Title: Data transfer device, disk drive, and data transfer method
Inventor: SATO MASAHIKO
IPC: G06F13/38
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To permit high-reliability data transfer and a minimum throughput decrease by controlling data transfer to a 2nd data transfer speed slower than a 1st data transfer speed once an error detecting means detects a specific error. SOLUTION: A hard disk drive(HDD) is equipped with a hard disk controller 105A which controls operation for reading and writing data out of and to a magnetic disk 101 and an MPU 106 which controls the operation of the whole HDD. To transfer data from the HDD 100 to a host 200, the 1st data transfer speed is set first and the data are transferred from the HDD to the host 200 at the 1st data transfer speed. If a specific error is detected in the transferred data, the data transfer speed is changed to the 2nd transfer speed slower than the 1st transfer speed. Consequently, the state of the IDEI/FBus can be known by monitoring the status of the existent CRC error, so high-reliability data transfer for reading can be performed only by alterations of the drive side.

Title: Optical angular velocity sensor for rotation
Inventor: KUMAGAI TATSUYA
IPC: G01C19/72
Filed: 1989-08-02
Abstract: PURPOSE:To measure the rotating speed of the earth by cutting off light which is incident on a sensing loop, and setting the zero-angle signal of subsequent rotational angular velocity detection of a signal processing circuit from a signal obtained from a photodetector currently. CONSTITUTION:The signal processing circuit 7 finds the rotational angular velocity from the ratio of, for example, a phase-modulated frequency component and a secondary harmonic component, but a certain offset voltage is generated because of the performance of an electronic component at the time of the synchronous detection of each frequency component. Here, the light incident on the sensing loop 5 is cut off at the time of sensor actuation to obtain the function of a sensor, and then only the offset voltage is detected. For the purpose, the zero-angle signal of a reference potential is only set and then offset voltage can be removed even during the rotation of the body to be measured. Consequently, the rotating speed of the earth can be measured.
