摘要:
An apparatus for discriminating a machining state from a non-machining state in a machine tool wherein a workpiece is machined with a cutting tool or grinder, comprising plural vibration sensors including at least one acoustic-emission sensor, which detect vibrations of different frequency bands, respectively, which are produced during machining of the workpiece by the tool. 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.

A surface-emitting laser device includes a transparent dielectric layer provided in an emitting region and configured to cause a reflectance at a peripheral part to be different from a reflectance at a central part in the emitting region. In the surface-emitting laser device, the thickness of a contact layer is different between a region having a relatively high reflectance and a region having a relatively low reflectance in the emitting region. The contact layer is provided on the high refractive index layer of an upper multilayer film reflecting mirror, and the total optical thickness of the high refractive index layer and the contact layer in the region having the relatively low reflectance is deviated from an odd number multiple of a one quarter oscillation wavelength of laser light emitted from the emitting region.

Disclosed is a transformation method whereby an ability to produce a useful substance of a stramenopile can be improved. The method for transforming a stramenopile comprises transferring a foreign gene into the stramenopile which is a microorganism belonging to the class Labyrinthula, more specifically, to a genus Labyrinthula, Altornia, Aplanochytrium, Schizochytrium, Aurantiochytrium, Thraustochytrium, Ulkenia, etc. Said foreign gene, which is a gene relating to tolerance against an antibiotic, a colorimetric protein and/or a fatty acid desaturase (Δ5 desaturase gene, Δ12 desaturase gene and/or ω3 desaturase gene), is transferred by using the electroporation or gene-gun technique.
