The invention discloses a method and device for cleaning space debris. According to the method, electromagnetic force is applied to the space debris running on an original orbit; the speed and/or direction of the space debris are/is changed under the action of the electromagnetic force; the space debris of which the speed is changed is changed to run on a new orbit under the action of gravity; at least the height of the perigee of the space debris on the new orbit is smaller than the height of the perigee of the space debris on the original orbit; the space debris running on the new orbit finally falls into the atmosphere of the earth under the action of atmosphere resistance. The device comprises a satellite bearing platform which is provided with an electric field device cleaning the space debris or a magnetic field device cleaning the space debris or a combination of the electric field device and the magnetic field device. The method and device for cleaning the space debris do not have high requirements for the accuracy of position detection of the space debris, micro space debris can be effectively cleaned, solar energy can be fully utilized for power generation, and self-carried energy is saved. The device for cleaning the space debris has the advantages of being simple in structure, low in manufacturing cost, and better in pulse action effect.

An improved vacuum drilling system and drill bit includes a generally hollow vacuum drill bit with one or more chip inlets arranged proximate to one or more cutting surfaces. The drill bit also includes grooves along its exterior. When the drill bit is guided by a bushing or guide hole, the grooves serve to reduce the friction therebetween. The grooves can also convey air for cooling and improved chip collection.

The surgical nail, here in the form of an intramedullary nail, has a central axis, a longitudinal borehole with a diameter D extending coaxially with the central axis, a casing with an inner surface and a transverse borehole, extending transversely to the central axis with the cross-sectional profile F and the borehole axis. A component, which narrows the cross-sectional profile F, is provided in the longitudinal borehole in the region of the transverse borehole. By these means, the clearance, which is usually present between the medullary nail and the locking screws that have been introduced therein, can be eliminated without risk and an improved holding force as well as an improved guiding effect between the locking screw and the medullary nail can be achieved.

A displacement detecting device has a diffraction grating, grating interferometers, and relative position information output sections. The grating interferometers have a light source, reflectors, a beam splitter, and light receiving sections. The reflectors reflect 1st-order diffracted lights diffracted by the diffraction grating, and cause the reflected 1st-order diffracted lights to be incident at a position substantially identical to the position at which the light from the light source is irradiated. Furthermore, the reflectors cause the 1st-order diffracted lights to be incident on the diffraction grating at an angle different to either the incidence angle of the light from the light source incident on the diffraction grating or the angle at which the 1st-order diffracted lights are transmitted through or reflected by the diffraction grating.

The end plate includes mating structure adapted to mate and securely couple with at least one end of the at least one bone plate. The system preferably includes several endplates and bone plates to accommodate anatomical structures of various sizes.

The invention relates to a sealing ring for sealing a piston rod of a piston compressor. The sealing ring comprises three segments, wherein the segments have portions extending in the circumferential direction of the sealing ring, which form an overlapping joint. The overlapping joint brings about an excellent sealing effect in the axial direction.

It is made easy to design so that the sliding resistance, when subjected to an impact in the axial direction, is kept within a prescribed value. A constant velocity universal joint is provided, which has track grooves extending in the axial direction on the outer circumference surface of the inner ring, and formed in an intersecting arrangement, and which also embeds balls in these track grooves. In this constant velocity universal joint, the cross-sectional shape of the track groove of the inner ring is constituted by a Gothic arch portion which is a Gothic arch shape up to a location that exceeds a contact point where the groove angular contacts with the ball, and a straight-line portion which is formed continuously with the Gothic arch portion, between the location exceeding the contact point and a shoulder portion of the track groove, and which extends in the direction of the tangent line at the location that exceeds the contact point.

There is disclosed a scroll compressor having an object of stabilizing the moving of an orbit scroll while suppressing the start load of the scroll compressor. In the scroll compressor, a slide bush having a slide face forming a predetermined angle with respect to the direction of gas load of a gas in a compression chamber is interposed on an eccentric shaft of a shaft for driving the orbit scroll, so that when the load of the gas in the compression chamber is applied, the eccentric amount of the eccentric shaft increases. The scroll compressor includes a spring member interposed between the slide bush and the eccentric shaft and configured to constantly urge the eccentric shaft to decrease the eccentric amount of the eccentric shaft, and this spring member urges the eccentric shaft to press the eccentric shaft onto the slide face of the slide bush.

Each contact includes a contact engaging portion (3212, 3312) extending through the slots. At least one of the fingers and the contact engaging portions includes a reduced-dimension-portion such that clearance between the contact engaging portion and the slot is increased.

A vane pump includes a plurality of vanes and a vane cam. Each of the vanes is housed in a corresponding one of multiple slits in an outer periphery of a rotor in a manner of being capable of protruding from, and retracting in, the slit. Each of the vanes has both end faces formed into curved surfaces in a plane perpendicular to a rotational axis of the rotor. The vane cam is disposed in contact with an end portion of the rotor such that an outer peripheral surface thereof contacts inner peripheral side end portions of all vanes to thereby forcedly make the vanes protrude and retract. The vane cam is movable so as to vary an amount of eccentricity relative to a drive shaft.

A nursing bed is provided that has a height adjustable base, in which a rotary hinge is attached in a substantially countersunk arrangement. The rotary hinge connects the base to an intermediate frame on which the actual reclining frame is installed. In this way, a bed framework is obtained, which, after subtracting the height of support feet, has a very small structural height, so that in the lowest position, the distance from top edge of the mattress from the floor corresponds to the length of a lower leg, while simultaneously there is still space underneath the base.
