Title: Hydrostatic bearing device
Inventor: OGUSHI SHIGETO
IPC: F16C11/06
Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To prevent generation of uneven bearing clearance, wear and seizure of a bearing caused by unevenness by constituting a device so as to change press-contact force between a tapered surface on the side of a taper ring and a tapered surface on the side of an outer race by advancing and retreating amount of a screw of the taper ring. SOLUTION: By advancing and retreating a screw screwing an outside taper ring 5 and an inside taper ring 6, press-contact force among an inner peripheral tapered surface 5a of the outside taper ring 5, an inner peripheral tapered surface 6a of the inside taper ring 6 of a taper reverse to this tapered surface 5a, an outer peripheral tapered surface 3b of an outer race 3 and an inside taper ring 3a of a taper reverse to this tapered surface 3b can be changed. Because elastic deformation amount of the outer race 3 is changed and radial clearance of an outer periphery of an inner race 4 and the outer race 3, that is, upper clearance 11 and lower clearance 12 is adjusted by changing press- contact force, tightening amount of the tapered surface uniform in the radial direction can be imparted over the tire periphery and clearance can be made uniform.

Title: Weld nut
Inventor: NIWA YASUHIRO
IPC: F16B37/06
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To improve assembling workability of a bolt, regardless of plate thickness of a planar member, by providing a recessed part performing a guide so as to match axes of a bolt and a nut on a welding surface side with a planar member of the nut and making the recessed part have a depth that a screw part tip of a bolt reaches the inside of a passing hole beyond a surface of the planar member. SOLUTION: This weld nut 1 is welded concentrically with a passing hole 21 on a rear surface of a steel plate 2. A circular recessed part 12 concentric with a screw hole 11 of the nut 1 is provided. When a bolt 3 to be fastened with a screw is inserted into the recessed part 12 from the hole 21, a bolt axis is constituted so as to match with a nut axis. An additional value of at least a depth (s) of the recessed part 12 and plate thickness (t) of the steel plate 2 is made larger than a height (h) of a chamfering part 32 at a tip of the bolt 3. As a result, a tip of a screw part 31 of the bolt 3 enters into the hole 21 at least beyond the surface of the steel plate 2 and galling when the screw is started to be fastened with a screw can be prevented.  Even if the bolt 3 is inclined to the nut 1 and is inserted into the nut 1, inclination is corrected by the hole 21 and the recessed part 12. Therefore, assembling workability can be improved, even when the steel plate 2 is thin.

Moreover, when the temperature change Ts, the change Is in the current scanning range attended with the temperature change, and the current scanning width Iw satisfy equation III, the output light intensity change is less and the gap of the scanning frequencies is small. Thus, broad range optical frequency scanning is attained by scanning the temperature and the current and the scanning of the current is repeated by changing the temperature at a prescribed range. Thus, the optical frequency is scanned in a short time.

IPC: B07B1/55
Filed: 1992-07-09
Abstract: PURPOSE:To provide a cleaning device for standard industrial sieves which does not damage the mesh of a sieve and demonstrates a high removal effect upon the plugged mesh in an extremely short cleaning time. CONSTITUTION:A cylindrical sieve cleaning cylinder 2 is installed on a sink 1. This cylinder 2 should preferably be installed at an oblique angle with the sink 1. Further, a cylindrical sieve receptacle 3 on which a sieve 4 is deposited, is mounted on the inner wall of the sieve cleaning cylinder 2, and the sieve 4 to be cleaned is deposited on the sieve receptacle 3. A high pressure water is ejected to the mesh surface of the sieve 4 using a high pressure water generation device. If the high pressure water is ejected at an angle of lower than 90 deg. to the sieve surface which is offset from the center of the mesh surface, the sieve 4 is rotated on the sieve receptacle at a high speed. Consequently, it is possible to clean the mesh extremely uniformly. In addition, even the persistently plugged mesh can be cleaned completely in an extremely short time. The mesh of the sieve is no longer damaged by adjusting the water pressure.
