摘要:
In a laser beam machine tool, the problems of power losses, misalignment, high cost, and other problems associated with moving laser heads are eliminated by using a five-axis table in which a biaxial work holder, capable of rotating and tilting a workpiece is mounted on a three-axis table mechanism. In the three-axis table mechanism, an X-axis table is supported on linear motion bearings in overlapping relationship on a Y-axis table, which is, in turn, supported on linear motion bearings on a vertically movable Z-axis table, which is also supported in linear motion bearings. The X-axis, Y-axis and Z-axis tables are driven by servo motors through ball screws so that backlash is avoided.

A work rotating device for a laser beam machine utilizes a work-supporting bed rotatable by a speed reducer mounted on a frame adapted to rest on a table of the laser beam machine. In a first embodiment, the speed reducer is fixed to the frame, and the frame has two orthogonal surfaces alternatively engageable with the table so that the axis of rotation of the work can be either vertical or horizontal. In a second embodiment, the speed reducer is manually tiltable in the frame by direct manual rotation of a shaft on which the speed reducer is mounted. In a third embodiment, the speed reducer through which the work is rotated is mounted on a shaft which is connected to a handwheel through another speed reducer. In a fourth embodiment, the speed reducer through which the work is rotated is tilted by a servo motor operating through a speed reducer.

A liquid propellant tank for storing a liquid propellant A and supplying vapor produced by evaporation of part of the liquid propellant A to an external location comprises a tank body for storing the liquid propellant A, and a plurality of holder plates arranged inside the tank body, around an axis L of the tank body. The holder plates cause the liquid propellant A to adhere to them by surface tension, thereby establishing, inside the tank body, a liquid propellant holding area LA in which the liquid propellant A is held and a gas accumulation area GA in which vapor produced by evaporation of part of the liquid propellant A accumulates. The tank body has a propellant inlet open into the liquid propellant holding area LA and a gas outlet open into the gas accumulation area GA.

The grasping apparatus includes a grasping portion for grasping a workpiece. This grasping portion has i) pawl portions having squeezing portions that squeeze the workpiece, and ii) contact portions, each of which has an inner bag made of elastic material, and a granular substance that is filled in the inner bag. The contact portions are attached to portions of the squeezing portions that contact the workpiece, and harden the granular substance while keeping it in an appropriate shape by increasing a volume ratio of the granular substance to an inner volume of the inner bags. Retaining portions that have concavo-convex shapes are formed on the attaching surfaces that are portions of the squeezing portions that the contact portions attach to.

A method for removing a wrapped yarn coil of an initial yarn portion of a package; the wrapped yarn coil being wound on a bobbin while being gripped by a slit-like groove formed on the bobbin end along a peripheral circle of the bobbin, and being followed by a transfer tail; including steps ofsevering the wrapped yarn coil at a position on the bobbin end in which the slit-like groove does not exist,while holding the severed ends of the wrapped yarn coil by suction, gripping the severed ends by grippers, andremoving the wrapped yarn coil from the slit-like groove along the periphery of the bobbin while rotating the grippers in the twisting direction so that a twist is imparted to the wrapped yarn coil held by the grippers.
摘要:
A coin receiving apparatus for a vending machine capable of accurately checking a coin diameter as well as other coin characteristics such as material and a surface pattern for discriminating a true coin from a false one and receiving the former and rejecting the latter. The diameter and other coin characteristics are detected by examining peak values of output waveshapes of coin detectors by means of a window circuit. A single window circuit is provided for each denomination and upper and lower limit values of the window circuit are automatically changed in accordance with a coin characteristic under examination. Frequencies of excitation signals of the various coin detectors are also automatically changed. If a plurality of coins are successively inserted in the coin receiving apparatus without a sufficient time interval, discrimination of the inserted coins is inhibited and the inserted coins are returned.
