Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To obtain the subject acid anhydride useful as a raw material of a medical agent, an agricultural agent, etc., or a catalyst at a high selectivity and a high yield by reacting trifluoromethanesulfonic acid with phosphorus pentoxide instead of diphosphorus pentoxide.

Preferably, an adding amount of the component B is 0.2-0.6 mol based on 1 mol of the component A. Preferably, the temperature at adding of the component B is <=40 deg.C and the reaction temperature is 20-80 deg.C. By the process, a coagulation of the reaction solution with a by-product generated in a case of using diphosphorus pentoxide is diminished and the reaction can be continued, and the product can readily be separated and purified by distilling after the finish of the reaction because all of the unreacted raw materials and the reaction products are liquids.

Title: Automatic ticket examination system
Inventor: ITO NOBUHIRO
IPC: G07B15/00
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To make an automatic ticket examination system able to accuratedly judge whether each user is allowed or disallowed to pass without performing a process double for one user by composing the system of a judging means which judges whether a user is allowed or disallowed to exit according to a radio recording medium for the user judged by a judging means. SOLUTION: A CPU 21 compares a combination number (X2) recorded on a 2nd read radio card (C2) with a combination number (X1) recorded on a 1st read radio card (C1) to judge whether they match with each other. When their mismatching is judged, the CPU 21 judges that they can not be combined and ends the existing process without making any combination judgement. Thus, it is judged whether the identifiers recorded on the radio cards match with each other and when they do not match with each other, no combination judegment is made to prevent a process for an ineffective combination such as a combination of radio cards.

IPC: C25B1/00
Filed: 1978-04-10
Abstract: PURPOSE:Many Ti (alloy)-made porous substrates are spacedly arranged at a proper distance as multi-layer anodes and cathodes are placed at both sides. By using such device, an electrolyte containing MnSO4 is elecrolyzed at specified maximum and minimum potential differences between each electrode and electrolyte, thereby providing uniform MnO2 electrodeposited catalyst at one time operation. CONSTITUTION:Grating or net like formed Ti (alloy)-made porous substrates are faced in plural to be made into a plural anode 12. At both sides of the anode, cathode 11 are located through electrolyte 14 essentially consiting of sulfuric acid and MnSO4 . Voltage from the power source 13 is applied to both anodes and cathodes for electrolysis to uniformly precipitate and electrodeposit MnO2 on each of the anodes 12. The potential difference between the point B at the center of the anodes 12 and A is restricted below 6.OV, where the B has the maximum electrolyte potential difference from the cathode 11 and the A the minimum. Such potential condition limits the variations of the deposition within 10%, thereby providing MnO2 catalyst having uniformly distributed MnO2 on the anode substrates.
