Abstract: A method that can effectively increase the transesterification conversion of oils comprises the following steps of setting a rotating packed bed reactor for performing centrifugal rotation, centrifugally rotating the rotating packed bed to rotate relative to the container by the drive shaft; heating the oils and additives being heated to arrive at a temperature range approximately between 40 degrees Celsius to 100 degrees Celsius before entering the rotating packed bed; injecting the oils and the additives; performing the transesterification reaction, wherein the oils and the additives are delivered by a centrifugal force to pass through the stainless steel filler in the packed reaction region; performing the transesterification reaction with a rotation speed range of approximately 300 rpm to 1500 rpm; inducing a phase separation; and collecting the effluent at the outlet of the rotating packed bed reactor.

Abstract: For clearly identifying a product recorded in an image file provided by a client terminal, a method for identifying a remote pattern method is provided for preventing disputes between consumers and shopping websites. Such disputes are often caused when a conventional shopping website just searches products required by a consumer based on messages provided by the consumer. In the provided method, an image file of a required product of a consumer is identified by a customer service terminal for generating a plurality of keywords related to the required product. The keywords are then inputted into a database for searching. Detailed information about the required product is found according to search results. After the detailed information is examined by the customer service terminal, the examined detailed information is returned to the client at the client terminal.

Abstract: A combined PLL and ALL module for switching FM signals includes a PLL unit and an ALL unit electrically connected therewith. The PLL unit is used to initially process FM signals received from a co-channel. Outputs of the PLL unit are sent to the ALL unit and processed therein. The PLL unit and the ALL unit are controlled to process the FM signals by adjusting the ratio of second amplitude to first amplitude to closely approach a predetermined value such that the two FM signals are switched.

Abstract: A systolic squarer comprises a systolic array classified into five cell modules by pipeline and regulation according to each operational circuit. According to fundamental structures, the five cell modules constitute the systolic squarer. Each of the cell modules is selected from a group consisting of plural full adders, plural half adders and plural AND gates. Thereby, the five cell modules are suitable for applying to process a great number of digital signals of data, speeding up processing time, and reducing hardware cost and power consumption.

Abstract: A piezoelectric optical micro-switch structure includes a base unit, a first cantilevered arm base, a first piezoelectric controller, a second cantilevered arm base, a second piezoelectric controller and an optical reflector. The base unit bears the first cantilevered arm base and the second cantilevered arm base each of which has a first cantilevered arm and a second cantilevered arm. The first piezoelectric controller and the second piezoelectric controller are correspondingly attached to the first cantilevered arm and the second cantilevered arm and used to control bending angles of the first cantilevered arm and the second cantilevered arm. Connected between the first cantilevered arm and the second cantilevered arm is the optical reflector. When one of the first cantilevered arm and the second cantilevered arm is bent, the optical reflector can change a reflective direction of incident light.

Abstract: An earthquake simulating vibration table includes a vibration machine having a vibration table provided on the topside. Paper models are assembled on a model fundamental base that is fixed on the vibration table. The vibration machine is controlled by a computer to produce simulated various-degree earthquakes. A test of anti-seismic strength of the paper models begins with a smallest seismic strength and then the seismic strength increases by degrees until it reaches to a largest level to have all the paper models collapse. The earthquake simulating vibration table is convenient and quick in assembling, economical in cost and able to be popularized to schools to serve as a course of vibration resistance education to elevate students' learning interest.

Abstract: A multi-functional geometric puzzle system includes four right-angled triangle pieces and two kite-shaped pieces. Each of the right-angled triangle pieces has an identical configuration, and each of the kite-shaped pieces also has an identical configuration. Each of the kite-shaped pieces is formed with four edges, and consists of two side right-angled triangles symmetric along-a longitudinal line. Each dimension of the side right-angled triangles is identical with that of the right-angled triangle piece. In assembling, all of the right-angled triangle pieces and the kite-shaped pieces can be selectively pieced up to generate various geometric patterns.

Abstract: A multi-functional pyramid sphere-puzzle system includes five types of basic sphere pieces. The basic sphere pieces comprise one three-sphere piece and four different four-sphere pieces. The three-sphere piece has a 120-angled array. The first four-sphere piece is arranged in a vaulted array, the second four-sphere piece in a first three-sphere linear array, the third four-sphere piece in a second three-sphere linear array, and the fourth sphere piece in a right-angled array. In puzzle game, the selected types and the desired amount of the sphere pieces can be assembled to form the pyramidal array with various orders.

Abstract: The invention relates to a control method and a control system for a motor. The control method and the control system of the invention transfer the motor dynamic equations of the synchronous d-q frame into a motor parameter (for example, the leakage inductance) and the equivalent counter electromotive force. Then the required control signals for the motor current control can be obtained. The control method of the invention not only preserves the merit of constant switching frequency of the convention PI-PWM control system, but also can eliminate the motor current phase-lag problem of the invention PI-PWM control system. Also, the control method of the invention will have the following characteristics and economic advantages such as high accuracy, fast response, low cost and robustness, etc.
