Abstract: The production efficiency of silicon single crystal produced by additional charge or recharge method is improved by avoiding loss due to undissolved portion of poly-silicon rod supplied in the additional charge or recharge. A poly-silicon rod 20 as an additional charge is brought down in a silicon melt 11 in a crucible 10, while being directly supported by a seed crystal 40. The poly-silicon rod 20 is brought down to be totally supplied to the silicon melt 11, and then silicon single crystal 44 is pulled using the seed crystal 40.

Abstract: 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.

Abstract: A jig used for heat treatment made from an SiC-coated silicon carbide material, wherein the SiC film is coated by the CVD method on a silicon carbide matrix in which silicon has been impregnated and wherein there are no pores with a diameter of 2 .mu.m or larger in the outer layer of the matrix within 200 .mu.m from the interface of the SiC film and the silicon carbide matrix when observed by a scanning electron microscope at a magnification of 400 times. The jig is manufactured by producing an SiC film on the surface of a silicon carbide matrix in which silicon has been impregnated by introducing a raw material compound for producing the SiC film and forming the SiC film at a temperature from 1000.degree. C. to 1290.degree. C. under a pressure from 500 to 760 Torr in a non-oxidative atmosphere. The jig exhibits superior resistance to high temperature heating cycles and excellent high thermal shock resistance required for heat treatment in semiconductor manufacturing.

Abstract: In a telecommunications network in which a plurality of switching nodes are interconnected via links each composed of a plurality of trunks and are each connected to a network control center via a control signal link, the network control center determines for each switching node a predetermined number of alternate routes for each first route on the basis of traffic data in the telecommunications network and supplies them as a set of available alternate routes to the switching node. The switching node assigns one or more of the available alternate routes in advance. The switching node responds to a call-connection request to try to connect the call to the first route, and when having failed in the call connection, the switching node retries the call connection through one of the assigned routes.
