    摘要: Organohalosilanes are prepared by the Rochow process of reacting metallic silicon particles with an organohalide in the presence of a copper catalyst. The metallic silicon particles, which are prepared by comminuting fragments of metallic silicon raw material, have a mean particle size of 10 &mgr;m to 10 mm and a surface oxygen quantity of up to 0.3 wt % which is given as the difference between the oxygen concentrations determined by in-metal oxygen analysis of the metallic silicon particles and the fragments, respectively.

    摘要: Hexamethylcyclotrisilazane is prepared by reacting dimethyldichlorosilane with ammonia at a temperature between -20.degree. C. and 20.degree. C. Preferably, ammonia is blown into dimethyldichlorosilane at the temperature, and the reaction mixture is washed with 20% or higher alkaline water within one hour from the end of reaction for removing ammonium chloride by dissolving it in the water. Then hexamethylcyclotrisilazane of high purity is prepared in high yields. The method can be scaled up for commercial manufacture.

    摘要: 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.. The motion of the driven shaft is effective to selectively switch the discharge port of a pair of liquid supply tubes to a position over a single vessel. The motor also drives a cam which causes a vertical motion of a drive shaft which is also angularly driven by a cam groove, the drive shaft being effective to cause a three dimensional motion of the discharge port of a single liquid supply tube for injection into a pair of vessels.
