Title: A method for manufacturing a thin film
Inventor: KIM YEONG-KWAN
IPC: C23C16/455
Filed: 1998-12-04
Granted: 2003-03-12
Abstract: A thin film manufacturing method is provided. The method includes the step of chemically adsorbing a first reactant on a substrate by injecting the first reactant into a chamber in which the substrate is loaded. Physisorbed first reactant on the chemically adsorbed first reactant is removed by purging or pumping the chamber. After the first reactant is densely chemically adsorbed on the substrate by re-injecting the first reactant into the chamber, the physisorbed first reactant on the dense chemisorbed first reactant is removed by purging or pumping the chamber. A second reactant is chemically adsorbed onto the surface of the substrate by injecting the second reactant into the chamber. Physisorbed second reactant on the chemisorbed first reactant and the second reactant is removed by purging or pumping the chamber. A solid thin film is formed by chemical exchange through densely adsorbing the second reactant onto the substrate by re-injecting the second reactant into the chamber. According to the present invention, it is possible to obtain a precise stoichiometric thin film having a high film density, since the first reactant and the second reactant are densely adsorbed and the impurities are substantially removed by pumping or purging

Title: Network echo canceller and method for cancelling network echo
Inventor: SIH GILBERT C
IPC: G10L19/012
Filed: 1993-09-24
Abstract: An echo canceller and method for cancelling in a return channel signal an echoed receive channel signal where the echoed receive channel signal is combined by an echo channel with an input return channel signal. The echo canceller has a first filter which generates first filter coefficients, generates a first echo estimate signal with the first filter coefficients, and updates the first filter coefficients in response to a first filter control signal. A first summer subtracts the first echo estimate signal from a combined return channel and echo receive channel signal to generate a first echo residual signal. A second filter generates second filter coefficients, generates a second echo estimate signal with the second filter coefficients, and updates the second filter coefficients in response to a second filter control signal. A second summer subtracts the second echo estimate signal from the combined signal to generate a second echo residual signal, and provides upon the return channel the second echo residual signal. A control unit determines from the receive channel signal, the combined signal, and the first and second echo residual signals, one of a plurality of control states wherein a first control state is indicative of a receive channel signal above a first predetermined energy level, wherein when the control unit is in the first control state it generates the first control signal and generates the second control signal when at least one of a first energy ratio of the first echo residual signal and the combined signal and a second energy ratio of the second echo residual signal and the combined signal exceed a predetermined level. <IMAGE>

Title: Recovery of indigo suspended in rinse water from vat dyed yarns
Inventor: HANET JACQUES
IPC: D06P/
Filed: 1984-04-13
Granted: 1989-08-30
Abstract: The arrangement is intended for recovering indigo dyestuff contained in suspension in the rinsing water used on vat-dyed yarns. It comprises a circuit through which the water is circulated and possibly recirculated, and containing a number of ultra-filtration batteries. The pressure and the flow rate in the circuit are controlled (feed pump with valve and circulation pump with valve, respectively). The water is fed from a buffer vessel which receives the water from the rinsing vat and can be connected into the circuit to limit the concn. increase of suspended dyestuff in the filtration batteries. Recovering indigo dyestuff suspended in rinsing water used on vat-dyed yarns, the arrangement permits recovery of more than 15% expensive dyestuff which is normally lost in the effluent and eliminates the effluent pollution otherwise incurred. The resulting reduction of COD and BOD (chemical and bio-chemical oxygen demand) is low. The recovered dyestuff is re-usable and produces equal depth of colouring on the yarn with equal friction -fastness under repeated washing as compared with fresh dyestuff. The bath prepared with recovered dyestuff is slightly cloudy compared with the clear bath from fresh material, but this presents no problem.

