Abstract: An apparatus and method for regulating the gap between a casting nozzle and a casting wheel in which the gap between the casting nozzle and the casting wheel is monitored by means of at least one sensing element protruding from the face of the casting nozzle. The sensing element is preferably connected to a voltage source and the casting wheel grounded. When the sensing element contacts the casting wheel, an electric circuit is completed. The completion of the circuit can be registered by an indicator, and the presence or absence of a completed circuit indicates the relative position of the casting nozzle to the casting wheel. The relative positions of the casting nozzle and casting wheel can thereby be selectively adjusted to continually maintain a predetermined distance between their adjacent surfaces.

Title: Method for searching record ending point in vedio cassette recorder
Inventor: KOO KWAN-MO
IPC: G11B27/10
Filed: 1990-12-31
Granted: 1998-04-17
Abstract: A searching method of a recording ending point loads a reverse voltage without waiting a natural stop of a motor when the motor stops operating, reduces a running distance passing a stop point, compensates a distance by using only one running, and reduces a time. The searching method performs A/D conversion about a back electromotive force proportional to a rotation speed of motor, samples a motor rotation speed every a constant time from a recording finishing time point, and calculates a distance passing an ending point. If the recording finishing point is detected, the searching method continuously checks a speed value read in the microcomputer, resets a distance data if a sufficient small speed is made; and performing a reverse direction maximum running until a 1/3 distance of a distance from the ending point is prepared.

     부우스터하우징(10)내의 진공챔버(36,38)와 압력챔버(40,42) 사이에 가동벽(20,22)이 배열되며 동력출력부재(68)와 연결된다. 부우스터하우징(10)이 고정된 흙밭이벽(30)을 관통해 뒤쪽으로 뻗어있는 칼라(44)가 부우스터하우징(10)으로부터 축방향으로 돌출된다. 
     칼라(44)내에서 안내된 원통형 슬리이브(52)를 구비한 밸브하우징(50)은 가동벽(20,22)과 연결된다. 작동부재(64)와 함께 축방향으로 이동가능한 밸브동체(60)는 밸브하우징(50)내에서 안내된다. 벨로우즈(90)는 작동부재(64)를 칼라(44)와 기밀하게 연결시키고 방사상의 간격을 두고 슬리이브(52)를 둘러싼다. 슬리이브(52)와 같은 축방향으로 밸브동체(60)로 향하는 주위공기의 흐름경로에 내외측의 환상형 공기필터(88,100)가 잇달아 배열된다. 외측 공기필터(88)는 부우스터하우징(10)의 칼라(44)의 바로 뒤 밸브하우징(50)의 슬리이브(52) 주위 배열되고 고정링(80)에 고정된다. 고정링(80)은 칼라(44)에 고정된 전방 링부분(82)과 벨로우즈(90)를 고정하는 후방 링부분(92)을 포함하며 주위공기의 송입구(86)가 설치된다.
