Abstract: The invention provides for the treatment of fixer medium in photographic processing. One the one hand, the fixer medium is extracted from the fixer station to a first treatment tank in which it is subjected to light electrolysis for regeneration of the fixer medium so that it can be re-circulated to the fixer station. When the fixer medium has reached a predetermined saturation condition of silver content, it is discharged from the first treatment station to a second treatment station where it is subjected to electrolysis for the removal of the silver. On the other hand, the fixer medium is constantly circulated from the fixer station to an electrolytic cell in which silver is extracted under an automatic control device which ensures that the electrolysing current is increased or decreased dependent upon the silver content of the fixer medium to ensure that the silver content keeps to a sensibly constant predetermined value.

Abstract: A slow start motor control circuit for applications wherein extremely accurate speed control is required, such as, in a centrifugal blood separator application is disclosed. In a blood separator, the degree of separation of cellular components, such as red blood cells and platelets, from the blood plasma is a function of the rotational speed of the centrifuge and the spin time. The control circuit controls the spin time and the rotational speed of the drive motor by controlling the voltage applied to the motor. The control circuit allows the drive motor to start relatively slowly to avoid cell breakage which can contaminate the plasma. After the centrifuge attains its desired operational speed, the speed of the motor is regulated and is relatively uninfluenced by ambient temperature variations.

Abstract: A memory cell (1) is read by first charging a pair of bit lines (13,14) to given positive potentials and then raising the potential of a cell access line (12) to render access transistors (10,11) conductive. The cell supply voltage (+V) is sufficient to cause substantial hot-electron stress in the n-channel transistors (3,5,10,11) of the cell if it were applied directly across their source-drain paths while they were conductive. However a limit is imposed on the maximum positive potentials which are applied to the bit lines (13,14) from the exterior, and on the minimum ratio of the sizes of the cell n-channel amplifier transistors (3,5) to the sizes of the access transistors (10,11) taking into account the threshold voltages of the amplifier transistors, and as a result substantial hot-electron stress does not occur. Substantial hot-electron stress is also prevented during a write operation by arranging that this is effectively preceded by a read operation.

Abstract: The weighing apparatus according to the invention is for use on a support surface which is subject to vibration. The apparatus includes a base adapted to be positioned on the support surface and having opposing first and second sides. The base is adapted to transmit vibrations from the support surface. A tray holds the product to be weighed and has a center of gravity adjacent the first side of the base. A load cell supports the tray on the base at the first side of the base. Strain gauges connected to the load cell generate a signal indicative of the weight of the tray and any product held thereby. The signal includes oscillating noise corresponding to vibrations transmitted by the base through the load cell to the tray. An auxiliary beam and counterbalance weight stablize the tray by minimizing at least some of the vibrations transmitted to the tray and by converting at least some of the lower frequency vibrations transmitted to the tray into vibrations having a frequency which is higher than the frequency of the lower frequency vibrations. The tray transmits reverse-phase vibrations to the load cell which result in noise in the signal. The auxiliary beam and counterbalance converts at ! least some of the reverse-phase vibrations transmitted to the load cell into vibrations having a frequency which is ' higher than the frequency of the reverse-phase vibrations.

Abstract: Apparatus and method for automated and semi-­automated installation of blind rivets, comprising mechanical, pneumatic, and electronic subassemblies, with self-diagnostic capabilities. The system includes a rivet transfer arm (43) external to the installation tool, which receives pneumatically fed rivets in a "home" position and transfers the rivets to an "advanced" position of alignment with the tool's nosepiece. A mandrel collection system (60, 68) routes separated mandrels from the tool to a remote receptacle (68) through a channel (60) under vacuum. Various sensors (PS1..., VS1..., PX1...) detect rivet placements, mechanism positions, and air pressure conditions, and signals from such sen­sors together with user inputs are received by a central processing unit (CPU 150). The CPU diagno­ses the state of the installation system, produces command signals for a plurality of solenoid valves (SV1-SV7) to regulate the system pneumatics, and reports status and fault conditions to the operator. The operating software may include self-correction routines, as for example one which recognizes unsuc­cessful loading of a rivet into the nosepiece and reattempts loading with a new rivet.

Abstract: A method of manufacture of semiconductor devices suitable for increasing the integration density of semi conductor integrated circuits, especially GaAs semiconductor IC devices. 
     This invention uses no third wiring metal, contact hole or through hole for connection between the Schottky junction (1,1′) and ohmic electrodes (2,2′) formed on the GaAs semiconductor substrade (7) required in the conventional technology, but provides a method for direct connection between the two electrodes stated above by means of vapour deposition, ion implantation, sputtering, CVD, plasma CVD, dry etching and wet etching. 
     Since the application of this invention enables the two electrodes stated above to be directly connected with high yield, the element area at the connecting portion can be reduced to less than half as compared with the same required in the conventional method, the total element area can be substantially reduced.

In a further embodiment, a process is provided for treating a virgin arylene sulfide resin, wherein a virgin arylene sulfide resin is slurried in a buffer solution having a pH less than about 9.35 but greater than that necessary to result in at least a partial curing of the virgin arylene sulfide resin. The treating process of this invention is conducted at an elevated temperature, below the melting point of the virgin arylene sulfide resin, while in the substantial absence of a gaseous oxidizing atmosphere. The treated arylene sulfide resins are recovered from the polymer slurry in a manner which does not result in at least a partial curing of the treated resin.

Abstract: A method and apparatus for interpolating between data samples (V S ) that preserves the frequency spectrum of a sampled analog signal (V O ) is provided. Data samples (V S ) are interpolated to produce interpolated values (V IV ) that contain frequency domain information that accurately replicates an original frequency spectrum (24) of the analog signal (V O ) is disclosed. A signal processor (10) reads data samples (V S ) which occur at sampling times (t S ) and resample times (t R ) at which the V S  values are interpolated. A set of t S  times are found near each t R  time. A digital FIR filter having a frequency function (H(fT)) and a continuous impulse response function h (           t       T             ) is embodied in software form within a program that controls the signal processor (10) where T is the width of the filter impulse response. The signal processor (10) convolves an offset continuous impulse response function      with the V S  values. A plurality of convolved values (V C ) are summed at each t R  time to produce an interpolated value (V IV ) at each t R  time. The frequency response function (H(fT)) of the digital FIR filter reduces aliasing errors introduced by spectral images (25a and 25b) of the original frequency spectrum (24) and reduces amplitude errors caused by the filter's pass band ripple (38). The V IV  values contain frequency domain information that accurately replicates the original frequency spectrum (24).
