Abstract: The present invention provides a microwave plasma processing method capable of processing an object layer having a minute configuration and a laminated object layer without producing any etch residue and of increasing the ratio of the etching selectivity of the object layer to those of a mask and the underlying layer when etching a laminated film. The intensity of a magnetic field created by solenoids surrounding a plasma processing chamber is varied to vary the distance between the object surface of a workpiece and a flat resonance region for etching an object layer and for overetching the object layer to vary the position of a plasma produced by the interaction of an electric field created by a microwave and the magnetic field created by the solenoids.

Abstract: An image information transmitting/receiving apparatus for time and cost-saving repetitive transmission. In facsimile communication, image data where further information is added to previously-transmitted image data is often received. In the present apparatus, the original image data is stored, and only difference data from the original image data is transmitted, thus the whole image can be reproduced at the receiving side, using the received difference data. Upon transmitting the difference image information, identification information identifying the difference image information is added to the difference information, and the entire image data to be received by the receiving side is stored. Upon receiving the difference image information, the received difference information is combined with the stored image data, and an image is reproduced based on the combined image data. Further, the image data used for image reproduction is stored as original image data for the next transmission. In this manner, once the original image data is stored, only difference data is sent at each subsequent transmission, thus reducing the amount of transmission data.

Abstract: A data processing system (10) is disclosed which includes a first processor (20) having an m-byte data width, an n-byte data bus, where n is less than m, and a second processor (28) electrically coupled to the bus which performs bus transactions utilizing n-byte packets of data. An adaptor (22) is electrically coupled between the first processor (20) and the bus which converts n-byte packets of data input from the bus to m-byte packets of data, and converts m-byte packets of data input from the first processor (20) to n-byte packets of data, thereby enabling the first processor (20) to transmit data to and receive data from the bus utilizing m-byte packets of data. In a second aspect of the present invention, a method and system are provided for arbitrating between two bus masters having disparate bus acquisition protocols. In response to a second bus master (38) asserting a bus request when a first bus master (20) controls the bus, control of the bus is removed from the first bus master (20). Thereafter, in response to a signal transmitted from an arbitration control unit (50) to the first bus master (20) instructing the first bus master (20) to terminate its bus transactions, control of the bus is granted to the second bus master (38). In response to the second bus master (38) terminating its bus request, control of the bus is granted to the first bus master (20) and a signal is transmitted from the arbitration control unit (50) to the first bus master (20) acknowledging the grant of control.

Abstract: An appts. separates light fluids from heavier fluids in a chamber (15) from which a main flow path (16) and an intermittently-operated supplementary flow path (17) convey fluid to a heavy fluid outlet (18). The main flow path (16) has an outlet threshold (27), the upper rim (28) of which determines the minimum fluid level in the vessel (10). The supplementary flow path (17) has an overflow chamber which is linked to the separation chamber (15) by a light fluid inlet (33).

Abstract: According to the present invention, plural downstream side evaporation passages (21) in a downstream side heat exchanging unit (2) are divided into two groups substantially at the middle of the width by a separator (27), plural upstream side evaporation passages (31) in an upstream side heat exchanging unit (3) are divided into two groups substantially at the middle of the width by a separator (36), and a downstream side lower tank (23) and an upstream side upper tank (32) are communicated by a communication passage (44) so that inefficient heat exchanging areas of the downstream side heat exchanging unit (2) and the upstream side heat exchanging unit (3) disposed one after the other with respect to the flowing direction of air may not overlap with each other. Since the inefficient heat exchanging area in the downstream side heat exchanging unit (2) and the inefficient area in the upstream side heat exchanging unit (3) are disposed symmetrically with each other, the temperature distribution of air blown out from the refrigerant evaporator (1) is prevented from being biased, and air having a uniform temperature distribution can be produced by the refrigerant evaporator (1).

Abstract: A fuse link 16 is formed of a portion of a top level of patterned metal conductor in a multilevel conductor integrated circuit 10. A deposited layer of oxide material 26 covers the fuse link. Radiant energy from such as a laser 36 is directed through the oxide material 26 to heat and open the fuse link 16. Layers of deposited protective oxide 28 and PIX 30 then cover the fuse link and layer of oxide material. One photoprocessing step is avoided by locating the fuse link 16 and bond pad 22, both made from the top layer of conductive material, at different levels. The blanket etch then exposes the bond pad 22 while leaving the fuse link 16 covered. The fuse link can be formed down in a step 38 or the bond pad 22 can be formed above such as a group of memory cells 80. The bond pad 22 and fuse link 16 also can be formed at the same level with other process procedures.

Abstract: A compound shaft for a three journal bearing turbomachine is disclosed which includes a first stiff shaft supported by two journal bearings, a second stiff shaft supported by one journal bearing and by one bi-directional thrust bearing, and a flexible disk shaft that operably connects the first and second stiff shafts. The flexible disk shaft utilizes a flexible disk to function as a low hysterisis joint in parallel with a non-linear trunion clock spring such that the flexible disk shaft transfers overturning support from the first stiff shaft to the second stiff shaft and transfers thrust bearing support from the second stiff shaft to the first stiff shaft The flexible disk shaft allows the compound shaft to tolerate extremely large misalignments of the three journal bearings from a strait line axis. The dynamic characteristics of the compound shaft (especially the axial location of the flexible disk of the flexible disk shaft) are utilized to tune the frequencies of the turbomachine's rigid body and flexural criticals. All rigid body critical frequencies can be set below twenty percent of the machine's maximum operating speed and all flexural critical frequencies can be set more than thirty five percent above the turbomachine's maximum operating speed. When the compound shaft is supported by compliant foil hydrodynamic fluid film bearings (both journal and thrust), all negotiated rotor criticals can be extremely well damped (dimensionless damping coefficient Q of less than 2.5) and all criticals (both negotiated rigid body criticals and unnegotiated flexural criticals) need not be balanced.
