Patent GB-888915-A (GB)
Abstract: 888,915. Electrocapillary instruments. UNION CARBIDE CORPORATION. Nov. 27, 1959 [Nov. 28, 1958(2)], No. 40318/59. Class 40 (4). A transducer comprises a pair of compartments 28, 3( containing electrodes 32, 34 and each containing an electrolyte solution comprising a reversible redox system, the outer walls 14, 16 being flexible diaphragms, and a porous disc 18 having a slit permitmitting fluid flow therethrough, and containing a detecting electrode 24. The disc 18 may be of porous glass. The detecting electrode 24 may have a surface of pyrolitic carbon or platinum and is provided with bosses which position the cathode in the slit whilst permitting fluid to flow past it. The electrolyte may be a solution of iodine and potassium iodide and when battery is connected across electrodes 32, 34 the negative iodine ions flow to the anode 40 so that compartment 30 contains a concentration of ions and compartment 28 a deficiency thereof. Diffusion of ions through the slit produces a standing signal on the electrode 24. Pressure on the diaphragm 16 and consequent fluid flow through the slit increases the signal detected by the electrode 24. The electrodes may be of platinum or other noble metal, but preferably consist of pyrolitic carbon obtained by the decomposition of a material such as methane, benzene, propane or naphthalene at a high temperature, the carbon thus formed being deposited on a substrate of carbon, metal or refractory such as quartz. The redox system instead of being of the iodine-iodide type may be of the ferrocyanide-ferricyanide type or of the cerous-ceric type. The solvent may be an alcohol-water mixture. The instrument is responsive to frequencies of up to 100 c.p.s.

Title: A passive method and system for detecting, locating and identifying objects having magnetic properties
Inventor: DEVAUD JACQUES
IPC: G01V3/08
Filed: 1989-03-15
Abstract: A passive method is provided for detecting, localizing and identifying magnetic objects moving with respect to one or more magnetometric sensors M1, M2, wherein the signals) from the sensors after filtering are subjected to analytic projection using basis signals (figure 2B) representative of the dipolar or quadripolar signals. Computation of an energy criterion with respect to total energy or the energy of the noise present makes it possible to provide a detection signal, the maximum value of the criterion giving localization of the object, the relative speed of the object and of the sensors. Use of two sensors allows complete localization of the object and computation of its magnetic moments. The basis signals are numerical values at discrete points of a coordinate system D, E defined by the sensors, the object and their relative motions (figure 3). The object may be minerals or a ferromagnetic body for example.

Title: Capacitors for dram cells
Inventor: KANG YOUNGTAE
IPC: H01L21/8242
Filed: 1991-01-21
Abstract: In a dynamic random access memory cell array having trench and stacked capacitors, the punch-through phenomenon is prevented by providing a difference between the trench depths (11, 12) of adjacent trench capacitors. Further, the insufficient capacitance of the capacitor having a shallower trench is compensated by making the area of the electrode (15) of the associated stacked capacitor larger than the area of the electrode (16) of the stacked capacitor of the memory cell having a deeper trench capacitor. Thus, the coupling phenomenon liable to occur between the stacked capacitors can be prevented, thereby providing a DRAM cell applicable to ultra large scale integrated circuits. <IMAGE>

Title: Proportional light scattering sensor for particles
Inventor: ELLWOOD STEPHEN HENRY
IPC: G08B17/107
Filed: 1992-12-15
Abstract: In a light scattering sensor for detecting particles in air e.g. smoke from a fire, radiation reaches receiver 3 from source 1 by a direct path 5, and from source 2 either by scattering or reflection from the surfaces 4 or due to airborne particles. The ratio of the radiation outputs from sources 1 and 2 is accurately controlled by electronic means 8 and 9, such that the signal received from source 1 is substantially equal to the standing scatter level signal from source 2 via surface 4. Difference signals or ratio changes are due to particles, and it is these rather than the absolute signal levels which are used to sense the particle concentration. Advantages include that a high sensitivity may be achieved in the presence of a relatively large standing scatter level, the sensitivity is largely unaffected by drifts and contamination, and differences in radiation scattering as function of position, wavelength or angle may be more readily employed. <IMAGE>
