摘要:
High yields of L-glutamic acid are produced by culturing mutant strains of microorganisms of the genera Pseudomonas and Protaminobacter in a culture medium containing methanol as the principal source of assimilable carbon. L-glutamic acid is accumulated in the culture liquor and is isolated therefrom.

摘要:
The present invention is a system for filling a container main body at least whose drum body is made of a flexible film, with a viscous material. A viscous material is charged by the charging means into container main bodies conveyed by the container conveying means, the drum body of the container main body is pressed by the pressing means to cause the surface of the viscous material to bulge, and the opening of the reinforcing component of the container main body is capped by the capping means, allowing the opening to be capped in an air-tight manner with a lid member while virtually all of the air inside the container main body is evacuated, and preventing air from being left over in the container main body so as to prevent hardening, curing and deterioration in the quality of the viscous material that can be caused by such remaining air.
摘要:
A fence and a furring strip for fence, which are light in weight and strong and are resistant to snow and wind are provided. Bent wire rods 1 are bent in a triangle shape, at the top 10 of which, at the portion a little off-center, a pair of parallel wire rods 2 are mounted both on the front and the rear sides. The furring strip in such a construction is inserted between vertical wire rods 51, 51 of the fence body formed like a folding screen. The furring strip is fixed on the fence body by an appropriate fitting and forms a fence.

摘要:
A flame retardant comprising a mixture of 10 to 90% by weight of powder A and 90 to 10% by weight of powder B of magnesium hydroxide, the powder A containing 40 to 70% by weight of a powdered double salt of magnesium carbonate and calcium carbonate and 60 to 30% by weight of powdered basic magnesium carbonate; and a flame-retardant resin composition comprising 100 parts by weight of a thermoplastic resin and 30 to 300 parts by weight of the flame retardant. Preferably, the double salt is huntite, and the basic magnesium carbonate consists essentially of hydromagnesite. It is preferred to treat the flame retardant, in the form of a powder mixture, with a surface treatment agent. The flame-retardant resin composition is adapted for use as a sheath or insulation for an electric wire or cable, a fire-arresting material, or a wall material.
摘要:
The multi-position electrical switch includes a printed circuit (PC) board arranged in a casing and supporting an array of stationary contacts encircling a light emitting element fixed on the PC board. A resilient rubber sheet covers the PC board and supports an array of movable contacts arranged opposite the stationary contacts. A control knob having a central opening rests on the rubber sheet in the region of the movable contacts. The bottom of the knob is formed with a tubular projection communicating with the central opening of the knob and extending to the level of an opening in the rubber sheet around the light emitting element. The bottom of the knob is provided with four pin-shaped stoppers which delimit the tilting movement of the knob in four directions and the pressing surface portions of the bottom are inclined such as to evenly engage a depressed region of the rubber sheet when the knob is tilted in one of the four directions and the corresponding movable contacts are lowered and pressed against the opposite stationary contacts. The annular end face of the tubular projection has four inclined sections oriented according to the four tilting directions. In a tilted position of the knob, a corresponding inclined section fully engages the flat surface of the PC board thus safeguarding the actuation of the selected contacts only.
