Title: Dynamic pressure bearing device
Inventor: SAKATANI IKUNORI
IPC: F16C33/10
Filed: 1989-11-07
Abstract: PURPOSE:To prevent rotating accuracy from lowering due to change in torque with excellent durability maintained as well as to prevent lubricant from being splashed out by making outside grooves in a herring bone shape in the axial direction longer than inside ones while being formed into an asymmetric shape, and thereby constituting the whole shape of the grooves in such a way that lubricant is pushed inward. CONSTITUTION:In the groove pattern of the whole of grooves in a herring bone shape in radial bearing surface 10 arranged at 2 places in the axial direc tion in spaced relation, the length of each outside groove 15B in the axial direc tion is made longer than that of each inside groove 15A in the axial direction. Rotating accuracy is therefore will never be lowered due to change in torque caused by the flow-out of lubricant from the bearing surface during rotation because of its configuration in which lubricant is pushed inward. This thereby prevents a bearing from seizing with excellent durability maintained, and also prevents members and the like attached to rotating members from being contami nated.

Abstract: PURPOSE:To prevent the degradation in the OWM characteristic in the outer peripheral part of the magnetic disk by setting the angle formed by the grooves formed by texturing and the circumferential direction of the magnetic disk small on the inner peripheral side and large on the outer peripheral side. CONSTITUTION:The surface of a substrate 3 is subjected to texturing so as to have the groove shape in the circumferential direction. The cross angle formed by the circumferential direction of the magnetic disk 4 and the traveling direction of the grooves 8 formed by the texturing is set as small as 0 to 5 deg. on the inner peripheral side and as large as 5 to 30 deg. on the outer peripheral side and the intermediate cross angle is so adjusted that the angle increases gradually from the inner peripheral side toward the outer peripheral side. The traveling direction of the grooves 8, therefore, coincides nearly with the circumferential direction of the disk 4 on the inner peripheral side. The high coercive force and the goo squareness are thus obtd. On the other hand, the cross angle increases on the outer peripheral side and, therefore, the magnetic characteristics of the slightly smaller coercive force and squareness are obtd. and the OWM characteristics are improved.

Title: Fluid conduit
Inventor: ISHII DAIDO
IPC: G01N30/06
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To suppress the spread of components in the flow path direction while improving a fluid mixing efficiency by forming a conduit into a cylindrical form and a rotor as an introduced bar like form extending in the direction of a conduit, through which a fluid is conducted and rotating by centering around the extended shaft of the bar-like form. SOLUTION: A bar-like rotor 120 introduced into a conduit 110 consisting of a hollow pipe rotates using a long-size shaft of the rotor 120 as a rotary shaft and mixes a fluid flowing through the conduit 110 into the cross section direction of the conduit 110 almost without any influence in the flow path direction. As the rotor 120 is present in the center part of the conduit 110, the difference in a fluid flow between an area near the inner wall of the conduit 110 and its center part diminishes. While a solution passes through the conduit 110, a motor is activated to rotate the bar-like rotor 120 in the conduit 110 to mix the solution orthogonally with its flow so that the fluid state of the solution changes from a parabolic state to a plug current state.  Thus, it is possible to obtain a mixing effect and, at the same time, suppress the spread of the components in the flow path direction, and further, achieve an optimal mixing action constantly by changing the number of rotation following a change in the mixing state.
