Abstract: A physical condition management system detects during-sleep biomedical information while the driver is sleeping and during-drive biomedical information while the driver drives a vehicle. A during-sleep physical condition information calculating section calculates during-sleep physical condition information from during-drive physical condition information and/or the during-drive biomedical information, and the during-sleep biomedical information. A during-drive physical condition information calculating section calculates the during-drive physical condition information from the during-sleep physical condition information and/or the during-sleep biomedical information, and the during-drive biomedical information. The sleep support operation is controlled according to the during-sleep physical condition information and the drive support operation is controlled according to the during-drive physical condition information.

Abstract: A compressor integral with a Stirling engine having a pressure space comprises a housing, a partition wall provided in the housing, a first pressure chamber defined in the housing at one side of the partition wall and connected with the pressure space of the Stirling engine, and a second pressure chamber defined in the housing at the other side of the partition wall and connected with the first pressure chamber via an orifice. A rod passes through the partition wall and has a first end and a second end located in the first pressure chamber and the second pressure chamber, respectively. A third pressure chamber is defined by a first plate which is connected to the first end of the rod and a first bellows located between the first plate and the partition wall. A fourth pressure chamber is defined by a first plate which is connected to the second end of the rod and a second bellows located between the second plate and the partition wall.

Abstract: A sanitary device of the type associated with a toilet bowl and having an extendable and retractable spray arm is provided with a hot water supply tank having a heating element therein. The pressure of the cold water supply forces the heated water through the spray nozzle and a partition is provided within the tank between the cold water inlet and the hot water outlet to prevent cold from being inadvertently forced through the hot water outlet.
