Title: Treatment method of exhaust gas containing dust with high electric resistance
Inventor: HARIMA MIKIO
IPC: B03C3/013
Filed: 1979-09-03
Abstract: PURPOSE:To reduce the electric resistance of dusts and enhance the dust collecting efficiency by converting SO2 obtained from a desulfurising apparatus to SO3 and introducing said SO3 into an exhaust gas containing dusts with high electric resistance at an inlet side of an electric dust collector. CONSTITUTION:An exhaust combustion gas 1 from a boiler A is introduced into a denitrification apparatus B to treat nitrogen oxides therein. Subsequently, said gas is introduced into an air preheater C to heat to about 250 deg.C or less and introduced into an electric dust collector D, but, prior to introduction, a SO3 gas is introduced carefully so as to be uniformly diffused. The dusts with electric resistance lowered by the introduction of SO3 is collected efficiently by the electric dust collector D and the exhaust gas issued from the electric dust collector is utilized in a gas/gas heater E to raise the temp. of an exhaust gas generated from an absorbing tower F and the temp. lowered exhaust gas is entered into an absorbing tower F. In said absorbing tower F, a SOx (mainly SO3) component in the exhaust gas is removed by an exhaust smoke desulfurizing method.

IPC: B41J2/39
Filed: 1978-09-14
Abstract: PURPOSE: To prepare patterns that the concentration of pictures is high and contrasts are striking, by mounting a vibration means for slightly vibrating a multi-head portion and a portion material surface to be recorded in parallel.  
     CONSTITUTION: When signals in some freequency such as signals in periods shorter than time that a multi-head portion 5 and recording paper 8 contact are manufactured by means of an oscillator 1, and the signals are sufficiently amplified by means of a power amplifier 2 and applied to a trembler 3, the multi-head portion 5 fastened to the trembler 3 slightly vibrates in the direction that each head element forming the portion 5 is in a row. When the head elements are conduction heat generated under this condition and contacted with the recording paper, the recording paper heat-sensing color forms. Areas that form colors laterally spread in value wider than the areas of the head elements because the multi-head portion 5 minutely vibrates even during the contact, thus filling clearances between these picture elements and neighboring picture elements, then effectively improving sense opposing cocentration.

Title: Molten metal holding furnace
Inventor: KAMODA ISEO
IPC: B22D17/30
Filed: 1993-05-14
Abstract: PURPOSE:To make transfer of molten metal easy by arranging a tubular furnace main body, a trough shape box body equipped with a metering/pouring valve device, a movable weir freely ascendable/descendable placed at these boundary, a pressure enclosing tubular body inserted/held in the furnace main body and a compressed air inlet therein. CONSTITUTION:A high temp. molten metal supplied to a furnace main body 1 is pressurized by the compressed air injected from a compressed air inlet 3a of a pressure enclosing tubular body 3 so as to change a liquid level and go over a movable weir 4 from an opening of the lower end, transferring to a trough shape box body 2. When a liquid level in the trough shape box body 2 becomes higher than the upper end of the movable weir, compressed air is exhausted from the pressure enclosing tubular body 3, the molten metal in the trough shape box body 2 leaves a liquid level up to the upper end of the movable weir and returns to the furnace main body, freely flowing down. The molten metal having a volume of the specified quantity adjusted by a height of the movable weir is supplied to the trough shape box body 2. By this method, moving/tilting of a holding furnace is not required for transferring molten metal, having great energy saving. Also, the molten metal is shut off from outside, having lower generation of so as to prevent quality from deterioration.
