IPC: C07D333/10
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To purify thiophene contaminated with mercaptan, by oxidizing mercaptan to form a polysulfide and distilling thiophene. SOLUTION: Mercaptan is selectively oxidized with sulfur in the presence of preferably a solid basic catalyst to form a polysulfide. Then treated thiophene is distilled and purified. The basic catalyst is a resin containing an amine, guanidine or amidine functional group. The oxidation is carried out by using 1-10 gram atom, preferably 2-4 gram atom sulfur based on 1 mol of mercaptan at a room temperature to 120 deg.C, preferably 60-90 deg.C. The ratio of a liquid basic catalyst is 0.1-10% based on the weight of thiophene to be purified and that of the solid basic catalyst is preferably 0.5-15%.

Title: Method of maintaining temperature of oil pipe or the like
Inventor: FUJIWARA KATSUJI
IPC: F17D1/18
Filed: 1980-02-06
Abstract: PURPOSE: To heat an oil pipe and measuring instruments to maintain their temperature, by using condensate drained from a steam pipe or a steam using machine through a steam trap or a throttle valve means.  
     CONSTITUTION: The condensate of a steam pipe 1 is conducted to the vicinity of  the ground through a drip pipe 4 and drained through a steam trap 5. A drain pipe 6 is fitted on the outlet port of the trap 5 and wound around an oil pipe 3. After the condensate of the steam pipe 1 is drained through the steam (r) trap 5, the condensate heats the oil pipe 3 to maintain its temperature as the condensate flows through the drain pipe 6. In that case, a large quantity of condensate can be retained upstream to the trap 5. As a result, no water hammer occurs and the air in the drip pipe 4 can be easily discharged.

Filed: 1988-01-27
Abstract: PURPOSE:To prevent the deterioration of exhaust emission and fuel consumption by permitting the sufficient learning in each region by reducing the variation of the learning region for the air-fuel ratio control constant by the block learning control having the car speed as parameter. CONSTITUTION:When an F/B condition judging means judges the fulfillment of the air-fuel ratio feedback control condition, an A/F control quantity calculating means calculates the control constant according to the output V2 of a downstream side O2 sensor for a three-component catalyst CCRO, and the air-fuel ratio is closed-loop-controlled according to the output V1 of an upstream side O2 sensor. Further, when the learning condition fulfillment condition is judged, a learning means calculates the calculated control constant, i.e., the center value of the air-fuel ratio control quantity, and said value is memorized into each car speed region according to the car speed SPD. Since the variation of the learning region is reduced by the adoption of the block learning control having the car speed as parameter, the sufficient learning in each region is permitted, and the deterioration of fuel consumption and exhaust emission can be prevented.

IPC: H04N1/32
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent storage of undesired image data in order to suppress waste of memory capacity and to shorten an image data extracting time by storing only received image data to be extracted, collating an originating number with a previously registered number and selecting the received image data to be stored based on the result of the above collation. SOLUTION: This facsimile equipment can set a remote FAX extracting function and accordingly stores received image data in an external memory without printing them. The stored image data can be externally extracted by an external polling operation. Under such conditions, an acquired originating number is collated with a number previously registered in an opposite party register list 7a when the remote FAX extracting function is set. Then only when both numbers are coincident with each other, the image data are stored in a 2nd image memory 9 that is exclusive for the remote FAX extracting function. Meanwhile, the image data are stored in a normal 10t image memory 8 if those two numbers are not coincident with each other.
