Title: Method of and apparatus for measuring a velocity vector by use of a spatial filter
Inventor: AMARI YASUFUMI
IPC: G01P3/36
Filed: 1990-03-30
Abstract: METHOD OF AN APPARATUS FOR MEASURING A VELOCITY       VECTOR BY USE OF A SPATIAL FILTER                ABSTRACT OF THE DISCLOSURE      At least a set of two spatial filters are so arranged in a two-dimensional space or three-dimensional space that their spatial distributions are opposite to each other.  Two systems of light detection signals from a moving object are synchronously collected through the spatial filters, integrated, and photoelectrically converted into time-series electrical signals.  The electric signals are processed according to a predetermined algorithm.  A result of the process is judged as positive or negative to find the direction of a velocity of the object.  The size of the velocity is found from the two systems of light detection signals according to a known equation.  Instead of oppositely arranging the spatial distributions of the two spatial filters, at least one differential spatial filter system may be employed to provide light detection signals corresponding to those provided by the oppositely arranged spatial filters.

Abstract: Abstract of the Disclosure An aqueous phase, an oil of a triglyceride or fatty acid ester, and, per part by weight of oil, 0.05 to 0.4 part by weight of an amphoteric emulsifier are mixed together and processed in a high-pressure homogenizer into a nanoemulsion of less than 200 nm sized oil particles.          The emulsifier, exhibiting in the aqueous phase a lamellar liquid-crystalline structure, is preferably a glycero-phosphatide of the formula   Therein, R1 and R2 mean acyloxy and/or alkyl or alkenyl ether.  R3 is a tri-lower-alkyl ammonio or amino-substituted lower alkyl.  The resultant nanoemulsion is stable for a period of several months and does not contain any toxic emulsifier materials.  Therefore, it can be advantageously utilized as a vehicle for active agents, for example medicines and/or cosmetic ingredients.

Abstract: In a color television system, the color signals produced by a luma-chroma IC (154) are summed (171,173,175,177) to produce a signal representative of processed luminance information not otherwise readily available. Pulses of the summed signal corresponding to retrace blanking pulses contained in the color signals, are stripped away in order to reduce errors when attributes of the. summed signal are determined, e.g., by an average detector (183). The detector provides a control signal for modification of a luminance signal, such as by "white stretch" (136).

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus and methods are disclosed facilitating the application of forces and measurement of dimensions of a test subject.  In one arrangement the test subject is coupled to a forcing frame and controlled forces applied thereto by a series of guideways and sliders.  The sliders, which contact the test subject are in force transmitting relation to a forcing frame.  Tension, compression and bending forces can be applied to the test subject.  Force applied to the test subject is measured and controlled.  A dimensional characteristic of the test subject, such as growth, is measured by a linear variable differential transformer.  The growth measurement data can be used to control the force applied.  Substantially uniaxial stretching is achieved by placing the test subject on an elastic membrane stretched by an arrangement of members securing the elastic member to the forcing frame.

Abstract: Alkaline earth metal alkylates having a spherical particle habit are prepared by dissolving an alkaline earth metal alkylate in a solvent, adding a second solvent which dissolves the alkaline earth metal alkylate only with difficulty or does not dissolve it at all, but which is homogeneously miscible with the solution of the alkaline earth metal alkylate in the first solvent, removing the first solvent and then removing the second solvent. The particle size can be controlled by means of the shear gradient during the precipitation or by the use of emulsion stabilizers. Emulsion stabilization leads to particles in the size range 0.5 to 20  mu m with a particularly narrow particle size distribution. Catalysts for polyolefin synthesis can be prepared on the basis of magnesium alkylates prepared by the process according to the invention. The polymer is advantageous with respect to particle habit and particle size distribution, compared with the prior art. A narrower particle size distribution, and thus a reduction in undesired oversize and undersized particles, and a smoother surface structure are achieved.
