Abstract: A process for treating colored liquid comprises a step of contacting a colored liquid and functional water generated by electrolysis of a water solution of an electrolyte under light irradiation, to decolorize efficiently and stably to a low chromaticity.

Abstract: A method is provided for culturing a microorganism in a culture medium containing a carbon source and an electrolyzed water containing not more than 0.4 ppm chlorine produced during electrolyzing water containing an electrolyte in an electrolytic cell. The culture medium may also contain a carbon source and an acidic water having a pH value of 1-4 and a redox potential from 800 mV to 1500 mV. The acidic water is obtained by electrolysis of water in an electrolytic cell. Further, the culture medium may contain a carbon source and an alkaline water having a pH value of 10-13 and a redox potential from −1000 mV to 800 mV. The alkaline water is obtained by electrolysis of water in an electrolytic cell. The redox potential for the alkaline water is determined by the use of a platinum electrode as a working electrode and a silver-silver chloride electrode as a reference electrode. The microorganism may be selected from Escherichia coli, strain J1, strain JM2N, or an artificial recombinant.

Abstract: A method for producing L-lysine by fermentation, which comprises, culturing aerobically in a culture medium a mutant of the genus Brevibacterium or Corynebacterium which is resistant to ethylene glycol and capable of producing L-lysine, and recovering the L-lysine which accumulates in the culture medium.

Abstract: The present invention relates to a self-timer device for a motion picture camera which presents a second motor switch connected in series with the first motor switch to be closed by means of the release means at the time of the camera release, the first timer means including a governer mechanism for actually starting photographing, closing the second motor switch after the elapse of a certain determined time from the automatic photographing setting and the second timer means for stopping the camera release after the elapse of a certain determined time from the actual starting of photographing, so as to open the first motor switch and terminate the photographing. In this manner the first timer means is driven by means of a spring means as a driving source while the second timer means is driven by means of the camera driving motor as driving source and controls the timing of the start and stop of the photographing at the time of the automatic photographing.

Abstract: A lubrication unit is provided for lubricating drive and driven members used in a film apparatus which continuously feeds a film in a small size motion picture camera, a motion picture projector, a still camera incorporating a motor drive or the like. The unit includes lubrication means for lubricating engaging parts of a drive member that is rotatively driven and a driven member which is held in engagement with the drive member when the drive member is driven at a high speed. The lubrication means includes a lubricant storage in either a drive member or driven member, the lubricant storage communicating with the engaging surfaces of the drive and driven members to supply a controlled amount of lubricant thereto under the influence of the centrifugal force that is developed upon rotation of either drive or driven member.
