Title: Process for manufacturing a porous gas-flushing brick for metallurgical vessels
Inventor: BURBACH WERNER
IPC: C22B9/05
Filed: 1986-08-02
Granted: 1993-06-15
Abstract: During the assembly of a gas circulation block, encased in sheet metal, a conical sheet-metal sleeve is placed onto a shaped block which is in the form of a truncated cone and made of a refractory material, then a sheet-metal cover provided with a gas supply tube is laid onto the larger end face of the shaped block and then the sheet-metal sleeve is welded onto the sheet-metal cover. In order to reduce the assembly effort and at the same time to create an improved gas circulation block, the conical sheet-metal sleeve is heated up before placing onto the shaped block and is then shrunk onto the shaped block. By the shrinking of the sleeve, every type of dimensional inaccuracy is compensated for, whether on the shaped block or on the sheet-metal sleeve, so that the sheet-metal sleeve, in the shrunk-on condition, sits uniformly and tightly against the shaped block over its entire periphery and its entire length.

Abstract: 강박판 적층 개스킷은 실린더블록과 실린더헤드 사이에 설치된다. 실린더블록에는 개스킷의 위치를 정하기 위해 적어도 두개의 다월이 마련돼 있다. 
     개스킷은 제1판, 제2판, 제3판으로 이루어져 있다. 제1판은 다월에 대응하는 부위에 형성된 제1 및 제2구멍과, 그리고 슬릿들에 의해 에워싸인 적어도 하나의 플랩을 포함한다. 플랩은 제1구멍 인접에 그 안으로 약간 돌출하여 형성된다. 제2판은 제1판 위로 놓여져서 그에 접속된다. 제2판은 제1 및 제2의 구멍에 대응하는 제3 및 제4의 구멍과, 그리고 플랩 위에 위치된 적어도 하나의 홈을 포함한다. 
     개스킷이 다월에 끼워질 때 플랩은, 개스킷이 엔진 블록에 확실하게 접속하도록, 굴곡하여 다월을 맞문다.

Abstract: 본 발명은 비디오 카메라의 윤곽보정장치에 관한 것으로, 종래에는 감마 보정된 신호로부터 휘도처리계에서 수평, 수직 윤곽 보정후 이를 합산하여 윤곽억압부에서 휘도신호에 따라 고휘도 성분을 억압함으로써, 윤곽 보정을 행하는데, 이는 휘도성분에 따라 윤곽 보정이 일정하기 때문에 사람의 얼굴 등을 줌업했을 때 너무 섬세하게 나타나 추하게 보이는 경우가 있다. 
     본 발명은 이를 개선하고자 칼라처리계에서 검출되는 R-Y 색차신호를 버퍼를 통해 추출한 후 이득제어부를 통해 레벨 조절하여 상기 윤곽억압부의 윤곽 보정을 제어하도록 하여 사람의 얼굴 등을 윤곽 보정시에 그 윤곽 보정을 적게 함으로써 부드러운 얼굴화면을 얻기 위한 것이다.

Abstract: An electrode (12) includes a first electrode (12a) having relatively low resistance and a second electrode (12b) having relatively high resistance. The first electrode (12a) is heated first because of its low resistance, then the second electrode (12b) is heated when the resistance of the first electrode (12a) exceeds the value of the resistance of the second electrode (12b). This keeps the temperature inside the tube (11) constant.

Abstract: 자동 분리된 DMOST로 접적화될 수 있는 회로는 DMOST 드레인 금속화층으로 부터 형성된 감지용 레지스터에 의해 구동된다.  상기 회로는 DMOST 전류에 비례하는 출력 전류를 발생시키는데, 상기 비율은 단일의 레지스터의 저항값에 의해 결정된다. DMOST가 소오스전류를 도통시킬 경우에 출력 전류가 발생되며, DMOST의 분로 다이오드가 도통할 경우에 출력전류가 싱크된다. 따라서, 상기 회로는 DMOST 전류와 비례된 출력을 발생시킬 뿐만아니라 DMOST 도통의 모드를 구별한다.

Abstract: Alkenyl  cephalosporin  derivs.  of  formula  (I)  and  their pharmaceutical salts are new. 3-cephem compds.  were  obtained  by witting reaction from a phosphonium cpd. of formula (II)  with  an aldehyde cpd. of formula (III) and then were deacylated to produce 7- amino-3-cephem derivs. The formula (I)  derivs.  are  prepd.  by acylation       of       7-amino-3-cephem       derivs        with 2- aminothiazolyl-2-hydroxyimino- acetic acid compds. In (I),  R1=H or a protecting gp. as  in  cephalosporin  and  penicillin  cpds.; R2=H, C1-4 alkyl or substd. alkyl; R3=H or a deriv. of  a  carboxy gp., an atom for prepn. of a salt or carboxy protecting gp.
