IPC: H01L21/20
Filed: 1998-03-23
Abstract: There are provided a method of producing an SOI wafer of high quality with excellent controllability, productivity and economy, and a wafer produced by such method.  In the method of producing a substrate by utilizing bonding of wafers, a first substrate member and a second substrate member are mutually bonded and then the second substrate member is separated from the first substrate member at the interface of a first layer and a second layer formed on the main surface of the first substrate member, whereby the second layer is transferred onto the second substrate member.  In the separation, the separation position at the interface of the first and the second layers is ensured by a method of varying the porosity of a porous Si layer, a method of forming an easily separable plane by the coagulation of pores in porous Si, a method of effecting ion implantation to the interface or a method of utilizing a heteroepitaxial interface.

Title: Shared memory management process
Inventor: JOUENNE FRANCK
IPC: G06F9/52
Filed: 1998-04-16
Abstract: The memory management method involves allowing memory access from concurrent tasks. The management operates according to the phase of a transaction. For a read operation a lock, called a hold, is attributed to each variable to be read. If there is no hold assigned the variable cannot be accessed. A pointer to the location of each variable is passed to the process requesting access to allow it atomic access to the value of the variable. A write operation awaits release of the hold on the variable to be written, and if there is a write lock, awaits its release. If a read lock is present, the priorities of reading and writing task are compared, and the lock released if the writing task has a higher priority.

Title: Method and system for genetic programming
Inventor: WORZEL WILLIAM P
IPC: G06N3/12
Filed: 1996-03-01
Abstract: The invention is a computer-implemented method and system for solving a programming problem using genetic programming techniques. A fitness function measures the relative superiority of a first solution with respect to a second solution. The genetic programming system creates multiple program gene strings containing graph reduction operators. Each program gene string represents a potential solution to the programming problem being solved. Input data is applied to each program gene string to generate a solution for each gene string (60). Each program gene string is evaluated by comparing the solution to the fitness function (62). The program gene strings are evolved based on the evaluation of their fitness (66-84). The gene strings are repeatedly evolved until a termination criteria has been satisfied (64).

Title: Microbiological cell processing
Inventor: BROOKS ROBERT CECIL
IPC: C12N1/06
Filed: 1999-06-04
Abstract: Cell lysis may be brought about by contacting a suspension of cells with a lysis reagent such as sodium hydroxide solution; subsequent treatment enables organic molecules such as plasmid DNA to be separated from other cell components. Intimate mixing of the cell suspension with lysis reagent is achieved by passage through a fluidic vortex mixer (18) arranged so the residence time of the cell suspension in the mixer (18) is less than the time for lysis to be completed, and may be less than 0.1 seconds. Such a vortex mixer (18) comprises a cylindrical chamber with an axial outlet duct and at least one tangential inlet duct, but with no internal baffles. The low shear stress to which the cell suspension is subjected minimizes loss of product through denaturation or fragmentation of the product, and indeed of contaminants. The subsequent treatment may also utilise a fluidic vortex mixer (32).

IPC: A61N5/06

Abstract: In apparatuses and methods for the medical treatment of hyperbilirubinemia, it is known to use phototherapy lamps in a manner that exposes the patient to an essentially steady stream of light. Even the "intermittent" variety of known phototherapy methods are characterized by steady exposure to light whereby the light remains continuously on during their relatively long "lights-on" segments of treatment, such a continuously-on segment lasting on the order of many minutes to several hours. In this invention, however, light is delivered to the patient instead in burst pulses greatly shortened in duration, down to tiny fractions of a second, to approach the mere nanoseconds-long time period actually required to cause the molecular-level therapeutic photoisomerization of bilirubin. Such flashes of light are then repeated only often enough to accommodate or match the actual bilirubin migratory rates of the particular tissue being targeted. The short-duration flashes spaced in time as far apart as possible in sequential cycling can thus reduce to a minimum total light irradiance dose, therefore helping to minimize the potential for phototoxic side effects. This in turn allows the use of greatly increased intensity of light for deeper penetration into patients' target tissue to allow a greater number of bilirubin molecules to simultaneously undergo molecular photoisomerization, all to the therapeutically advantageous effect of more rapid lowering of serum bilirubin levels. Even with such use of greatly-increased intensity of light, actual total irradiance dose to the patient can in fact still remain lower than with previously known phototherapy approaches since the invention so unprecedently eliminates exposure during strategic, extensive 'blackout' periods which the Applicant has discovered as being unnecessary for coverage by light exposure given the actual relationship of required time periods of bilirubin molecular geometric structure alteration by photoisomerization and bilirubin migration in target tissue. The light source used can be of virtually any safe type that includes in its emission sufficient energy levels in the appropriate wavelength range, while specifically a xenon flash tube embodiment would allow for particularly efficient electronic flashing of the light and also possesses the property of yielding a therapeutically optimal output emphasis around the blue wavelengths portion (400 to 500 nanometers) of the visible spectrum. In another embodiment based more on traditional phototherapy light sources, the short-duration flashes can be produced by various mechanical shutter or electrical means. Light delivery to relevant tissue in the patient can be accomplished by any of various external, internal, or surgical means.
