Abstract: Abstract The present invention is a method of counting auto-matically the number of etch pits by using a computerized image-processing technique, which comprises the steps of calculating the average unit area Ap of an isolated etch pit p on the surface of a semiconductor crystal substrate (wafer) for every wafer or at every measured point thereon, dividing the area Sk of a grouping of overlapping etch pits k by the average unit area Ap, rounding off the quotient to be an integer so as to obtain the number of etch pits nk included in the area Sk, and totaling the number of isolated etch pits u and the number of overlapping etch pits nk to obtain the total number of etch pits N on the wafer surface, so that the etch pits density on the wafer surface can be calculated.

Abstract: ABSTRACT OF THE DISCLOSURE      An improved process of making abrasion-resistant decorative laminate without overlay comprises simultaneously impregnating and coating a laminate decor sheet with a mixture of the liquid impregnating resin and an abrasion-resistant composition of microcrystalline cellulose and abrasion-resistant mineral particles such as alumina.  The microcrystalline cellulose functions not only as a binder material in the product, but also serves to maintain the mineral particles in suspension in the liquid resin.  The mixture is deposited onto the top surface of the decor sheet which absorbs the liquid resin leaving on the upper surface thereof an ultra-thin layer of the abrasion-resistant composition plus a small amount of resin.          After drying, the decor sheet is ready for use in the manufacture of high and low pressure decorative laminates.

Abstract: ABSTRACT OF THE DISCLOSURE       The present invention relates to a method for carrying out simultaneous heat and mass exchange operations between two input streams, where a gradient of at least 30 degrees C exists between the streams, each stream containing at least two components.  According to the invention, the two streams are introduced into a reactor containing a solid or liquid adsorbent material, which retains at least one component preferentially to the other components.  The adsorbancy power of the component by the adsorbent material is higher at lower temperatures than at high temperatures.  A stream results from the reactor in which the diluted component becomes more concentrated in respect to the input stream.  The equilibrium concentration of the adsorbable species in the adsorbent, at the conditions of the colder stream, is higher by at least 0.01 g adsorbed species per g adsorbent than that prevailing at the conditions of the hot feed.  The method is applicable to a number of processes such as gas puri-fication, distillation, process-air drying, air conditionning, air enrichement and internal combustion engines.  The method imparts appreciable savings in energy requirements and improved mass transfer efficiency for processes wherein heat and mass exchange operations are involved.

Abstract: ABSTRACT OF THE DISCLOSURE A modular assembly is provided for use in frame structures which are assembled by joining frame members to connector or fitting members to allow such structures to be easily and quickly assembled and disassembled without the need for a separate assembly tool. In the assembly the frame member telescopicallly engages the fitting member and both members are constrained from relative rotational and translational movement by a resilient retainer. The retainer has a general spring-like band configuration which includes a backbone portion having two open extending ends. The retainer is flexed over one of the joined members and its backbone engages at least one half of the perimeter of that member. The installed and tensioned length between the two retainer ends is greater than the length between the same ends in a free state, thereby clamping the structural members together. An alignment pin extends radially inwardly from the retainer backbone and engages both members to lock the retainer in place.

The  existing  frequency  (f)  of  the  resonance  oscillations  is determined and from this one ascertains the force from the formula   CO and C1 are quantities depending on properties of the beam (2, 3). The values CO and C1 can be corrected according to temperature if the beam (2, 3) is simultaneously excited into the resonance state by two frequencies (f1, f3) which are substantially in the ratio of two whole numbers to each other. A measuring apparatus comprises an oscillator (11) between to nodes (7, 8;  9,  10)  of the beam (2,  3).  A sensor  (14)  serves to detect the existing frequency. An exciter circuit (18) makes the excitation frequency follow the  resonance frequency with  the  aid  of  the  existing frequency.

Abstract: OBJECT DETECTION METHOD AND APPARATUS EMPLOYING ELECTRO-OPTICS                      ABSTRACT OF THE DISCLOSURE                   Apparatus for detecting the presence of an object within an area under surveillance employs an electro-optical emitter for directing light into the area and an electro-optical receiver for sensing light reflected from the object which originates from the emitter. The emitter emits light energy of a preselected wavelength and is modulated at a preselected frequency to provide the emanating light energy with a characteristic signature. Light reflected by an object within the area under surveillance is filtered and converted to an electrical signal which varies in accordance with the magnitude of the filtered light having the preselected wavelength and modulation frequency. A selected portion of the electrical signal is amplified by a band-pass amplifier and is synchronously sampled in accordance with the modulation frequency to determine the magnitude of the filtered light which originated from the emitter. The sampled signal is compared with a threshold value to determine whether an object is present within the area under surveillance. The emitter and receiver are covered by a transparent shield to protect them against foreign matter. An electro-optical detector monitors the accumulation of foreign particulates on the shield. The apparatus may be desirably used in vehicles to detect the presence of adjacent objects, particularly within the vehicle's "blind spots" and thereby avoid collisions.
