Abstract: A catheter (3501), system, and method for selectively ablating prostatic tissue about the prostatic urethra. The catheter includes an elongated member having distal, proximal, and intermediate portions, the intermediate portion being shaped and sized for intimate contact with the prostatic urethra. The distal and proximal portions of the catheter include fixation and cooling balloons (3503,3504) having an annular recess therein for positioning the internal and external sphincters therein and for maintaining the longitudinal position of the catheter in the prostatic urethra. A thermally conducted, heat-emitting element (3502) is positioned in the intermediate portion for producing a thermally conductive heat distribution to ablate the prostatic tissue. The catheter (3501) also includes irrigation and aspiration passageways therein for communicating with the interior of the distal and proximal cooling balloons. A circulating pump of the ablation system circulates coolant through the balloons to maintain the temperature of the sphincters below an injurious temperature. Sensors are positioned about the heat-emitting element (3502) as well as in the cooling balloons (3503,3504) for supplying information to the controller of the system. The controller in response to the temperature information and the energy supplied to the heat-emitting element (3502) controls the supply of energy to the catheter (3501) as well as the pump circulating the coolant.

Abstract: This invention minimizes the number of non-trivial multiplications in the DCT process by rearranging the DCT process such that non-trivial multiplications are combined in a single process step. In particular, the DCT equations for the row-column application of the DCT process on k = pq points wherein p and q are relatively prime, are factored into a permutation matrix, a tensor product between matrices having pxp and qxq points, and a matrix whose product with an arbitrary vector having pq points requires pq - p - q + 1 additions and/or subtractions. The tensor product is then further factored to remove non-trivial multiplications by developing a a first factor having (pq - p - q + 1)/2 non-trivial multiplications and a diagonal matrix. The diagonal matrix is not unique for any set of data. Its j,j-th elements are chosen from a subproduct of the factorization of the tensor product. Once the diagonal matrix elements are chosen the remaining first factor is developed. When the factorization is complete, the diagonal matrix is ab-sorbed into the quantization step which follows the DCT process. The quantization step is the multiplication of a diagonal matrix by the DCT output data. The quantization diagonal matrix is combined with the diagonal matrix of the DCT to form one multiplication process by which non-trivial elements multiply data. This combination of multiplication steps reduces the number of non-trivial multiplications in the DCT process. In addition, the same factorization technique is applicable to the two dimensional direct application of the DCT to an kxk matrix of points. Specifically, the transform matrix on kxk points is defined to be the tensor product of the transform matrix on k points with the transform matrix on k points. This results in the individual factors of the transform matrix on k points forming a tensor product with themselves and demonstrates that the factorization on k points also reduces the number of non-trivial multiplications on the transform matrix on kxk points. In addition, and similarly, the same factorization technique is applicable to to the application of the inverse DCT on k points and to the inverse two dimensional DCT on a kxk matrix of points. Specifically, the inverse transforms are obtained by transposition of the factorization of the forward transforms, because the DCT is an orthogonal operator and hence its inverse equals its transpose. Alternately, the inverse transforms are obtained by direct inversion of the individual factors in the factorization of the forward transform.

Abstract: A disk player has a magazine for storing disks and a disk transport mechanism transporting a selected disk between four positions including an eject position, a load position, a playback position, and a store position which lie in a single plane. The selected disk is carried upon a tray from the eject position to the load position where the selected disk is partially removed from the tray to the playback position above a disk reader. The magazine accepts a plurality of disks. A magazine driving mechanism provides relative movement between the magazine and a plane of transport of the disk transport mechanism permitting a selected disk to be inserted or removed from the magazine at the store position. A disk clamping mechanism moves the disk reader relative to a clamp assembly in order to clamp the selected disk to a turntable. Both the disk clamping mechanism and the magazine driving mechanism are driven from a common drive source. An output of the common drive source is switched by the disk transport mechanism via a planetary gear assembly. An embodiment of the invention optionally provides for transporting the disks upon carriages accepted in the magazine and a lifter mechanism displacing apart disks in the magazine to allow sufficient clearance for access to a selected disk.

Abstract: A spring is wound on a connection terminal with one end thereof fixedly secured to the connection terminal. A spiral protuberance is formed on a bore wall of a holder hole and is engaged with the spring. With this construction, when the connection terminals are to be fitted together, the spring is guided by the spiral protuberance to be angularly displaced, and at the same time, the connection terminal fixed to the spring is also angularly displaced in synchronism therewith. Therefore, even if dust or the like deposits on connection terminals, it can be removed by the rotation of one of the connection terminals during the fitting operation to maintain a good electrical connection.

Abstract: A microwave oven includes a cavity (2) in which food (3) is accommodated, a magnetron (8) for generating microwaves, and a waveguide (7) to supply microwaves generated from the magnetron into the cavity. The waveguide has substantially a truncated cone configuration in which the cross sectional area at the cavity side is greater than the cross sectional area at the magnetron side, and an output antenna (13) of the magnetron is disposed to project from the bottom of the waveguide at the magnetron side into the inner space of the waveguide. The microwave oven further includes a flat radiation antenna (15) fixed in the inner space of the waveguide around the output antenna of the magnetron while maintaining distances from the waveguide and the output antenna of the magnetron in which no spark is generated. Therefore, the radiation area for emitting the microwaves is increased significantly to improve heating nonuniformity within the cavity.

Abstract: Assay for detecting nucleic acid sequence, which comprises the steps: [A] contacting (1) a target single-stranded nucleic acid, (2) a pair of nucleic acid primers having nucleotide sequence complementary to the target nucleic acid and its complementary chain respectively, (3) a fluorescent-labeled nucleic acid probe which has a nucleotide sequence designed so as to be hybridized to the target nucleic acid downstream (at the side of 3'-terminus) from where the nucleic acid primer is hybridized and has a modified 3'-end so that the nucleotide chain is not elongated by a nucleic acid polymerase, and (4) a nucleic acid polymerase having exonuclease activity specific to a double-stranded nucleic acid in the presence of substrates for the enzyme (four kinds of nucleoside triphosphate), and thereby elongating the said nucleic acid primer chain and simultaneously hydrolyzing only the fluorescent-labeled nucleic acid probe hybridized to the target nucleic acid; [B] denaturating the chain-elongated product of primer to a single-stranded form; [C] amplifying the target nucleic acid by repeating the steps A and B; and [D] determining the change in fluorescence polarization resulted by the hydrolysis of the probe. This method is effective to detect the target nucleic acid sequence more simply with higher sensitivity and higher reliability in comparison with known methods, and further has advantages that because of no carryover or contamination of the amplified nucleic acids into subsequent reactions, undesirable false positive result can be avoided.

Abstract: In a technique for recording digital video signals, digital video signals in the form of DCT coefficients, obtained by e.g. discrete cosine transformation, are quantized and compressed so as to be recorded on a recording medium. A first quantization step decision unit (23) determines a quantization step in terms of a video segment made up of plural macro-blocks as a unit so that the quantity of quantized data is less than a pre-set data quantity. A second quantization step decision unit (24) determines a quantization step in terms of the macro-blocks as a unit so that the quantity of quantized data is less than the pre-set data quantity. A quantization unit (25) quantizes the digital video signals with quantization steps determined by the first and second quantization step decision units (23, 24).
