摘要:
A mobile wireless communication control device includes a moving object information holder that stores a communication state of each moving object which moves in a plurality of wireless zones and information showing a wireless zone to which the moving object belongs, and a call admission determinator that refers to the information held by the moving object information holder, and determines whether a moving object which is going to start communications can start the communications on the basis of the number of calls of moving objects in communication in a first wireless zone to which the moving object which is going to start the communications belongs, and the number of calls of moving objects in communication in a second wireless zone adjacent to the first wireless zone.

An article sales data processing apparatus comprises a first reading unit configured to read an article identification code from a first medium attached to an article, a second reading unit configured to read the article identification code from a second medium attached to the article, a determination unit configured to determine whether the article identification code is the code read by the first reading unit or the code read by the second reading unit, and a control unit configured to separately display, on a display unit, article sales data obtained from the article identification code determined to have been read by the first reading unit and article sales data obtained from the article identification code determined to have been read by the second reading unit.
摘要:
A radio-communication apparatus carries out movement of a dielectric element toward an antenna of RFID reader/writer when the RFID reader/writer cannot perform within a predetermined time radio-communication with a data carrier mounted on the RFID label that is arranged on a rolled base sheet passing between the dielectric element and the antenna. The movement is performed step by step to stop the dielectric element at positions at each of which the radio-communication is executed until the reader/writer can perform radio-communication with the data carrier within the predetermined time at any one of the positions.
摘要:
Upon receiving a command for writing data to a transponder, a reading unit performs radio communication with the transponder to which data should be written, thereby reading, in non-contact fashion, a data item stored in the transponder. A collating unit collates the data read by the reading unit with a data item to be written to the transponder. A control unit performs radio communication with the transponder, thereby writing the data item to the transponder, when the data items are not identical, and skips the writing of the data item when the data items are identical.

Phosphonium salts represented by the general formula (I) wherein R1 and R2 each represents a phenyl group which may be substituted by a lower alkyl group, R3 represents a phenylene group which may be substituted by a lower alkyl group, R7 and R8 each represents a hydrogen atom or a hydrocarbon group having 1 to 12 carbon atoms which may be substituted and R9 represents a hydrogen atom or a hydrocarbon group having 1 to 5 carbon atoms which may be substituted; processes for producing the same and uses for the same; phosphines providing the same, and processes for producing said phosphines.
摘要:
A process for producing diamines which comprises the steps of: (1) reacting a dialdehyde with ammonia and hydrogen in the presence of an alcohol and a hydrogenation catalyst to synthesize the corresponding diamine; (2) separating and recovering the alcohol by distilling the reaction mixture obtained by the step (1); (3) separating the diamine by purifying the distillation residue obtained by the step (2); and (4) feeding at least part of the alcohol recovered in the step (2) to step (1); said step (1) comprising maintaining the amount of ammonia at a level of at least 200 moles per mole of the primary amine that has formed in the step (1) and accumulated in the reaction vessel for step (1). The process can produce diamines commercially advantageously and in high yields, the diamines having little impurities.
