Title: Three-phase AC motor shaft position (angle) estimating method
Inventor: LIOU TIAN-HUA
IPC: H02K24/00
Filed: 2000-04-18
Granted: 2002-04-11
Abstract: There is provided a three-phase AC motor shaft position (angle) estimating method. By using the switching status of the frequency converter, it is able to estimate the counter-electromotive force of the motor, and further determine the current variation rate at the stator side of the motor, thereby achieving the purpose of estimating the AC motor shaft position (angle). Because the AC motor only has a difference in alternative and direct axis reluctance, the motor stator current will generate different current variation rates when the frequency converter is driven. Therefore, it is proved that a precise motor shaft angle estimated value can be obtained from proper calculation by only measuring and calculating the stator current variation rate, which is a function of shaft angle.

Filed: 2000-07-13
Granted: 2005-05-11
Abstract: The present invention provides a heat polishing process and a heat polishing device for slit-down-draw sheet forming. The process is characterized in providing a polished face heating box to the liquid glass after slit-down-draw operation in a continuous process in order to prolong the time when the glass surface is in a liquid state. In the invented process, a polished face heating box is added between the glass nozzle and the glass annealing homogenization box. The polished face heating temperature box can add an additional heating step to the liquid glass slit-down-drawn from the glass nozzle in order to prolong the heating time. Thus, the surface tension of the liquid glass film after the heating step has a sufficient period of time to form a smoother glass surface under that high temperature environment.

Title: Manufacturing process and product for chip-type inductor
Inventor: LEE JONG-MAN
IPC: H01F41/00
Filed: 2001-04-17
Granted: 2002-08-11
Abstract: A chip-type inductor in the present invention provides a manufacturing process and product with characteristics of preventing the inductor from the oxidation, and with quality of easier bending and of less heat damages than those of other processes and products. To achieve the above purposes, the present invention forms an insertion cavity of the inductor that can insert an inductor to a side of a lead frame in the direction of abscissa. Thereof, the present invention forms a protrusion portion in the inner side of the insertion cavity to enhance the strength of the lead frame, and an inner hollow portion in the inner side of the insertion cavity to assemble the lead frame and the inductor easily. Laser irradiation to the contact point of the lead frame and lead wire of the inductor melts together a soldered layer and an Sn/Pb plated layer to solder without oversupplying solder. In the above statement, a lead wire and a cupper wire produce the soldered layer, and the surface layer of the lead frame is the Sn/Pb plated layer. Laser irradiation bonding the protrusion portion of the lead frame to a contact point of the lead wire of the inductor, melts the solder layer of the lead wire and the Sn/Pb plated layer of the lead frame in a short period to prevent the solder from the oxidation. In addition, the amount of the soldering material stained in the lead frame is constant to prevent the solder from flowing down to the lead plate. Even though the melted solder flows down in the case that a manufacturing process supplies the assembly part of the lead frame from the lower direction, the melted solder does not stain the bending portion of the lead frame. Therefore, a bending process of the lead frame is easier than other bending processes. Moreover, the irradiating portion by laser is so small that heat damage to the other part of the lead frame can be less than that in other processes.
