A gaming device including a plurality of reel sets where at least one of the reel sets includes an inner reel and an outer reel. The other reel sets include a plurality of symbols. Upon the activation of the reel sets, the inner reel displays a plurality of nudge symbols, which each identify a direction of movement of the outer reel. The outer reel includes a plurality of symbols and defines a viewable area. A processor causes the outer reel to indicate one of the symbols or the viewable area. If the viewable area is indicated, the processor moves the outer reel to indicate one of the symbols on the outer reel based on the direction of movement associated with the nudge symbol viewable through the viewable area. The processor provides an outcome to a player based on the symbols indicated on the reel sets.

The present invention relates to a compression device for stimulating the efflux of a body fluid from a body part. The device has a compression unit with a pressure-application region made of a deformable material, the region being formed to generate a repulsive force between the body part and the compression unit. The repulsive force passes through a force maximum then decreases to serve as an indication that the body part is guided sufficiently firmly and far enough onto the compression unit.

The present invention provides a solid catalyst component for the polymerization of olefins, comprising magnesium, titanium, a halogen and an electron donor, wherein said electron donor comprises at least one selected from the group consisting of ester of polyol of the formula (I):R1CO—O—CR3R4—A—CR5R6—O—CO—R2  (I)wherein, R1 and R2 groups, which may be identical or different, can be substituted or unsubstituted hydrocarbyl having 1 to 20 carbon atoms, R3-R6 groups, which may be identical or different, can be selected from the group consisting of hydrogen, halogen or substituted or unsubstituted hydrocarbyl having 1 to 20 carbon atoms, R1-R6 groups optionally contain one or more hetero-atoms replacing carbon, hydrogen atom or the both, said hetero-atom is selected from the group consisting of nitrogen, oxygen, sulfur, silicon, phosphorus and halogen atom, two or more of R3-R6 groups can be linked to form saturated or unsaturated monocyclic or polycyclic ring A is a single bond or bivalent linking group with chain length between two free radicals being 1-10 atoms, wherein said bivalent linking group is selected from the group consisting of aliphatic, alicyclic and aromatic bivalent radicals, and can carry C1-C20 linear or branched substituents one or more of carbon atom and / or hydrogen atom on above-mentioned bivalent linking group and substituents can be replaced by a hetero-atom selected from the group consisting of nitrogen, oxygen, sulfur, silicon, phosphorus, and halogen atom, and two or more said substituents on the linking group as well as above-mentioned R3-R6 groups can be linked to form saturated or unsaturated monocyclic or polycyclic ring.

A method and system for obtaining consumer preferences over a communication network from consumers. The system searches the product database for products or services based on consumer's search criteria. The system displays the products or services and / or advertisements related to the consumer's search criteria in accordance with the ranking parameter(s) specified by the user. The consumer's preferences, i.e., the search criteria and the ranking parameter(s), are stored in the database for future references, e.g., determine consumer trends, etc.

It is made possible that, in accordance with a plurality of radiographing modes such as the still image radiographing mode and the moving image radiographing mode, the outputs both in the irradiation period and in the non-irradiation period are made to fall within the dynamic range of the radiographing system, whereby an accurate, high-S / N-ratio X-ray radiographic image is obtained. For that purpose, in accordance with the plurality of radiographing modes, an arithmetic operation unit adjusts a power source to control voltage to be applied to a reading circuit unit or an Analogue-Digital conversion unit, such that, in each of the radiographing modes, both an electric signal in the X-ray irradiation period and an electric signal in the X-ray non-irradiation period fall within the dynamic ranges of the reading circuit unit and the Analogue-Digital conversion unit.

An optical waveguide having means for performing optical coupling with high efficiency at a predetermined position in an optical circuit substrate and which optionally includes an optical-electrical circuit board. Also provided are an optical waveguide, an optical path thereof being changed in an optical circuit at a steep angle and the optical waveguide for performing coupling and splitting of light being decreased in size in the optical circuit. The optical waveguide has a core and a cladding layer, and a wall surface, which is formed by cutting out at least a part of the core in a thickness direction of the core through irradiation of a laser beam and crosses at least a part of the core, which is a specular surface.
