    • A threaded connection is secured against loosening/unscrewing for columns of carbon and/or graphite electrodes. The electrodes are connected in columns with threaded connection elements, i.e., carbon connecting pins. At least one part has a wedge ramp on the root of the thread winding. When the components of the threaded connection are screwed together, the crests of the thread windings of one part abut with the wedge ramps of the other threaded connection component. A contact line is created, possibly multiple sections of a contact line. When the parts are screwed together, all forces are transferred from one part to the other only via the contact line. In a special case, the contour of the thread winding along whose root the wedge ramp is running is reduced e.g. to a connecting line between two wedge ramps located one above the other in the cross-section.

    • A disk array controller reliably detects disk drive power-on-reset events that may cause a disk drive that has uncommitted write data stored in its cache to lose such data. The methods for detecting the power-on-reset events include operating the disk drives in an ATA security mode in which a power-on-reset of a disk drive will cause the drive to enter a locked state in which data transfer commands are aborted; and tracking power cycle count attributes of the disk drives over time. When a disk drive power-on-reset event is detected, the disk array may be efficiently restored to an operational state by re-executing or “replaying” a set of write commands that are cached within the disk array controller. The invention is also applicable to single-disk-drive storage systems.

    • Transient blocking with electrostatic discharge (ESD) protection to be employed with a transient blocking apparatus that has a transient blocking core with an input, an output and at least one depletion mode n-channel device interconnected with at least one depletion mode p-channel device such that a transient alters a bias voltage Vp of the p-channel device and a bias voltage Vn of the n-channel device so that these devices mutually switch off to block the transient. The apparatus uses high-voltage depletion mode devices, e.g., MOSFETs, connected before the input and/or past the output of the transient blocking core in uni-directional and bi-directional embodiments, respectively. The ESD protection unit can be of the fold-back type and is connected between the input and output of the core to protect the transient blocking apparatus by causing the core to turn the high-voltage devices back on and shunting the core when dangerously high over-current conditions are produced by ESD events.
