Abstract: Provided is an aspartic acid composition containing aspartic acid and an impurity, the impurity containing at least one selected from the group consisting of an amino acid other than aspartic acid, an organic acid, and salts of the amino acid other than aspartic acid and the organic acid, a content of the impurity being 0.02% by mass or more and 1.1% by mass or less. Also provided is a method for producing polysuccinimide, the method including performing a polymerization reaction of the aspartic acid using the aspartic acid composition. Also provided is a polysuccinimide composition produced by the method for producing polysuccinimide.

Abstract: There are provided an operation number control device and a method for controlling the same that can level the operation times of the fluid machines, which are connected to the operation number control device. A fluid machine system comprises a plurality of fluid machines, and an operation number control device capable of individually controlling start and stop of the fluid machines. The operation number control device sets a continuous operation time for each of the fluid machines based on total operation times of the fluid machine and other fluid machines. When among fluid machines in operation, there is a fluid machine for which the continuous operation time set for the fluid machine has elapsed and there is a fluid machine at stop, the operation number control device causes the fluid machine at stop to start and causes the fluid machine to stop.

Abstract: A sheet-shaped check valve which opens and closes the injection passage is placed in the check valve chamber, an injection discharge passage portion connected to the compression chamber of the injection passage and the check valve chamber open from an outer surface of the fixed scroll, a lid body is attached to openings of the injection discharge passage and the check valve chamber such that the check valve is sandwiched between the openings and the lid body, and the injection discharge passage and the check valve chamber are hermetically closed, thereby forming the injection passage. According to this, it is possible to provide a reliable, efficient and inexpensive compressor with an injection mechanism.

Abstract: Regarding a laser welded body in which a laser transmissive/absorptive molding member containing a PBT-based material and a laser absorptive molding member containing a PBT-based material are integrated with each other by laser welding, the following laser welded body is proposed as a laser welded body in which a bond strength can be further increased. A laser welded body having a structure in which a member I and a member II are integrally bonded to each other, the member I contains 0.0005 to 5.0 parts by mass, with respect to 100 parts by mass of a polyester-based resin A, of a laser transmissive/absorptive coloring material capable of transmitting and absorbing laser beam, and the polyester-based resin A contains at least a polybutylene terephthalate copolymer resin, the member II contains 0.15 to 10.

Abstract: A method of measuring a target substance contained in a sample may include passing a complex formed by allowing the target substance to react with a predetermined carrier through a pore provided in a substrate. A size of the complex may be measured based on change in electrical characteristics occurring when the complex is passed through the pore in the pass-through step. The number of molecules of target substance may be determined based on the size of the complex measured in the measuring step.

Abstract: The present invention pertains to a method for producing a mixture including an injected engine fuel from an injector, a combustion engine intake-air and an evaporative gas from the engine fuel. The method includes the steps of measuring a characteristic of the evaporative gas and changing step for changing a mixing ratio of the evaporative gas to at least one of the injected engine fuel and the combustion engine intake-air, according to the measured characteristic of the evaporative gas, by changing a flow rate of the combustion engine intake-air.

Abstract: A system and method for locating intelligence data like the courtesy or monetary amount on a document. The intelligence data is presented in the form of a matrix of binary data which corresponds to image data associated with a financial document like a check or deposit slip. From the matrix of binary data, an input character located on a predetermined side of the data is examined. If the input character is identified as a clue character, it means, generally, that a portion of the matrix of binary data which is associated with the clue character may be the binary data associated with the monetary amount. In the embodiment described, the clue characters are asterisks (*) and dollar signs ($) of different expected varieties. Having found the binary data associated with the monetary amount, it can be subjected to character recognition techniques to machine-read the monetary amount on the document.
