Title: Non-contact photothermal method for measuring thermal diffusivity and electronic defect properties of solids
Inventor: MANDELIS ANDREAS
IPC: G01R31/265
Filed: 1994-06-22
Granted: 2001-03-27
Abstract: There is provided a method of measuring thermal diffusivity of solids and electronic lifetimes and defect properties of semiconductors useful for in-situ, non-destructive monitoring of engineered materials and electronic substrates.  The method, termed photothermal rate window method, involves irradiating a sample with a repetitive square laser pulse of duration Tp and period T0 and monitoring the temperature profile by measuring the photothermal signal emitted from the sample. The period T0 of the repetitive heating pulse is maintained constant and the pulse duration Tp is varied in the range between 0 and T0 with the temperature measured at each value of Tp. The method of measuring semiconductor recombination lifetimes involves irradiating a sample and scanning one of either the period T0 and the pulse duration Tp of the repetitive laser pulse with the other held constant. The photothermal signal emitted from the surface is measured.  Defect energy states in semiconductors are measured by irradiating the sample with a repetitive laser pulse of duration Tp and period T0 (both fixed) and monitoring the photothermal signal as the sample temperature is scanned. Defect levels are correlated with extremum in the profile. The photothermal signal in all the foregoing methods is input into a lock-in amplifier which measures the fundamental Fourier component of the signal. The output of the lock-in amplifier is fitted to a theoretical model of the photothermal response of a repetitively irradiated sample to obtain the thermal diffusivity, or the recombination lifetime.

Abstract: A new drill stem test apparatus and corresponding method includes a dual coaxial coiled tubing adapted to be disposed in the wellbore. The dual coaxial coiled tubing includes an inner coiled tubing, and an outer coiled tubing surrounding and enclosing the inner coiled tubing and forming an annular space which is located between the inner coiled tubing and the outer coiled tubing. The annular space is adapted to contain a pressurized kill fluid. A first end of the outer coiled tubing is sealed by a sealing element to a first end of the inner coiled tubing, the end of the inner coiled tubing extending beyond the sealing element and adapted to receive a formation fluid. The first ends of the inner and outer coiled tubing are disposed in a wellbore. A second end of the inner and outer coiled tubing is wound onto a coiled tubing reel and is connected to a kill fluid valve and a formation fluid valve. When the kill fluid valve opens while the formation fluid valve is closed, a pressurized kill fluid fills and pressurizes the annular space between the inner and outer coiled tubing. While the kill fluid valve is still open, the formation fluid valve is opened. A formation fluid begins to flow from the formation through the inner coiled tubing and through the formation fluid valve. If the inner coiled tubing forms a hole and begins to leak formation fluid, the pressurized kill fluid in the annular space will prevent the formation fluid in the inner coiled tubing from leaking out of the interior of the inner coiled tubing and into the annular space.

Inventor: HAN TAEK-SOO
IPC: H04N5/783
Filed: 1995-10-02
Granted: 2003-07-29
Abstract: A data recording and/or reproducing method for performing a trick play in a digital video tape recording and reproducing apparatus for recording and/or reproducing an advanced television (ATV) signal is performed such that the data area of a sync block each forming audio sector and video sector in a track is divided into a first area and a second area to record and reproduce normal-play data and trick-play data for a normal play and a trick play, respectively. The area corresponding to 5.6 Mbps is used for trick-play data in the case of an ATV signal and a separate data area for the error correction coding of a trick-play data is not necessary. Also, since trick plays of speeds of even-number times are available within the range of the maximum multiple speed, a diversity of speeds of a trick mode is allowed.

Granted: 1999-10-05
Abstract: The  method  is  used  to  create  a  virtual  public numbering domain, which will coexist with and be parallel and non-intrusive  to  the  existing  geographic  North  American telephone network numbering plan.   It will have capacity to provide additional and more flexible numbering resources which will stimulate and enable many new service applications.   The existing   telephone   network   infrastructure   has   digital switching points and a database system.   The method consists in receiving at one of the digital switching points a called number, and verifying whether the number called is a number of the virtual public dial plan.   If the number called is  a number of the virtual public dial plan, the next steps consist of forming with the number called a virtual public address of predetermined length, supplying the virtual public address to the database system to determine a corresponding network node address,  and  to supplying  the  corresponding  network  node address to the digital switching point and routing the call through the network infrastructure according to the existing dial plan.   If the number called is a number of the existing dial   plan,   the   call   is   routed   through   the   network infrastructure according to the existing dial plan and the number called.

Patent CA-2170858-C (CA)

Granted: 2000-02-22
Abstract: A casting method is disclosed in which a resin core  is fabricated by  using a resin which maintains  a  mechanical strength  satisfying  a shape accuracy required for  a  cast product until solidification of molten metal in contact with the  core  and  is  softened when  heated  beyond  the  core temperature  at which the molten metal in contact  with  the core was solidified.  The removal of the resin core from the cast product after the cast product containing the core from a die, includes a step of forcedly cooling the cast  product containing  the core down to a predetermined temperature  at which  the resin core can be removed from the  cast  product without being broken apart by pulling one of its ends, and a step   of   withdrawing  the  core  at   the   predetermined temperature  from  the  cast product  having  been  forcedly cooled down.  It is thus possible to cool the core down to a predetermined  temperature  suited for  the  withdrawal  and preclude  the  inconvenience that the core being  pulled  is broken apart.
