  • Patent number: 4115005
    Abstract: A method for measuring a roughness profile of a surface optically is provided. The method essentially comprises projecting through a converging optical system a pair of light rays on a surface to be measured, the light rays being focused slightly before and behind the measuring surface, receiving reflections of the projected light rays by photoelectric means to produce two different electric signals representing the intensity of the reflections of the two light rays, detecting a roughness profile of the surface on the basis of the difference of the two electric signals, and moving the light rays along the measuring surface to obtain a continuous roughness profile of the surface.

  • Patent number: 4107424
    Abstract: A new and useful 1-N-[(S)-.alpha.-hydroxy-.omega.-aminoacyl] derivative of an aminoglycosidic antibiotic, including its deoxy derivative, such as kanamycin B, 3'-deoxyneamine, 3',4'-dideoxyneamine, 3',4'-dideoxyribostamycin or 3',4'-dideoxykanamycin B is now synthetized from the parent substance, aminoglycosidic antiobiotic. The new 1-N-[(S)-.alpha.-hydroxy-.omega.-aminoacyl] derivative shows a wider and/or higher antibacterial activity than the parent substance and is useful in the treatment of infections by gram-negative and gram-positive bacteria, including drug-resistant strains thereof. The preparation of this new derivative may be made by 1-N-acylating the parent aminoglycosidic antibiotic with (S)-.alpha.-hydroxy-.omega.-aminocarboxylic acid with the amino group being protected, and chromatographically separating the acylated products to isolate the desired 1-N-acyl derivative, followed by the removal of the amino-protecting group.

  • Patent number: 4082067
    Abstract: An automatic fuel heating injection valve to be mounted in a combustion chamber of an internal combustion engine. The valve has a fuel evaporating chamber which is communicable with the combustion chamber through a fuel injecting port, a stem valve opening and closing the fuel injecting port, and an actuator which operates the stem valve in response to a pressure prevailing in the combustion chamber. A liquid fuel is sufficiently heated en route to the evaporating chamber by the heat of wall and evaporated through a wick of porous and transudatory material in the evaporating chamber. The evaporated fuel is mixed with combustion gas and fresh air in the evaporating chamber, and the mixture is automatically injected in the combustion chamber.
