A card connector including a base and a sheet metal cover combined with the base to form a flat hollow housing. Also, a plurality of pin-like elongate terminal members extend from an end and lateral walls of the sheet metal cover to be integral with the base, whereby a structure durable against an impact imposed when the housing falls is obtainable as well as the height of the card connector becomes smaller as the market requires.

A boring tool has a receiving part implemented as a borer body and a front part implemented as a borer head, which extend along a central axis and can be removably fastened to one another via driver connection. The driver connection has at least two coupling pairs which are separate from one another and are disposed eccentrically relative to the central axis. Each coupling pair is formed by interlocking coupling elements, namely a receiving pocket and a driver pin. The coupling elements have an asymmetrical cross-sectional area and widen with increasing distance to the central axis. Through this design, a reliable transmission of high torques is achieved with lower strains of the borer body in the area of the driver connection. Simultaneously, an automatic centering of the two tool parts to one another is performed.

The invention relates to an internal combustion engine with direct fuel injection comprising at least two adjacent inlet valves (1) per cylinder, a number of outlet valves (2), an essentially coaxial spark plug (3), an injection valve (4) and a piston (5,5'). The aim of the inventive engine is to provide an improved mixture preparation which is characterized by low fuel consumption and low exhaust emissions. To this end, the injection valve (4) is arranged between two of the adjacent inlet valves (1) and the section of the cylinder wall adjacent to said inlet valves (1). in addition, the piston (5,5') has a longitudinally extended combustion chamber cavity (6), whereby the combustion chamber cavity (6) essentially extends along the front surface of the piston (5,5') in the direction of the vertical projection of an injection stream (E) exiting from the injection valve (4). Said cavity also comprises a step (7) which essentially runs in a transversal direction.

The invention relates to a drive device (1) for a bicycle. The drive device (1) comprises a central housing (4), to which at least one swingarm (5, 6) is attached laterally which serves to hold a wheel (27) that is arranged such that it can rotate about a rotational axis (25). The at least one swingarm (5, 6) serves to receive at least one drive means (7, 8, 17, 18, 19).

A rig for drilling wells or holes at virtually any angle, from nearly horizontal to vertical, has a trailer mounted derrick which can be tilted to a desired angle, a top drive unit slidably mounted within such derrick and a hydraulic jacking apparatus. An automated pipe handling apparatus permits efficient transfer of pipe sections from the derrick to a truck, pipe rack or other storage facility.

The present invention provides a linear motor, wherein, a coil is fastened on a mass block that is suspended inside a housing, a first magnet and a second magnet that have opposite magnetic poles are symmetrically disposed at an upper side and at a lower side relative to the coil in the middle and positioned parallel to the centric plane of the coil, by arranging an upper magnetic steel and a lower magnetic steel at an upper side and at a lower side relative to the mass block in the middle and parallel to the mass block. In the linear motor of the present invention, the design route that utilizes coil motion to drive mass block motion is different from the traditional route that utilizes magnet motion to drive mass block motion. When the coil moves to either of the two lateral sides of the housing, both the first magnet and the second magnet simultaneously generate forces along a vertical direction of the housing, and as the first magnet and the second magnet having opposite magnetic poles are symmetrically disposed on both sides of the coil, the electromagnetic forces generated by the two magnets are equal in magnitude and opposite in direction, thus being counterbalanced with each other in the vertical direction, so as to ensure that the coil only moves back and forth in a horizontal direction, without generating vibration in a vertical direction, therefore, no noise related to vertical vibration is caused.

The invention is directed to a turbine with a housing mountable in a drill string and having an inlet opening and an outlet opening for a fluid conveyed through the drill string, and with an impeller arranged in the housing and adapted to be impinged upon by the fluid flowing into the housing, wherein the impeller is axially movably mounted and yieldably supported against the afflux direction in such a way that the supporting force of the yielding support increases as the axial movement of the impeller increases. To reduce the dependence of the turbine rotational frequency and turbine performance on the feed rate and to avoid overloading of the generator, the housing includes in the range of movement of the impeller a frontal first housing section of smaller inner diameter as seen in the afflux direction and a rear second housing section of larger inner diameter as seen in the afflux direction.

In an electric motor having a rotor (2) and, coaxial therewith, a stator (1), both contained in a frame (3), the motor being capable of rotating a member (4) about an axis of rotation coinciding with the axes of the rotor (2) and stator (1), the rotor (2) is connected in rotation to the member (4), is hollow and its interior houses a shaft (5) that supports both it (2) and the member (4), and the frame (3) of the motor is supported by the same shaft (5) and is connected by an attachment (6) to a structure that does not participate in the rotation.

A grinder has a hollow housing, a support rotatable in the housing about an upright axis, a lower annular grinding disk fixed atop and rotatable with the support, and an upper grinding disk nonrotatably fixed in the housing above the lower disk and forming therewith a radially extending annular grinding gap. The disks form with the housing an annular outlet chamber into which the gap opens radially outwardly. The housing forms an upwardly open intake into which the gap opens radially inward. An electrical drive is connected to the support for rotating the support and lower disk in the housing so that material charged into the intake is ground in the gap and expelled as particles into the output chamber. An angular-contact bearing is braced axially and radially between the support and the housing below the disks.
