Title: Single-chip microcomputer
Inventor: WAKIMOTO YATSUHIRO
IPC: G06F21/86
Filed: 1984-09-19
Granted: 1989-04-29
Abstract: This system inhibits switching to mode using an internal memory and an external memory when program counter indicates address is not in the internal memory.  A port interfaces the external ADD-ON ROM to the single-chip microcomputer.  The available memory region includes addresses in the internal ROM and in ADD-ON ROM.  The addresses available are only in the ADD-ON memory.  The external access signal is inhibited from being input to the CPU except whilst the reset signal is generated by an inhibiting device.  This is to avoid the internal program instructions being read into the ADD-ON memory.

The requested condition of kaolin particle is as follows; 0.4<=DA<=0.8, 0.5<=DB/DA<=1, 0.10<=WA<=0.20, 0.5<=WB/WA<=1.0, 0.4αA, 1.79 βA/DA<=5.77. DA and DB is average particle size ( m), and WA and WB is weight percentage of kaolin based on polyester.

Title: Forming mehtod of cvd tungsten film
Inventor: PARK SON-HU
IPC: H01L21/28

Granted: 1994-12-23
Abstract: The method for burying the contact hole formed in the insulating film (3) on the semiconductor substrate (1), includes the steps of depositing a thin tungsten film (4) on the inner side of contact hole by using the H2 reduction reaction and depositing a tungsten film (5) on the film (4) by using the SiH4 reduction reaction. The H2 reduction is processed at the temp. of 200-300 deg.C under condition of, the H2 flow of 500-1000 SCCM, the WF6 flow of 2-6 SCCM, and the reactor pressure of 50-100 mtorr. The SiH4 reduction is processed at the temp. of 200-300 deg.C under condition of the H2 flows of 100 SCCM, the SiH4 flow of 10 SCCM, the WF6 flow of 20 SCCM, and the reactor pressure of 100 mtorr. The method improves the adhesion characteristic and prevents the degradation of the electric properties to reduce the Si loss.

Title: 사판식 압축기
IPC: F04B27/14

Granted: 1999-06-15
Abstract: 가변이동기구를 구비한 경사판형 압축기가 개시되어 있다. 압축기는 압축기 하우징에 회전가능하게 지지된 구동축과 구동축의 회전운동이 피스톤의 왕복운동으로 전환되도록 구동축을 피스톤과 구동연결하는 연걸기구를 포함하는 구동기구를 구비한다. 연결기구는 경사면을 가지는 경사판을 구비한다. 경사각은 압축기의 용량을 변화시키기 위하여 크랭크실내의 압력의 변화에 따라 변화한다. 구동축은 구동축의 다른 부분의 직경보다 작은 직경을 가지는 내단부를 구비한다. 경사판과 실린더 블록 사이의 구동축의 내단부위에는 경사각이 정해진 각 이하로 감소된 때 여러 경사각 사이에서 경사판의 자유로운 피봇운동이 방해됨이 없이 경사판이 최대경사각으로 복귀할 수 있도록 구동축의 다른 부분의 직경보다 더 큰 외경을 가지는 바이어스 스프링이 탄성적으로 설치된다. 따라서, 압축기의 재가동이 개시된때 압축기의 내부 구성부품위에 작용하는 충격력이 감소되며, 경사각이 정해진 각 이하로 감소하는 때 바이어스 스프링은 최대 경사각을 향하여 충분히 경사판을 가압할 수 있다.

Title: Gloss efficiency increasing apparatus by polarized light
Inventor: KO HAN-IL
IPC: H04N5/74
Filed: 1991-12-27
Granted: 1995-05-18
Abstract: The light efficiency increasing device is structured in a manner that a reflection mirror is installed on the polarized light mirror to reflect a transmitting light which transmits through the polarized light mirror installed in the polarized light transformer; the transmission light which is re-transmitted through the polarized light mirror after being reflected from the reflection mirror, is transformed into a reflection light by an λ/4 plate installed on the bottom of the polarized light mirror and the reflection mirror, and then directly projected by being reflected from the polarized light mirror.
