摘要:
An absorption promoter is disclosed which interacts with hydrophobic amino acid residues of polypeptide derivative medications and substantially increases the absorption of that medication administered orally or rectally. The promoter and medication can be compounded into unit dosages in capsule, tablet, or suppository form, or combined into elixir solutions, suspensions, etc. The absorption promoters are phenylalanine derivatives which may be prepared through conventional N-acylation techniques.

摘要:
A color toner providing a toner image excellent in brightness, clearness and graininess and a process for producing the same are disclosed, wherein a proportion of dispersed pigment particles having a circle-equivalent diameter of 0.3 .mu.m or greater does not exceed 0.1% of the total number of said dispersed pigment particles. The process comprises kneading a water-containing pigment paste and a binder resin at a temperature of 100.degree. C. or higher under pressure in a heat and pressure kneader to remove a water content to obtain a pigment dispersion, melt-kneading the resulting pigment dispersion together with a binder resin, and grinding the mixture.
摘要:
A vibration absorber which comprises a damper provided between the flyweights and the shifter of a centrifugal governor for absorbing or lessening axial and/or radial vibrations produced in the flyweights. The absorber has a very simple construction, of which manufacture, mounting and maintenance can be carried out with facility. Also, it is free from resonance of the damper and its neighboring parts.
摘要:
A holding and sealing material for a catalytic converter for disposition between a cylindrical catalyst carrier and a metal shell covering the outer periphery of the catalyst carrier. The holding and sealing material includes a fiber aggregate mainly formed of alumina-silica based ceramic fibers having a mullite crystal content of 10 wt % or less, and the fiber aggregate is subjected to a needle punch treatment. Owing to the improved holding and sealing material, a catalytic converter having excellent durability and assemblage and having extremely low pollution characteristics is provided.
摘要:
The invention provides a muffler for an internal combustion engine having excellent durability (resistance to scattering) even when being exposed to a high-temperature exhaust gas and capable of maintaining a high sound absorption coefficient over a long period. Such a muffler comprises a metal tube provided with a plurality of small holes, an inorganic fiber sound-absorbing material arranged on the outer periphery thereof and a metal shell covering the outside of the sound-absorbing material, in which a scattering prevention member is disposed between the metal tube and the sound-absorbing material. The sound-absorbing material is a laminated structure of crystalline alumna fiber mat and glass fiber mat. As the scattering prevention member, there is used a stainless woven wire cloth, a woven fabric made from inorganic fiber and a metal roll.
