The transitional portion defines four straight edges, each meeting a different one of said edges defined by the wedging portion, and each being inclined at a lesser angle relative to the same axis. The wedging portion has a plurality of convex surfaces, each conforming generally to a section of a circular cylinder. The transitional portion has a plurality of convex surfaces, each conforming generally to a section of a circular cylinder. A cutting tip is formed as a thin rib extended across the penetrating portion. A pair of thin cutting ribs extended from the cutting tip are formed along the wedging and transitional portions.

Granted: 1992-07-20
Abstract: The microwave oven includes a cooking  chamber  (6)  provided with a rotatable tray (2) for placing articles  to  be  cooked.  A rotation member  (4)  includes  pairs  of  arms,  each  having  a relatively longer length  arm  extending  inone  direction  and  a relatively shorter length arm extending in an opposite  direction. For supporting the  tray,  relatively  larger  members  are  fixed rotatably to the relatively shorter arms  and  relatively  smaller members  rotatably  fixed  to  the  relatively  longer  arms.  The rotation member is guided so that it is moved  in  slant  along  a predetermined path formed on the bottom of  the  cooking  chamber. The incidence angles of microwaves to articles to be cooked can be varied according to the inclined angles of  the  tray  during  its rotation.  The  microwave  oven  provides   equal   dispersal   of microwaves over foodstuffs on the rotatable tray.

Abstract: In the method of generating a sampling clock with a predetermined cycle in order to obtain a test data in a ultrasonic testing system, the method of generating a sampling clock of a ultrasonic examination system comprises the steps of: storing a combination of enabling correction values storing the upper addresses that indicates the storage position of each correction combination value stored, and a base value for each scan line; reading out the corresponding base value for each scan line and the upper address as the combination of the correction values; reading out the correction value corresponding to the upper address; and counting a count value obtained from the base value and the correction value.

Title: Air injecting device of cell cultivator
Inventor: LEE HYON-YONG
IPC: C12M1/04
Filed: 1993-01-08
Granted: 1995-07-13
Abstract: The air supplying device for a cell cultivation consists of winding silicon tube (8), an supports (8,8') and an air supply tube (5). Air is supplied from the hole (4) of the rotor (3) to pass through (4) and bubble through (5). The CO2 gas generated during animal cell cultivation (I) is captured by (8) and passed through the outlet (6). This device prevents oxygen gradient in the broth and serves less shear stress to (I).

Title: 개폐식 전기 콘센트와 같은 전기장치용 하우징
IPC: H02B1/28
Filed: 1993-04-06
Granted: 2001-01-15
Abstract: 본 발명은 측벽 및 단부벽들을 갖는 전기적 비전도성 포위체를 지니는 전기하우징 장치에 관한 것이다. 단부벽들중 전기적 도관을 수용하는 구멍을 지니며 다른 벽들은 비관통형이다. 전기적 도전성 프레임이 포위체 내부에 장착되며, 전기 장치들을 지지하도록 배치된 프레임은 특정하게 수직으로 배향되며 도관과 하우징내의 전기 장치사이에 접지 접합을 제공한다. 프레임의 양단부의 장착용 브래킷은 구멍들을 지니는바, 그 구멍들중 하나는 프레임이 포위체내에 배치될 때 단부벽 구멍에 정렬될 수 있는바, 이는 포위체의 방향에 따라 결정되며, 구멍을 갖는 단부벽은 상부에서 상부 도관 연결을 허용하며 하부에서 하부 도관 연결을 허용한다. 방수 덮개가 박스의 전방을 밀폐하며, 덮개와 프레임은 사용되는 포위체의 방향에 관계없이 단일 방향으로 정렬된다.
