According to the process of the present invention, there can be provided high-quality, high-purity trimellitic acid with extremely small amounts of by-products such as an intermediate of oxidation, an addition compound, and an organobromine compound in high yield. In addition, the residual ratio of bromine used as a catalyst is high, and hence a production cost is curtailed.

摘要： The process for producing a (fluoroalkyl)benzene derivative according to the present invention comprises a step of reducing the total content of group 3 to group 12 transition metals in an alkylbenzene derivative to 500 ppm or less in terms of metal atoms; a step of halogenating the branched alkyl group of the purified alkylbenzene derivative by a photohalogenation to obtain a (haloalkyl)benzene derivative; and a step of subjecting the (haloalkyl)benzene derivative to a halogen-fluorine exchange using HF in an amount of 10 mol or higher per one mole of the (haloalkyl)benzene derivative. The (fluoroalkyl)benzene derivative produced by the process is reduced in the content of impurities such as residual halogens and residual metals, and is useful as intermediates for functional chemical products for use in applications such as medicines and electronic materials.

摘要： A method of detecting a deteriorated condition of a wide range air-fuel ratio sensor is provided. Firstly, a current is applied to an electromotive force cell to detect a voltage Vs0 across electrodes on opposite side surfaces of the cell. Application of the current is suspended, and a voltage drop Vsd1 across the electrodes is detected after lapse of a time ranging from 10 .mu.s to 1 ms after the application of the current is suspended. Based on the voltage drop Vsd1 is detected a first resistance value Rvs1 equated to the temperature of the electromotive force cell. Further, after lapse of a time ranging from 10 ms to 50 ms after the application of the current to the electromotive force cell is suspended, a voltage drop Vsd2 across the electrodes of the electromotive force cell is detected. Based on the voltage drop Vsd2 is detected a second resistance value Rvs2 equated to an internal resistance of the electromotive force cell including a resistance component resulting from deterioration. By comparison of the resistance values Rvs1 and Rvs2, the deteriorated condition of the wide range air-fuel ratio is detected. An apparatus for carrying out such a method is also provided.

摘要： A photoelectric conversion apparatus includes a pair of opposite electrodes, and an amorphous silicon film. The amorphous silicon film is sandwiched between the pair of opposite electrodes and serves to perform photoelectric conversion of light including light from a target object. At least one of the pair of opposite electrodes is divided into a set of pattern electrodes respectively connected to the amorphous silicon film in electrically positive and negative directions so as to form a spatial filter electrode. The respective pattern electrodes respectively connected in the positive and negative directions are irregularly arranged on the amorphous silicon film.

摘要： A precision filter for accomplishing filtering of precision of submicron order. A filter element of the filter consists of a plurality of superposed disc-shaped annular support members for filter membranes. Each support member has a radially outwardly extending intermediate section located between an annular boss section and an outer frame section. The intermediate section is formed on its upper and lower sides with a plurality of gently winding elongate ridges and largely winding elongate ridges. Each largely winding elongate ridge extends from the boss section to the outer frame section, but each gently winding elongate ridge located between the two largely winding elongate ridges is separate from the boss section thereby to form two elongate winding grooves which are joined and continuous to a central opening of the boss section. The thus formed support member intermediate section is sealingly covered with the filter membrane so that filtrate flows along the elongate winding grooves to reach the boss section central opening.
