Abstract: PCT No. PCT/CH97/00055 Sec. 371 Date Oct. 5, 1998 Sec. 102(e) Date Oct. 5, 1998 PCT Filed Feb. 18, 1997 PCT Pub. No. WO97/37922 PCT Pub. Date Oct. 16, 1997The invention concerns a control system for a plurality of groups of lifts (G1-G5), according to which system the passenger can input his destination at any destination call input device (TE) without having to know which group of lifts (G1-G5) serves the desired storey. In this way, in large buildings in which, for structural reasons, the ranges of storeys served by individual groups of lifts (G1-G5) are disposed adjacent one another in a confused manner, the passenger's search for the appropriate lift is facilitated. The multiple groups control system always selects the most favorable lift from all the available lifts and, when the storey ranges served by a plurality of groups of lifts (G4-G5) overlap, the selection is made from all the possible lifts. If the passenger has to change lifts, the connecting lift is shown on a display.

Title: 내부 전체의 온도를 동일하게 할수 있는 소형포장상자
Filed: 1999-02-23
Abstract: 본 발명은 포장상자에 농산물을 포장하여 저온으로 보관을 할 때에 포장상자의 내부의 온도가 골고루 일정하게 유지될수 있도록 하기 위한 내부 전체의 온도를 동일하게 할수 있는 소형포장상자에 관한 것이다. 
     일반적으로 농산물을 포장하는 포장상자는 소형포장상자와 대형포장상자가 있으나, 이와 같이 대형포장상자와 소형포장상자는 농산물을 일정하게 포장을 할 수 있도록 후지재나 발포성합성수지재로서 포장상자를 형성하여 오고 있는 실정이다. 
     이와 같이 후지재나 발포성합성수지재로 이루어진 포장상자는 상부가 개방되거나 덮을수 있도록 하고, 사각형상으로 이루어져 있으며, 외측으로는 통공을 형성하여 포장상자내로 공기나 유통이 되도록 하여 내부에 포장한 농산물이 상하게 되는 것을 방지하도록 하고 있는 실정이었다. 
     그러나 이와 같은 사각형의 포장상자는 단일개로서는 포장된 농산물을 장기간 상하지 아니하도록 하면서 보관을 할수 있으나, 다수개를 사방으로 쌓아서 보관을 할시에는 포장상자간의 공간이 없게 됨으로서 내측에 적재한 포장상자에는 신선한 공기가 흐르지 아니하게 됨으로서 내측의 농산물은 쉬 상하게 되는 문제점이 있었다. 
     그러므로 사각형으로 형성한 포장상자를 적재 보관을 할 때에는 상자와 상자간을 지그재그로 적재를 하여 상자간의 간격을 유지하도록 함으로서 좁은 공간에 많은양의 포장상자를 적재할수 없었고, 포장상자를 균형을 잡아서 제대로 적재를 하지 못하면 적재된 포장상자까 무너지게 되었으며, 이로 인하여 농산물을 포장한포장상자를 적재보관하기 위해서는 넓은 공간을 필요로 하게 되었음과 동시에, 적재할때에 숙련된 적재자만이 적재를 할수 있는 등의 문제점이 있었다. 
     본 발명은 포장상자를 상광하협 형상의 사다리꼴로 소형포장상자를 형성함으로 적재할면 소형포장상자간의 공간을 유지할수 있도록 하여 내측으로 적재되어 있는 포장상자에도 신선한 공기가 흐르도록 함으로서 농산물이 상하지 않는 상태로 장기간 포존할수 있도록 하고, 상협하광 형상의 대형 포장상자에 포장을 하더라도각각의 포장상자간의 공간을 유지할수 있도록 하여 농산물을 저온 보존이 가능하도록 하기 위한 것이다.
