摘要:
A pharmaceutical composition comprising a benzoyl urea compound having the formula: wherein X is a halogen atom or a nitro group, each of Y and Z 2 is a hydrogen atom or a halogen atom, Z, is a halogen atom or a trifluoromethyl group, and A is a =CH- group or a nitrogen atom, and at least one member selected from the group consisting of a cyclodextrin, a polyethylene glycol and a refined oil.
摘要:
A system for loading sheet material (2) on to a rotary drum (1) comprises a carrier (4) for carrying the sheet material (2) towards the drum. Means are provided for catching the leading end of the sheet material (2a) and retaining it on the drum and a presser member (52) presses the sheet material on to the drum as the drum rotates. Thus the material is wound on to the drum tightly. The system incorporates a dampening arrangement (51) for dampening the undersurface of the sheet material and/or the surface of the drum so that a good contact is established between the sheet material and the peripheral surface of the drum.
摘要:
An apparatus for producing an electrophotographic print on a photo-sensitive sheet (2) movable through a plurality of predetermined stations so as to produce an electrostatic latent image on the photosensitive sheet, the apparatus including a rotary drum (I) having a peripheral surface defining an image forming section (E) and a non-image forming section (F), the photosensitive sheet being placeable on the image forming section of the drum surface; a developing unit (3) having at least one developing section (30) for supplying a developer to the photosensitive sheet on the drum, thereby making the electrostatic latent image visible; and means (18) for collecting the used developer from the photosensitive sheet, the means being provided axially of the drum in the non-image forming section of the peripheral surface.
摘要:
This invention relates to a novel chartreusin derivative of the general formula (I): and a salt thereof. This chartreusin derivative and a salt thereof have an excellent antitumor activity, which is exhibited even when the site of cancer inoculation and the site of drug administration are different. This invention further relates to a antitumorous composition containing the above-mentioned compound as active ingredient. This invention furthermore relates to a process for producing the above-mentioned chartreusin derivative or salt thereof.
摘要:
A process for producing 2,4-dichlorobenzotrifluoride, which comprises reacting m-dichlorobenzene with a halogenated methane of the formula CF x Cl 4-x where x is 0, 1 or 2, and hydrogen fluoride at a temperature of from 80 to 180°C in the presence of a catalyst of at least one member selected from the group consisting of fluorides of antimony, boron, titanium, tantalum and niobium.
摘要:
A chloronicotinic acid compound is prepared by hydrolyzing a 3-trichloromethyl pyridine compound in the presence of sulfuric acid or phosphoric acid. By this process, a highly pure chloronicotinic acid compound is obtainable in good yield. This compound is useful as an intermediate for medicines.
