Abstract:
A device for feeding electronic parts, capable of surely feeding electronic parts in a stable posture to an electronic part mounting machine, stabilizing winding of a peeled-off top tape, and enhancing a mounting speed. When a reel (42) winds a top tape (4), a shutter (34) retreats and a slit (51) formed integral with the shutter (34) also retreats. Revolution of the reel (42) in a tape winding direction is effected by a restoring force of a restoring spring (39). When winding movement of the reel (42) is terminated and the shutter (34) retreats, electronic parts (1) are taken out at an electronic part taking-out position. A stationary roller (31) is provided between the slit (51) and the reel (42), and further a moving roller (32) is provided for keeping a length of the top tape (4) between the slit (51) and the stationary roller (31) substantially constant.
Abstract:
A process for producing an acetal copolymer by copolymerizing trioxane with a cyclic ether copolymerizable therewith, wherein the cyclic ether is a mixture of a fresh cyclic ether wherein the content of a peroxide derived therefrom is at most 15 wt. ppm in terms of hydrogen peroxide and at least one sterically hindered phenol added in a quantity of 10-500 wt. ppm based on the ether. This process enables a highly heat-stable acetal copolymer to be produced in a stabilized manner, and also enables deactivation of the catalyst and stabilization of the unstable polymer ends to be effected in a stabilized manner after the copolymerization.

Abstract:
A calibration system for an industrial robot capable of carrying out calibration in a short time. A calibration device (3) having a six-axis degree-of-freedom-of-motion and also having displacement detecting devices provided for respective degrees of freedom is mounted on a reference surface (1p) provided on a robot (1) itself or a reference surface where a positional relationship with the robot is already known, and the leading end portion of the calibration device (3) is mechanically coupled to the leading end portion of the wrist of the robot, whereby the position data/attitude data obtained from the displacement detecting devices of the calibration device (3) are calculated back to the position data/attitude data of the robot for calibration of the robot.
Abstract:
A Fas ligand solubilization inhibitor which comprises as the active ingredient a compound represented by general formula (I) having a matrix metalloprotease inhibitory activity or a pharmaceutically acceptable salt thereof. This drug is useful in the prevention or treatment of diseases caused by solubilized Fas ligands such as hepatitis, GVHD, AIDS and autoimmune diseases.
Abstract:
A method of, and an apparatus for, mounting electronic components in which the steps of an intermittent feed operation can be varied in accordance with the kind of the electronic components to increase operation speed. When the electronic components are fed intermittently, the steps of feed are varied in accordance with the kind of the electronic components that are supplied from a parts feeder and held on an attraction nozzle for the mounting on a substrate.
Abstract:
The work-space envelope of a conventional articulate multiple-shaft robot is limited to within U180° with respect to all shafts due to the construction of the robot. The expansion of the work-space envelope of a robot has come to be demanded recenlty, and the construction of and a control method for a robot has been improved accordingly, so that this envelope has been expanded to up to U360°. However, it is difficult in some cases to apply such a control method to a robot having a shaft which is turned not less than U360°, and the robot cannot be operated in some cases. Therefore, according to the present invention, in order that a signal representative of a position to which a shaft has been turned is indicative of an angle within the range of U360° with respect to a reference position of the same shaft, a signal representative of the number of revolutions which is obtained by multiplying the number of revolutions of the mentioned shaft by an integer is added to or subtracted from the above actual position signal in accordance with a plus or minus sign thereof, and a signal representative of the result of this addition or subtraction is used as a signal representative of a position of rotation of the shaft at the time of starting of a posture control operation. This corrected link angle becomes less than U360°. Therefore, if this control method is employed, a smooth interpolation operation can be carried out. Accordingly, the workspace envelope of an articulate multiple-shaft robot can be expanded.
Abstract:
An electronic part mounting device comprises a plurality of vacuum-chucking nozzles (1) mounted to the periphery of an intermittent rotating table vertically movable, a cylindrical cam (105) having in the entire circumference thereof cam grooves (106, 107a, 107b) for vertically moving the nozzles (1), a first roller (5) mounted to a first slide section (4a) having the nozzles (1), and traveling in the cam grooves (106, 107a, 107b) to move the nozzles (1) vertically, a second roller (6) mounted to a second slide section (4b) mounted to the suction nozzles (1), and traveling in the cam grooves (106, 107a, 107b) to vertically move the nozzles (1) together with the first roller (5), and a spring (9) for biasing the first roller (5) and the second roller (6) against both side faces of the cam grooves (106, 107a, 107b).
Abstract:
Egg conveyor for collecting and conveying eggs, transferred from cages, without breaking them. In the present invention, an egg collecting rack is suspended from an endless belt in such a manner as to be rocking freely and a receiving portion of the egg collecting rack receives the eggs on a support portion while a discharge portion discharge them. To this end, each of the receiving portion, support portion and discharge portion of the egg collecting rack has a comb-like shape. Since the egg collecting rack can rock freely, the egg collecting rack can transfer the eggs horizontally so that the eggs are not broken and cracks do not occur, either. A scraper member is disposed in order to easily send the eggs to an egg collecting table at the discharge position of the egg collecting rack. Furthermore, a stopper mechanism operates so as to stop the operation of the endless belt if any foreign matters exist at the discharged position and the egg cannot be discharged from the egg collecting rack.
