摘要： In a gas dynamic pressure bearing mechanism (1) for smoothing rotary motion of a shaft (10) by feeding gas to the bearing clearance between the shaft (10) and a fixed sleeve (20) for supporting the shaft (10) through a herring bone groove (10a), the herring bone groove (10a) is provided in the shaft (10) such that pressure distribution generated in the bearing clearance moves at a high speed. The herring bone groove (10a) consists of N grooves such that N minimal pressure values appearing alternately with maximal pressure values at the positions where the maximal pressure values of dynamic pressure variation appear in the bearing clearance when the shaft (10) rotates have such an interval as it becomes lower than the condensation pressure value.

摘要： An optical deflector is provided with a scanning mirror which is rotatable about a shaft and accompanied by a sleeve and hub. The pneumatic pressure around the mirror which is located within a cavity formed by a motor case of the deflector is maintained lower than an inside pneumatic pressure of a pneumatic pressure creation arrangement. The arrangement has the shaft provided with herringbone grooves engraved on the periphery thereof and the sleeve rotatable about the shaft together with the hub and the scanning mirror. When the scanning mirror rotates about the shaft, windage loss may be reduced, and when the inside pneumatic pressure between the shaft and the sleeve is kept higher than the atmospheric pressure, the rigidity of the shaft may be maintained during the rotation of scanning mirror about the shaft.

摘要： A plurality of first memory blocks and a second memory block for reproducing data of the first memory blocks are formed. When a read command and a refresh command conflict with each other, a read control circuit accesses the first memory block according to the refresh command and reproduces read data by using the second memory block. When a write command and the refresh command conflict with each other, a write control circuit operates the memory block according to an order of command reception. Therefore, it is possible to perform refresh operation without being recognized by users. Namely, a user-friendly semiconductor memory can be provided.
