Abstract: The present invention provides an odor-modulating agent that modulates malodors generated in daily living environments or industries to different odors so that harm caused by the malodors can be easily solved, and an odor-modulating method. Specifically, the present invention provides an odor-modulating agent comprising at least one oxygen-containing cyclic compound selected from the group consisting of furan compounds, pyran compounds, and cyclopentanone derivatives.

Abstract: A method includes generating first virtual space data for defining a first virtual space. The first virtual space includes a first avatar associated with a first user terminal; and a first virtual room including the first avatar and a first virtual screen. The method includes detecting a movement of a head mounted device (HMD) included in the first user terminal. The method includes identifying a visual field in accordance with the detected movement of the HMD. The method includes displaying, on the HMD, a visual-field image corresponding to the visual field. The method includes receiving, from a second user terminal, a visiting request signal requesting that a second avatar associated with the second user terminal visit the first virtual room. The method includes updating the first virtual space data by updating a size of the first virtual screen based on a number of avatars arranged in the first virtual room.

Abstract: An electroless gold plating solution with which one or more openings formed in a resist overlying a substrate can be filled in a short time, the openings having a width on the order of micrometer, in particular, 100 ?m or smaller, in terms of the width of the exposed substrate area, and having a height of 3 ?m or larger. The electroless gold plating solution contains a deposition accelerator for deposition in fine areas, and a microfine pattern of 100 ?m or finer is formed therefrom.

Abstract: Disclosed is a microcrystalline-to-amorphous gold alloy-plated film having excellent electrical properties and excellent mechanical properties. Physical properties including both the advantageous properties of a crystalline structure and the advantageous properties of an amorphous structure can be obtained by allowing a microcrystalline phase and an amorphous phase to exist in a mixed state at a specific ratio. The average particle diameter of the microcrystals is 30 nm or smaller, the volume fraction of the microcrystals is 10 to 90%, the knoop hardness is Hk 180 or more, the specific resistivity is 200 ??-cm or less. In the film, hardness and abrasion resistance can be improved while maintaining a good specific resistivity value and chemical stability both inherent to gold at practically insignificant levels. Therefore, the film is useful as a material for connecting an electric or electronic component such as a connector and a relay.

Abstract: An electroless gold plating solution is provided that contains no cyanide compound as a source of gold and that contains a decomposition inhibitor represented by general formula (1), provided that, in a case in which the solution contains a gold complex of sulfite and the decomposition inhibitor is cytosine, the pH 6.0 or less is excluded. In the formula, R1 to R4 denote hydrogen atom(s), alkyl group(s) having 1 to 10 carbon atom(s), which may have substituent(s), aryl group(s) having 6 to 10 carbon atoms, which may have substituent(s), alkoxy group(s) having 1 to 10 carbon atom(s), which may have substituent(s), amino group(s) (—NH2), hydroxyl group(s) (—OH), ?O, or halogen atom(s), R2 and R3 or R3 and R4 may crosslink with each other and form a saturated or unsaturated ring and the saturated or unsaturated ring may include oxygen, sulfur or nitrogen atom(s), each of the above-mentioned substituents may be a halogen atom or a cyano group, and may be a single bond or a double bond.

Abstract: An electroless gold plating solution is provided in which an amount of gold deposited by a displacement reaction is at least 15 ?g/cm2, and the electroless gold plating solution includes a reducing agent that is oxidized by gold, and a reducing agent that is of the same type as or is a different type from the above reducing agent and is oxidized by a substrate metal. The solution can form a uniform gold coating having good adhesion and low porosity in one step.
