Title: Disk drive device
Inventor: ICHIYAMA YOSHIKAZU
IPC: G11B19/20
Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To prevent a thrust dynamic pressure bearing from faults due to sliding in contact by effectively utilizing a characteristic of an air dynamic pressure, having small rigidity variation over a wide temperature range. SOLUTION: Since a thrust oil dynamic pressure bearing part 11b is operated by an oil dynamic pressure, required bearing rigidity is obtained even in the case of rotation at a low speed as compared with an operation by an air dynamic pressure as well as a fault owing to sliding in the thrust dynamic pressure bearing part is prevented. Also, since a radial air dynamic pressure bearing part 11a is operated by the air dynamic pressure, not only is a sealing structure such as a lubricating oil unnecessary, but its constitution becomes simple. Furthermore, since air is not exhausted, the shortage of lubricating fluid is dissolved, and the radial air dynamic pressure bearing part is also advantageous in terms of the service life.

Title: Multiple contact connector
Inventor: OISHI SHIGEO
IPC: H01R35/04
Filed: 1989-12-19
Abstract: PURPOSE:To prevent any breakdown of a contact in inserting or drawing by connecting a contact housing to a pin housing turnable and in such a manner that a turn angle can be fixed. CONSTITUTION:When a contact housing CH5 and a pin housing PH6 are fixed in an arrangement in the same direction, they can be mounted as they are fixed thus preventing an increase in number of component parts or manhours. When a cable and a corresponding printed board are arranged in the different direction, the housings PH6 and CH5 are turned in separation from each other or turned by a strong force so that the housing CH5 is disposed toward the desired direction. The housing CH5 is held by a certain force in the desired direction. Therefore, deterioration in operability caused by the unnecessary turn of the housing CH5 and possibility of breakdown of the contact can be prevented when the cable or printed board is inserted into or drawn from a connector.

Title: Improving method of surface morphology of laser irradiating surface
Inventor: MUKAI RYOICHI
IPC: H01L21/3205
Filed: 1989-12-20
Abstract: PURPOSE:To improve the deterioration of surface morphology by conducting irradiation of pulse energy density, just enough to melt the whole conductive film, in superposition irradiation and performing the irradiation of pulse energy density, just enough to melt substantially whole surface layer in the irradiating region after the irradiation. CONSTITUTION:Al 2 is melted completely, and the surface of Al 2 is superposition-irradiated in extremely weak energy density (1-2J/cm<2>) in an extent that the surface of Al 2 is melted slightly. Since Al 2 on the interface of a foundation SiO2 layer 3 (Fig. (a)) is not melted by a laser at that time, no nucleus 4 is formed. A solidified nucleus is also generated in Al melted through re-irradiation, but directional solidification promotes around the nucleus, and a large quantity of melten Al flow into a recessed section 5 (Fig. (a)) at a time earlier than completion. Accordingly, the deterioration of surface morphology is improved, and the smooth surface (Fig. (b)) 2 can be acquired.
