Title: Space forming method in slide fastener's chain
Inventor: SHIRAKAWA HIROSHI
IPC: A44B19/58
Filed: 1984-12-11
Granted: 1986-06-18
Abstract: The method to produce connecting link-free gaps on toothed fasteners involves processing of the finished fastener in several steps. The operation consists of separating the two halves of the fastener followed by placing each half on a working surface(12). All connecting links which have to be removed to create the gap are fixed on the working surface by pressure pieces. The connecting threads enclosed in the connecting links are cut through at the two points representing the beginning and end of the gap. Subsequently the carrying straps are pulled away from the pressure pieces so that the woof threads and the core cord can be pulled out. The connecting links are removed from the carrier straps leaving intact the woof threads, the core cords and connecting threads along the gap.

Title: Primary air exchange for a pulverized coal burner
Inventor: TARUE ALBERT D
IPC: F23K3/02
Filed: 1986-07-16
Granted: 1990-08-27
Abstract: The burner includes a supply line through which a primary air and pulverised fuel mixture is supplied. A separator has its inlet within the supply line and is dimensioned to receive and remove approximately one half of the primary air while the remaining half of the primary air moves past the separator. Additionally approximately 90% of the pulverised fuel passes the separator while only about 10% of the pulverised fuel enters the separator along with approximately one half the primary air. This air and small quantity of fuel mixture is delivered from the separator to a nozzle where it is discharaged into a burner throat of a furnace. Hot air is injected into the remaining mixture of half the primary air plus the large percentage of pulverised fuel to heat this fuel before it is injected into the furnace for ignition.

Title: High speed data transmitting circuit with common input/output line
Inventor: JIN DAE-JE
IPC: G11C11/404
Filed: 1991-08-14
Granted: 1994-09-10
Abstract: The data transmission circuit gives speed-up based on using bit lines directly connected to the gates of output transistors during data transmission in dynamic RAM and gives large scale integration with common I/O lines. The circuit comprises bit lines BL, BL (65)(66) connected to a memory cell (51), transistors (61)(62)(63)(64) for data input, transistors (57)(58) for data output, transistors (53)(54)(59)(60) for separation of electric connection, a transistor (56) for electric discharge to make a voltage level applied to other channel an earth voltage level, a sense amplifier (55) for amplifying the voltage difference between the bit lines BL, BL (65)(66), a signal (CSL) for selecting a memory cell (51).

Abstract: 본 발명은 레이저 다이오드의 제조방법과 관련된 것으로서, 종래에는 이러한 레이저 다이오드 제조공정이 적어도 3회의 에피공정, 1회의 포토에칭 공정, 선택성장의 SiO 2 공정등 많은 제조 공정을 수반하므로서 그 제조과정이 복잡한 것이었고, 한편으로는 소위 COD를 고려한 설계가 아니므로 초고출력을 얻는데 상당한 제약이 뒤따른다는 문제점등이 있었으나, 본발명에서는 이러한 종래 기술의 문제점을 개선할 수 있도록 단순한 공정에 COD등의 현상을 배제하므로서 초고출력 레이저 다이오드를 얻을 수 있도록, n-GaAs 기판(11)을 기재로 하여 그위에 n-AlxGaAs clad층(12), p-AlyGaAs층(13), p-AlxGaAs clad층(14), n-GaAs층(15)을 차례로 성층시키는 제1공정과, n-GaAs층(15)에 역사다리꼴 단면의 골을 내는 포토에칭의 제2공정 및 그위에 다시 p-AlxGaAs층(16)과 p-GaAs Cap층(17)을 성층시키는 제3공정으로 된 레이저 다이오드의 제조방법을 제공하는데 있다.
