Patent EP-0629993-A2 (EP)
Inventor: BOLORFOROSH MIR SAID SEYED
IPC: H04R17/00
Filed: 1994-06-14
Abstract: An ultrasonic probe having one or more piezoelectric ceramic elements, each having a respective bulk acoustic impedance. Each element has a respective front face and a respective piezoelectric ceramic layer integral therewith to provide efficient acoustic coupling between the probe and a medium under examination by the probe. The respective piezoelectric layer of each element includes shallow grooves disposed on the respective front face of each piezoelectric element. A groove volume fraction of the piezoelectric layer is selected to control acoustic impedance of the piezoelectric layer so as to provide a desired acoustic impedance match between the bulk acoustic impedance of the element and an acoustic impedance of a medium under examination by the probe. Electrodes extend into and contact the grooves, imposing electrical boundary requirements that support a desired electrical field distribution within the element.

Abstract: A method of separating and purifying a spent solvent generated in a nuclear fuel cycle and containing a higher hydrocarbon and a phosphate. This method comprises applying to the spent solvent a pressure high enough for allowing the crystallization of the higher hydrocarbon to thereby crystallize the higher hydrocarbon, and separating under pressure a resulting solid mainly composed of the higher hydrocarbon from a remaining solution containing the phosphate in a higher concentration. The remaining solution may further be subjected to low-temperature vacuum distillation to separate the solution into the phosphate and a deterioration product thereof contained in the solution.

Abstract: In order to generate a solid model from one plan view and one or a plurality of sectional views, input two-dimensional drawing data is classified into plan view data and sectional view data, and closed regions and inclusion relations among the respective closed regions are detected from the classified plan view data. Attributes of the detected closed regions are detected, and the detected closed regions are grouped into groups, each including closed regions of the same attributes based on the detected attributes of the closed regions. The sectional view data is divided on the basis of data on the detected closed regions. Some of the closed regions are three-dimensionalized based on the divided sectional view data. Closed regions not belonging to the three-dimensionalized portion of the closed regions but belonging to the same group as a three-dimensionalized closed region are three-dimensionalized by the same method as was used for the three-dimensionalized closed region. A solid model is generated by combining the three-dimensionalized closed regions through Boolean operations performed on the basis of the inclusion relation among the respective closed regions.

Abstract: After performing high speed sensing with shutting off digit line pair, in which digit line is connected to an objective memory cell for access, only the digit line which is connected to the memory cell is electrically connected to the sense amplifier to perform re-writing of information to the memory cell by the corresponding sense amplifier. In subsequent balancing and pre-charging process, pre-charging is performed after sufficient balance of potential is established in the digit line pairs. By this, no extra charging current will flow in the digit line and/or the pre-charging power source to reduce power consumption.

Abstract: Sample analysis in a portable analytical instrument (100), preferably in the form of a gas chromatograph, benefits from temperature control of one or more thermal zones (108) in the instrument by way of a thermal isolation system (104) that includes a novel pumping assembly (124) to effect a selective amount of thermal isolation of the thermal zone. The pumping assembly includes a pumping element (210) in the form of a tubular or planar palladium structure (502). The pumping assembly (124) makes use of the unique properties of palladium to allow selective control of a nominal gas pressure within a vacuum cavity. A component system (106), which may include a separation column (318) and a thermal device (118) for heating and/or cooling the component system, may be provided within the vacuum cavity. The thermal device (118) and the pumping assembly are individually controlled by a control system (102). The pumping assembly (124) may be operated to allow selective control of the thermal isolation of the thermal zone; alternatively, the component system (106) may be subject to a controlled temperature by operating the thermal device. A sample mixture passing through the separation column (318) may thereby be exposed to a desired temperature profile according to a selected program so that the sample will separate into its components for subsequent detection by a detector (321).

Abstract: An infrared light beam, emitted from an infrared light source 4, arrives periodically and alternatively at a sample cell 1a and reference cell 1b through a rotating chopper 2. The beam, which travels through the sample cell 1a and reference cell 1b, is detected as a sample signal and reference signal by a detector 5. The chopper 2 has apertures 2a and 2a. Since the aperture 2a, which faces the sample cell 1a, and the aperture 2b, which faces the reference cell 1b, are each formed in an arc shape having a central angle of about 90 degrees, the amount of time for which the infrared light beam is emitted and not emitted to the sample cell 1b and the reference cell 1a are all about equal. Therefore, the non-dispersive infrared analyzer can obtain about twice the amount of information about the concentration of the gas to be measured than a conventional apparatus per one chopper rotation.

Abstract: Data sequences (D1 through DL) correspond to L different parameter sets (effective symbol length, guard interval length, the number of carrier waves) and transformed into parallel data by respective serial/parallel converters (111 through 11L), which are allocated to respective carrier waves for OFDM and subjected to inverse discrete Fourier transform by inverse discrete Fourier transformers (121 through 12L) to produce sampled values for the transmission waveform in the time domain. The sampled values are transformed into serial sequences of sampled values by parallel/serial converters (131 through 13L) and then into a single temporal sampling sequence by a temporal sampling sequence switching unit (14). A frame synchronizing symbol is added to the temporal sampling sequence and then transformed into an analog base band OFDM signal before it is converted up to a transmission signal. The frequency bandwidth of the OFDM signal is made smaller than a predetermined value defined by the bandwidth of the available transmission channel. As a result, an OFDM signal that can be received well regardless of the mode of reception can be transmitted.

Abstract: A light radiated from a light source is divided by a grating into a main beam for detecting information signals and sub-beams for tracking, and thus irradiates a mini disk. The beams reflected by the mini disk are converged through a concave cylindrical mirror on a second light detector composed of adjacently disposed divided light receiving elements H (light receiving parts A and B) and J (light receiving parts C and D) and light receiving elements E1, F1, E2 and F2. The concave cylindrical mirror shapes the reflected beams so that spots of the reflected beams converged on the second light detector take elliptic shapes that are flattened in a direction in which the main beam for detecting the information signals and the sub-beams for tracking are arranged. In this manner, reliability of an optical head can be improved without increasing the size of the light receiving elements and without causing interference between a main spot and sub-spots.
