Title: Dual mode ink jet printer
Inventor: FISCHBECK KENNETH H
IPC: H04N1/04
Filed: 1989-08-25
Granted: 1993-04-09
Abstract: In the embodiments of the invention described in the specification, a four-color ink jet printer includes a transport mechanism for conveying a record medium in one direction and an ink jet head containing a black ink nozzle array and a primary color ink nozzle array for scanning the record medium in a transverse direction while projecting drops of ink onto the record medium. A control unit provides two printing speeds in which either high-quality or high-speed printing can be accomplished. For high-speed printing all of the nozzles of both arrays are used, and for high-quality printing one-third of the nozzles in the black ink array and all of the nozzles in the primary color ink nozzle array are used and the record medium is transported at one-third the rate used for high-speed printing. In certain embodiments, the two arrays of nozzles are disposed at different angles with respect to the scanning motion of the ink jet head so that the nozzles of the primary color array are spaced in the direction of motion of the record medium by a greater distance than the nozzles of the black ink array. In other embodiments, the arrays are disposed at the same angle with respect to the scanning motion and the nozzles for the three primary colors may be alternated in the color nozzle array.

Title: Locator for expendable core in die casting die
Inventor: KOCH BYRON W
IPC: B22D17/22
Filed: 1990-09-21
Granted: 1999-01-15
Abstract: The locating pins have notched ends, each of which simultaneously restricts the movement of an expendable core in two orthogonal directions in a die casting die. A plurality of these pins alone and with other pins project into the space between the printout cavity in a die casting die and the printout portion of an expendable core positioned in that cavity. Other pins having flat ends locate the core in only one directional line. Still other pins having tapered ends require special pockets in the printout section of the core, which pockets have sides that must be formed adjacent to the tapered surfaces of these pins. The configurations of the space around the printout portions of the cores permit molten metal injected into the die to produce a skin or skull over the printout portions, which skin can have thicker ribs or portions through it for further reinforcing the printout portions. These printout portions on the parting line between two dies may have restrictions at the junction of the printout portion with the main portion of the core to form break-off rings. These rings and ribs may be formed either in the die or in the printout portion of the core, or both.

Abstract: The method includes the steps of applying a chemical-amplified positive photoresist (2) of 1.0 micro m thickness on a silicon wafer (3), exposing the wafer using a mask (1) and an excimer laser, baking the wafer for one minute at 60 deg.C., acid-treating the photoresist layer using an acetic acid solution for 1.5 minutes to change the resist layer portion of 600 angstrome into a soluble layer (5), and developing the wafer to obtain a line pattern, thereby forming micropatterns of exact sizes.

Title: Lan communication with 2-stage transmission procedure
Inventor: LEE SUN-HOON
IPC: H04L12/28
Filed: 1992-12-29
Granted: 1996-10-10
Abstract: The device includes a transmission counting means(6) for generating a transmitting chance signal, a generating means of frame existence signal(17) for judging and generating the signal in the case of existence of transmitting frame, a generating means of frame existence signal(18) for judging and generating the signal in the case of non-existence of transmitting frame, and a frame transmitting means(19). The method comprises the steps of; performing a frame transmitting procedure continuously, performing a stop of operation of transmitting counter, generating a transmitting signal, and transmitting a frame through a common bus.

Title: A process and a processing die of soybean protein food
Inventor: LEE JIN-HUI
IPC: A23L11/00
Filed: 1992-12-30
Granted: 1995-08-16
Abstract: The soybean protein food is prepd.  by 1) supplying soybean  protein isolate  contg.  20 wt%  or  less  fat-removed soy  protein  and  4˜55% water into  a twin-screw  extruder, and  2) extruding it through a long popping  die.  The  die  comprises a plunge(7), a  right-angled hexahedral die(8) having a pathway in the center of the plunge(7), a slit length  control  unit(10)  having  a  control  nut(9)  for  slit  length  and bolt(9').

Abstract: 본 발명은  점도가 높은 회수오일등이나 크게 성장한 스컴이라 하더라도 회수해서 분리할 수 있게 하는 것을 목적으로 하는 것으로서, 그 구성에 있어서는, 본체플로우트에 의해서 액체에 뜨는 본체조와, 본체조의 외주에 헐겁게 끼워져서 가이드플로우트에 의해서 액체에 뜨고 구배면을 가지며 본체조내에 액체를 도입하는 유입언과, 본체조내의 액체를 배출하는 배출부로 이루어지고, 유입언의 구배면상에 긁어모으는 기계를 설치하고 또한 본체조내에 압입스크류를 설치하므로서, 구배면상의 부유물을 긁어모아 본체조내에 압입한다. 그리고, 또 발명은, 회수펌프에 의해서 회수오일등을 사이클론부에 보내어 기액분리하고, 내통과 외통을 동심형상으로 배치하여, 이들의 사이에 스파이럴형상벽을 형성한 비중차분리부에 회수오일등을 공급해서 비중차가 있는 액체를 분리하고, 저류빼내기부에서 비중이 가벼운 액체를 저류 또한 외부에 배출하고 내통내에 배출관을 접속한 오우버플로우부에서 비중이 무거운 액체를 외부에 배출하므로서, 공기, 오일, 물의 3성분을 분리 회수하는 것을 특징으로 한다.
