Title: Floating head slider and disk drive device
Inventor: YOTSUYA MICHIO
IPC: G11B21/21
Filed: 1993-11-17
Abstract: PURPOSE:To stabilize a floating amt. of the head slider by forming its surface opposite to a recording medium with rails in specified constitution and floating the slider with an airflow. CONSTITUTION:The rails 11, 12 and 13 for acting as air bearing surfaces are arranged on the lower surface of the floating head slider 10 in the middle and in symmetry to its right and left, and the tip of the individual rails are formed with tapered parts 11a, 12a and 13a. At this time, the rails 12 and 13 are formed to be opened to be air inflow side. The head slider 10 is given enough floating force by the airflow generated by the rails 12 and 13 attending upon the rotation of a magnetic disk, and its floating amt. is maintained even when its position in the radial direction of the magnetic disk is fluctuated. Moreover, since the rails 12 and 13 are inclined to the rail 11 in the directions opposite to each other, when a skew angle of the slider 10 to the tangential direction of a track on the disk is fluctuated, total floating force give to the rails 12 and 13 is maintained to be constant accordingly.

Title: Housing furniture
Inventor: TATEISHI KATSUAKI
IPC: E05D15/58
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To improve a guiding function for a door and to dissolve the play and biting of the door by providing through-holes in the base end member and the turning end member of a hinge and externally fitting the through-hole to a rod. SOLUTION: When the door is operated so as to be inclined backwards, the turning end member 22 is turned to the base end member 21 with the shaft of the hinge 2 as a supporting point. When the turning end member 22 is turned to a housing position to be flat with the base end member 21, the through-hole 22d of the turning end member 22 communicates with the through-hoel 21d of the base end member 21 in an optically viewable state. Thus, when the door is pushed in from the position towards a housing space, the rod 15 inserted inside the through-hole 21d advances inside the through-hole 22d and the turning end member 22 is pushed inside a furniture main body along with the door.  At the time, since the side edge side bent part 32 of the door is slid while being attached to the upper surface of a door supporting part, the door is maintained in the state of being supported by the rod 15 and the door supporting part from both sides at all times and guided in a depth direction along the rod 15 and the assembly accuracy of a door supporting structure is not requested.
