  • Patent number: 11947263
    Abstract: A laser chamber of a discharge-excitation-type gas laser apparatus may include a container which contains laser gas therein; a pair of discharge electrodes arranged in the container; a cross flow fan configured to supply the laser gas to a discharge space between the discharge electrodes, the cross flow fan including a rotation shaft with which the cross flow fan rotates in a predetermined rotation direction and a plurality of blades, each longitudinal direction of which is parallel to an axial direction of the rotation shaft; and a stabilizer arranged outside a rotation trajectory of the cross flow fan, and arranged such that a difference between a maximum position and a minimum position of an end portion in the rotation direction on a side opposite to the rotation direction is larger than 0 and is smaller than an interval of two blades adjacent to each other among the plurality of blades.

  • Patent number: 4538950
    Abstract: A system is disclosed for automatically transporting works between an automated warehouse and a machine tool, and for maintaining the works in a precise position with respect to the machine tool. The system includes an automated warehouse, a pallet for precisely holding works, a truck for carrying the pallet, the truck moving along rails between the warehouse and a work exchanging apparatus adjacent to a machine tool table, and a device for positioning the pallet on the machine tool table precisely with respect to the machine tool. The work exchanging apparatus operates to transfer a pallet which holds unmachined works from the truck to the machine tool table and to transfer a pallet holding machined works from the machine tool table to the truck. The pallet, machine tool table, truck and work exchanging apparatus include means to position the pallet so that after a work is initially positioned on the pallet, the work will be precisely positioned with respect to the machine tool.

  • Patent number: 4534692
    Abstract: Herein disclosed is a materials flow system for an automatic warehouse, which is intended to eliminate any loss in the standby time of a worker during a machining process and to unman the machining process itself. The materials flow system includes a first stacker crane which is interposed between two automatic warehouses arranged in parallel for transferring materials to either of the warehouses. Further inclusive is a second stacker crane which is disposed in front of either of the automatic warehouses and which are equipped with two sets of slide forks for simultaneously transferring two materials between the warehouses.
