IPC: G11B5/55

Abstract: A disk file digital servo control system utilizes a state estimator wherein the voice coil motor (VCM) (40) current is modeled, rather than measured, thereby eliminating the need for analog-to-digital conversion of the actual VCM current. The VCM current is fed back directly to the input to the power amplifier (42) where it is summed with the control signal output. This effectively changes the integrating power amplifier into a low pass filtering power amplifier, with linear input-output characteristics. Thus, during track following or short seeks, the VCM current is estimated based on this linear model. During long seeks, when the power amplifier is saturated, the VCM current is modeled based upon the known VCM characteristics during saturation, which include the effects of the back electromotive force and the coil current rise time. The microprocessor (50) in the digital servo control system determines which VCM current model to use by a determination of when the power amplifier is in saturation. In the preferred embodiment, the microprocessor determines power amplifier saturation based upon a value of the head velocity error, which is the difference between the commanded velocity and the estimated velocity.

Abstract: A phase lock/frequency control loop includes a voltage-­controlled oscillator (10) operating within a predetermined microwave frequency band and phase-locked to a reference oscillator (24) operating at a reference frequency below microwave frequencies. An offset loop signal is developed by an offset mixer (12) heterodyning the voltage-controlled oscillator (10) output signal with an offset microwave signal from an offset generator (14) whose frequency is located at the center of the predetermined microwave frequency band of the voltage controlled oscillator (10) to form a signal at an intermediate frequency (I.F.) within the frequency range of a programmable digital frequency divider (20). A phase/frequency detector (26) produces an error signal having a magnitude representative of the difference between the output from the divider (20) and a reference signal from a reference oscillator (24). The polarities of the error signal supplied, through an amplifier (30) and filter (32) to the voltage controlled oscillator (10) are set in accordance with whether the frequency commanded by a decoder (22) controlling the divider (20) is above or below the offset frequency. The signal frequency offset technique increases the frequency range of the indirect frequency synthesizer to twice the highest operating frequency of the programmable digital frequency divider.

Abstract: Method and apparatus for reducing call setup time for calls to Advanced 800 customers by eliminating one database query. (Toll charges for 800 calls are paid by the called customer.) In the prior art, a call to an Advanced 800 customer required accessing a Basic 800 database, then, using data obtained therefrom, accessing an Advanced 800 database. In accordance with this invention, a table of the most frequently called Advanced 800 numbers and the corresponding data normally obtained from the Basic 800 database is dynamically maintained in each toll switching system. When an 800 call is received at a toll switching system, the table is examined to see if the Advanced 800 service accessing data is stored therein. If so, the advanced 800 database is directly accessed without first accessing the Basic 800 database; ifnot, the call is processed as in the prior art, plus updating the table if the call is to an Advanced 800 customer. Advantageously, such an arrangement reduces call setup time to frequently called Advanced 800 customers by about 1.5 seconds.

Abstract: An improved method for dynamically and centrally managing a teleprocessing network partitions the network into Focal Point (FP) nodes (10, 14) and non-FP (NFP) or serviced nodes (12, 16, 18, 20). Each FP node (10) provides man­agement services to an assigned group of non-FP nodes. The names of the non-FP nodes are maintained in a table called a "sphere of control" (SOC) table at the FP node that services those NFP nodes. As NFP nodes in the SOC table become active, the FP establishes a session with the NFP node and sends it a "Request to be Your FP" message. If the NFP node supports the keys (bit pattern identifying a particular category of management services data) for which authorization is being requested, the NFP node replies positively acknowledging the requestor as its focal point for the specified key. Thereafter, problem messages which are related to the particular type of management services are forwarded to the FP node.

Abstract: The working cylinder without piston rod is designed as a band cylinder, the band (3) in the cylinder covers (8) passing through a location chamber (10) for a sealing member and a guide member. The sealing member consists of a strip-like sealing element of elastic material on either side of the band, which sealing element can be designed as a lip seal on the piston side. The sealing elements (12, 13) are inserted into the location chamber (10) with elastic tensioning towards the band (3). The guide member arranged remote from the piston relative to the sealing member has a web-like guide element (23, 24) on either side of the band (3), which guide element (23, 24) is likewise pressed elastically against the band (3) by the tensioning of the sealing elements (12, 13). By means of stop surfaces (28), the guide elements (23, 24) end with a clearance gap (29) in front of the wall (15) of the location chamber (10). The result of this is that the band (3) can be elastically deflected from its desired position only by the clearance gap (29), positive-locking support of the guide elements (23, 24) on the cylinder cover (8) is then effected, and thus no further band deflection is possible.

Abstract: An image recording apparatus for recording an image of an original on a developer sheet with the use of a microcap­sule, in which the developer sheet and the microcapsule sheet having a surface coated with immense number of photo­sensitive and pressure-rupturable microcapsules are subject­ed to pressure development by a pair of pressurizing roll­ers. To ensure that the pressure development is performed under the condition where the developer sheet and the micro­capsule sheet are superposed one on the other, the nip and retract timings of the pressurizing rollers are determined properly according to the present invention. For example, the developer sheet is conveyed at a speed asynchronous with the microcapsule conveying speed and the conveyance of the developer sheet is stopped after its leading edge is intro­duced between the rollers held in spaced apart condition. The rollers are brought to the nip position to thereby start the pressure development when the exposure start line on the microcapsule sheet is in alignment with the leading end of the developer sheet. The retract timing is determined, for example, depending upon the size of the developer sheet.
