Abstract: An optical disc drive unit, for supporting and rotating an optical disc, includes an optical head, movable across a main face of such an optical disc when the unit is in use, for providing an optical beam to be incident at a desired point on the main face of the disc. The unit also comprises an actuator device, having a beam-deflecting member that is displaceable relative to the optical head to adjust the position of the point of incidence of the optical beam on the main face of the disc. The device also has drive means (62), for controlling such displacement of the said beam-deflecting member in dependence upon a drive signal applied to the drive means, and resilient biassing means (24), connected between the beam-deflecting member and a body portion of the actuator device, for urging the beam-deflecting member towards an equilibrium position when no such drive signal is applied. 
     The unit is provided with offset compensation means (28, 30) operable when no such drive signal is applied to the drive means (62) to determine a bias signal which, applied to the drive means, serves to cancel any offset of the beam-deflecting member from a desired neutral position relative to the optical head, and operable thereafter to superimpose that bias signal on such drive signals applied to the drive means (62). 
     In such an optical disc drive unit adverse effects upon the operating characteristics of the actuator device arising from any unbalanced biassing forces provided by the resilient biassing means (24) can be substantially eliminated, whereby the speed and accuracy of tracking control in the unit can be improved.

Abstract: The present invention is directed towards the production of a single crystal semiconductor device mounted in intimate contact with a polycrystalline CVD diamond substrate which allows the high heat conductivity of diamond to keep the device cool. This device is made by a method comprising the steps of placing in a reaction chamber, a single crystal of silicon heated to an elevated CVD diamond-forming temperature. A hydrocarbon/hydrogen gaseous mixture is provided within the chamber and is at least partially decomposed to form a polycrystalline CVD diamond layer on said silicon. During this deposition/growth phase, an intermediate layer of single crystal SiC has been found to form between the single crystal of silicon and the polycrystalline CVD diamond layer. In the next step of the process, the silicon is etched or removed to reveal the single crystal SiC supported by the polycrystalline CVD diamond layer. Finally, a semiconductor layer (e.g. silicon, SiC, GaAs, or the like) is grown on the exposed single crystal of SiC to produce a single crystal semiconductor polycrystalline CVD diamond mounted device.

Abstract: A two-stage Joule-Thomson cryostat (10) has a first-stage cryostat (12) with a helical-coil heat exchanger (14) and an isenthalpic gas expansion orifice (20) that discharges a mixture of cooled gas and cryogenic liquid into a liquid cryogen plenum (26). A second-stage cryostat (30) with a helical coil heat exchanger (32), wound to a larger diameter than the first-stage heat exchanger coil (14), is wound around and in thermal contact with the liquid cryogen plenum (26). This arrangement achieves a high degree of interstage heat transfer and cooling of the gas flowing in the second-stage heat exchanger coil (32) by the liquid cryogen in the first-stage liquid cryogen plenum (26). In operation, a gas flow management system (60), designed for rapid cooldown, initially passes a first gas of high specific refrigerating capacity through both stages (12 and 30). When the stages and structure are sufficiently cooled to the near-vicinity of the normal boiling temperature of the first gas, the flow of the first gas through the second-stage cryostat (30) is discontinued, and a flow of a second gas of lower normal boiling temperature than the first gas is passed through the second-stage cryostat (30). The flow of the first gas continues through the first-stage cryostat (30).

Abstract: A method for coating finely divided material with titania is disclosed. The method involves the fluidization of the finely divided material (16) in an inert carrier gas containing vaporized titanium isopropoxide. The isothermal fluidized bed (15) is kept at a temperature equal to or below approximately 300°C. The vaporised titanium isopropoxide reacts to form a coating of titania on the surfaces of the particles (16) within the fluidized bed (15). The greatest coating efficiency occurs when the fluidized bed is kept at approximately 300°C for approximately the first 10 minutes of the reaction and thereafter at approximated 250°C. The titania coating process is particularly useful for electroluminescent phosphors such as copper doped zinc sulfide phosphor. The titania coated electroluminescent phosphors are relatively insensitive to moisture. Lamps made from the coated electroluminescent phosphor are also relatively insensitive to moisture.

Abstract: Multiprocessor systems frequently consist of a network of node processors which are connected to one another in a particular topology, and at least one host processor which controls the network. To execute a task, the host processor loads the node processors with a program which is followed by data either from the host processor or from a peripheral device, which may also be connected to the network, which data are processed in accordance with the loaded program. To avoid the network having to be newly loaded in each case when several similar tasks are executed in succession as occurs, for example, in the processing of successive images, the network program is designed in such a manner that all node processors run through a cycle of three parts, a command for starting a task being received from the host processor in the first part, the execution occurring with exchange of data packets between node processors in the second part and a finished message being collected from all node processors in the third part, after which all node processors await a new command from the host processor in order to execute an identical or similar task with new data. In addition, various methods of information transfer in the network of the node processors are described. …<IMAGE>…
