IPC: G06F3/06
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To execute continuous writing into storage devices for at least two pieces of different information storage devices using the same storage device for protected information for storing protected information in a short time by avoiding the increase of the burden of the cost in the redundant array of the storage device. SOLUTION: When these is a preceding request 1, CPU 11 reads old data from HDD 6 and old protected information from a silicon disk unit 15 and when a request 2 occurs continually, CPU 11 reads old data and old protected information corresponding to this request. As the accessing speed of the silicon disk unit 15 is higher than that of HDD 16 in this case, the reading of old information concerning the request 1 is finished earlier than that of old data. Consequently, old data and old protected information concerning the request 2 can be started before the finish of the reading of old data concerning the request 1.

Title: Static pressure gas bearing device
Inventor: KOSAKA SOICHI
IPC: F16C32/06
Filed: 1987-07-01
Abstract: PURPOSE:To establish the high speed rotation without whirling by obliquely providing a charging hole of a radial bearing in a direction counter to a rotational direction of a shaft, and also obliquely providing a charging hole of a thrust bearing in a direction identical with the rotational direction of the shaft. CONSTITUTION:A charging hole 6 of a radial bearing 4 is obliquely provided in a direction counter to a rotational direction R of a shaft 3, so that the rotation of the shaft 3 is affected by a wedge-shaped gas film from the charging hole 6, thereby preventing the whirling. At the same time, a fine torque in the direction counter to the rotational direction R of the shaft 3 is applied thereto by the charged gas. On the other hand, a charging hole 23 of a thrust bearing 21 is provided in the same direction as the rotational direction R of the shaft 3, so that a charged gas from the charging hole 23 generates a torque in the same direction as the rotational direction R of the shaft 3. Therefore, the fine torque by the charged gas from the charging hole 6 is canceled by the torque by the charged gas from the charging hole 23. Thus, high speed rotation without whirling can be obtained. Further, in stopping the rotation of the shaft, reverse rotation may be prevented. At this time, damage of the bearing due to erroneous stop of pressure supply may be prevented.
