Patent CA-2131100-A1 (CA)
Inventor: INAM ARUN
IPC: H01L27/105
Filed: 1993-02-23
Abstract: A ferroelectric memory and its method of making in which a highly c-axis oriented layer of ferroelectric lead zirconate titanate (PZT) is epitaxially deposited at between 640° and 710°C upon a crystalline film of yttrium barium copper oxide (YBCO), acting both as growth template and bottom electrode. A top electrode is formed over the ferroelectric layer to complete the memory element. The two electrodes are preferably composed of the same perovskite conductor of the same crystalline orientation, most preferably, .alpha.-axis oriented YBCO. The structure can be grown on a silicon substrate with an intermediate buffer layer of yttria-stabilized zirconia. The ferroelectric behavior is optimized if the structure is cooled from its growth temperature at about 20°C/min. Such a-axis oriented perovskite thin films can be grown by continuously depositing the same or different perovskite material, but dividing the deposition into three temperature stages, a first at a temperature favoring .alpha.-axis oriented growth, a second gradually increasing the temperature to a temperature favoring c-axis growth, and a third at the c-axis growth temperature. Nonetheless, a high-quality .alpha.-axis oriented film is grown. The memory can be rejuvenated after it has become fatigued by applying a pulse of magnitude equal to that of the writing pulse but of considerably longer duration.
Patent CA-2131821-A1 (CA)
Inventor: KLEMENTICH ERICH F
IPC: F16L15/00
Filed: 1993-02-16
Abstract: 2131821 9318329 PCTABS00025 The present invention pertains to a tubular connection (100) having a stabilized center-shoulder seal (104). The stabilization of the center-shoulder seal is achieved using at least one run-out section (114, 110) of thread adjacent to the center-shoulder seal configuration of each connection member. The run-out section of thread is typically used in combination with a run-in section of thread on the corresponding connection member. Preferably, the center-shoulder seal configuration of each connection member is positioned between a run-out thread section and a run-in thread section. (The corresponding connection member will comprise the corresponding sections of run-in and run-out threads, respectively, so there is an interengaging set of run-in and run-out threads).  Even more preferably, in addition to the connection having one set of run-out and run-in thread sections adjacent to the center-shoulder seal, the connection has a second set of run-out and run-in threads adjacent to the exterior edges of the connection (A double run-out, run-in stabilization of the center-shoulder seal). The double set of run-out, run-in sections of thread provides the most stable connection. The most preferred center-shoulder seal design is a "locked double shoulder" design (119), wherein the cross section of the assembled center-shoulder area exhibits an interlocking double shoulder configuration. The most preferred thread profile is a single hook thread profile wherein the load flank angle is a negative angle and the stab flank angle is about zero degrees. The preferred thread profile comprises chamfered stab flanks at least at locations which will come into contact upon initial telescoping of a connection pin member into a connection box member. The thread is typically a variable width thread having a progressively increasing thread width throughout a continuous section of thread.

Abstract: A light source (12) radiates an infrared beam (14) through the exhaust plume (22) of a motor vehicle (20) which passes in front of the source (12). A photosensor unit (18) includes a plurality of photodetectors (42,44,-46,48) which are spaced closely adjacent to each other and simultaneously sense the beam (14) after it propagates through the plume (22). An optical beam homogenizes or integrator (36) disposed between the plume (22) and the photosensor unit (18) causes the light incident on the photodetectors (42,44,46,48) to have uniform intensity.      The photodetectors (42,44,46,48) are sensitive to different wavelengths corresponding to spectral absorption peaks of constituents of the composition of the plume (22), including carbon monoxide (CO), carbon dioxide (CO2) and hydrocarbon (HC). A computer (24) computes the composition of the plume (22) as the percentages of the constituents based on the sensed transmittances of the respective wavelengths through the plume (22). A video camera (26) produces a video image of the vehicle license plate (28), and a combiner (24,32) causes the video image to be displayed on a video monitor (30) and recorded on a video recorder (32) together with the plume composition data.
