摘要:
A field device connected to a network includes: a storage section; a communication section for performing communication via the network; and an arithmetic control section for controlling the field device entirely by executing a main task under an execution environment, and controlling an operation mechanism that operates under the execution environment. The operation mechanism assigns a group identifier, a unique address space and a unique name space to an additional task being started.

In an access control method for performing access control on resources of a device, the access control method includes: activating a program management function, an access management function and a resource management function on a running embedded OS (Operating System); segmenting plural applications operating on the device to allocate a segment identifier to each of the segmented applications, by the program management function; if access to the resources from an application is requested, deciding enabling and disabling of the access to the resources from the application by referring to an access enabling and disabling list based on the segment identifier, by the access management function; and if the access is enabled, notifying the application of a method of referring to the resources in which a request for acquisition is made, through the access management function and the program management function, by the resource management function.

A fuel cell and a fuel cell stack. A cathode (41) of a fuel cell (3) assumes the form of a square plate and is composed of a lower layer (61) on a side toward a solid oxide body (37), and an upper layer (63) which covers the outer surface of the lower layer (61). The lower layer (61) is square in planar shape, and its four side surfaces stand upright in its thickness direction. The upper layer (63) is square in planar shape and has a square main surface (outer surface) (65) which faces outward in its thickness direction, and side surfaces at its four sides. Opposite side surfaces (67) and (69) residing in a flow path extending between an oxidizing gas inlet side and an oxidizing gas outlet side are flat and inclined toward the center of the outer surface (65).

The present invention provides a cooling structure of a cylinder block, the cooling structure being capable of improving a cooling performance of sliding surfaces. A cylinder block includes a plurality of cylinders, and pistons are respectively inserted into the cylinders through openings. Each of the pistons performs reciprocating sliding on a sliding surface which defines the cylinder. A plurality of cooling depressions are formed on an outer peripheral surface of the cylinder block. Each of the cooling depressions extends from a front end surface of the cylinder block on a dividing wall located between the two adjacent cylinders and is formed by reducing the thickness of the dividing wall so as to reduce a thickness of a portion between the sliding surface and the outer peripheral surface.

The allocation of hardware resources to distribution applications is enabled without using effective task priority available only in field devices. A distribution system makes a plurality of field devices connected with each other through a network (N) operate a plurality of distribution applications (distribution AP) in parallel. The distribution system is provided with an importance adjustment unit (3) that calculates relative values indicative of the task priority in the field devices in accordance with the importance of the distribution AP designated for every distribution AP and a resource allocation unit (13) that allocates the hardware resources of each field device to each of the tasks of which the distribution AP are composed in accordance with the relative values in the field devices calculated by importance adjustment unit (3).
摘要:
The present invention provides a mobile communication terminal, an IC card, a mobile communication system, a program, and a communication charge notification method capable of easily indicating roaming communication charges and preventing a user from being unexpectedly charged for communication. A mobile phone 10 detects that it is located in a country B as a roaming area based on information transmitted from a base station 32, inquires of a charge information related server 24 whether or not a communication charge information stored in a storage section 16 is the latest communication charge information, when the communication charge information is not the latest communication charge information, updates the stored communication charge information based on the communication charge information transmitted from the charge information related server 24, reads the communication charge information of the country B from the storage section 16, and displays the communication charge information on a display section 14.
摘要:
Disclosed is a field device which constitutes a plurality of distributed systems to perform a data communication with another field device on a network. The field device includes: an application execution section to execute a distributed application based on each distributed system; a storage section to store setting information on virtual communication addresses allocated to each field device constituting the plurality of distributed systems for each distributed system; and a control section to determine whether a requested data communication is in a same distributed system based on the stored setting information on the virtual communication addresses when the data communication is requested by the application execution section. If the data communication is in the same distributed system, the control section notifies a management section of a virtual communication address of a destination device, and requests the management section to perform the data communication with the destination device.

摘要:
A low noise, hermetic motor-driven compressor suitable for used in a refrigerator or an air-conditioner is disclosed in which a closed container has a spherical wall portion on which a combined motor-and-compressor assembly is supported via a suspension mechanism, and the suspension mechanism includes two snubber stays having spherical portions complementary in contour to the shape of the spherical wall portion of the closed container and welded to the spherical wall portion. The spherical wall portion increases the stiffness of the closed container, which stiffness is enhanced by the spherical portions of the snubber stays. The thus reinformed closed container is unlikely to vibrate in resonance with the vibration of the combined motor-and-compressor assembly. Thus, the hermetic motor-driven compressor is able to operate silently.
