Patent EP-0259872-A2 (EP)
Inventor: TRUJILLO WILLIAM R
IPC: E21B10/60
Filed: 1987-09-10
Abstract: An improved rotating drag bit for cutting plastic, sticky, water reactive and shale formations is devised by providing a plurality of large diamond cutters having a circular cutting face in excess of three quater inch in diameter. Each large cutter is provided with at least one hydraulic nozzle which in turn provides a directed hydraulic flow at the corresponding cutter face. The directed hydraulic flow is positioned to apply a force to the chip which tends to peel the chip away from the cutter face. In addition, the hydraulic flow is positioned with respect to the chip so as to apply an off-center torque to the chip which is used to peel the chip away from the cutter face and toward the gage of the bit. In particular, the nozzle defines a jet which is characterized by a direction and velocity of hydraulic fluid determined by the jet characteristics. The core is generally symmetric about its longitudinal axis and has a length along the longitudinal axis and width perpendicular thereto. The point of the jet most distant from the nozzle defines an impact point of the jet against the chip and cutter face. The longitudinal axis of the jet is chosen so that at least a portion of the jet lies between the cutter   face and the chip as it is being peeled from the cutter. Hydraulic removal of the chips is further facilitated by a plurality of junk slots having a contoured compound surface. The junk slot is characterized by having at least two distinct cross-sectional profiles, namely an asymmetric profile at its lower portion nearest the bit face and a symmetric profile along its upper portion. The asymmetric and symmetric profiles are connected by a surface providing a smooth hydrodynamic transition.

Abstract: A process for manufacturing a DMOS transistor in accordance with the present invention including the steps of forming a layer of gate insulation (12, 14) on an N type substrate (10). A layer of polycrystalline silicon (16) is formed on the gate insulation layer. A first mask is used to define the polycrystalline silicon gate. A layer of silicon dioxide (20) is then formed on the polycrystalline silicon gate. A second photolithographic mask is formed on the wafer. The second photolithographic mask defines the region where electrical contact is to be made to the polycrystalline silicon gate as well as where a deep body region (24) is to be formed in the semiconductor substrate. The deep body region is then formed. There­after, portions of the gate insulation layer not covered by the polycrystalline silicon gate are removed. The P type body region (26) and N+ source region (28) are then formed having a lateral extent defined by the edge of the polycrystalline silicon gate. A conductive layer 30 is formed on the wafer and photolithographically patterned, thereby leaving a gate contact and a source and body contact. A passivation layer 34 is then formed on the wafer, portions of which are photolithographically removed, thereby defining bonding pads. Of importance, the above-­described process uses only four photolithographic masking steps.

Abstract: This invention aims to offsetting the phase difference caused by a delay in a frequency synthesizer which is intermittently actuated for power reduction by setting the division ratio at two levels at the time of releasing reset signals at the variable frequency divider so that the delay time is adjusted by the frequency divi­sion in the first cycle. The proposed synthesizer sets the ordinary division ratio in the second cycle and thereafter, and if there is still a phase difference, it sends reset signals again to the variable frequency divider repeating the aforementioned operations. This frequency synthesizer can realise an ideal intermittent operation without significant frequency fluctuation by repeating the above operations to reduce the phase difference at the variable frequency divider to one cycle of the input signals of the counter or less (e.g. ca. 1.3 nsec in 800 MHz).

Abstract: The invention relates to an electromagnetic switchgear, in particular circuit-breaker. 
<??>With electromagnetic switchgear, in particular contact breakers, there is a significant requirement for constructing the circuit-breakers to be bounce-free. Due to the striking of the contact bridge support at the end of the switch-off process on the housing, particularly when plastics such as thermoplasts are used for the contact bridge support, rebouncing phenomena have been almost unavoidable. The present invention is intended to reduce these rebouncing phenomena substantially. 
<??>This is done by providing projections on the housing which are of unequal height in the movement direction of the armature, and which can project through openings of the contact bridge support so that the projections can come into contact with a metal part, preferably the armature itself, during switching off. 
<??>Electromagnetic switchgear with alternating current and also direct current magnet system.
