Patent EP-0318443-A2 (EP)
Inventor: FENNEMA ALAN AUGUST
IPC: G11B7/09
Filed: 1988-10-14
Abstract: An optical disk recorder includes a position servo control loop for causing a beam of radiation to faithfully follow a track on the disk, jump from a current track to an adjacent track or to a small number of tracks away from the current track. Operation of the position servo loop is altered by selectively reversing the phase of a differentiated position error signal and integrating the differentiated position error signal for comparison with a sawtooth signal for moving the beam of radiation from the current track to an immediately adjacent track under continuous position servo control. Upon reaching the adjacent track, the sawtooth signal returns to a reference potential for initiating track following. The servo error between the integrated differen­tiated position error signal and the sawtooth signal is sufficiently small such that relaxation of the sawtooth signal does not cause any significant perturbations in the positioning servo loop operation. A velocity long seek servo can be substituted for the position servo loop for more rapid long seeks.

Abstract: A planar oxygen sensor has an insulating substrate (1,2), a cathode (5) formed on the insulting substrate generally at the center thereof; another electrode formed on the insulating substrate in a region other than the region of the cathode, a gas permeable membrane (7) stretched to cover these electrodes and having its peripheral portion supported on the insulating substrate, and an electrolytic solution (6) charged between the gas permeable membrane (7) and the insulating substrate (1,2). A surface of the cathode (5) is substantially in contact with the gas permeable membrane (7) and is formed at a position higher than the gas permeable membrane support portion of the insulating substrate. A portion of the insulating substrate surface other than the region where the cathode (5) is formed is recessed. Because the layer of electrolytic solution (6) on the cathode (5) is thin, oxygen molecules passing through the gas permeable membrane (7) can immediately serve for the reduction at the cathode (5), thereby increasing the response speed of the planar oxygen sensor. Also, the amount of electrolytic solution (6) is increased by the recess (10) to extend the life of the sensor.

Abstract: A computer interconnect system uses packet data transmission over serial links (A,B) connecting nodes (17,18) of a network. The serial links provide simul­taneous dual paths for transmit/receive. An adapter couples a CPU (10) or the like at a node to the serial link. The adapter includes a packet memory (34) for temporarily storing transmit packets and receive packets, along with a port processor (36) for executing the protocol. Packets of data are transferred between the system bus of the CPU and the packet memory by a pair of data movers (32,33), one for read and one for write. The packet memory is accessed upon demand by the serial link, the port processor and the data movers, using interleaved cycles. To accommodate this access upon demand without request/grant cycles, parking registers are provided to store read or write data until a later cycle, and the data rate on the packet memory port is high enough to allow ample time for simultaneous use of both channels as well as packet processing and moving to and from the CPU.

Abstract: The capacity of cache memory supported by a cache controller can be increased by offsetting the relationship between CPU address output terminals and address input terminals of the cache controller and correspondingly doubling the cache line size. In some cases, additional logic generates a hidden memory cycle so as to fetch from memory that number of bytes equal to the new line size regardless of the width of the data bus. The hidden memory cycle is initiated by a read miss and further logic generates a memory address which is not generated by the CPU. The hidden memory cycle is maintained transparent to the CPU and cache controller by inhibiting the change in a READY signal until completion of both the normal memory cycle and the hidden memory cycle.
