Abstract:
PROBLEM TO BE SOLVED: To provide an error response method at the time error generation in motion of a machine, in particular, improved in a disadvantage of a prior art. SOLUTION: In this error response method when the error or a trouble is generated, for example, in a drive unit, in the motion of the machine transmitted with master shaft information, the motion is carried out by using at least one master shaft, and a cam plate having at least one input side and one output side and controlled by the master shaft, and error response is started to be executed using a process variable applied onto at least the one input side of at least one cam plate, when the trouble is generated in the transmission of the master shaft information.

PROBLEM TO BE SOLVED: To provide a simpler time synchronizing method in a periodically operating communication system. SOLUTION: The time synchronizing method is a method for temporally synchronizing subscribers connected via a periodically operating communication system. In the method employing a system of transmitting time information to the subscribers to be synchronized in order to perform initialization, absolute time information is simultaneously transmitted to all the subscribers to be synchronized, the local time of each of the subscribers is re-calculated from the absolute time information and the periodic time after at least one of the known periodic time or a plurality of periods, thereby performing synchronization.

Abstract:
PROBLEM TO BE SOLVED: To provide an efficient method for synchronizing at least one participant with a central participant by avoiding defects of prior arts. SOLUTION: A telegram is formed to be a data telegram. Unlike prior arts, synchronization information is not transmitted in the form of a specific short Master Synchronization Telegram. Instead, the synchronization information is included in the data telegram as an element of the telegram, i.e., a telegram that transmits driving or process data from the central participant to the at least one further participant (or vice versa). The communication data are defined based on the end of the synchronization information contained in the data telegram. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To solve a problem of a conventional technology that two overlapped data packets cannot be used in an IP communication channel and data communication in a data network is disturbed thereby. SOLUTION: A control unit is connected to a switching unit and blocks transmission of received external data packet via a data output side in a first operating mode when an internal packet is outputted via the data output side by using a first data preparation unit and blocks the transmission of the received data packet by using an intermediate amplifier when the internal data packet is not outputted via the first data preparation unit as its control.

Abstract:
PROBLEM TO BE SOLVED: To provide a solution method capable of ensuring the highest possible transmission probability with respect to the attached data. SOLUTION: This data transmission method is among subscribers who conduct communication using a data bus, at least a first time window and at least a second time window are used during cycle time which has been previously defined to a transmission cycle, with respect to the exchange of data telegrams among the subscribers. The first time window is used for the transfer of processing data, the second time window is used for transfer of attached data, and the length of data telegram, showing the attached data, can be set within the length of corresponding time window.

Abstract:
PROBLEM TO BE SOLVED: To provide an improved printing correction method and a printing correction device. SOLUTION: The method comprises a step to detect the positions of at least two printed marks placed on the products, a step to evaluate the positions of the printed marks, and a step to automatically correct the printing from the positions of the printed marks, and the correction includes the correction of the length of the print. The device comprises the unit to detect at least two printed marks on the products. The first at least one printed mark is located at the front part in the transfer direction of the product and the second at least one printed mark is located at the rear part in the transfer direction of the product. The correction is done automatically using the correction device and the automatic correction includes the correction of the length of the print. COPYRIGHT: (C)2006,JPO&NCIPI
