Patent EP-0657733-A2 (EP)

IPC: G01N22/00

Abstract: The invention relates to a device and a method for measuring the complex dielectric constant of a material by evaluating the detuning of an RF resonator, caused by the presence of the material. In order to simplify the measuring and evaluation circuits, and in order to allow continuous measurement of a material flow, according to the invention two RF resonators (8, 8') with the same design are present, which respectively have a dielectric solid-state resonator (1, 1') in a housing, with a first conductive section (2, 2') and a second section (3, 3') which allows transmission of AC fields. The two RF resonators are positioned relative to each other in such a way that their conductive housing sections (2, 2') screen them against mutual interference and their sections (3, 3') which allow transmission of electromagnetic fields face the material (10) to be measured. The operating frequency coupled into the two RF resonators and/or the resonant frequencies of the RF resonators (8, 8') are chosen in such a way that, in the absence of the material to be measured, the common operating frequency is located exactly centrally between the resonant frequencies of the RF resonators (8, 8'). On the basis of the measured amplitude values of the RF signals respectively received in the two RF resonators, and the values of their sum and difference, the complex dielectric constant of the material can be determined. It is therefore not necessary to sweep the resonant curves of the RF resonators. <IMAGE>

Abstract: A tri-elemental catalyst on a support that includes a pentasil crystalline zeolite and is suitable for hydrocracking and hydrogenation of aromatics-containing petroleum hydrocarbon feedstocks such as hydrotreated cracked feedstock, virgin feedstock, vacuum distillate, middle distillate, mixtures thereof, and the like, is disclosed. The catalyst is suitable for hydrodesulfurization as well as hydrodenitrogenation, thus the feedstock can contain sulfur and nitrogen in addition to the aromatic components. Hydrocracking and aromatics hydrogenation of the petroleum hydrocarbon feedstocks is accomplished under a relatively wide range of process conditions in plural process zones using the tri-elemental catalyst that contains a catalytically active metal phase constituted by a Group VI-B element, a Group VIII first transition series element and a Group VIII second transition series element. In an upstream zone the catalytically active metal phase is supported on a titania-alumina support containing about 5% to about 30% by weight titania in the support. In a downstream zone the catalytically active metal phase is supported on a titania-alumina-pentasil crystalline zeolite support. The preferred pentasil crystalline zeolite is ZSM-5.

Abstract: An optical disc player wherein an amount of jitter in a write clock (WRCK) as opposed to a read clock (RFCK) is detected by a jitter counter (28), the write clock (WRCK) is counted by a reference counter (29) for a predetermined number of frames, the jitter amount is added/subtracted to/from the count output by an adder/subtractor (30), an offset of a further predetermined number of frames is given to a result of the addition/subtraction to generate a subcode synchronizing signal (GRSCOR) completely synchronized with the read clock (RFCK). The subcode synchronizing signal (GRSCOR) is outputted through an output determining circuit (32) only when a reproduction subcode synchronizing signal (SCOR) is found matching by a match detector (33) with the count output of the reference counter (29) twice successively. The novel constitution can correctly perform sound linking even for software having successive fixed patterns and perform sound linking without error even if reproduction data at sound linking point is processed with previous-value hold or interpolation.

Abstract: The method involves selection of signals from navigation satellites which are received by an antenna (10) on a vehicle at a location. Because of screening by parts of the vehicle, both signals falling directly in the range of the antenna (10) and also reflected signals are received. The latter are sent from navigation satellites outside the range of the antenna. First, the instantaneous drive direction (D) of the vehicle (14) is determined. The range of view (B) of the antenna (1) relative to the vehicle direction (D) is determined. From the signals received by a GPS receiver (22), only those from satellites (1-5) within the instantaneous range (B) of the antenna (1) are selected. Only the selected signals are used to determine the position of the vehicle (14). <IMAGE>

Abstract: A method of forming closely spaced metal electrodes contacting different regions of a semiconductor device is disclosed. The method includes first depositing a sacrificial layer over a developing semiconductor structure. Next, a photoresist layer is deposited over the sacrificial layer and then patterned and developed with a re-entrant profile opening. An opening in the dielectric layer is formed to expose a first semiconductor layer through the re-entrant profile using an anisotropic etch. The photoresist opening is enlarged by removing a portion of the photoresist layer. Then, a metal layer is deposited over the entire structure such that the metal contacts the first semiconductor layer and extends over a portion of the sacrificial layer. The photoresist layer, the sacrificial layer and portions of the first semiconductor layer are removed so that a first metal electrode is connected to a semiconductor region. The first electrode has a lateral extension determined by the amount the photoresist opening is enlarged. The vertical clearance between the first electrode and a second semiconductor layer is determined by the thickness of the sacrificial layer. A second metal electrode is formed by either a conventional lift-off procedure or by a conventional deposition and etch procedure.

Abstract: A resistance measuring circuit (10) generates a predetermined reference voltage and impresses that reference voltage across a squib detonation device (12). The resulting current flowing through the squib is mirrored by a current mirror (42,52,54) for providing multiple mirrored currents. The mirrored currents are compared to known current sources (58,60). The output signals go high or low depending on whether the mirrored currents are greater than or less than the fixed current sources. The output signals provide an indication as to whether the measured squib resistance is within a specified resistance range. The current sources may be precisely matched to maintain high accuracy in measuring the resistance.

Abstract: A frequency error occurring in a repeater station (5) and a receiving side radio station (4, 6-8) is determined by using a dummy signal received from the repeater station, and is stored as frequency control data corresponding to the frequency error into a memory (209). By controlling a reception frequency based on the stored frequency control data, a data signal received from the repeater station is compensated for the frequency error. A relatively large frequency error such as the common frequency error occurring in the satellite (5) and the downconverter (7) of the receiving side can be eliminated effectively.

Abstract: The invention relates to an ink-jet printer which uses an ink containing fine solid particles of a pigment suspended in a carrier liquid. The print head of the printer has an ink ejection orifice at one end of an ink chamber, and the ink chamber is provided with a first electrode to which a first DC voltage is applied for concentrating the pigment particles in the vicinity of the orifice by electrophoresis and a second electrode to which a second DC voltage in pulse form is applied for ejecting an agglomeration of the pigment particles together with a small amount of carrier liquid from the orifice. In the printer the length of waiting time, which elapses from the decay of a pulse of the second voltage, is checked. When the waiting time is relatively long, the polarity of the first voltage is inverted to prevent excessive concentration of pigment particles in or in the vicinity of the orifice, and/or the second voltage is modified to promote movement of pigment particles in the vicinity of the second electrode toward the tip of the second electrode.
