Abstract: A switching error detection and recovery mechanism recognizes that an I/O configuration has changed. Comparing new configuration data to previous data maintained in a CDT table structure, and detecting unequal path information, an error condition is recognized. After recognizing the error condition, recovery actions are taken to notify the operator and insure data integrity. The CDT is structured so that redundant data is eliminated, and so records may be efficiently and dynamically added and deleted.

Abstract: The invention relates to a process for improving the surface characteristics of steel sheets which have a corrosion coating of an aluminium/zinc alloy. Experience has shown that the surface of these sheets is nonuniform, so that subsequent even coating is not directly possible. However, in order to render the surface sufficiently uniform to permit coating to be carried out, zinc dust is blown into the coating before it has solidified, the zinc dust suppressing the formation of a structure. <IMAGE>

Abstract: An eddy current type system connected to an output shaft (1) of a transmission of a vehicle comprises a rotor (5) connected to the transmission shaft (1), a stator (11) movable relative to the rotor (5) and a magnet (13) mounted on the stator (11). The rotor (5)has a ferromagnetic part (7) and a non-magnetic or feeble-magnetic part (8). The magnet (13) of the stator (11) can move in the vicinity of the ferromagnetic part (7) of the rotor (5) to allow an eddy current to flow in the rotor (5). The magnet (13) also can move in the vicinity of the non-magnetic or feeble-magnetic part (8) of the rotor (5) to prevent the eddy current from reaching the rotor (5). Therefore, when the magnet (13) is moved in the vicinity of the ferromagnetic part (7), a brake force is applied to the rotor (5) whereas when the magnet (13) is moved in the vicinity of the non-magnetic or feeble-magnetic part (8), the brake force is no longer applied to the rotor (5).

Abstract: In an electrostatic spray coating apparatus (10), liquid coating material is applied to a workpart inside of a spray booth (12). Alternating flows of liquid coating material, liquid solvent and air are conducted through various internal flow passages in a conduit (14) inside the spray booth. An electronic differentiator (24) is positioned adjacent a predetermined location along the conduit (14) and energized from an electrical source disposed outside of the spray booth (12) to differentiate between liquid and gas in the internal flow passage for nonintrusively detecting when the head of liquid flow reaches the predetermined location along the internal flow passage. This is accomplished by an electromagnetic field extending into the flow passage and sensing the changes in the electromagnetic field resulting from dielectric differences between liquid and gas in the flow passage.

Abstract: In a packet network, each data packet that is transported through the network to a destination node is assigned one of 2 N  priority levels (CS) based on the type of information contained in the data packet. A data packet containing system control information is assigned the highest priority level. A data packet containing, for example, user information, is assigned a lower priority level. In addition, each priority level is associated with a respective "watermark" threshold (310,315,320,325). When a data packet arrives at a network node, the node compares (340) the packet's associated watermark threshold with the number (350) of data words currently stored in a common memory (380). The node rejects the packet if the watermark threshold is found to be less than that number to reserve space in the memory for data packets of higher priority. Otherwise, the data packet is stored in the common memory.

Abstract: A secondary ion mass analyzing apparatus is suitable for a depth directional analysis of a specimen (15). The apparatus includes means (18, 19, 31, 32) for forming an image of said secondary ions (7), an aperture (20) disposed on a position in which the secondary ion image is formed, means for detecting the secondary ions which have passed through the aperture (20) and for converting the detected ions into electrical signals, and means (30) for displaying an image of said aperture (20) based on the electrical signals (e s ). In such a manner, the aperture (20) is disposed on the secondary ion image forming position. The image of the aperture is displayed on the image displaying apparatus (30) by using the secondary ions (7) which have passed through the aperture (20). If the ion image is not formed on the position of the aperture (20), the contour of the aperture image would be unclear while if the ion image is formed on the position of the aperture, the contour of the aperture image would be clear. Accordingly, by monitoring the clearness of the aperture image, focusing of the ion image upon the aperture position may be determined. Therefore, the secondary ions (7) which have generated from the specimen (15) corresponding to a portion other than the central portion of the primary ion beam (1) can be prevented from being introduced to a mass analyzing   portion. A depth directional analysis of the specimen (15) can be accomplished at a high accuracy.

Abstract: A sealing strip 30 for sealing between a flange 26 running around a door opening in the vehicle body and the door 28 itself comprises a channel-shaped gripping part 6 which firmly embraces the flange 26 and which supports a soft sealing part 8. The sealing part 8 has an internal wall 36 to prevent it being distorted by the closing door 28. However, by arranging for the wall 36 to extend diagonally between the plane of the flange 26 and the plane of the door 28, the amount of the partially compressed rubber which becomes folded up in the gap A when the door is closed is much less than would be the case were the wall to be parallel to the flange, and this reduction in the amount of rubber makes for easier closing of the door.

Abstract: A data card (7) is produced by hot-moulding a mixture of powdered polycarbonate with carbon black, the latter being in a proportion of 8 ppm relative to the thermosetting base material. The inside surface of the mould wall that produces the front of the card (7) is scored, the distance between the troughs, and likewise of the peaks, of the scoring being a multiple (2 to 3) of the wavelength of the laser beam subsequently used in applying the contrasting marks to the card. A lasing tube (9), controlled by a control unit (10) comprising a programme containing the indications to be produced on the card, is used in order to direct a laser beam onto the card. The infrared radiation is absorbed by the carbon black contained within the card substance which heats up. This produces a colour change causing the appearance of the marks, such as a signature (12) and a photograph (13).

Abstract: The invention provides an apparatus for processing silver salt photosensitive material with a small amount of processing solution. The processing solution uniformly reacts with the photosensitive material for maintaining high processing quality. 
     The apparatus of the invention includes: a process tank 96 which is relatively small in volume; and a developer supply roller 98 which is partly soaked in the processing solution. New or unused developer is temporarily stored in a temporary reservoir 100 formed on the circumference of the roller, held in pores of sponge formed on the surface of the developer supply roller, and supplied to an inlet of photosensitive material PM in the process tank 96 with rotation of the roller 98. The new processing solution is uniformly diffused, along the width of the photosensitive material PM, in the vicinity of the inlet in the stored processing solution. Accordingly, the photosensitive material PM is evenly and efficiently processed. 
     The invention allows smaller equipment as well as improvement of processing quality. Furthermore, the smaller volume of processing solution prevents accumulation of sludge, thus saving time and labor for maintenance.
