Abstract: A rotary actuator has: one motor, two strain wave reduction gears disposed symmetrically on both sides of the motor, and one output shaft. The output rotation of the motor is reduced in speed at the same reduction ratio by the two strain wave reduction gears and is outputted from the output shaft to a load side. The first and second externally toothed gears of the first and second strain wave reduction gears are flexed into ellipsoidal shapes with 90 degrees shifted in phase, and are meshed with first and second internally toothed gears. The angle transmission errors of the first and second strain wave reduction gears transmitted to the output shaft are reduced by cancelling each other out in the output shaft. Reduced-speed output rotation that has the reduced angle transmission errors is outputted to the load side from the output shaft.

Abstract: A rotation actuator is equipped with a motor and a reduction gear disposed adjacent to each other. Both shaft end portions of a rotating shaft, which passes through the center of the motor and reducer, are rotatably supported through first and second rolling bearings by first and second fixed discs that are mutually fastened and fixed. A rotation output plate is supported through a third rolling bearing in the outer peripheral surface of the second fixed disc. A sliding ring is mounted between the rotation output plate and the first fixed disc. The sliding ring functions as a thrust bearing for the rotation output plate and also functions as a sealing mechanism for preventing grease from flowing from the reducer gear to the outside. A flat rotation actuator can be achieved.

Abstract: The present invention is to ensure that when it has been judged that film-formation areas of a plurality of layers laminated on the same luminescent areas of organic EL devices involve a defect, it is possible to exactly find which layer of the multi-laminated layers is a defective layer. The film formation areas of layers to be laminated on luminescent area are formed in a manner such that overlap deviations e1-e3 are intentionally formed.

Abstract: A low-bed type seismic isolator for a display case, which includes: at least two lines of arcuate X-rails (3) fixed to a lower plate (1) on a foundation and having lower central portions and higher end portions; at least two lines of arcuate Y-rails (4) fixed to a lower surface of an upper plate (2) above the X-rails (3) and having higher central portions and lower end portions in a direction perpendicularly to the X-rails; connection blocks (5) having lower portions clamping the X-rails, upper portions clamping the Y-rails, and a disk spring provided at the central portions thereof; absorbers (8) disposed on the ends of the X-rails and Y-rails and recesses which fixedly accommodates support legs (7) fixed to the lower surface of the upper plate and protruded downwardly from a seismic isolation object.

Abstract: A seismic isolator includes a lower guide rail 4 having grooves on the side surfaces thereof and fitted to an upper surface of a lower plate 1, an upper guide rail 6 having grooves on the side surfaces thereof and fitted to a lower surface of an upper plate in a direction criss-crossing the lower guide rail 4, a block body 9 clamping at its lower part the lower guide rail 4 and clamping at its upper part the upper guide rail 6, a large number of rollers interposed between the lower guide rail 4 and the block body 9 and between the upper guide rail 6 and the block body 9, a large number of balls interposed between grooves of the side surfaces of the lower guide rail 4 and the block body 9 and between grooves of the side surfaces of the upper guide rail 6 and the block body 9 and a flexible member 22 fitted between the lower surface of the upper plate and the upper surface of the lower plate 1.

Abstract: A seismic isolation sliding bearing for a structure, is made up of a dish 1 having a conical concave surface having a predetermined inclination or a spherical concave surface in its central portion, and a bearing element 2 in which the bearing element includes a base 3 whose portion for contact with the concave surface of the dish 1 is formed by a low-friction material, and a holder 6 which holds the base 3 so as to press it against the concave surface of the dish 1. The seismic isolation sliding bearing of the present invention neither resonates to the vibration period of any earthquake nor causes a large oscillation during a normal small vibration, but has a restoring force because of its structure which enables the bearing element to readily return to its original position after an earthquake ceases.
