摘要:
In a spot welding gun which is made up of a gun main body which is operated for equalization by a driving source, a stationary electrode tip which is immovable relative to the gun main body, and a movable electrode tip which is connected to a pressing source, both electrode tips are pressed to a workpiece with an even force, to thereby perform a high quality spot welding. The driving source is controlled such that the electrode force of the stationary electrode tip, by the driving source, to the workpiece becomes substantially zero. In this manner, there occurs no difference in the electrode forces by both the electrode tips to the workpiece.
摘要:
When a workpiece which is made up by laminating a plurality of plates of different thicknesses is welded by using a spot welding gun having a pair of electrode tips, the electrode force to the workpiece by one of the electrode tips, which is positioned on the side of a thinner plate, is made larger that the electrode force to the workpiece by the other of the electrode tips. The contact pressure on the side of the thinner plate becomes larger with the result that the contact resistance decreases. Therefore, the nugget on the side of the thinner plate becomes smaller than the nugget on the side of the thicker plate.
摘要:
A welding robot has a gun main body, a stationary electrode tip which is immovable relative to the gun main body, and a movable electrode tip which is mounted on the gun main body and is opened and closed by a pressing source. The gun main body is movable by a driving source in a direction in which both the electrode tips lie opposite to each other. In teaching the welding robot by the movement thereof to each weld spot position of a workpiece, the movable electrode tip is moved in a closing direction relative to the gun main body by the pressing source in a state in which the gun main body is kept stationary at a predetermined position relative to the gun support bracket. The stationary electrode tip is moved in the closing direction by a relative movement of the gun main body relative to the movable electrode tip after the movable electrode tip has come into contact with the workpiece. A position at which the stationary electrode tip contacted the workpiece is detected. This position is stored as teaching data.

There is disclosed a high-pressure tank capable of appropriately discharging high-pressure gas. The high-pressure tank is mounted on a mobile body, stores the high-pressure gas, and includes a plurality of gas discharge means for discharging the high-pressure gas from the high-pressure tank. The gas discharge means are disposed at opposite sides of the high-pressure tank in a longitudinal direction. The gas discharge means can each have a path through which the inside of the high-pressure tank communicates with the outside thereof, and a manual valve including a manual operating section for opening and closing the path by a manual operation.

There is disclosed a valve assembly for a gas container capable of appropriately discharging a gas from the gas container, even if a valve of a discharge passage has a failure or the like. The valve assembly for the gas container disposed at the gas container has, as passages which allow the inside of the gas container to communicate with the outside, a filling passage which fills the gas container with the gas and a discharge passage which discharges the gas. Furthermore, the valve assembly has a filling-side valve disposed at the filling passage and configured to close this passage, a discharge-side valve disposed at the discharge passage and configured to close this passage, a communication path which connects a downstream side of the discharge-side valve to a downstream side of the filling-side valve, and a shut-off valve disposed at the communication path. When the discharge-side valve does not open due to the failure or the like, the shut-off valve is opened to allow the gas to flow through the filling passage, the communication path and the discharge passage in this order.

Provided is an information processing system that communicates with a storage apparatus through a plurality of paths Pi (i=1 to n, where n is a total number of the paths), and that issues an I/O to the storage apparatus through one of the paths Pi. The information processing system sets weights Wi for the respective paths Pi; obtains an I/O issue interval di of each of the paths Pi by dividing a sum total ΣWi of the weights Wi by the weight Wi set for the path Pi; obtains I/O issue timings ti(m)of each of the paths Pi by using the following equation: ti(m)=di/C+m·di (m=0, 1, 2, . . . ) (where C is a constant); and issues the I/Os to the paths Pi in an order corresponding to the an order of the I/O issue timings ti(m) chronologically arranged.
