The present invention relates to a multi-functional exercise apparatus, and particularly to a multi-functional exercise apparatus which is safe and allows various exercises with different setups to be performed by means of a single apparatus. The present invention, relating to a multi-functional exercise apparatus provided so as to impart a sense of stability to a user when exercising while at the same time allowing various exercises with different setups to be performed by means of a single apparatus, comprises: a plate-shaped body (A) forming the floor surface and having a space in the interior thereof; fixed frames (100) fixedly disposed upwardly on both sides of the body (A); rotatable frames disposed upwardly on both sides of the body (A); handle parts (200) connected on one side of the rotatable frames and provided so as to be movable forwards and backwards; and a foot plate part rotatably provided on upper surface of the body (A) and connected to the other side of the rotatable frames. The multi-functional exercise apparatus according to the present invention imparts a sense of stability to a user as the rotatable frame comprises a plurality of linked sections and connects the handle parts and foot plate part, allowing the user to exercise by rotating not the entire rotatable frames but only the handle parts which are comparatively short compared to the rotatable frames. Furthermore, each linked section of the rotatable frames is rotatably attached to the handle part or to the side of the fixed frame, allowing the rotatable frames to stably transmit driving power from the handle parts (200) to the foot plate part and to be changed so as to allow various exercises with different setups to be performed.

A pivot mechanism of the synchronous hinge device is applied to a foldable electronic apparatus. The pivot mechanism can be stably rotated and the distance between two shafts of the dual-shaft hinge is shortened, whereby the electronic device can be smoothly rotated and have a miniaturized and lightweight structure. The pivot mechanism includes a driver disposed on a first shaft and a reactor disposed on a second shaft and a link unit. Spur gears and conical (bevel) gears are respectively disposed at two ends of the link unit and the driver and the reactor. The Spur gears and conical (bevel) gears are engaged with each other to transmit power, whereby the first shaft with the driver and the second shaft with the reactor can be stably synchronously rotated in reverse directions.

Subsea turbomachine for boosting the pressure of petroleum fluid flow from subsea petroleum productions wells or systems, comprising an electric motor and a compressor or pump driven by the electric motor, a fluid inlet and a fluid outlet, distinctive that the turbomachine comprises a pressure housing common for the electric motor or stator, and compressor, pump or rotor; a magnetic gear inside the common pressure housing for operative connection between the motor or stator and compressor, pump or rotor; and a partition inside the common pressure housing, arranged so as to separate a motor or stator compartment from a compressor, pump or rotor compartment.

An image forming apparatus including: a driven rotational body that is detachable from the image forming apparatus and includes a driven connecting part; a transmission member that receives a rotational power and includes a driving connecting part provided along a direction of a rotational axial line of the driven rotational body; and an assembling member that receives the rotational power from the transmission member, transmits the rotational power to the driven rotational body to rotate the driven rotational body, and includes a driven side assembling part to connect to the driven connecting part, and a driving side assembling part to connect to the driving connecting part.

The invention discloses a conveying line with a blocking effect. The conveying line comprises two symmetric speed chains arranged in parallel. The two speed chains are arranged on two fixed mounting plates correspondingly. Drive gears are arranged at the bottoms of the middles of the two speed chains correspondingly. The two drive gears are arranged on a hexagonal bar in a sleeving mode and rotate along with the hexagonal bar. One end of the hexagonal bar is connected with a gear motor. Left-handed thread and right-handed thread screws are arranged in the positions, on the two sides of the hexagonal bar, of a bottom plate framework. The two Left-handed thread and right-handed thread screws are in threaded connection with the corresponding fixed mounting plates. Two blocking mechanisms are further symmetrically arranged between the two speed chains. Each blocking mechanism comprises a fixed mounting frame, and a jacking air cylinder is arranged one each fixed mounting frame. According to the conveying line with the blocking effect, the width of a conveying belt can be adjusted, the structure is compact, positioning can be conducted, and the blocking effect is good.
