Patent EP-0107059-A1 (EP)
Inventor: ROCHA HENRY ALBERT FERREIRA
IPC: H01L41/107
Filed: 1983-09-24
Abstract: A current sensor, integratable with power switching and control circuitry on a common substrate and insulatable from current-carrying conductors, utilizes a piezoelectric element (14) located between a pair of current-carrying conductors (11, 12). The conductors (11,12) carry a current flowing in the same direction, causing an attractive force therebetween to act upon the piezoelectric element (14) and generate a voltage therein proportional to the square of the conductor currents. Use of a pair of sensors, each in a different portion of a half-bridge circuit, and associated electronics for providing a sensor output proportional to the instantaneous value of the sensed current, is also described.

Abstract: La transmission à ondes de pression comporte une chemise en forme de gobelet destinée à assurer l'étanchéité entre la partie menante et la partie menée de chaque côté du générateur d'ondes de pression (12). La chemise est renforcée à l'intérieur contre les déformations à l'aide d'un corps d'appui (10, 11) en forme de gobelet et ouvert du côté pression.

Abstract: Apparatus is provided for adapting an analog depth sounder for the calling out of the depth at regular time intervals. In one embodiment, a self-contained adapter module is mounted to the face of the depth sounder so as to cover the depth sounder display, with the module including a transparent plate carrying a detector array and with electronics and speaker carried at the center of the array. In this embodiment, the detectors are arranged in thin radially extending lines to permit accommodation to displays of different diameter. Alternatively, small detectors are arranged along a circle having a diameter which overlies at least a portion of the orbiting radiating element which radiates along a considerable length. This alternative array configuration also accommodates a range of display diameters. As a further alternative, to accommodate different diameter displays, the thin line detectors may be replaced with radially extending light pipes with detectors at their ends. The transparent plate with almost invisible detection apparatus permits viewing of the depth sounder display through the plate so that visual as well as audible readout may be achieved. Electronics is provided to decode the angular position of the orbiting element of the depth sounder at the time the element is actuated to provide a digital number representing depth. This number is then used in generating its speech equivalent through a standard speech synthesizer and loudspeaker.

Abstract: A solid-state image sensor has an electrically floating carrier detecting electrode (12) formed on a substrate (10), into which the signal carriers are transmitted, a sense amplifier circuit (14) detecting the variation in a voltage of the electrode (12) at the time of transferring the carriers, and a resetting electrode (RS) for resetting the potential of the electrode (12) to a predetermined potential at every read-out period of the picture element section. A circuit arrangement (36) for removing noise is provided to have two switches (S1, S2) which switch to alternatively become conductive in response to control pulse signals (40-1, 40-2). The first switch (Sl) becomes conductive during a first period within one picture element period. During the first period the CCD output signal contains an effective image signal component. The second switch (S2) becomes conductive during a second period during which the CCD output signal contains a reset noise component, thereby forcibly fixing the level of the reset noise signal to a DC reference potential (Vd) so that reset noise can be removed.

Abstract: A method of ion analysis and detection of weakly dissociated anions or cations in an eluent by first separating such ions on a chromatographic separation medium by ion exclusion chromatography or mobile phase ion exclusion chromatography. The eluent includes an acid or base with a co-ion of the same charge as the ions to be separated, such co-ions being in the hydronium or hydroxide form. In one embodiment the effluent from the separation medium is contacted with one side of an ion-exchange membrane (20) having exchangeable ions of opposite charge to the ionic species. The opposite side of the membrane includes a regenerant with salt-forming suppression ions capable of forming a weakly conducting salt with the co-ions. Then the separated ionic species are detected preferably by a conductivity detector (12). In another embodiment, the membrane is replaced by a resin bed with ion-exchangig sites of opposite charge to the co-ions. There, co-ions form a suppressed salt with the exchangeable ions.
