摘要:
The present invention relates to a fluid agitator which may stir fluid in a closed space without leakage of the fluid. The fluid agitator has a motive means and a bearing means installed in the closed space.In the fluid agitator employing a electric motor as the motive means, only the stator coil of the motor which is weak in its resistance against high temperatures and humid atmosphere is sealed in a sealing chamber. The sealing chamber may be provided with a cooling device to cool the inside thereof. The driving shaft of the motor is supported by a bearing having resistance to high temperatures and high humidity and is provided with an agitating blade.In the fluid agitator employing a turbine system as the motive means, a turbine chamber and a turbine blade are set in the closed space. A fluid supply is furnished to introduce fluid into the turbine chamber from outside of the closed space for driving and rotating the turbine blade. The turbine blade is connected to an agitating blade through a rotation transmission.

A mechanial seal having a split seal ring which is covered by a support ring over the outer face with a predetermined gap and is fastened in a circular shape by a O ring inserted in the predetermined gap. The split seal ring is easily assembled by a tool which includes a split ring body. The split ring body has a basic inner face contacting to a surface of a rotary shaft, an end face contacting to the end face of the split seal ring an a projection for inserting the O ring into the gap.

This invention provides processes for producing quinolone compounds which comprise cultivating Amycoa sp. FERM BP-4785, and then isolating quinolone compounds from the fermentation broth. The compounds produced by these processes include compounds of formula (I) wherein R.sup.1 is H, R.sup.2 is (a) and R.sup.3 is CH.sub.3 ; R.sup.1 is CH.sub.3, R.sup.2 is (a) and R.sup.3 is CH.sub.3 ; or R.sup.1 is CH.sub.3, R.sup.2 is (b) and R.sup.3 is CH.sub.3 ; and the like. The present invention also relates to a pharmaceutical composition comprising the same, which is useful in the treatment of diseases, disorders and adverse conditions caused by Helicobacter pylori and is particularly useful in the treatment of gastroduodenal disorders, diseases and adverse conditions caused thereby. ##STR1##

The present invention provides a novel culture which belongs to Actinoplanes (Actinoplanes sp. FERM BP-3832). This culture is capable of producing rapamycin more than ten times efficiently than the cultures which have been reported (e.g., Streptomyces hygroscopicus ATCC 29253). The present invention provides a process for the production of rapamycin which comprises cultivating Actinoplanes sp. FERM BP-3832 and thereafter isolating rapamycin from the fermentation mixture.

This invention provides compounds of the following chemical formula or their pharmaceutically-acceptable salts: ##STR1## wherein R is hydrogen or chloro. Also, the present invention provides a process for the production of the compound of formula I, which comprises cultivating a microorganism having the identifying characteristics of Aspergillus fischeri var. thermomutatis ATCC 18618 or the like, and then isolating the compound of formula I from the fermentation broth. The pyrrolobenzoxazine compounds of formula I of this invention have broad antiparasitic activity, and thus are useful as antiparasitic agents, especially as anthelmintics.

A double-layer coil for an electric motor is formed of a single continuous conductor with the two layers being wound simultaneously. A first length of conductor is wound about a pulley to form a coil and at the end of that coil but without breaking the conductor another coil is commenced to be wound about a rotating bobbin, with the coil of the first length wound on the pulley being caused to orbit the bobbin at a rate twice the bobbin rotation speed, whereby the conductor coil is unwound from the pulley and rewound on the bobbin at and the same time a further conductor is being wound about the bobbin to form a second coil, thereby forming both layers of the coil simultaneously.

The object of the invention is to provide a chamber for a heating press which can cope well with the height change of a composite material article. In a chamber for a heating press, upper and lower metal flanges 6, 7 are provided between upper and lower press heating plates 1, 2 and an intrusion part 11 is further formed in the lower metal flange. This intrusion part 11 is intruded into the upper metal flange 6 and the gap between the intrusion part 11 and the upper metal flange 6 is sealed by a packing 22 having a lip.
