Title: Magnetic disc drive system
Inventor: SEINO KEIICHI
IPC: G11B5/55
Filed: 1987-12-15
Abstract: In a magnetic disc drive system including a magnetic head (51), an actuator (52) for moving the magnetic head, a control current detection circuit (55) detecting a control current (ICNT) flowing through the actuator, a position signal generation circuit (56) generating a position signal of the magnetic head, a speed control unit (57, 59, 62, 54) effecting a seek control, and a position control unit (58, 54) effecting a fine position control after completion of said seek control, the magnetic disc drive system includes units (18, 10, 11, 12, 13, 14), which, immediately upon receipt of a power supply and before receipt of a seek command, measure one or more position offset values along one or more cylinders on a magnetic disc by detecting the control current from the control current detection circuit when the position of the magnetic head is controlled under the fine position control, and calculating one or more offset corrections values and outputting the calculated offset correction values to the speed control unit and the position control unit. 
     The magnetic disc drive system may further include an automatic speed control gain adjustment unit, which after completion of the offset correction value calculation, determines a speed control gain used in the speed control unit by seeking the magnetic head at a predetermined cylinder under application of the calculated offset values and measures a time for the seek which meets a requirement of a reference seek time.

Abstract: The present invention relates to a device for the separation of particulated solids from a pressurized fluid, in particular from a viscous mass of a thermoplastic material, with a cleaning system for the filtration element based on the so-called "return pressure" principle. 
     Said device essentially comprises a body having a fluid inlet conduit, two filtration assemblies that are connected to two conduits flowing together into an outlet conduit, and a flow-dividing valve that in rest position connects the inlet conduit with the separation conduits through the filtration assemblies, whilst in the cleaning position for one of the filtration assemblies the inlet conduit is connected with the other filtration assembly, thus causing part of the fluid that has been separated by this filtration assembly to pass with counterpressure through the filtration unit that is in the cleaning stage and through a discharge outlet housed in a compartment of said valve. 
     In a similar manner the cleaning of the other filtration assembly is performed.

Abstract: An audio amplifier of the type including circuitry (30) to detect clipping and adjust the gain of an amplifier input element to control the clipping in closed loop operation further includes circuitry (48) effective to sense the temperature of an amplifier component and change the amplifier bias voltage (V/2) that determines the maximum non-clipping voltage so as to induce clipping in the audio amplifier when the temperature exceeds a predetermined temperature. The clipping control circuitry then reduces the input gain to the audio amplifier to control the clipping and, in so doing, reduces power dissipation to a level allowing the temperature to decrease to the predetermined temperature. The circuit provides for closed loop control of amplifier temperature in marginal temperature situations with minimal intrusion on the music reproduction process.

Abstract: The invention relates to a method and apparatus for on-machine winding of a web, in which a Pope reeling drum (10) is used, over which the web (W) to be wound passes. A reel spool (11) is driven by so-called centre drive. New reel spools (11′) are brought into connection with the reeling drum, after which the web (W) is conducted away from a fully wound roll to be wound onto a new reel spool. The method comprises, in combination, the following steps: an empty reel spool (11′) is brought into the grip of primary arms in such a way that bearing members (25) at both ends of the reel spool (11′) are being supported by guiding elements at each end of the reeling drum (10) in such a manner that the outer shell of the reel spool (11′) is not engaged with the reeling drum (10). The empty reel spool (11′), preaccelerated to winding speed, is brought into nip contact with the rotating reeling drum (10), the web (W) to be wounded running through the nip. Due to said nip contact, or only after it, the web breaks off or is severed by means of a double-sided adhesive tape wrapped round the reel spool (11′), whereby the web (W) begins to wind onto the empty reel spool (11) and the winding is continued by centre drive of the reel spool (11) and/or nip drive until the roll is fully wound, after which the above steps are repeated.

Abstract: Areas in an optical disk (101) are classified into three kinds of areas: file areas, used areas, and erased areas. An erasing process to convert the used area into the erased area is executed asynchronously with a writing process, thereby preventing the decrease in data transfer speed due to the erasing process upon writing process. On the other hand, the file areas, used areas, and erased areas are managed on every continuous areas which are designated by the head position and the size or end position of the area. The file is preferentially assigned to the erased area or used area of a large size. With such a construction, the area management such as an integration of the erased area or the like can be performed and the file can be assigned to the continuous areas and the access speed can be improved.

Abstract: A method and an apparatus which delay initiation of a shut down procedure in a computer to allow the riding through of variations in a power supply. An interrupter receives and interrupts an asserted shut down signal and outputs an interrupt signal when the shut down signal has been asserted. A gate trigger is coupled to the interrupter and triggers an energy booster to raise the power supplied to the computer when the gate trigger receives the interrupt signal from the interrupter. The amount of energy remaining in the energy booster is monitored by a monitor and a depletion signal is outputted when the amount of energy remaining in the energy booster is below a reference value. An output stage has inputs coupled to the interrupter and the monitor, and receives at these inputs the interrupt signal and the depletion signal and outputs a re-asserted shut down signal to the computer when both the interrupt signal and the depletion signal are present at the inputs of the output stage.
