摘要:
A timing library test apparatus includes a difference calculator looks into a look-up table in a timing library, the look-up table having timing constraint values registered in association with combinations between reference transient times of a signal at a reference terminal and constraint transient times of a signal at a constraint terminal, and groups neighboring two timing constraint values in the look-up table as one pair, respectively, to calculate differences between neighboring two timing constraint values of pairs, a determination part determines whether the differences calculated by the difference calculator has a characteristic feature of increase inclination or decrease inclination, and a decision part decides that the timing library has a singular point when the determination part determines that the differences doesn't have the characteristic feature, and to decide that the timing library doesn't have the singular point when the determination part determines that the differences has the characteristic feature.

A robot position teaching system and method including a robot controller to control a robot, a visual sensor to measure a three-dimensional position, an image processing device to measure a position by processing and analyzing an image recognized by the visual sensor, and a position teaching unit provided with a grasping portion having a size which can be grasped by a hand of an operator, and an index which can visually be recognized by the visual sensor, and is disposed at a distal end of a rod-type body extending from the grasping portion. The operator turns on a moving switch of the position teaching unit such that the robot controller moves the robot toward a position of the index recognized by a camera. When an approach teaching switch of the position teaching unit is turned on after movement of the robot is stopped, data of a current position of the index recognized by the camera is stored as teaching position data. On the other hand, by turning on an arrival teaching switch, a current position of the robot is stored as the teaching position data.

First standard cells with no contact pattern and second standard cells having first contact patterns are placed on an area where a cell array is to be formed. Second contact patterns are additionally placed between the first standard cells. The second contact patterns are placed in an area that lacks a power supply capability.

While jog feeding, if the robot can be moved safely without interference or collision with others, the data on jog feeding path is accumulated in an external memory device. And a safe region in which the robot can move without interference or collision can make from some accumulated paths in the robot axial space and stored. When start point and end point for the desired path are specified, one path, which links the start point and the end point and is composed of such safe regions, is found. Then the robot positions are taught as positions corresponding to the path.

Even where an I/O cell requiring good characteristics is alloted to an I/O slot corresponding to the uppermost standard pattern wiring, a pad can be connected to the I/O slot by forming rewiring in the chip outermost peripheral area.

A weigher-conveyor has a conveyor which is for transporting an object and is supported by a weighing device such that the weight of the object on the conveyor can be measured while it is being transported. A detector is disposed near the downstream end of the conveyor and, when the presence of an object on the conveyor is detected, a control unit determines whether weight signals from the weigher are already stable. If they are stable, the conveyor continues to be driven and a weight value indicated by the stabilized weight signals is outputted. If they are still unstable, the conveyor is stopped until the weight signals stabilize. A weight value indicated by the stabilized weight signals is outputted in this situation.

In the weighing apparatus, a plurality of weighing sections are connected to a main unit having a display section, and weight data from one of the weighing sections are indicated by the display section. Each weighing section has an instability detection section for detecting the instability of a weight signal. The main unit has a section by which the weight data from the weighing section whose weight signal is instable are selected on the basis of a signal from the instability detection section.

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.