Title: Friction driven press with crank - has overrun of ram after work stroke prevented by mechanical stop
IPC: B30B/
Filed: 1977-03-07
Granted: 1986-02-03
Abstract: If a press runs through after a work stroke and the electrical stop arrangement fails, a second work stroke would occur. This can be prevented by means of a mechanical stop (15) mounted e.g. on a gear wheel (14) which is attached to the driving crankshaft. A hydraulic cylinder (5) is mounted on the frame of the press. AT the end of the piston which is mounted in this cylinder, a small hydraulic cylinder (11) is mounted which can push a plunger into the path of the stop pin on the gear wheel. The space in the end of the main cylinder between the end face of the piston and the rear wall of the cylinder is filled with hydraulic fluid and is connected by a number of choke holes (3) to a chamber (E). When the piston is pushed in by the stop, the hydraulic fluid flows out of the choke holes. The choke holes are progressively blocked by the piston.

Title: Polyimides prodn by single-stage catalystic condensn - from diamines and tetra carboxylic acid dianhydrides
Inventor: VASILY VLADIMIROVICH KORSHAK
IPC: C08G/
Filed: 1974-12-10
Granted: 1978-10-20
Abstract: Prepn. of polyimides by a single stage high temp. poly-condensn. at 100-200 degrees C of diamines and tetracarboxylic acid dianhydrides in an inert, immiscible with H2O, polar organic solvent, and in presence of a carboxylic acid catalyst, used in the ratio 0.25-10 pref. 0.8-2.5 - COOH gps. per polyimide member. As carboxylic acid catalyst an acid of the general formula: R(COOH)n is used, esp. acetic or benzoic or a tetracarboxylic acid; R is an aliphatic, aromatic or heterocyclic radical and n = 1-4. Polycondensation of diamines with 3, 31, 4, 41-benzophenonetetra-carboxylic acid dianhydride (I) occurs at 120 degrees - 140 degrees C; with 1,4,5,8-naphthalene tetracarboxylic acid dianhydride (II) reaction is carried out at 190-220 degrees C. As organic solvents, nitroaromatic hydrocarbons, aliphatic and aromatic chlor-hydrocarbons, or aromatic nitriles are useD. The advantage of the catalytic method used is an increase in reaction velocity thus allowing high mol. wt. polyimides to be prepd. at a lower temp. i.e., 100 degrees C, or to shorten reaction time to egg., 1 hr. Only the catalytic procedure allows linear, fusible, soluble and hardenable polyamides on the basis of (I) to be prepd., which are converted to an infusible, insoluble condition at 200-300 degrees C. A single stage process without catalyst results in a three dimensional insoluble prodt. High mol. wt. film forming polyimides using less reactive dianhydrides with 6 membered rings e.g., (II) can be prepd. (having a viscosity index = 1-2 dl./g.). Such polyimides e.g., polypyromellitic imides have significant heat and hydrolytic resistance. Polyimides prepd. by the catalytic process have mean mol. wT. = 50.103-200.103; viscosity index = 0.7-2.0 dl./g.; glass transition temp. 320 degrees - 520 degrees C; decompsn. begins at 450 degrees - 500 degrees C. They possess film and fibre forming props.

Title: Absorption heat exchange unit - in which temp. and concn. gradient is established between top and bottom
IPC: F25B/
Filed: 1978-07-21
Granted: 1987-03-11
Abstract: Absorption heat exchange is effected by generating a refrigerant vapour from an absorbent soln. rich in refrigerant, condensing the refrigerant vapour, evaporating the condensed refrigerant vapour and absorbing the evaporated refrigerant vapour into an absorbent soln. weak in refrigerant to form the absorbent soln. rich in refrigerant. A falling film of absorbent soln. forms on heat exchange surfaces from the top to the bottom of the vessel and refrigerant vapour is released at an inlet at the bottom into a zone adjacent the falling film. The refrigerant vapour is absorbed into the absorbent soln. and heat withdrawn from the falling film through the heat exchange surfaces to establish a temp. and concn. gradient between the top and the bottom of the vessel. Used in an absorption heat pump for mixing soln. depleted of refrigerant e.g. weak liquor from the generator, with evaporated refrigerant from the condenser. Because of the temp. and concn. gradient refrigerant introduced at the inlet contacts the least hot and richest soln. in the absorption zone. Consequently the evapn. of absorbent into the dry vapour and the accompanying temp. drop is minimized at that point. In addn. the temp. at the hot top end adjacent the weak liquor inlet is maximised so that the temps. in the rich liquor and coolant are maximised.
