Abstract: Inside a main chamber there are provided: first partition walls partitioning a deposition chamber having a deposition unit; and second partition walls disposed in continuation to the first partition walls so as to cover outer cylinder parts of a can-roller while leaving a first gap that curves at a curvature coinciding with an outer peripheral surface of the can-roller. The deposition chamber and an adjacent chamber are in communication with each other with the first gap such that a conductance between the deposition chamber and the adjacent chamber is determined by the second partition walls. At least one of the second partition walls is arranged to be rotatable, with a rotary shaft of the can-roller, between a shielding position which shields such a part of the can-roller as is lying opposite to the deposition unit, and a withdrawn position which is circumferentially away from the deposition unit.

Abstract: A vapor deposition unit of this invention is provided with: a container box for containing therein a vapor deposition material; and a heating means for heating the vapor deposition material inside the container box, and which has formed in one plane of the container box a discharge opening for discharging a sublimated or evaporated vapor deposition material as a result of heating. The vapor deposition unit is further provided, inside a storing chamber, with a moving means for moving the vapor deposition unit. Provided that a direction looking toward the opening in the storing chamber is defined as an upper side, the moving means moves the vapor deposition unit disposed in the storing chamber in an up-and-down direction in a posture coinciding with a phase of the discharge opening.

Abstract: A roll-to-roll deposition apparatus includes a vacuum chamber, a film travel mechanism, a lithium source, and a first roller. The vacuum chamber is capable of maintaining a reduced-pressure state. The film travel mechanism is capable of causing a film to travel inside the vacuum chamber. The lithium source is capable of evaporating lithium inside the vacuum chamber. The first roller is disposed between a deposition surface of the film and the lithium source. The first roller has a transfer pattern that receives the lithium evaporated from the lithium source. The first roller transfers a pattern of a lithium layer corresponding to the transfer pattern to the deposition surface while rotating.

The first roller transfers a pattern of a lithium layer corresponding to the transfer pattern to the deposition surface while being rotated.

Abstract: A concentric double axis actuator has a two-stage cross roller bearing, and a preceding-stage actuator and a subsequent-stage actuator which are linked in tandem. The front end of a subsequent stage rotary output shaft of the subsequent actuator, said subsequent stage rotary output shaft passing through a hollow section of the preceding-stage actuator and projecting forward, is linked and fixed to an inner ring of the two-stage cross roller bearing, and the inner ring functions as a subsequent-stage rotary output member. The output rotary side of the preceding-stage actuator is linked to an middle ring of the two-stage cross roller bearing, which functions as a preceding-stage rotary output member. The rotary output element of each stage is supported by the two-stage cross roller bearing, and surface oscillations of the rotary output member of each stage can be minimized, and the moment stiffness of the members can be increased.

Abstract: A unit type wave gear device (1) has a unit housing (2), one end of which is defined by a two-stage cross roller bearing (7). The two-stage cross roller bearing (7) has: an inner cross roller bearing formed by an inner ring (13), an intermediate ring (12), and inner rollers (17) inserted into an inner track (16); and has an outer cross roller bearing formed by an outer ring (11), the intermediate ring (12), and outer rollers (15) inserted into an outer track (14). A flexible externally-toothed gear (22) affixed to the intermediate ring (12) is rotatably supported by the unit housing (2) via the outer cross roller bearing. An input shaft (4) affixed to the inner ring (13) and a wave generator (23) affixed to the input shaft (4) are rotatably supported by the intermediate ring (12) via the inner cross roller bearing. A unit type wave gear device can be realized in which the number of components are reduced and a large moment load is applied.

Abstract: A ball screw/nut type linear actuator (1) where a ball nut (32) moves in forward-backward directions by rotation of a ball screw shaft (31) connected to a motor (22), wherein the ball screw shaft (31) is connected and fixed, in a small diameter hollow section (22c) of the motor shaft (22), to the motor shaft so that a part of the locus of the movement of the ball nut (32) also enters into a large diameter hollow section (22a) of the motor shaft (22). The construction eliminates the need of a coupling for connecting the motor shaft (22) and the ball screw shaft (31) and enables the ball screw shaft (31) to be supported together with the motor shaft (22) by bearings (27, 28) of the motor. As a result, a support bearing for supporting the ball screw shaft can be eliminated. Thus, a short and light linear actuator is realized.

Abstract: A motor (2) of a linear motion device (1) has a hollow motor shaft (21). A ball screw shaft (41) is inserted in a hollow section (25) of the hollow motor shaft (21), and a first male screw section (43), formed on the outer periphery of the ball screw shaft, is screwed into a female screw section (26), formed in the inner periphery of the hollow section, and fixed in position. A nut (46) is crewed on a second male screw section (45) formed on a shaft end section (44) of the ball screw shaft (41) that projects from the rear end of the hollow motor shaft, and the nut (46) is tightened at predetermined torque to a rear end face of the hollow motor shaft. Tensile force occurring between the first male screw section (43) and second male screw section (45) of the ball screw shaft (41) prevents loosening of the screwed section between the hollow motor shaft (21) and the ball screw shaft (41), and, as a result, the ball screw shaft (41) is kept firmly fixed to the hollow motor shaft (21) without having play.

Abstract: A flat, hollow brushless servomotor (1) has a motor housing (2), housing through holes (22a, 23a) formed in a center of both end plate portions (22, 23), a rotor shaft (41) of which a portion of both ends is exposed from the through holes, a tool-mounting hole (43) that extends through a center thereof, and workpiece insertion recesses (24, 25) formed in an external surface of both end plate portions (22, 23) of the motor housing (2) by reducing the thickness thereof. A workpiece with a shape that has facing portions facing each other across a narrow space can be introduced from an outside to a center of the motor (1) along the workpiece insertion recesses, and the facing portions of the workpiece can be machined by a tool mounted in the center of the motor.

Abstract: A bearing mechanism comprises a shaft rotatably supported by a bearing accommodated in a cylindrical bearing accommodating portion. The shaft is applied with varying load in response to a slidable movement of a pair of pistons so as to be displaced in a direction. The bearing is displaced corresponding to the displacement of the shaft being applied with the varying load. The bearing mechanism further comprises a biasing means. The biasing means biases the bearing to be always in contact with at least a portion of an inner peripheral surface of the cylindrical bearing accommodating portion in the other direction different from the direction in which the bearing is displaced in accordance with the varying load.
