IPC: B29D11/00
Filed: 1997-04-04
Abstract: In an injection step, actual injection speed V is closed-controlled so that the actual injection speed V becomes equal to first or second preset speed V1 or V2 while comparing the actual injection speed V with the first or second preset speed V1 or V2 in the section between S0 and S1 from the time when injection of molten resin is started up to the time when the molten resin reaches this side of a gate portion 46 or the section between S1 and S2 from the time when the molten resin reaches this side of the gate portion 46 up to the time when the molten resin reaches the inside of a cavity 3. The injection speed V is open- controlled to third preset speed V3 in the section between S2 and S3 from the time when the molten resin reaches the inside of the cavity 3 up to the time when injection of the molten resin is completed. Because a high injection speed can be secured and an injection speed change can be decreased, it is possible to decrease the frequency of a feed history appearing on the surface of a molded product.

Title: Source traffic control method in atm network to prevent serious local congestion
Inventor: IKEDA CHINATSU
IPC: H04L47/629
Filed: 1997-05-14
Abstract: In an ATM network, a source end system is connected through multiple virtual channels to destination end systems to exchange resource management (RM) cells at periodic intervals and transmit data cells at allowed cell rates (ACRs) respectively set for the virtual channels. The source end system transmits a forward RM cell through an associated virtual channel, and determines a sum of ACR values of the virtual channels in response to receipt of a backward RM cell through the associated virtual channel and compares the sum of ACR values with a predetermined capacity of the access link. The source end system resets a current ACR value of the associated virtual channel equal to a lower-than-previous value when the sum of ACR values is in excess of the predetermined link capacity. In one embodiment, the sum of ACR values is divided by the predetermined link capacity to produce a link load value and the ACR value is reset according to the link load value.

Title: Method and apparatus for adaptive line enhancement in coriolis mass flow meter measurement
Inventor: BOSE TAMAL
IPC: G01F1/84
Filed: 1996-07-03
Abstract: An apparatus and method for determining frequency and phase relationships of vibrating flow tubes in a Coriolis mass flow meter. Adaptive line enhancement (ALE) techniques and apparatus are used in a digital signal processing (DSP) device to accurately determine frequency and phase relationships of the vibrating flow tube and to thereby more accurately determine mass flow rate of a material flowing through the mass flow meter. In a first embodiment, an adaptive notch filter is used to enhance the signal from each corresponding sensor signal on the vibrating flow tubes. In a second embodiment, a plurality of adaptive notch filters are cascaded to enhance the signal from each corresponding sensor signal. In both embodiments, an antialiasing decimation filter associated with each sensor signal reduces the computational complexity by reducing the number of samples from a fixed frequency A/D sampling device associated with each sensor signal. Computational adjustments are performed to compensate for spectral leakage between the fixed sampling frequency and the variable fundamental frequency of the vibrating flow tubes. Despite this added computational complexity, the present invention is simpler than prior designs and provides better noise immunity due to the adaptive notch filtration.  Heuristics are applied to the weight adaptation algorithms of the notch filters to improve convergence of the digital filters and to reduce the possibility of instability of the filters interfering with mass flow measurements.

