摘要： An optical beam scanning device comprises optical beam scanning means for rotational polygonal mirror to deflect entering luminous flux and scan an object to be scanned with the luminous flux; pre-deflection optical system which shapes a luminous flux emitted from light source means to image the resultant luminous flux onto the optical beam scanning means; and imaging optical system which images the luminous flux from the optical beam scanning means onto the object to be scanned. In the optical beam scanning device, the imaging optical system comprises an imaging optical element that in the entire main scanning area for luminous flux from the optical beam scanning means, the central scanning position has a main scanning direction curvature different from that of the scanning position of the scanning end, and a scanning angle α0 [rad] at which the optical beam scanning means scans the object to be scanned with the luminous flux is defined by the following expression, α0≦π{(2/N)−(Vr/3)×10−7} wherein N indicates the number of surfaces of the rotational polygonal mirror and Vr [r.p.m.] indicates the revolution of the rotational polygonal mirror.

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.
