Title: Axial lead electronic part and circuit board mounting it
Inventor: NEGISHI MAKOTO
IPC: H01G13/00
Filed: 1999-08-10
Granted: 2001-06-23
Abstract: The present invention provides an axial electronic part wherein terminals 11 of a chip electronic part element are covered by the tubular metal cap and spread by resin 3. When heating the substrate for soft soldering, the resin is expanded and the soft soldering material that forms the plating layer 12 on the terminals 11 flows along the body 10 and in the gap of the resin 3. Because the two terminals 11 are close, the electrical performance of the capacitor is changed. In the solution of the present invention, an extra metal layer 23 is provided on the inner circumferential surface at the tubular part 22 of the metal cap 2. When the resin 3 is expanded, because the soft soldering material of the extra metal layer 23 flows on the external side of the tubular part 22, the expansion of the resin 3 does not influence the plating layer on the terminals.

Title: Use of zeta potential during chemical mechanical polishing for end point detection
Inventor: KRUSELL WILBUR C
IPC: B24B37/013
Filed: 2000-01-15
Granted: 2001-07-11
Abstract: A technique for utilizing a sensor to monitor fluid pressure from a fluid bearing located under a polishing pad to detect a polishing end point. A sensor is located at the leading edge of a fluid bearing of a linear polish, which is utilized to perform chemical-mechanical polishing on a semiconductor wafer. The sensor monitors the fluid pressure to detect a change in the fluid pressure during polishing, which change corresponds to a change in the shear force when the polishing transitions from one material layer to the next. In order to ensure that there is a noticeable difference in the shear force variation at the polishing end point, a slurry having a particular pH level is selected. The pH level ensures that the zeta potential changes noticeably from one material to the next, so as to induce a change in the shear force, which is detected by a change in the fluid pressure.

Abstract: A PGNAA method provides the nondestructive assay of a homogeneous or a non-homogeneous contaminant (50), such as a hazardous RCRA metal, in a container (36), such as sealed 55 gallon waste drum (36). The method includes employing an interrogation chamber (40) having a wall (42) made of a neutron-reflecting material; and disposing a platform (30) within the interrogation chamber (40). At least one of rotating (31) the platform (30), and elevating (32) the platform (30) is employed. The method also includes disposing the container (36) on the platform (30) and within the interrogation chamber (40); and employing at least one neutron source (46) between the wall (42) of the interrogation chamber (40) and the container (36). The container (36) is irradiated with a fast-neutron burst (44) from the neutron source (46) or as reflected by the wall (42). The fast-neutron burst (44) is characterized by a duty cycle and is thermalized and/or moderated by the container (36), with thermal neutrons (52) reacting with the container (36) and thereby effecting an emission of thermal-neutron induced gamma radiation (54) from the container (36). Gamma radiation data is acquired (10, 11) indicative of the number or intensity of gamma rays and energies of the gamma rays during a predetermined time interval. The acquiring step includes a separate identification of thermal neutron-induced gamma rays, and the gamma radiation data is acquired over only a fraction of the duty cycle. The gamma radiation is analyzed (14, 15, 16) to detect the presence and determine the amount of the non-homogeneous contaminant (50) in the container (36).

Title: Method and apparatus for channel optimization during point-to-point protocol (PPP) session requests
Inventor: REZAIIFAR RAMIN
IPC: H04W36/12
Filed: 2001-04-17
Granted: 2005-04-11
Abstract: A method and apparatus for requesting PPP instances from a packet data services network includes a mobile station configured to send an origination message to a packet data service node (PDSN) at which it has arrived upon leaving the vicinity of another PDSN. The message informs the new PDSN of the new location of the mobile station and indicates both the number of dormant PPP instances associated with the mobile station and a service reference identifier for each such PPP instance. A flag within the message may be used to indicate whether the PPP instances are dormant (i.e., whether the mobile station is engaged in a call). Communications channel resources of packet data services nodes are optimized by reducing the information included in messages from the packet control function network element to the packet data service node network element, and by reducing the use of Mobile Internet Protocol agent advertisement.

Abstract: There are provided a magnetic head for vertical magnetic recording capable of suppressing noises due to a magnetically soft layer and improving the lowering of efficiency, and a magnetic recording and/or reproducing system using the same. The magnetic head is constructed so that θ2 > θ1 assuming that an angle between a line, which is drawn between the center of a main pole of the recording head and the center of a return yoke of the recording head, and a line, which is drawn between the facing end portions of the main pole and return yoke of the recording head, is θ1, and assuming that an angle between a line, which is drawn between the center of the main pole of the recording head and the center of the return yoke of the recording head, and a line, wherein the center of a math pole of the reproducing head and the center of a return yoke of the reproducing head, is θ2. With this construction, the direction of magnetic fluxes flowing through media during a recording operation is not coincident with that during a reproducing operation, so that it is possible to prevent the generation of Barkhausen noises, which are generated when both directions are coincident with each other, and the lowering of reproducing efficiency.
