A simulation method has been purposed in this paper to optimize the stack structure of metal/ITO cathode for full transparent or top emission devices. The result demonstrates that the complexity of the two proper layers thicknesses design is reduced. Finally, the experiment data also strain the simulation result.

The control of stator flux, torque angle, excitation torque, reluctance torque and total torque of the direct torque control (DTC) for a permanent magnet synchronous motor (PMSM) are studied in this paper. Simplified expressions to represent the changes of these variables due to the application of a voltage vector are given. Finally, a voltage vector selection area and the implementation of a voltage vector selection strategy are proposed.

Objectives & Methods : This study was to study etiology and pathologic mechanism and to study acupuncture and moxibustion treatment for GU-CHANG. I've got compared and analyzed 42 kinds of book since Nei Jing(內經). Results and Conclusion : 1. The etiologies are heat of heart and spleen, insufficiency of middle -warm energy, deficiency of yin lead to hyperactivity of fire. 2. The meridians of acupuncture points which were used much for GU-CHANG were Conception Vessel Meridian, Stomach Meridian and Bladder Meridian. 3. The frequency of using acupunture points in this treatment were Hapkok(LI4)-17th, Sungjang(CV24)-14th, Nogung(P8)-12th, Kumjin Okaeg(NH70)-11th.

The pressure-area isotherm(${\pi}$-A isotherm) of 8A5H(4-octyl-4'-(5-Carboxyl-pentamethyleneoxy)-azobenzene) at the air/water interface were obtained. Using the Xe/Hg Xe 500w(93' model 68811), an activities of molecule at the air/water interface were certified. In addition, using a current-measuring technique, we investigated the abrupt changes of a current observed at the liquid-to-solid phase transition in a current-area (I-A) isotherm of a fatty acid monolayer at the air/water interface

In this paper, optimum shape design of permanent magnet in slotted type Permanent Magnet Linear Synchronous Motor(PMLSM) is progressed for minimization of detent force owing to structure of slot-teeth and thrust ripple by harmonic magnetic flux of permanent magnet. The characteristics of thrust and detent force computed by Finite element Analysis are acquired equal effect both skewed basic model and optimum model which is optimization of permanent magnet shape.

This paper present dynamic stiffness of servo motor using labVIEW PXI module. In speed control loop, we apply proportional gain and integral gain, using PID controller, respectively in servo motor and confirmed dynamic stiffness of servo motor varing each gain. Changing proportional gain and integral gain, confirm what effect in dynamic stiffness are change in frequency response..

This paper is deal with the method of redesign for optimum thrust model using Neural-Networks in Permanent Magnet Linear Synchrous Motor(PMLSM). This method is saved time compared with design method using only Finite Element Method(FEM). In this paper data sets for training Neural-Networks obtained using 2D FEM. To confirm the validity of the data sets for training Neural-Networks optimum values of that Is compared with results of FEM. And then. this method is verified that it could be applied to the design for Slotless type PMLSM.

This report describes the adhesibility of the polyurea greases. Generally, Polyurea greases were divided into three classes, aliphatic, alicyclic, and aromatic, according to the differences of the terminal alkyl group. The adhesion properties of polyurea greases were tested with Adhesion Tester by In-house method.

Four Humboldt penguins were imported from overseas in March, 1975. Soon after arrival at the Zoological Garden of Chang Gyeong Won in Seoul, two penguins became ill with symptoms of severe dysnnoea, vomiting, diarrhea and mild convulsion. They died on the second day of illness. The main pathological finding was bronchitis which accompanied a caseous airsacculitis on the left lung. A massive melanin pigmentation in the intertubular tissue of the testis was found accidentally.
