    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.

    摘要： Tap arithmetic units and first delay circuits are arranged alternately. Each of the tap arithmetic units has a full-adder array for multiplying an input signal which has been sampled at regular intervals and coefficients, a second pipeline delay circuit for delaying outputs of the full-adder array by a predetermined time and an adder circuit for adding outputs of the second delay circuits. The first and second delay circuits are timed to the preceding tap arithmetic unit for arithmetic operations. The use of the second delay circuit for the timing of arithmetic operations permits the arrangement of the first delay circuit to be simplified.

    摘要： Disclosed is a push-switch that comprises a tubular case, a fixed electrical contact in the tubular case, an operation shaft in the tubular case, a contact piece held by a holding part to the operation shaft, a resilient member for urging the operation shaft, and a cover for closing the tubular case. The holding part defines grooves and a recess between the grooves, and the contact piece has a fixing part positioned within the grooves and a protrusion positioned within the recess. The contact piece also includes an arm having an electrical contact thereon for sliding engagement with the fixed electrical contact upon depression of the operation shaft, and the cover includes an opening. The cover also includes a rib projecting downwardly from a lower side thereof, with an inner side of the rib being flush with a contact surface of the fixed electrical contact. To assemble the push-switch the contact piece is attached to the operation shaft via the holding part. Then, the operation shaft is inserted into the opening of the cover such that the electrical contact on the arm of the contact piece flexibly engages an inner side of the rib. Then, while maintaining the flexible engagement between the electrical contact on the arm and the inner side of the rib, the cover is combined with the tubular case.

    摘要： A cylindrical mounting apparatus includes: a cylindrical mount having an elastic body elastically connecting an inner and outer sleeve disposed in mutually spaced-apart relation; and a bracket independent of the cylindrical mount and having a pair of support plates opposed to each other with a spacing therebetween. The mount is interposed between the pair of support plates and fastened to the bracket by a mounting bolt extending through a bore of the inner sleeve across the support plates. Two positioning protrusions protrude from an inside surface of one support plate toward the other, and a mounting plate is disposed on one axial end of the inner sleeve extending diametrically. A recessed engaging portion of the mounting plate is brought into engagement with the positioning projections to place the mounting plate in a predetermined position about its center axis on the support plate.

    摘要： 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.

    摘要： A delay circuit comprising a plurality of clocked inverters coupled cascade form. Each clocked inverter includes a plurality of MOS FETs. The circuit further comprises delay time-controlling MOS FETs connected in parallel to the MOS FETs of the clocked inverters, which are controlled by clock signals. When the delay time-controlling MOS FETs are turned on, the clocked inverters function as ordinary inverters. Conversely, when the delay time-controlling MOS FETs are turned off, the clocked inverters perform their own functions. Hence, one of two different delay times can be selected.

    摘要： A vibration damping bushing including: an inner axial member; an outer cylindrical member through which the inner axial member is inserted; a main rubber elastic body elastically connecting the two members; and a stopper member that is fitted onto the inner axial member as a component of a first stopper mechanism that limits relative displacement of the inner axial member against the outer cylindrical member to one side in an axial direction. The inner axial member is formed with a latching depression that opens toward an outer periphery thereof, and the stopper member is provided with a latching piece that protrudes outward in the axial direction. The latching piece is engaged with the latching depression so as to provide a slipping out prevention mechanism for preventing the stopper member from slipping out from the inner axial member.
