Abstract:
An oil supply passage (68) is formed inside a rotating shaft (56) of a compression mechanism (2f). An oil supply passage (38) is formed inside a rotating shaft (36) of an expansion mechanism (22). A boss portion (81) is provided at a lower end of the rotating shaft (56). A shaft portion (82) that is engaged in the boss portion (81) is provided at an upper end of the rotating shaft (36). The circumference of a coupling part (80), which includes the boss portion (81) and the shaft portion (82) is covered by an upper bearing (42) of the expansion mechanism (22). The upper bearing (42) supports both the rotating shaft (36) and the rotating shaft (56).
Abstract:
Aconventional human body sensing systemusing a tremor sensing-type human body sensor within a house has a problem such that the system cost becomes high because two human body sensors in each room or one human body sensor in each room plus one human body sensor in a corridor are used in order to sense a stationary person in a room so as to carry out a room exit determination. In a room exit determination part 250, a determination of presence is made in the case that a movement pattern vector consisting of the room ID of movement origin, the room ID of movement destination and the movement period of time is not received from the non-specified room response sensing part 230 within a predetermined period of time and a determination of exit from the room is made only when the movement period of time in a movement pattern vector agrees with the movement period of time of past exits from the room stored in the movement time storage part 240 in the case that this vector is received from the non-specified room response sensing part 230.
Abstract:
Heretofore, in a dispersed energy supplying system, the unit cost of energy generated in houses and the unit rate of energy bought from an electric power company, etc. have been compared, but consideration has never been made of environmental burden. There are provided a controlling portion 11 of controlling the operation of a fuel cell, a switch 30 of selectively supplying the electric power of the fuel cell or an external electric power into an electric power load, an electric power generation unit cost calculating portion 13 of calculating the electric power generation cost of the fuel cell, an electric rate system storing portion 14 of calculating the cost of a power plant 50 and a dispersed electric power generating apparatus 51, an LCA data storing portion 16 of storing LCA data of the fuel cell, the power plant 50 and the dispersed electric power generating apparatus 51, and a user interface portion 20 of presenting electric power generation cost, external electric power cost and LCA data and allowing the user to determine the controlling operation of the aforementioned controlling portion 11 and/or the selecting operation of the switch 11.
