Granted: 1990-08-27
Abstract: The transportation system comprises a guide rail composed of main lines and branch lines, intersecting one another, a coupling section connecting the main and branch lines, and a carrier for carrying cargo, the carrier being capable of running along the guide rail. The carrier is kept floating, in a non-contact manner, from the guide rail, by electromagnetic attractive fcrce. A transfer apparatus is provided at the coupling section. At the coupling section, the carrier, having so far been running along the main lines, is stopped, and is then transferred from the coupling section to the branch lines, all in a non-contact manner. Thus, the mounting space of the transfer apparatus is small.

Title: Transmission system using forward error correction
Inventor: GROVER WAYNE DAVY
IPC: H04J3/07
Filed: 1987-07-09
Granted: 1996-01-15
Abstract: In a high-speed fiber-optic tranmission system, data streams are synchronized using fixed stuffing before being multiplexed for transmission. The fixed stuffing information is replaced with forward error correction (FEC) information, whereby FEC is effected without any increase in transmission speed. FEC information blocks of each data stream can be synchronized to the frame timing of the transmission system, or they can be relatively unsynchronized. In the latter case, an FEC decoder acts in a self-framing manner to synchronize itself to the FEC information blocks of the respective data stream.

Abstract: The width of electrode grid of solar cell is adjusted to receive light optimally so that a series resistance is decreased. The front electrode is formed on n+ plate and the backside electrode is formed by thermal processing a aluminium past and a bus bar is formed on a front panel of a solar cell. The front electrode is formed into the grid structure with 0.05-0.3 mm in width so that a light receiving area becomes 85-95 % of the whole solar cell area.

Abstract: The unit compensates a leakage color in color filter gaps and improves a purity of color. The unit forms color filters (7)(8) in between driving cell (2) and compensated cell (3'). Color filter (8) lies between color filters (7) of driving cell (2) and also lies alternately at the same intervals as those of the filters (7) in color filter (7) of driving cell (2). A driving cell (2) of color filter (8) equalizes the width (b') of color filter (7). The unit improves a color purity of R,G,B in color liquid crystal display unit to compensate a leakage color in color filter ,and a color spread by distribution of wavelength Δn.

Abstract: 본 발명은 다양한 절삭인서트, 끼움쇠, 및 체결장치를 수용하도록 설계된 콤비네이션 공구홀더에 관한 것이다. 그 공구 홀더는 절삭인서트(34)를 지지하는 끼움쇠(50)를 지닌다. 부싱(44)은 보어(18)내로 장전되며, 끼움나사(48)는 끼움쇠(50)를 홀더(12)에 체결시킨다. 끼움쇠와 끼움쇠 체결조립체는 끼움쇠  베어링 표면을 최대화하도록 설계되어 깨지기 쉬우며 비교적 낮은 횡단 파괴강도를 지닌 절삭인서트를 적절하게 지지한다.
