Title: Belt slip-off preventing mechanism for physical distribution conveying system
Inventor: NAKAMURA HISATO
IPC: B65G39/16
Filed: 1987-09-30
Abstract: PURPOSE:To prevent a belt from slipping off, in a conveying system for wafers or the like, by using grooved rollers as driven rollers, and by enabling meandering correction rollers to move orthogonal to the belt running direction in a range wider than the groove width of the driven rollers. CONSTITUTION:When a belt 3 initiates meandering, the belt 3 is moved to one end of a groove in a driven roller 12. Further, the meandering is increased, the belt 3 becomes impossible to move on the driven roller 12, and accordingly, a part of the belt 3 on a meandering correction roller 14 is alone further moved being biased. With this arrangement, the belt 3 bows. Further, when the meandering force is decreased after it exceeding its maximum value, the meandering correction roller 14 is swung by the force of the bowed belt 3, and is deflected to the right in the drawing, to eliminate the bow of the belt 3 so that the belt 3 is returned to and stabilized in its rectilinear condition. With this arrangement, there is no possibility of the belt slipping out of the groove, thereby it is possible to prevent the belt from slipping off.

IPC: G11B5/53
Filed: 1983-12-28
Abstract: PURPOSE:To reduce oscillation and noise and to make a device small-sized by supporting a journal load with two fluid dynamic pressure bearings and supporting a thrust load with a point contact thrust bearing. CONSTITUTION:The lower end face of a revolving shaft 1 is brought into contact with a pole 22 of a thrust bearing 21 provided in the center part of a stator structure 13, and the thrust load which acts in the axial direction of the revolving shaft 1 by the weight of a rotary drum 5 is supported. Fluid dynamic pressure bearings 20 and 20' consist of a bearing structure 18 fitted into a bearing housing 12 and many narrow and shallow grooves 19 and 19' which are provided in a part of the revolving shaft 1 to face the bearing structure 18. When the revolving shaft 1 is rotated, a fluid is drawn into the space between the bearing structure 18 and the revolving shaft 1 along grooves 19 and 19', and a fluid dynamic pressure is generated there to give a centripetal force to the revolving shaft 1, and the revolving shaft 1 is supported without contacting. The journal load acting upon the revolving shaft 1 is supported by this centripetal force. Air, grease, or the like is desirable as the fluid. Thus, the solid contacting part of the bearing part is reduced, and oscillation and noise for rotation are reduced considerably.

Title: Air passage opening and closing device
Inventor: KATO HIDEAKI
IPC: B60H1/00
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To slide sliding doors used in air passage opening and closing devices smoothly in a low-temperature environment. SOLUTION: A sliding door 30 slidable across an air passage opening has guide pins 30a at the ends of opposite sides in a direction perpendicular to the sliding direction. A case 12a holds on the internal wall surface guide grooves 12b extending parallel in the sliding direction and having a U-shaped form with a down slanting lower flange surface. A fit between the guide pins 30a and the guide grooves 12b holds the door 30 slidable in the case 12a. Even on an intrusion of water or the like into the guide grooves 12b, the down slanting lower flange surfaces of the guide grooves 12b help the water drop out of the guide grooves 12b, and point contact between the guide pins 30a and the guide grooves 12b keeps the water less liable to stay about the contact areas, which thus prevents malfunctions of the sliding door 30 by icing in a low-temperature environment.
