摘要:
An identification information management system according to the present invention comprises a plurality of terminals communicable with servers and a site management apparatus which manages site containing the terminals. The terminal has an identification information processing unit which assuming that a one-way hash function is f(x) and a terminal-unique ID is a, generates values x satisfying a conditional equation f(x)=a as identification information. When acquiring multiple items of identification information, the site management apparatus substitutes the identification information as the value x into f(x) and decides whether f(x)=a is satisfied, thereby deciding the terminals.

A DNS name resolution system according to the present invention has a DNS server; a terminal which generates and transmits a DNS query packet containing DNS name information described in accordance with a specific description method and whose destination is said DNS server; and an override agent which is disposed along a communication path between the terminal and the DNS server. The override agent has a capture unit which captures a DNS query packet transmitted from the terminal; an analysis unit which stores in advance information concerning the specific description method based on which the DNS name information was described by the terminal, analyzes the DNS name information contained in the DNS query packet captured by the capture unit based on the specific description method, and selects the information for reply to the terminal based on the analysis results; and a reply unit which generates and transmits a DNS response packet containing the information for reply selected by the analysis unit and whose destination is the terminal.

The electrical contact 1 has a contact member 16 that contacts the mating contact T. The contact member 16 has a first resilient contact arm 16a which extends rearward from the lower top wall 15, a connecting section 16b which is bent downward at the rear end of the first resilient contact arm, and a second resilient contact arm 16c which extends forward from the connecting section 16b. In cases where the mating contact T tends to be pushed further inward after the insertion of the mating contact T has been completed, the area in the vicinity of the rear end of the first resilient contact arm 16a contacts the upper top wall 14.

A first spring guide fitting the outer periphery of one end portion of a coil spring is provided at an end wall portion of a valve casing, and a second spring guide fitting the inner periphery of the other end portion of the coil spring is provided at a valve element so that the first and second spring guides do no interfere with each other. Further, a valve element of the check valve is provided with an elastic sealing member having a lip portion to be seated on a valve seat portion of the valve casing. Moreover, the valve element is formed with a bypass hole communicating upstream and downstream sections of the check valve.

A lever type connector has a lever (60) and a housing body (10) consisting of a main body (20) and a wire cover (40). The lever (60) has a pair of arms (65), and an operating part (66) which connects the arms (65) at one end. When the lever (60) is mounted on the housing body (10), the ribs (43) on the inclined parts (42) of the wire cover (40) engage with the arms (65) and act to spread the arms (65) outward. When the arms in this outward-spread state are moved over the posts (22) so that the arms reach positions directly above the posts (22), the arms undergo elastic recovery inward, and act to move the openings (62) into positions in the vicinity of the posts (22).

A method and an apparatus for controlling an injection of a die-casting machine, the apparatus having an open-shut valve for opening and shutting a hydraulic channel through which hydraulic fluid is discharged from a boost cylinder device and a boost cylinder flow-control valve for regulating a flow of the hydraulic fluid discharged from the boost cylinder device. When a highly viscous molten material is injected toward a casting mold and the molten material reaches a gate of the casting mold, an injection resistance is increased. At this time, by regulating the hydraulic channel with the control valves to discharge the hydraulic fluid in accordance with a predetermined program, the boost cylinder device applies further pressure to the injecting piston to assist injection process, thereby preventing inappropriate change in injection speed. Consequently, the open-shut valve is opened to conduct ordinary pressure boosting pressure process.

An assembly of electric connectors and plug connectors and cap connectors used therein has guiding ribs providing for a smooth joining of the plug connectors and cap connectors, Ribs 16a, 16b and 16c extending from the bottom wall 14 are provided respectively in cavities 6, 8 and 10 of the cap connector 1. All ribs are of the same configuration and have outside surfaces 26, 28 perpendicular to the bottom wall 14, an outside surface 30 parallel to the bottom wall and a slanted surface 20 forming a roughly P-shaped cross section. In the plug connectors, slots of the same configuration as said ribs are formed, thus providing smooth connection by limiting vertical and horizontal deviations during their joining.

An electrical connector with electronic noise filtering structure is disclosed. Two slits (42) are formed in metal plate (40), which plate is secured on the rear of the electrical connector with through condenser (2). Slits (42) are formed to be at right angles to the longitudinal direction of the metal plate. The width of slits (42) expands or contracts in response to the housing's expansion or contraction due to temperature, and metal plate (40) adapts and prevents stress from accumulating in the through condenser solder section.

A filter connector (40) for filtering unwanted signals from contacts (46) includes a housing (50) having therewith a subassembly (62) including an auxiliary plate (44) holding capacitors (43) in a spaced array, a grounding plate (42) having holes (41) on the spaced array to receive the capacitors inserted therewithin extending into recesses (49) of a ferrite plate (42) with the ferrite plate contiguous with the grounding plate. Contacts (46) are carried by the subassembly with contact ends (46a) projecting forwardly in the housing and post ends (46b) inserted into a PC board (60). The ground plate (42) includes terminals (54-56) projecting to connect the ground plate to ground circuits of the printed circuit board, suitably bent to provide support for the connector prior to soldering. Embodiments include a molded housing, in one form insert molded (50) around subassembly (62) or premolded (71) with the subassembly (62) secured therein.
