Patent EP-0330386-A2 (EP)
Inventor: HOULIHAN FRANCIS MICHAEL
IPC: G03F7/038
Filed: 1989-02-17
Abstract: Sensitive deep ultraviolet resists are formed utilizing a material that undergoes decomposition to form an acid together with a polymer including a chain scission inducing monomer such as sulfonyl units and substituent that undergoes reaction to form an acidic moiety when subjected to the photogenerated species. An exemplary composition includes poly(t-butoxycarbonyloxystyrene-sulfone) and 2,6-dinitrobenzyl-p-­toluene sulfonate. The sulfonate decomposes to form sulfonic acid upon irradiation. This acid reacts with the polymer group to form an acid functionality while the sulfone moiety of the polymer induces scission. As a result, the irradiated portions of the resist material are soluble in ionic solvents while the unirradiated portions are not.

Abstract: An apparatus for gasifying solid carbonaceous material in a circulating fluidized bed reactor (1). Particles are separated from the product gas at least in two stages so that in the first stage (2), mainly coarser, so-called circulating particles are separated and returned to the reactor. In the second stage (5), fine carbonaceous and ash-containing particulates are separated from the gas and are made to agglomerate at a raised temperature. Coarser particles thus received are returned to the reactor through a return duct (3, 33) together with circulating particles. Agglomeration is effected in a chamber (30), where a fluidized bed (31) composed of coarse particles is maintained. Fine particulate material (38) and oxygen containing gas (39) are introduced into the free upper part of the chamber so as to form a flame (40). The point of the flame penetrates into the fluidized bed. The ash material contained in the fins particulate material melts, and is conducted to the bubbling fluidized bed (31).

Abstract: An ion thruster is operable in an interplanetary space with plasma generated by microwae in a propellant atmosphere. A vessel (2) defines first (40) and second (41) hollow spaces and ends at an opening (43). A microwave generating unit (44) generates the microwave in the first hollow space as a standing wave penetrating into the second hollow space. A propellant supplying unit (3) supplies the propellant into the second hollow space to make the propellant absorb the standing wave and produce main plasma comprising main ions and main electrons. An accelerating unit (17) accelerates only the main ions into an ion beam to inject the ion beam through the opening into the interplanetary space. Preferably, a neutralizing unit (19) defines a third space (52) which is in communication to the first space and into which the standing wave penetrates. The propellant comes into the third space to produce neuralizing ions and electrons. The ions are pulled by the ion beam to leave the neutralizing electrons, which neutralize the vessel.

Abstract: The fault detection and bandwidth monitoring arrangement provides a counter in association with each virtual circuit crosspoint. The counters may be provided with a common or individual threshold value which when exceeded causes alarm signals to be generated. The counter arrangement is arranged to record the averaged imbalance of receive and transmit data at each switch port involved in the virtual circuit connection, and additionally is arranged to measure the difference between the net data flows of the corresponding incoming and outgoing ports. Therefore, it is possible to distinguish between the go/return traffic imbalance and an information loss situation in the switch.

Abstract: A robot-held tool 22 for applying a sealing strip 7 to a flange 6 comprises rollers 32 and 34 which are contra-rotated by a motor within a housing 54 and which engage opposite sides of the sealing strip to press it onto the flange, downward pressure onto the sealing strip being maintained by a non-driven roller 40. Roller 40 is supported on supports 42 and 44 whose upper ends are slidable within chambers 46,46A and sprung-loaded downwards. The robot must exert sufficient pressure downwardly onto the inverted base of the sealing strip via roller 40 to push supports 42 and 44 upwardly into the chambers 46,46A such that a striker 49 actuates a pneumatic or electrical switch 48. When this happens, the motor in housing 54 is energised and rollers 32 and 34 drive the tool along the flange in the direction of arrow D, thus pushing the strip firmly onto the flange. Switch 48 stops the motor automatically if insufficient downward pressure is applied.

Abstract: An electromagnetic friction brake in which a friction pad (20) on an electromagnet (11) frictionally engages a rotating armature disc (12) when the electromagnet (11) is excited. The electromagnet (11) is attached to a fixed mounting member (30) by a pair of pins (33, 34) which project into holes (35, 36) in the electromagnet (11). The pins (33, 34) and holes (35, 36) are arranged such that one pin (34) sustains all of the angular thrust which is imposed on the electromagnet (11) by the armature (12) while the other pin (33) sustains no angular thrust and serves to retain the electromagnet (11) radially of the armature (12). Such an arrangement of the pins (33, 34) serves to reduce accelerated wear which otherwise occurs at the leading edge portion of the friction pad (20).

Abstract: A position servo system has a position loop and a velocity loop. The position loop controls the stop-lock condition and provides for movement control within a range about the stop-lock position. The velocity circuit is employed for movements outside of the range of the position servo circuit. When the velocity servo's loop is being used, a compare circuit compares the servo drive signal from the velocity circuit with a signal generated by the position servo loop which is tracking the velocity servo loop. When the compare means finds that the servo drive signals have equal amplitudes, then the velocity servo loop is disconnected from an actuator with the position servo loop then connected to the activation for completing the movement to a desired or target stop-lock position. The above-indicated servo system controls a topping or fine actuator (46) carried on a carriage (34) moved by a coarse actuator (36). The fine and coarse actuators move along the same axis and transverse to movement of any work element, such as a record storage disk (30). The coarse actuator is continuously slaved to the positioning of the topping or fine actuator (46). A relative position sensor (37) disposed intermediate the fine (46) and coarse actuators (36) supplies a position error signal for enabling the coarse actuator (36) to continuously follow the fine actuator (46). Feed forward signals are supplied from the fine actuator (46) to the coarse actuator (36). A preferred embodiment is shown using an optical disk environment.

Abstract: 5 n7 A bottom-feed, biomass material gasification system feeds fuel such as green and wet woodchips from below up through a central opening in a stationary, perforate fire table which supports the mound-like fuel bed which is formed. A plurality of ring-like air manifolds contiguously below the fire table, and surrounding the fuel supply tube are separately provided with air in a controlled manner according to the demand for the combustible gas produced, and a greater volume of air is supplied to the centralmost manifold, than to the outer manifold, or manifolds. The system includes, in addition to a primary heating chamber, a secondary heating chamber which receives the hot gases generated in the primary chamber and, via a centrifugal cyclonic action, combusts fly ash particles which may remain entrained in the gas, before passing the hot gases to the boiler burner for combustion. The atmosphere in the primary combustion chamber is partially starved, insofar as the supply of oxygen is concerned, and is maintained under a lower pressure than the gases which outlet from the primary chamber to the secondary chamber so that there is a continuous suction or draft pulling the hot gases generated in the primary chamber directly to the secondary chamber. An ash disposal system has paddles mounted on a rotary band bearing on the fire table for moving the ash which is generated from the perimeter of the fire table, when the ash build-up is sufficient to warrant it.
