Abstract: A reactor comprises a plurality of triple tubes having reaction tube, inner tube and central tube and disposed in a main body of the reactor, a first supply port formed in the main body and communicated with the central tube, and a second supply port formed in the main body and communicated with an annular space of triple tubes. The raw material introduced from the first supply port is fed into the catalyst layer to permit the reaction of the raw material to take place, and that as the activity of the catalyst is gradually lowered, the quantity of raw material to be fed to the first supply port is correspondingly reduced, and the quantity of raw material corresponding to this reduction of raw material is fed from the second supply port to the catalyst layer charged in the annular space.

Abstract: A granular form of nonionic cellulose ether is prepared by adding dropwise or spraying an aqueous solution of wetter to a nonionic cellulose ether powder while fluidizing the powder, for thereby granulating, and drying. Granulation is accomplished without grinding. The granulated nonionic cellulose ether has the advantages of quick dissolution in water and minimized dusting.

Abstract: A method of manufacturing a synthesis gas containing hydrogen and carbon monoxide comprises steps of removing only hydrogen sulfide from a natural gas containing hydrogen sulfide and carbon dioxide by permitting the natural gas to pass through a hydrogen sulfide-removing device filled with a hydrogen sulfide absorbent, adding carbon dioxide and steam to the natural gas which the hydrogen sulfide has been removed to prepare a mixed gas, and feeding the mixed gas into a reaction tube of a reformer, thereby permitting mainly a steam reforming reaction to take place in the mixed gas. This method enables hydrogen sulfide in natural gas to be removed while permitting the carbon dioxide of natural gas to be effectively utilized, thereby reducing the quantity of carbon dioxide to be added to the natural gas to be transferred to the reformer.

Abstract: An Internet communication control apparatus and its transmission control method is provided, to which communication terminals such as facsimile apparatuses and/or telephones are connected, that is connected to the Internet to perform transmission/reception with other communication terminals. When an off-hook state of a connected communication terminal is detected upon transmitting, a setting for dial tone signal reception is prepared, and the received signals are converted to a destination number. By checking the corresponding table, the destination number is converted into a destination address, and according to the content of the table, whether the communication is for facsimile transmission or telephone call is determined. According to the result of the determination, a facsimile process or telephone process is selectively performed so that the transmission operation does not seem abnormal and complicated.

Abstract: The lower part of a material to be molded forms a lower, seal with a die. A punch applying a molding force to the material forms an upper seal with the perimeter of the die. The space between the upper and lower, seals forms a pressure chamber that is filled with a fluid. As the punch descends into the die, the fluid is pressurized. The lower seal is a complete seal to prevent leakage of fluid into the die. The upper seal is given a clearance with the die that permits controlled leakage of fluid therepast at a rate that limits the maximum pressure in the pressure chamber while permitting the development of an adequate pressure on the material being molded.
