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 and a driving mechanism is positioned between an inner wall of the elevator path and a space occupied by an elevator car rising and falling in the elevator path . One end of a suspension rope is fixed to the elevator car in a position below a ceiling of the elevator car . With the arrangement, the car can move close to the ceiling of the elevator car effectively. Further, it is possible to reduce respective heights of the elevator path and a building equipped with the elevator apparatus.

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.

Adaptive routing control method

A rubber composition having excellent adhesion to steel cords comprising:

Rubber composition

A pneumatic tire having improved heat resistance and gripping performance is obtained by using as a tread rubber a rubber composition containing particular amounts of specified p-phenylene diamine derivative and specified carbon black.

Pneumatic tires

A rubber-cord composite body used for cord reinforcing rubber articles is produced by embedding fiber cords treated with an epoxy compound and further with a particular resorcin-formaldehyde-rubber latex adhesive into a particular rubber composition containing 0.5.about.10 parts by weight of each of a bismaleimide compound and sulfur.
