Abstract: Electrically biasable transfer members for use in electrostatographic transfer processes for transferring toner images from one support surface to another and methods for their preparation are described. The electrically conductive biasable transfer members comprise a conductive substrate (1) capable of supporting a uniform bias potential thereon and at least one layer or coating (2) of an elastomeric resilient polyurethane formed by reacting (a) a polyisocyanate prepolymer comprising the reaction product of a saturated aliphatic polyiso-cyanate, a saturated cycloaliphatic polyisocyanate, or an aromatic polyisocyanate and a polyol free of aliphatic unsaturation, preferably a polyalkylene glycol in which the alkylene group contains 2 to 8 carbon atoms, and (b) a hardening mixture comprising a polyol of (a) or a diamine free of aliphatic unsaturation, or a mixture thereof and, as a conductivity control agent, from 0.001 to 5.0 weight percent, based on the total weight of (b), of a complex of ethylene glycol or an oligoethylene glycol selected from the group consisting of di-, tri- and tetraethylene glycol with an ionizable ferric halide salt selected from the group consisting of ferric fluoride, ferric chloride and ferric bromide. 
     The resistivity of the elastomeric resilient polyurethane coating (2) on the biasable member is controlled or adjusted to within a desired level of resistivity due to the inclusion of the conductivity control agent in the polyurethane elastomer. Additionally, the inclusion of the conductivity control agent in the polyurethane elastomer reduces the sensitivity of the resistivity of the polyurethane coating on the biasable member to changes in relative humidity. Further, since the conductivity control agent is copolymerized with the polyisocyanate prepolymers and the polyols and/or polyamines which comprise the hardening mixtures used to make the elastomeric polyurethane coatings of the biasable members of the invention, the conductivity control agent is bonded covalently to the polyurethane elastomer matrix or network, that is, to the backbone, crosslinking or branched portion of the polyurethane elastomer, where it forms a permanently fixed part of the polymer and will not migrate therefrom resulting in a continuous change in the resistivity of the polyurethane coating over time and possible adverse affects on materials that may come into contact with the migrating agent.

Abstract: A digital spark timing control for an ignition system of a spark ignited internal combustion engine (10) comprises engine crankshaft position sensing means (14,16) which develops, by way of example, three reference pulses and eighteen position pulses for each complete revolution of the crankshaft (12). The reference pulses (CRANK 2) are angularly spaced by 120° and the position pulses (CRANK 1) by 20°. A spark timing value is computed by computing means (74) and its program is interrupted at the occurrence of a reference or position pulse. The system, at the occurrence of each interrupt, determines whether or not the spark is to occur in the next twenty degree period. If the spark should occur in the next twenty degree period, the system utilizes the most recent twenty degree time period to determine how long it will take the engine crankshaft (12) to rotate from its current position to the desired spark position. This compensates for spark timing errors that might otherwise occur due to changes in engine speed.

Abstract: In order to improve the signal-to-noise ratio of a known sigma-delta analogue-to-digital converter A, the input to the loop filter means 3, 4 (which can be regarded as an error signal between the analogue input and, ignoring imperfections in the digital-to-analogue converter 8, the analogue equivalent of the digital output), is filtered, amplified and converted to a digital signal in a second sigma-delta converter B. This digital signal is combined with the digital output of the analogue-to-digital converter A to produce an output of the two stage converter with improved signal-to-noise ratio. Phase and amplitude errors introduced before the signals are recombined are corrected for by an equalisation network which is calibrated at regular intervals by means of a test generator 18. The same technique can be employed to produce a digital-to-analogue converter, and a digital modulator, with improved signal-to-noise ratio.

Abstract: In the potential sensor correcting apparatus of the present invention, two reference bias voltages are applied to a photoreceptor drum (1) by a low reference bias unit (21) and a high reference bias unit (22), and the values measured by a potential sensor (4) are stored in a memory (23a) of a control unit (23). Based on the measured values stored in the memory (23a), there is determined a first straight line (Y₁) which represents the relationship between the detected voltages and outputs of the potential sensor (4). Then, there is obtained a second straight line (Y₂) which has the same inclination as that of the first straight line (Y₁) and which passes through the origin. Based on the second straight line (Y₂) thus obtained, the output of the potential sensor (4) is corrected. Thus, the output of the potential sensor (4) can be accurately corrected without any influence exerted by residual charge.

Abstract: In an individual identification apparatus, a hologram (11) recorded on a card is irradiated with laser light to read out a finger print image of a specific person. A finger of an arbitrary person to be identified with the specific person is irradiated with laser light to obtain a finger print image. Thus obtained finger print images are jointly written in a first spatial light modulator (SLM2). Then, the joint image is read out and Fourier transformed by lens (5) to obtain a Joint Fourier Transform image, which is then written in a second spatial light modulator (SLM2'). The Joint Fourier Transform image is then read out and Fourier transformed by lens (6) to obtain a pair of output correlation peaks. A photodetector (7) detects the intensity of the output correlation peaks and outputs a signal indicative of the intensity. A threshold processor (61) compares the value of the signal with a pre-determined threshold value to positively or negatively identify the arbitrary person with the specific person.
