Title: Agent and method for controlling dioxin generation
Inventor: FUJIYOSHI NAOAKI
IPC: B01D53/70
Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To enhance both an effect to control the generation of dioxins and an effect to remove generated dioxins by adding to exhaust gas a controlling agent obtained by mixing carbonates or hydrogen carbonates of one or more elements selected from the group consisting of sodium, potassium, calcium and magnesium with activated carbon. SOLUTION: The dioxin generation controlling agent is prepared by mixing alkaline carbonates, namely carbonates or hydrogen carbonates of one or more elements selected from the group consisting of sodium, potassium, calcium and magnesium, with activated carbon. Alkali can be added and deposited because that the activated carbon restrains the catalytic action to generate dioxins. The one obtained by mixing sodium hydrogen carbonate with powdery activated carbon by a prescribed weight ratio is added by a prescribed ratio to the exhaust gas of the inlet flue of an electrostatic precipitator 4, for example, in the case of the exhaust gas from the incineration equipment for city refuse consisting of a stoker furnace 1, a waste heat boiler 2, a gas cooling chamber 3, the electrostatic precipitator 4 and a chimney 5.

IPC: G02F1/133
Filed: 1984-08-10
Abstract: PURPOSE:To obtain sufficiently orientation control force even if an applied pressure is small, by sticking base ends of many fibers which have formed many projections of an acute angle adjacently in the peripheral direction, to a supporting member which is driven so as to move to an oriented film. CONSTITUTION:Many projections 3 formed adjacently on the peripheral wall of a fiber 2 have a triangular section, the tip angle of the projection is <=60 deg., and it is projected sharply to the outside.

On the other hand, when current IL becomes small and becomes less than threshold value of the circuit 20, decision output of the circuit 20 becomes zero V and each switching circuit becomes 'on' state. Then, constant voltage circuits of circuits 7a, 7b become active state and non-active state respectively. Bias voltage of the circuit 7a is supplied to the Tr 5 and changed to equivalent DC characteristic E, and operation of a branch telephone set is secured to a small current value.

IPC: G04C10/04
Filed: 1986-07-18
Abstract: PURPOSE:To enable precise calibration with a simple construction, by dividing a test signal to generate two coherent signals, which are applied simultaneously to measure and calibrate the time interval between the signals. CONSTITUTION:A test pulse from a pulse generator 1 via a switch 17 of a calibrator 3 is divided into two coherent pulses with a 0 deg. power splitter 13 and a 180 deg. power splitter 15 separately. These two pulses are selected with a switch 19 and furthermore, the connection is changed over with a switch 21 to the channel A or B for starting or stopping of a counter 5. Then, the differences in the delay time between output slopes of amplifiers 9 and 11 in the channels A and B is measured with respect to applied signal slopes at each of the same and opposite slopes and by switching the applied slopes between the channels A and B. When these differences are averaged, a precise calibration value is obtained irrelevant to skew, through-rates and the like. Thus, the precise calibration of a time interval measuring counter can be performed with a simple construction that enables the use of a distorted pulse.

Abstract: PURPOSE:To record a two-color image well without color mixture, by charging frictionally a toner of the first color, which is mixed in a developing device for the second color, with a polarity different from that of the second latent image charge to prevent accumulation of the toner of the first color. CONSTITUTION:A positive-polarity latent image formed on a photosensitive drum 1 is developed in the first developing device 5 using a toner 4 of the first color having a positive polarity. The second positive-polarity latent image is formed on the drum 1 by exposure and is developed in the second developing device 8 using a toner 7 of the second color having a positive polarity. In this case, a part of the toner 4 on the drum 1 is peeled by a magnetic brush due to the device 8 and is mixed into the toner 7 of the device 8 and is charged frictionally by the carrier and the toner 7 of the device 8.
