Abstract: When electric elements are formed on a ceramic bar or the like, the positional displacement of the respective elements occurs due to a division exposing process or the like. An object of the present invention is to provide a device and a method which unify the non-polished portion of the respective elements by conducting polishing while a complicated deformation or the like is given to the ceramic bar. To achieve this object, the ceramic bar or like is held by using a jig, and a plurality of loads are applied to portions of the jig where the ceramic bar or the like is held, to thereby deform the ceramic bar or the like and polish the element in that state. In this situation the load applied points are disposed so as to avoid the boundaries of the division exposure.

Abstract: An apparatus for lapping a workpiece including a plurality of magnetic heads supported by a tool is disclosed. The lapping apparatus comprises a rotary lapping table, a lapping head attachment frame, an adjuster ring resiliently supported by the frame, a lapping head attached to the adjuster ring, a tilting assembly attached to the lapping head, and an up and down movable back plate pivotally attached to the lapping head. The apparatus further comprises first actuators or cylinders for correcting balance by applying forces on right and left sides of the pivotal point of the back plate, and second actuators or cylinders for correcting bow of the workpiece by applying operating forces on a plurality of predetermined locations of the tool so that the moving directions of movable parts of the second actuator means are substantially parallel with the directions of the operating forces.

Abstract: Disclosed herein is a die coater comprising a die composed of upper and lower mold-pieces which form a manifold and a slit extending from the manifold, an inner deckle shaft disposed in the manifold, a deckle disposed in the slit in a fluid-tight state, and a deckle guide; the inner deckle shaft having a fluid-tight portion near an end thereof and capable of moving with its fluid-tight state kept, the deckle and the deckle guide being secured to the inner deckle shaft, and the deckle being connected with the fluid-tight portion of the inner deckle shaft.

Abstract: A direct coal fired type gas turbine combined power generation system comprises a pressurized gasifier provided with a gas outlet, a gas cooling unit provided for the gas outlet of the pressurized gasifier, a high temperature dust collector unit connected through a line to a gas cooling unit, a gas turbine combustor connected through a line to the dust collector unit, a gas turbine connected through a line to the gas turbine combustor, a gas turbine generator connected through an output shaft to the gas turbine, a heat recovery boiler connected to the gas turbine, a gas refining unit disposed in association with the heat recovery boiler and connected through a line at an upstream side thereof to the gas cooling unit, a steam turbine connected through a line to a downstream side of the heat recovery boiler and the gas cooling unit through a line and a steam turbine generator connected through an output shaft to the steam turbine.

Abstract: An apparatus for inspecting the outward appearance of each of IC packages stored in an embossed tape includes a drive wheel having an outer periphery about which the embossed tape is wound. The drive wheel is rotatable in a vertical plane for moving the embossed tape. A pair of cameras are so mounted as to face the outer periphery of the drive wheel at its upwardly and downwardly moving portions, respectively, and are used to produce two different images of each IC package from two different angles through a cover tape bonded to the embossed tape for enclosing the IC packages. The apparatus prevents any diffused reflection of light by the cover tape and any inclination of each IC package during its inspection.

Abstract: A nut runner for applying torque to a workpiece such as nut, bolt or the like positioned at a right-angle to the fastening device. The nut runner includes a motor, a speed reduction gear assembly, a right-angle bevel gear system, a planetary gear system, an in-line torque transducer disposed between the bevel gear system and the planetary gear system, a torque reading transmitter, and a workpiece engaging member. The bevel gear system, planetary gear system and torque transducer form a concentrated assembly which provides for a compact nut runner to access confined assembly areas. The motor causes the engaging member to rotate. The torque transducer senses the torque and the torque reading transmitter sends the reading to an operator or controller which interrupts the power supply to the nut runner when a predetermined torque is reached.

Abstract: A device for verifying or measuring a minimum value of a previously applied torque on a workpiece such as bolt, nut, etc., includes a motor, a reduction gear assembly, a torque transducer and a fastener engaging member, including a rotatably spindle. The motor causes the spindle to rotate. A torsion bar interposed the spindle and the motor absorbs the inertia of the motor when the motor is stopped to minimize torque overshoot, as well as taking up the rotation generated by the motor immediately upon engagement with a workpiece. An angle encoder senses any rotation of the workpiece caused by the rotation of the spindle. Any rotation of the workpiece means that the previously applied torque is below a minimum predetermined value.

Abstract: A method for fastening together two or more parts with a fastener through fastening holes where either the fastener is misaligned with the holes or the fastener and one of the parts are both misaligned with the fastening hole of the other part. A depression having a throughbore is formed in one part and defines one fastening hole and cooperates with a self-tapping fastener to fasten the parts together and bring the fastener into alignment with the parts. The depression deforms to accomplish the alignment of the fastener and the parts.

Abstract: There is disclosed a constant-speed, fastener tightening method using a nut runner for setting the final tightened state of the fastener in terms of tightening torque, characterized in that the fastener is tightened by maintaining the rotative speed of the nut runner at a constant speed regardless of variations in tightening loads.

Abstract: An apparatus for automatically feeding and setting stud bolts. The apparatus comprises a parts feeder unit for axially arranging stud bolts having threaded portions of different lengths on the opposite ends thereof in a low, a bolt orienting unit for directing stud bolts in one direction, an escapement unit for correctly feeding stud bolts one by one, an impact wrench unit for screwing stud bolts into intended work to set them in position, a pneumatic pressure control unit for feeding compressed air produced by a compressor into the escapement unit and impact wrench unit, and an electric control unit for electrically controlling the units, the arrangement being such that all operations which end up with screwing stud bolts into intended work to set them in position are carried out mechanically.
