摘要:
The present invention relates to a motor driving system. The motor driving system includes a motor, a transmission member, a follower member, a position-detecting light emitter, a position-detecting light receiver, and a positioning-status sensing element. The positioning-status sensing element includes a plurality of notches or openings. The positioning-status sensing element is moved between the position-detecting light emitter and the position-detecting light receiver such that a light beam emitted from the position-detecting light emitter is successively penetrated through the notches or openings to be received by the position-detecting light receiver. According to the light-receiving status of the position-detecting light receiver, the speed of the motor is reduced.

An apparatus for applying dye material on an electrode to form a dye-sensitized solar cell includes a rotary unit and an electrode holding unit disposed around the rotary unit. The rotary unit is rotatable about a rotary axis and includes a dye tank for receiving liquid dye therein and a dye breaking unit disposed around the dye tank. The dye tank permits flow of the liquid dye therein to the dye breaking unit. The dye breaking unit breaks the liquid dye flowing from the dye tank into liquid droplets that move in the dye breaking unit due to centrifugal force. The rotary unit permits the liquid droplets to exit therefrom. The liquid droplets exiting the rotary unit are propelled toward an electrode on the electrode holding unit during rotation of the rotary unit.

The present invention discloses a method for catching particles having diameters size down to the nanometer level including a first step of increasing particle diameters of particles contained in an outlet gas from a fabrication process of nano-particles or an exhaust from a combustion; and a second step of introducing the resulting effluent from the first step into a rotating packed bed. The first step involves contacting the gas/exhaust with droplets or water vapor, creating collision of the nano-particles with the droplets or condensation of water vapor using the nano-particles as condensation nuclei, so that the size of the nano-particles increases to the micro level. The second step uses the minute water drops generated from and the hindrance of the rotating packed bed to catch the micro-particles in the gas/exhaust under a relatively high centrifugal force. The first step can occur in the rotating packed bed if the gas/exhaust is introduced directly into the rotating packed bed and has a sufficient long residence time in the rotating packed bed.

A high viscosity liquid is fed into a rotation pack bed at a position with a distance far enough from a rotation axis, creating a centrifugal force exerted on the high viscosity liquid overwhelming a drag thereof, so that it can flow radially through the rotation pack bed. A high pressure gas is introduced into the rotation pack bed peripherally and/or a suction force source is connected to a position near the rotation axis, so that a volatile component contained in the high viscosity fluid is entrained in the gas counter currently flowing through the rotation pack bed and withdrawn from the position near the rotation axis, or the volatile component exits from the position near the rotation axis in gas phase, and thus the volatile component is removed from the high viscosity liquid. A second fluid can also be fed into the rotation pack bed to react with the high viscosity liquid, so that a reaction product is formed, and a volatile side product is removed at the same time.

A method is used to remove an unreacted alcohol from an ester product mixture by a gas stripping. The method involves the feeding of the ester product mixture into proximity of an axis of a rotating packed bed, so as to enable the ester product mixture to flow radially to come in contact with a gas which is introduced into the rotating packed bed. The unreacted alcohol and any other volatile component of low molecular weight are thus stripped from the ester product mixture by the gas entrainment, thereby resulting in production of a purified ester product which is collected at the bottom of the rotating packed bed. The unreacted alcohol and the volatile component, which are entrained in the gas, are discharged via an exit located at the top of the rotating packed bed.
