Abstract: PURPOSE:To effectively and inexpensively make the gases to be treated pollution-free by introducing the gases to be treated into a gas treating section from a gas inlet so as to pass the gases near high-frequency creeping discharge generating surfaces and treating the above-mentioned gases by a plasma chemical effect. CONSTITUTION:The waste combustion gases contg. SO2 and NO are passed from a boiler through an upstream side duct 4 and after gaseous ammonia is injected from an injecting section 7 into these gases, the gases are passed through a screen 8 and are introduced at a uniform gas flow rate distribution into the inside 27 of the gas treating section 1 from a gas inlet 2 thereof. The SO2 is oxidized to SO3 and the NO to NO2 by the effect of the ample radicals, chemically active species, etc., formed by the plasma chemical effect during the flow through spacings 28, 29 of the planar high-frequency creeping discharge element groups 9, 10. Further, both thereof react with the ammonia and form the solid aerosol particles of the double salt of ammonium sulfate and nitrate.

Abstract: PURPOSE:To improve quality of a recording image by a method wherein the thermal transfer recorder is so constructed that a number of electrifying pulses determining energy to be applied to a heating element is determined according to a drop quantity of voltage at a thermal head. CONSTITUTION:An output signal from a CPU 13 is outputted from the CPU 13 to a correcting means 14 according to an accumulated result obtained by having accumulated a gradation level signal from an input terminal 11 in a line. Then, a ROM is accessed by taking a one line delayed gradation level signal from a line buffer 12 and a correction number being an output of the CPU 13 as an address. When the correction number according to a drop quantity of voltage is, for instance, '1' even though the gradation level signal from the line buffer 12 is '5', the gradation level signal after correction becomes '2'. Then, the gradation level signal after correction is inputted to a pulse number generating means 15 and is supplied to a thermal head 16 as a number of electrification pulses. It becomes possible thereby that a half tone image quality of a high grade is obtained by removing irregularity in density.

IPC: G03G13/08
Filed: 1978-06-12
Abstract: PURPOSE:To enable accurate toner concentration control, by limiting the wavelength region of the light to be received reflected from a developer to steepen change of reflection light intensity against toner concentration. CONSTITUTION:Developer d is irradiated with light from light emitting station 3b through transparent plate 3a arranged in the bottom of developer tank 21, and the reflected light is received with photodetector 3c.

Title: Communication controller
Inventor: OOTA HIDEAKI
IPC: G06F13/00
Filed: 1981-05-09
Abstract: PURPOSE:To prevent the deterioration of the service time of a CPU to the process when the speed of communication is increased, by storing previously the data to be transmitted or the redeived data in a buffer memory and then transmitting or reading successively these data. CONSTITUTION:In the case of transmission of the data, a CPU sets the transmitting data to a buffer memory 7 and then transmits the transmission start signal. Receiving this signal, an asynchronous receiver/transmitter ART9 transmits the data set at the memory 7 to the remote side through a terminal TRO. Then the circuit is switched to a reception mode when the transmission end signal is transmitted. Thus the ART9 receives the signal from the remote side through a terminal Ri to successively store the signal in the memory 7. When the reception end signal is received, the data of the memory 7 is transferred to the CPU through a gate circuit 8 and a data bus 4 and under the control of the CPU.
