摘要： In a method of photolithography in which optical radiation is directed onto a layer of photoresist coated on a substrate, the tendency towards generation of spurious image features is much reduced by selecting the substrate and the optical radiation used in the exposure step so that the substrate is absorptive of said optical radiation. The use of, for example, a coloured glass substrate together with optical radiation of appropriate wavelength is found to be highly beneficial in maintaining accuracy of the resultant image.

摘要： A laser velocimeter for measuring the relative speed of a surface and a source of coherent light directed at the said surface comprising optical and electrical means for generating two electrical signals one of which corresponds to the content of the speckle pattern produced by illumination of the surface by the light circuit means for obtaining a difference signal from the two electrical signals and frequency measuring means for determining the centre frequency of the signal spectrum of the difference signal to generate an electrical signal indicative of the relative velocity of the surface and source. The device can measure length or distance moved by integrating the velocity signal. The optical and electrical means include a grating in the path to one of two detectors or a linear array of photodetectors alternate ones of which are summed, to provide the two electrical signals one of which corresponds to the speckle pattern.

摘要： A method of optical data storage which comprises encoding data into a code of order M, where M is an integer of (3) or greater, and writing the encoded data onto a receptive optical data storage medium using a laser system capable of generating (M-1) distinguishable pits in the surface of the receptive optical data storage medium. With such a method, the resultant data storage medium contains M different states, these being the lands together with the (M-1) pit states. The invention may be practiced using a plurality of lasers in order to generate the (M-1) pit states; alternatively, a single adjustable laser may be employed, e.g. one in which the intensity and/or wavelength and/or polarisation state of the laser beam may be modulated. A writing system for effecting optical recordings is also disclosed, this system including a semi-conductor laser under control of an electronic circuit arranged to ensure that the current flowing through the semi-conductor laser is always greater than the threshold current at which light is emitted.

摘要： A gas fired melting apparatus (20) for particulate material. The melting apparatus has four successively connected vertically disposed sidewall members (28, 30, 32, 34), a floor member (26) and a roof member (24). These members define a cubic melting chamber (22) for containing a freestanding generally conical pile of particulate material to be melted. The relative sizes, shapes and positions of the chamber radiating surfaces as well as their relative distances from the pile surfaces promote heat transfer to the pile. A high temperature gas fired burner (45) is mounted in each sidewall adjacent to the corner formed by the tail end of one sidewall and the head end of a successive sidewall member. The axis of each burner is parallel with its successive wall member so the combined effect of the burners is to produce a toroidal flow of combustion products in the melting chamber around its central vertical axis.

摘要： A data storage medium which is suitable for production or replication by moulding, casting, embossing or a similar process against a tool. The data storage medium has a surface or a surface region which is strongly absorbent of at least a predetermined band of wavelengths of electromagnetic radiation. The surface or surface region includes a layer of a heat sensitive or radiation-sensitive material which has a textured surface pattern the pitch of which is smaller than the shortest wavelength of the predetermined band of wavelengths, and the depth (peak-to-trough) of which is at least 100 nm. The surface pattern is free from undercutting, and can comprise an array of protuberances or one or more sets of grooves (which may be intersecting). The textured surface is of high opacity or absorbance at least at, and just below, the surface which in use is to be exposed to writing radiation. A filled plastics material, e.g. PVC filled with carbon black, may be used. Alternatively, a layer of a dye polymer may be used. A tool for use in producing such a data storage medium, and methods of using the tool, are also disclosed. The data storage medium may be prepared in blank form for use as the consumer desires, or it may be pre-recorded in part or in entirety.

摘要： Optical data storage members in which the "guard bands" present between data-carrying tracks of conventional data storage members are used to carry information recorded in a manner which avoids the danger of cross-talk between adjacent tracks. One preferred arrangement consists of an optical data storage member comprising an optically-recordable surface having a plurality of tracks in which information may be recorded in analogue or digital form, the tracks being of a first type in which the material constituting the track is sensitive to radiation of a first predetermined characteristic and a second type in which the material thereof is sensitive to radiation of a second predetermined characteristic, wherein tracks of the first type alternate across the surface of the optical data storage member with tracks of the second type. The tracks may be constituted by a surface region (1, 2, 3, 4, 5) carrying a plurality of closedly spaced grooves (11, 12, 13, 14, 15), the grooves of one track being orthogonally directed with respect to those of its adjacent tracks. The predetermined radiation characteristic can be the polarisation state of the incident radiation.
