Patent EP-0376252-A2 (EP)
Inventor: NISHINO HIROTAKA
IPC: H01L21/311
Filed: 1989-12-27
Abstract: An oxide film such as native oxide film can be etched by forming a haloid or a liquid containing hydrogen halide, which is produced by a gas reaction such as one between a halogen-containing gas and a basic gas, on the oxide film. The etching proceeds mainly in a chemical reaction. So, the excellent etching selectivity of the oxide film with respect to underlying substrate is obtained, and the substrate receives no damage by the etching. Furthermore, the etching can be carried out before processes such as etching, deposition, oxidation, diffusion, or epitaxial growth are carried out to the substrate. The processed layer formed on the substrate, therefore, does not contain any useless native oxide.

Abstract: Liquid fabric softening compositions for use in a rinse bath after washing fabrics with a detergent. The softening composi­tions contain certain specific water-soluble, light-stable dyes as colorants at levels which provide consumer acceptable colors. The colorants are added to the finished composition so that the dyes are predominately outside of the dispersed softener phase, where they remain. The compositions are very desirable in that they are very unlikely to stain fabrics.

Abstract: Apparatus and method for cutting a tire surface to remove selected portions of rubber from the tire surface while the tire is rotating, and thereby improve the force variation characteristics of the tire. The material is removed by a cutting device such as a grinding wheel (32) and a positioning device (28) which holds the cutting device in a fixed cutting position for an incremental period of time while a corresponding incremental segment of the tire circumference, for instance a segment equal to 1/100 of the circumference (3.6°), passes by the cutter. A sensing device (14,22) measures a characteristic of the tire, such as its radial force variation, and radial run-out of the tire is also measured. Based on these measurements, a computing device (20) determines the amount of material to be removed from each incremental segment of the tire circumference and controls the positioning device so that the cutter is located in the correct position for removing the desired amount of material from each incremental segment of the tire circumference.

Abstract: A binder is applied to tobacco filler which is then treated e.g. by drying, to make the binder substantially non-tacky. The filler shreds are formed into a rod in which they adhere to one another as a result of activation of the binder. The rod is then treated as necessary to bond the shreds together. 
     This method allows the formation of a tobacco rod which has a high percentage of voids but maintains the requisite firmness, as shown by curves 20 and 22 contrasted with curve 14 for a typical commercial cigarette.

Abstract: A transponder (18) for detecting electromagnetic radiation at a first predetermined frequency includes an amorphous, magnetostrictive, ferromagnetic wire (19), which, when excited by electromagnetic radiation at a first predetermined frequency while in the presence of a DC magnetic bias field, transmits electromagnetic radiation at a lesser second predetermined frequency that is a frequency-divided quotient of the first predetermined frequency. The frequency dividing-wire (19) is produced by flash annealing an amorphous ferromagnetic alloy wire that has been cast by first melting and then quenching the alloy. A useful article (20) containing a transponder (18) including a frequency-dividing wire (19) may be verified as to its authenticity with a presence detection system, in which: electromagnetic radiation (28) at the first predetermined frequency is transmitted into a surveillance zone (30); the frequency-dividing wire (19) detects the transmitted radiation (28) at the first predetermined frequency and responds thereto by transmitting electromagnetic radiation (32) at a lesser second predetermined frequency that is a frequency-divided quotient of the first predetermined frequency; and a detector (24) detects the transmitted radiation at the second predetermined frequency. The transponder (18) also includes a tube (21), which encloses the wire (19) within the article (20) in such a manner as to enable the wire (19) to mechanically vibrate when excited by an electromagnetic field at the characteristic first predetermined frequency of the wire.

Abstract: A method for block averaging data from dynamic, repeating input signals, for example frequency modulated signals, takes into account the time variability of the measurement sampling. Each block of data is referenced to a synchronizing stimulus, and measurements are averaged both on the time axis and on the modulation axis. On the time axis, the time alignment for each individual measurement is placed at the center of the time interval during which the measurement was made. For each block of data acquired, the measurements blocks are averaged together in both dimensions, time (x-axis) and modulation (y-axis result being computed), using a stimulus synchronizing signal provided by the user as a time reference (time=0). The stimulus synchronizing signal should be a stable reference with respect to the modulation function being measured. For example, if frequency vs. time is being measured, the reference should identify a repeating frequency reference. The times from the stimulus synchronizing reference to the input signal events are measured and accounted for in the averaging method of the invention.

Abstract: The present invention concerns a non-linear transfer function generator, e.g., for implementating "white stretch" of a luminance signal. Specifically, first (196) and second (198) emitter-­follower amplifiers have their inputs coupled in parallel and their outputs coupled in series via first resistor (210) of a voltage divider. A second resistor (216) of the voltage divider is coupled to a point (218) of reference potential. A bias source is coupled to the second amplifier, e.g., via the second resistor of the voltage divider, so that the dynamic response of the second amplifier to an input signal is limited with respect to the first amplifier. The output signal of the first amplifier is linear and an output signal developed at the output of the second amplifier is non-linear. The linear and non-linear output signals are combined by a current steering network (188) in response to a control signal (Vc) representative of a characteristic of a processed version of the luminance signal.
