The invention is a robot teaching pendant containing a display device with graphic display capabilities. Display data is displayed on the graphic display and includes the movement of a robot and taught points. This display data is generated by a display data generation unit based on robot programs stored in data storage unit by buffering the data from a robot controller. This display data may also include representative images of the robot tool along with its coordinates in a tool coordinate system and the taught points in a user or world coordinate system. Thus, the action of the robot can be visually recognized with ease, and the robot can be taught easily and accurately.

A robot control method capable of eliminating any influence of motion in a preceding path section to assure an accurate path movement with respect to a portion of a path section toward an end point. In a motion statement, a path-assurance section is previously designated in terms of length, time or path-assurance ratio for a moving path �2!.fwdarw.�3!. A path motion plan EFGH for the moving path �2!.fwdarw.�3! is created so that a path section represented by DHGK is the path-assurance section designated in the motion statement, assuming that D represents a terminal point of the motion along the moving path �1!.fwdarw.�2!. Consequently, an influence of motion of the moving path �1!.fwdarw.�2! is not exerted on the motion after a point in time represented by D or K, to assure a movement on the path �2!.fwdarw.�3! in the path-assurance section.

First, an operator sequentially teaches the start point A, the end point F and junction points B, C, D, E on the welding path by moving the torch head by jog feed without paying attention to the torch orientation. Next, a reference plane to define the orientation of the torch is specified, and an inclination angle and a forward angle representing the torch orientation be inputted into a robot controller. On the basis of these inputted angle data and the taught data, a basic welding orientation is automatically calculated. Further auxiliary points are set around the junction points B through E each forming corner parts connecting straight lines; tool vectors which may give a smooth torch orientation change through the corner parts are automatically calculated for the auxiliary points and the junction points; and on the basis of the results, a welding program is produced. Among elements which determine the torch orientation, an element relating to the rotation around the torch axis reflects the state at the time of teaching of points A to E.

An electronic device intended for use as a tag to be attached to identify contents of the container to which it is attached. In particular, the present invention relates to an electronic tag which has a facility for storing delivery information and is equipped with a responding means for transmitting the delivery information stored therein in response to a query signal received from an interrogating apparatus. Codes, including items such as the names and addresses of the destination and the sender, and a sorting code are written into predetermined blanks of a delivery label, and into a memory. The memory responds to a query by transmitting the sorting information to allow automated sorting. The tag may be initiated only when torn, to extend battery shelf life.

The primary object of the invention is to realize a mobile object identification system of simple construction and low cost, in which the responding unit attached to a mobile object writes data only once when it receives write signals repeatedly in communication with antenna units. When a tag unit (responding unit) receives a write signal from a writing antenna unit, it writes data to the data memory when a completion flag is cleared. When the data is first written, a control circuit sets the completion flag. Then, if the tag unit receives additional write signals in the communication area of the same writing antenna unit, the control circuit invalidates the data write command on the ground that the completion flag is set, thereby preventing duplicate data writing.

An automatic nominal data setting method in a visual sensor system is capable of accurately and rapidly setting nominal data with ease, and a correction data deriving method is executable on the basis of the automatically set nominal data. If operation of the visual sensor system in a nominal mode is determined (S200) upon start of execution of an orientation portion of a user program by the visual sensor system mounted on an industrial robot, a message for interrogating whether or not nominal data setting should be executed is displayed (S201). When an operator inputs a nominal data setting command (S202), the workpiece position/posture data in the sensor coordinate system at that time, determined based on gray-scale image data, is converted into workpiece position/posture data in the robot coordinate system to be stored as nominal data (S203). During a robot operation, the visual sensor system calculates correction data for correction of the operating position/posture of the robot on the basis of workpiece position/posture data created similarly and the nominal data, and supplies same to the robot.

A rack-and-pinion type steering gear for automotive vehicles including a columnar rack guide made of resin having a small coefficient of friction. An outer diameter of the rack guide in the direction perpendicular to the direction of movement of a rack bar is greater than an inner diameter of a rack guide hole for insertion of the rack guide in such a manner that the transverse cross-section of the rack guide is elliptical. With this arrangement, vibration of the rack guide in the rack guide hole due to an external force dynamically acting on the rack bar, thereby preventing generation of noise from the rack guide hole.

A power-assisted steering system includes a changeover valve unit comprising an input shaft to be rotated by the driver's steering effort applied thereto, an output shaft operatively connected to a hydraulic power cylinder associated with the steering system, a valve assembly for controlling the supply of fluid under pressure from a hydraulic pump to the power cylinder in response to relative rotation between the input and output shafts; and a hydraulic reaction mechanism for applying a reaction force to the input shaft in accordance with a hydraulic reaction pressure applied thereto. The reaction mechanism includes a reaction fluid chamber to be constantly applied with a predetermined small quantity of fluid under pressure and to be applied with a hydraulic pressure caused by relative rotation between the input and output shafts through a throttle. The system is arranged to increase the hydraulic pressure in the reaction fluid chamber in accordance with an increase of travel speed of the vehicle.

A control apparatus for a gas turbine engine comprises an accelerating condition detecting mechanism and an operating speed control mechanism. The accelerating condition detecting mechanism detects the degree of acceleration in the engine. The operating speed control mechanism controls, depending upon the degree of the acceleration, the speed for opening variable nozzles installed in the inlet portion of a power turbine of the engine, and/or variable inlet guide vanes installed in the inlet portion of a compressor of the engine.
