Title: Prefix search tree with partial key branching
Inventor: NICKEL STEVEN P
IPC: G06F17/30
Filed: 1990-09-03
Abstract: A prefix index tree structure for locating data records stored through keys related to information stored in data records. Each node includes a prefix field for a prefix string of length p of the longest string of key characters shared by all subtrees of the node and a data record field for a reference to a data record whose key is completed by the prefix string. A node may include one or more branch fields when the prefix string is a prefix of keys stored in at least one subtree of the node, with a branch field for each distinct p+1 st  key character in the keys, wherein each p+1 st  key character is a branch character. Each branch field includes a branch character and a branch pointer field for a reference to a node containing at least one key whose p+1 st  character is the branch character. Each node further includes a field for storing the number of key characters in the prefix string and a field for storing the number of branch fields in the node. Also disclosed are methods for constructing and searching a prefix index tree of the present invention, and for inserting nodes into the tree and deleting nodes from the tree.

Abstract: A self-advancing film cassette has one separation claw for separating a film leader from a roll of film. This separation claw is disposed within a cassette shell so that it will contact with the outermost peripheral surface on the outer side of an area where a picture frame is to be formed. The separation claw has such a configuration as that the contact position between the tip thereof and an end face of a film leader end is 1/3 or more of the film thickness when measured from the outer surface of the photographic film. The film leader projects most at a portion corresponding to the separation claw, and the film leader is formed narrow in width so that it will not be stuck to the film roll. In the embodiment of the present invention, the film leader is subjected to deformation treatment of its corrugation or to rigidity increasing treatment.

Abstract: The machine for the continuous production of polyurethane foam panels lined with outer layers has two endless conveyor belts, defining a mould cavity between them, and a lining gantry, on which there are arranged two mixing heads (11, 12), which can be moved independently of each other into a production position above the lower conveyor belt or the lower outer layer. To each mixing head there leads a component supply line (14, 15) from the metering station 13. Provided between the two component supply lines is a permanently open connecting line (16). In the foaming position, the mixing heads preferably oscillate transversely to the direction of production. According to the invention, it is possible always to have one mixing head in operation when the other is being cleaned or maintained. It is not necessary to interrupt production for this purpose. The component lines are connected in such a way that, when changing over, no metering errors occur due to pressure fluctuations. If one mixing head is switched off, each component continues to flow through the corresponding supply line to this switched-off mixing head, but instead of flowing into it flows into the connecting line and on to the other mixing head. Consequently, there is a permanent throughflow through each component supply line to each mixing head, irrespective of whether the mixing head is switched on or not. The direction of flow through the connecting line depends on which mixing head is switched on (Fig. 2). <IMAGE>

Abstract: A start of plot mark (111) consists of three portions, a first (111a), second (111b) and third (111c) portion each of equal area with the first and third portions being above a reference line (114) and spaced from each other by the second portion which is below the reference line. The first and second portions are used to generate a reference signal for use in measuring the zero crossing of the output signal from the start of plot mark thereby to automatically compensate for uncertainties in the zero crossing such as those uncertainties produced by differences in intensities of the start of plot coloration versus the background coloration of the print medium, differences in reflectivity and illumination of the print medium, and imbalances between sensor output signals.

Abstract: A magnetron sputtering method and apparatus employing a target having an inwardly facing portion close to and surrounding the outer edge of a stepped wafer provides a sputtering surface with areas facing the differently facing surfaces of the wafer steps. Two concentric erosion zones on the target surface are independently energized at different electrical parameter values by synchronizing the power applied to the target with switched activation of plasmas overlying the respective target regions which define the erosion zones. The electrical parameters and the geometry are established so as to uniformly coat the differently facing surfaces of the stepped wafer. During part of the duty cycle during which each target region is energized, parameters may be measured. Such parameters may be those which vary with changes in geometry as for example may be due to target erosion. The operation of different target regions, such as the duty cycles or power levels for such regions, may be separately varied in response to the measurement or otherwise, to maintain uniform substrate coating as the target erodes. The target is thicker under the outer region and has an annular pole piece embedded to reduce the space separating the target erosion regions, and includes means to cool the target and reinforce it against thermal expansion.

Abstract: A safety method is provided for use with control systems for vehicles such as trucks, and in particular for electromechanical controls (10) that assist the driver in shifting the gears (12), operating the clutch (16), and in actuating the throttle (22, 24, 26) by remote control. The method, which is for use in a vehicle's throttle-actuator subsystem (26A), utilizes a transmission control processor (42A) and a throttle control processor (42B). 
     The method ascertains whether, when the driver of the vehicle removes his foot from the accelerator pedal (24A), control of the fuel pump (26C) returns to the idle governor as it should. The flow of fuel is stopped if it does not return properly. Also, a method is provided that monitors the throttle actuator (26A) to insure that it accurately follows throttle commands such as the position of the accelerator pedal (24A).
