20100126322Method of producing a circular saw blade having cooling channels - The invention relates to a method of producing a circular saw blade having cooling channels. In that case, placing of a plurality of thread-shaped bodies on a first circular disc of plastic material is carried out in such a manner that each of the thread-shaped bodies is oriented in radial direction. A second circular disc of plastic material is then placed on the first disc and the thread-shaped bodies. Subsequently, pressure is exerted on the second disc in the direction of the first disc. Removal of the plate-shaped bodies from the compressed disc pair is thereafter carried out, whereby cooling channels are created.

20090251197Simplified Circuit to Use a Normally Conducting Circuit Element That Requires a Normally Blocking Circuit Element - An embodiment of the invention relates to a switching system that includes a depletion-mode semiconductor device, such as a silicon carbide device, coupled in series with an enhancement-mode semiconductor device, such as a silicon field effect transistor, so that a controller can be configured to disable conductivity of the series arrangement of the two switches during a transient operating condition. During normal high-frequency switching operation, the controller persistently enables the enhancement-mode device to conduct while intermittently enabling the depletion-mode device to conduct. The controller disables the enhancement-mode device to conduct during a transient operating condition such as start up or during a fault, thereby providing circuit protection during such transients. The switching system preserves low loss switching characteristics of the depletion-mode device in a high-frequency switching circuit.10-08-2009
