Abstract: PURPOSE:To provide a method to efficiently obtain the subject compound useful for medicines, agricultural chemicals, etc., in a high yield by reacting a compound obtained by adding an iodine group and an acyloxy group to a double bond of anhydrodideoxythreohexoenopyranose under specific conditions. CONSTITUTION:In a compound of formula II (R is an acyl) obtained by adding an iodine group at alpha configuration to 4-position of the double bond of 1,6- anhydro-3,4-dideoxy-beta-D-threo-hexo-3-enopyranose of formula I and adding an acyloxy ion at beta configuration to 3-position of the double bond of the compound of formula I to carry out trans-addition, the acyloxy group is hydrolyzed in the presence of a base to afford a compound of formula III having an oxirane ring at beta configuration. The ring of this compound is reductively opened and the hydroxyl group is protected to give a compound of formula IV (R<1> is a protecting group of hydroxy group). The 1,6-anhydro bond and the protecting group of the hydroxy group of the compound of formula IV are hydrolyzed with an acid to provide the compound of formula V.

Title: Subscriber management system for exchange
Inventor: HARAGUCHI TADASHI
IPC: H04L12/28
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To improve the security by relieving the load of the maintenance personnel, so as to prevent block processing from giving any effect on other subscribers. SOLUTION: A management table 7a, having block information denoting whether or not each of subscribers (A)1-(C)3 is able to make address registration to an asynchronous mode transfer(ATM) exchange 100, is provided for the exchange 100. Upon the receipt of a block request of an optional subscriber from a maintenance personnel, a block-processing section 10 blocks all connections to the subscriber and sets block information of the subscriber in a management table 7a to be a block state. Upon receipt of an address registration request from any of the subscribers (A)1 (C)3, the processing section 10 rejects the address registration request, checking the block information of the management table 7a when the information indicates a block state.

Title: Treatment of waste gas
Inventor: OSHIMA MICHIO
IPC: B01D53/34
Filed: 1988-08-09
Abstract: PURPOSE:To wet-desulfurize waste gas contg. SO2 and HF with lime while maintaining the activity of CaCO3 and a high rate of desulfurization by using CaCO3 and Ca(OH)2 in a specified molar ratio as an absorbent, blowing air into an absorbing soln. and treating the waste gas by absorption. CONSTITUTION:When waste gas contg. SO2 and HF such as waste gas generated by burning coal is treated by absorption, CaCO3 and Ca(OH)2 are used in 0.5-0.99 molar ratio of CaCO3 to CaCO3+Ca(OH)2 as an absorbent and fed into an waste gas treating tower and air is blown into an absorbing soln. By this method, the inhibition of dissolution of CaCO3 due to aluminum fluoride formed by the reaction of Al contained in dust in the waste gas with HF can be prevented, so wet desulfurization with lime can be carried out while maintaining the activity of CaCO3 and a high rate of desulfurization.

Title: One-component developer for electrophotography
Inventor: YAJIMA TOSHIKO
IPC: G03G9/087
Filed: 1989-07-29
Abstract: PURPOSE:To eliminate toner dust, fogging and toner splashing by using specific polyester in a digital developing system. CONSTITUTION:The polyester obtd. by bringing a monomer compsn. contg. a trivalent and higher monomer, arom. dicarboxylic acid and aliphat. diol into condensation polymn. reaction is used as a binder resin. Since there are many ester bond parts in the diester, the affinity to a magnetic material having a hydrophilic surface increases and the dispersibility of the magnetic material when made into the toner is improved and the bond between the resin and the magnetic material increases. Since the molecular chains are flexible, the toner has a buffer property to external force and the breakage of the toner itself hardly arises. The toner dust is eliminated in this way and, therefore, the sharpness of images is improved; further, the fogging and the splashing of the toner in a machine are obviated even if printing is executed many times.

Filed: 1983-10-25
Abstract: PURPOSE:To enable all stacked cells to perform power generation of equal voltage by increasing the amount of air flow when the voltage of each cell becomes lower than the limit level so as to restore a normal voltage level. CONSTITUTION:An air-flow-amount-controlling part 9 performs closed-loop control by using an air flow amount signal (S4) so that the amount of air flow is usually controlled according to the current signal (S3) of an output current (i) from a fuel cell 3. When the amount of air flow is insufficient to supply an amount of oxygen necessary for the whole air electrode 3, one (for example S1K) of voltage signals (S11-S1N) produced by a corresponding voltage detector 5 decreases. Next, the voltage signals (S11-S1N) are compared with set limit levels (L1-LN) in comparators 71-7N. After that, the large deviation level (LK-S1K) is selected in a signal selector 8 before an air-flow-amount-correcting signal (S2) corresponding to the deviation is produced in an air-flow-amount- correcting part 6.
