摘要:
A data processing apparatus includes a storage format setting unit for setting a storage format in an interactive manner in order to store acquisition data, acquired from a control appliance connected thereto, a storage file forming unit for forming a storage file used to store the acquisition data based upon the storage format set by this storage format setting unit, and a storage unit for storing the acquisition data acquired from the control appliance in the storage file formed by this storage file forming unit according to the storage format set by the storage format setting unit.
摘要:
A data processing method which makes it unnecessary to run a user application program describing detailed conditions under which data on a device having a memory are acquired each time a system is started. A main controller forms a text format file as a data acquisition condition for a PLC from which data is to be acquired so that the data acquisition condition is associated with a label name, the data acquisition condition including a supervisory interval for supervising the status of the PLC and the operation status of the PLC for setting a trigger condition for starting data acquisition. When receiving the label name and the corresponding data acquisition condition from the main controller, a subcontroller develops and stores is the received data acquisition condition in a memory so that the data acquisition condition is associated with the label name. When receiving only the label name from the main controller, the subcontroller compares the data acquisition condition that is developed and stored in the memory with data of the PLC, acquires data from the PLC when the data acquisition condition is satisfied, and transfers the acquired data to the main controller.

A system for measuring a peak frequency of a signal applies a Maximum Entropy Method (MEM) to the signal obtained through transmission and reception of an electromagnetic wave to a subject to obtain a frequency of a peak component to be measured, thus permitting to make an appropriate assessment on a state of the subject. A signal analysis unit performs a spectrum estimation utilizing the MEM applied to a signal part of the phase difference signal with a predetermined short analysis duration, from a phase difference signal obtained by an electromagnetic wave transmitting and receiving unit, to obtain a frequency indicative of occurrence frequency of the peak component, and conducts repeatedly the same process, while shifting a position to be analyzed, corresponding to the analysis duration, thus introducing continuously the frequency. It is therefore possible to know a transition with time of the frequency of the peak component.

The present invention relates to a data processing apparatus for transmitting data to and receiving data from a device to be controlled which is connected to the data processing apparatus by way of a communications line. When application programs submit a request to the device for control, a control request is issued from a plurality of application programs in the form of a unified common packet. A communications manager converts the control request into an actual packet to be actually transmitted to the device to be controlled and outputs the thus-converted actual packet to the device.

Amid 10 having concave portions 13 having a predetermined shape in front view is prepared. A slurry 20 is filled into the concave portions 13. The mold 10 storing the slurry 20 is placed on an upper surface of the ceramic green sheet 30. A pressure inside the sheet 30 is lowered through a pile 51 and a sintered metal 40. The sheet is heated by a hot plate 60. With these, a solvent in the slurry 20 is permeated into fine pores of the sheet 30 to be evaporated. The pre-dried 3-D forming portion is dried without deformation.

A wireless communication system includes a plurality of mobile stations and a base station configured to connect the mobile stations wirelessly, wherein the base station includes a response request signal transmission module configured to transmit a response request signal to the mobile stations, and a first wireless connection control module configured to disconnect the wireless connection between the mobile stations when a response signal is not received from at least one of the mobile stations to which the response request signal has been transmitted.
摘要:
A mold having concave portions in a predetermined 3-D shape is prepared. A slurry is filled into the concave portions and the mold storing the slurry is then placed on an upper surface of a ceramic green sheet. A pressure inside the sheet is lowered through a pipe and a sintered porous metal support with the green sheet being heated by a hot plate. Accordingly, a solvent in the slurry is permeated into the fine pores of the green sheet and evaporated, thereby drying the 3-D forming portion without deformation.
