Granted: 2003-12-23
Abstract: A cylinder block is coupled to a cylinder block/cylinder head coupling surface of a cylinder head by ten bolts which are disposed to surround outer peripheries of combustion chambers.          In order to enhance sealability of an opening of a cooling water passage defined radially outside the bolts as viewed from the combustion chambers, the cylinder block and the cylinder head are further fastened to each other by a bolt disposed in the vicinity of the opening. Thus, the fastening force of the cylinder block/cylinder head coupling surface can be increased to increase the degree of freedom in design of the opening of the cooling water passage defined in the coupling surface.

Granted: 2002-08-06
Abstract: A porous implant and method of making such is disclosed. A mold form material (164) is created by adhering solid particles together to form a porous network. A liquid phase of a final product is forced through the interstices of the mold form (164), and then most of the liquid material is forced out of the interstices leaving a thin coat (162). Next, the thin coat is cured to produce a thin coat of a polymer such as silicone rubber (162). Next, the mold form material (164) is dissolved out creating a porous structure containing only the cured polymer.

Title: Interference reduction in shared-frequency wireless communication systems
Inventor: ARNOLD HAMILTON WEBSTER
IPC: H04B7/26
Filed: 1996-05-01
Granted: 2001-06-12
Abstract: An apparatus and method for reducing interference between an uplink transmitter of a fixed satellite service (FSS) system (150) and an uplink or downlink receiver of a local multipoint distribution service (LMDS) system (100) are described. An ordered list of the preferred uplink transmission frequencies is assigned to all FSS uplinks located in a particular cell of the LMDS system (100). Different ordered lists are used in different cells (105-1 -105-3) of the LMDS system (100), while uplinks located in the same cell can utilize the same order list. Further, the ordered list may be selected by the LMDS service provider such that the impact of interference from FSS uplinks can be readily predicted and minimized. Therefore, the system allows simultaneous access to a shared frequency band for both LMDS and FSS systems (100 and 150).

Abstract: A sealing structure for a first stage stator blade of a gas turbine (1), capable of preventing the leakage of sealing air from the interior of the blade even when the stator blade inclines due to thermal stress occurring therein, comprising an arcuately formed rear flange (12) of a first stage stator blade (31), a linear rib (10) provided on the rear flange, and a stator blade support ring (13) in contact with the rib to form a sealing surface.  When the rear flange (12) and the stator blade support ring (13) are inclined relatively to each other as shown by 13a, 13b, an upper or lower end of the horizontal rib (10) and a surface of the circular stator blade support ring (13) are brought into linear contact with each other, so that there arises no clearance that prevents the leakage of the sealing air. When a stator blade support ring (13) of a conventional gas turbine is inclined, an arcuate clearance occurs between the support ring and a rear flange (12) since no horizontal rib (10) is provided, so that the sealing air leaks from the interior of the gas turbine into a gas passage. The present invention can prevent this inconvenience.

Granted: 2006-05-09
Abstract: A detection apparatus discriminates between metallic mines and other buried objects by detecting the depth of the object, the size, the shape and the orientation of the object and the electrical properties of the object. A dielectric sensor having a first electrode and a second electrode is used in one embodiment. The first electrode is driven with a varying voltage to establish a varying electric field through the ground to the second electrode. The voltage magnitude and phase of the second electrode are measured. Another apparatus, a magnetometer sensor, detects objects containing metal located below the surface of the ground. This apparatus has a plurality of parallel, spaced linear conductor sets disposed in proximity to the ground. An electromagnetic field is imposed in the ground with a dominant spatial wavelength through the conductor elements. A resulting electromagnetic response of the object in the ground to the imposed magnetic field is sensed.      The conductor sets may have varying number of individual conductors.

Abstract: The disclosed system and method provide a customer with the ability to obtain temporary caller identification services in an Advanced Intelligent Network. The customer initiates the service by dialing a call to a feature access code and does not require the intervention of a service representative. The call by the customer is recognized as a request for.caller identification service. On the basis of the recognition, an association is retained between the line number and the Service Switching Point serving the line number. This retained association may be used later in the activation of the temporary caller identification service for the requested line number. The call is routed to a rental service interface through which rental information from the caller may be collected. This rental information may be compiled into a rental agreement that is used as the basis for activation of the temporary caller identification services with respect to the requested line number. Optionally, confirmation of the activation of caller identification service is provided to the customer during the communication.

Abstract: A call center is configured to include a capability for generating measures of occupancy for one or more agents. At least one value characterizing an occupancy measure determination for a given agent is stored in a memory associated with the call center, and used in generating an occupancy measure for that agent. In an illustrative embodiment, a set of stored values for the given agent includes an initial occupancy value for the agent, expressed in terms of a percentage. The occupancy measure for the agent may then be set to the initial occupancy value upon a log-in by the agent, so as to avoid undue oscillation in the occupancy measure after log-in. The set of stored values for the given agent may also include, for example, a limit which specifies a maximum amount of time for a designated activity which is to be considered as occupied time in generating the occupancy measure, or a limit which specifies a maximum effect of a designated activity in generating the occupancy measure. The designated activity may be, for example, after call work or auxiliary work performed by the agent.

Abstract: A method and apparatus are disclosed for analyzing the operation of one or more network gateways, such as firewalls or routers, that perform a packet filtering function in a network environment. Given a user query, the disclosed firewall analysis tool simulates the behavior of the various firewalls, taking into account the topology of the network environment, and determines which portions of the services or machines specified in the original query would manage to reach from the source to the destination. The relevant packet-filtering configuration files are collected and an internal representation of the implied security policy is derived. A graph data structure is used to represent the network topology. A gateway-zone graph permits the firewall analysis tool to determine where given packets will travel in the network, and which gateways will be encountered along those paths. In this manner, the firewall analysis tool can evaluate a query object against each rule-base object, for each gateway node in the gateway-zone graph that is encountered along each path between the source and destination. A graphical user interface is provided for receiving queries, such as whether one or more given services are permitted between one or more given machines, and providing results. A spoofing attack can be simulated by allowing the user to specify where packets are to be injected into the network, which may not be the true location of the source host-group.
