Title: Hot/dry, hot/moist or cold therapy pad
Inventor: MCSYMYTZ LAURIE L
IPC: A61F7/08
Filed: 1991-09-11
Abstract: HOT/DRY,HOT/MOIST OR COLD THERAPY COLD PAD          ABSTRACT OF THE DISCLOSURE             A  therapeutic  pad  is  formed  from  a  container having elongate compartments arranged in parallel relationship across the width of the container and extending substantially across  the  full  length of  the container.   The container is formed from a fabric material which is permeable to moisture but  contains  the  filler  material  which  is  sand.    The compartments are filled with the sand.  The use of sand allows moisture to be applied to the container which will then be held within  the  interstices  of  the  sand  for  either  heating  by microwave or cooling by freezing.  A separate cover is formed from a quilted padded fabric material shaped to double the size of the container so that it can be folded to cover both sides of the container.   One half of the cover includes a moisture impermeable layer to prevent the escape of moisture from that side while the other side allows the escape of moisture.  This allows  the user choice of applying either moist heat or dry heat to the body of the patient.

IPC: H03K4/502
Filed: 1991-09-25
Abstract: ABSTRACT            Disclosed are a constant current circuit which pro-vides an output current I2 which varies with changes of power source voltage Vcc, and an oscillating circuit whose oscillation frequency varies with changes of I2 in the constant current circuit.  The constant current circuit comprises bipolar transis-tors coupled to form a differential amplifier, wherein one of the transistors is supplied with a reference voltage and another is supplied with a divided voltage of Vcc, and a resistor connecting the emitters of the transistors is provided for controlling the slope of the Vcc-I2 characteristic curve of the constant current circuit.  The oscillating circuit comprises a capacitor charged with I2 and a switching means for discharging the capacitor when it is closed and a voltage detecting means operating to close or open the switching means according to the voltage detected at an end of the capacitor.  Thus, the switching means cycles on and off to generate pulses with a frequency depending on I2 and hence depending on Vcc.  Methods for controlling the frequency range of the oscillating circuit and the rise time to fall time ratio of the pulses by introducing additional constant current supplying sources are also disclosed.

Title: Method of fabricating a field-effect transistor
Inventor: VAAN SCHRAVENDIJK BART J
IPC: H01L29/78
Filed: 1991-10-15
Abstract: PHA 1208                                        04.10.1991 ABSTRACT: A method of fabricating a field-effect transistor.     In manufacturing a field-effect transistor structure, opposite-conductivity impurities are introduced into a semiconductor region (14) to form protection zones (26) and source/drain extensions (24), A shield (20 and 22) prevents the impurities from passing through the underlying section of the upper semiconductor surface (16). A further impurity is introduced into the semiconductor region to form main source/drain zones (34). A larger shield (20 and 32) prevents the further impurity from passing through the underlying section of the upper semiconductor surface. In the resultant FET structure, the final protection zones (26A) are fully surrounded along their lateral and lower surfaces either by the combined source/drain zones (34/24A) or by the combined zones and dielectric material (12). The final protection zones extend slightly under the gate electrode (20). The protection zones in combination with the final source/drain extensions (24A) substantially overcome the hot charge carrier effect.

Patent CA-2064092-A1 (CA)
Inventor: MIKI TORU
IPC: C12N15/16
Filed: 1990-07-30
Abstract: A highly efficient genetic cloning system is disclosed which is particularly useful for cloning cDNA copies of eukaryotic mRNAS and can direct the orientation of inserts in plasmid composite vectors with large cloning capacities. Cleavage of such vector DNA, by the restriction enzyme Sfil, for example, creates two different non-symmetrical 3' extensions at the ends of vector DNA. Using a linker-primer and an adaptor, cDNA is prepared to have two different sticky ends which can be ligated to those of the vector. When the cDNA fragments and the vector DNAs are mixed, both the molecules can assemble without self-circulariza-tion due to base-pairing specificity. This system provides (1) high cloning efficiency (107-108 clones/g poly (A)+ RNA), (2) low background (more than 90 % of the clones contain inserts), (3) directional insertion of cDNA fragments into the vectors, (4) presence of a single insert in each clone, (5) accommodation of long inserts (up to 10 kb), (6) a mechanism for rescue of the plasmid part from a .lambda. genome, and (7) a straightforward protocol for library preparation.

Abstract: An improved method of bonding sand cores to form an assembly, using paste usually containing clay or silicates, the method comprising: (a) coating at least one interfacing surface of intermating core parts with paste in a thickness of about .005-.020 inches; (b) mating the coated interfacing surface of one core part to the other core part to form an assembly; and (c) subjecting the paste in the assembly to microwave energy at an energy level of about 5-7 kilowatts to effectively dry the paste in a manner proceeding first from the interior of the paste body to its outer peripheral extremities.  The subjection to microwave energy draws the core parts closer together by shrinking the paste coating and by causing the paste to boil and drive the paste into pores and/or voids of the intermating core surfaces; such process is preferably carried out within a time period of 10-30 seconds.

Abstract: A mechanism for facilitating metric conver-sion of digitized images intended for use with a multi-resolution, multi-application environment is integrated into the encoding and decoding mechan-isms of the hierarchical database, such that stored residual image files contain metric change informa-tion.  In a preferred embodiment of the invention, the metric conversion operator is executed upon a relatively low spatial resolution file, thereby result-ing in a substantial reduction in processing over-head, as advantage is taken of the availability of the reduced size of the lower spatial resolution base file within the hierarchical database, so that a met-ric conversion may be performed on the relatively small number of pixels within the base file, prior to up-converting the image to a relatively high spatial resolution image, such as a 2048 X 3072 pixel  im-age for driving a high resolution digital thermal co-lor printer.
