Title: Condensateur multicouche thermiquement stable

IPC: H01G4/20
Filed: 1989-07-24
Abstract: Les caractéristiques thermiques de chacune des couches (20, 22 et 24) d'un condensateur en céramique multicouche sont réglées (par dopage chimique du matériau diélectrique de base, de façon à en échelonner les caractéristiques thermiques (par exemple les points de Curie). Il en résulte que la caractéristique thermique composite de la structure multicouche est beaucoup plus stable que celle de n'importe quelle couche prise individuellement. Les caractéristiques thermiques des couches individuelles se combinent de façon cumulative, réalisant ainsi l'objectif recherché de capacitance élevée et de stabilité thermique uniforme pour des matériaux qui ont une constante diélectrique élevée mais une stabilité thermique faible. Ainsi, en formulant de façon appropriée la composition des couches d'un condensateur à puces en céramique multicouche, une stabilité thermique relative de la capacitance et une efficacité de capacitance volumétrique élevée sont obtenues.

Abstract: The method is used for distinguishing "offset" direct voltage components of an apparatus for carrying out the method from the direct voltage components generated by direct-current components of the current to be measured, only the former having to be corrected in the determination of Ieff. In method steps, voltages are determined in succession in time which correspond to an "offset" direct voltage of the amplifier apparatus (4; 6; 7; 8), to an "offset" direct voltage of the Hall element (5), to N samples of the current to be measured, to a sum value of the N samples, to a sum value of square values of the N samples, to a total "offset" direct voltage of the apparatus and to a mean value of the current to be measured. The mean value of the current to be measured is then compared with a reference value and Ieff is calculated with the aid of a first formula if the mean value is greater than the reference value, or with the aid of a second formula if the mean value is less than the reference value. The apparatus contains switches (4, 11, 12), a constant-current source (6), amplifiers (7, 8, 9, 10), an analog/digital converter (13) and a computer (14). <IMAGE>

Abstract: An integrated circuit comprises a converter for converting a logic input signal of a first logic type into a logic output signal of a second logic type, for example from ECL to CMOS level. The converter comprises a buffer (10), including a controllable load (14) and a driver transistor (12), and a control circuit (20). In dependence on a control voltage and a reference voltage (V REF ) externally applied, the load (14) is controlled so that the output signal (V OUT ) is substantially equal to the reference voltage (V REF ) if the input signal (V IN ) is substantially equal to the control voltage. The load (14) and the driver transistor (12) in the buffer are controllable in a mutually opposed manner, a capacitance (25) being inserted between the control terminal of the load and the input terminal (16) of the driver so as to pass the AC effect of signal transitions to the load, thus speeding up the transition at the buffer. In one embodiment the control circuit (20) comprises a copy (30) of the buffer (10), which copy (30) receives the control voltage on its input, its load being controlled by a differential amplifier (40) whose inputs receive the reference voltage (V REF ) and the output voltage of the copy. A CMOS-SRAM comprising ECL/CMOS level converters of the above kind communicates with fast ECL circuits and has a low energy consumption.

Title: Method and device for separating liquid and a second substance
Inventor: MIDDELBEEK CORNELIS GERARDUS
IPC: B01D17/02
Filed: 1990-10-04
Abstract: The invention relates to a method for separating at least one liquid, for example water, and a second substance, for instance oil and/or pollutants, from a liquid fluid, for example a suspension or dispersion, by flotation by means of air. 
     According to the invention, a calm flotation zone [55], in which small air bubbles are present, is separated by means of a bell-jar periphery from a rise zone for large air bubbles [52]. Large air bubbles would disturb the separation because they have a strong tendency to rise, whereby they create agitation more than they carry second substance upwards. The large air bubbles enter the bell-jar. The small air bubbles which adhere to particles of second substance result in an adequate flota­tion of these particles in a calm zone.

Abstract: In a sulphuric acid recovery process, wherein the majority of acid is reclaimed and recycled by spray drying a waste acid stream, an improved process for recovering the sulphur content of the metal sulphates. The improved process comprises roasting the metal sulphates to generate metal oxides and a gaseous stream of sulphur dioxide and sulphur trioxide, which gaseous stream is fed to the spray drier to reduce the level of heated make-up air required for spray drying, and for recovery of the sulphur value contained in the gaseous stream. The process reduces the loss of sulphur value and produces a solid metal oxide powder which is easier to dispose.

Abstract: In the method for cutting material, use is made of a laser which is pulsed with a frequency above 1 kHz, the material being removed by the juxtaposition of relatively small bores, and the contour of the path being traversed several times in order to smooth the edges between the individual bores. In a particular exemplary embodiment for producing holes in magnetisable plates for the rotor of micro motors, use is made of a continuous wave laser having an acousto-optical Q-switch cell which is operated at a frequency of 2500 - 3500 Hz, the ratio of the off period to the on period is 250 - 350 : 1, in order to prevent the Curie temperature from being reached in the material. Apart from the YAG neodym continuous wave laser and the acousto-optical Q-switch cell, the device for carrying out the method has a rotatably mounted machining optical system (3), which is driven by a motor (11) and contains a wedge plate (14) and a downstream focusing optical system (5).
