Title: fixed apparatus of chuck for numerical control machine
Inventor: CHO GEUN JE
IPC: B23Q1/70
Filed: 2000-03-20
Abstract: PURPOSE: A chuck fixing device of a machine tool is provided to easily replace and fix a chuck by firmly mounting a chuck on a spindle without bolting. CONSTITUTION: A chuck fixing device for a machine tool has a first collector(104) having many fixing clutches while being combined to the lower portion of a transfer hole(105) of a spindle(102), a first collector combining unit for combining the first collector to the lower portion of the transfer hole, a fixing member(107) radially formed on the upper face of a chuck(101) while having a first ledge(106) in the upper inner end, a cubic coupling(126) having irregularities to transmit the rotational force of the spindle to the chuck, and a fixing clutch holding unit for holding a hanging part of the fixing member with the fixing clutches of the first collector. If a transfer rod(121) descends by a hydraulic cylinder(123), an inclined face(120) of the transfer rod is inserted into the first collector and the fixing clutch widens outwardly. The fixing clutch contacts with the neighboring fixing clutch by an elastic ring(115). Thus, separation of the first collector from a first combining groove(114) is prevented. After the chuck is fixed by the first collector, the rotational force of the spindle is transmitted to the chuck as the spindle is engaged with the chuck via the cubic coupling. For separating the chuck from the spindle, the transfer rod is lifted up to narrow the fixing clutch of the first collector. Then, the fixing member is disassembled by the separation of the ledge from the fixing clutch. Therefore, the chuck is fixed and disassembled easily. Further, work efficiently is improved.

Title: correlation-aided distributed sample acquisition method, and apparatus for the same
Inventor: KIM BYEONG HUN
IPC: H04B1/708
Filed: 2000-03-24
Abstract: PURPOSE: A method for a correlation auxiliary DSA(Distributed Sample Acquisition) and an apparatus thereof are provided to rapidly acquire a long period of scrambling sequence used in WCDMA(Wideband Code Division Multiple Access) system in the very poor environment by having a synchronization based on the comparison-correction and a correlation for a state symbol. CONSTITUTION: A sample inverse diffusion unit(30) acquires a lighter sequence used to spread in a base station, diffuses a state signal received in the lighter sequence to detect a pilot signal, decodes the pilot signal by using differential PSK(Phase Shift Keying), and outputs a soft decision state symbol. A state symbol storage(60) stores the soft decision state symbol. A cell/frame boundary searching unit(70) correlates the soft decision state symbol. A symbol demapping unit(36) sequentially demaps the sate symbol to each state sample. A parallel comparing unit(41) compares the state samples, which have been obtained by sampling each state of one or more sequence generators sampled, with each state sample output from the symbol demapping unit(36). A parallel correcting unit(42) repeatedly corrects states of the sequence generators in response to the result of comparing.

Abstract: PURPOSE: A substrate connector of a flyback transformer focus pack and a breeder resistor is provided to form focus and screen resistor patterns and a breeder resistor pattern on one substrate to construct a compact focus pack. CONSTITUTION: A breeder resistor pattern(160) is printed between focus and screen resistor patterns(120,130) formed on a substrate of a focus pack(100) so that the focus and screen resistor patterns and the breeder resistor pattern are integrally connected with each other. An insulating resin impregnation part is formed at the breeder resistor pattern to insulate the breeder resistor pattern. An insulating resin(E) is put into the impregnation part to be hardened.
