  • Patent number: 11945177
    Abstract: A first laminated body is worked to form a second laminated body, the first laminated body being formed by laminating prepregs including reinforcing fibers and resin, the second laminated body including a flat portion and a wavy portion, the flat portion being located at at least one of side edge portions of the second laminated body, the wavy portion being located at a portion adjacent to the side edge portion and extending along a longitudinal direction. An intermediate product is formed from the second laminated body by a forming die such that the flat portion becomes a bent portion that is an inside portion whose circumferential length is shorter in a curved portion, and the wavy portion becomes a bent portion that is an outside portion whose circumferential length is longer in the curved portion.

  • Patent number: 8038861
    Abstract: A laminated gas sensor element extending in a longitudinal direction and having a detection part including a plate-shaped element body which has a heater layer having an embedded resistance heating body and a detection layer laminated to the heater layer and having a vertical surface along a lamination direction and a horizontal surface perpendicular to the lamination direction; and a porous protective layer coating the vertical surface and the horizontal surface of the element body constituting the detection part, wherein a thickness of the protective layer formed on the vertical surface is thicker than a thickness of the protective layer formed on the horizontal surface.

  • Patent number: 4607114
    Abstract: This invention relates to a novel platinum-diamine complexes represented by the general formula: ##STR1## wherein R.sub.1 and R.sub.2 each represents a lower alkyl group having 1 to 3 carbon atoms or jointly represent an alkylene group having 3 to 6 carbon atoms; two X's each represents a halogen atom, ##STR2## or jointly represent a group represented by ##STR3## in which R.sub.3 is a lower alkyl group or a group represented by --OM (wherein M is an atom which can become a monovalent cation); Y is --OH or a halogen atom; and n is 0 or 1, and n is 1 when R.sub.1 and R.sub.2 jointly represent an alkylene group having 5 carbon atoms and X is chlorine. The platinum-diamine complex of this invention has an excellent antitumor activity and a lower renal toxicity than cis-Platin now widely used as a carcinostatic as clinical medicine, and is expected as a carcinostatic lowered in toxicity.

  • Patent number: RE30451
    Abstract: A novel process for producing antibiotics bleomycins by innoculating and aerobically culturing in a nutrient source-containing medium a bleomycin-producing strain belonging to the actinomyces, wherein the culture is effected in the presence of an amino compound having at least one ##STR1## group and at least one basic group selected from amino, imino, guanidino, amidino and sulfonium groups and nitrogen-containing cyclic compounds, or in the presence of a compound convertible in the culture liquor to such amino compound as mentioned above, thereby selectively producing a known or novel bleomycin component corresponding to the said amino compound or to an amino compound derived from the above-mentioned compound, and then the known or novel bleomycin is recovered by known means from the culture medium.
