Title: X-ray application system
Inventor: FORSYTH JAMES MORTON
IPC: G03F7/20
Filed: 1985-10-31
Granted: 1989-09-07
Abstract: In a X-ray lithography system, X-rays (12) are generated by a laser beam (14), focussed upon a target (16) within an evacuated chamber (24) to create a soft X-ray emitting plasma which also emits debris particles (46).  A thin curtain (52) of X-ray transparent gas is provided between the target (16) and a mask (30) used in the lithographic process to displace the particles (46) away from the mask (30). The curtain of gas also maintains a pressure differential across an opening (60) in the evacuated chamber (24) through which the X-rays pass towards the mask. In addition, by placing the mask close to the gas curtain but sufficiently far to avoid interference, the gas curtain may be used to cool the mask.

Granted: 1989-09-21
Abstract: A melt of thermoplastics material is injected into a mould which is heated to a temperature above glass transition when an amorphous polymer is used or above the melting temperature when a semicrystalline polymer is used. The mould is heated by means of a heating medium, which is supplied into a jacket space (6, 8) surrounding the shape-defining mould space (7) and is cooled, following injection by replacing the heating medium with cooling medium. A mould for use in the invention has a shape-defining mould space (7), the forming space of which mould space is surrounded by walls (32, 33) made of metal foil behind which a temperature controlling jacket (6, 8) is a formed. Temperature control is effected by passing fluid into the jacket.

Abstract: A system for transmitting data signals between control devices connected to each other by a transmission loop operated directionally dependent has a number of such control devices connected to the loop, with each control device including a signal compiler which compiles data signals to be transmitted in the form of a data signal block which includes at least one receiver address identifying another control device which is intended to receive the transmitted signal block. The signal compiler is followed by a transmit buffer which includes an intermediate storage. A prepared data signal block is accepted in the intermediate storage. A buffer control is connected to the intermediate storage. A transmit authorization signal is transmitted via the loop from control device to control device. Upon receipt of the transmit authoriztion signal by the relevant control device, the buffer control therein enables a word-by-word read-out of the data signal block stored in the intermediate storage. Before forwarding the received transmit authorization signal, the buffer control attaches a sender address and an end block identifier as the last entry to the data signal block which is to be transmitted. This last entry is attached to the data signal block in response to a signal which indicates an empty status of the intermediate storage.

Abstract: A fiber optic coupler (20) is formed by heating juxtaposed optically flat surfaces (34,36) formed on two lengths of optical fiber (22,24) to the glass transition temperature. The fibers bond together while preserving the molecular composition of the fibers at bonded region. Depending upon the depth to which the fibers are lapped to form the optically flat surfaces, the coupler may be either an evanescent field coupler or a core intercept coupler. The fibers may be mounted on curved substrates and then lapped to form the optically flat surfaces. The optical throughput of a fiber may be monitored during assembly of a coupler to permit adjustment of the positions of the optically flat surfaces to produce a desired coupling efficiency. The fibers may then be bonded together by application of energy from a suitable coherent light source such as a CO₂ laser.

Abstract: The preparation of a concrete having an air bubble system consisting of finely divided air bubbles is often desirable for the purpose of protecting the concrete against damages, for instance caused by frost. The composition of the air bubble system in fresh, or green concrete is identical to the composition in the hardened concrete and the invention is directed to a method of determining the quality of the air bubble system in fresh concrete, expressed by means of the specific surface of the system. The method consists in that the air bubbles are expelled from a sample of the fresh concrete, for instance by agitation in glycerol by means of a magnetic agitator and that the expelled air bubbles while ascending in for instance water, which is superposed upon the glycerol layer, are registered as a function of time whereupon the quality of the air bubble system is expressed by means of the analysis result.
