Title: Color crt
Inventor: DAKENAKA SIGEO
IPC: H04N9/28
Filed: 1986-04-17
Granted: 1990-03-12
Abstract: The apparatus comprises a vacuum envelope with a faceplate. An electron gun is arranged in the vacuum envelope in a position facing the faceplate.  A cathode emits a single electron beam and an electrode accelerates and converges the beam.  A screen formed on the faceplate includes a phosphor elements for emitting different coloured light rays upon landing of the electron beam.  A shadow mask selects the beam and directs it toward the screen and causes the beam to land on a predetermined phosphor element. Auxiliary and main deflectors provide the beam with small stepped diflections.

Inventor: KOUICHI HIROOKA
IPC: C23C8/04

Granted: 1996-11-18
Abstract: A sticker composed of a carburization, nitridation or oxidation preventing layer prepared by binding heat-fusible or heat-meltable particles which can prevent carburization, nitridation or oxidation with one another by using a heat-decomposable resin as a binder and a self-adhesive layer, and its use for that purpose. When this sticker is fastened to that part of a metallic member which must be prevented from being carburized, nitrided or oxidized in carburizing, nitriding or heat-treating the member, the covered part remains unmodified to retain toughness, while the surface of an uncovered part is modified, e.g. hardened. Thus it becomes possible to obtain machine parts having both toughness and wear resistance. Since the sticker is of self-adhesive type, it can fulfill its purpose merely by sticking it to a desired part.

Title: Silicon analysis method included in alloy
Inventor: KWAK CHOL
IPC: G01N33/20
Filed: 1991-12-27
Granted: 1995-04-28
Abstract: The method improves the degree of accuracy in analyzing silicon and the reproductivity by ionizing all silicon in the alloy containing silicon content. The method comprises (A) ionizing the specimen containing silicon; (B) converting the ionized silicon to silicon dioxide; (C) separating silicon and silicon dioxide from the solution; (D) heating and ionizing the mixture of silicon, silicon dioxide and boric acid in the furnace; (E) filtering the deposited silicon dioxide and measuring the weight.

Title: Semiconductor memory device and fabricating method thereof
Inventor: BAE DONG-JU
IPC: H01L27/11
Filed: 1992-03-13
Granted: 1995-10-07
Abstract: The semiconductor memory comprises a first memory cell which has first and second active regions formed on its upper side and lower side, resp.; first and second word lines which are vertically extended to the adjacent memory cells on the right and left sides of the memory cell; first and second driving transistor gates formed in the memory cell for each of the first and second memory word lines; a first power line inter connecting the second active region with the first active region; second and third power lines arranged in parallel to the word lines and the gates of the driving transistors; a first node connected to the second power line and a second node connected to the third power line; a third node connected to the first node and formed in intersection with the nodes and a fourth node connected transversely to the second node; and first and second bit lines arranged in the upper and lower sides of the memory cells, respectively.
