Title: Disk recording and reproducing device
Inventor: KURODA MASAYUKI
IPC: G11B21/21
Filed: 1989-08-16
Abstract: PURPOSE:To obtain the stable flying characteristics of a flying head by controlling the flying amount of the slider of the flying head by a change in the yawing angle of the slider. CONSTITUTION:The yawing angle theta2 of the slider 9 of the flying head 8 is increased as a discoid recording medium 4 approaches its outer periphery 20 from its inner periphery 19. Moreover, the flying force of the slider 9 is gradually decreased by a two-vane, air bearing forming surface 24. Consequently, the flying amount of the slider 9 can be controlled by a change in the yawing angle theta2, and can be almost constant from the outer periphery 20 to inner periphery 19 of the discoid recording medium 4. Thus, the stable flying characteristics of the flying head 8 can be obtained.

IPC: F16H1/32
Filed: 1993-08-27
Abstract: PURPOSE:To achieve miniatuarization, weight reduction, low cost, low noise, low vibration on the assumption that a high reduction gear ratio is obtained by internally meshing both external gears with an integrated internal gear, respectively, and rotatably supporting this internal gear by means of a casing. CONSTITUTION:Since a first external gear 110 and a second external gear 112 are ocsillating (eccentrically) rotated in the opposite direction into the center of an input shaft 102, respectively, active unbalance caused by individual oscillating-rotation is offset. Moreover, since there is not provided with a crank- like inner pin, there is few number of parts, and also there is no concern of generation of inconvenience of this part. As for the reduction gear ratio, when the rotational speed of the input shaft 102 is N1, and when the rotational speed of the output shaft 104 is taken as N2, the formula; N2={1-(S2.P1)/(S1.P2)}N1 holds. And when the value of N. is positive, the rotation in the same direction as that of the input rotation is output, while, when the value is negative, the rotation in the reverse direction to the input rotation is output.

Title: Method and jig for dividing ceramic board
Inventor: SHIGEKANE TAKESHI
IPC: H05K3/00
Filed: 1993-08-04
Abstract: PURPOSE:To reduce the rate at which a ceramic board breaks into shell-like chips by setting a fulcrum in a position facing a dividing groove on that side of the ceramic board which is opposite to the side where the dividing groove is formed, so that the fulcrum points in the direction of extension of the dividing groove and outside the side opposite to the groove. CONSTITUTION:To divide a ceramic board into chips using a dividing jig, the board 1 is first inserted into the slits 3a, 4a of right and left holding members 4,3 to hold the board 1 in place. Next, with the right holding member 4 held in position, a force in the direction of the arrow is exerted on one side end of the left holding member 3 to rotate the left holding member 3 about the rotating shaft 6 of a rotary plate 5, thereby exerting the board 1 with bending moment and dividing the board 1 into right and left chips 1b, 1a along a dividing groove 2. Since the fulcrum in this case points in the direction of extension of the dividing groove 2 and locates outside that side of the board 1 which is opposite to the side where the dividing groove is formed, the board is prevented from breaking into shell-like chips.
