The present invention relates to an improvement in an exhaust system structure for a motorcycle. A motorcycle has an engine disposed between front and rear wheels, an exhaust pipe extending from the engine, and a silencer connected to the exhaust pipe for discharging exhaust gases. The silencer, which is a heavy object, is of the type having a gas outlet disposed near a gas inlet. The silencer is disposed below the engine with the gas inlet facing toward the rear wheel, and the exhaust pipe extends to a position near the rear wheel and is connected to the gas inlet of the silencer. By elongating the length of the exhaust pipe and placing the silencer under the engine, the exhaust system performs sufficiently with high output engines, while at the same time lowers the center of gravity of a motorcycle body and balances the weight of the motorcycle body in its longitudinal direction.

A tether system include tethers each having an upper section (1) attached to a tension leg platform (TLP) (4), and each upper section has a large diameter so that the upper section (1) is positively bouyant. This buoyancy can be designed to compensate for the weight of the lower section (2) of each tether, so as to make the total buoyancy of each tether closer to neutral. The selection process for each section is driven by requirements for buoyancy, stiffness and external pressure resistance.

An auxiliary opening/closing mechanism for a cover of a roasting stove, the mechanism can improve the roasting stove to eliminate the defect resided in using a thick and heavy metallic roasting stove cover which makes uneasy for opening and closing the auxiliary mechanism is connected with a rope on the rear of it, the rope extends down along the back of the roasting stove, and one end of the rope has a pending counterbalance weight, the weight of the counterbalance weight pulls the roasting stove cover to help to open it, thereby the roasting stove cover gets rid of the trouble of being uneasy for opening and closing being due to its thickness and heaviness.

Provided is a telescopic handwriting pen for PDA or cellular phone. In one embodiment, the pen comprises tubelike inner, intermediate, and outer sections and first and second coupling assemblies fitted in front ends of the inner and intermediate sections. Either coupling assembly includes annular grooves with O-rings put thereon, an annular recess between the grooves filled with lubricating oil, and a rear extension secured to the inner or intermediate section. A writing head is fitted in a front end of the outer section and comprises a channel in fluid communication with the external and inside of the second coupling assembly. Stop mechanisms are provided in rear ends of the outer and intermediate sections for preventing an inside section from disengaging another section while sliding therein. The pen can carry out a smooth sliding and has a balanced weight.
