    摘要: A method for removing sulfur dioxide from waste gases by a wet oxidation-absorption method, which is characterized in that an aqueous solution of ammonium sulfate acidified with sulfuric acid at a pH range of 3 - 4 is used as the absorbent. The SO.sub.2 contained in the waste gases is absorbed with the aqueous solution of ammonium sulfate in an absorption tower and then oxidized with air or oxygen to be converted into sulfuric acid in an oxidation tower.

    摘要: An unlocking system is used with cards each having recorded thereon a secret number, a plurality of subnumbers, a specifying code for selecting at least one of the subnumbers, and an effective period. The system comprises a card reader for reading the data recorded on the card, a memory for storing a secret number, specifying code and effective period, and a processing unit for unlocking. The processing unit reduces the effective period stored in the memory by 1 in terms of unit time, e.g. 1 day, upon lapse of every unit time, e.g. 1 day or 24 hours. The unit further compares the secret number on the card with the secret number in the memory and gives an unlocking instruction when a match is found between the two secret numbers, with the effective period in the memory exceeding a predetermined period, e.g. 0. When the secret number on the card is not identical with the secret number in the memory, the processing unit checks whether or not the two secret numbers are in a predetermined relation established with use of the subnumber selected by the specifying code in the memory from among the plurality of subnumbers on the card, and gives an unlocking instruction and stores in the memory for renewal the secret number, the effective period and the specifying code on the card.

    摘要: A numerical value control system that controls a machine tool, by calculating a move command from a work program or a work data for a numerical value control unit, and directly inputting the move command to a servo control section (103) within the numerical value control unit (100) from the outside of the numerical value control unit (100). The numerical value control system comprises at the outside of the numerical value control unit: an analyzing unit (111) which analyzes a work program or a work data; and an interpolating unit (112) which carries out interpolation for each axis in a position control period of the servo control section based on output information from the analyzing unit (111) and cut conditions, where by the numerical value control system controls a machine tool by directly inputting a move command of a binary format prepared in advance by the interpolating unit (112), to the servo control section (103) within the numerical value control unit (100).
