Filed: 1995-07-21
Abstract: A connecting member includes a substantially spherical core and solder covering the core.  A first substrate has a first pad on the lower surface and a through-hole at the position of the first pad.   A second substrate has a second pad on the upper surface.  A solder paste is provided on the second pad of the second substrate.  The connecting member is positioned on the solder paste.  The first substrate is positioned so that the first pad faces the connecting member.  The connecting member and the solder paste are heated at a temperature so that the core does not melt.  The solder paste and the solder of the connecting member melts to connect the first and second pads.  The solder paste and the solder of the connecting member flows into the through-hole.  A faulty connection can be detected by confirming whether at least a portion of the solder paste and the solder of the connecting member is protruding from the through-hole of the first substrate.

Patent CA-2162099-A1 (CA)
Title: Contactless test method and system for testing printed circuit boards
Inventor: SOIFERMAN JACOB
IPC: G01R31/02
Filed: 1995-11-03
Abstract: A method and apparatus are disclosed for testing unpopulated and inactive populated printed circuit boards for manufacturing defects.  The method and apparatus do not require electrical contact with the board under test.  The method and apparatus include an AC source, which is connected to the stimulator(s).  The stimulator(s) radiate an electromagnetic field onto the traces and components on the board under test and this interaction establishes a potential gradient along the traces and components as the BUT is scanned.  A sensor array is located adjacent to a stimulator (if only one is used) or between a pair of stimulators (if a dual arrangement is used) and detects the displacement currents flowing from the board under test.   The sensors and stimulator(s) do not electrically connect to the board under test, which is positioned between a ground reference plane and a sensor/stimulator unit.  By scanning across the entire surface of the board under test, a displacement current signature of the board under test is obtained.  Manufacturing defects on the board under test are found by computer analysis of the displacement current signature.

Title: Subtitle encoding/decoding method and apparatus
Inventor: TSUKAGOSHI IKUO
IPC: H04N19/146
Filed: 1996-03-18
Abstract: Encoding and decoding of subtitle data is performed in real time. A buffer regulates a flow rate of the subtitle data to ensure that the appropriate subtitles are superimposed with the correct video picture. In encoding, subtitles are generated in correspondence to a video picture. The subtitles are separately encoded and multiplexed with the video picture for transmission. Upon decoding, the subtitles are selected at a time which corresponds to the display of the corresponding video picture. Since the subtitles are processed separately from the video data, the subtitles may be manipulated with great control; thus providing more flexibility in encoding and decoding.

Title: Efficient processing of nmr echo trains
Inventor: PRAMMER MANFRED G
IPC: G01R33/46
Filed: 1994-12-07
Abstract: A method and apparatus (28) is disclosed for efficient processing of NMR echo trains (fig.3) in well logging. A priori information about the nature of the expected signals is used to obtain an approximation of the signal using a set ofpre-selected basis functions (fig.5). A singular decomposition (SVD) is applied to a matrix incorporating information about the basis functions and is stored off-line a memory. During the actual measurement, the apparatus estimates a parameter related to the SNR of the received NMR echo trains and uses it to determine a signal approximation model in conjunction with the SVD of the basis function matrix. This approximation is used to determine in real time attributes (fig. 8) of the earth formation being investigated.

Title: Heat exchanger
Inventor: LANG Y JOSTEIN
IPC: F28F5/00
Filed: 1995-05-05
Abstract: A heat exchanger has been developed with a helical insert (9) perma-nently mounted in a housing (2). Between the windings in the insert (9) there isformed a helical channel (20) for one heat exchange medium. The insert (9) is designed with a channel (10) for the second heat exchange medium. The heat exchanger is designed with a central tube (13) which is axially movable and rotatable. The central tube (13) is designed with scraper elements for removal of deposits in the channel (20). In one embodiment the scraper element is formed by a helical insert (15) of the same design as the insert (9). The insert(15) is designed with a channel (16) for the second heat exchange medium. In a further embodiment the central tube (13) is designed with one or more scraper arms (23) which may be liquid-cooled. Deposits are often formed on the heat transfer surfaces. A cleaning cycle is performed by means of axial movement of the insert (15) which is mounted on the central tube (13) towards the permanently mounted insert (9), thus causing the heat transfer surfaces to touch each other. A rotating movement is then performed, e.g. a part of a turn, while the surfaces are close to each other or in contact with each other, thus causing the deposits on the two surfaces to be rubbed or scraped off and thereby cleaning the channel (20).
