A system for controlling acceleration and deceleration of a horizontally articulated robot computes the distance from the center of rotation of the robot (A) having a plurality of arms (3, 5) angularly movable in horizontal planes to a reference position such as a wrist (51) at the distal end of the arms (3, 5), and establishes an acceleration for the movement of the distal end of the arms (3, 5). A servomotor for angularly moving the arms (3,5) can effectively be utilized and the arms (3, 5) can quickly and smoothly be moved.

A double hand for an industrial robot comprises a hand body, two sets of work clamping units and two sets of actuators to drive the work clamping units, respectively, for opening and closing motions. The hand body has a rear end attachable to the free end of the robot wrist of an industrial robot, a front end and opposite sides extending between the front end and the rear end. Each work clamping unit has a pair of gripping fingers and the pairs of gripping fingers of the two sets of work gripping units are supported pivotally at the roots thereof on the opposite sides of the hand body for turning motion. The paired gripping fingers are turned about the respective roots thereof in opposite directions by the associated actuator.

A film carrier tape for mounting electronic parts comprises an insulating film, a wiring pattern formed on a surface of the insulating film, and a solder resist layer formed by moving a squeegee using a screen mask of a prescribed pattern that is formed in such a manner that connecting terminal portions of the wiring pattern should be exposed. The edge of the solder resist layer is formed almost in parallel or almost at right angles to the moving direction of the squeegee used in the application of the solder resist. The solder resist layer can be formed by the use of a screen mask for solder resist coating in which the edge of the screen that is unmasked to apply the solder resist is formed almost in parallel or almost at right angles to the moving direction of the squeegee used in the application of the solder resist. According to the present invention, the fraction defective of the solder resist coating can be decreased.

An image of a reference object is captured using a camera and displayed. A measurement starting point is pointed by an image position pointing device. A corresponding view line is obtained using a position on the image and a position and a direction of the camera, a robot approaches to the reference object such that it does not deviate from a projecting direction to move to a position suitable for measurement. A light is projected on the reference object and measurement of an inclination of a face of the object in the vicinity of a measuring point is started. An image including a bright line image on the reference object is photographed and 3-dimensional positions of points sequentially measured along a working line. A movement path of a robot is created using these positions as teaching points for a working robot.

A deadman switch mechanism and a teaching operation panel equipped with the deadman switch mechanism, in which possibility of losing a safety function is low even if failure happens in a contact or other elements of a circuit. When an operator grips at least one of grip levers (GL1; GL2) with normal force, the grip levers turn around axes (AX4; AX5), shoulder portions (SD1; SD2) abut on slave levers (SL1; SL2) and turns the slave levers connected by a link (LK) around an axis (AX3) in the direction denoted by an arrow B, simultaneously, so that switches (SW1; SW2) are turned into an ON-state, simultaneously. Then, two circuits including those switches, respectively, output ON-signals independently and these signals are subjected to AND process, to allow the robot to operate. In an emergency, when an operator releases gripping of the grip levers (GL1; GL2), the slave levers (SL1; SL2) turn in the direction denoted by an arrow A, simultaneously, so that the switches (SW1; SW2) are brought into an OFF-state, simultaneously, and the robot stops immediately.
