摘要:
The invention provides a display method for displaying an image by deposition of metal fine particles. The display method includes at least depositing metal fine particles, from an electrolytic solution that has at least a metal ion of the metal particles and that is provided between a pair of substrates having at least one translucent substrate, onto a surface of any one of the pair of substrates by imparting one stimulus. A concentration of the metal ion of the metal fine particles in the electrolytic solution after imparting the stimulus is about 200 mmol/l or less. The invention further provides a display device which uses the display method.

摘要:
A water-activated cell comprises an acidic medium including an acidic substance and having a first electrode disposed therein, a basic medium including a basic substance and having a second electrode disposed therein, which basic medium is disposed adjacent to or near the acidic medium, a first reaction substance including a first active material that causes an oxidation reaction at the first electrode, a second reaction substance including a second active material that causes a reduction reaction at the second electrode, and a water-injecting device for injecting water or an aqueous solution into an area where the acidic medium, the basic medium, the first reaction substance, and the second reaction substance exist together, so as to initiate a discharging reaction by the acidic substance, the basic substance, the first active material, and the second active material.
摘要:
The present invention provides a sensor including an acidic medium; a first electrode disposed in the acidic medium; a basic medium adjacent to or close to the acidic medium; a second electrode disposed in the basic medium; and a detector for detecting one of voltage and current that is generated between the first and second electrodes by a first substance which causes a reaction of removing electrons from the first electrode with hydrogen ions contained in the acidic medium, and a second substance which causes a reaction of supplying electrons to the second electrode with hydroxide ions contained in the basic medium, and provides a method of detecting a substance using the sensor.

An audio analysis apparatus includes the following components. A main body includes a discrimination unit and a transmission unit. A strap is used for hanging the main body from a user's neck. A first audio acquisition device is provided to the strap or the main body. A second audio acquisition device is provided to the strap at a position where a distance between the second audio acquisition device and the user's mouth is smaller than the distance between the first audio acquisition device and the user's in a state where the strap is worn around the user's neck. The discrimination unit discriminates whether an acquired sound is an uttered voice of the user or of another person by comparing audio signals of the sound acquired by the first and second audio acquisition devices. The transmission unit transmits information including the discrimination result to an external apparatus.

摘要:
An audio analysis apparatus includes the following components. A strap has an end portion connected to a main body and is used to hang the main body from a user's neck. A first audio acquisition device is at the end portion or in the main body. Second and third audio acquisition devices are at positions separate from the end portion by substantially the same predetermined distances, on the respective sides of the strap extending from the user's neck. An analysis unit discriminates whether an acquired sound is an uttered voice of the user or another person by comparing audio signals of acquired by the first and second or third audio acquisition devices and detects an orientation of the user's face by comparing the audio signals acquired by the second and third audio acquisition devices. A transmission unit transmits the analysis result to an external apparatus.

A light-emitting device includes a light-emitting portion and an oxygen concentration control portion. The light-emitting portion includes a surface. The light-emitting portion emits light with an intensity corresponding to an oxygen concentration on the surface when receiving light energy. The oxygen concentration control portion controls the oxygen concentration on the surface of the light-emitting portion.
