Abstract: The problem to be solved is, when printing a 3D object by using a 3D printer of fused-deposition-modeling type or another type, to enable printing it even when the filament is not supported from underneath by avoiding filament drop by generating force to push the extruded filament to the neighbor filament, and to enable arraying the filaments to a horizontal direction. To avoid filament drop, force that pushes the newly extruded filament to the neighboring filament is generated, and filament drop is avoided. To do so, compression or extension power is generated by controlling the filament cross section by controlling the filament cross-section (i.e., the extrusion amount) and stiffness of the filament is controlled by controlling the temperature or light.

Abstract: The problems to be solved by this invention is that, by using a layering 3D printing, is to generate objects with fine asperity on the surface, especially with images or characters drawn by fine asperity in high speed and exactly. The method in this invention solves the problem that asperity part may be easily dropped off, that the shape of the drawn images or characters is inexact, that the asperity part of the filament is stringy, and that the direction of slicing is restricted. The problems are solved by the following method. Solids with fine asperity on the surface can be generated in high speed and exactly by changing the cross section of filament by changing the print-head motion speed or by changing the filament extrusion speed. Especially, solids with images and characters on the surface represented by asperity by changing the cross section according to a bitmap of images or characters.

Abstract: A method of processing a program for achieving programming with a low dependency on a hardware is provided. A plurality of types of data representations are provided to a packet in accordance with a type of a memory storing the packet. When an operation is performed for the packet, the data representation provided to the packet is identified, and the processing is performed in accordance with the identified data representation. In this manner, the program with the low dependency on the hardware such as a memory can be developed. Also, in a method (compiler) of processing the program used for the development of the program, a precondition is recognized when the processing for the packet is performed, so that a speed of the created object program is increased.

Abstract: A node apparatus capable of performing flexible load distribution and performing a high speed processing of packets, has an interface connecting to multiple packet processors through a switch, stores association information for associating each packet with information of the packet processor, and forwards a packet associated with information of a first packet processor in the association information to the first packet processor. The node apparatus has a control unit that when the first packet processor is determined to be in high load more than or equal to a threshold, updates the association information so that a packet being processable by the first packet processor may also be associated with information of a second packet processor in the association information. The interface forwards a packet associated with the information of the second packet processor in the updated association information to the second packet processor unit.

Abstract: In cooperation between each data center and a WAN, virtual machine migration is carried out without interruption in processing so as to enable effective power-saving implementation, load distribution, or fault countermeasure processing. Each node located at a boundary point between the WAN and another network is provided with a network address translation (NAT) function that can be set dynamically to avoid address duplication due to virtual machine migration. Alternatively, each node included in the WAN is provided with a network virtualization function; and there are implemented a virtual network connected to a data center for including a virtual machine before migration, and a virtual network connected to a data center for including the virtual machine after migration, thereby allowing coexistent provision of identical addresses. Thus, the need for changing network routing information at the time of virtual machine migration can be eliminated, and a setting change for migration accomplished quickly.

Abstract: A lock control technique suitable for voice communication terminals. A voice communication terminal includes an unattended state detecting unit which detects an unattended state of the terminal, when its user leaves the terminal, and a lock control unit. The lock control unit determines whether the unattended state detected by the unattended state detecting unit has continued for a given time period or longer. If determining that the unattended state has continued for the given time period or longer, the lock control unit controls the terminal's communication so that voice input to the terminal will not be transmitted to other parties in conversation and voice of any other party will not be output from the computer.

Abstract: There is a need for providing a content to a user in process of a voice call without interrupting the conversation. A presence server is provided to manage positions, in a virtual space, of a user of each of voice telecommunication terminals and an advertisement sound source provided by an advertisement server. A media server applies a stereophonic process to voice data for each of the other voice telecommunication terminals correspondingly to a relative position between a user of each of the other voice telecommunication terminals and a user of the relevant voice telecommunication terminal. Further, the media server applies a stereophonic process to acoustic data for the advertisement sound source correspondingly to a relative position between the advertisement sound source and a user of the relevant voice telecommunication terminal. In this manner, stereophonically processed data is synthesized to generate voice call data for the relevant voice telecommunication terminal.

Abstract: In a video conferencing system, required bandwidth is suppressed to a lower level and a key person or the like of a conference can be confirmed easily. A presence server 1 manages location information in a virtual space for a user of each conference terminal 2. Each conference terminal 2 sends image data of its own user to another conference terminal 2 in response to a request of that conference terminal 2. Further, each conference terminal 2 receives location information of its own user in the virtual space, sends the received location information to the presence server 1, and receives location information of the other users from the presence server 1. Then, based on the location information of its own user and the location information of the other users, the conference terminal 2 detects forward users located forward from its own user, and receives image data from the conference terminal 2 of each of the forward users.
