Abstract: PURPOSE: A chip filtering method for cutting oil and a filtering device thereof are provided to prevent the damage of a filtering fabric and to reduce a maintenance cost by first filtering large particles of chips using a magnetic body and secondly filtering fine chips or non-metal chips using the filtering fabric and by automatically cleansing the filtering fabric when large amount of chips or sludge are attached to the filtering fabric. CONSTITUTION: To filter the chips of cutting coil, cutting oil is collected in a dirty tank and chips or sludge are first filtered by a magnetic body and discharged to a chip box through a scraper. Then, the cutting oil is secondly filtered by a first and a second filtering fabric and re-fed to a pump room. When the holes of the filtering fabric are bridged by diatomite, the filtered cutting oil is collected in a clean tank. A system measures the pressure of the filtering fabric to sense the clogging of the filtering fabric. When the pressures is less than a set value, the cutting oil is re-fed to all kinds of machine tools or a cutting oil storage tank. When the pressure is more than or the same as the set value, the direction of the cutting oil is controlled to remove the clogging of the filtering fabric and to re-feed the cutting oil to the pump room. After that, the filtering fabric filters chips or sludge again.

Abstract: PURPOSE: Provided is a prodrug of pharmaceutically active peptide. A pharmaceutical composition comprising the prodrug and a pharmaceutically acceptable carrier are also provided. The prodrug is used for the preparation of a pharmaceutically composition for use in therapy. CONSTITUTION: Peptide prod rugs of the general formula (I): X-L-Z, wherein X designates a pharmaceutically active peptide sequence, e.g. Leu-enkephalin; Z designates a peptide pre-sequence of 2 to 20 amino acid units, preferably comprising lysine and glutamic acid; and L is a linking group comprising from 3 to 9 backbone atoms, wherein the bond between the C-terminal carbonyl of X and L is different from a C-N amide bond. Preferably, the bond between X and L is an ester bond. It has been found that it is possible to obtain a remarkable increase in the resistance towards degradation by proteolytic enzymes such as carboxyl A, pepsin A, leucine aminopeptidase, alpha -chymotrypsin when masking a pharmaceutically active peptide as a prodrug of the formula (I). The prod rugs of formula (I) are cleaved by the blood plasma enzyme butyryl cholinesterase indicating a readily bio reversibility. It is believed that the stability towards enzymatic cleavage is due to an induced helix-like structure.

Filed: 2000-01-14
Abstract: PURPOSE: A mold manufacturing method for precision casting is provided to obtain a product excellent in surface quality by using graphite as slurry and sand material for reducing gas holes on the product surface. CONSTITUTION: A graphite is used as slurry and sand material in casting stainless steel or precipitation hardening stainless steel doped with a large amount of chromium.
