Title: Circuit making method for ceramic printed circuit board
Inventor: CHANG AN-JAE
IPC: H05K1/03
Filed: 1988-12-23
Granted: 1992-03-30
Abstract: In the ceramic electronic circuit, the  substrate  is  formed with an aluminum nitride layer and a noble  metal-aluminum  layer, simultaneously, by inter-diffusion of aluminum  and  noble  metal. The fabrication method for electronic circuit  has  the  following processes; (1) forming an aluminum layer on the surface of ceramic substrate by vacuum evaporation or  sputtering  of  aluminum;  (2) spreading photoresist films on the surface of aluminum  except  on the electronic circuit part and forming noble metal layer  on  the electronic  circuit  part;  (3)  heat  treating  it  in   nitrogen atmosphere. It has advantages of increasing thermal conduction  by aluminum nitride layer and reducing surface roughness  of  ceramic substrate by aluminum layer. The substrate is applicable  to  high integrated and functional circuit because it is possible to form a thin film and micro-fabricated circuit.

Title: Making method of ldd structured transistor with multi-channel
Inventor: HWANG I-YON
IPC: H01L21/334
Filed: 1991-07-11
Granted: 1994-05-25
Abstract: implanting an ion having the same conductivity as that of a substrate into the substrate using a gate as a mask, to form a first channel layer; implanting an ion having opposite conductivity of that of the substrate, to form a LDD layer on the first channel layer; forming a gate sidewall spacer, and implanting an ion having opposite conductivity to that of the substrate using the gate and gate sidewall spacer as a mask, to form a source and drain region; implanting an ion having the same conductivity as that of the substrate into the source and drain region using the gate and gate sidewall spacer as a mask, to form a second channel layer bottom of the source and drain region, thereby reducing the short channel effect, and preventing the punchthrough.

Title: Preparation of anthocyan-type red pigment via tissue cultivation of rhaphanus sativus l.
Inventor: LEE KWAN-HO
IPC: C12P19/00
Filed: 1991-08-12
Granted: 1995-05-10
Abstract: The antocyanin in pigments production method from callus of radish such as Rhaphanus sativus L. (I) comprises the steps of (1) culturing seeds of (I) in artificial soils for 15 days, (2) cutting the cotyledons and the roots of cultured (I) on pigment production medium (II) at 24-26'C, below 10,000 lux light at 8 hrs/day for 20 days, (3) extracting pigment as malvidin- 3,5-diglucoside from callus with 1% HCl- ethanol. The callus contains pigments 16.4% in dried weight. The composition of (II) is ammonium nitrate, boric acid, calcium chloride, cobalt chloride, cupric sulfate, solium EDTA, ferrous sulfate, Mg sulfate, Mn sulfate, molybdic acid, potassium iodide, potassium nitrate, potassium phosphate, zinc sulfate, inositol, thiamin, malt extract, sucrose, 2,4-D, kinetin.

Abstract: The lycium extract is produced by (a) adding 1-5 wt.pts. cinnamon bark, 1-5 wt.pts. zingiber, 1-5 wt.pts. jujube and 1-5 wt.pts. glycyrrhiza to 100 wt.pts. lycium, (b) adding an water of ten times the mixture, immersing the mixture in the water at 80-100 deg.C for 5-6 hrs. to extract a lycium component, cooling the lycium extract at 0-10 deg.C for 20-30 hrs., filtering and centrifugally separating the extract to obtain a supernatant, and concentrating the supernatant at 80 deg.C by the vacuum pressure-reduction concentration machine to have 40 % water content. The lycium extract is used as an additive for health foods.
