Title: Method for purification of carboxylic acid and/or anhydride thereof
Inventor: COOPER JEREMY BERNARD
IPC: B01D3/06
Filed: 1992-10-02
Abstract: PURPOSE: To efficiently purify the subject compd. which is useful as an industrial chemical product by preparing carboxylic acid mixed with iodide by liquid phase carbonylation using a carbonylation catalyst, iodine-contg. accelerator, etc., and vaporizing impurities in a vaporizing device.  
     CONSTITUTION: A liquid compsn. is obtd. in a continuous reactor by cabonylation reaction of methanol, methyl acetate and water with a carbonylation catalyst (e.g. rhodium catalyst) in the presence of an iodine-contg. accelerator (methyl iodide) and an iodine-contg. accelerator assistant (e.g. N,N-dimethylimidazolium iodide). The obtd. liquid compsn. is sent from the carbonylation reactor 20 through a line 1 to a pre-flashing vaporizer 2 equipped with scrubber plate 3 and an inlet 4 for a recirculated liquid. The liquid fraction comprising the carbonylation catalyst and iodine-contg. promoter is recirculated through a line 6 to the reactor 20, while the vapor fraction comprising carboxylic acids and iodine-contg. accelerator is discharged through a line 5. The iodine compd. mixed in the gas fraction is separated in a distillation tower 7 to purify the carboxylic acids and/or anhydrides of those.

Title: 1h-pyrrolo-[1,2-b][1,2,4]triazole derivative and its production
Inventor: MORITA KENSUKE
IPC: C07D487/04
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound useful as a medicine, dye stuff, or the like., in a short process and in a good yield by using a triazole derivative having a specific structure as a reaction raw material. SOLUTION: This method is to obtain an objective compound of formula II or III (A is a non metal atomic group necessary for forming an azole ring together with N atom; X, Y are each a non metal atomic group necessary for forming a 5-membered ring together with CONCO; the bond between X and Y represents a single bond or a double bond) by using a triazole derivative of formula I (R1 to R3 are each H or a substituting group) as a reaction raw material. Preferably, first, the compound of formula I is converted into a compound of formula IV and then the objective compound is obtained. In converting the compound of formula I into the compound of formula IV, it is preferable to use cuprous (I) chloride as a catalyst and a mixed solvent of an aromatic hydrocarbon-based solvent such as benzene with an aliphatic hydrocarbon-based solvent such as hexane as a solvent. By reacting the compound of formula IV with e.g. an acid anhydride, the compound of formula III is obtained. Further, the compound of formula III is a new compound.

Title: Print controller for printer
Inventor: NAGAHASHI NORIAKI
IPC: B41J2/51
Filed: 1993-10-22
Abstract: PURPOSE:To average a dot density and to suppress noise by selectively supplying drive and pseudo-drive currents by a print head controller, and generating a pulse at a pseudo-signal at next timing by a microprocessor when a pin is not driven by next print timing but driven at next timing after the next timing. CONSTITUTION:When pseudo-drive transistors Tr1A,..., Tr23A are conducted, transistors Tr1B,..., Tr23B are interrupted, switching circuits Q1,..., Q23 are turned ON, and pseudo-currents flow to coils L1,..., L23 only for a time corresponding to a first pseudo-drive pulse width. Accordingly, since a rebound force of previous time is applied to an elastic force of a leaf spring similarly to that at the time of driving continuously drive pin at second time and following times, the pin is accelerated to increase its impact force. As a result, a forming dot of a one-shot drive pin and a forming dot at a first time by the continuously drive pin can be made in the same density as that of a forming dot after second time and following times by the continuously drive pin, thereby improving a print quality level.

Abstract: PURPOSE: To measure radioactive rays in a constant simple process at all times by providing a radio ID card with identification data of a subject and a radio ID card reader, etc. CONSTITUTION: When it is detected that a subject 9 enters a measuring room 10, a data processor 7 controls a screen of a display device 4 and a voice generator 11 and starts guidance. The subject 9, following the guidance, inserts his or her hands to hand detection switches 5a, 5b. If the subject is at a fixed position in the measuring room 10, the whole system is turned ON, whereby a radio ID card reader 6b reads card data from a radio ID card 8 and extracts the IC number of the subject 9. At the same time, radioactive rays are started to be measured by each radiation detector 3a. The contamination level is judged by the device 7. If the level is lower than a limit, the subject is allowed to go out of the room. If the level is as high as to be controlled, contamination measuring data are preserved and managed in pairs with the IID number in the device 7.  If the contamination level is such that permits the person to leave the room, an exit gate 2 is opened to let the subject 9 out.
