Patent EP-0720295-A2 (EP)
Inventor: ISHIMURA TAMIHIRO
IPC: G11C11/408
Filed: 1995-12-13
Abstract: A PMOS 21 and an NMOS 22, which are connected in series between a power supply potential Vcc and a ground potential Vss, perform ON and Off operation in accordance with data signals G1 and G2 from an output buffer control circuit 40, and generate an output signal. A Vpp generating circuit 50 generates a potential Vpp higher than the power supply potential Vcc and a back gate bias of the PMOS 21 is set at the potential Vpp. Even if a latch-up trigger current due to a surge voltage is produced, the back gate bias of the PMOS 21 is set at Vpp and therefore a potential difference caused in an N type well resistor becomes small and a base potential of a parasitic bipolar transistor disposed between the N type well 2 and a substrate 1 becomes approximate to the potential Vpp. Accordingly, the current which flows into the substrate 1 is suppressed and a latch-up tolerance is improved.

Abstract: A loadbreak switch (10) is provided that utilizes a pivotally mounted movable jaw contact (14) and a main stationary contact (16) that is positioned in the middle of an arc runner (40). For operation at voltages 15kV and above, the switch (10) utilizes a shunt contact (42) that bridges the arc runner (40) and that is above and coplanar with the main stationary contact (16). A magnetic field is developed by the current that flows through a coil of wire (44) disposed around the arc runner (40). This configuration when utilized in an environment of insulating gas, provides efficient extinguishing of arcs upon opening of the contacts. Further, the open jaw contact is easily visible to establish an open gap.

Abstract: An acoustic echo canceler (10) includes an adaptive filter circuit (12) and a near-end speech detection circuit (14). The adaptive filter circuit (12) includes an adaptive filter that may be of a single or dual filter structure for generating an e(t) acoustic echo canceler output signal (26) in response to an s(t) far-end speech signal (20) and an x(t) send-in signal (28). 
     The near-end detection circuit (14) receives the s(t) far-end speech signal (20) and the x(t) send-in signal (28) at a high pass filter (32) and a high pass filter (36), respectively. The filtered s(t) far-end speech signal (20) and the filtered x(t) send-in signal (28) are averaged over a selected sampling period by a far-end sampling circuit (34) and a send-in sampling circuit (38). A divider circuit (40) generates a  γ(t)  acoustic echo path gain/loss signal (42) in response to the filtered and averaged            s     ¯             (t)  far-end speech signal (20) and            x     ¯             (t)  send-in signal (28).

Abstract: A magnetoresistive ("MR") sensor (100) constructed with a concave shaped edge (102) in order to provide an effective longitudinal bias field in the center of the active MR element sufficient to obviate multi-domain states and concomitant Barkhausen noise. Utilizing the concave shape proposed herein, the "stripe height" of the element is at a minimum (SHMIN) in the center of the active region (ARL) and increases toward the off-track boundary. In a preferred embodiment, a substantially constant effective longitudinal bias field may be obtained throughout the active MR element if the stripe height increases as an exponential function of the square of the off-track distance. The principles of the present invention are likewise applicable to use in spin valve ("SV") and other giant magnetoresistive ("GMR") sensors.
