Title: Apparatus for firing powdered material such as alumina
Inventor: SUZUKI TAKESHI
IPC: B01J6/00
Filed: 1978-02-20
Abstract: PURPOSE:Air from the cooler and exhaust gas from the firing furnace are adjusted to a selected temperature and introduced into the dryer so that the hot gas to the electric dust collector can be maintained over the dew point and that thermal consumption is reduced. CONSTITUTION:Raw Al2O3 cake is charged into the dryer 22 and is dried while being transferred to the cyclone 25. The dried material is dehydrated while passing through the duct 26, the cyclone 27, the auxiliary furnace 28 and to the cyclone 30. The material is, then, fired in the firing furnace 31, cooled in the cooler 33, 36 and discharged as product. When the burner 44 of the auxiliary furnace 28 is in complate combustion, the hot gas in the duct 29 is about 600 deg.C and the hot gas in the duct 45 is about 300 to 350 deg.C, which is not enough to dry water deposited on the cake. To raise this temperature, high temperature air extracted through the duct 42 from the second cooler 36 is partially introduced into the dryer 22 so that the exhausted air from the dryer 22 reaches about 450 deg.C. As a result, the hot air over the dew point is introduced into the electric duct collector 48.

Title: Ink jet
Inventor: YASUGATA KAZUHIRO
IPC: B41J2/015
Filed: 1988-01-29
Abstract: PURPOSE:To enhance energy efficiency, by injecting ink containing superconductive fine particles showing Meissner effect by magnetic force. CONSTITUTION:In an ink jet 2, a line of magnetic force is formed in a superconductive wire 7 constituting a superconductor coil 8 by the application of a DC voltage pulse to the superconductor coil 8 by a pulse generating circuit 14 and large magnetic force is formed along the center axis of the superconductor coil 8. Since ink 6 containing superconductive fine particles is received in an ink receiving part 4 where said large magnetic force is generated, large repulsive force acts on the ink in the direction of a nozzle 3 by Meissner effect. As mentioned above, since the ink containing the superconductive fine particles is allowed to repulse by magnetic force and the repulsive force is allowed to act as injection force, energy efficiency is well and, in spite of low electrical energy, the injection force of the ink can be extremely increased.

Title: Electric brake control method for electric car
Inventor: KINOSHITA SHIGENORI
IPC: H02P3/18
Filed: 1994-01-20
Abstract: PURPOSE:To lessen a share of braking power for a power absorber and to decrease the capacity by increasing motor current, raising the switching frequency of a semiconductor power converter, and increasing the losses of the motor and the converter, when a part or the whole of the braking power is absorbed. CONSTITUTION:At the the of the annulment of regenerative braking, control is so performed that required braking power may be generated in a motor 5 by making the output current of an inverter 4 a square-wave approximately, and enlarging its magnitude up to no allowable maximum value. Besides, switching frequency to semiconductor devices constituting the inverter 4 is also increased up to an allowable maximum value. As a result, a share of braking power for a power absorber such as a resistor 91 etc., decreases, since losses generated in the motor 5 and the inverter 4 increase. Consequently, it becomes possible to decrease the capacity of the power absorber such as a resistor etc., and to reduce the size and weight.
