Patent EP-0174877-A2 (EP)
Inventor: FORSYTH JAMES MORTON
IPC: H01L21/027
Filed: 1985-10-31
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.

Abstract: A method of forming an electrical short circuit between adjoining regions of an insulated gate semiconductor device uses retained portions of insulating layers formed over gate electrodes as an etching mask. The insulating layers are formed over the exposed surfaces of the insulated gate device, including the gate electrodes, and are then selectively removed to leave the retained portions covering the gate electrode top surfaces and sidewalls while exposing selected areas of a semiconductor substrate. The retained portions of the insulating layers are then used as an etching mask to etch away selected portions of the adjoining regions in the semiconductor substrate and expose a junction therebetween. The electrical short circuit is subsequently formed at the exposed junction.

Abstract: An electromagnetic contactor according to the present invention is so constructed that the electromagnetic device and the fixed point of contact are fixedly fitted into a casing which is divisible in the direction along the moving direction of a polar contact. Moreover, a bottom casing with a screw mounting hole is fitted in the outer peripheral portion at the lower end of the casing. Therefore, the rigidity of the casing as a whole is enhanced, and at the same time the working characteristics can be prevented from being changed when the screw is mounted. Furthermore, the positioning accuracy of the electromagnetic device relative to the fixed point of contact is determined only by the dimensional accuracy of the casing and the electromagnetic device, and by the position accuracy of the fixed point of contact. The contact pressure is improved to be stable.

Abstract: In a process for the biological sewage purification of sewage containing organic as well as nitrogen-containing pollutants, carbon decomposition and nitrogen removal are performed. The sewage is gassed with air and/or pure oxygen in a reactor in the presence of a biomass fixed on a support material and then, in a secondary sedimentation step, is separated into purified water and sludge. The sludge is at least partially recycled into the reactor. Particles of support material in lumpy and/or granulated form and in free-flowing quantities are employed in the reactor as support material for the microorganisms. To attain both a high carbon and a high nitrogen decomposition at the same time, the reaction is provided with BOD5 volume load of 0.4 to 2.5 kg/m3d and a TKN volume load of 0.1 to 0.8 kg/m3. d, BOD5 decomposition, nitrification and denitrification are all performed within an undivided reactor, in which the O2 concentration within the liquid is 0.5 to 4 mg/l and the support material occupies 15 to 35% of the reactor volume.

Filed: 1987-02-03
Abstract: A plurality of data transmitting and receiving devices(1) are inter-connected by an interface bus system configured as two or more sub-bus systems(2,3,4) connected into a chain by a corresponding number of communication links(5). Each sub-­bus system(2,3,4) includes a communications arrangement(7) interfacing the sub-bus system with the associated link or links(5). The overall interface bus system operates in accordance with a data transfer protocol that involves a handshake procedure requiring the participation of all active devices(1) connected to the bus system. In order to avoid the whole installation locking up upon one sub-­system(3,4) becoming non-responsive, each communication arrangement(7), other than the one associated with the last sub-bus system(4) in the chain, is arranged to check the responsiveness of its down-chain neighbour when requested to do so by a control input from the installation controller(1A). In the event of the down-chain system being unresponsive, the communications arrangement(7) functionally truncates the chain at its sub-bus system.

Abstract: An AM-RF transmitter includes a transmitter stage having a DC power supply terminal energizing by an AC to DC converter including reactances having a resonant frequency approaching frequencies of an information, modulating signal. The voltage applied by the supply to the DC power supply terminal is reduced to such an extent as to induce distortion in the transmitted AM-RF carrier in response to the transmitter stage being modulated by positive amplitude variations having frequencies that approach the resonant frequency. The amplitude of the transmitter stage modulation is increased when the distortion would otherwise occur to substantially prevent the distortion. The information signal is modified in amplitude by only AC coupling a replica of the DC power supply voltage variations to one input of a four quadrat multiplier, having a second input responsive to the information signal.

The joint centers of adjacent main chains are connected by means of supplemental links of larger cross section. The supplemental links are larger in cross section than the main links, so they form supplemental chains which are heavier than the main chains. The supplemental chains extend obliquely relative to the main chains, and their ends are fastened to the perimeter structure.
