Abstract: Various implementations of removable custom-shaped orthodontic aligners in combination with a removable custom-shaped orthodontic expander in the context of an orthodontic treatment of the patient, related systems, and computer program products and methods for the design and/or manufacturing of such aligners, and/or such expander are disclosed. In an exemplary implementation, multiple aligners of a series of staged aligners and the expander are configured to provide with each other a snap-in, form-lock interface so that the expander is positioned atop, positioned, and held by the aligner. An expander for the upper jaw may include an integrated bite plane. For example, computer program process steps planning the treatment and designing the aligners in combination with the expander are weighing interproximal reduction (IPR) versus transversal expansion.

Abstract: To provide a method for producing surface-modified metal oxide fine particles, which can produce surface-modified metal oxide fine particles having excellent dispersion stability in dispersion liquids having various compositions; a method for producing improved metal oxide fine particles, suitable as a method for producing metal oxide fine particles to be surface-modified in production of the surface-modified metal oxide fine particles; surface-modified metal oxide fine particles which can be produced by the method for producing surface-modified metal oxide fine particles; and a metal oxide fine particle dispersion liquid including the surface-modified metal oxide fine particles. Surface-modified metal oxide fine particles are produced by a method including coating at least a part of surfaces of metal oxide fine particles with a carboxylic acid compound having a certain structure substituted with an amino group which may be cyclic, and/or carboxylate thereof.

Abstract: A curable composition capable of forming a cured product having high refractive index and excellent bending resistance, a cured product of the curable composition, a cured film made of the cured product, a display panel provided with the cured film, and a method for producing a cured product using the above-mentioned curable composition. The curable composition includes a curable compound and a curing agent. The curable compound contains a curable compound including, as a main skeleton, a fused ring in which three or more rings including an aromatic ring are fused, followed by mixing a metal oxide in which a capping agent is covalently bonded to a surface thereof.

Abstract: A curable composition having satisfactory curability, capable of forming a cured product having satisfactory heat resistance and adhesion to a base material, a cured film made of a cured product of the curable composition, a display panel provided with the cured film, and a method for producing a cured product using the above-mentioned curable composition. The curable composition includes a curable compound and a thermal cationic polymerization initiator, the curable compound contains a cationic polymerizable compound containing, as a main skeleton, a fused ring in which three or more rings including an aromatic ring are fused, and the thermal cationic polymerization initiator contains a quaternary ammonium salt-type compound having a specific structure.

Abstract: A cationically polymerizable curable composition comprising a compound having a vinyloxy group bonded to an aromatic group which is easily cured upon light exposure and/or heating, a cured product of the curable composition, and a method of producing a cured product using the curable composition. In a cationically polymerizable curable composition that includes a compound having a vinyloxy group bonded to an aromatic group, a sulfonium salt having a specific structure is used as a curing agent. A cured product is produced by shaping the curable composition into a predetermined shape, and subjecting the shaped curable composition to light exposure and/or heating.

In a coloring agent dispersion including a coloring agent which contains a pigment and a dispersant, a dispersant containing a silsesquioxane compound of a specific structure is used.

Abstract: A photosensitive resin composition which gives a cured film having high light shielding properties and enables stable curing by baking at low temperature, a cured film obtained by curing the composition, a display device provided with the cured film, and a pattern forming method using the composition. A light shielding film-forming process which does not impart thermal damage to a light-emitting element with respect to a substrate provided with a light-emitting element. In a photosensitive resin composition including a binder resin, a photopolymerizable compound, a photopolymerization initiator, a coloring agent, and a thermosetting compound, a carbon black and/or an inorganic black pigment, and an organic pigment are used in combination as the coloring agent, and a photosensitive resin composition in which T2/T1 is 0.80 or more is used.

Abstract: To provide a point donation system which, upon selecting a project for which a donation is to be granted on the basis of a consensus of members, grants a donation according to the number of points given to the members from a point service provider. A point management unit accumulates the donation points given to members. A candidate project management unit manages multiple kinds of candidate projects for donations. A project determination unit, upon receiving the votes from members regarding the candidate projects, selects one or more projects for which a donation is to be granted in accordance with the voting result. The point management unit performs processing for allocating an amount of donation corresponding to the total points accumulated by all of the members to the selected projects in accordance with the voting result.
