Abstract: DRAM 디바이스는, 외부 C/A 버스, 조정기, 및 내부 C/A 버스를 통해 기록 명령을 수신하면, 기록 플래그의 대기 상태로 진입한다.     기록 플래그 신호선을 통해 메모리 제어기로부터 기록 플래그를 수신하면, DRAM 디바이스는 기록 플래그를 카운트 개시점으로 이용하여 소정 클록수를 카운팅하기 시작한다.     DRAM 디바이스는 소정 클록수가 카운팅된 시점을, DQ 버스를 통해 전파된 기록 데이터를 취입하는 기록 데이터의 취입 개시점으로 이용한다.     기록 플래그의 전달 경로는 기록 데이터의 전달 경로와 동일 토폴로지를 갖는다.     2 개 전달 경로의 전파 지연이 동일하다고 생각할 수 있다.     취입 개시점에 대한 상기 규정에 의해, DRAM 디바이스는 전파 지연에 관계없이 기록 데이터를 적절히 취입할 수 있다.

Abstract: An ink tank of the foam type which is provided with a detected portion capable of exactly and surely detecting the amount of ink used by the printer or remaining in the ink tank. The ink tank includes a sub ink chamber that is diposed or formed between a main ink chamber and an ink outlet of an ink tank of a foam type. When an amount of air flowing into the sub ink chamber increases, one or more reflecting surfaces of a right-angled prism, which function as ink interfaces, resume their original function of reflecting surfaces, thereby enabling the detection of an ink end. Air bubbles having entered the sub ink chamber are surely led onto the one or more reflecting surfaces by a bubble storage part. At an ink passage having a narrow width, which is defined by the one or more reflecting surfaces, air bubbles are pressed against the one or more reflecting surfaces to be put to a crushed state and in surface contact with the latter. Air bubbles are surely led onto the one or more reflecting surfaces, and are crushed and pressed against the reflecting surfaces. This configuration prevents the one or more reflecting surfaces from being covered with ink retained in spaces among the air bubbles. Therefore, the ink end can be detected surely and exactly. <IMAGE>   <IMAGE>
