Patent EP-0209311-A2 (EP)
Inventor: KANEKO EIJII
IPC: H01S3/036
Filed: 1986-07-08
Abstract: A gas laser apparatus which has a positive electrode and a negative electrode disposed along a gas flow direction, and a pair of resonance reflectors disposed in a direction that perpendicularly intersects the gas flow direction. The negative electrodes include an appropriate number of unit electrodes connected to a power source. The unit electrodes include a plurality of needle electrodes aligned in the gas flow direction, the respective needle electrodes of which are covered with insulators leaving pointed ends thereof uncovered, and the pointed ends are interconnected by conductive thin wires. The insulators prevent the glow discharge area of the respective needle electrodes from being increased. In addition, the conductive thin wires serve to cause adjacent needle electrodes to commence glow discharge, whereby stabilization of glow discharge can be achieved. The gas flow velocity may be decreased at the centre of the gas flow path to render the flow velocity more uniform across the gas flow path. For example. a rod structure may extend across the centre of the flow path or the needle electrodes at the centre of the flow path may be thicker than electrodes away from the flow path.

Abstract: Twin linkage assemblies shift a support platfom between a low profile, fully collapsed position and a fully extended position of a height suitable for supporting a workman underneath an aircraft or for supporting, for instance, an engine at a comfortable working position. A hydraulic cylinder and piston assembly (76) is connected at opposite ends to swivel members (86,88,94,96) and torque arms (102,104,110,112), the latter of which are connected to short links (64,70) which in turn are coupled to linkages (48,56) interconnecting a base (22) and the work supporting platform (24). The torque arms (102,104,110,112), in cooperation with the swivel members (86,88,94,96), facilitate swinging of the links (64,67) and linkages (48,56) to reduce the force necessary to separate the platform (24) and base (22) to a value smaller than would otherwise be required. In preferred embodiments, opposite end regions of the cylinder (78) and piston (80) are provided with trunnions (82,84) that carry the swivel members (86,88,94,96) and which engage stops (46,34) mounted to the platform  (24) and base (22), to resist rotational urging of the piston and cylinder assembly (76) and to assist the torque arms (102,104,110,112) in swinging the links (64,70) and associated linkages (48,56) both when the assembly is collapsed and when the assembly is extended.

Abstract: An accurate high speed gripper assembly (12) for use in handling articles in an automated manu­facturing process. The gripper assembly (12) includes a pair of movable fingers (14, 15) which depend from movable carriages (18, 19) mounted in a housing (13) rotatably mounted on the end of a robot arm (11). A pair of stepper motors (31, 33) are mounted in the housing (13) and are connected to rotary actuators (26, 27) which displace the fingers (14, 15) in discrete incremental steps toward or away from one another when rotated. Compliant elements (51) provided on each finger cooperate with force/torque sensors (52, 53) for determining the proximity of the fingers to an article to be gripped and the gripping force applied by the fingers (14, 15). The sensors (52, 53) generate signals which are processed in a controller (35) that regulates operation of the stepper motors (31, 33) so as to achieve desired finger move­ments and gripper forces.

Abstract: A fluorometer probe head and a method of operating a probe to overcome problems of reflectance, for example, for determination of chlorophyll in plant leaves, uses a red LED (6), whose radiation does not cause fluorescence in the sample, and a green LED (7), whose radiation causes fluorescence in the sample, consecutively directed to a particular target spot (5). A photodiode (8) records fluoresced and reflected signals and an accurate result is obtained by subtracting the reflectance obtained with the red LED (6) from the gross reflectance and fluorescence value obtained with the green LED (7), to give the fluorescence at the test point.

Abstract: An apparatus for contacting solids with gases, preferably a needle coke preheater, which includes an elongated housing (12) having an entrance and an exit and means for introducing solids into the entrance of the housing. A bed support (16) divides the housing into an upper chamber (30) and a lower chamber (28) and is declined from the horizontal at an angle such that the solids introduced into the entrance of the housing slide down the bed support toward the exit of the housing. The bed support contains a plurality of openings distributed between two solid rectangular borders which serve as the two long parallel sides of the bed support. The openings are sufficienlty large so that gases can flow from the lower chamber in contact with the solids and then into the upper chamber. The solid rectangular borders prevent preferential flow of the gases up the walls of the housing by forcing the gases to flow toward the center of the bed support. The apparatus also contains means for introducing gases into the lower chamber of the housing, means for removing gases from the upper chamber of the housing and means for removing solids from the exit of the housing.

Abstract: Technological process for the production of a GaAs self aligning double recess to be applied to power MESFET devices. 
     The process consists of a first exposure of the planarizing layer to define the length of the first recess, into which the gate is set and is followed by a second exposure of the same photopolymer to define the length of the second recess. 
     The resulting double recess structure, through suitable dimensioning, related to the active channel doping, gives way to high power MESFET devices; in particular it makes possible the application of high source to drain voltages (V DS  typically 60 - 80 V) to the device before breakdown processes are triggered.

Abstract: Improved processes for the removal from solution of multi-valent alkaline earth metal and/or heavy metal cations are taught, having excellent combinations of cation capacity and resistance to bead breakage. The processes use specified polymer resin beads functionalized with chelating functionalities such as alkylaminophosphonic moieities or iminodiacetic acid moieites. The beads are prepared by the specified process to have a decreased amount of cross-linking in the shell area as compared to the core. An additional aspect of the invention is an improved gel-type chelating resin having core-shell morphology and alkylaminophosphonic functional groups which is found to exhibit surprising combinations of dynamic capacity, osmotic shock resistance, and physical strength. This chelating resin has been found to be very suitable for the removal of calcium from brine solutions prior to the use of such solutions in membrane electrolysis cells for chlorine production.

Abstract: Downstream of a paper leaf stacking machine, e.g. a paper napkin folder, there is a device comprising supports (2) on each of which is mounted at least one leaf separating finger (1). 
     Each support is kept, by a stop (3), in a fixed position corresponding to that in which the paper folder forms and deposites the folded leaves (4). After a predetermined number of leaves have been deposited, the stop is disengaged and the finger is snapped in between one sheet and the next and so advances at least part of the way with the stack of folded sheets. At a certain point of the path, each pack of leaves, as marked by two successive fingers, is lifted out by a forceps or the like and each support is returned to its starting position.

Abstract: In a frequency response analyser for operation at high frequencies a signal of frequency F for application to a system under test (10) is generated from a frequency synthesiser (12) capable of operation only at a relatively lower frequency F/K by generating a first signal (19) of frequency at the relatively lower frequency F/K by generating a second signal 104 at the relatively higher frequency (f+F) and generating a third signal (at 114) of F(1-1/K). 
The second signal is applied to the system under test and an output signal (at 16) derived therefrom. 
The output is multiplied by the third signal to provide a product signal, and the product signal is analysed with respect to first signal by means of a corelator (14). 
     The present invention overcomes the limitation in maximum testing frequency imposed by the frequency synthesisers of prior art frequency response analysers.
