Title: Method of built-up welding
Inventor: RYU HO-CHON
IPC: B23K9/04
Filed: 1989-12-30
Granted: 1992-04-02
Abstract: The method includes a step of  preparing  a  low  alloy  high tensile strength steel to  use  it  as  a  base  material.  Cracks produced on the base material are gauged, machined, and pre-heated to a temperature of 125-150 degree C. A welding  is  performed  to form an initial layer by using a welding rod which has  a  tensile strength lower than that of the base material, and  has  a  carbon content lower than that of the base material by 50-80%. Then,  the surface of  the  initial  welded  layer  is  machined  until  the oxidation film is removed, and then, a buttering is  performed  on the recess of the initial layer. The rest of the portions  of  the initial layer is further welded, and then, the welded  portion  is subjected to a post heating, thereby completing the whole process.

Title: Recording method and device of information patterns on record carrier
Inventor: BAKS JOHANNES L
IPC: G06F3/06
Filed: 1990-06-23
Granted: 2000-05-01
Abstract: In the method and the device disclosed herein at least one record-carrier-dependent parameter (Is), which influences the quality of the recorded information pattern (58, 59), is adjusted. In determining the optimum setting of the parameters (Is) a calibration area (21) is selected from a number of predetermined calibration areas (21a,..., 21d). The selected calibration area (21) is provided with test patterns for different settings of the parameter. On the basis of the test patterns thus formed the optimum setting of the parameters is determined in accordance with a predetermined criterion. The parameters are adjusted in accordance with said optimum setting during the recording of the information patterns (58, 59). Each time that an optimum setting is determined an auxiliary pattern is formed in an auxiliary area (22) assigned to the calibration area (21), which auxiliary pattern indicates that test patterns are present in the associated calibration area. Each time that the optimum setting is determined the test area to be used is selected on the basis of the auxiliary patterns formed in the auxiliary areas (22a,..., 22d).

Title: Dual port ram and operating method thereof
Inventor: HILTEBEITEL NATHAN R
IPC: G11C11/401
Filed: 1990-11-27
Granted: 1995-01-07
Abstract: A dual-port DRAM in which a single serial latch is shared between two pairs of folded bit lines from two arrays of memory cells (10, 20). A first set of multiplexer devices (14, 24) selects one of the two pairs of folded bit lines from each of the arrays (10, 20), and a second set of multiplexer devices (16, 26) selectively couple one of the remaining folded bit line pairs to either the parallel port or the serial latch for access to the serial port. This arrangement greatly decreases the consumption of chip real estate. At the same time, it makes unlimited vertical scrolling possible through the use of a copy mode that can be carried out in two operating cycles, and facilitates masked writing, while at the same time reducing clocking complexity. <IMAGE>

Abstract: continuously forming a fault prevention film(31) and a oxide prevention film(32) on a semiconductor substrate(300); determining an element region by selectively etching the oxide prevention film(32); forming a field oxide film(33) for isolating the element region; exposing the semiconductor substrate of the element region by forming an etching prevention film(34) over the substrate and removing the etching prevention film(34) located on the element region; forming a gate insulation film and a gate electrode on the resulting structure; forming a spacer on side wall of the gate electrode by depositing a material for the spacer(37) on entire surface of the substrate(300) and dry-etching it. The method enhances characteristic and reliability of the semiconductor device.

Abstract: 휘도신호 성분과 함께 색도신호 성분을 갖는 복합영상신호에 작용하는 다양한 동신호 검출회로에서, 색도신호 성분은 공간 주파수 영역에서 대각선상 고주파수만을 제거하는 소정의 필터로 억제된다. 공간 주파수 영역에서의 대각선상 고주파수는 각국 방송국에서 채택된 것과 같이, 적절한 표준만 따른다면 복합영상신호의 색도신호 성분을 포함한다. 동신호 검출은 공간 고주파수 성분을 보다 많이 포함하므로써 개선된다.

Abstract: The method for producing an inorganic molding material is characterized by mixing 20-25 wt.% inorganic powder of cement, siliceous, limestone, stone or gypsum powder, 50-65 wt.% liquid sticker and 15-25 wt.% glass fiber at room temp. for 5-10 min., and extruding the mixture. The liquid sticker is produced by mixing 90-95 wt.% water and 5-10 wt.% alcohol at 100 deg.C for 5-10 min, mixing 60-65 wt.% mixture and 35-40 wt.% formaldehyde at 90-100 deg.C for 10-20 min, and adding 40-45 wt.% powdery melamine resin to 55-60 wt.% mixture and heating the mixture at 70-90 deg.C for 10-25 min. The molding material has a good heat resistance, weather resistance and soundproof characteristic, is used as an heat insulating material.
