Patent EP-0303191-A2 (EP)
Inventor: ARAI TOHRU
IPC: C23C16/34
Filed: 1988-08-04
Abstract: Particles of a layer-forming agent containing at least one element for forming a surface layer of e.g. a carbide on the material to be treated are disposed in a furnace below and/or at the side of the material to be treated. A fluidizing gas is introduced into the furnace below the layer-forming agent for fluidizing a powder of alumina or other refractory material to form a fluidized bed above the layer-forming agent, while the agent is not fluidized. The furnace is heated and a solid halide is supplied into the furnace below the layer-forming agent. The halide is sublimable to produce a gas which activates the element, so that it may combine with a particular element which the material to be treated contains, whereby the surface layer is formed thereon. An apparatus for forming such a surface layer is also provided.

Abstract: Known screen printing machines in which the screen frame is subjected to a lifting movement behind the traversing squeegee cannot be used for a screen printing activity in which the squeegee runs in the reverse direction without disadvantages arising. 
<??>It is therefore proposed to arrange the swivel axis for the screen frame through the central plane of the screen frame running vertically to the squeegee movement and in each case to provide devices which are able to lift the screen frame on both sides of the swivel axis. This configuration permits use of the screen printing machine for movements of the squeegee in both directions while retaining the advantages of a compensation for print faults. 
<??>The new screen printing machine is particularly suitable for the printing of circuit boards.

Abstract: A thin-film coating method for laminating thin-films to opposing surfaces of a substrate and an apparatus for accomplishing the same. A pair of tack members 10E are respectively disposed on opposite sides of the substrate and are moveable in a direction perpendicular to the direction of conveyance of the substrate so as to temporarily tack forward end portions of the thin-films to the substrate. Compression rollers 16 are movably disposed with respect to the substrate such that the compression rollers can respectively contact forward end portions of the thin-films after the tack members have been removed from the substrate. The compression rollers are rotatable to thereby convey the substrate and to cause the thin films to adhere to the opposing surfaces of the substrate. A void-space preventing agent device 30 is provided in a position upstream to the tacking position. The device 30 deposits a void-space preventing agent in the form of mist on the substrate so as to prevent void spaces from developing on the contacting surfaces between the substrate and each of the films.

Abstract: A method and an apparatus are provided for burning gaseous fuel when the composition of the fuel varies at times. Main injection ports and sub-injection ports are arranged so that the fuel injected through the sub-injection ports is ignited by the flame formed from the fuel injected through the main injection ports. Fuel passages (22,23) are provided for conducting the gaseous fuel separately to the two groups of injection ports. A control valve (24) adjusts the ratio of the fuel flow to the main injection ports to the fuel flow to the sub-injection ports. In operation the proportion of the fuel to be injected through the main injection ports is increased as the rate of burning of the gaseous fuel increases.

Abstract: A process and apparatus for improved expansion of tobacco is disclosed wherein tobacco impregnated with a volatile impregnant in an impregnator (6) is treated prior to expansion, in an intermediate zone (12) wherein a gaseous phase containing volatile impregnant vapors is removed and later recovered. The thus treated tobacco is thereafter expanded in a conventional expansion zone (18) by contacting the tobacco with a stream of hot gases. The arrangement results in more efficient use of volatile impregnant and can provide less residual impregnant in expanded tobacco while not decreasing the degree of tobacco expansion.

Abstract: A wireless data coupling system for transmitting data such as torque from a rotating shaft to a stationary receiver includes several photocells spaced continuously around the circumference of the shaft along with a plurality of stationary light pipes with corresponding light sources for simultaneously illuminating all of the photocells. This provides a means of powering the rotating components. From a data standpoint an analog signal from a strain gauge is converted to a digital signal which is transmitted bit by bit by a pair of light emitting diodes one of which acts as a data sync. The stationary receiver contains columns of phototransistors to receive both the data and data sync pulses. Initiation of the transmission of data is started by a start pulse which occurs first in time and thereafter send pulses from the stationary system actuate the data and data sync pulses from the rotating system.

Abstract: A polyimide pattern is formed on a substrate by providing a layer of photosensitive polyimide precursor containing the polyimide precursor and a compound having a photosensitive group on the substrate and prebaking the layer. The layer is then exposed imagewise to actinic radiation through a photomask to form an exposed image pattern of the polyimide precursor in the layer. The unexposed areas of the layer are removed using a liquid developer and the exposed image pattern is cured by heating. In one aspect of the present invention, the prebaking step employs a judicious selection of times and temperatures to eliminate the problem of formation of a white residue that occurs from using prior art prebake procedures. In another aspect of the present invention, a particular liquid developer composition is employed to facilitate the formation of sloped vias in the polyimide. In another aspect of the present invention, a particular range of exposure wavelength(s) is employed to obtain smooth walled vias.

Abstract: A phoneme estimator in a speech-recognition system includes energy detect circuitry for detecting the segments of a speech signal that should be analyzed for phoneme content. Speech-element processors then process the speech signal segments, calculating nonlinear representations of the segments. The nonlinear representation data is applied to speech-element modeling circuitry which reduces the data through phoneme specific modeling. The reduced data are then subjected to further nonlinear processing. The results of the further nonlinear processing are again applied to speech-­element modeling circuitry, producing phoneme estimates. The phoneme estimates are rearranged and consolidated, that is, the phoneme estimates are uniformly labeled and duplicate phoneme estimates are consolidated, forming estimates of words or phrases containing minimal numbers of phonemes. The estimates may then be compared with stored words or phrases to determine what was spoken.

Abstract: For an air spa, a non-return valve comprises a closure element comprising a head (22) and a stem (20) which depends from the head through an outlet opening (24) from a chamber (12) of an air supply passage. A stud (18) projects upwards from a resilient diaphragm (16) closing a bottom end of the chamber to become magnetically coupled to the stem (20) of the closure element when the valve is closed. In the closed condition of the valve the diaphragm is displaced upwards to load the head (22) downwards on to a seating around the outlet (24). The effective area of the diaphragm (16) is greater than that of the head (22) and upon operation of a blower air is supplied under pressure to the chamber (12), through an inlet (14), to displace the diaphragm (16) and break the magnetic coupling with the closure element (20, 22). The head (22) can then be lifted by the air pressure to open the valve.
