| 20100164224 | SEPARATION PREVENTION DEVICE FOR PIPE JOINT - A separation prevention device for a pipe joint has disengagement prevention members and a press member. The disengagement prevention members are disposed at a plurality of locations in a circumferential direction of the pipe, on an inner peripheral surface of an engaging tool or of a receiving opening itself and which are formed with claws. The press member presses the disengagement prevention member radially inward of the pipe and which engages the claw with the outer peripheral surface of an inserting opening. The claw of the disengagement prevention member and the claw of the disengagement prevention member which is adjacent to the former disengagement prevention member in the circumferential direction of the pipe are arranged so as to overlap on each other in the axial direction of the pipe in a state where the claws are engaged with the outer peripheral surface of the inserting opening. | 07-01-2010 |

| 20090294305 | Method for Specifically Detecting Analyte Using Photocurrent, and Electrode, Measuring Cell and Measuring Device for Use Therein - A method, an electrode, a measuring cell, and a measuring device are disclosed which can detect and quantitatively determine an analyte having specific bonding properties, in a highly sensitive, simple and accurate manner using photocurrent. This method comprises contacting a working electrode and a counter electrode with an electrolyte medium, wherein the working electrode has an analyte immobilized thereon through a probe substance and wherein the analyte is bonded to a sensitizing dye; irradiating the working electrode with light to photoexcite the sensitizing dye; and detecting photocurrent flowing between the working electrode and the counter electrode, wherein the photocurrent is generated by transfer of electrons from the photoexcited sensitizing dye to the working electrode. The working electrode comprises an electron accepting layer comprising an electron accepting substance capable of accepting electrons released from the sensitizing dye in response to photoexcitation, wherein the probe substance is supported on a surface of the electron accepting layer. The electron accepting substance is an oxide semiconductor having an energy level lower than that of a lowest unoccupied molecular orbit (LUMO) of the sensitizing dye. The electrolyte medium comprises an electrolyte and at least one solvent selected from an aprotic solvent and a protic solvent, wherein the electrolyte comprises a salt capable of providing an oxidized sensitizing dye with electrons. | 12-03-2009 |
