摘要： This invention relates to a gas turbine combustor of a premixing combustion system in which a fuel and the air are mixed and burnt, consisting of a cylindrical main nozzle provided on an upstream end wall of a cylindrical combustion chamber, an auxiliary nozzle formed around the main nozzle, a main premixed gas supply means for supplying a premixed gas to the main nozzle, and an auxiliary premixed gas supply means for supplying a premixed gas, the excess air ratio of which is smaller than that of the main premixed gas, to the auxiliary nozzle. Owing to this arrangement, a lean premixed gas having an excess air ratio larger than 1 can be burnt stably under low to high loads of a gas turbine.

摘要： PURPOSE:To withstand sterilization treatment by high temp. steam, to enhance cooling effect from high temp. and to shorten a cycle of sterilizing work, by forming a container by the injection molding of a mixture of a steaming- resistant resin and an alloy. CONSTITUTION:A sterilizable container is formed by the injection molding of a mixture of a steaming-resistant resin and an alloy. As the steaming-resistant resin, polyether sulfone or polyether ketone low in hygroscopicity at high temp. and withstanding high temp. treatment is pref. As the alloy, a powdery or fibrous one is pref. As the powdery alloy, there are a stainless steel type, an iron-nickel type and an aluminum type, and all of them can be used. The particle size of the powdery alloy is pref. made as fine as possible and pref. 5-150mum. The mixing ratio of the steaming-resistant resin and the alloy is set so that the alloy becomes a range of 20-80wt.% with respect to the resin. Since this sterilizable container is constituted by mixing the alloy with the steaming- resistant resin, a cooling speed after sterilization treatment at high temp. is fast and sterilization treatment can be performed efficiently.

摘要： PURPOSE:To enable an adhesive sheet to be placed on a frame without any need of a peeling work by providing an adhesive tape takeup device for winding the adhesive tape rolled at one side of the frame toward the other side thereof. CONSTITUTION:This roll type dust collecting sheet removes dust in such a way that an adhesive layer 2 collects the dust adhering to the footwear or wear of people passing on an adhesive sheet 1 paid out from a rolled sheet 4 via a takeup device 5 and placed on a frame 6. Thus, bacteria adhering to the dust is not carried therewith into a clean room including a sickroom. In this case, the dust collecting sheet is so made that the adhesive tape 1 on the frame 6 is wound by length corresponding to the length thereof with the device 5, when the sheet is contaminated to a certain extent due to the passage of people and carriages, and then, a new section is paid out from the rolled sheet 4 to the frame 6. This process is repeated, and dust can be thereby removed efficiently and accurately. The type of the device 5 may be arbitrary such as manual or electric type, and the adhesive sheet 1 can easily be placed on the frame 6.
