Abstract: A scheme for providing environmental information to users is disclosed. In this scheme, environmental information is measured automatically by each of a plurality of environment sensors arranged at a plurality of regions, and the environmental information measured by each environment sensor is collected automatically to a base device, and stored at the base device. Then, the environmental information is processed at the base device according to a user information of an individual user, and processed environmental information is provided from the base device to the individual user through a network connecting the users and the base device.

Abstract: A swash-plate type compressor for air conditioning of vehicles. A pair of cylinder blocks are rigidly combined in coaxial alignment. The combined cylinder blocks form three bores. A piston is slidably disposed in each bore and the motion of each piston is actuated by a swash-plate mechanism mounted on a drive shaft which is connected to a driving source. A lubrication reservoir is formed in a sector space sandwiched by a pair of said bores and an inside wall of said combined cylinder block. A geometrical longitudinal center line of said combined cylinder block is biased downward from a geometrical center line of said drive shaft.
