摘要： A polymer slurry formed by polymerizing ethylene or propylene optionally with other olefin monomer copolymerizable therewith in a hydrocarbon solvent such as propylene, propane, butane, etc., is continuously or intermittently supplied to a filter having a filtering surface on which a slight quantity of polymer particles are retained. Most of the hydrocarbon solvent is recovered by passing through the filtering surface, and the polymer particles are overflown from the filter to recover as a wet cake. By the use of such a specific filter, the quantity of the solvent to be vaporized can be greatly reduced.

摘要： A light beam is applied to an information recording medium to record information. A light amount of the light beam reflected by the recording medium is detected simultaneously with the recording of information. A defect of the recording medium is detected by comparing the detected light amount with a reference value. When a degree of the detected defect exceeds a predetermined level, the information is rerecorded on another portion of the recording medium.

A discriminating device judges that the workpiece is being machined by the tool when levels of output signals generated from at least two of the vibration sensors are higher than respective predetermined threshold levels, and judges that the workpiece is not being machined by the tool when the level of an output signal generated from less than two of the vibration sensors is higher than a predetermined threshold level. Also disclosed is a method for discrimination between the machining and non-machining states.
