected to a coordinate conversion and squaring operation to provide amplitude samples to constitute a quasi-sinusoidal waveform. All the operations are performed through logical circuits without using a read only memory.
