In an electrode substrate 1, the surface of a metal circuit layer 12 is covered and insulated by an insulating layer 14. In a photoelectric conversion element that uses this electrode substrate 1, the metal circuit layer is reliably shielded from an electrolyte solution or the like so that corrosion and leak current thereof is effectively prevented, and the photoelectric conversion efficiency can be improved. The insulating layer 14 is preferably made of a material that contains a glass component, and is particularly preferably formed by printing a paste that contains glass frit. The metal circuit layer 12 is preferably formed using a printing method.

Disclosed is an agent for inhibiting decrease in measured values in immunoassays, which may reduce the influences by interfering substances in a test sample so as to promote the accuracy of the immunoassays, as well as an immunoassay and a reagent for immunoassays using the same, with which the decrease in the measured values due to the interfering substances is reduced. The agent for inhibiting decrease in measured values in immunoassays, caused by interfering substances, is an ionic surfactant having a molecular weight of 1000 to 100,000, the agent being a polymer in which a hydrophobic cyclic monomer(s) having an ionic functional group(s) is(are) polymerized.

First and second electrodes are provided in a chamber. The second electrode includes a first part supplying a first gas to a space between the first electrode and the second electrode, a plurality of second parts supplying a second gas to the space, a first supply path of the first gas connected to the first part, and a second supply path of the second gas connected to the second parts. The second supply path includes a main part with a first inlet of the second gas, and a branch part including a plurality of gas flow paths with a second inlet of the second gas. A number of the second parts are connected to each of the gas flow paths. The main part and the branch part are structured so that the second material gas does not flow into the second parts from the first inlet as a straight flow.
摘要:
A solar cell and photovoltaic power generation apparatus including a transparent electrically conductive film, a semiconductor provided on the transparent electrically conductive film, a conductive film opposing the semiconductor, and an electrolyte solution filled between the semiconductor and the conductive film. Metal ions, such as silver ions, may be dissolved in the electrolyte solution. When light is incident on the cell, the metal ions cause an oxidation-reduction reaction in the electrolyte solution and the cell is charged. When the open-circuit voltage decreases because the amount of incident light drops or light is blocked, the cell discharges to function as a secondary cell.

摘要:
This invention provides a method for differentially and simultaneously quantifying two target analytes via a single assay operation with the use of a single type of reagent in each of the two steps, i.e., the first step and the second step. In this method, the reaction product associated with the first target analyte is detected at an early stage of the second step and the reaction product associated with the second target analyte is then detected.

A temperature-compensated crystal oscillator includes an oscillation circuit including an oscillator, a temperature detector, a voltage variable capacitance element coupled to an oscillation loop of the oscillation circuit, and a temperature compensation circuit. The temperature compensation circuit is configured to apply a compensation voltage to the voltage variable capacitance element to compensate a temperature change in response to temperature data detected by the temperature detector. The temperature compensation circuit has a plurality of correction point data. The respective correction point data is set in advance for each divided temperature zone, selects a first correction point data in a lower temperature zone and a second correction point data in a higher temperature zone, as compared with the detected temperature data, performs an interpolation between the first and second correction point data by a weighted averaged first-order interpolation, and generates the compensation voltage.
