Abstract: © An intrinsically safe battery pack arrangement for electrically powering electrical devices is disclosed. The power pack has a device for electronically determining a short in a cable or device and switching off the voltage to the power pack. The electronic device includes a transisterized circuit for sensing and controlling currentthrough the cable. When the currentex- ceeds a predetermined maximum, the circuit limits the current in the cable to a maximum value. The circuit is latched in the off position when the short is present for an extended time and the circuit may be reset after the short is removed and the problem corrected. This form of circuitry in power packs for use with mining equipment such as lamps, provides a unit which will not cause hazardous sparks when shorted thereby constituting an intrinsically safe device for use in mines.

Abstract: A self-aligned silicide base contact structure for a bipolar transistor, and a process for fabricating the structure are disclosed. The structure has four key elements: a base region 36, a polycrystalline silicon emitter contact region 50, a spacer oxide 60 and 62, and a base contact 74 formed of metal silicide. The spacer oxide is an insulator that electrically isolates the side walls of the emitter contact region from the upper surface of the base region. The spacer oxide is a residual amount of oxide that is left on the side walls of the emitter contact region after anisotropic etching is used to remove most of a covering layer of oxide. The metal silicide base contact is created on an exposed upper surface of the base region, and is formed by first depositing a metal layer on the upper surface of the base region, and then heat treating. Where metal and silicon atoms are in contact, such as along the exposed upper surface of the base region, metal silicide forms.

Abstract: Technique for dynamically maintaining alignment of servo controls (12) in a disk (D1, D2) drive system which uses external indicia (Q, R) to position the head assembly (8) between tracks containing embedded servo signals; the latter used to control track following. Plural pairs of phase staggered track reference signals are derived from the external indicia (Q, R) , and during system initialization an optimal pair is selected for controlling head (8) positioning. The system is initialized both at power up time and after detection of certain errors. The selection is made by using each pair separately to direct positioning of the head assembly (8) over a predetermined range of sampling positions at each of which centering offsets relative to the embedded servo signals are measured and recorded in association with the respective pair. Based on an evaluation of these offsets, the system microprocessor (16) selects a reference signal pair having the least average offset to control subsequent head (8) positioning operations. The system is then readied for "normal" read/write operation.
