Title: Magnetic disk device
Inventor: TAKEMORI HIROSHI
IPC: G11B5/02
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic disk device that a number of troubles is minimized while TA is generated. SOLUTION: Signals read by an MR head 1 from a magnetic disk medium 2 are AGC amplified into read waveforms (a) by an R/WIC3, decoded into read data (b) by an R/W circuit 4, error corrected by an HDD control circuit 7 and then, transmitted to a host device 9. A TA detecting circuit 5 detects TA from the waveforms (a) and transmits a TA generation notice (c) to an AGC control circuit 6 and an ECC circuit 8. If the circuit 6 receives the signal (c), the circuit 6 transmits a signal (f) to the IC3 to hold an AGC. If AGC is held during the generation of TA, the disturbance in the waveforms (a) is suppressed to a minimum and the number of errors of the data (b) is minimized. Moreover, an error correcting capability is increased because the location of an error is specified by the signal (c).

IPC: G06F11/34
Filed: 1999-12-24
Abstract: PROBLEM TO BE SOLVED: To correctly connect log information separately outputted to plural files along the time base, and to accurately grasp the order of the generation of events from the connected log information. SOLUTION: Each program 101, 102, and 103 in a software system 111 obtains a shared counter value for specifying the order of output of log information held by a shared counter 110, and outputs the value by including it in log information, and stores it in a log information file. The shared counter value obtained by the shared library 103 at the time of outputting the log information is notified through a shared counter value notifying means 108 to the program 102 calling another program (the shared library 103 in Figure), and the notified shared counter value is outputted so as to be included in the log information.  Thus, the order of output of the log information can be uniquely specified, and the relevance among the plural log information can be clarified by using the shared counter values recorded on the plural log information in the plural log information files and the notified shared counter value.

In this way, it is set at a prescribed ratio. The ventilating surface 10 of the filter 1 is installed in a position projecting from the discharge port surface part 2 by a fitting height T corresponding to an end edge part 12a of a peripheral frame.  As a result, in the discharge port surface part 2, smoke, hot air or the like can be sucked from all the effective range 'd' of the ventilating surface 10.
