IPC: B09B3/00
Filed: 1977-11-17
Abstract: PURPOSE: A thermal decomposition furnace of simple structure designed to decompose dusts efficiently, continuously, rapidly, and securely, wherein the dusts are dried by hot gas, and dispersed uniformaly in the furnace after blending well with charged hot sands.  
     CONSTITUTION: Dusts in the dust storage tank 18. are fed through the chute 5 and the changing hole 4 into the furnace 1 by the screw conveyor, 6 and sent gradually to the center of the furnace 1 by the rotary dryer blades 7. The dusts are dried while being in contact with the hot gas rising toward the exhaust 3 thorugh the gaps of the rotary dryer blades 7. The dusts thus dried are mixed with hot sands introduced from the chute 9 in the guide plate 8, dropped on the rotating dispersion element 16 and blended uniformly with the sands throughout the furnace 1. The dusts are thermally decomposed by the heat of the hot sands while staying at the bottom of the furnace. Combustible gases produced are removed from the exhaust 3: oils formed, from the outlet 17.

Title: Ink jet recording apparatus and removal of foreign matter of ink jet head

IPC: B41J2/175
Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To well remove the scorched deposit or precipitate on a heater by the generation of constant cavitation by providing a drive condition setting means determining the drive condition of a non-communication drive means on the basis of the data obtained by at least a head characteristic detection means. SOLUTION: When the pulse width of an emitting signal is large, a bubble insufficient to emit ink is generated in certain pulse width (the start of an A-region) and, when the pulse width is made further large, ink is emitted in such a state that the bubble does not communicate with the atmosphere. When the pulse width is made further large, ink is emitted in such a state that the bubble communicates with the atmosphere (the bondary of regions A, B). The range of the pulse width capable of generating an air bubble generating effective cavitation within the A-range is different according to the individual difference of the characteristic value of an ink jet head or a recording apparatus and the proper range generating this cavitation is detected at every ink jet head at a point of time of the treatment of scorching on a heater.
