An action chart describing an operation of an automated manufacturing machine includes subperiods into which an operation period from a start to an end of the operation of the automated manufacturing machine is divided. The action chart includes element actions included in the operation of the automated manufacturing machine. The element actions on the action chart are assigned to the subperiods and each include an action identifier including qualitative information about the element action, and a numerical table or numerical parameters. The action chart is read. The action identifiers on the action chart are converted into program elements stored in a manner associated with the action identifiers. A numerical value in the numerical table or the numerical parameters is set for each program element. The program elements are combined together in an order of the subperiods on the action chart.

An ballpoint pen has: a tip body made of metal having an front edge part and a plurality of inward protrusions; a ball rotatably embraced between the front edge part and the inward protrusions; and a rod part urging the ball forwardly and bringing the ball into close contact with the inner surface of the front edge part, wherein ink outflow gaps are formed each between the adjacent inward protrusions, the rod part is inserted into the central part of the ink outflow gaps, the diameter of a virtual inscribed circle of the central part of the ink outflow gaps is larger than the outside diameter of the rod part, and a minimum dimension of each the ink outflow gap is smaller than the outside diameter of the rod part.

The present invention relates to a starch ester having short- and long-chain acyl groups wherein hydrogens in reactive hydroxyl groups in the same starch molecule have been replaced by C short-chain acyl groups and C long-chain acyl groups. The degree of substitution by the short- and long-chain acyl groups are regulated so as to make the starch ester thermo-plasticized and moldable even in the absence of a plasticizer. Accordingly, the starch ester of the present invention can be used as a biodegradable thermoplastic plastic material which can be thermo-plasticized in the absence of a plasticizer.

Starch ester

A spring ( ) for pressing a ball ( ) forward is disposed within a tip body ( ) and a holder ( ). The spring ( ) includes a straight part ( ) and a coil part ( ). The straight part ( ) is inserted into the tip body ( ), and the coil part ( ) is disposed within the holder ( ). A protrusion ( ) is provided on the inner surface of the holder ( ). The coil part ( ) climbs over the protrusion ( ) and its engagement and stopping are set up.

Ball point pen

Ink and a follower advancing with consumption of the ink are stored directly in the inside of a barrel having a pen point at its forward end. An outer tail plug constituted by a closed-end cylinder is fitted to a rear outer surface of the barrel. An air course is formed between the rear outer surface of the barrel and an inner surface of the outer tail plug to communicate with the inside of the barrel through a rear end aperture portion of the barrel. At least one air hole is provided ahead of the rear end aperture portion of the barrel to make the air course communicate with the outside air.

A polyester-grafted starch-polymer alloy is capable of imparting practical flexibility and toughness to moldings with no or only a little plasticizer. The polyester-grafted starch-polymer alloy comprises a blend of a polyester-grafted starch (a starch which has polyester graft chains on the starch molecule, with the terminal hydroxyl groups of the polyester graft chains and the hydroxyl groups connected directly to the starch entirely or partly blocked with the ester group) and an independent polyester (a polyester which is constructed of the same unit as said polyester graft chain, with its terminal hydroxyl groups entirely or partly blocked with the ester group) which are uniformly mixed together. A method of preparing the alloy and thermoplastic resin compositions containing the alloy also are disclosed.

Polyester-grafted starch-polymer alloy

A starch derivative which, when incorporated with no or only a little plasticizer, yields moldings having good flexibility, toughness, and water-relating properties for practical use comprises an esterified, polyvinyl ester-grafted starch derivative which is formed by esterifying starch and grafting starch with a polyvinyl ester. The polyvinyl ester is derived from one or more saturated or unsaturated aliphatic acids or aromatic carboxylic acids having 2 to 18 carbon atoms.

Method for producing starch esters, starch esters, and starch ester

A starch derivative which, when incorporated with no or only a little plasticizer, yields moldings having good flexibility, toughness, and water-relating properties for practical use is an esterified, polyester-grafted starch which is formed by esterifying starch and grafting the starch with polyester. The esterification involves the introduction of one or more acyl groups consisting of saturated or unsaturated aliphatic acid groups or aromatic carboxylic acid groups having 2 to 18 carbon atoms and the polyester is one which is formed from one or more 4- to 12-membered lactones by ring-opening polymerization, with the terminal hydroxyl groups being almost completely blocked by esterification.

Esterfied, polyester-grafted starch

Disclosed herein is a new cationic starch and cationic starch paste or slurry. The starch paste or slurry has a low cation equivalent value despite its high nitrogen content and also has a low solution viscosity despite its high molecular weight. The cationic starch and cationic starch paste or slurry is formed by substitution with a one or both of quaternary ammonium salt or a tertiary amino group, characterized in that its nitrogen content (X) due to the quaternary ammonium salt and/or tertiary amino group is related to its cation equivalent value (Y) as defined below:
