Patent EP-0280230-A2 (EP)
Inventor: CONNERY JAMES G
IPC: G01N27/403
Filed: 1988-02-22
Abstract: There is provided a system for measuring a selected ion in a solution so as to avoid noise pickup from AC parasitic currents and measurement offset from DC parastitic currents, such as are frequently found in pH measurements on low conductivity grounded solutions like high purity water. The system in one form has an operational amplifier with an ion selective electrode connected to its inverting input, a counter electrode connected to its output, and circuit common connected to the non-inverting input, so that the potential of the ion selective electrode is continuously driven to circuit common. The reference electrode of the system is connected to a high impedance measuring circuit for measuring the voltage level of that electrode with reference to circuit common as a measure of the concen­tration of the selected ion in the solution.

Abstract: For the autonomous determination of the course of a land vehicle, a sensor evaluating travelling data can be combined with a sensor evaluating earth magnetic field data. In this manner, the advantages of a short-distance stability of the sensor evaluating travelling data can be combined with a long-distance stability of the sensor evaluating the earth magnetic field data. Particularly advantageous results are obtained if the output signals of the sensor evaluating travelling data are conducted via a high-pass filter and the output signals of the sensor evaluating the earth magnetic field data are conducted via a low-pass filter and the two signals are subsequently added. 
<??>The invention can be used for supplementing a city-map-supported electronic location-finding and navigation system for car drivers.

Abstract: In an invertor, having two transistors (T1, T2), which are connected to a DC voltage (UB) and are controlled to switch on alternately, at the instant of switching on, the response of the transistors is undefined. The invention is intended to avoid this. An additional charging path from the operating voltage (UB) is produced for a bias voltage network (N1) connected to the base of a transistor (T1), preferably by specially switching a symmetry resistor (R2'). Particularly invertors for supplying an inductive cooker plate.

Abstract: A plastic object is manufactured by a process including vacuum metallizing with a corrosion prone metal, namely indium, a dielectric substrate to form "islands" of the indium top coated with a clear resinous layer which encapsulates and insulates the islands, one from another. The indium islands are less than one thousand angstroms thick and have an average diameter of less than three thousand angstroms. The island structure is etched following the growth of the metal as it is deposited between the nucleation stage and the stage of channelization of formation of an electrically conductive film. The etchant is selected to clear channels between island structures to improve adhesion of a dielectric resinous top coat to the dielectric substrate by order of magnitude to adhesion to the islands. 
     A preferred application of this invention is the manufacture of exterior automobile trim components the base structure of which is a flexible elastomer such as a thermoplastic urethane.

Abstract: An optical disc recording device comprises laser beam control means (12, 13, 14) of a mark length recording type which records data by forming pits on an optical disc (11) by radiation of laser beam for periods of time corresponding to pit lengths of respective pits. The laser beam control means shortens radiation time of laser beam as pit length of a pit to be formed increases. The laser beam control means also shortens radiation time of laser beam as immediately preceding blank length of a pit to be formed decreases. The shortening of the radiation time cancels tendency to increasing of pit length whereby a pit of pit length which is close to a set value can be formed. In one aspect of the invention, the laser beam control means advances starting of radiation of laser beam as immediately preceding blank length of a pit to be formed increases. The advancing of starting of radiation of laser beam enables adjusting of a pit starting end position to a predetermined position whereby blank length which is close to a set value can be obtained.

Abstract: The present invention constitutes a differential amplifier system (50) including a main differential amplifier (60) and a compensating differential amplifier (90) which are coupled together in a complementary manner to provide a composite output signal. 
     The amplifiers are of similar construction but have different circuit component values. Each of the amplifiers is of the differential type and includes emitter-coupled transistors (62) and (64) or (92) and (94), a feedback resistor (66) or (96) connected between the emitter leads (78) and (80) or (108) and (110) of these transistors and a pair of constant-current sources (68) and (70) or (98) and (100) separately connected to different ones of the emitter leads of the transistors. The circuit values of the constant-current sources and feedback resistors in the two amplifiers are different and are adjusted to allow the output of the compensating amplifier to cancel primary nonlinearities in the output of the main amplifier. The gain of the overall amplifier system is thereby maintained more nearly constant over a greater signal range and the composite output of the system is more linear over a wider range of input signals.

Abstract: A colour changeable photo-decorative pencil torch comprises a transparent hollow body (1) having an incident port of illuminating light at a part thereof and containing light scattering liquid (2) and a plurality of small pieces (3) floating therein being substantially as same as the light scattering liquid in specific gravity and having reflecting plates on the surface thereof. An illuminating light source (4) faces the incident port. A color plate 13 is housed in a chamber (8) and is placed at the connecting cross section of the transparent hollow body (1) and the illuminating light source (4). When the light is turned on, the illuminating light is color-changed by the color plate and is reflected by the small pieces (3) and scattered by the scattering liquid without being decreased in intensity . Since the small pieces have substantially the same specific gravity as the liquid they can freely move or float in accordance with the movement of the liquid and they reflect the color-changed light in all directions. Since the color   plate can move with respect to the light source, the lights for illuminating the respective small pieces can be momently color-changed. Thus, when swinging the color-changeable photo-decorative pencil torch while illuminated, the light observed through the transparent hollow body shines in various colours.

Abstract: A dual port read/write register file memory includes means for performing a read/modify write cycle of operation within a single system cycle of operation. The register file memory is constructed from one or more (RAM) addressable multibit storage arrays organized to form a dual read port, single write port RAM (10-1). Additionally, the register file includes a plurality of clocked input registers (10-3) arranged in pairs for storing command, address and data signals for two write ports. The different pairs of registers are connected as inputs to a first set of multiplexer circuits (10-5) whose outputs connect to the write control signal, address and data inputs of the single write port. The single write port of the register file memory is enabled for writing twice during each cycle. This allows data clocked into the input registers during the previous cycle to be written sequentially into the register file storage locations. By writing data into the input registers instead of the register file memory in a previous cycle, the time required for writing is reduced to a minimum.
