    摘要： There is disclosed a process for producing acetic acid in which methyl formate is isomerized into acetic acid with a catalyst containing at least one of Pd, Ru and Ir, at least one compound of said metals or a mixture thereof, and a promoter of a halide compound in the presence of carbon monoxide. This process can be carried out under mild reaction conditions and acetic acid is obtained in high yield.

    摘要： An improved memory circuit having a fast write speed is disclosed. A first control signal is generated when a first period of time has elapsed from the initiation of an access cycle, in a fixed timing both in a read operation and a write operation. A second control signal for enabling a data input circuit when a second shorter period has elapsed from the initiation of the access cycle only in a write operation. A data transfer between a selected bit line and a bus line is performed when at least one of the first and second control signals.
