TWO:Would you prevent crimes, then see that enlightenment accompanies liberty. The evils that flow from knowledge are in inverse ratio to its diffusion; the benefits directly proportioned to it. A bold impostor, who is never a commonplace man, is adored by an ignorant people, despised by an enlightened one. Knowledge, by facilitating comparisons between objects and multiplying men��s points of view, brings many different notions into contrast, causing them to modify one another, all the more easily as the same views and the same difficulties are observed in others. In the face of a widely diffused national enlightenment the calumnies of ignorance are silent, and authority, disarmed of pretexts for its manifestation, trembles; whilst the rigorous force of the laws remains unshaken, no one of education having any dislike to the clear and useful public compacts which secure the common safety, when he compares the trifling and useless liberty sacrificed by himself with the sum-total of all the liberties sacrificed by others, who without the laws might have been hostile to himself. Whoever has a sensitive soul, when he contemplates a code of well-made laws, and finds that he has only lost the pernicious liberty of injuring others, will feel[246] himself constrained to bless the throne and the monarch that sits upon it.

Great attention is recently being paid to global environmental issues, and it is now conceivable that companies will need to treat used solvents themselves. In consideration of this kind of social issue, we have developed a “membrane separation type solvent dehydration system,” which uses a polyimide membrane with superior dehydration properties developed by Ube Industries, Ltd. in combination with our own distillation and concentration technology that has resulted in solvents being more easily recovered.

THREE:

• 1Under the distillation system, even in case of azeotropic solvent compositions, this system which remove water vapor by the polyimide membrane will easily dehydrate.
• 2In comparison with the distillation system, it significantly saves on use of steam.
• 3Dehydration can be performed through merely supplying evaporated vapor to the membrane module and maintaining the differential pressure between the permeable side and the impermeable side.
• 4Solvent purity of 99.9% or more can be achieved by carrying out dehydration with a polyimide membrane only.
• 5The polyimide membrane has superior heat and solvent resistance. Therefore, the vapor permeation system reduces contamination of the membrane and thus extends its life.

THREE:But punishment bears much the same relation to crime in the country at large that it does in the metropolis. Let one year be taken as a fair sample of all. The total number of indictable offences of all kinds reported to the police in 1877-8 was 54,065. For these offences only 24,062 persons were apprehended. Of these latter only 16,820 were held to bail or committed for trial; and of these again 12,473 were convicted and punished.[52] So that, though the proportion of convictions to the number of prisoners who come to trial is about 75 per cent., the proportion of convictions, that is, of punishments, to the number of crimes committed is so low as 23 per cent. Of the 54,065 crimes reported to the police in one year 41,592 were actually committed with impunity; and[95] thus the proportion which successful crime of all sorts bears to unsuccessful is rather more than as four to one.[53] So that there is evident truth in what a good authority has said: ��Few offences comparatively are followed by detection and punishment, and with a moderate degree of cunning an offender may generally go on for a long time with but feeble checks, if not complete impunity.��[54]

The aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.

THREE:The lighting of a city by night at the public expense; the distribution of guards in the different quarters; simple moral discourses on religion, but only in the silent and holy quiet of churches, protected by public authority; speeches on behalf of private and public interests in national assemblies, parliaments, or wherever else the majesty of sovereignty resides��all these are efficacious means for preventing the dangerous condensation of popular passions. These means are a principal branch of that magisterial vigilance which the French call police; but if this is exercised by arbitrary laws, not laid down in a code of general circulation, a door is opened to tyranny,[221] which ever surrounds all the boundaries of political liberty. I find no exception to this general axiom, that ��Every citizen ought to know when his actions are guilty or innocent.�� If censors, and arbitrary magistrates in general, are necessary in any government, it is due to the weakness of its constitution, and is foreign to the nature of a well organised government. More victims have been sacrificed to obscure tyranny by the uncertainty of their lot than by public and formal cruelty, for the latter revolts men��s minds more than it abases them. The true tyrant always begins by mastering opinion, the precursor of courage; for the latter can only show itself in the clear light of truth, in the fire of passion, or in ignorance of danger.

• 1 Recovery of the detergent solvent Recovery of the cleaning solvent such as electronic parts industry, precision instrument industry.
• 2Solvent recovery and the refinement Solvent recovery and the refinement such as chemical industry, an industry of medical supplies, food industry, the fermentation industry.
