摘要： PURPOSE:To improve vacuum-clamping and mounting accuracies of a work without undesired variation in rotational angle of a turning shaft by providing a brake for applying a predetermined frictional brake force to the shaft. CONSTITUTION:A work mounting apparatus comprises a work head provided on the outer periphery of a head drum 28 to be rotatably driven with respect to a work base 2 and turned around a first sleeve shaft (turning shaft) 154 with its attitude unchanged, and a brake 202 for applying a predetermined frictional brake force to the shaft 154. When the brake force is always applied to the shaft 154 by the brake 202 to be transmitted, the shaft 154 is rotated against a frictional brake force. Accordingly, its rotational angle control can be accurately executed.

摘要： PURPOSE:To stabilize a work head turning speed and to accurately execute its variable control by providing a link arm fixed at the center to a turning shaft and mounted at one end with a work head, and a balance weight mounted at the other end side of the arm and opposed to the head side. CONSTITUTION:A work head 70 is mounted on its turning shaft, i.e., a first sleeve shaft 154 through a link arm 110, and a balance weight 126 for the head 70 side mounted on the arm 110. When the head 70 is turned to pick up and mount works repeatedly upon rotation of a head drum 28, the weight 126 spaced radially of the turning shaft is also turned together with the head 70. Accordingly, the head 70 is stably and smoothly turned around the turning shaft.

摘要： PURPOSE:To obtain a repairing device inside a pipe which can perform repair and other works in a short time with secured safety and can be applied to even a pipe of a complicated shape, by providing a travelling truck, a suction mechanism, a track whose shape corresponds to the inside shape of a pipe, and a work device which moves on the track for working. CONSTITUTION:A suction pad 5 is installed downward on the under surface of the bottom of a travelling truck 2, and an arc-shaped track 6 is provided on the front side through a track inclining mechanism 7 and a track driving mechanism 8. The arc-shaped track 6 is equipped with a freely movable working head 9. Working devices, such as an overall supervising television camera 10, a paint supply device 11, a blasting device 12, and a communication control device 13, are provided on the traveling truck 2. This allows to perform repair and similar works in a short time with secured safety. Furthermore, repairing work can be applied to even a pipe of a complicated shape.

摘要： PURPOSE:To surely hold alignment, etc., of a laser beam by forming a light shielding part on the photodetecting surface of a photodetector on a machining table, moving a laser beam so as to cross a light shielding part end and signal- processing an output value of the photodetector and a positional signal of a beam scanner. CONSTITUTION:The laser beam L is led to a nozzle 1 and a work on the machining table 2 is irradiated and machined with the laser beam. The photodetector 3 is then arranged on the machining table 2. The light shielding part to intercept the laser beam L is formed on a part of the photodetecting surface of this photodetector. The laser beam L irradiates and moves so as to cross the end of the light shielding part. At this time, the output value of the photodetector 3 and the positional signal of the beam scanner are processed by a signal processing part 5 and laser beam L characteristics are detected. Consequently, the space distribution of power intensity of the laser beam in two directions to cross orthogonally and the beam diameter of the laser beam and the position of an optical axis can be easily detected.

摘要： PURPOSE:To simplify the teaching work of a robot by defining a working area in the range wherein the robot is movable independent of the joint coordinate of the robot and providing a means for judging whether a teaching point is in this working area or not. CONSTITUTION:Prior to teaching work, a working area 4 required for desired work is defined in the area wherein a robot is movable by a working area defining means 1. In the next step, whether points 5 which the robot is to be taught are in this working area or not is judged by a judging means 6, and the result 7 judged is output, and the points only in the working area 4 are taught to the robot. This leads to easy performance of teaching work.

摘要： PROBLEM TO BE SOLVED: To provide a double deck elevator device which allows easily and simply adjusting the interval between first and second elevator cars. SOLUTION: This double deck elevator device has a first elevator car 23a vertically disposed within an outer frame and a second elevator car 23b. The outer frame is raised and lowered via a hanging rope 16. A transmission member 19 having a first threaded shaft 19a which engages a car frame 22a supporting the first elevator car 23a and having a second threaded shaft 19b which engages a car frame 22b supporting the second elevator car 23b is freely rotationally provided in the outer frame. The first threaded shaft 19a and the second threaded shaft 19b are threaded in the opposite directions and driven by a driving motor 17. Rotation of the transmission member 19 adjusts the interval between the elevator cars 23a, 23b.
