Abstract: ABSTRACT OF THE DISCLOSURE     An optical mass storage device for use in data processing systems.  Two or more lasers provide separate read and write laser beams having different wavelengths.  The read and write laser beams can be orthogonally polarized.  A polarizing beam splitter combines the read and write beams along a common optical path to an optical head.          The head directs the combined beam to a magneto-optic storage medium.  A read beam is reflected back by the medium to the common path through the head.  A dichroic beam splitter disposed in the common path between the head and the polarizing splitter reflects the read beam to an optical detector.  If more than one write laser is necessary, a second dichroic splitter can be used to combine the multiple write beams and the read beam.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus are described for characterizing a semiconductor using the surface photovoltage (SPV) effect.  A region of the surface of the semiconductor is illuminated with an intensity modulated beam of light, the wavelength of the light being shorter than that corresponding to the energy gap of the semiconductor.  The surface photovoltage (SPV) induced in the semiconductor is measured under bias voltage conditions.  The intensity of the light beam and the frequency of modulation are selected such that the surface photovoltage (SPV) is directly proportional to the intensity and reciprocally proportional to the frequency of modulation.  Using the surface photovoltage (SPV) and the bias voltage (Vg) measurements, the charge induced in the semiconductor space charge region (Qsc) and the charge induced in the semiconductor (Qind) are determined.          This information is used to determine various parameters of the semiconductor including surface state density and oxide/insulator charge.  The technique is designed especially for use in characterizing semiconductor wafers, coated or uncoated. but may, if desired, also be used in characterizing MIS or MOS type semiconductor devices.  The apparatus includes a reference electrode assembly which in one embodiment comprises a button made of insulating elastomeric material and attached to a rigid plate made of insulating material.          A film made of insulating material and having a conductive coating on one side which serves as a reference electrode is attached to the button.  When SPV measurements are being taken, the film is pressed against the specimen with pressure sufficient to hold the reference electrode in close compliance with the specimen, with pressure being applied to the plate from an external source and being transmitted from the rigid plate to the film through the elastomeric button.

Title: Hydrogen peroxide recovery from coloured aqueous solutions
Inventor: HOCKING MARTIN BLAKE
IPC: C01B15/013
Filed: 1989-04-20
Granted: 1995-08-01
Abstract: A method of recovering hydrogen peroxide from coloured aqueous solutions is disclosed.  The solution is brought in contact with a non-ionic size-exclusion chromatography resin made up of packed particles having narrow, low molecular weight pores.  The higher molecular weight coloured constituents are largely excluded from the pores causing these constituents to be more rapidly eluted with water along the exterior of the particles.  Hydrogen peroxide molecules are small enough to enter the pores several times in their passage through the resin which slows their progress sufficiently to cause elution of hydrogen peroxide after the coloured constituents have been eluted, effectively resolving the two components.

Title: System bus preempt for 80386 when running in an 80386/82385 microcomputer system with arbitration
Inventor: BLAND PATRICK M
IPC: G06F9/44
Filed: 1989-04-26
Granted: 1993-05-11
Abstract: ABSTRACT          A multi-bus microcomputer system includes a cache subsystem and an arbitration supervisor.  A CPU is provided with a PREEMPT signal source which generates a preempt signal in CPU cycles extending beyond a specified duration.  The preempt signal is effective at any device having access to the bus to initiate an orderly termination or the bus usage. When that device signals its termination of bus usage, the arbitration supervisor changes the state or an ARB/GRANT conductor, which had been in the grant phase, to the arbitration phase.  During the arbitration phase each of the devices (other than the CPU) cooperates in an arbitration mechanism for bus usage during the next grant phase.  On the other hand, the CPU, having asserted preempt, responds to a signal indicating initiation or the arbitration phase by immediately accessing the system bus.
