IPC: B01D61/36
Filed: 1991-08-30
Abstract: PURPOSE:To prevent both swelling of a membrane and deterioration of performance by stopping only operation of an apparatus in the supply side of object liquid to be separated and continuing operation in the permeation side and supplying dry gas to the membrane or supplying liquid free from affinity to the membrane at a time for stopping operation of an organic substance permselective separator in which the organic substance permselective pervaporation membrane is used. CONSTITUTION:At a time for stopping operation of an organic substance permselective separator in which an organic substance permselective pervaporation membrane 1 is used, only operation of an apparatus in the supply side of object liquid to be separated is stopped and operation in the permeation side is continued. Dry gas is supplied to the membrane 1 or liquid free form affinity is supplied to the membrane 1. As a result, both expansion of the pervaporation membrane and deterioration of performance based on the object liquid to be separated can be prevented after operation is stopped.

IPC: G06F17/22
Filed: 1985-10-03
Abstract: PURPOSE:To attain an exact information processing by comparing an inputted word, etc. with a reference shape and correcting a part that is not agreed fitting to the reference shape. CONSTITUTION:For example, when tan operator inputs 'ki yo u' (expressed by Japanese syllabary) instead of 'KYO' (today, expressed by Chinese character) that is to be inputted by an erroneous operation, the 'ki yo u' is displayed on a display part D and also, it is inputted to a calibration part K. At the calibration part K, the reference shape of 'ki yo u' having the same character arrangement is read referring a table in a table storage part T, and it is compared and checked with the word 'ki yo u' inputted by the operator by every character, and the correction of 'yo' is performed because the character 'yo' that is a capital letter in the reference shape is inputted in a small letter, correcting the inputted small letter 'yo' in the word to the capital letter 'yo'. And the corrected input word 'ki yo u' is stored at a storage part M. Thereby, the exact information processing can be obtained.

Filed: 1993-09-06
Abstract: PURPOSE:To inhibit cost at a low value while enabling miniaturization by conducting on/off control in response to the variation of the secondary voltage of a flyback transformer by mounting a second rectifying device. CONSTITUTION:A body diode is connected in inverse-parallel with a second switching element 11, and currents are made to flow through the primary winding 4 of a flyback transformer 5 and energy is stored when a first switching element 1 is turned on. Voltage is induced in a clamp winding 10 and currents charges a smoothing capacitor 9 through the body diode at that time, flyback voltage is generated by stored energy at the time of the ON of the first switching element 1, and high-voltage pulse voltage corresponding to a winding ratio is outputted through a rectifying device 7 even in a secondary winding 6. Since induced voltage is clamped in a rectangular wave shape when the switching element 11 is tuned on previously, flyback voltage generated in the primary winding 4 is lowered by a clamp section, and the high-voltage pulse voltage of the secondary winding 6 is lowered in response to the reduction of flyback voltage. Accordingly, a transformer for compensating voltage is unnecessitated.
