Abstract: A head actuator for a disc drive and storage system having a plurality of discs and a plurality of read/write heads positioned on upper and lower surfaces of the discs. The head actuator includes a plurality of load springs (33). Each load spring (33) has a plurality of through holes located at its inner end. A head (32) is mounted to the outer end of each load spring for positioning the head on the upper and lower surface of a disc (44). The head actuator further includes an integrally formed head arm assembly. The head arm assembly has a plurality of parallel head arms (31′) integrally formed at their inner ends to a main head arm body member and extended in parallel therefrom such that they can be positioned between corresponding discs of the disc drive and storage system. Each head arm (31′) is formed with a plurality of through holes (36) in its outer end for alignment with a plurality of corresponding through holes formed in each head load spring (33) at its inner end. The load springs are connected to opposite sides of the head arms using the aligned through holes of the load springs and head arms. The head load springs are sequentially connected to the head arms in an assembly method using a plurality of screws (38) for directly connecting the outer ends of the head arms to the inner ends of the load springs via two series of through holes of the head arms and the load springs (38).

Abstract: A redundant, fault-tolerant connection is provided from a local processing station (18) to a plurality of remote processing stations (20,22,24), each including an I/O bus and an associated I/O bus interface logic circuit (40,50,60). Two of the bus interface logic circuits (40,60) are connected directly to the processor interface circuit (30), via separate direct links (38,70). Intermediate bus interface circuits (50) and I/O busses of intermediate remote stations are connected between the two selected bus interface circuits, in a series arrangement including alternate link segments (46,48,56,58) and bus interface circuits(52,62). Each of the bus interface circuits has pass-through capability for transmitting data in either direction, and the links and link sections also are bidirectional, enabling transmission of data in either direction and on either path between the processor interface circuit and any of the remote stations, through any intervening stations. The processor interface circuit itself is intentionally configured without such pass-through capability.

Abstract: Separate density profiles are obtained for each station of a multi-station winder (10). The technique requires a single processor for simultaneously monitoring the density of any number of rolls (24-32) being wound. The density may also be monitored for the unwind roll (12) for determination of roll structuring changes by a winder. A simple system is provided in which each of the rolls (12, 22-32) is provided with an en­coder (44-56). The encoder (44) of a center roll (22) of fixed diameter produces a fixed number of pulses per revolution representing paper length and the pulses pro­duced by the encoders (48-56) of each of the winding stations are counted along with the pulses produced by the winder of the center fixed diameter roll (22) for computing density from roll and angular parameters and basis weight.

Abstract: Laser output radiation with reduced noise power components is generated, which can also be used to form short, stable laser pulses in the picosecond and sub-picosecond range. The low noise components are achieved by superimposing on the resonator wave in the active medium its fed-back output radiation, which is in the order of magnitude of the spontaneous radiation emission of the oscillating resonator wave.

Abstract: A system (20) and method for managing change in software systems and applications manages change for both transient and persistent objects in a domain independent, non-intrusive, object-oriented fashion. The system (20) and method are designed and implemented as a combination of two abstract machines (22,24) consisting of a set of interface functions (25,26) visible to the application, and an internal or private state (27,28) which is hidden from such application. Applications use the interface functions (25,26) to obtain the services of this change management system (20) and method. Since the internal state of such system (20) and method is outside the application, change management is provided as a service without the need for altering or adding onto application data structures and interfaces.

Abstract: The invention relates to a method of fixing blades to a rotationally symmetric blade carrier for fluid-flow machines by means of friction welding, several flat welding surfaces being provided on the periphery of the blade carrier, which welding surfaces are each welded to a flat welding surface of a blade, and the welding temperature necessary to join the bodies being obtained by pressing together the welding surfaces of blade and blade carrier by means of an upsetting force and by simultaneous translatory oscillating movement of the welding surfaces against one another. To this end, the oscillating movement is effected in a direction which lies in a plane extending essentially at right angles to the axis of the blade carrier. Furthermore, it relates to a blade for carrying out the method, a mounting fixture for friction-welding equipment for fixing blades to blade carriers, and also a friction-welding apparatus. The method has the advantage that the direction of the movement producing the heat is independent of the blade and wedge angle of the blade carrier. The number of settings which are required to set the friction-welding equipment for producing or repairing a rotor or stator is accordingly reduced.

Abstract: Material and impurity gases are introduced into a crystal growth chamber (32) to grow a crystal film on a GaAs substrate (10). A light beam emitted from a variable-wavelength light source (35) is applied to the crystal film being grown on the substrate (10) while varying the wavelength of the light beam. The dependency, on the wavelength of the light beam, of the intensity of light reflected by the crystal film is measured, and an optimum wavelength is selected for measurement depending on the type of molecules adsorbed while the crystal film is being grown. Light is then applied at the optimum wavelength to the crystal film being grown, and a time-dependent change in the intensity of light reflected by the crystal film is measured. The rate at which the material gases are introduced into the crystal growth chamber (32) is adjusted to control the growth rate of the crystal film, the composition ratio of a mixed crystal thereof, and the density of the impurity therein.

Abstract: A system for employing a computer to control a device to provide a plurality of services (207) for a plurality of entities (205). Each entity corresponds to exactly one of the services and each service has its own copy (213) of the code which defines the service. The system associates a process (113) which executes the service with each service. The code for a service defines a finite state machine which is continually executed by the service's process. While in a given state, the finite state machine may traverse a decision graph which is directly accessible to the process. Actions to be taken on traversal of a node of the decision graph may be defined in the finite state machine. The service's process communicates with other processes and with itself by means of interprocess messages. Each state of the finite state machine contains event handlers for responding to messages received by the service's process. The finite state machine is defined by a special language, the service logic language, and the decision graphs are defined by means of a graphical editor. The compiler for the service logic language produces not only C++ code defining the finite state machine, but also data base and shell scripts which are used to provision and maintain the services. An embodiment of the system is disclosed which is used in a service node of a telephone switching network to provide telephone services such as 800 number service, caller ID, and the like.