Patent CA-2210123-A1 (CA)
Title: Absolute optical frequency calibrator for a variable frequency optical source
Inventor: CLICHE JEAN-FRANCOIS
IPC: G01J3/28
Filed: 1997-07-09
Abstract: Arrangements are disclosed for the automatic absolute frequency calibration of a variable frequency optical source using an optical filter,  such as gas cell   or   a   calibrated   interferometer,   providing resonances at known frequencies in the tuning range of the source.   The above calibration is performed by a control  unit  which  has  a  knowledge  of  the  known transmission pattern of the optical filter.  This unit scans  the  frequency  of  the optical  source  via  a frequency control signal over a frequency range and measures the optical intensity of the optical source output light after it has passed through the optical filter.    The  measured  transmission  and  frequency control  signal  values  are  processed  and  stored  in memory and constitute a measured absorption pattern. Once acquired for a frequency range,  this pattern is compared to the theoretical  transmission pattern of the  optical  filter.    Correspondences  are  made  to identify the transmission features against their known counterparts.   A relationship between the  frequency control  signal  and actual  frequency of  the  optical source is established.   The frequency calibration of the  optical  source  over  many  frequency  points  is therefore  achieved.    The  disclosed  arrangement  is especially  suited  to  the  frequency  calibration  of tunable  laser sources,  such as  semiconductor  lasers and   external   cavity   lasers.      Four   specific applications  of  this  absolute  optical   frequency calibrator  are  disclosed.    The  first  one  is  the discrete  ou  continuous  calibration  of  a  variable frequency optical source itself. The second one is the automatic  and  unambiguous  locking  of  the  optical frequency source relative to a selected transmission feature of the optical filter. The third application is the optical frequency measurement of a non-tunable optical  source  using  a beat  note  technique  with  a previously frequency-calibrated  variable  frequency optical   source.   The   fourth  application  is   the frequency  control  of  an  optical  source  using  the frequency measuring technique proposed in the  third application.

Patent CA-2214695-A1 (CA)
Inventor: DUBREUIL LOUIS
IPC: E21B7/00
Filed: 1996-03-15
Abstract: A multiple trepan boring device (D, D') for producing substantially large cuts (C) in large works (W), such as concrete dams, comprises a drilling shaft (24) adapted to be translationally displaced along its longitudinal axis and carrying a series of spaced apart cylindrical rotatable trepans (30) each having a peripheral cutting surface (32) and an annular cutting surface (34, 69), the latter extending in plane perpendicular to the axis of the drilling shaft (24) and radially between the shaft (24) and the peripheral cutting surface (32). Weights (40) apply continuous downwards forces on the shaft (24) and thus on the trepans (30). With the trepans (30) resting on the top of the work (W) to be cut, the trepans (30) are rotated in place, and under the aforementioned forces the peripheral cutting surface (32) of each trepan (30) bores a hole until the drilling shaft (24) rests on the top of the work (W).  Then the shaft (24) is displaced translationally while the trepans (30) continue to rotate thereby causing the annular cutting surfaces (34, 69) to remove a layer of the work (W) extending between the shaft (24) and the peripheral cutting surface (32). This procedure is repeated so as to produce a cut (C) of a width corresponding to the outside diameter of the trepans (30) by successive removal of crescent-shaped layers from the work (W). After the removal of each layer, the shaft (24) is lowered along a distance corresponding to the difference in radii between the drilling shaft (24) and the trepans (30).

Title: Low nox burner
Inventor: BECKER HENRY A
IPC: F23D14/22
Filed: 1996-05-24
Abstract: A burner for the combustion of fuel and air in an industrial furnace, for use in connection with preheated combustion air, is provided having an equal number of evenly spaced air jets and fuel jets. The air jets and fuel jets are discharged so that they initially diverge away from one another, but eventually, the fuel jets are entrained by the air jets. During the course of their trajectories, before meeting, the air jets and fuel jets entrain resident furnace gases which results in heavy dilution of the fuel and air before combustion. The dilution causes off-stoichiometric combustion conditions and results in a lower flame temperature. This is similar in effect to external flue gas recirculation. As well, the fuel jets undergo pyrolysis in the course of their trajectories before entrainment occurs. This creates a reducing zone in which the NOx in the resident furnace gases being entrained is reduced, in part, back to molecular nitrogen. NOx emissions from such a burner are shown to be well below that of conventional burners.

Title: Computer system for creating semantic object models from existing relational database schemas
Inventor: KROENKE DAVID
IPC: G06F12/00
Filed: 1996-06-03
Abstract: A computer system for creating a semantic object model from an existing relational database schema. The computer system analyzes the catalog information of the relational database schema and creates a semantic object for each table defined in the catalog. For each column defined with a table, a simple value attribute is added to the semantic object created for the table.  The system then analyzes the relationship information stored in the catalog to create object link attributes that define relationships between two or more semantic objects as well as to create multivalued group attributes and multivalued, simple value attributes. If the database catalog does not include the relational information, the user is prompted to indicate related semantic objects.
