  • Patent number: 9899617
    Abstract: A production method of a hole blocking layer includes: a liquid layer forming step that causes a liquid composition and a surface of a member on which the hole blocking layer is to be formed, to contact with each other thereby forming a liquid layer comprising the liquid composition on the surface of the member on which the hole blocking layer is to be formed, the liquid composition containing a zinc source comprising bis(acetylacetonato)zinc, a complexing agent comprising acetylacetone, and a polar solvent; and a drying step that heats the liquid layer formed by the liquid layer forming step to vaporize the complexing agent and the polar solvent from the liquid layer thereby forming a hole blocking layer comprising zinc oxide on the surface of the member on which the hole blocking layer is to be formed.

  • Patent number: 9293721
    Abstract: Provided is a hole-blocking layer which has excellent basic characteristics such as high photoelectric conversion efficiency, while exhibiting excellent productivity. The hole-blocking layer is produced by a process that has a step of bringing an aqueous solution containing hydrogen peroxide and titanium (IV) oxysulfate into contact with the surface of a member on which the hole-blocking layer is to be formed, and holding the contact between the aqueous solution and the member at 50 to 120° C., so that an amorphous titanium oxide precursor precipitates on the surface of the member; and a step of drying the amorphous titanium oxide precursor that has precipitated on the member.

  • Patent number: 8367033
    Abstract: In order to isolate and purify an endohedral fullerene, a solvent washing was performed using toluene to concentrate the endohedral fullerene in a residual, but endohedral fullerene could not be efficiently purified because impurities other than the endohedral fullerene could not be sufficiently removed. Thus, the endohedral fullerene is isolated and purified by using a solvent such as chloronaphthalene or tetralin having a high solubility for the endohedral fullerene and concentrating the endohedral fullerene in the solvent. The endohedral fullerene isolated and purified by solvent extraction has a cluster structure where the endohedral fullerene is surrounded with empty fullerenes. Thus, this endohedral fullerene is highly stable and is a useful material applicable to various fields such as medical care and electronics.

  • Patent number: 8047315
    Abstract: In setting of an oil temperature increasing process mode, the drive control technique of the invention starts an engine to actuate a mechanical oil pump that pressure feeds a flow of lubricating oil for lubricating the mechanical parts of a transmission and other relevant parts, actuates an electric oil pump that pressure feeds the flow of lubricating oil, and makes a brake B1 included in the transmission in a semi-engagement state. A motor arranged adjacent to the transmission is then driven with lowered output efficiency. This arrangement effectively accelerates heat generation by the motor and ensures a quick temperature rise of the lubricating oil.

  • Patent number: 7763912
    Abstract: A sensor whose size can be decreased without marring the performance and which can be installed in a narrow place, an electric device, and a method for easily manufacturing the electric device. By vacuum deposition of semiconductor on a columnar body or by applying a melt, solution, or gel of semiconductor to the columnar body, a coating of semiconductor is formed. Four insulating wires, a stripe band of the connected four insulating wires are wound around the columnar body. Then, one of the insulating wires is removed to form a copper wire in the vacant portion by copper vacuum deposition. Lastly, another insulating wire not adjacent to the copper wire is removed to form an aluminum wire in the vacant portion by aluminum vacuum deposition. By measuring the resistance between the copper and aluminum wires, the intensity of light striking the semiconductor can be determined.

  • Patent number: 7755141
    Abstract: Integrated circuits such as semiconductor memories, image sensors, PLA's, and the like have been formed on rigid, planar substrates such as silicon substrates. This has resulted in shapes without flexibility and limited applicabilities. Further, since multiple circuit elements are continuously formed on a flat surface, it has been impossible to produce a non-defective semiconductor memory unless all the circuit elements are fabricated without defects, making it difficult to improve a yield. It is thus devised to weave or braid linear devices into a fabric shape to prepare a planar semiconductor memory, or to bundle up linear devices to prepare a linear semiconductor memory. The integrated circuit comprising the linear devices is flexible and light-weighted, and is thus usable in various applications. It becomes possible to prepare an integrated circuit by once fabricating linear devices and selecting only non-defective ones therefrom, thereby enabling an improved production yield of integrated circuits.
