  • Publication number: 20120238759
    Abstract: A method for manufacturing a 6-substituted 1-methyl-1H-benzimidazole derivative represented by the formula (IV) wherein R3 represents a hydrogen atom or a C1-C4 alkyl group. A 4-substituted N2-methylbenzene-1,2-diamine derivative is prepared from a particular 5-substituted N-methyl-2-nitroaniline derivative, subsequently reacting the resulting compound with {4-[(2,4-dioxo-1,3-thiazolidin-5-yl)methyl]phenoxy}acetic acid or an acid chloride or a mixed acid anhydride thereof, and subsequently subjecting the resulting compound to intramolecular dehydration condensation. A compound of the formula (II) wherein R1 represents a hydrogen atom, a C1-C4 alkyl group, or a protective group for the nitrogen atom, and R2 represents a hydrogen atom or a protective group for the nitrogen atom is prepared and used as an intermediate.

  • Patent number: 6895826
    Abstract: The Coriolis mass flow meter of this invention comprises two parallel curved flow tubes 1 and 2, a drive unit 15, and a pair of vibration sensors 16 and 17. An inlet-side manifold 24 dividing the flow of a fluid being measured into the two flow tubes 1 and 2 from the inlet thereof, and an outlet-side manifold 25 joining the fluid flows flowing in the two flow tubes 1 and 2 to discharge from the fluid outlet thereof are mechanically connected to a meter body 30 only at the inlet side of the inlet-side manifold 24 and at the outlet side of the outlet-side manifold 25, respectively. With this arrangement, the effects of vibration transmitted from the meter body 30 and all structures connected thereto can be reduced at the joint parts between the inlet-side and outlet-side manifolds 24 and 25 that serve as vibration fulcrums.
