An exercise device capable of simultaneously exercising a plurality of muscle groups, which includes an exercise chair mounted to a base, the exercise chair having a pivotally-resistant seat back. The exercise device further includes large, curvilinear conduits through which pass adjustably-resistant elastic bands with grips fixedly attached to the elastic bands proximate the upper and lower ends of the curvilinear conduits, which curvilinear conduits are laterally spaced, one on each side of the exercise chair. The exercise device further includes a resistive foot platform positioned at the front end of the base, which resistive foot platform is moveably engaged with the exercise chair. The exercise device further includes a resistive seated-row grip positioned at the front end of the base that permits cardiovascular exercise.

A magnetic structure for use in a magnetic head for avoiding stray field writing. The magnetic structure can be for example a magnetic shield or could be a magnetic pole of a write head and is particularly advantageous for use in a perpendicular recording system, because such perpendicular recording systems are especially susceptible to stray field writing. The magnetic structure includes a forward protruding portion that extends toward the air bearing surface (ABS) of the head also includes first and second wing portions that extend laterally from the forward protruding portion. The wing portions each have includes an inner constant recess portion, and an outer tapered portion. The inner constant recess portion of each wing prevents stray field writing while also preventing magnetic saturation, the outer tapered portions, which taper away from the ABS as they extend laterally outward, further prevent stray field writing by removing the outer corners of the shield away from the ABS.

A roller guide (1) for guiding stock in a longitudinal feeding direction (A) toward a pair of rolls for shaping the stock. The roller guide comprises a frame arrangement (2), a pair of guide rollers (3, 4) configured to, in a closed position, engage opposite surface portions of the stock,and positioning means for adjusting a lateral distance between the guide rollers. The roller guide further comprises detection means (13) configured to detect a longitudinal position of a piece of stock (20) with respect to the guide rollers. The positioning means is configured to adjust the lateral distance between the guide rollers in response to said detection.

The invention discloses a natural gas pipe automatic cleaner. The natural gas pipe automatic cleaner comprises a linkage device, a connecting rod, a moving wheel, a height extension adjusting supportleg, a protective cover, a machine body, a rocking rod, a handle, a cleaning head and a leg cover; the side surfaces of the top end of the height extension adjusting support leg are respectively fixedon the two sides of the machine body; the two ends of the connecting rod penetrate through the bottom of the left end of the height extension adjusting support leg to connect into the moving wheel; and the bottom of the protective cover is welded with the bottom of the machine body. The linkage device of the natural gas pipe automatic cleaner can control the cleaning diameter of a fixed brush through an internal mechanical structure to finally adapt to the internal diameter of a natural gas pipe; meanwhile, the height extension adjusting support leg can be automatically adjusted under the condition of external force, so that the practical value of the cleaner can be improved, and meanwhile, the working efficiency is improved; and the transverse distance of the fixed brush can be adjustedunder the condition of hand shaking by a middle connecting device, so that the use convenience is improved.

The invention relates to the technical field of workpiece clamping devices, in particular to a pressing clamping device. A base is arranged on a transverse part of an L-shaped bracket; at least one blocking ring with a notch is arranged on a vertical part; the blocking ring is connected with the vertical part through a supporting rod; the two ends, in the notch, of the blocking ring outwards extend to form extension rods; screw holes are formed in the extension rods; an air cylinder is arranged in the blocking ring; and a telescopic end of the air cylinder faces towards the base. The pressing clamping device is good in clamping effect.

The invention discloses a multi-rotor-wing auxiliary pollination machine for producing seeds and increasing the yield. The machine comprises a multi-rotor-wing aircraft, and the multi-rotor-wing aircraft is characterized in that two air blowing fans are assembled at the tail of a rack of the multi-rotor-wing aircraft through a connection frame, wherein the air outlet direction of the two air blowing fans is 45-degree downwards relative to the plane of a machine body and 45-degree outwards relative to the direction of the machine tail. When the multi-rotor-wing auxiliary pollination machine for producing the seeds and increasing the yield flies, generated downward spinning air flow can reach force 5-6 wind power, stamens of corn male plants can be shaken forcefully, pollen in the stamens is shaken off and made to fly away, when the multi-rotor-wing machine flies over the corn male plants, air flow generated by the tail of the machine goes up to drive the pollen to spread toward the two sides of the flight direction, and thereby the transverse distance and area of pollen spreading are increased, so that the pollen can adhere to female plants more uniformly, the pollination rate of the female plants is raised, the traditional plantation mode that one corn male plant pollinates three corn female plants can be improved to the extent that one corn male plant pollinates ten to fifteen corn female plants, the pollination rate is raised, pollination quality is improved, and the purposes of increasing the yield and enhancing the effect are achieved.
