Patent number: 6045427Abstract: In an X-ray image intensifier, an incident window on which X-rays are incident is fixed to a support frame fixed to a glass vessel. The incident window has a dome portion and a flat portion around the dome portion, and is fixed to the support frame through an annular brazing sheet. The brazing sheet has brazing material layers. The brazing material layers are melted, thereby welding the brazing sheet, the incident window, and the support frame with each other. A groove is formed in the brazing sheet to form a brazing material puddle, so the brazing material will not reach the input screen of the incident window during melting.Type: GrantFiled: October 10, 1997Date of Patent: April 4, 2000Assignee: Kabushiki Kaisha ToshibaInventors: Hitoshi Yamada, Tadashi Shimizu

Patent number: 6044264Abstract: The invention relates to a mobile communication network and a method for activating intelligent network services in the mobile communication network. In the invention, the mobile services switching center (MSC) operates as the service switching point of the intelligent network. The mobile services switching center stores the service triggers, which service triggers comprise the triggering criteria for the services and the information required for visiting the service control point (SCP). The mobile subscriber's subscriber data in the subscriber database (HLR) is provided with an intelligent network service trigger key which points to one or more service triggers. As the mobile services switching center obtains the trigger key of the mobile subscriber during the call setup, it activates the service triggers indicated by the key.Type: GrantFiled: August 22, 1997Date of Patent: March 28, 2000Assignee: Nokia Telecommunications OyInventors: Seppo Huotari, Veli Turkulainen

Patent number: 6040148Abstract: The present invention relates to a purified stress protein of 86 Kd and fragments thereof isolated from the genus Corynebacterium. Particular fragments include those with apparent molecular weights of 50 Kd and 52 Kd. The stress protein has been found to be an immunodominant conserved antigen. Patients with Corynebacterium jeikeium septicemia or endocarditis have antibody to the 52 Kd breakdown product. The protein cross-reacts with a peptide antigen KVIRKNIVKKMIE (see SEQ ID No. 1) using a mouse monoclonal antibody against the peptide. The stress protein is useful for improved diagnosis, monitoring and treatment of Corynebacterium infections and diseases.Type: GrantFiled: March 22, 1995Date of Patent: March 21, 2000Assignee: The Victoria University of ManchesterInventor: Peter James Burnie

Patent number: 6031804Abstract: An apparatus and method for detecting and replacing a defective sector on an optical disk. Recording data and error correction data are recorded on an optical disk at a manufacturing time or an initial time. The recorded data and the error correction data are reproduced in units of one sector. A defective sector is determined when address data in an address field cannot be reproduced or when a number of errors in at least one sector exceeds a specified value. Address data of the defective sector is recorded in a defect list on the optical disk. Recording data and error correction data are successively recorded on the optical disk in a plurality of successive block areas. Defective sectors are skipped and recording data and error correction data are recorded in a unit of one block beginning in a next sector area.Type: GrantFiled: December 10, 1998Date of Patent: February 29, 2000Assignee: Kabushiki Kaisha ToshibaInventor: Mikio Yamamuro

Patent number: 6032042Abstract: A cellular radio network including mobile radio stations is provided in which at least some of the mobile radio stations are capable of moving in a primary network, and in at least one other network having a location area configuration different from that of the primary network. The user can manually prevent all location updatings and location updating attempts between the different networks and, thus, temporarily "lock" the use of the mobile station within a particular network. Not even an location updating attempt into a "foreign network" is made. It is up to the user of the mobile station to decide when the user activates the registration function. The locking function remains activated until deactivation by the user. Subsequent to the deactivation, location updatings between the networks are performed in a normal manner.Type: GrantFiled: May 1, 1995Date of Patent: February 29, 2000Assignee: Nokia Telecommunications OyInventor: Hanna-Maria Kauppi

Patent number: 6029150Abstract: A method of payment in an electronic payment system wherein a plurality of customers have accounts with an agent. A customer obtains an authenticated quote from a specific merchant, the quote including a specification of goods and a payment amount for those goods. The customer sends to the agent a single communication including a request for payment of the payment amount to the specific merchant and a unique identification of the customer. The agent issues to the customer an authenticated payment advice based only on the single communication and secret shared between the customer and the agent and status information which the agent knows about the merchant and/or the customer. The customer forwards a portion of the payment advice to the specific merchant. The specific merchant provides the goods to the customer in response to receiving the portion of the payment advice.Type: GrantFiled: October 4, 1996Date of Patent: February 22, 2000Assignee: Certco, LLCInventor: David William Kravitz

Patent number: 6023618Abstract: The charging criteria for determining the price for a call between two subscribers in a cellular mobile telephone network, is improved. One cell, or a group consisting of several cells, is chosen as a group of special cells. Upon establishing a call, a mobile switching center of a calling subscriber analyzes whether the location cell of the calling subscriber and/or that of the called subscriber are members of a group of special cells. If this is the case, the charging criteria determined for the group will be applied. Additionally, private branch exchanges may also be connected to the mobile switching center.Type: GrantFiled: June 23, 1997Date of Patent: February 8, 2000Assignee: Nokia Telecommunications OyInventors: Risto Janhonen, Markku Tuohino, Erkki Ojala

Patent number: 6016337Abstract: The invention relates to a method and arrangement for televoting in an intelligent network. In the method, (a) a point (SCP) comprising a service control function SCF sends a televoting activation request to a point (SSP) comprising a service switching function SSF; (b) the point comprising the service switching function SSF counts the calls made by the users of the telephone network to predetermined telephone numbers; and(c) information on the number of calls is forwarded to the service control function SCF of the intelligent network. In order that faultless televoting in a multi-SCP environment could be guaranteed, the point comprising the service switching function SSF makes comparisons, upon receiving a televoting activation request, to find out whether a televoting process activated by some other service control point and using the same or some of the same telephone numbers is in progress, and if so, the point comprising the service switching function SSF does not start a televoting process.Type: GrantFiled: October 10, 1997Date of Patent: January 18, 2000Assignee: Nokia Telecommunications OYInventor: Mika Pykalisto
