摘要： PURPOSE:To suppress a vibration at the time of stopping a stepping motor thereby to accurately position the motor by repeating normal and reverse rotations predetermined times after a final pulse is delivered. CONSTITUTION:Rear pulse train data generating means 2 produced the final step pulse of pulses for driving a stepping motor, and then generates pulse train data to be delivered. Switching means 6a reads out, upon inputting final pulse discriminating means 6, rear pulse train data, and alternately outputs a switching signal for switching a pulse direction to normal or reverse to a stepping motor drive circuit 7 synchronously with the rear pulse train data. Thus, the vibration of the motor is attenuated during the inputting period of the pulse signal which varies in normal and reverse directions.

摘要： PURPOSE:To provide a laser beam processing machine with reduced astigmatism, which is caused by a curved surface mirror. CONSTITUTION:A beam enlarging means 120 and 122 enlarging the diameter of a laser beam, and a converging means 124 converging the laser beam, including plural curved surface mirrors, are provided. An object 100 to be worked is worked by irradiating the object 100 to be processed, which is supported on a supporting stand, while scanning the laser beam in two dimension or three dimension. And an incident angle e1 formed by the normal of the curved surface mirror and the optical axis of the laser beam is selected for each curved surface mirror so that the astigmatism of the laser beam after enlarged by the beam enlarging means 120 and 122 becomes the minimum.

摘要： PURPOSE:To obtain the deodorizing function, and also, to prevent the dimension variation of an object to be cut by providing a deodorizing device and a drying device, and controlling a temperature and the injection quantity of water vapor and hot air. CONSTITUTION:When an object to be cut after cutting is fed to a deodorizing device 20 by a conveyor, water vapor and hot air of a prescribed temperature are injected to its upper and lower faces. As a result, an odor component adhering to the upper and the lower faces of the object to be cut or a section of cutting is decomposed and deodorized. When a prescribed time elapses, the conveyor is driven, the object to be cut is fed to a drying device 21. In the drying device 21, moisture applied by water vapor in the deodorizing device 20 is dried by hot air injected into a casing. In such a way, in a flow of the cutting process, the efficiency of the cutting process is not deteriorated, and a deodorizing function is obtained. Also, a dimension variation of the object to be cut can be prevented.

摘要： PURPOSE:To easily smooth out the creases of cloth by setting a crease smoothing bar having protuberences on the upper face under a piece of cloth, holding it at one side thereof, and having the crease smoothing bar movalble relatively with respect to a cloth keeper which presses the cloth on the crease smoothing bar. CONSTITUTION:A piece of cloth 16 is spread on a manufacturing table 1 and held at one side by a cloth keeper 2, and a crease smoothing bar 9 is placed under the cloth 16. Then the smoothing bar 9 is moved apart from the cloth keeper 2 in the direction of an arrow A so that the cloth 16 is subjected to the force in the direction of an arrow B by the protuberences 9a formed on said crease smoothing bar 9, that is, the cloth 16 is tensed widthwise from the center thereof to the opposed sides to smooth out the creases of the cloth 16. The smoothed part of the cloth 16 remains on the manufacturing table 1 on the lower side of the crease smoothing bar 9.

摘要： PURPOSE:To irradiate the inclined surface of a knife edge shape with a laser beam which passes through a work and to divert it downward without reflecting it upward by providing vertically metallic thin plates for placing a work at an interval of a cavity to each other and forming an upward knife shape in a reflecting member of a supporting member for supporting these metallic thin plates. CONSTITUTION:Plural pieces of metallic thin plates 21 of Al are provided at an interval of a cavity to each other in a state that they are erected vertically. Between each metallic thin plate 21, a reflecting member 22 of a lozenge-shaped washer shape is placed by turning a lozenge-shaped knife edge shape upward. The reflecting member 22 and the metallic thin plates are allowed to pass through so as to be orthogonal to the moving direction by a round bar 23 and formed as one body with a work receiving table with a lock nut 24. Subsequently, a sheet-like work 1 is placed on the upper end of the metallic thin plate 21 provided vertically. A laser beam which irradiates the work 1 and is made incident at a max. incident angle theta, irradiates the tip side face of the knife edge shape of the reflecting member 22, and the laser beam is not reflected upward but reflected downward, and diverted.
