Title: Speed control method and apparatus for synchronous reluctance motor
Inventor: LEE DONG MYEONG
IPC: H02P6/06
Filed: 1998-12-31
Abstract: PURPOSE: A speed control method and a controller are provided to control the speed of a synchronous reluctance motor by using the reference voltage magnitude and phase modified in a field weakening region and a positive torque region. CONSTITUTION: A speed detector(108) connected to a synchronous reluctance motor(100) detects the motor speed and feeds back it to a speed controller(200). The speed controller compares the feedback signal with a reference speed(115). If these two speeds are not equal, then the controller determines whether the control region is at a field weakening region or at a positive torque region and provides the modified reference voltage magnitude and phase. In a field weakening region, if the motor speed is greater than the reference value, then the controller decreases the reference voltage phase, or increases it otherwise. In a positive torque region, if the motor speed is greater than the reference value, then the controller decreases the reference voltage magnitude, or increases it otherwise. A reference voltage generator(201) produces a field voltage and a torque voltage based on the modified signals. A voltage generator(114) produces the 3-phase voltage with the output of the reference voltage generator and an inverter(101) applies the voltage to a synchronous reluctance motor.

Abstract: The present invention relates to cartilage extracts and to a method of producing the same. Shark cartilage extracts having anti-angiogenic, direct anti-tumor proliferating, anti-inflammatory and anti-collagenolytic activities have been obtained by an improved process. The process comprises the steps of obtaining a homogenate of cartilage in an aqueous solution, this homogenate being centrifuged and further fractionated to obtain a total extract having molecules of a molecular weight comprised between 0 to 500 KDa. The composition of the liquid extract has then been investigated by different ways. Further fractionation of this extract led to the preliminary characterization of some of its active components. Due to the multiplicity of biological activities of the total liquid extract, it can be used for treating numerous diseases or conditions such as those having components selected from the group consisting of tumor proliferation, angiogenesis, inflammation and collagenolysis. This extract has no offensive effect on normal body functions. Therefore, this shark cartilage extract has a very promising therapeutic value. The process for the obtention of cartilage extracts is simple and efficient. The unexpectedly valuable products obtained by this process are therefore an indication of a new and non-obvious process.

Abstract: PURPOSE: A suspension system for a vehicle is provided to simplify the structure as keeping vibration absorption and rolling reduction of a suspension system for a vehicle. CONSTITUTION: A lower arm rotates by bounding of a tire caused by an irregular road surface during driving a vehicle. Thereby, a first torsion bar(4) is distorted and a strain gauge checks the distortion. A clutch(13) is turned off not to deliver the torsion stress of the first torsion bar(4) to a first reducing member(5) if the distortion is lower than a specific degree. Otherwise, the torsion stress is delivered to the first reducing member(5) and a fluid(2) filled in a reducing housing(3) rubs with the rotating first reducing member(5). The torsion stress delivered to the first torsion bar(4) is reduced by the friction between the fluid(2) and the first reducing member(5). The rotational speed of the first reducing member(5) decreases even in reverse rotation to inhibit free vibration.
