Abstract: Disclosed is novel compound UCT-1003 represented by the following formula: ##STR1## and having anti-tumor activity. UCT-1003 is produced by culturing a microorganism belonging to the genus Paecilomyces.

Abstract: Supplied with an output response signal from a circuit under test in each test channel, a level comparator compares the signal with a reference level which defines a normal logical level. The compared output is applied to two independent signal detectors, wherein it is detected and held at the timing of two strobe pulses which are provided thereto via two different signal lines at a desired time interval. These detected signals are applied to two logical comparators, wherein they are compared with expected value signals, respectively. An expected value signal switching circuit may be provided by which the expected value signal in this test channel and the expected value signal in another test channel are selectively provided to one of the logical comparators. It is also possible to adopt an arrangement in which test results read out of a plurality of storage areas of a failure analysis memory are provided as mask data to a desired one of the logical comparators to thereby mask its logical comparison.

Abstract: The present invention relates to novel compounds DC-92B and DC-92D having anthraquinone moiety and represented by the following planar structural formula (I) and to a process for producing the same. These compounds can be produced by culture of a microorganism belonging to the genus Actinomadura, and are useful as medicaments because of their antibacterial and anti-tumor activities.

Abstract: A compound represented by the formula: ##STR1## wherein R is a hydrogen atom or a lower alkyl group, X is a hydroxymethyl group and Y is a cyano group, and when R is a lower alkyl group, X and Y may combine to form --CH.sub.2 --O--, and salts thereof, process for preparing the same, and an anti-tumor composition containing the same, which is improved in stability in comparison with a starting compound DC-52.

Abstract: New antibiotic compounds, Fortimicin factors KG.sub.1, KG.sub.2 and KG.sub.3 are produced by fermentation of microorganisms belonging to the genus Micromonospora. The antibiotic compounds are accumulated in the culture liquor and are isolated therefrom.

Abstract: Phenazine compounds represented by the formula: ##STR1## wherein R is a hydrogen atom, an unsubstituted or substituted lower alkanoyl group, or an unsubstituted or substituted arylcarbonyl group have antibacterial and anti-tumor activities.Some of these compounds are produced by incubation of a microorganism.

Abstract: The antibacterial compound DC-38-V is produced by culturing a microorganism belonging to the genus Streptomyces.

Abstract: The antibacterial compound DC-38-V is produced by culturing a microorganism belonging to the genus Streptomyces.

Abstract: A double-walled paper container produced by placing a preformed paper container in a shaping die set cavity of a vacuum draw shaping apparatus, positioning a single piece of synthetic resin film or sheet on the top of said paper container, holding the film at the peripheral edge thereof, heating the film to make the plastic film, stretching the film and applying negative pressure to the film to line said preformed paper container with the film is in water-tight fashion and wherein the lined paper container has a good shape holding ability and is hygienic for the user thereof.

Abstract: The process for producing a container cover member by stamping a sheet of material stock to form a plurality of through bores, injection molding a closure member in each through bore and subjecting each through bore to a second stamping to form a handle in a portion of the closure member.

Abstract: A container cover member comprising a cover sheet formed of paper or thermoplastic synthetic resin having an opening of a desired size and shape in a predetermined position and over said opening a closure member having a pull tab or handle formed of thermoplastic resin which is compatible with the material of said cover sheet, said opening being easily uncovered when said pull tab is pulled up, and the process for making the cover member.

Abstract: New antibiotic compounds, Fortimicin factors KG.sub.1, KG.sub.2 and KG.sub.3 are produced by fermentation of microorganisms belonging to the genus Micromonospora. The antibiotic compounds are accumulated in the culture liquor and are isolated therefrom.

Abstract: Thermoplastic multi-walled pipe which has at least two tubular members different in inside diameter and concentrically arranged, these tubular members being spaced and supported by a plurality of ribs so as to provide hollow portions therebetween. The bond strength between the inner end surface of the rib and the tubular member supported thereby is less than that between the outer end surface of the rib and the tubular member supported thereby, so the exposure of the inner tubular member is easily achieved by means of an external force.

Abstract: New antibiotic compounds, Fortimicin factors KF and KG are produced by fermentation of microorganisms belonging to the genus Micromonospora. The antibiotic compounds are accumulated in the culture liquor and are isolated therefrom.
