Title: Method of treatment waste water by way of photo- oxidation
Inventor: OOBA SHINJI
IPC: C02F1/72
Filed: 1977-12-19
Abstract: PURPOSE: To provide a method of treating waste water by way of photo-oxidation, which is capable of reducing COD and chromaticity of waste water at a low running cost, with combined use of a small amount of ozone and chloric oxidizing agent and ultraviolet rays.  
     CONSTITUTION: Chromaticity and COD of waste water is reduced efficiently by adding a small amount of ozone and a small amount of chloric oxidizing agent such as chlorine, sodium hypochlorite, bleaching powder, etc. into the waste water and radiating ultraviolet rays (having a wavelength of 2500 A) to the same. According to the method of this invention, amount of chloric oxidizing agent to be used can be reduced to about 1/7W1/10, as compared with the conventional methods in which chloric oxidizing agent and ultraviolet rays are used commonly, and its reaction rate and capacity of treatment can be both increased with addition of a small amount of ozone. Further, consumption of electric power can be saved since amount of ozone to be added can be small as compared with the similar conventional method in which ozone and ultraviolet rays are used commonly.

Title: Frame reception system in facsimile device
Inventor: YOSHIKAWA MASAYA
IPC: H04N1/32
Filed: 1981-09-29
Abstract: PURPOSE:To prevent mis-transmission, by neglecting a frame as a half-way reception when a carrier-on is detected at the start of reception and receiving a signal after the detection of carrier-off as effective signal, in a frame receptions system for a facsimile. CONSTITUTION:When a frame reception start signal is set on, an FF3 receives a J input and a clock signal CLK and is set or reset. When an MODEM 1 receives a transmission signal and a carrier detection signal CD is set on, a ''0'' signal is given to the J input of the FF3 to keep the reset state and a Q output remains ''0'' and an AND gate 2 is set off. When the carrier detection signal CD of the MODEM 1 is set off at no-signal, ''1'' level is inputted to the FF3 to set the FF3, the AND gate 2 is opened and a gate 5 is closed and remains set. In receiving a transmission signal in this state, the reception data is picked up from an AND gate 2 as an effective frame signal.
