Title: Method of controlling melting processing furnace
Inventor: FURUKAWA TOSHIHARU
IPC: F23G5/00
Filed: 1985-11-11
Abstract: PURPOSE:To promote a saving of electrical power caused by a reduction in a thermal radiation and at the same time to prevent dust from being diffused or dispersed at a melting surface by a method wherein a feeding electrical power is controlled in response to a level of mattes to be processed and accumulated in a furnace and a sensed temperature at a top part of the furnace, or to their sensed values in such a manner as the temperature at the top part of the furnace may become less than a desired value. CONSTITUTION:Level meters 8A and 8B will detect a level of a waste material 5 under a variation of torque which is attained by ascent or descent of a weight 8b fixed to a wire 8a with a winding electric motor 8c. Thermometers 10A and 10B will output a sensing signal for causing the weight 8b to be retracted to the top part 1b of the furnace when a temperature more than 800 deg.C is sensed. Output signals from the level meters 8A and 8B, and the thermometers 10A and 10B are fed to a control device 20 and an electric power for main electrodes 4A, 4B and 4C is controlled stepwise through a power supply 30. Therefore, even if the waste material shows a better aeration characteristic, the temperature at the top part of the furnace can positively be restricted to a value less tan the predetermined value. With this arrangement, a thermal radiation at the melting surface can be reduced and a saving of the electric power can be attained and at the same time a distribution of the dust from the melting surface can be reduced.

Title: Electrically-driven curtain driving gear
Inventor: KOSHIN HIROAKI
IPC: A47H5/02
Filed: 1992-09-25
Abstract: PURPOSE:To improve the curtain driving gear as a speed detector by a method wherein, even when an output current is large, the linearity of a B-H curve can be maintained without making the shape of a current transformer large and a speed can be detected surely. CONSTITUTION:A gap is formed in one part of a core 5 for a current transformer 4, and a permanent magnet 9 is inserted into, and fixed to, the gap. The polar direction of the permanent magnet 9 is set in such a way that its magnetic flux becomes a direction opposite to the direction of a magnetic flux generated in the core 5 by a primary winding 6. By this setting, in the B-H characteristic of the core 5 provided with the permanent magnet 9, its linearity of the change width of a flux density B can be maintained so as to be proportional to the change width of the strength of a magnetic field even when the strength of the magnetic field is changed by a definite width when an output current is large. Consequently, irrespective of whether the output current on the primary side of the current transformer 4 is large or not, the amplitude of the output of a secondary winding 7 is changed little, and the speed of a motor can be controlled surely by a control part.
