Title: 광자기 기록 매체
IPC: G11B11/105
Filed: 1998-07-15
Abstract: 광자기 기록 매체는, 실온에서 면내 자화 상태(面內 磁化 狀態)이고 온도 상승에 따라 수직 자화 상태가 되는 재생층, 제1 차단층 및 수직 자화막으로 이루어지는 기록층을 구비하고 있다.  제2 차단층은, 재생에 관한 기록 비트 이외의 기록 비트의 자화가 재생층에 있어서의 신호 재생 영역에 전사되는 것을 막기 위한 것이다.  이 때문에, 기록층에서의 기록 비트를 고밀도로 하더라도, 재생층에는 재생에 관한 기록 비트의 자화만이 전사되도록 되어 있다.  따라서, 이 광자기 기록 매체를 이용하면, 기록층에 고밀도로 기록 비트를 형성하더라도, 양호한 재생 신호를 생성할 수 있게 된다.

After OMP confirms the script completion message(219), it checks whether MMP has received the clause inspection signal and starts Request Sense(221). If not, the system checks for BUSY state and if busy, OMP returns the word E_Busy. When the script is completed OMP launches ChkfltREC(229), checks whether SCSI bus is busy(231), if busy the Watchdog timer is stopped(233) and reset(235). Then, it checks if the initiated program is a magnetic tape program, and if yes OMP proceeds, but if no the operation that was reset is restarted(239).

Abstract: 본 발명은 에틸렌계 불포화물을 함유하는 유기 화합물의 니트릴로의 시안화수소화, 특히 디올레핀 또는 치환된 올레핀, 예컨대 알켄니트릴의 시안화수소화의 방법에 관한 것이다. 
     더욱 구체적으로, 본 발명은 적어도 하나의 전이 금속 화합물 그리고 적어도 하나의 수용성 포스핀을 함유하는 촉매의 수용액의 존재에서 시안화 수소와의 반응으로 적어도 하나의 에틸렌계 이중 결합을 포함하는 유기 화합물의 시안화수소화의 방법에 관한 것인데,  상기 수용성 포스핀이 모노덴데이트 또는 비덴테이트 포스핀인 것을 특징으로 한다.

Abstract: An aluminum alloy containing (in wt. %): 0.2-0.5 Fe; 0.7-1.2 Si; 1.2-1.6 Mn; up to 0.3 Mg; up to 0.5 Cu; up to 0.2 Zn; up to 0.1 Ti is used to make the fins of heat exchangers particularly car radiators. The finstock has high post braze strength and thermal conductivity, and has a sufficiently electronegative potential as to be capable of acting as a sacrificial anode for the heat exchanger tubes. By virtue of the absence of Sn, In, and Cr, these heat exchangers can be scrapped and melted for re-use.
