Patent EP-0287321-A2 (EP)
Inventor: PAVIO ANTHONY M JR
IPC: H03C1/52
Filed: 1988-04-12
Abstract: A modulator comprising two differential FET pairs (1, 3) each pair having a current generator (5, 11) feeding the source electrodes thereof, a voltage source being coupled between the drain electrodes of each pair and the current generator. A low frequency signal is applied to one of the gate electrodes of each pair (1, 3), ninety degrees out of phase with each other and a high frequency signal is applied to the other of the gate electrodes of each pair, ninety degrees out of phase with each other. The result is that all of the generated frequencies except one side band is cancelled at the drain electrodes of the pairs. The particular side band recovered is determined by the direction of the ninety degree phase shift between the signals.

Abstract: This invention relates to a static random access memory (RAM) circuit, especially a static RAM circuit in which the data stored in a memory cell is readout by detecting a transit of address signal level. That is, an address transit pulse is generated by detecting an address signal transition, and the first and the second pulses are generated by detecting a start edge and an end edge of said address transit pulse respectively. The first pulse enables a selected word line for reading out the data stored in selected memory cells. The second pulse enables an data output circuit coupled to the bit lines for transferring said readout data to an output terminal. Under such construction, memory access operation becomes higher, and even if "skew" phenomenon is caused, the transient data readout from the memory cells instantaneously are prevented from transferring to the output terminal.

Abstract: An attachment for supersonic thermal spray equipment by which inert shield gas is directed radially outwardly about the central core of a supersonic, particle-carrying flame to isolate the same from ambient atmosphere. The shield gas is injected tangentially against the inner sur­face of a constraining tube attached to and extending from the discharge end of the thermal spray gun nozzle, causing the shield gas to assume a helical flow path which per­sists until after it exits the tube and impacts the work piece. A process using the shielding apparatus with a high-velocity, thermal spray gun and employing oxygen and hydrogen as gases of combustion and inert gas to introduce metal powder, having a narrow particle size distribution and low oxygen content, into the high-velocity combustion gases, produces significantly improved, high-density, low-­oxide metal coatings on a substrate.
