    摘要： A novel and very elegant method is proposed for the preparation of N.sub.1 -(2-tetrahydrofuryl)-5-substituted or -unsubstituted uracil, especially, N.sub.1 -(2-tetrahydrofuryl)-5-fluorouracil, by the reaction of the corresponding 5-substituted uracil compound with 2,3-dihydrofuran. The reaction is performed in the presence of a chlorosilane compound, e.g. dimethyldichlorosilane, and a catalytic amount of an organic amine compound and can proceed very rapidly without disadvantageous side reactions to give the objective compound with high purity in a high yield.

    摘要： A novel and efficient method is proposed for the preparation of isosorbide-5-nitrate which is a promising medicinal compound for several diseases due to disorder in heart. The method comprises direct nitration of isosorbide with a concentrated nitric acid in a specific reaction medium containing an aromatic hydrocarbon solvent, e.g. benzene, in addition to conventional acetic acid and acetic anhydride. After neutralization of the reaction mixture and removal of the dinitrate as a byproduct therefrom, the reaction mixture is admixed with an aqueous solution of sodium hydroxide so that a sodium salt of isosorbide-5-nitrate is precipitated in the form of a hydrate, which is a novel compound not known in the prior art. This hydrate sodium salt is then decomposed with an acid to give the desired isosorbide-5-nitrate in a high yield.

    摘要： A semiconductor integrated circuit system having a function of automatically adjusting an output resistance value with reference to a temperature of an LSI which is operating. When a count value obtained from a counter by counting the output of a timer becomes equal to a predetermined value, a temperature sensor measures temperatures of LSIs. If a temperature fluctuation measured from a previous measured value is greater than a predetermined width, then a control apparatus issues an output resistance value adjustment request signal to output resistance adjustment units of the LSIs. When receiving the output resistance value adjustment request signal, the output resistance value adjustment units stop the signal transmission between the LSIs, adjust output resistance values of output circuits in such a manner that the output resistance values are matched with a characteristic impedance of a transmission line, and maintains the adjusted output resistance values until the output resistance value adjustment units receive next output resistance value adjustment request signal.

    摘要： A semiconductor integrated circuit comprising a clock pulse generator, peripheral function blocks and bus master modules. The peripheral function blocks are commonly supplied with a first system clock signal of a constant frequency generated on the basis of the output from the clock pulse generator. The bus master modules are fed with a second system clock signal generated on the basis of the pulse generator output. The frequency of the second system clock signal is variable and lower than that of the first system clock signal. The function blocks supplied with the first system clock signal are connected to a data bus separate from the one connected to the function blocks fed with the second system clock signal.
