Title: Method and system for confirming transmittal
Inventor: OKAMOTO TATSUAKI
IPC: G09C1/00
Filed: 1994-08-03
Abstract: PURPOSE:To reduce the amount of calculation required for discriminating whether or not a party returning an acknowledge is a correct recipient by converting repetitively a communication text reaches from a destination sender by means of a unidirectional function offering one-to-one conversion at a fast processing speed. CONSTITUTION:A transmitter-receiver A100 sends secret information to a transmitter-receiver B200 as an electronic document. Upon the receipt of the document from the transmitter-receiver A100, the transmitter-receiver B200 returns an acknowledgement to the transmitter-receiver A100. The communication system is made up of a commit stage to send the secret information and a disclosure stage to disclose the secret information. Then whether or not the presence of inversion of the secret information with respect to any conversion is verified by using the conversion using the unidirectional function offering one-to-one conversion, and illegal data disclosure of the transmitter-receiver is detected by using the property that sole inversion is attained when the inversion is in existence. Since no complicated element is used, high speed processing is realized as the amount of calculation gets smaller.

Title: Aerobic fermentation of sewage sludge or the like
Inventor: TAKEUCHI MANABU
IPC: C05F3/06
Filed: 1980-12-22
Abstract: PURPOSE: To accelerate fermentation, to facilitate aerobic fermentation and to reuse fermented material as compost, by adding a very small amount of a nitrogen component to crude material, which contains only a small amount of unstable organic matters, generated by digestion of sewage sludge.  
     CONSTITUTION: Sewage sludge is digested as disposal of sludge. When the  sewage sludge, in which the content of unstable organic matters or an ignition loss is low, is aerobically fermented, the water-retaining rate of the resultant dewatered cake is high. In this regard, additives or circulating matters, e.g. cortex or sawdust, are added to the sludge, however the content of the unstable organic matters is further lowered. In addition, the dewatered cake may be solar-dried or hot air-dried to lower its water-retaining rate, however its ignition loss is reduced. Thus, a component mainly comprising ammonium sulfate or urea is added as a nitrogen source at the weight ratio of 0.1W1.5% to crude material, to be fermented, in which the rate of unstable organic matters is 30mgO 2 /g or the ignition loss is 30% or lower. In addition, the aerobic fermentation is accelerated by letting air, which is fed into a fermenting vat for aerobic fermentation, contain ammonia gas.
