Disclosed is a one-component magnetic developer for the electrophotography, which comprises one-component magnetic toner particles and at least one fine particulate additive selected from the group consisting of hydrophobic silica, hydrophilic silica and alumina, wherein the one-component magnetic toner particles have a sphericity degree (DS), defined by the following formula, of 70 to 90%, and a specific surface area of 1.4 to 2.0 m.sup.2 /g:DS=Cc/CT (1)wherein Cc represents the outer circumference of a circle having the same area as the projected area of the toner, and CT represent the actual outer circumference of the projected plane of the toner. This developer is excellent in the flowability and can provide an image having a high density.

The present invention provides an electrophotographic toner containing, as a fixing resin, a styrene-acrylic copolymer in which styrene content, molecular-weight distribution and acid value are specified. The electrophotographic toner of the present invention is improved in heat resistance by raising the glass transition temperature of the fixing resin, while assuring excellent low-temperature fixing properties and resistance to off-set.

摘要:
An image display apparatus is caused to respectively display operation guidance constituted from operation instruction icons and end display icons each presenting a specific image and card type icons having display images indicating specific images in first and second specific regions of an image display screen under a predetermined condition. In the case where the operation instruction icons are selected and one end display icon is thereby reached when the card type icon corresponding to the specific image presented by the one end display icon is displayed in the second specific region, the display image of the card type icon is displayed so as to become an exposed state at least temporarily. A privilege relating to a special effect is applied to the player character in the case where all of the display images of the card type icons keep the exposed states for a predetermined period of time.

A heteropentamer composed of a fusion monomer (32) comprising a fusion protein of an antigenic amino acid sequence and an amino acid sequence of a monomer of a mucous membrane-binding protein and a nonfusion monomer (20) of an amino acid sequence of a monomer of a mucous membrane-binding protein. A homopentamer composed of a fusion monomer including a fusion protein of an antigen derived from an envelope protein of Japanese encephalitis virus and an amino acid sequence of a monomer of a mucous membrane-binding protein. These heteropentamer and the homopentamer can be used as a vaccine.
摘要:
A surface of particles of at least one powder selected from PMMA, nylon, polystyrene, a silicone elastomer powder, benzoguanamine, a styrenedivinylbenzene pinhole polymer, ethylene tetrafluoride, a polyethylene powder, a polyurethane powder, a silk powder, an organic pigment and a composite of at least one of these and a metal oxide and/or a metal hydroxide is treated with a low-molecular organosilicon derivative, with or without a water-soluble cationic polymer to improve the hydrophilicity of the powder. The thus-treated powder is quite excellent in dispersibility (readily dispersible) in an aqueous dispersion medium, especially an aqueous dispersion medium in acidic and alkaline conditions, specifically with pH from 3 to 13 and in dispersion stability. The use of the surface-treated powder provides a dispersion, preferably dispersion for cosmetic, excellent in dispersibility and dispersion stability and the like. The use of the surface-treated powder, or the use of the dispersion provides further a cosmetic excellent in dispersibility and dispersion stability and further in re-dispersibility and dispersion stability with lapse of time when selecting aqueous cosmetic as an agent form.

摘要:
In a video game that progresses a game using a limited number of items, the game can be made more interesting. In an area data table 126-1 of a first area, a brand ‘CAT’ having a previous brand point ‘14%’ is ‘BEST 1’, and a brand ‘BOAR’ having a previous brand point ‘13%’ is ‘BEST 2’. In addition, a brand ‘TIGER’ having a previous brand point ‘3%’ is ‘WORST 2’, and a brand ‘RAT’ having a previous brand point ‘2%’ is ‘WORST 1’. Accordingly, if a player character executes a battle against an enemy character in the first area, when an item of the brand ‘CAT’, which is ‘BEST 1’, is used, its power becomes three times higher than a reference power, and when an item of the brand ‘BOAR’, which is ‘BEST 2’, is used, its power becomes one and half times higher than the reference power. In addition, when an item of the brand ‘TIGER’, which is ‘WORST 2’, is used, its power becomes 0.5 times lower than the reference power, and an item of the brand ‘RAT’, which is ‘WORST 1’, becomes unavailable.
