摘要:
A flooring system comprising a flooring panel having a panel body, and detachable support legs is disclosed. The panel body has a set of threaded holes having internal threads of a given pitch extending uniformly throughout the hole (the regular threads). One end of the detachable support legs is provided with a threaded section having two types of external threads of the identical pitch to the internal threads; one type is the regular threads and the other type has the crest of each thread wider than the crest of the regular threads, and the wider crest is formed with a slit extending continuously on the tip of each crest (the split threads). At least the leading end the threaded section of the leg is provided with the regular threads. The placement of the regular and split-threads can be reversed on the panel body and on the threaded section of the leg, to achieve the same purpose of providing firm and efficient locking system. Such a flooring system is convenient and cost efficient for the construction of a double-floor structure required in modern automated office buildings.

A paper coating composition is disclosed, which comprises:(A) a pigment, and(B) a copolymer emulsion prepared by polymerizing a monomer mixture containing:(i) 5 to 40 wt % of an .alpha.-olefin of the formula:CH.sub.2 .dbd.CH--R.sub.1 wherein R.sub.1 is a hydrogen atom or an alkyl group having 1 to 12 carbon atoms;(ii) 30 to 90 wt % of a vinyl ester of the formula: ##STR1## wherein R.sub.2, R.sub.3 and R.sub.4 are each a hydrogen atom or an alkyl group having 1 to 18 carbon atoms;(iii) 1 to 30 wt % of at least one unsaturated carboxylic acid ester selected from the group consisting of an acrylic acid ester in which the alkyl moiety thereof has 1 to 18 carbon atoms and a methyacrylic acid or dibasic unsaturated carboxylic acid ester in which the alkyl moiety thereof has 1 to 18 carbon atoms; and(iv) 0.1 to 10 wt % of an unsaturated carboxylic acid. The paper coating composition of the invention provides improved printability and printing quality and is particularly useful for gravure printing.
摘要:
The present invention relates to new compound designated as nanaomycin B represented by general formula: ##STR1## Nanaomycin B is a quinone type and is active on mycoplasma, Gram-positive bacteria and trycophyton. This compound is useful as a medicament for infectious diseases of humans and animals caused by a parasite of trichophyton or mycoplasma etc. The acute toxicity (LD.sub.50, intra-penetrial injection) in mice of this compound is 169 mg/Kg.Nanaomycin B is produced by fermentation in which a nanaomycin-producing strain belonging to the genus Streptomyces is cultured in a medium under aerobic conditions and the accumulated nanaomycin B in the cultured broths is recovered therefrom.

This invention relates to a new compound NA-337 and a process for producing the same by fermentation. NA-337 is positive in Dragendorff's reagent. NA-337 is confirmed to be a new compound having a fat-clearing activity. This compound is produced by fermentation, in which an NA-337-producing strain is cultured aerobically in a medium and the accumulated NA-337 is recovered from the cultured matters.

A fryer is provided which, during a standby for cooking, can keep the temperature of a cooking oil slightly lower than a cooking temperature and, during cooking, can quickly raise the oil temperature to the cooking temperature. The fryer also has capabilities of easily performing a heat exchange operation on the cooking oil, preventing degradation of the cooking oil, securing a good kitchen environment and enhancing a work efficiency. The fryer comprises a fryer tank having oil and water for cleaning the oil stored in two layers one upon the other; and a heater installed in the oil layer; wherein the water in the water layer is drawn out from a water suction opening at a bottom of fryer tank, cleaned by a filtering water tank and then delivered into the fryer tank almost horizontally in an off-centered direction from a water supply opening formed in a lower, side wall of the fryer tank, thus rotating the water in the fryer tank in a swirl. The fryer also has a device for discharging impurities collected in the filtering water tank.

For example, a display element (1) formed by an organic EL element and a control element formed by a MOS transistor (2) are connected in series between a driving line (6) to be driven with a voltage or a current and a ground. A gate of the MOS transistor (2) is connected to a control line (7) through a nonvolatile data holding section such as a ferroelectric capacitor (3), and control data of the MOS transistor (2) can be held in a floating state. As a result, the ON/OFF data of each pixel are held in the floating state, and display data are rewritten to only a pixel to be changed in a display state of ON/OFF or the like and held data are displayed on a pixel which is not changed in the display data. Consequently, it is possible to obtain a nonvolatile display device capable of reducing power consumption and operating with a small battery.
