Abstract: Silicone elastomer spherical particles having a volume mean particle size of 0.1-100 ?m are coated with a polyorganosilsesquioxane and washed with alcohol or a mixture of alcohol and water. The coated fine particles are water repellent so that they are non-dispersible in water and float on water.

These silicone microparticles are capable of absorbing a large amount of the above types of polymethylsiloxanes, which represent low-viscosity silicones, and can therefore suppress the greasiness, stickiness, and oily film feeling of cosmetic materials containing this type of polymethylsiloxane.

Abstract: The invention relates to a pupil filter used for the illumination optical system of a semiconductor aligner or the like that can prevent a decrease in the quantity of light having transmitted through it, enhance the efficiency of semiconductor exposure, reduce loads of correction by the optical proximity effect and yield a stable yet high-resolution optical image without engendering size fluctuations of a pattern imaged on a wafer depending on a mask pattern pitch. Specifically, the invention provides a diffractive optical device for the formation of a pupil filter used for the illumination optical system of an aligner adapted to direct light emanating from a light source to a mask via an illumination optical system and project a pattern on the mask onto an alignment substrate and exposing it to light via a projection optical system. The pupil filter formed by the diffractive optical device is a dipole pupil comprising two light transmissive areas (11).

Abstract: The invention discloses an aqueous slurry of globular particles of a silicone-based composite elastomer consisting of titanium dioxide particles and a crosslinked silicone elastomer as the matrix for the titanium dioxide particles. The aqueous dispersion comprises from 10 to 60% of the globular elastomer particles of 0.1 to 100 &mgr;m diameter, from 0.1 to 30% by weight of a surfactant which is preferably an anionic surfactant such as a salt of a dialkyl sulfosuccinate and the balance of water. The aqueous dispersion of the globular elastomer particles is quite satisfactory as an ultraviolet-shielding adjuvant in water-base cosmetic or toiletry preparations in respect of good stability of dispersion, high ultraviolet-shielding power and surface lubricity.

Abstract: An image display apparatus for displaying a plurality of objects in a space using a simplified and efficient structure. The apparatus includes a first storing section having areas for scanning lines, and for each scanning line, has an area that stores the object numbers of the objects having that scanning line as the display start scanning line for the objects. In addition, other sections store a display end scanning line and an object information set for each of the objects. A display end determining section reads the object numbers of the current scanning line, and reads the display end scanning line for the objects of the read object numbers to determine whether the current scanning line is the display end scanning line for these objects.

Abstract: The invention is directed to an information-recorded medium with easily selectable and identifiable items of information, which is virtually protected against forgery and has enhanced security against some improper use, and a method for reading such a medium. This information-recorded medium 1 includes a substrate 2 and a layer 3 with information recorded thereon by the printing of infrared absorbing ink, said layer 3 being provided on the surface of the layer 2. The printed layer 3 is provided thereon with a relief hologram-recorded layer 7 through an adhesive layer 4, said hologram-recorded layer 7 being built up of a reflecting layer 5 transparent to the infrared region and a relief hologram-formed layer 6 provided on the surface of the reflecting layer 5. For reading, the hologram-recorded layer 7 is reconstructed by visible light, while the printed layer is reconstructed by infrared light, and the medium 1 is identified on the basis of the thus reconstructed information.

Abstract: A hologram which contains the record of a parallel bar-shaped pattern, like a bar code pattern, and which can be read with a single light-receiving element of simple structure with fewer restrictions on the installation position of the light-receiving element and with a minimal lowering in the read accuracy even if the light-receiving element is disposed a little out-of-position. Also disclosed is a method of reading such a hologram. A hologram is recorded in a region that extends in a direction intersecting each bar of a reconstructed bar-shaped pattern and that is not shorter than the length of the reconstructed bar-shaped pattern at least in the above-described direction. Alternatively, the hologram is recorded in a stripe region elongated at the above-described direction.

Abstract: A circuit for detecting an end point of an arc in XY coordinate system comprises a first register storing an X coordinate value of a given end point, a second register storing an Y coordinate value Yse of the same given end point, a third register storing a Y coordinate value Y of a coordinate point of a calculated arc pattern, a fourth register storing a Y coordinate Y of the same coordinate point of the same calculated arc pattern. A first comparator is coupled to the first register and the third register to generate a first coincidence signal when a content of the first register is coincident with a content of the third register and when a tangential angle of the calculated coordinate point is within a first angular extent.

Abstract: An information transfer from a first memory area to a second memory area is performed via a subsidiary memory. The information is read out of the first memory area by an upper portion of a first address designating the first memory area and is written into the subsidiary memory by a lower portion of a second address designating the second memory area. Thereafter, the information written into the subsidiary memory is read out thereof by a lower portion of the first address and is written into the second memory area by an upper portion of the second address. Thus, the information of the first memory area is rotated and transferred to the second memory area without shifting.

Abstract: A system for searching a predetermined boundary of a closed pattern comprises a memory for storing data of a given closed pattern, and a reading unit for sequentially reading each pair of vertically adjacent words of each pair of vertically adjacent lines of the given closed pattern from the memory in the same reading direction. A search unit receives the pair of vertically adjacent words from the reading unit for searching a boundary in each of the pair of vertically adjacent words and for generating data indicative of a position of a found boundary for each of the pair of vertically adjacent words. A comparison unit receives the boundary position data of the each pair of vertically adjacent words so as to judge in which of the vertically adjacent words the boundary is found earlier than the other. A processing unit coupled to the comparison unit determines whether or not the found boundary is the predetermined boundary.

Abstract: A rotated pattern generating system includes at least a X-direction straight line generator adapted to calculate, a difference in X- and Y-directions between the position of a given dot on a destination coordinate and a position of the next dot to be coordinate transformed. The difference is determined by the difference on the source coordinate between the given dot and the next dot to be transformed and a required rotational angle .theta.. The system further comprises a detector connected to the X-direction straight line generator for discriminating whether or not a residual pattern occurs each time the X-direction straight line generator generates an output, and a dot generator responsive to the output of the detector to generate, when a dot lack is discriminated on the position of the residual pattern the same dot information as that of the dot adjacent to the residual pattern position in the destination coordinate.
