摘要:
Provided is an electricity collection and distribution ring excellent in durability and the easiness of manufacturing while the size thereof is reduced, and also provided is a method for manufacturing the electricity collection and distribution ring. The electricity collection and distribution ring (2) comprises: first to fourth bus rings (21 to 24) for collecting electricity from and distributing electricity to each of the phase coils (111, 112, 113) of a three-phase motor (1); a plurality of fixing members (3) disposed at a plurality of predetermined positions in a circumferential direction of the first to fourth bus rings (21 to 24) and mutually fixing the first to fourth bus rings (21 to 24); and a plurality of connection terminals (4) for connecting the first to fourth bus rings (21 to 24) and the lead-out lines of the respective phase coils (111, 112, 113). The fixing members (3) integrally have a locking portion (30) for, among the first to fourth bus rings (21 to 24), locking the first bus ring (21) positioned at an end in an axis direction and a fixing portion (31) for mutually fixing the other second to fourth bus rings (22 to 24) by molding.

Provided is an air-blowing-type road surface snow-melting system which makes it possible to reduce the height of a hollow roadbed body while also making the amount of air blown out from an air-permeable structure substantially uniform. An air-blowing-type road surface snow-melting system (1) comprises: a hollow roadbed body (2) which is provided with a hollow section (21) and is buried beneath a road surface; an air-permeable structure (3) which is disposed on the hollow roadbed body (2) to form the road surface; and a vent pipe (4) which is laid inside the hollow section (21) of the hollow roadbed body (2), wherein the vent pipe (4) is laid in the shape of a loop so as to enclose a predetermined snow-melting area and in addition a plurality of blow-out sections (42) which open toward the inside of the loop are disposed in the vent pipe (4).

摘要:
A mobile communication system includes a mobile terminal, a base station, and a mobile switching station. The mobile terminal, the base station and the mobile switching station are constructed so that communication information and control information are transferred by an asynchronous transfer mode (ATM) cell between the mobile terminal and the base station, between mobile switching station and the base station.
