Abstract: A disc-like grinding wheel 5 is formed with a circumferential groove 5a, the opposite walls of which define grinding surfaces 5b. A rotated carrier 3 brings a load pin 55 into rotary movement relative to the grinding wheel 5 rotated about an axis 5z, so as to pass the load pin 55 through space between the grinding surfaces 5b, whereby opposite end faces 55a of the load pin 55 are ground simultaneously. Thus, time taken by a grinding process may be reduced as compared with a conventional method wherein one end face is ground at a time.

Abstract: A mixture containing hydrogen iodide and water and having a water content of not more than 5% by weight (particularly not more than 3% by weight) in a distillation system is distilled to prevent condensation of hydrogen iodide in the distillation system. The mixture may comprise hydrogen iodide, water, methanol, methyl iodide, acetic acid, and methyl acetate. Even when the mixture contains hydrogen iodide at a concentration of 1 to 3000 ppm on the basis of weight, an acetic acid product having a concentration of hydrogen iodide of not more than 50 ppm can be obtained by withdrawing a fraction containing hydrogen iodide from the top of the column, and withdrawing acetic acid as a side-cut stream or a stream from the bottom of the column. Such a process (distillation process) effectively inhibits condensation of hydrogen iodide in the distillation system and corrosion in the distillation system.

Abstract: An organic EL element that is an electroluminescence element has at least an organic layer held between a pair of electrodes. At least an electrode made of material having a higher volume resistivity, of the pair of electrodes, is formed in a flat form. The organic layer is provided with a plurality of non-light emitting portions. The non-light emitting portions are provided so that a larger number of non-light emitting portions exist per unit area at a position physically closer to the position of a terminal portion at which the electrode made of material having the higher volume resistivity is connected to an external connection terminal. As a result, the level of current passing per unit area is substantially uniform at each position on the element.

Abstract: A method produces acetic acid by continuously reacting methanol with carbon monoxide in the presence of a rhodium catalyst, an iodide salt, methyl iodide, methyl acetate, and water; and thereby producing acetic acid at a production rate of 11 mol/L·hr or more while keeping the acetaldehyde content of a reaction mixture to 500 ppm or less, in which the reaction is carried out at a carbon monoxide partial pressure in a gaseous phase of a reactor of 1.05 MPa or more and/or at a methyl acetate content of the reaction mixture of 2 percent by weight or more to thereby keep the production rate of acetaldehyde to 1/1500 or less that of acetic acid. This method can reduce production of by-products without reducing the reaction rate of acetic acid even at a low water content and a low hydrogen partial pressure in a reaction system.
