摘要： A therapeutic bed is arranged so that its inclination is adjusted by a bed inclination adjusting device provided to a rotation drive device disposed in a Y-direction moving device. The bed inclination adjusting device supports the therapeutic bed at three points by its three inclination adjusters. Each of the inclination adjusters converts the rotation of a motor into the rectilinear motion of a slider, and varies the level of a universal joint provided to the therapeutic bed by a support rod rotatably attached to the slider. This allows the inclination angle of the therapeutic bed to be varied. The provision of the bed inclination adjusting device reduces the number of drive devices for positioning the therapeutic bed, thereby decreasing the cumulative value of errors in all drive devices.

摘要： A widthwise-compressing machine for applying a compression force through press tools to a material (1) to reduce a width of the material while applying vibrations to said material (1) to forcibly vibrate said material has a compression unit (3) for producing a compression force forming a working force, and a vibration-applying unit (4) for applying the vibration to said material (1). The vibration-applying unit (4) is provided independently of the compression unit (3). In the widthwise-compressing machine, when the material (1) is plastically worked, the material can be vibrated at an extremely high frequency to make it possible to resonate the material, thereby allowing the plastic-deformation thereof to be promoted.

摘要： PROBLEM TO BE SOLVED: To increase a number of generating times of vibration per one turn of a valve unit, so as to obtain a high vibration frequency even at a low angular speed, by making a reciprocating motion of an actuator by only rotating the valve unit without reciprocating an in-valve movable part. SOLUTION: Cylindrical holes 8a to 8f of quantity equal to a control port or more are provided in a valve unit 1, on the other hand, sleeves 9, 10 and 11, 12 and flow paths 13, 14 and 15, 16 are provided in casings 2, 3, the control ports 17, 18 are connected to an inner circumferential part of the sleeves 9, 10, and a supply/discharge port 19, 20 is connected to the flow paths 13, 14. Since an inflow/outflow is repeated by the same number of times to a number of the cylindrical holes while the valve unit 1 makes one turn, an actuator makes a reciprocating motion by a vibration frequency in proportion to a number of the cylindrical holes and an angular speed of the valve unit. Accordingly, without making a reciprocating motion of the valve unit, a high vibration frequency is obtained even at a low rotational speed, so that with no restriction by a limit or the like of the angular speed, a reciprocating motion of high vibration frequency can be easily realized.

摘要： PROBLEM TO BE SOLVED: To realize responsiveness and stability at the same time. SOLUTION: Cap-side chambers 28, 29 of hydraulic cylinders 10, 11 are connected to a hydraulic source 40 via servo valves 14, 15. Rod-side chambers 30, 31 are connected to a pressure arrangement unit 21 via channels 50, 51. The channels 50, 51 set switching selectors 54, 55 and also connect accumulators 60, 61 via variable throttles 58, 59. During the time a rolling machine works, the switching selectors 54, 55 are closed, and the channels 50, 51 connecting to the rod side chambers 30, 31 are terminated at the switching selectors 54, 55 and at the accumulators 60, 61. This hydraulic drafting device can obtain high responsibility, by enhancing the characteristic frequency of the rod side channels and can control with stability since the accumulators 60, 61 absorb the pressure fluctuation.
