Abstract: The invention provides a novel compound 2-(3-trimethylsilylpropyl)benzothiazole having remarkable anti-tumor effects or, in particular, inhibiting growth of melanoma cells in test animals. The compound is synthesized by the ring-closing intramolecular dehydration condensation of 2-mercapto-(.gamma.-trimethylsilyl)butyroanilide which in turn is obtained by the dehydrochlorination condensation of 2-aminothiophenol and .gamma.-trimethylsilylbutyryl chloride in a polar solvent in the presence of an acid acceptor.

The compound has very low toxicity when orally administrated.

Abstract: In an automatic serum applicator so adapted as to insert blade tips of a serum applicating member into sera filled in sample trays for applying sera to said blade tips and place said blade tips onto carrier to apply said sera, an automatic applicator with serum drying-preventive mechanism adapted in such a manner that a water-absorptive sheet impregnated with water is placed in a case for accommodating sample trays, a lid covering said case is arranged in a freely openable-closable condition and said lid is opened only when the serum is to be applied to the applicating member, thereby preventing sera contained in sample trays from being dried.

Abstract: A liquid feeder comprises a liquid suction and delivery pump which withdraws a liquid such as a culture solution, buffer solution, enzyme solution or the like which is retained in a liquid storage container as refrigerated or at a reduced temperature and delivers it through a flexible tube for injection into a culture vessel located within an incubator. The tube is inserted into an inner pipe and is sealingly secured thereto. The inner pipe is detachably and hermetically mounted in an outer pipe which extends through and is secured to a wall forming an environment isolating layer of the incubator. An eccentric crankpin which is driven by a motor is connected through a link with another crankpin having a greater eccentricity, the latter crankpin being driven for rotation to cause a reciprocatory rotating motion of a driven shaft about its own axis through an angular extent of less than 180.degree..

Abstract: The invention is to drive an article into an object or extract it therefrom by means of strain energy.The article is provided at its top with an elastic part having a reaction material for giving a tensile strain or a compressive strain to the elastic part via the reaction material in order to accumulate the strain energy in the elastic part.For carrying out the driving operation, the strain energy is abruptly released from the top of the elastic part, otherwise the compressive strain is abruptly released from the bottom of the elastic part. The strain energy is transformed into a kinetic energy and the article is struck on its head by this kinetic energy so that a compressive strain wave is generated in the article being driven.For carrying out the extracting operation, the compressive strain is abruptly released from the top of the elastic part, otherwise the tensile strain is abruptly released from the bottom of the elastic part.
