摘要:
A time required for actually starting encrypted communication after a trigger of an encrypted communication is shortened. When a key exchanging process is to be applied in order to exchange key information upon encrypting a communication performed between a communication terminal 11 and a gateway device 25, a network relay device 15 relays the key information, contents of the key exchanging process are divided into a former-half process and a later-half process, and the network relay device 15 executes the former-half process substitute for the communication terminal 11 to establish “IKE SA”. Then, information obtained as the result of the former-half process is transferred from the network relay device 15 to the communication terminal 11. Then, the later-half process of the key exchange process is executed between the communication terminal 11 and the gateway device 25, the communication terminal 11 and the gateway device 25 share common key information with each other to establish “IPsec SA”, and an encrypted communication is performed by using this key information.

It is possible to perform access from a global network side to a private network side so as to realize mutual communication between the global network and the private network while maintaining security. A table setting unit (307) decides a correspondence between a private IP address and a global IP address and registers it in an address conversion table (310). The address conversion table (310) holds the private IP address and the global IP address while correlating them to each other.

An access controller not requiring a large amount of resources such as a memory device and not needing to change the list of secure host devices each time the configuration of a network is changed. On receiving a DNS response through an access control section (103) of the access controller (100) a secure host list creating section (104) of the access controller registers the name of the secure host device contained in the DNS response, the IP address, and the IP address of a communication terminal which is a request of the DNS in a secure host list holding section (105) of the access controller (100) when the IP address of the host device contained in the DNS response is the one of the secure host device. The secure host list creating section (104) discards a packet when the communication terminal which is the packet sender is a normal communication terminal and when the packet address is stored in the secure host list holding section (105) and reports nonaccessiblity to the normal communication terminal.

An access control unit and an access control method are provided for controlling an access to a secure host efficiently by reducing the consumption of resources such as a memory. In this access control device, an access control unit (302) performs an access control in accordance with whether the target IP address and the sender IP address of a packet are the IP address of a secure terminal or host or the IP address of a general terminal or host, while referring to a host list stored in a host information storage unit (304). The host information storage unit (304) stores the domain name and the IP address of a general host in an external network (200), as the host list. A host list updating unit (305) inquires the host list of the host information storage unit (304) whether the unregistered host is the secure host or the general host, and updates the host list in accordance with the result of the inquiry.

A method enhances fatigue strength of ear portions which are high fatigue risk parts in a torsion beam almost without bringing about disadvantages in terms of productivity and cost. A torsion beam is formed with a portion of the tubular body into an approximately U-shape in cross section by crushing the portion of the tubular body in the radial direction and, thereafter, due to bending with a bottom line set as a belly side of bending, a bending strain of 2 to 6% in the tube longitudinal direction on a tensile side is imparted to the ear portions.

An athletic wear 1 of the present invention is formed of first clothing fabric F1 having small elastic modulus and second clothing fabric F2 having larger elastic modulus than first clothing fabric F1. First belt part 10 is formed by second clothing fabric covering circumference of upper part of pelvis Bh in wear 1. First belt part 10 essentially continuously comprises belt front part 11, belt back part 13 and pair belt side parts 12 covering upper part of pelvis Bh. Upper edge line of belt part slopes as extends from center of belt back part to center of belt front part.

There is provided a portable terminal device that enables a user to operate all buttons to be operated by moving only one finger of one hand carrying the terminal when operating the terminal equipped with both a touch panel and a stationary operation section and that exhibits superior operability. The portable terminal device has enclosures 11, 12 with a movable portion, a display section 17 capable of displaying visible information showing an operation target area, and a touch sensor 13 that detects a position on a display screen of the display section touched by a user's finger, or the like. The device is further provided with a shape detection section for detecting a change in the shape of the enclosure; an input operation management section for managing a position detected by the touch sensor and an operation target area of each of pieces of visible information displayed on the display section in an associated manner; and a display control section that automatically makes a change to at least display positions of the respective pieces of visible information about the operation target displayed on the display section in accordance with a change in shape of the enclosure detected by the shape detection section.

A wireless terminal device which can be connected to a wireless LAN service to which the terminal can be connected without regard to the identifier for specifying a wireless LAN service, a wireless connection method, and a program are provided. A wireless terminal device (100) stores common authentication information (200) that can be verified by a plurality of access points (111 to 113) in common in a common authentication information DB (104) in advance. Before connecting to the wireless LAN, the wireless terminal device repeats a trial in order to be authenticated with respect to the connectable wireless LAN service according to the common authentication information (200) until the connection is made.

A safety controller provides a safety output to a target controlled system such as a magnet contactor based on an input from an input device such as a safety door switch to thereby control operation of machine equipment. Safety output parts serve to transmit a solid-state output as the safety output and a connection output part transmits a connection output to another safety controller. A control part having two CPUs controls the safety output and the connection output according to a program based on the input from the input device. Two or more of such safety controllers are connected through their connecting output parts and the connecting input parts to together form a safety system.
摘要:
In a structure for mounting a filter in a compressor, a mounting member is connected to the filter. A receiving hole is formed in a housing of the compressor for receiving therein the mounting member. A first fitting portion is formed on an inner circumferential surface of a holding portion of the filter. A second fitting portion is formed on an outer circumferential surface of the mounting member for having fitting relation to the first fitting portion for an overlap distance in a radial direction of the receiving hole. When the mounting member is received in the receiving hole with the fitting relation, the filter is disposed in a fluid passage of the housing. A clearance having a dimension is formed between an outer circumferential surface of the holding portion and an inner circumferential surface of the receiving hole. Minimum value of the dimension is smaller than the overlap distance.
