SOLUTION: The PDP and the method of manufacturing the PDP are obtained. The PDP includes a front substrate 11 having a discharge-maintaining electrode 12 and a dielectric film 14 formed on the inside of the front substrate 11, and a rear substrate 21 joined against the inside of the front substrate 11 in such a manner that a discharge space 4 is formed between them. The method includes steps of: forming, on the front substrate 11, a paste produced by dispersing particles such as oxide, fluoride, or a compound of oxide with fluoride in a colloidal manner, as a first dielectric film 14 which coats the discharge-maintaining electrode 12 on the front substrate 11; and firing the particles at 300 to 600°C.

PROBLEM TO BE SOLVED: To provide a resistance change type nonvolatile memory which can obtain good electric characteristics even when a silicon substrate is used since reaction, etc. between a resistance change material and the substrate or a metal electrode can be prevented from occurring, and also to provide its manufacturing method. SOLUTION: The resistance change type nonvolatile memory has such a structure that a metal electrode 13 formed of Pt or the like is formed on the substrate 11 such as a silicon substrate via an adhesion layer 12, and the resistance change layer 15 is formed on the metal electrode 13 via a conductive oxide layer 14, and then a metal electrode 16 formed of Au or the like is formed on the resistance change layer 15. For a material of the resistance change layer 15, SrTiO 3 or SrZrO 3 doped with, for example, Cr of 0.01-10 mol% is used, and for a material of the conductive oxide layer 14, La-doped SrTiO 3 or the like is used. The conductive oxide layer 14 and the resistance change layer 15 are formed by metal organic decomposition. COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a crystalline ultrafine particle, which is excellent in dispersibility for compounding it with other materials and has high luminous efficiency and also can be used for manufacturing a transparent stress luminescent material, and a method for manufacturing the same. SOLUTION: The particle diameter of the crystalline ultrafine particle, which illuminates depending on the changing rate of stress with time, is adjusted to at least 5 nm and not more than 100 nm and the particle is compounded with other materials, e.g. a resin. The crystalline ultrafine particle is prepared by using a reversed micelle, i.e. an aggregate of surfactant molecules whose hydrophilic parts are faced inward and the hydrophobic parts outward in a nonpolar solvent, containing water in which is dissolved ions of a metal as the constituent of the crystalline ultrafine particle, or using a reversed micelle including a precursor ultrafine particle which is contained in the water of the reversed micelle. An artificial luminous hair structure, an artificial luminous skin, an artificial luminous body and an artificial luminous cloth, or the like, are produced by using the above composite materials.

PROBLEM TO BE SOLVED: To provide an actuator using an intercalation substance that becomes a new mechanochemical system, and a driving method and system therefor. SOLUTION: This actuator is structured by using the intercalation substance, and the driving system is structured by the actuator and the solution supply system. A host substance of the intercalation substance includes at least one kind of an inorganic or organic layer substance, and a guest substance is ions or molecules existing in a solvent. The guest substance accompanied with the molecules of the solvent is put in/taken out between layers of the host substance, thereby generating displacement.

PROBLEM TO BE SOLVED: To provide a photoelectric element which has a high mechanical strength and a highly stable photoelectric conversion characteristic, can obtain high photovoltaic power, can easily realize a linear three-dimensional structure, etc., and uses Cu2O and a rectifying element which has a high mechanical strength and a highly stable rectifying characteristic. SOLUTION: A planar photoelectric conversion element is constituted by respectively forming thin metallic films 3a and 3b as second electrodes on Cu2O layers 2a and 2b after the layers 2a and 2b are formed on both main surfaces of a Cu plate 1, which is used as a first electrode, by partial oxidation. Alternatively, a linear photoelectric conversion element is constituted by forming a thin metallic film on the outer peripheral surface of a Cu2O layer as a second electrode after the Cu2O layer is formed on the outer peripheral surface of a Cu wire, which is used as a first electrode, by partial oxidization. The thin metallic film is formed by using a metal, such as Cr, etc., having a high melting point. At the time of oxidizing the Cu plate 1 or Cu wire, the atmosphere is maintained in an inert gas or vacuum atmosphere while the temperature is raised from 300 deg.C to 750 deg.C or lowered from 750 deg.C to 300 deg.C.

PROBLEM TO BE SOLVED: To provide a heat transport device capable of efficiently performing heat transport. SOLUTION: The heat transport device includes a working fluid, an evaporation portion, a condensation portion, and a flow path portion. The heat transport device further includes a region provided on at least one of the evaporation portion, the condensation portion and the flow path portion and made of a carbon material. The working fluid is constituted by adding an organic compound having a hydroxyl group to pure water. The evaporation portion causes the working fluid to evaporate from a liquid phase to a gas phase. The condensation portion is communicated with the evaporation portion, and causes the working fluid to condense from the gas phase to the liquid phase. The flow path portion causes the working fluid condensed in the condensation portion to the liquid phase to flow to the evaporation portion. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a light-emitting device which can use power for driving the device itself to diffuse the heat of a light-emitting part effectively, an electronic instrument loading this, and a method for manufacturing the light-emitting device. SOLUTION: The light-emitting device 1 comprises: an EL (Electro-Luminescence) layer 6 which has a first conductive type first semiconductor layer 5 which is of either an n type or a p type, a second conductive type second semiconductor layer 3 opposite to the first conductive type, and an active layer 4 formed between the two layers concerned; and a first conductive type heat-dissipating layer 2 jointed to a side close to the second semiconductor layer 3 of an EL layer 6. In the heat-dissipating layer 2, since heat transportation by heat conduction and a Peltier effect is generated in a direction of leaving from the active layer 4, it is possible to dissipate the heat effectively. Thus, damage caused by the heat of the active layer 4 is suppressed, thus contributing to high brightness and a high output of the light-emitting device 1. COPYRIGHT: (C)2009,JPO&INPIT
