An active/self-sensing compensating hydrostatic bearing is disposed between first and second structures to allow relative movement between the first and second structures. The hydrostatic bearing includes a body and a compensator. The body, fixed to the first structure and separated from the second structure by a first gap, has a chamber and an input passage and an output passage both communicating with the chamber. The compensator is disposed in the chamber. A compensating passage, communicating with the input passage and the output passage, is formed between the body and the compensator. A pressurized fluid flows from the input passage to the output passage through the compensating passage, and the pressurized fluid in the output passage flows to the first gap to maintain the stability and the rigidity for the relative movement between the first and second structures. A hydrostatic bearing module using the hydrostatic bearing is also disclosed.

An electronic apparatus with an active posture control function includes a body assembly, an accelerometer, a driving device and a controller. The body assembly includes a first body and a second body pivotally connected to the first body. The accelerometer mounted on the body assembly senses acceleration of the body assembly to output an acceleration signal. The driving device mounted on the body assembly drives at least one of the first body and the second body. The controller, mounted on the body assembly and electrically connected to the accelerometer and the driving device, receives the acceleration signal, judges whether the acceleration signal is higher than a predetermined level, and controls the driving device to adjust an included angle between the first body and the second body when the acceleration signal is higher than the predetermined level.

A three-wheeled vehicle has an auxiliary steering system which is made up of a front frame, a rear frame, a bearing element, a gear set, and a transmission element. The gear set comprises a first gear and a second gear. The first gear is fastened with the front frame while the second gear is fastened rotatably with the rear frame such that the second gear is engageable directly or indirectly with the first gear. The front frame can be caused to swivel in relation to the rear frame by means of the second gear which is actuated by an angular motion of the front fork of the vehicle when the handlebar of the vehicle is turned. The transmission element serves to transmit the angular motion of the front fork to the second gear. The auxiliary steering system is therefore capable of causing the center of gravity of a rider of the vehicle in motion to move toward a direction in which the handlebar of the vehicle is turned, thereby causing the centrifugal force exerting on the vehicle rider to be canceled out.

摘要:
A method of fabricating carbon nanotube (CNT) pattern includes the following steps. First, one surface of a first transparent substrate is denoted as the first surface. A CNT thin film layer is coated on the first surface by a thin film deposition method. Then, a second substrate is disposed opposite to the first surface coated with a CNT thin film layer. By adopting a laser transfer method, a laser source irradiates on the CNT thin film layer coated on the fist surface, such that the CNT on the irradiated area explodes to depart from the first surface due to the high temperature resulted from the energy imparted by the laser light, so as to form a CNT pattern on the opposite second substrate.
