Title: Method for backing up charging data into sub file unit in mobile switching center
Inventor: JEON JOON KIL
IPC: H04M15/00
Filed: 1998-12-31
Abstract: PURPOSE: A method for backing up charging data into a sub file unit in the mobile switching center is provided to prevent the loss of charging data by backing up charging data, in case that charging data cannot be transferred to a billing center or a magnetic tape. CONSTITUTION: If an operator inputs an instruction to back up charging data to a charging backup magnetic tape using a local terminal, an MMP(Man Machine Processor), receiving the instruction, outputs a signal to execute the instruction(S100). If a CHIM(Charging Information Management), receiving the number and quantity of sub files, outputs a signal to request function execution(S200), a CDR(Charging Data Recording) calculates the location of sub files and reads the charging data in a charging disk(S300). The CDR records the charging data in a backup magnetic tape(S400) and outputs a result signal for instruction execution(S500). The MMP outputs a message for the instruction execution result to the local terminal(S600).

Filed: 1998-12-31
Abstract: PURPOSE: A pipe bending machine is provided to increase the working efficiency by automating a serial operating process from a supply of a pipe to a bending and a ventilation and to embody a bending toward multi-directions with one process. CONSTITUTION: After one end of a pipe is inputted from a transferring device of pipe into a chuck unit(311), air or a fluid is flowed in a cylinder and pushes a cylinder piston(312). The pipe inputted in the one end of the chuck unit is firmly held during moving the chuck unit inside a collet housing. In a state that a clamp(422) compresses the pipe in a jig(414) direction by a cylinder, a bending clamp(420) is rotated to interlock a rotary cylinder(410) in a rotating shaft during operating. The pipe expressed in a virtual line is bent at first. A change of the pipe is prevented by holding the one end of the pipe with a supporting clamp(431) during sliding. The supporting clamp is restored after bending through a upper spring(432).

Abstract: 본 발명은 외과 수술시 조직의 유착을 방지하기 위해 수술부위에 부착하는 유착방지제 및 그것을 구성하는 부직포의 제조방법에 관한 것으로 유착방지기능을 개선하고,경제적으로 유착방지제를 제조할 목적으로 안출된 것이다. 
     이를 위하여 본 발명은 생체분해성 재생셀룰로오스 부직포에 유착방지수단을 포함시킨 유착방지포(1)와 생체분해성 재생셀룰로오스 부직포에 지혈수단을 포함시킨 지혈포(2)를  생체분해성 접착제(3)으로 부착하여 일체로 구성한 것을 특징으로 하는 외과수술용 유착방지제와, 재생셀룰로오스를 MMNO 용매에 용해하여 이 용액을 방사구(4)를 통하여 토출시킨 후에  용매가 부착된  섬유를 roller 또는  conveyer belt에 의한 집속기(5)로 집속할 때 집속장치에 10∼100kV 범위의 고전압을 걸어 섬유를 가늘고 균일하게 분산시키는 방법의 부직포제조방법을 제시한다.

Abstract: PURPOSE: A method for measuring a focus of an exposure equipment using a pattern for measuring the focus of the exposure equipment as a mask is provided to improve repeatability and reliability of a measurement and to greatly reduce the time necessary for the measurement, by automatically measuring the focus of the exposure equipment using an overlay measuring apparatus. CONSTITUTION: A semiconductor substrate on which a photoresist layer is formed by using a pattern for measuring a focus of an exposure equipment as a mask, is formed. The position of a photoresist layer pattern is measured by using an overlay measuring apparatus in a predetermined scope of the photoresist layer pattern formed on the semiconductor substrate in an exposure process.
