摘要： A wrist-joint mechanism for industrial robots is specified. In a power transmission train for the wrist-joint mechanism of a robot arm, a reduction gearing is arranged close to the front end of a wrist joint such that the torque from actuating units, serving as drive units and arranged on the robot arm, is transmitted to the reduction gearing close to the front end of the wrist joint in a quantity which is substantially equal to that of the torque of the output shaft of the actuating units. Bevel gears, which form the power transmission train, can be arranged outside the outer housing, so that an adjustment or the like of the individual parts of the wrist-joint mechanism can be carried out in a simple way.

摘要： PROBLEM TO BE SOLVED: To provide a data gathering system of a low cost capable of obtaining required sufficiently high reliability even when a general purpose personal computer is used without the need of the OS and hardware of special specifications. SOLUTION: Plural data processors 1A and 1B are connected by a communication channel 3 and data inputted from terminals 4A-4n to one of them are inputted to the other data processor as well through a data transmission line 5 and stored there as well. The data to be gathered are respectively preserved in storage devices provided inside the, at least, two data processors 1A and 1B. Thus, even when abnormality is generated in one of the data processors 1A and 1B and it is stopped, as long as the remaining data processor is normally being operated, since the omission of the data to be gathered does not occur, as this entire data gathering system, a continuous operation is obtained and the required reliability is maintained.

摘要： PURPOSE:To miniaturize the revolving mechanism of an industrial robot by bonding an about cylindrical rotating output member to the output shaft of a speed reducing mechanism whose input shaft and output shaft become co-axial, transmitting a revolution driving force to the inside of the cover of a mobile base and giving the driving force for the input shaft by the inside of this rotation output member. CONSTITUTION:A motor 2 is controlled by rotating via a cable 6, the driving force of this motor 2 is decelerated at specific ratio by a speed reducing mechanism 3 and a mobile member (revolving base of a robot) 4 is turned around a center shaft 5 via a deceleration output part 32. In this case, the driving input shaft 93 of the deceleration mechanism 3 is arranged at the inner part of revolution driving force transmission members 8, 10. So that, the power of the motor 2 is input from the upper part of the deceleration mechanism 3 and returned to the upper part again after being decelerated and as a result, the dimension in the axial direction of the mechanism turning the rotating member 4, i.e., the height thereof is lowered and the revolving mechanism is made compact.

摘要： PURPOSE:To reduce the occurrence of thermal stress in a high temperature combustion gas flow, in the titled structure in which a metal blade core is arranged in a ceramic stationary blade comprising a blade portion and side wall, by forming a notch in the part of the side wall. CONSTITUTION:A blade portion 3 made of ceramic and side wall 1 made of ceramic which is insertedly fitted into the blade portion 3 are supported by a metal blade core 6 passing through the blade portion 3 via a supporting plate 7. Between the ceramic and metal, a heat shielding layer 8 serving as a deformation buffering layer is arranged. With such a constitution, a notch 9 is formed in the part of the side wall 1 for reducing thermal stress. Therefore, a restricted deformation caused by a temperature difference is released and the ceramic member in a high temperature combustion gas flow is prevented from the occurrence of the thermal stress. Therefore, it is possible to obtain the ceramic blade with high reliability.

摘要： PURPOSE:To obtain sufficiently uniform weaving by the small number of teaching point inputs by inputting weaving data only at a point where a weaving operation pattern is changed. CONSTITUTION:At the teaching of a point P1, weaving auxiliary points W11, W21 are inputted, so that the direction and amplitude of weaving at the point P1 are set up and the 1st operation pattern in an area 1 from the point P1 to a point P3 is regulated. Therefore, inputs such as auxiliary points W12, W22 are unnecessary at the points P2, P3. In an area 2 from the point P3 to a point P5, the weaving pattern is different and the 2nd operation pattern is adopted, so that auxiliary points W13, W23 are teached at the point P3 to specify the weaving operation pattern in the area 2. Once the auxiliary points have been teached, the weaving of the 2nd operation pattern is executed in the area 2 until the succeeding auxiliary points are newly teached.

摘要： PURPOSE:To enable a ceramic shaft to be connected with a metallic shaft, by plastically fluidizing a metallic ring, inserted between the peripheral surface of a ceramic shaft part and the internal peripheral surface of a metallic shaft part, to be deformed by the metal flow method. CONSTITUTION:A ceramic shaft 11 is fitted to the shaft hole of a metallic shaft 12, and a metallic ring 13, consisting of a material having a thermal expansion coefficient equal to a ceramic, is inserted into a part between the peripheral surface of said ceramic shaft 11 and the internal peripheral surface of the shaft hole of the metallic shaft 12. Next the ceramic shaft 11 is connected with the metallic shaft 12 by plastically fluidizing the metallic ring 13 to be deformed by the metal flow method. While the metallic shaft 12, providing in the internal peripheral surface of its shaft hole a groove 14 and plastically fluidizing a metal to be deformed and allowed to flow into said groove 14, can prevent a decrease of surface pressure between the metallic shaft 12 and the metallic ring 13. This surface pressure can be controlled by changing a thickness of the metallic ring 13.
