摘要:
The present invention provides an automotive inner ceiling material difficult to deform at a high temperature. Sheath-core type conjugate polyester fibers are prepared. The sheath is a heat fusible component. The core is a non heat fusible component. The sheath is made of copolyester which comprises acid units made of terephthalic acid and diol unites made of ethylene glycol and 1,4-butanediol. The conjugate fibers and the main fibers of polyester are mixed and provided in a card machine to be opened and accumulated to obtain a fibrous web. The fibrous web is heated to melt the sheaths, which are thereafter solidified to bind the fibers to obtain a non woven fabric. The nonwoven fabric is heat-treated at a temperature equal to or higher than the melting point of the sheath. Immediately thereafter, the nonwoven fabric is heat-molded between a pair of a mold plates. During the heat-molding process, the inner temperature is maintained at 100˜130° C. for 60 seconds to obtain the ceiling material.
摘要:
An elevator apparatus is provided with an elevator path having a restricted height. Under a roping ratio of 1:1, a thin driving unit having a traction sheave 1 and a driving mechanism 2 is positioned between an inner wall 3a of the elevator path 3 and a space occupied by an elevator car 4 rising and falling in the elevator path 3. One end of a suspension rope 7 is fixed to the elevator car 4 in a position below a ceiling 4c of the elevator car 4. With the arrangement, the car 4 can move close to the ceiling 4c of the elevator car 4 effectively. Further, it is possible to reduce respective heights of the elevator path 3 and a building equipped with the elevator apparatus.
