Title: Cooling granulation method and apparatus using short cylindrical container for particles with large particle size
Inventor: OKAWARA MASAAKI
IPC: B01J2/02
Filed: 1985-04-25
Abstract: PURPOSE:To efficiently classify particles with a large particle size, by providing a rotary disc shaped atomizer to the upper surface of a short cylindrical container having an inclined bottom surface and cooling and solidifying liquid particles discharged from said atomizer by cooling air flowing while revolving in the tangential direction of the peripheral wall of said atomizer. CONSTITUTION:A stock material is finely pulverized by the centrifugal force of an atomizer 2 to be scattered as stock material particles. Cooling air C is introduced into a container 1 from the tangential direction and flowed toward the center in a vortex form. Therefore, the stock material particles are countercurrently collided or contacted with the cooling air C and particles G with a large particle size traverse the air stream to be guided to the peripheral wall and are taken out from a large particle take-out part 6. Particles (g) with a small particle size are fallen in the vicinity of the central part and discharged from the small particle and exhaust air introducing port 7 provided to the central part of the inclined bottom surface of the container 1 along with cooling air. Further, particles floating on the inclined bottom surface are classified by the relative difference between the centrifugal force of particles accompanied by cooling air and the drag of the cooling air C flowing while revolving and the classified ones are respectively discharged in the same way.

Title: Pll speed control method for motor
Inventor: HORIE HIDEO
IPC: H02P29/00
Filed: 1991-03-27
Abstract: PURPOSE:To suppress speed fluctuation when a position error detector has a digital error by performing low frequency integration and lowering the positional gain in a bandwidth at a lower frequency than a speed control bandwidth. CONSTITUTION:A position target value is delivered from a target position setter to a position error detector 3 in an error detector 2 while a speed target value is delivered from a speed setter to a speed error detector 4. Positional error and speed error are then detected through comparison with a motor pulse PL fed back from a position pulse oscillator for a motor 5. A positional error output VP1 is then integrated at low frequency band in reference to a voltage reference Vr by means of a low frequency integrating circuit 6 and added through an adder circuit 7 to a speed error output VF. Output from the adder circuit 7 is fed to a power amplifier 8 thence applied onto the motor 5 thus driving the motor 5. This method realizes suppression of speed fluctuation when a positional error detector 3 has a digital error.

The furnace is furnished with a group 6' of the inlets of assistant fuel, air, water, etc. at the intermediate part and an air feeding port 15 at the bottom 31. Air is introduced upward from the port 15 to form a gyrating air stream. The exothermic partial oxidative combustion (high temperature) is induced in the gyrating upward gas stream at the center of the furnace, and the endothermic thermal decomposition of the fuel (low temperature) is induced in the downward gyrating gas stream near the wall of the furnace. The thermal decomposition zone is heated by the heat radiated from the center of the furnace to accelerate the water gas reaction of the system. The ash is separated by the centrifugal force caused by the gyrating motion and gravity and recovered and discharged from the bottom by the action of air elutriation. The produced water gas is discharged from the outlet port 5 at the upper part of the furnace.
