Patent EP-0034851-A2 (EP)
Inventor: SCHOFIELD JOHN
IPC: H03H9/64
Filed: 1981-02-06
Abstract: A surface acoustic wave bandpass electrical filter consists of input and output interdigital transducers (IP, OP) with an interposed track changing multistrip array (MSA). A conventional broadband array (MSA) is divided into two sub-groups of strips with respect to a centre of symmetry (C) separated by different distances along the input track (T1) and the output track (T2) such that the amplitude-frequency response of the array (MSA) has a stopband centred on a predetermined frequency. If the input and output transducers (IP, OP) both have a double electrode configuration, electrode separation λo/4, providing a fundamental passband at a corresponding frequency fo and an equal amplitude passband at the third harmonic 3fo, then a separation difference of λo/6 between the sub-groups of the array (MSA) in the two tracks (T1, T2) can suppress the third harmonic passband in the filter output. The multistrip coupler may instead be divided into three sub-groups (Figure 5). The sub-groups of the multistrip array may be further sub-divided to suppress more than one frequency (Figure 7). Also a multistrip array arranged in groups to provide a shaped bandpass response may have each group divided into sub-groups to suppress a selected harmonic passband of the array (FigureS).

Abstract: The drive circuit for an electromagnetic actuator for the impact element in a printer includes a series circuit of a drive transistor and of a switching transistor there being a reference resistor interposed which together with a Zener diode serves as a current limiter for the current through the drive transistor and the electromagnetic element. The two transistors are controlled in that each of the base electrodes is serially connected to the emitter collector path of a control transistor and the two control transistors in turn are connected to monostable multivibrators which are triggered concurrently but furnish pulses of different duration such that the switching transistor is turned off before the drive transistor. The current limiting permits utilization of residual electromagnetic energy from the preceding actuation pulse without incurring undue losses.

Abstract: Thin film polarographic gas sensors are described wherein the electrodes are deposited on a flexible substrate. A bilumen monopolar catheter-type sensor has a thin cathode layer (8) deposited on the wall of one lumen (4), the distal end of which is sealed by a polyurethane plug (10) such that only the outer edge surface of the cathode layer (8) is in contact with a dip-coated permeable membrane (14). The cathode layer (8) extends to the proximal end of the catheter (2) where electrical contact is made with a conductor wire (16) through electrically-conductive epoxy resin (18). When the sensor is employed umbilically or intravascularly, the second lumen (6) may be employed to withdraw samples from the patient or supply fluids thereto. 
     The cathode layer (8) may be deposited on the catheter material in long lengths, which are then subsequently cut to the appropriate length for individual catheter-type sensors.

Abstract: This invention relates to image generation by thermal printing means. 
     Thermal printing means, such as a thermal print head, are employed to raise the temperature of a normally solid, non-tacky material above its melting temperature and provide a latent liquid image area on heat-sensitive substrate. The latent liquid image can then be developed with a dry imaging powder. In a subsequent step, the developed image can be fixed by means of pressure. In the two-step develop- ing/fixing sequence, the substrate bearing the developed image passes through squeeze rolls to fix the image. Sophisticated, expensive steering mechanisms must be used with the squeeze rolls to guide the substrate smoothly through the rolls to prevent the formation of wrinkles and creases in the substrate. 
     The present invention is directed to a process whereby the image areas of the substrate are simultaneously developed and fixed by contacting them, under sufficient pressure, with a dry magnetizable imaging powder that becomes permanently attached thereto. The one-step de- veloping/fixing procedure eliminates the employment of sophisticated steering mechanisms. The process is useful wherever it is desired to generate images from electronic data sources such as computers, facsimile transceivers, chart recorders, teleprinters, etc., and provide such images in essentially permanent form.

Abstract: An interline transfer CCD image sensor includes a plurality of PN junction photosensor elements disposed in a matrixfash- ion. A plurality of columns of shift register are associated with the matrix aligned PN junction photosensor elements. Each CCD shift register includes a plurality of register elements, each of which includes a buried channel connected to a corresponding PN junction photosensor element via a transfer gate as a potential barrier. A register electrode formed on the buried channel is extended toward the corresponding PN junction photosensor element to cover the transfer gate as the potential barrier. Drive signals are applied to the register electrodes to control the charge transfer operation from the PN junction photosensor to the buried channel in addition to controlling the shift operation in the shift register, thereby eliminating the need for channel stoppers for isolating the photosensor elements.
