摘要： An oil-country-tubular threaded joint can withstand tensile forces, and in addition, other forces such as compression and bending forces, thus producing highly improved characteristics in regard to the prevention of fluid leakage. The oil-country-tubular threaded joint is formed of male screw threads and female screw threads which have a load face whose load flank angles are in a range of −3° to −25°, in which the load flank angles are varied at a position at which the load face is divided in the height direction of the male screw thread into an upper side and a lower side so that an upper load flank angle is smaller than a lower load flank angle by 0.5° to 2.0°. Also, a thread-machining apparatus for the oil-country-tubular threaded joint uses chasers having cutting edges which are shaped so as to correspond to thread shapes for machining screw threads whose flank angles are partly of negative values for the oil-country-tubular threaded joint. In the apparatus, the cutting edges which are to be used from the beginning to the end of thread-machining are arranged on the individual chasers sequentially according to the shape, and the chasers are on one rotational body so as to machine screw threads at a rate of one pitch per rotation of the rotational body. This allows negative screw threads of quality higher than in conventional cases to be cut in a reduced time.

摘要： It is an object of the invention to prevent a lapping member from being cut by an edge of a slider when the edge is chamfered by lapping it with the lapping member. A slider held by a slider holding jig according to the invention is put in contact with a diamond lapping sheet. A load applying portion moves weights provided in the form of a plurality of stages downward from a state in which the lower end of a shaft portion of the weight at the bottom stage is located above the slider holding jig without contacting the slider holding jig, thereby loading the slider holding jig with the weights sequentially from the bottom stage.

摘要： A marker is provided outside the probe arrangement region of the lower surface of a probe card. In identifying positions of probes, the marker is recognized by a camera before the distal end of a reference probe is recognized. The camera is then moved from the position of the marker based on information about the relative position stored in advance to recognize the distal end of the reference probe. The camera is moved complementarily to make a reference point in the view of the camera and the distal end of the reference probe align with each other. Furthermore, where the same operation is performed for another reference probe, a deviation of the probes in the .theta. direction is calculated as .theta. correction data.

摘要： A printer comprises a removable process unit which includes a photoconductive drum and an image forming section for forming an image on the drum. The process unit is provided with a removing member for removing dust from a transfer medium adhering to an aligning roller and a dust storage section for storing the dust removed by the removing member. The storage capacity of the dust storage section is larger than a capacity equivalent to the volume of the dust removed as the transfer medium corresponding in quantity to the service life of the process unit is processed.
