Patent EP-0342940-A2 (EP)
Inventor: LAKIOS EMMANUEL N
IPC: C23F4/00
Filed: 1989-05-17
Abstract: A loading station receives a substrate into a load-lock volume pressure isolated from a loading station chamber which is open to a processing chamber. The volume is evacuated and the substrate lowered into the loading chamber. A transport arm moves the substrate frOm the loading station to a substrate carrier of a cooling fixture within the processing chamber. The carrier is connected to a clamp which together move vertically downward to lower the wafer onto a substrate seat of the fixture. During substrate processing the fixture is tiltable and rotatable and provides substrate cooling by solid-to-solid conduction, forced convection and free convection. 
     Solid-to-solid conduction is provided by the clamp. The substrate is pressed to the fixture by the cooling clamp having a circulating cooling fluid. 
     Forced convection is provided by a gas flowing into the microspic areas between the substrate and the fixture at a pressure high enough to cause bowing or lifting of the substrate and thus to create a gas region between the substrate and the fixture. An O-ring provides a seal under the pressure of the clamps near the periphery of the substrate to substantially seal the gas from entering the processing chamber. The gas flows into and through the gas region absorbing heat energy from the back surface of the substrate and flowing out of the region. 
     Free convection is provided by heat transfer between the substrate and the substrate seat. The pressure in the gas region is high enough that the mean free path of the gas   molecules is less than the distance between the substrate and the fixture. As a result gas molecules absorb energy from the substrate and intermix and transfer energy with other molecules. Some molecules collide with the substrate seat and transfer heat energy to the seat. After substrate treatment the gas is evacuated from behind the substrate prior to release of the clamps.

Abstract: There is described a method and apparatus for driving an electrophoretic display during a writing mode. During this mode the cathodes that are not being written into are pulsed in regard to the pulsing of a grid that is being written into. The grid that is being written into is associated with a cathode line which line is caused to assume a writing mode for a longer duration than the pulse applied to the writing grid. At the same time cathode lines which are not being written into are pulsed for a time duration equivalent to the time duration of the writing grid pulse. By pulsing the electrodes in the manner described above, one increases the writing speed of the electrophoretic display while maintaining a bright uniform background for the display.

Abstract: A method and system are disclosed for determining the density of a liquid, such as aircraft fuel (18), by measuring the amplitude of the reflections of ultrasonic pulses from the faces of the walls (21 and 21′) of a reference material (20). A transducer (14) transmits an ultrasonic interrogation pulse through the liquid to the reference material (20). The density of the reference material (20) is known and its boundaries are well defined. The interrogation pulse is reflected from the faces of the reference material boundaries to provide first, second and third return pulses which are used to determine the density of the liquid (18). The density determination is accomplished by determining characteristic impedances, reflection coefficients and transmission coefficients as a function of the returned pulse amplitudes.

Abstract: The contacts of an electrical switch (27), such as a magnetic contact reed switch or a magnetic contact reed relay used in a burglar alarm system, are protected from being fused together by transient current surges. This protection is accomplished by providing a normally nonconductive shunting path (28, 29) in parallel with the switch (27). The shunting path includes a voltage responsive device (29) which is biased to conduction in response to a current surge to thereby complete the shunting path and allow the current surge to bypass the switch (27).

Abstract: A heat generator comprising a quartz tube (2) containing an electric resistor (1) and a catalyst coating layer (3) comprising at least active alumina, silica and a platinum group metal, formed on the surface of the quartz tube (2) can heat a material to be heated and the catalyst coating layer (3) itself because of the catalyst coating layer (3) being provided on the surface of the quartz tube (2). The catalyst coating layer (3) surrounds the quartz tube (2) and thus efficiently absorbs heat from the electric resistor (1) by radiation and heat conductance, whereby the catalyst coating layer (3) can be heated to the activation temperature within a short time. Furthermore, the heat generator also heats air around the heat generator to much circulate the air as a convection air stream around the heat generator. When the convection air stream contact the catalyst in the catalyst coating layer (3) heated to higher than the activation temperature by heating of the heat generator, smelling components or noxious components in the air stream are oxidized and purified by the catalytic action before leaving the heat generator.

Abstract: A hinge device (22, 23) comprising a shaft (32, 132), a coil spring (31), a shaft holder (25, 125), and a bracket (33, 133, 233). The coil spring (31) has a coiled portion (35) wound around the main portion (51) of the shaft (32, 132). The shaft holder (25, 125) is secured to a first member (2) and holds one end (52) of the shaft (32, 132), thus preventing the shaft (32, 132) from rotating. The bracket (33, 133, 233) supports both end portions (52, 53) of the shaft (32, 132), and is secured to a second member (8). The bracket (33, 133, 233), therefore, allows the first and second members (2, 8) to rotate relative to each other around the shaft (32, 132). The main portion (51) of the shaft (32, 132) has a cross section having a short diameter (W) and a long diameter (H). The coiled portion (35) is formed of a plurality of turns contacting one another. Each turn extends at a predetermined pitch angle to a line which extends at right angles to the axis of the shaft (32, 132). The turn therefore looks elliptical when viewed in the axial direction, and has a short diameter (C) greater than that (W) of the main portion (51) of said shaft (32, 132), and a long diameter (D) substantially equal to that (H) of the main portion (51) of said shaft (32, 132). When the first and second members (2, 8) are rotated relative to each other around the axis of the shaft (32, 132), the coiled portion (35) is elastically deformed, changing the pitch angle and applying a frictional drag to the shaft (32, 132). This drag suppresses the rotation of the first member (2) or the second member (8).
