PURPOSE:The titled composition capable of controlling sufficiently elusion properties of drug independently of acidity (pH) of site of organism, obtained by blending a drug with a chitosan and a carboxyvinyl polymer. CONSTITUTION:A drug is blended with a chitosan shown by the formula I and/or chitosan shown by the formula II and a carboxyvinyl polymer. Any drug can be used as the drug so long as i...

What is disclosed are aqueous emulsions which are formed by the use of certain organofunctional cationic silanes. The emulsions are stable and are formed using reactive silanes that allow the transfer of water immiscible liquids and the silanes to certain substrates with the avoidance of any subsequent re-wetting or re-solubilizing of the silane or water immiscible liquid, and subsequent loss from...

PURPOSE:To stabilize fitting and alignment of a plug by constituting the plug with a metallic collar and a capillary consisting of plural metallic sheets having minute holes. CONSTITUTION:With respect to a capillary 12, plural metallic sheets 14 which have minute holes 13 slightly about 0.001mm larger than about 0.125mm diameter of an optical fiber strand in centers are inserted and stuck to a fro...

Fully cured thermoset ethylene-propylene rubber sheets having integral thermoplastic adhesive strips molded along the lateral edges are produced using a manufacturing method where the strips are applied prior to vulcanization of the rubber sheeting. The factory applied adhesive strip is non-tacky and dry but is activated by heat to securely bond the ethylene-propylene rubber sheets together in an ...

PURPOSE:To prevent contamination and damage of a semiconductor substrate by automatically washing and drying it with means of feeding, thrusting, turning, receiving and conveying. CONSTITUTION:A cassette 2 housing a substrate 1 is moved on a conveyor 32 in a water tank 34 and positioned with a knob after rinsing. The groove 3 of the cassette aligns a V grooves on guides 12 and 13 and when thrusted...

PURPOSE:To enable uniform melt-recrystallization with no defects over the whole wafer, by a method wherein a recess is formed in the wafer support of a heater section so as to be almost coincident with the wafer warp. CONSTITUTION:This susceptor consists of the susceptor bottom 11 having a projection 10 coming into the highest temperature in high frequency impressing and two heat shield plates 12 ...

The absorption of a therapeutically active protein (I) in the blood is improved by intramuscular injection of (I) together with an absorption enhancing agent (II). Particularly, the method is used where (I) has a short in vivo half-life and allows an effective concn. to be maintained for at least 30 min. Also new are packages contg. (I) and (II).

A process for preparing dimethylcarbonate by reacting methanol with mixtures of carbon monoxide and oxygen which also contain hydrogen. The catalyst is constituted by a salt of a metal of groups IB, IIB or VIII of the periodic system, dissolved or dispersed in the reaction medium. It has been found that the hydrogen does not interfere in the reaction, so that a hydrogen-enriched gaseous mixture (s...

A folding knife comprising a handle and a knife blade rotatable about a pivot. The invention is characterized by the combination that the handle (2) consists of only one wood piece, which is sawn open along a central longitudinal plane, so that a longitudinal gap (5) is formed along the greater part, but not along the entire length of the handle (2), that the blade pivot is located at the end (7) ...

A sour gaseous stream comprising H2S is contacted in column 2 with an aqueous reactant solution comprising an effective amount of Fe(III) chelate of an organic acid to obtain a sweet gaseous stream and a mixture including solid sulphur and Fe(II) chelate of the acid. Degradation of the iron chelate in the reactant solution employed in the cyclic processes for H2S removal from sour gaseous streams ...
